ลวดเชื่อม / แท่งเชื่อม ต้องเผ็นเชื้อเดียวกับ HDPE sheet
ปกติท่อ HDPE ใช้เครื่องดึงไฮดรอลิค ดันท่อ หรือ ดึงแผ่น Sheet เข้าหากัน แล้วเชื่อมไฟฟ้าให้ความร้อน หลอมเนื้อท่อของตัวมันเองให้ติดกัน
แต่ถ้าจะเชื่อมด้วยหัวแก็สพ่นเปลวไฟ ก็ต้องทำการทดสอบก่อนว่าจะทำเองที่หน้างานได้หรือไม่ ?
แท่งเชื่อมที่ผมมีอยู่ เป็นชนิด Casting PE type I ( 100% Pure Polyethylene Resin ) และ type II ( 80% Modified Polyethylene Resin ) ก็สามารถเชื่อมติดกับ High Dense Polyethylene Resin ได้ แต่ต้องระวังต้องค่อยๆเดินรอยเชื่อม เพราะจุดหลอมตัวไม่เท่ากัน แต่ก็หลอมติดกันได้ เพราะเป็น Polyethylene Based Resin เหมือนกัน
ถ้าไม่แน่ใจ ก็ต้องเรียกผู้รับเหมาเชื่อม แต่เขาคิดแพงมาก เพราะเป็นงานนอกสถานที่ และ อยู่ไกล

SW-9610 A/B Ultra High Equivalent Weight ( Vitrious) Epoxy was released before the year 2000 while SW-626 A/B has been used here in the year 2004.
Suggested to make the SWANCOR EX-6920 FRP lamination with 3.2 mm. thickness (M/M/M) for < 5 Q tank capacity upto 4.5 mm. thickness (M/M/M/M) for > 5 Q tank capacity.

SW626 A/B + C-type Glass Flake also can be applied by Plural Spray gun with Gel Coater machine for coating into the complicated 3D ( three dimensions ) shape area.
พื้นที่เคลือบด้วย SWANCOR EX6920-03.2 ทน 98% Conc. Sulfuric Acid ( 98% H2SO4 )
หลังจากใช้งานไปแล้วเกิน 1 ปี ดูสภาพแล้วก็ยังใช้ได้ แต่ก็ต้องลงใหม่ทับหน้าใหม่ ทุกๆ 2 ปี เพราะทับหน้า Top Coat จะใหม้เกรียมหมด แต่เนิ้อ Laminate ด้านในยังป้องกันได้
การละลายของ SW626 A/B Vitrious Epoxy เมื่อถูก Attasck by 98% Con. Sulfuric Acid ( H2SO4) โดยประมาณ = 2 % weight ต่อ 60 วัน
ดังนั้นถ้า เคลือบพื้นชั้นเนื้อของ SW 626 A/B จเหลือะสภาพ 60% ต้องใช้เวลาประมาณ = 60/2 x 60 = 1,800 วัน หรือ 5 ปี
แต่ถ้าใช้งาน Inside Tank Lining การ Attasck ของ SW626 A/B by 98% Con. Sulfuric Acid ( H2SO4) จะรุนแรงกว่างานเคลือบพื้น ต้องเผื่อความหนาชั้น SW626A/B Chemical Barrier ให้มากๆ เข้าไว้ หนากว่าเคลือบพื้น 2 – 3 เท่า
สรุปแล้ว Corrosion Protection for 98% H2SO4 inside tank lining มี Choice ให้เลือก 2 ระบบ คือ :-
(1) HDLPE ( หรือ HDPE Type I และ Type II ) Inside Tank Lining
PE sheet หนา 3 มิล สำหรับ 3Q Tank
PE sheet หนา 5 มิล สำหรับ 6Q Tank
PE sheet หนา 10 มิล สำหรับ 10Q Tank

Lactic Acid_SWANCOR_CHEMICAL RESISTANCE GUIDE
For your information on Design of Pure LacticAcidFermentation Tank Lining. Lacticacid is also known as milk acid. Lacticacid is mainly found in sour milk products. The casein in fermented milk is curdled by lacticacid. Lacticacid may also be found in many processed foods. Pure Latic Acid is an initiator for many of human foods , Animal Foods , Phramaceuticals and Medical products etc.
So, the tank lining material for Pure LacticAcid must be complied to US FDA and Thai FDA ( Food and Drug Administration ) otherwise you would be claimed by FDA law enforcement later.
As we known about Lactic AcidFermentation Tank Lining materials :-
All Expoxy => NR ( Not Reccomended ) because of Carcinogen / Toxic Resin Excuse ( containing of Amine and Amide in Curing agents )
All Orthophathalic Unsaterated Polyester Resins => NR ( Not Reccomended ) because of Toxic Resin Excuse ( containing of Orthophathalic ……Extraction )
Due to Pure Lactic Acid is an initiator for many kind of human foods , Phramaceuticals and Medical products etc. Hence , all inside tank lining material for Pure Lacitic AcidFermentation must be complied to HIPPA Health Insurance Portability and Accountability Act of 1996 (“HIPAA”). The Privacy Rule …. they are providing these processing services to a health plan or health care …
Our suggestion for you is you must wait for the recomendation on lining design structure before starting the project. Please await and study more in details before starting the operation.
Use of organotin esterification catalysts for reducing extractability
Abstract of EP0419254 Organotin catalysts containing at least one direct oxygen-to-tin bond and one direct carbon-to-tin bond, e.g. hydroxybutyltin oxide, monobutyltin tris (2-ethylhexanoate), dibutyltin oxide, are use as esterification catalysts in the production of polyester and polyester-containing compositions and articles. Articles made from such polyester and polyester-containing compositions have low extractable toxicity and are suitable for use in regulated food, beverage, pharmaceutical, and medical-device applications.

Description:
The present invention relates to the use of organotin esterification catalysts in the production of polyester and polyester-containing compositions for reducing extractability of catalyst components from a polyester article in contact with food, beverages, pharmaceuticals, or from a medical-device. It is well known that organotin compositions, including organotin oxides, hydroxides, alkoxides and carboxylates, are effective as catalysts in the manufacture of polyester resins and polyester-containing compositions. The use of tin catalysts in the esterification of polyesters is discussed in US-A-2,720,507, 3,345,339, 4,554,344 4559945 and 2720501 and EP-A-299730 and Research Disclosure 28371. The organotin catalysts decrease the time required to complete esterification or transesterification and to effect complete reaction. Polyester resins and compositions are useful in the manufacture of textiles, coatings, packaging and molded articles. A major application area is in the production of coatings and packages for storing and handling of foods, beverages, and pharmaceuticals and as components of medical devices. When used in such applications, the polyester compositions, and the articles made therefrom, need to be “non-toxic”, that is, safe for use by consumers when used for their intended purpose. The compositions and their components generally require the approval of appropriate health-regulatory agencies, such as the U.S. Food and Drug Administration (USFDA). To obtain such approval, prospective users often have to conduct extensive tests, which are both time-consuming and expensive. Organotin catalysts of the type employed herein have not yet been publicly sanctioned by the USFDA for use in the manufacture of polyesters intended for regulated “food-grade” (as defined by the USFDA) uses, such as food, beverage and pharmaceutical handling and packaging, or medical devices which come into contact with body fluids. Therefore, manufacturers of regulated food-grade polyester resins and polyester-containing compositions, as well as those who fabricate regulated articles therefrom, may resort to less-efficient catalysts or use no catalyst at all. However, the use of less-efficient catalysts, or no catalysts at all, can result in long reaction times with increased costs and energy consumption. Some users have relied on the assumption that there is zero extraction of the catalyst from contact surfaces into foods, beverages, pharmaceuticals, and body fluids, and that therefore the catalyst is not a “food additive” (as defined by the USFDA), and requires no regulatory sanction. This is, however, an untenable position. Reliance on the assumption of zero extraction of the catalyst from such polyester articles without further testing is faulty, because the extractability of such catalysts from polyester articles into the wide variety of foods, beverages, pharmaceuticals, and body fluids with which they may come into contact is not known, particularly for articles intended for repeated use. A more desirable situation is one in which the toxicity and extractability of the catalyst has been fully explored and reviewed by scientists experienced in chemistry, polymerization and toxicology so that a scientific judgment can be made and regulations can be published by the appropriate regulatory agency for general use by the public. Such regulations can state the composition of the catalyst material, the purity of the catalyst, the polyester resins and compositions in which the catalyst may be used, acceptable use levels of the catalyst, extraction testing procedures, and extraction limitations. Where the evidence submitted to the regulatory agency clearly demonstrates that the catalyst is of exceptionally low toxicity and only extractable in minute amounts under representative conditions of use in finished articles, the regulatory agency, for example, the USFDA, may conclude that the catalyst material may be used for its intended technical effect without requiring additional extraction testing by particular users, such as polyester manufacturers and article fabricators. Aspects of the invention are set out in the claims. Preferably, the non-toxic organotin catalysts used in the present invention have an LD 50 of at least 0.75 grams/kilogram (g/kg) when fed to rats, and an extractability from polyester and polyester-containing compositions and articles of not more than 200 ppb (billion = 10 9 ) when extracted with water, corn oil, or heptane, using the procedures taught in Title 21 of the U.S. Code of Federal Regulations. In addition, the catalysts preferably have a triorganotin content of less than about 5 percent, and a heavy-metal content of less than about 200 parts per million (ppm). Furthermore, each component organotin compound has a purity of at least 90 percent. The non-toxic organotin catalysts used in the present invention are suitable in the production of non-toxic polyester resins and compositions intended for contact with foods, beverages, and pharmaceuticals and in medical devices. The organotin catalysts are of sufficiently low toxicity, low extractability, and high purity to allow their use in such polyesters without further extraction testing by the users. Polyester-containing articles are preferably in the form of coatings, bottles, packages, tubes, molded products, textiles, and film and sheet intended for packaging and handling foods, beverages, and pharmaceuticals, and for use in medical devices. The polyester article is characterized by extractability of the residual catalyst at levels acceptable to government regulatory agencies without resort to further extraction testing, typically 200 ppb or less. The process for the manufacture of non-toxic polyester resins and polyester-containing compositions comprises the step of catalyzing a polyester esterification or transesterification reaction with the organotin catalysts described herein, leaving residual catalyst in the polyester article. The organotin catalyst for preparing polyester resins is employed at a concentration of about 0.01 – 1.0 percent by weight (wt. %) based on the weight of polyester resin. (All percents herein are expressed as percents by weight, unless otherwise indicated.) A preferred concentration is about 0.05 – 0.2 wt. %. It may be advantageous to use a mi
xture of such catalysts. Therefore for purposes of this application, reference to “a catalyst” in accordance with this invention is intended to denote reference to one or more catalysts. The organotin catalysts used in the present invention are hydroxybutyltin oxide (also known as butylstannoic acid), monobutyltin tris (2-ethylhexoate), and dibutyltin oxide. The triorganotin content of the catalyst used in the present invention should preferably be less than about 5 percent. Triorganotin compounds are often undesirable byproducts in the manufacture of other organotin compounds. Because triorganotin compounds are generally considered toxic, their content in the catalyst should be minimized. Heavy metals are also undesirable impurities, and, therefore, the heavy-metal content of the catalyst is preferably less than about 200 parts per million (ppm).
Toxicity Studies:
The LD 50 test procedure was as follows: Albino rats were administered the test materials by oral intubation. Following dosing, the rats were housed with food and water. Observations were made periodically during the first day and daily for fourteen days following. The results were as follows:

Butyltin tris (2-ethylhexoate)
>3200 mg/kg
Dibutyltin oxide
>794 mg/kg
Extraction Studies:
Polyester resin was prepared from the reaction of isophthalic acid, maleic anhydride, propylene glycol and dipropylene glycol with and without tin catalysts. At the completion of the esterification reaction, the resin was diluted with styrene. Polyester plaques were prepared from these resins by addition of a peroxide to catalyze the reaction of the maleate unsaturation with styrene. Extraction studies were conducted using corn oil, water and heptane as the extractants. The corn-oil extraction studies were carried out by exposing the plaques to corn oil at temperatures from -18°C to 190°C for 45 minutes. Organic matter in the oil extract was destroyed by acid digestion, and the amount of tin extracted was determined by atomic-absorption spectroscopy. The water-extraction studies were carried out by exposure of cured plaques to water in a sealed vial at 190°C for three hours and at 160°C for ten days. The water extract was then analyzed for tin by atomic-absorption spectroscopy. The heptane-extraction studies were carried out by exposure of the cured plaques to heptane at 130°C for two hours. The heptane extract was then analyzed for tin by atomic-absorption spectroscopy. The results of the extraction studies are shown in Tables 1, 2, and 3 below.

While the inventors do not wish to be bound by any particular theory related to the surprisingly low extract-ability of these organotin catalysts, it is proposed that the minute quantities extracted, 200 ppb or less, may be due to conversion of these organotin catalysts containing at least one carbon-to-tin bond to inorganic tin compounds at the elevated temperature at which the polyester is produced. Alternatively, these organotin catalysts containing at least one carbon-to-tin bond may be tightly bound in the polyester matrix either chemically or physically. Whatever mechanism is responsible, the minute extractability by oil, water and heptane make these catalysts suitable for use in non-toxic polyester-containing compositions intended for use in regulated food, beverage, pharmaceutical, and medical-device applications.
Polyester Definition
Polyesters used are generally the polycondensation product of one or more polyfunctional carboxylic acids, acid anhydrides, or esters with one or more polyhydroxyl alcohols. In addition there may be a monofunctional acid or alcohol end group. Linear polyesters are prepared from the polycondensation of a dicarboxylic acid with a glycol. When a portion of the alcohol or acid components has a functionality greater than two, the structure may be cross-linked. The acid and alcohol components may be aromatic, aliphatic, or mixed aromatic and aliphatic. Among the acceptable components are those listed in various USFDA regulations in Title 21 of the U.S. Code of Federal Regulations (CFR), including 21 CFR 177.2420 (a)(1), 21 CFR 175.300 (b)(3)(vii)(a) and (b), 21 CFR 175.320(b)(3), 21 CFR 176.170(a)(5) and (b)(2), 21 CFR 177.1590(a), 21 CFR 177.1660(a), and 21 CFR 177.1680(a)(2). In addition, monobasic acids, listed in 21 CFR 175.300 (b)(3)(vii)(b), may be used as chain stoppers. In addition, the polyesters may be those described in 21 CFR 177.1240 and 21 CFR 177.1315. The mole ratio of hydroxyl groups to acid groups theoretically is one to one; however, excess hydroxyl or acid groups may be used, depending on the end use of the polyester. The tin catalysts are used in the esterification reaction in the manufacture of polyester resins. These re
sins may be used directly by thermoforming or may be cured by reaction with a cross-linking agent using an appropriate catalyst which may or may not contain tin. Preferred polyesters for forming non-toxic compositions with tin catalysts include:
isophthalate-propylene glycol-maleate copolymer cured by reaction with styrene and peroxide-based catalyst;
polybutylene terephthalate;
polyethylene terephthalate; and
the reaction product of 2,2,4-trimethyl-1,3-pentanediol, trimethylol propane, isophthalic acid, and adipic acid cured with a cross-linking agent.
Examples of Catalyst Use in Resin Synthesis:
The importance of catalyst use in decreasing reaction time is illustrated by the following example: Into a 2-liter, 3-neck reaction flask equipped with an N 2 inlet tube, air stirrer, pot thermometer, partial steam-heated condenser, and a receiver with full condenser, the following reagents were charged:
Propylene glycol
4.4 moles (334 g)
Isophthalic acid
2.0 moles (332 g)
The reaction mixture was heated to a maximum temperature of about 220°C, driving off the water of reaction. When the acid number, determined by titration with alcoholic KOH, reached approximately 10 milligrams KOH per gram (mg KOH/g) of sample, the reaction mass was cooled to about 160°C and 2.0 moles (196 g) of maleic anhydride was added. The reaction mass was heated again to about 220°C and reaction continued, with removal of water, until the acid number reached 25 mg KOH/g sample. A second reaction was carried out in the same manner, except that 0.86 g hydroxy monobutyltin oxide (MBTO) (0.20 mole % of initial charge) was added initially. The reaction times for the two procedures are shown below:

Similar reductions in reaction time were obtained in comparative tests using equivalent molar amounts of dibutyltin oxide and monobutyltin tris (2-ethylhexanoate) as the catalysts.
Synthesis of Typical Organotin Compounds:
Synthesis of organotin compounds is usually carried out by the condensation reaction of R m SnCl 4-m with the acid or sodium salt of the desired OX groups, followed by washing with water and drying. Typical examples follow:
Dibutyltin oxide (DBTO):
Dibutyltin oxide is produced by the reaction of dibutyltin dichloride of at least 95% purity with an aqueous solution of sodium hydroxide. The product is washed with water, centrifuged, and dried. A yield of 99%, based on the dichloride charge, is expected. The purity is typically at least 95%, with less than 1% tributyltin oxide, less than 1.5% monobutyltin oxide, less than 1% moisture, and less than 200 ppm heavy metals.
Hydroxy monobutyltin oxide (MBTO):
MBTO is produced by the addition of an aqueous solution of monobutyltin trichloride of 95% purity to an aqueous solution of sodium hydroxide. The product is washed with water, centrifuged, and dried. A yield of about 95% is expected. The MBTO is generally at least 95% pure, with typical impurities including dibutyltin oxide, tributyltin oxide, moisture, and less than 200 ppm heavy metals.
Butyltin tris (2-ethylhexanoate):
Butyltin tris (2-ethylhexanoate) is produced by the reaction of aqueous monobutyltin trichloride of 95% purity with the sodium salt of 2-ethylhexanoic acid. The liquid product is separated, vacuum-stripped, cooled, and filtered. A yield of 98% is expected. The purity is typically at least 95%, with impurities including di- and tributyltin 2-ethylhexanoates,2-ethylhexanoic acid, and less than 200 ppm heavy metals.
