Complex process of PPS coating

Ideal anti-corrosion materials, lame, boring and steel lead to a good end table, do not raise off Chiang. * Lead itself, good compactness, can be effective: spit structure to prevent the infiltration of trichloro aldehyde tolerance and can adapt to the tower above the reactor {o0 ℃ health defecate temperatures, excellent toughness of lead can be used for other temperature difference between the coating and steel Lu buffering stress and deformation. As long as the structure of the tower reactor design to emphasize the anti-corrosion coating with the other protected the tt't9 purified Lin, lead and other coatings can learn from each other, play an integral anti-corrosion advantages. . Of course there are 'boring equipment, construction difficulties increase the weight of lead and other negative factors exist. Demonstrated by repeated deliberation,[link widoczny dla zalogowanych], that the system outweigh the disadvantages, technological innovation in the design of all facilities at the banquet. . Practice is the only correct design standards, is now three years later, had made five transformation of normal operation of chloral tower, life has been put off more than six times the economic benefit is substantial r, J. Through this experience to design practice, did not prepare chemical preservative did not count, in addition to looking for and information on the One ITX standards, the conditions should be further production site in particular, on the process operating acupuncture working conditions, and the actual composition of the material have a better understanding. Select anti-corrosion materials only 'solution corrosion; l0 performance is not enough, must also be other properties of the material, domestic processing capacity and quality of status quo, for a wide range of survey r ~ 『solution, if any, should be the precedent case Jie find out about, learn from experiences and lessons learned. The only way to make more accurate choices, reduce equipment corrosion design errors. 'Ho said that threat of Bo ¨ u and 93: Peel screen】 of broken rc. . -C 'lame turbid bream static ≥ i /. ,,. . (. A / J Winter Construction of glass reinforced plastic lining Social Security (state Yonghong Chemical Plant, Shanxi Yongji 0 ~ 503) / * Ring cable factory pharmaceutical plant with acidification acid chemical tank, liquid tank, the seven sets of carbon steel equipment, to be lined with glass, steel, with a total lining area of 500m.. The process parameters: working pressure: atmospheric temperature: ≤ 15 ~ (3. acidified liquid medium t Ring tpH1.7 a 1.9 cable. acidification tank Mausoleum of time per can; 2 hours for filling the filtrate tank for continuous progress of the works arrangement, lining construction in mid-March to t1. 'At that time coincided with the winter,' the outdoor temperature is below a 10 ~ C, from the Danube glass steel construction specifications construction temperature of 15-251. will return to work pieces coated core heat 3. -350 ℃ quickly in cold water,[link widoczny dla zalogowanych], so that access can be obtained, revolves around a very solid, tough, translucent coating. 2. to return to work piece is heated to 330 Tu ℃ for a period of time, then heated to about 400 ℃, heat a few hours down to room temperature, can be heat-resistant polymeric coating II suspension spraying polyphenylene sulfide at room temperature has yet to solvents. This can only resin Airport volatile scattered body (95% industrial alcohol) suspension for spraying into the towel. by spraying of pure PPS prone porous,: to ensure the quality and the price is high, so a certain amount 0 fill, fill it increases the proportion of wide-care changes, 'or even up to 25%, so you can guarantee the quality of spraying can be greatly reduced cost, usually filled with titanium n from powder, americium oxide Qiang,[link widoczny dla zalogowanych], table body spray two 【Arts: i. to 2O% Solid materials (PPS, fill) and the O alcohol (cI5 industrial alcohol) to fully mixed into a paste, can not even 8o mesh better. can be added in the mixture,, Yi 6: dagger,, phase out humidity large q:-8o% far. As the temperature is low, likely to result in incomplete curing a direct impact on the glass lining: quality, leaving the serious troubles. To overcome the disadvantages of fiberglass construction in winter,[link widoczny dla zalogowanych], to ensure the construction quality of clamor I take mine j various construction measures. ingredients used epoxy glass lined steel. Winter epoxy Chong big stick, should be heated to 6O ℃ thinning fine. custodial connected with migration cents glycol to reduce the evaporation rate of alcohol. 2, will need to Tu Fu: j pieces by the lost-wax, rust, dust processing and then into a debate Wang. spray gun material storage tank, under constant injection pressure at the spray distance 2OCm 2-5kgf/Cm about: a coating thickness of not more than 0 .05 Shan. 3 Tu Fu jv ~。--- F \cooling, the plastics parts exposed to air after cooled to room temperature. Repeat 2-5 times per lO operation to complete the coating compound. plastination when asked the last time may be extended, and then by quenching,[link widoczny dla zalogowanych], is about the last time Tu complex plastics parts immediately after quenching in water; also be re-coated after the last piece in a long time under 320 ℃ plastics, and natural cooling in air 也好. Finally, on examination, qualified to use , substandard products in need of repair before use mirage Sim p
