در حال حاضر، خط اکستروژن ورق پت تهویهشده بدون خشککن دوقلو که توسط Suzhou Jwell راهاندازی شده است.، میتواند تکههایی را با حداکثر محتوای آب اولیه ppm پردازش کند. علاوه بر این، افت ویسکوزیته در داخل . دسی لیتر بر گرم کنترل می شود.
Like other manmade fibers, polyester fibers are produced using industrial methods. Thanks to their characteristics they are good substitutes for such natural fibers as cotton. They are produced by combining dimethyl terephthalate, monoethylene glycol or terephthalic acid (substitute for the dimethyl terephthalate raw materials) in the presence of good catalysts. Titanium dioxide is used to produce a semi-dull product. Also, in the production process prior to packaging, the fibers are submerged in finish (.%). For such physical characteristics as the diameter and fineness of filaments, polyester yarn production and supply is customized. The chief application of texturized polyester yarn is filament-weft or circular yarns. The advantages of polyester yarn are:
PET-GF Engineering Composite with a high molecular weight has a wide-ranging engineering application. As PET is reinforced with glass fiber, its mechanical, electrical, thermal and chemical properties as well as environmental, tolerance, creep, thermal expansion coefficient (like aluminum and brass) and, to a very large extent, extrusion capability improve. As the proportion of glass fiber and the production method (used in the production of extrusion parts and heat-deformable plates) vary, it has a wide range of applications. Among other things, it can be used in the production of household and automobile equipment requiring a high shock absorption structure, construction elements, case coating for such equipment as printers, copiers, cartridges, agricultural equipment including mowing machines, tractor engine cover, automotive spares, material transportation facilities such as palettes, crating, household equipment such as furniture as well as electrical and electronic equipment. Thanks to its very good dielectric properties, high thermal resistance and self-extinguishing characteristics, it is being increasing used in electrical, electronic, high temperature, spark-generation environments and direct-heat applications. Among other things, reference can be made to lamp-holders, cases and electrical sockets. Polynite is produced from polyester polymer compound combined with special-purpose glass fibers and other additives supplied in two versions: extrusion and compressive. The physical and chemical characteristics measured for the product are draw, bend, impact, pressure, MFI-IV and proportion of glass fibers.
Consistent with SNIA technology, the production process for this product starting with the mixing of monomers as feedstock input to the reactors for polymer solution in Dimethylformamide (DMF) in the Chemical Area through to fiber production, drawing, finishing and packaging is continuous at that each stage, samplings and controls are conducted and finally the product is graded and released in accordance with the test results.
