The application of vinyl resin


1, fiberglass and liner
Vinyl resin  commonly used in a high temperature requirements , strong corrosion conditions FRP products , such as the production of large fiberglass storage tanks, tankers , towers , pipes , fans and so on. To be anti- corrosion steel container , concrete ducts are also commonly used to make Vinyl  resin fiberglass liner .
    Large chemical fertilizer urea granulation tower wall in the mid-1960s anti-corrosion coatings , urea crystallization on the concrete wall corrosion is very serious. 1969 Sichuan Luzhou Natural Gas Chemical Plant took the lead with epoxy fiberglass liner corrosion success. But epoxy resin viscosity, construction inconvenience , in recent years has begun to replace the epoxy Vinyl  resin used for urea granulation tower wall corrosion
Since Vinyl  resin has good strength, corrosion resistance and temperature resistance , and thus it can be used to make gel coat resin , used as artificial agate , marble, sanitary ware and other high-end products gelcoat . Vinyl resins to improve thixotropy and viscosity , can be added fumed carbon , together with a small amount of polar additives such as glycerol , BYK605 and so on.
2 , resin cements , mortars
   A Vinyl  resin prepared mortar , mortar for corrosion resistant lining brick panels , paving , pointing , but also corrosion-resistant resin mortar for the whole ground. Such as Beijing Chemical Plant Engineering chlor alkali evaporation surface , the medium is sodium hydroxide, 30% concentration , the use of Vinyl  resin mortar to do the whole floor , China's peaceful construction companies and other construction units on how to reduce the shrinkage of resin mortar summarizes certain aspects experience
3 , the coating
 1) light-cured coatings
Vinyl  resin with benzoquinone, benzoin ethers such as the presence of a photoinitiator , by ultraviolet radiation , can lead to crosslinking and curing extremely fast, in seconds . This feature is made use of light- curable vinyl coating save energy , greatly improving production efficiency and has a good prospect
2) flake paint
   With a Vinyl  resin and glass flake , etc. made of flake paint , can be used for equipment lined steel containers are widely used in petrochemical, metallurgy , papermaking , electroplating , chlor-alkali , medicine, food , construction and other industries, such as power plants water supply system of the desulfurization tower , sodium hydroxide , hydrochloric acid tank, etc. , exhaust system FGD precipitator , absorber , oxidation tower ; duct, chimney wall corrosion in high temperature and strength requirements of the occasion , often using flake paint and fiberglass composite structure.
