PVA
Jumla PVA Polyvinyl Barasa
Bayanin samfur
Polyvinyl barasa (PVA) polymer ne mai narkewa da ruwa wanda yawanci fari ne a cikin flake, flocculent, ko foda.
Na biyu, halayen samfur
Kyakkyawan solubility na ruwa: yana iya narke cikin ruwa a yanayin zafi daban-daban don samar da bayani na gaskiya.
Kyakkyawan mannewa: yana da tasirin ha?in gwiwa mai ?arfi akan nau'ikan kayan.
Kyakkyawan tsarin fim: Fim ?in da aka kafa yana da ?arfin ?arfi da sassauci.
Juriya mai narkewa: Zuwa wani ?an lokaci, yana iya tsayayya da zaizayar abubuwan kaushi na gama gari.
Biocompatibility: Dan kadan mara guba da abokantaka ga jikin mutum da muhalli.
amfani da samfur
Masana'antar Yadi
An yi amfani da shi azaman kayan ?ima don ha?aka ?arfi da sa juriya na yadudduka.
Bugawa da rini auxiliaries, taimaka rini adhesion da uniform rarraba.
Masana'antar takarda
Wakilin sizing na takarda don ?ara ?arfi da juriya na ruwa na takarda.
Manne launi mai launi don inganta kaddarorin takarda mai rufi.
Filin m
M don itace, takarda, fiber da sauran kayan.
Masana'antar gine-gine
Ciminti Additives don inganta kaddarorin siminti.
Filin likitanci
Kayan albarkatun kasa na capsule na miyagun ?wayoyi, kayan taimako na maganin ophthalmic.
Tsarin samarwa
An shirya shi gaba?aya ta hanyar alcoholysis na polyvinyl acetate.
Hasashen kasuwa
Tare da karuwar bu?atar kayan aiki mai girma a cikin masana'antu daban-daban, tsammanin kasuwa na PVA yana da fa?i. Sakamakon ha?aka masana'antu na gargajiya kamar su yadi da yin takarda, da kuma ha?aka fannonin da ke tasowa kamar su biomedicine da kayan lantarki, ana sa ran kasuwar ta za ta ci gaba da ha?aka.
yi amfani da matakan kariya
Kauce wa danshi da yanayin zafi lokacin adanawa.
Lokacin narkar da, zafin jiki da saurin motsawa ya kamata a sarrafa shi don tabbatar da isasshen narkewa kuma aikin ba ya tasiri.
Za?i samfuran da suka dace da ?ayyadaddun bayanai bisa ga bu?atun aikace-aikace daban-daban.
Alal misali, a cikin masana'antun masana'antu, PVA tare da takamaiman danko da digiri na alcoholysis yana bu?atar za?ar bisa ga bu?atun kayan aiki da tsari na yarn; A cikin aikace-aikacen adhesives, tsari da amfani da PVA ya kamata a daidaita su bisa ga yanayin manne.
Don ta?aitawa, Polyvinyl barasa yana taka muhimmiyar rawa a fannoni da yawa tare da kaddarorinsa na musamman, yana ba da tallafi mai ?arfi don ha?aka masana'antu masu ala?a.
