UMLIMI: SINOPEC

PVA iye iipropati ezininzi ezingaqhelekanga ezifana ukunyibilika namanzi, impahla ifayibha-ukwakha, adhesiveness, ipropati bhanya-ukwakha, uzinzo emulsion, uzinzo eziziintsali, ukumelana ioli, acid, kwaye kwealkali, imichiza reactivity, biodegradability, kwakunye meltability (okanye thermoplasticity) kunye neempawu ezininzi ezizodwa nezikhethekileyo nge modification.PVA sisetyenziswa ngokubanzi kumashishini ezininzi ezifana nemiqhaphu, iphepha, ulwakhiwo, amachiza, ushicilelo, ukupakishwa, namayeza afanelekileyo, iisepha & izithambiso, ezolimo, iiseramikhi, intsimbi & intsimbi, elektroniki, electrolysis, electroplating, kwaye njl

PVA, leyo egqwesileyo ukhuselo colloid kwaye umsebenzi ngaphezulu kunabanye, isoloko isetyenziswa kwiintsali somfanekiso kukunqunyanyiswa polymerization of IVinyl chloride monomer (VCM). Ukusebenza kwe PVC intlaka na ubuhle kakhulu ngokukhetha i PVA grade abafanelekileyo degree eyiyo polymerization kunye haydrolisis.

PVA ukuba Isetyenziswa ngokubanzi colloid okubakhusela okanye thickener ukuba emulsion polymerization of IVinyl acetate (VAc) okanye VAc / acrylate. neneempawu zilandelayo: adhesiveness elihle; ukwanda lokuqala oku- futhi omisa iqondo lo gama lisetyenziswa kunye lokufaka; ukumelana elihle oiloutstanding amandla ukrobiso enyamezele kunye nokusebenza izinzile.

izicelo ezimbini ezibalulekileyo PVA kukuba kusetyenziswa vinylon feedstock kunye nearhente solinganiso for textile.As izinto okwenziwa vinylon ifayibha, na iingenelo yokuba ophezulu ngamandla, ukufuma edalwayo, ukumelana lingonakali, ukumelana kwelanga, nokumelana namhlophe ngebala. Kananjalo kufuneka basonta umqhaphu, uboya kunye viscose ifayibha okanye basonta kuphela kunye itself.As solinganiso arhente nemiqhaphu, Oko akuyi ezinokudla okanye kugxagxiseka kunye adhesion ezilungileyo umqhaphu, hemp, ipholiyesta kunye viscose nefayibha.

PVA unako ukuvelisa amanzi enyibilikayo bhanyabhanya kunye namanzi-ukuxhathisa film. PVA ifumaneka iimveliso benziwa le nto ikwaveza omnye iimpawu ezingundoqo PVA, oko kukuthi, eqine aphezulu amandla, ukumelana ibinyityilikiswa eziphilayo kunye tightness.They emoyeni zombini ngokubanzi esetyenziswa kwishishini package na, hayi kuphela elukiweyo, kodwa ngenxa amachiza, ukutya, iikhemikhali ngemihla, amachiza ezolimo, dyestuff, kanye nokunye

PVA ifumene ukusetyenziswa liphela ukunyanga kumphezulu yephepha njengoko liye adhesiveness ezibalaseleyo kunye dispersibility kwaye akuyi kuchaphazela impahla kwezinye yokuhlanganisa ezisetyenziswa zidityaniswe. Izinto eziluncedo ze PVA usebenzisa: Surface amandla (printability); Mandla kunye Z-axis (paper amandla lwangaphakathi); ukumelana Ukusonga; ukumelana Abrasive; Ukuphuculwa ngobuqhophololo; Ukuphucula umgangatho glossiness; Ndikhule kwentshukumo oyile kunye nesinyibilikisi (ipropati umqobo).
