Iibinta kulul ee udgoonka polyether polyurethane acrylate ee alwaax, warqad iyo daahan caag ah

ZC6203 waa polyeter acrylate polyurethane ah.Polyether polyol waxaa loo soo gaabiyaa polyeter.Waa oligomer leh curaarta ether (- ror -) ee silsiladda ugu weyn iyo in ka badan laba kooxood oo hydroxyl (-OH) ee kooxda dhamaadka ama kooxda dhinaca.Waxaa lagu diyaariyaa polymerization of initiator (ka kooban oo ay ku jiraan kooxda hydrogen firfircoon) leh ethylene oxide (EO), propylene oxide (PO), epoxy butane (Bo) joogitaanka kicinta.Wax soo saarka ugu weyn ee polyeter-ka waa glycerol (glycerol) sida bilawga iyo epoxide.Noocyo kala duwan oo polyeter-ka guud ah ayaa lagu soo saaraa iyadoo la bedelayo qaabka quudinta (isku dhafan ama gooni ah), saamiga qiyaasta iyo nidaamka quudinta ee Po iyo EO.

Tilmaamaha farsamada: viscosity waa 40000-70000pa S / 25℃, Qiimaha acid <0.5 (NCO%), shaqeynta 3 (qiimaha aragtida), dareere aan midab lahayn ama huruud ah oo muuqaal ah;Alaabtani waxay leedahay faa'iidooyinka adkaanta wanaagsan, xoogga filimka sare, dhaqdhaqaaqa falcelinta sare, xannibaad adag iyo wixii la mid ah.Waxaa si weyn loo isticmaalaa khad daweynta iftiinka, alaabta alwaax, daahan sagxadda, daahan warqad, daahan caag ah, buufin vacuum, daahan biraha iyo beeraha kale.

Silsiladda ugu weyn ee zc6203 waxay ka kooban tahay dammaanad ether (- ror -), iyo kooxda dhamaadka ama kooxda dhinac ka kooban oligomers ka badan 2 kooxaha hydroxyl (- OH).Waxa la sameeyay iyadoo giraanta furitaanka polymerization of polyols miisaanka kelli hoose, polyamines ama xeryahooda ka kooban hydrogen firfircoon leh olefins oxidized hoos fal kicinta.Oxidized olefins waxay u badan yihiin propylene oxide (propylene oxide) iyo ethylene oxide (etylene oxide), oo propylene oxide ka mid ah ayaa ugu muhiimsan.Miisaanka molecular ee polyeter-ka leh hydroxyl-propylene glycol iyo tetrahydroxy-propylene glycol ee isticmaalka guud waa 4000-400.Xabagta Polyether-ka ee loo isticmaalo sida koollada waa inay ka saartaa soo-saareyaasha alkaline-ka ee hadha inta lagu jiro polymerization, sababtoo ah waxay kicin karaan kala-soocida isocyanates waxayna saameynayaan tayada xabagta.
