chloroprene caag CR244
Neoprene, sidoo kale loo yaqaan caag chloroprene iyo caag Xinping. Caag synthetic ah oo ay soo saartay α-polymerization of chloroprene (2-chloro-1,3- butadiene) ayaa si weyn loogu isticmaalaa alaabada cimilada, calaacalaha viscose, dahaarka iyo shidaalka gantaalada.
Dufanka ama block leh muuqaal caano leh oo caddaan, beige ama bunni khafiif ah waa elastomer ay soo saartay alfa polymerization of chloroprene (ie 2- chloro -1,3- butadiene) oo ah alaabta ceeriin ee ugu weyn. Halbeegga milanka ee caagga chloroprene wuxuu xisaabiyaa δ = 9.2 ~ 9.41. Ku milma toluene, xylene, dichloroethane iyo vanadium ethylene, wax yar ku milma acetone, methyl ethyl ketone, ethyl acetate iyo cyclohexane, oo aan milmin karin n-hexane iyo gaaska dareeraha, laakiin ku milma dareeraha isku dhafan ee ka kooban dareeraha wanaagsan iyo dareeraha xun iyo kuwa aan milmin. ama dareere xun oo aan milmayn saamiga saxda ah, bararka saliidda khudradda iyo saliidda macdanta laakiin aan milmin.
Guryaha jireed ee wanaagsan iyo farsamada, caabbinta saliidda, caabbinta kulaylka, caabbinta ololka, caabbinta iftiinka qorraxda, caabbinta ozone, caabbinta acid iyo alkali iyo caabbinta kiimikada. Khasaarooyinku waa iska caabin qabow oo liita iyo xasilloonida kaydinta. Waxa ay leedahay xoog xajin sare, elongation, crystallinity rogi kara iyo adhesion wanaagsan. Iska caabinta gabowga iyo caabbinta kulaylka. Iska caabin saliid heer sare ah iyo caabbinta daxalka kiimikada. Iska caabinta cimilada iyo iska caabbinta gabowga ozone ayaa ah ka labaad kaliya caagga ethylene propylene iyo caagga butyl. Iska caabbinta kulaylku waxay u dhigantaa kan caag nitrile ah, oo leh heerkul daal oo ah 230 ~ 260 ℃, iska caabbinta muddada gaaban ee 120 ~ 150 ℃, isticmaalka muddada dheer ee 80 ~ 100 ℃, iyo dib u dhacyada ololka qaarkood. Iska caabbinta saliidda ayaa ah ka labaad oo keliya caag nitrile ah. Iska caabbinta daxalka wanaagsan ee inorganic acid iyo alkali. Iska caabin qabow oo liita iyo dahaarka koronto oo liita. Xasiloonida kaydinta caag cayriin ah ayaa liidata, taas oo keenta ifafaale "is-sulfur". Viscosity Mooney wuu kordhaa oo caagga ceeriin wuu adkaadaa. Noocyada ajnabiga ah waxaa ka mid ah AD-30 (USA), A-90 (Japan), 320 (Jarmalka) iyo MA40S (France).
CR122 chloroprene caag ah: alaabada caagga ah sida suumanka gudbinta, suumanka gaadiidka, fiilooyinka iyo fiilooyinka, xaashida caagga ah ee saliidda u adkaysta, tuubooyinka caagga ah ee saliidda u adkaysta iyo alaabta wax lagu xidho.
