Maxaa la beddelay Polyethylene?
Maxaa la beddelay Polyethylene?
Noocyada la beddelay ee polyetylenka waxaa ka mid ah polyetylen koloriin leh, koloroosulfonated polyetylen, polyetylen iskutallaab ah iyo noocyo la isku daray oo la beddelay.
Polyethylene koloriin leh:
Koloriin random ah oo la helay iyadoo qayb ahaan lagu beddelay atamka hydrogen ee polyetylen leh koloriin. Chlorination waxaa lagu fuliyaa iyadoo la bilaabayo iftiinka ama peroxide, waxaana inta badan soo saara habka joojinta biyaha ee warshadaha. Farqiga u dhexeeya miisaanka kellika iyo qaybinta awgeed, darajada qaybinta, shahaado koloriin ka dib koloriin, qaybinta atomka koloriinta iyo crystallinity haraaga polyetylen cayriin, koloriin leh polyetylen laga bilaabo caag ilaa caag adag ayaa la heli karaa. Isticmaalka ugu weyn waa sida wax ka beddelka chloride polyvinyl si loo hagaajiyo iska caabbinta polyvinyl chloride. Polyethylene koloriin laftiisa ayaa sidoo kale loo isticmaali karaa sida walxaha dahaarka korontada iyo walxaha dhulka.
Polyethylene chlorosulfonated:
Marka polyetylenku uu la falgalo koloriin ka kooban sulfur dioxide, qayb ka mid ah atamka hydrogen ee ku jira molecule waxaa lagu badalaa koloriin iyo qadar yar oo ah kooxaha chloride sulfonyl si loo helo polyetylen chlorosulfonated. Habka ugu muhiimsan ee warshaduhu waa habka joojinta. Chlorosulfonated polyethylene waxay u adkaysataa ozone, daxalka kiimikaad, saliidda, kulaylka, iftiinka, xoqidda iyo xoogga xajinta. Waa elastomer leh sifooyin dhammaystiran oo wanaagsan waxaana loo isticmaali karaa in lagu sameeyo qaybo qalabka la xidhiidha cuntada.
XLPE:
Isticmaalka habka shucaaca (X-ray, beam electron ama ultraviolet irradiation, iwm.) ama habka kiimikada (peroxide ama silikoon iskutallaabta) si aad polyetylen toosan uga dhigto shabakad ama polyetylen iskutallaab ah oo bulk ah. Waxaa ka mid ah, habka isku-xiran ee silikoonku wuxuu leeyahay nidaam fudud, kharash yar oo hawlgal ah, naqshadeynta iyo isku-dhafka ayaa lagu fulin karaa tillaabooyin, sidaas darteed dharbaaxada dharbaaxada iyo dhejinta duritaanka ayaa ku habboon. Iska caabbinta kulaylka, iska caabbinta cadaadiska deegaanka iyo sifooyinka farsamada ee polyetylen-ku-xiran ayaa si weyn loo wanaajiyey marka la barbardhigo polyetylen, waxayna ku habboon tahay tuubooyinka waaweyn, fiilooyinka iyo fiilooyinka, iyo alaabta rotomolding.
Wax ka beddelka polyetylen:
Ka dib marka la isku daro polyetylen cufnaanta tooska ah iyo cufnaanta hoose ee polyetylen, waxaa loo isticmaali karaa in lagu farsameeyo filimada iyo alaabta kale, iyo wax qabadku wuxuu ka fiican yahay cufnaanta hoose ee polyetylen. Polyethylene iyo caag ethylene propylene ayaa la isku dari karaa si ay u soo saaraan tiro balaadhan oo ah kuleylka Elastomers
