I-Polyacrylonitrile/PAN/CAS:25014-41-9

Incazelo:

I-Polyacrylonitrile uhlobo lwe-resin yokwenziwa ekhiqizwa nge-free radical polymerization ye-acrylonitrile. Ingowomndeni we-acrylic resin. I-thermoplastic, futhi imelana nezinyibilikisi eziningi namakhemikhali ngenxa yezibopho zamakhemikhali eziqinile ezakhiwe phakathi kwamaqembu e-nitrile. Iwuhlobo lwe-polymer eguquguqukayo engasetshenziswa ukukhiqiza izinhlobo eziningi zemikhiqizo efana nemicu yezindwangu, i-ultra filtration membrane, i-carbon fiber kanye nemicu engenalutho ye-reverse osmosis. I-homopolymer yayo ingasetshenziswa futhi njengemicu e-awning yangaphandle, amaseyili ezikebheni, kanye nokhonkolo oluqiniswe nge-fiber. Ingasetshenziswa futhi ekukhiqizeni izindwangu ezingamelani nomlilo (FR).

Imininingwane

Ukusetshenziswa

Ngenxa yezakhiwo zayo ezikhethekile ezifana nokuqina kokuwohloka kwe-UV, ukuminyana okuphansi, amandla aphezulu kanye ne-modulus yokunwebeka, ukuqina kokushisa, ukungaguquguquki kanye nokumelana namakhemikhali, i-Polyacrylonitrile iyi-polymer ebalulekile yezinhlelo eziningi zokusebenza. Ngakho-ke, isetshenziswa ezinhlotsheni ngenxa yezici zayo ezifana noboya, ekwenzeni i-carbon fiber, ulwelwesi lokuhlunga, imicu yokuqinisa usimende, amaseyili ezikebheni, izindwangu zokulenga ezindlini zokusebenza zangaphandle, imicu ekhethekile yokuvikela i-acoustic kanye nokushisa, imicu yokulwa nomlilo kanye nokukhiqizwa kwama-felts ezinhlelo zokuhlunga umoya oshisayo.
Ama-copolymer aqukethe i-polyacrylonitrile, avimbela ilangabi, asetshenziswa njengezintambo ukwenza izingubo ezilukiwe, njengamasokisi nama-sweaters, kanye nemikhiqizo yangaphandle efana namatende. I-Poly(acrylonitrile-co-butadiene-co--styrene)(ABS) kanye ne-Poly(styrene-co-acrylonitrile)(SAN) zisetshenziswa njengepulasitiki. I-ABS iyi-polymer elula futhi enamandla kakhulu. Ilula futhi inamandla ngokwanele ukuthi ingasetshenziswa ekukhiqizeni izingxenye zomzimba wemoto. Ngakho-ke, le nto yenza izimoto zibe lula zisebenzisa uphethiloli omncane futhi ngaleyo ndlela zingcolise kancane.
Amandla e-ABS avela emaqenjini e-nitrile akhona kumayunithi ayo e-acrylonitrile. Amaqembu e-nitrile aphansi kakhulu; ngakho-ke, angakhangwa omunye nomunye. Lokhu kwenzeka kuvumela amacala aphikisanayo emaqenjini e-nitrile ukuthi azinze omunye komunye. Lokhu kukhanga okunamandla kugcina amaketanga e-ABS ngokuqinile, ngakho-ke, kwenza izinto zibe namandla kakhulu. Ngaphezu kwalokho, i-polybutadiene yerabha ekhona kuyo yenza i-ABS ibe yi-polymer eqinile.
