Inkcazo:
I-Polyacrylonitrile luhlobo lwe-resin yokwenziwa eyenziwe nge-free radical polymerization ye-acrylonitrile. Ikwintsapho ye-acrylic resin. Yi-thermoplastic, kwaye iyamelana nezinyibilikisi ezininzi kunye neekhemikhali ngenxa yezibopho ezinamandla zeekhemikhali ezenziwe phakathi kwamaqela e-nitrile. Luhlobo lwe-polymer eguquguqukayo enokusetyenziswa ukuvelisa iintlobo ezininzi zeemveliso ezifana neefayibha zelaphu, i-ultra filtration membrane, i-carbon fiber kunye neefayibha ezingenanto ze-reverse osmosis. I-homopolymer yayo ingasetyenziswa njengefayibha kwi-awning yangaphandle, iiseyile zeenqanawa, kunye nekhonkrithi eqiniswe ngefayibha. Ingasetyenziselwa ukuvelisa amalaphu amelana nomlilo (FR).

Ukusetyenziswa
Ngenxa yeempawu zayo ezikhethekileyo ezifana nokuzinza ekuwohlokeni kwe-UV, uxinano oluphantsi, amandla aphezulu kunye ne-modulus yokuthamba, ukuzinza kobushushu, ukungaguquguquki kunye nokumelana neekhemikhali, iPolyacrylonitrile yipolymer ebalulekileyo kwiintlobo ngeentlobo zezicelo. Ke ngoko, isetyenziswa kwizicelo zelaphu ngenxa yeempawu zayo ezifana noboya, ekwenzeni i-carbon fiber, ii-filtrate membranes, iifayibha zokuqinisa isamente, iiseyile zeenqanawa, amalaphu e-awning kwizicelo zangaphandle, iifayibha ezikhethekileyo ze-acoustic kunye ne-thermal insulation, iifayibha ezichasene nelangatye kunye nemveliso yeefelts zeenkqubo zokucoca umoya oshushu.
IiCopolymers eziqulethe i-polyacrylonitrile, ezingatshisi ilangabi, zisetyenziswa njengeefayibha ukwenza iimpahla ezilukiweyo, njengeekawusi kunye neesweta, kunye neemveliso zangaphandle ezifana neetente. I-Poly(acrylonitrile-co-butadiene-co--styrene)(ABS) kunye ne-Poly(styrene-co-acrylonitrile)(SAN) zisetyenziswa njengeplastiki. I-ABS yipolymer ekhaphukhaphu kwaye inamandla kakhulu. Ikhaphukhaphu kwaye yomelele ngokwaneleyo ukuba isetyenziswe ekuveliseni amalungu omzimba wemoto. Ke ngoko, le nto yenza iimoto zibe lula xa zisebenzisa amafutha amancinci kwaye ngaloo ndlela zingcolise kancinci.
Amandla e-ABS avela kumaqela e-nitrile akhoyo kwiiyunithi zayo ze-acrylonitrile. Amaqela e-nitrile anombala ophantsi kakhulu; ngoko ke, anokutsaleleka omnye komnye. Oku kwenzeka kuvumela ukuba amaqela e-nitrile aphikisane. Olu phawu lunamandla lubamba imixokelelwane ye-ABS ngokuqinileyo, ngoko ke, lwenza ukuba izinto zibe namandla kakhulu. Ngaphezu koko, i-polybutadiene yerabha ekhoyo kuyo yenza i-ABS ibe yi-polymer eqinileyo.

25KG/ibhegi okanye ngokweemfuno zabathengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
