Polyacrylonitrile/PAN/CAS:25014-41-9

Kev piav qhia:

Polyacrylonitrile yog ib hom tshuaj yas uas tsim los ntawm kev sib xyaw ua ke ntawm cov dawb radical polymerization ntawm acrylonitrile. Nws yog ib hom acrylic resin tsev neeg. Nws yog thermoplastic, thiab tiv taus feem ntau cov kuab tshuaj thiab tshuaj vim muaj cov tshuaj sib txuas ua ke ntawm cov pab pawg nitrile. Nws yog ib hom polymer uas siv tau ntau yam uas siv tau los tsim ntau yam khoom xws li cov fibers rau textiles, ultra filtration membrane, carbon fiber thiab hollow fibers rau reverse osmosis. Nws homopolymer kuj siv tau ua cov fibers hauv awning sab nraum zoov, sails rau yachts, thiab fiber-reinforced concrete. Nws kuj siv tau rau kev tsim cov ntaub uas tiv taus hluav taws (FR).

Cov Lus Qhia Tshwj Xeeb

Kev Siv

Vim nws cov khoom tshwj xeeb xws li kev ruaj khov rau UV degradation, qis qis, lub zog siab thiab modulus ntawm elasticity, thermal stability, tsis-fusibility thiab tshuaj lom neeg tsis kam, Polyacrylonitrile yog ib qho tseem ceeb polymer rau ntau yam kev siv. Yog li, nws yog siv rau hauv cov ntawv thov textile vim nws cov yam ntxwv zoo li wool, hauv kev ua cov carbon fiber, lim dej, fibers rau cement reinforcement, sails rau yachts, awning ntaub hauv kev siv sab nraum zoov, cov fibers tshwj xeeb rau acoustic thiab thermal rwb thaiv tsev, anti-flame fibers thiab hauv kev tsim cov felts rau cov cua kub lim dej.
Cov copolymers uas muaj polyacrylonitrile, uas yog cov hluav taws kub-retardant, yog siv ua cov fibers los ua cov khaub ncaws knitted, zoo li thom khwm thiab sweaters, nrog rau cov khoom sab nraum zoov xws li cov tsev pheeb suab. Poly(acrylonitrile-co-butadiene-co--styrene)(ABS) thiab Poly(styrene-co-acrylonitrile)(SAN) yog siv ua yas. ABS yog ib qho polymer sib dua thiab muaj zog heev. Nws sib dua thiab muaj zog txaus siv rau hauv kev tsim cov khoom siv hauv lub cev tsheb. Yog li, cov khoom siv no ua rau cov tsheb sib dua siv roj tsawg dua thiab ua rau muaj kuab paug tsawg dua.
Lub zog ntawm ABS yog los ntawm cov pawg nitrile uas muaj nyob rau hauv nws cov acrylonitrile units. Cov pawg nitrile yog polar heev; yog li ntawd, lawv tuaj yeem rub rau ib leeg. Qhov tshwm sim no tso cai rau cov nqi sib txawv ntawm cov pawg nitrile kom ruaj khov ib leeg. Qhov kev rub muaj zog no tuav ABS saw hlau nruj heev, yog li, nws ua rau cov khoom siv muaj zog heev. Ntxiv mus, cov roj hmab polybutadiene uas muaj nyob hauv nws ua rau ABS yog cov polymer tawv.
