Polyacrylonitrile/PAN/CAS:25014-41-9

Tlhaloso:

Polyacrylonitrile ke mofuta oa resin ea maiketsetso e hlahisoang ka polymerization ea acrylonitrile ea free radical. Ke ea lelapa la resin ea acrylic. Ke thermoplastic, 'me e hanela li-solvent le lik'hemik'hale tse ngata ka lebaka la litlamo tse matla tsa lik'hemik'hale tse thehiloeng lipakeng tsa lihlopha tsa nitrile. Ke mofuta oa polymer e feto-fetohang e ka sebelisoang ho hlahisa mefuta e mengata ea lihlahisoa tse kang likhoele tsa masela, lera la ho sefa ka ho fetisisa, faeba ea carbon le likhoele tse se nang letho bakeng sa reverse osmosis. Homopolymer ea eona e ka boela ea sebelisoa e le likhoele ka har'a awning ea kantle, liseile tsa likepe, le konkreite e matlafalitsoeng ka fiber. E ka boela ea sebelisoa bakeng sa tlhahiso ea masela a hanyetsang malakabe ka tlhaho (FR).

Ka lebaka la thepa ea eona e ikhethang joalo ka botsitso khahlanong le ho senyeha ha UV, ho ba le bongata bo tlase, matla a phahameng le modulus ea ho tenyetseha, botsitso ba mocheso, ho se thekesele le ho hanyetsa lik'hemik'hale, Polyacrylonitrile ke polymer ea bohlokoa bakeng sa mefuta e mengata ea lits'ebetso. Kahoo, e sebelisoa lits'ebetsong tsa masela ka lebaka la litšobotsi tsa eona tse kang boea, ho etseng faeba ea carbon, lera la ho sefa, likhoele bakeng sa ho matlafatsa samente, liseile bakeng sa likepe, masela a awning lits'ebetsong tsa kantle, likhoele tse ikhethang bakeng sa ho kenya mocheso le ho futhumatsa, likhoele tse thibelang malakabe le tlhahisong ea li-felt bakeng sa litsamaiso tsa ho sefa moea o chesang.
Li-copolymer tse nang le polyacrylonitrile, tse thibelang malakabe, li sebelisoa e le likhoele ho etsa liaparo tse lohiloeng, joalo ka likausi le lijesi, hammoho le litente tse kang lihlahisoa tsa kantle. Poly(acrylonitrile-co-butadiene-co--styrene)(ABS) le Poly(styrene-co-acrylonitrile)(SAN) li sebelisoa e le polasetiki. ABS ke polymer e bobebe ebile e matla haholo. E bobebe ebile e matla ho lekana ho sebelisoa tlhahisong ea likarolo tsa 'mele oa koloi. Kahoo, thepa ena e etsa hore likoloi li be bobebe ka ho sebelisa mafura a fokolang 'me kahoo li silafatsa hanyane.
Matla a ABS a tsoa lihlopheng tsa nitrile tse teng liyuniting tsa eona tsa acrylonitrile. Lihlopha tsa nitrile li polar haholo; ka hona, li ka hoheloa. Ketsahalo ena e lumella litefiso tse fapaneng lihlopheng tsa nitrile ho tsitsisa tse ling. Khoheli ena e matla e tšoara liketane tsa ABS ka thata haholo, kahoo, e etsa hore thepa e be matla haholo. Ho feta moo, polybutadiene ea rabara e teng ho eona e etsa hore ABS e be polymer e thata.
