Acrylonitrile Bakeng sa Synthetic Resin

Acrylonitrile, e nang le foromo ea lik'hemik'hale C3H3N, ke motsoako oa mefuta-futa oa lintho tse phelang o fumanang sebaka sa oona liindastering tse ngata. Mokelikeli ona o se nang ’mala o ka ’na oa e-ba le monko o hlabang ’me o chesa haholo. Mouoane oa eona le moea oa eona li ka ba tsa etsa metsoako e phatlohang, kahoo e tlameha ho sebetsoa ka hloko. Leha ho le joalo, thepa ea eona e ikhethang le lisebelisoa li etsa hore e be motsoako oa bohlokoa ha ho etsoa lihlahisoa tse sa tšoaneng.

Tšebeliso

E 'ngoe ea litšebeliso tse ka sehloohong tsa acrylonitrile ke tlhahiso ea polyacrylonitrile, polymer e nang le mefuta e mengata e nang le botsitso bo botle ba mocheso le khanyetso ea lik'hemik'hale. Polymer ena e sebelisoa haholo indastering ea masela ho etsa liaparo le masela a sebetsang hantle a ka mamellang maemo a thata a tikoloho. Ho phaella moo, acrylonitrile ke mohaho oa bohlokoa oa ho haha ​​​​ha ho etsoa rabara ea nitrile, e tsejoang ka ho hanyetsa oli le lik'hemik'hale tse ntle haholo. Sena se etsa hore e be khetho e tsebahalang bakeng sa tlhahiso ea liatlana, litiiso le likhasete tse sebelisoang indastering ea likoloi, tlhokomelo ea bophelo bo botle le peterole.

Acrylonitrile e boetse e phetha karolo ea bohlokoa tlhahisong ea lidae le li-resin tsa maiketsetso. Sebopeho sa eona sa lik'hemik'hale se ka sebelisoa ho etsa lidae tse matla le tse tšoarellang nako e telele bakeng sa lisebelisoa ho tloha ho masela ho isa ho li-inks tsa khatiso. Ho feta moo, ts'ebeliso ea eona ho li-resin tsa maiketsetso e thusa ho nts'etsapele lisebelisoa tse tšoarellang le tse bobebe bakeng sa kaho, thepa ea ka tlung le indastering ea likoloi. Litšobotsi tsena li etsa hore acrylonitrile e be motsoako oa bohlokoa bakeng sa ho etsa lihlahisoa tse hlokang matla le botle bo botle.

Ntle le lits'ebetso tsa eona tsa tlhahiso, acrylonitrile e boetse e sebelisoa indastering ea meriana. Ke mohaho oa mefuta e fapaneng ea meriana, ho akarelletsa le lithibela-mafu, li-antihistamine le lithethefatsi tsa kankere. Bokhoni ba eona ba ho itšoara ka metsoako e meng bo lumella ho kopana ha limolek'hule tse rarahaneng tse nang le thepa ea phekolo. Sena se totobatsa bohlokoa ba acrylonitrile lefapheng la bongaka, ho thusa ho nts'etsopele ea lithethefatsi tse pholosang bophelo.

Qetellong, acrylonitrile ke motsoako oa bohlokoa o fetotseng liindasteri tse sa tšoaneng. Ho sa tsotellehe ho chesa ha eona le likotsi tse ka 'nang tsa e-ba teng, tšebeliso ea eona ha ho etsoa polyacrylonitrile, rabara ea nitrile, lidae, li-resin tsa maiketsetso le meriana e etsa hore e be karolo ea bohlokoa ea tlhahiso ea morao-rao. Ho sa tsotellehe hore na ho etsa masela a sebetsang hantle haholo, li-synthetics tse tšoarellang kapa meriana e pholosang bophelo, acrylonitrile e phetha karolo ea bohlokoa ho bōpa lefatše leo re phelang ho lona kajeno.
