Thepa ea polasetiki ea ABS

Lebitso la lik'hemik'hale: Acrylonitrile-butadiene-styrene copolymer
Lebitso la Senyesemane: Acrylonitrile Butadiene Styrene
Matla a khoheli a itseng: 1.05 g/cm3 Ho fokotseha ha hlobo: 0.4-0.7%
Mocheso oa ho bopa: 200-240℃ Maemo a ho omisa: 80-90℃ lihora tse 2
Likaroloana:
1.Tshebetso e ntle ka kakaretso, matla a tshusumetso e phahameng, botsitso ba dikhemikhale, le thepa e ntle ya motlakase.
2. E na le bokgoni bo botle ba ho kopanya le plexiglass ya 372 mme e entswe ka dikarolo tsa polasetiki tse mebala e mmedi, mme bokahodimo bo ka manehwa ka chrome mme ba pentwa.
3. Ho na le khanyetso e phahameng ea tšusumetso, khanyetso e phahameng ea mocheso, e thibelang malakabe, e matlafalitsoeng, e bonaletsang le maemo a mang.
4. Ho phalla ha metsi ho mpe hanyane ho feta HIPS, ho betere ho feta PMMA, PC, jj., mme e na le ho tenyetseha ho hotle.
Tšebeliso: e loketse ho etsa likarolo tse akaretsang tsa mechini, likarolo tse fokotsang ho tsofala le tse sa tsofaleng, likarolo tsa phetiso le likarolo tsa puisano.
Litšobotsi tsa ho bopa:
1. Thepa e nang le sebopeho se se nang sebopeho, e phallang hantle, e monya mongobo o mongata, 'me e lokela ho omisoa ka botlalo. Likarolo tsa polasetiki tse hlokang ho benya holim'a metsi li lokela ho chesoa le ho omisoa nako e telele mochesong oa likhato tse 80-90 ka lihora tse 3.
2. Ho eletsoa ho nka mocheso o phahameng oa thepa le mocheso o phahameng oa hlobo, empa mocheso oa thepa o phahame haholo 'me o bonolo ho o bola (mocheso oa ho bola ke likhato tse >270). Bakeng sa likarolo tsa polasetiki tse nang le ho nepahala ho hoholo, mocheso oa hlobo e lokela ho ba likhato tse 50-60, tse hanelang ho benya haholo. Bakeng sa likarolo tsa thermoplastic, mocheso oa hlobo e lokela ho ba likhato tse 60-80.
3. Haeba o hloka ho rarolla bothata ba ho thiba metsi, o hloka ho ntlafatsa ho phalla ha thepa, ho amohela mocheso o phahameng oa thepa, mocheso o phahameng oa hlobo, kapa ho fetola boemo ba metsi le mekhoa e meng.
4. Haeba ho etsoa thepa e sa cheseng mocheso kapa e thibelang malakabe, lihlahisoa tsa polasetiki tse bolang li tla sala holim'a hlobo kamora matsatsi a 3-7 a tlhahiso, e leng se tla etsa hore karolo e ka holimo ea hlobo e benye, 'me hlobo e tlameha ho hloekisoa ka nako, 'me karolo e ka holimo ea hlobo e hloka ho eketsa boemo ba mosi.
Resin ea ABS ke polymer e nang le tlhahiso e kholo ka ho fetisisa le e sebelisoang haholo hajoale. E kopanya ka tlhaho litšobotsi tse fapaneng tsa PS, SAN le BS, 'me e na le litšobotsi tse ntle tsa mechini tsa ho tiea, ho tiea le ho tiea. ABS ke terpolymer ea acrylonitrile, butadiene le styrene. A e emetse acrylonitrile, B e emetse butadiene, 'me S e emetse styrene.
Ka kakaretso polasetiki ea boenjiniere ba ABS ha e bonahale hantle. Ponahalo ea eona e bobebe joaloka lenaka la tlou, ha e na chefo, ebile ha e na tatso. E na le litšobotsi tsa ho tiea, ho thatafala le ho tiea. E chesa butle, 'me lelakabe le mosehla ka mosi o motšo. Kamora ho chesa, polasetiki ea nolofala 'me ea cha ebe e ntša monko o ikhethang oa sinamone, empa ha ho na ketsahalo e qhibilihang le e rothang.
Lipolasitiki tsa boenjiniere ba ABS li na le thepa e ntle e akaretsang, matla a maholo a tšusumetso, botsitso bo botle ba litekanyo, thepa ea motlakase, ho hanyetsa ho khohlela, ho hanyetsa lik'hemik'hale, ho daea habonolo, le ts'ebetso e ntle ea ho bopa le ts'ebetso ea mechini. Resin ea ABS e hanela metsi, matsoai a sa tloaelehang, alkali le li-acid. Ha e qhibilihe ho li-alcohol tse ngata le li-hydrocarbon solvents, empa e qhibiliha habonolo ho aldehydes, ketones, esters le li-hydrocarbon tse ling tse nang le chlorine.
Mathata a polasetiki ea boenjiniere ea ABS: mocheso o tlase oa ho sotha mocheso, ho tuka habonolo, le ho hanyetsa boemo ba leholimo hampe.
