Mona ke setsi sa litaba sa indasteri ea ho etsa ente ea Baiyear.Ka mor'a moo, Baiyear e tla arola mokhoa oa ho bōpa ente ka lihlooho tse 'maloa ho hlahisa tlhahlobo ea lisebelisoa tse tala tsa mokhoa oa ho bopa ente, hobane ho na le litaba tse ngata haholo.Se latelang ke sehlooho sa bobeli.
(3).SA (SAN-styrene-acrylonitrile copolymer/Dali glue)
1. Ts'ebetso ea SA:
Chemical and Physical Properties: SA ke thepa e thata, e bonaletsang e sa hlaselehang habonolo ka har'a khatello ea maikutlo.Ponaletso e phahameng, mocheso oa eona o nolofatsang le matla a tšusumetso a phahame ho feta PS.Karolo ea styrene e etsa hore SA e be thata, e pepenene ebile e le bonolo ho e sebetsa;karolo ea acrylonitrile e etsa hore SA lik'hemik'hale le mocheso o tsitsitseng.SA e na le matla a ho jara moroalo, k'hemik'hale ea ho hanyetsa lik'hemik'hale, ho hanyetsa mocheso oa mocheso le botsitso ba geometri.
Ho eketsa likhalase tsa fiber fiber ho SA ho ka eketsa matla le ho hanyetsa mocheso oa mocheso, le ho fokotsa coefficient ea ho atolosa mocheso.Thempereichara ea Vicat ea SA e ka ba 110°C.Mocheso oa ho kheloha tlas'a mojaro o ka ba 100C, 'me ho fokotseha ha SA ho ka ba 0.3 ~ 0.7%.
2. Litšobotsi tsa ts'ebetso ea SA:
Mocheso oa ho sebetsa oa SA ka kakaretso ke 200-250 °C.Thepa e bonolo ho monya mongobo mme e hloka ho omisoa nako e fetang hora pele e sebetsa.Mokelikeli oa eona o mpe hanyenyane ho feta oa PS, kahoo khatello ea ente e boetse e phahame hanyenyane (khatello ea ente: 350 ~ 1300bar).Lebelo la ente: ho khothaletsoa ente e potlakileng.Ho molemo ho laola mocheso oa hlobo ho 45-75 ℃.Drying Handling: SA e na le thepa ea hygroscopic haeba e bolokiloe ka mokhoa o sa lokelang.
Maemo a khothalletsoang a ho omisa ke 80°C, lihora tse 2 ~ 4.Mocheso o qhibilihang: 200 ~ 270 ℃.Haeba lihlahisoa tse nang le marako a teteaneng li sebetsoa, mocheso o qhibilihang o ka tlaase ho moeli o ka tlaase o ka sebelisoa.Bakeng sa lisebelisoa tse matlafalitsoeng, mocheso oa hlobo ha oa lokela ho feta 60 ° C.Tsamaiso ea ho pholile e tlameha ho etsoa hantle, kaha mocheso oa hlobo o tla ama ka ho toba ponahalo, ho fokotseha le ho kobeha ha karolo.Limathi le liheke: Liheke tsohle tse tloaelehileng li ka sebelisoa.Boholo ba heke bo tlameha ho ba bo nepahetseng ho qoba li-streaks, matheba le li-voids.
3. Lethathamo le tloaelehileng la ts'ebeliso:
Motlakase (li-sockets, housings, joalo-joalo), lihlahisoa tsa letsatsi le letsatsi (lisebelisoa tsa kichineng, lisebelisoa tsa sehatsetsi, li-TV, mabokose a lik'hasete, joalo-joalo), indasteri ea likoloi (mabokose a khanyang, lisebelisoa, lisebelisoa, joalo-joalo), thepa ea ntlo (tafole, lijo. lithipa, joalo-joalo) joalo-joalo), likhalase tsa polokeho ea litlolo, matlo a sefene sa metsi le likonopo tsa lipompo.
Lihlahisoa tsa bongaka (li-syringe, li-tubes tsa aspiration mali, lisebelisoa tsa ho kenella ka renal le li-reactors).Lisebelisoa tsa ho paka (likotlolo tsa litlolo, matsoho a lipstick, libotlolo tsa mascara cap, likatiba, li-sprayers le li-nozzles, joalo-joalo), lihlahisoa tse khethehileng (matlo a lahlehang a bobebe, litsi tsa borashe le li-bristles, lisebelisoa tsa ho ts'oasa litlhapi, meno a maiketsetso, maqhama a borashe ba meno, lipene, li-nozzles tsa liletsa tsa mmino. le li-monofilaments tsa tataiso), joalo-joalo.
(4).Sekhomaretsi sa ABS (sekhomaretsi se sa khaoheng)
1. Ts'ebetso ea ABS:
ABS e entsoe ka li-monomers tse tharo tsa lik'hemik'hale, acrylonitrile, butadiene le styrene.(Monomer ka 'ngoe e na le thepa e fapaneng: acrylonitrile e na le matla a phahameng, botsitso ba mocheso le botsitso ba lik'hemik'hale; butadiene e na le ho tiea le ho hanyetsa tšusumetso; styrene e na le ts'ebetso e bonolo, qetello e phahameng le matla a phahameng. Li-monomers tse tharo Polymerization ea bongata e hlahisa terpolymer e nang le mekhahlelo e 'meli, a mohato o tsoelang pele oa styrene-acrylonitrile le mohato o qhalakantsoeng oa rabara ea polybutadiene.)
Ho ea ka pono ea morphological, ABS ke thepa ea amorphous e nang le matla a phahameng a mochine le thepa e ntle e akaretsang ea "mathata, boima le tšepe".Ke polymer ea amorphous.ABS ke polasetiki ea boenjiniere e sebelisoang ka kakaretso e nang le mefuta e fapaneng ea ts'ebeliso le mefuta e mengata ea ts'ebeliso.E boetse e bitsoa "polasetiki ea morero-kakaretso" (MBS e bitsoa transparent ABS).Metsi a boima hanyane), a honyela hanyane (0.60%), a tsitsitse ka mokhoa o itseng, 'me ho bonolo ho bopeha le ho sebetsa.
Thepa ea ABS e itšetlehile haholo ka karo-karolelano ea li-monomers tse tharo le sebopeho sa limolek'hule ka mekhahlelo e 'meli.Sena se lumella phetoho e kholo moralong oa sehlahisoa, 'me se hlahisitse makholo a lisebelisoa tsa boleng bo fapaneng tsa ABS' marakeng.Lisebelisoa tsena tsa boleng bo fapaneng li fana ka thepa e fapaneng e kang ho hanyetsa matla a mahareng ho isa holimo, ho ea holimo ho ea holimo le mocheso o phahameng oa ho sotha thepa, joalo-joalo thepa ea ABS e na le ts'ebetso e phahameng ea ts'ebetso, litšoaneleho tsa ponahalo, ho fokotseha ho tlaase le botsitso bo botle ba dimensional le matla a ts'usumetso e phahameng.
ABS ke bosehla bo bobebe bo bosehla bo bosehla kapa bo bosehla bo bosehla, bo se nang chefo, ha bo na monko, bo monya metsi a tlase, bo nang le lisebelisoa tse ntle tsa 'mele le tsa mochini, joalo ka thepa e ntle ea motlakase, ho hanyetsa ho roala, botsitso ba dimensional, khanyetso ea lik'hemik'hale le gloss ea holim'a metsi, joalo-joalo. ho sebetsa le sebopeho.Bothata ke ho hanyetsa boemo ba leholimo, mocheso o fokolang oa mocheso, le ho chesa.
2.Litšobotsi tsa ts'ebetso ea ABS
2.1 ABS e na le hygroscopicity e phahameng le kutloisiso ea mongobo.E tlameha ho omisoa ka botlalo le ho futhumatsoa pele e bōptjoa (bonyane lihora tse 2 ho 80 ~ 90C), 'me mongobo o lokela ho laoloa ka tlase ho 0.03%.
2.2 The melt viscosity ea ABS resin ha e utloe hantle mocheso (e fapane le li-resin tse ling tsa amorphous).
Leha mocheso oa ente ea ABS o phahame hanyane ho feta oa PS, e ke ke ea ba le sebaka sa ho futhumatsa se hlephileng joalo ka PS, 'me e ke ke ea sebelisa mocheso o foufetseng ho fokotsa viscosity ea eona.E ka eketsoa ka ho eketsa lebelo la screw kapa khatello ea ente ho ntlafatsa mokelikeli oa eona.Mocheso o akaretsang oa ho sebetsa ke 190-235 ℃.
2.3 The melt viscosity ea ABS e mahareng, e phahameng ho feta ea PS, HIPS, le AS, 'me ho hlokahala khatello e phahameng ea ente (500 ~ 1000bar).
Lisebelisoa tsa 2.4 ABS li sebelisa lebelo le mahareng le le phahameng le lebelo le leng la ente ho fihlela litholoana tse ntle.(Ntle le haeba sebopeho se rarahane 'me likarolo tse tšesaane tse nang le marako li hloka lebelo le phahameng la ente), boemo ba nozzle ea sehlahisoa bo atisa ho ba le maqhubu a moea.
Mocheso oa ho bopa oa 2.5 ABS o phahame, 'me mocheso oa hlobo hangata o fetoloa ho 25-70 °C.
Ha ho etsoa lihlahisoa tse khōloanyane, mocheso oa hlobo e tsitsitseng (mold e ka pele) hangata e ka ba 5 ° C holimo ho feta ea hlobo e tsamaeang (mold e ka morao).(Mocheso oa hlobo o tla ama pheletso ea likarolo tsa polasetiki, mocheso o tlase o tla fella ka pheletso e tlase)
2.6 ABS ha ea lokela ho lula ka moqomong o phahameng oa mocheso nako e telele haholo (e lokela ho ba ka tlase ho metsotso e 30), ho seng joalo e tla senyeha habonolo ebe e fetoha mosehla.
3. Mefuta e tloaelehileng ea lisebelisoa: likoloi (li-dashboards, li-hatch tsa lithulusi, likoahelo tsa mabili, mabokose a seipone, joalo-joalo), lihatsetsi, lisebelisoa tse matla haholo (li-dryer tsa moriri, li-blenders, li-processor tsa lijo, li-mowers tsa mohloa, joalo-joalo), mehala. , likoloi tsa boithabiso tse kang likariki tsa kolofo le li-jet skis.
Ho tsoela pele, haeba u batla ho tseba haholoanyane, ka kopo ikutloe u lokolohile ho ikopanya le rona.Baiyear ke feme e kholo e akaretsang e kopanyang ho etsa hlobo ea polasetiki, ho bopa ka ente le ho lokisa litšepe.Kapa u ka tsoela pele ho ela hloko setsi sa litaba sa sebaka sa rona sa marang-rang sa molao: www.baidasy.com, re tla tsoelapele ho ntlafatsa litaba tsa tsebo tse amanang le indasteri ea ho lokisa ente.
