Synonyms in English
i-molecular weight modifier
impahla yamakhemikhali
Inezinhlobo eziningi, okuhlanganisa i-aliphatic thiols, i-xanthate disulfide, i-polyphenols, isulfure, i-halides kanye nezinhlanganisela ze-nitroso, futhi isetshenziswa kabanzi ekuphenduleni kwe-polymerization yamahhala.
Isingeniso somkhiqizo kanye nezici
Isilawuli sesisindo samangqamuzana sibhekisela ekwengezweni kwenani elincane lezinto ezinomthamo omkhulu wokudluliswa kweketango ohlelweni lwe-polymerization.Ngenxa yokuthi ikhono lokudlulisa amaketanga linamandla ikakhulukazi, inani elincane kuphela lokungeza linganciphisa kakhulu isisindo samangqamuzana, kodwa futhi ngokulungisa umthamo ukuze ulawule isisindo samangqamuzana, ngakho lolu hlobo lwe-agent yokudlulisa amaketanga lubizwa nangokuthi isilawuli sesisindo samangqamuzana.Isibonelo, ama-dodecyl thiols avame ukusetshenziswa njengezilawuli zesisindo samangqamuzana ekukhiqizeni i-acrylic fiber.Isilawuli sesisindo samangqamuzana sibhekisela entweni engalawula isisindo samangqamuzana e-polymer futhi yehlise i-chain branching ye-polymer.Isici saso ukuthi ukudluliswa kweketango njalo kukhulu kakhulu, ngakho-ke inani elincane linganciphisa ngempumelelo isisindo samangqamuzana e-polymer, esivumelana nokucubungula nokusetshenziswa kwe-polymer.Isilawuli ngamafuphi, owaziwa nangokuthi isilawuli se-polymerization
sebenzisa
Ku-emulsion polymerization yerabha yokwenziwa, ngokuvamile kusetshenziswa i-aliphatic thiols (njenge-dodecarbothiol,CH3 (CH2) 11SH) kanye ne-disulphide diisopropyl xanthogenate (okungukuthi, i-butyl yesilawuli)C8H14O2S4, ikakhulukazi i-aliphatic thiols, futhi isheshise ukusabela;Ku-olefin coordination polymerization, i-hydrogen isetshenziswa njengesilawuli sesisindo samangqamuzana.
iphakethe kanye nezokuthutha
B. Lo mkhiqizo ungasetshenziswa, 25KG, 200KG, 1000KG, umphongolo.
C. Gcina kuvaliwe endlini epholile, eyomile futhi engenamoya.Iziqukathi kufanele zivalwe ngokuqinile ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthutha ukuvimbela umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
