isilungisi sesisindo sama-molecule
impahla yamakhemikhali
Inezinhlobo eziningi, okuhlanganisa ama-aliphatic thiols, i-xanthate disulfide, ama-polyphenols, i-sulfur, ama-halides kanye nama-nitroso compounds, futhi isetshenziswa kabanzi ekuphenduleni kwe-free radical polymerization.
Isingeniso somkhiqizo kanye nezici
Isilawuli sesisindo sama-molecule sibhekisela ekufakweni kwenani elincane lezinto ezihambisana nokuguquguquka okukhulu kweketanga ohlelweni lwe-polymerization. Ngenxa yokuthi ikhono lokudlulisa iketanga linamandla kakhulu, inani elincane kuphela lokwengeza linganciphisa kakhulu isisindo sama-molecule, kodwa futhi ngokulungisa umthamo ukuze kulawulwe isisindo sama-molecule, ngakho-ke lolu hlobo lwe-ejenti yokudlulisa iketanga lubizwa nangokuthi i-molecule weight regulator. Isibonelo, ama-dodecyl thiols avame ukusetshenziswa njengabalawuli besisindo sama-molecule ekukhiqizweni kwe-acrylic fiber. Isilawuli sesisindo sama-molecule sibhekisela entweni engalawula isisindo sama-molecule se-polymer futhi inciphise ukuhlanganiswa kweketanga le-polymer. Isici sayo ukuthi i-chain transfer constant inkulu kakhulu, ngakho inani elincane linganciphisa ngempumelelo isisindo sama-molecule se-polymer, okusiza ekucutshungulweni nasekusetshenzisweni kwe-polymer. Isilawuli ngamafuphi, esaziwa nangokuthi i-polymerization regulator
sebenzisa
Ku-polymerization ye-emulsion yerabha yokwenziwa, ngokuvamile kusetshenziswa ama-aliphatic thiols (njenge-dodecarbothiol, CH3 (CH2) 11SH) kanye ne-disulphide diisopropyl xanthogenate (okungukuthi, i-regulator butyl)C8H14O2S4, ikakhulukazi ama-aliphatic thiols, futhi kusheshiswe ukusabela; Ku-polymerization ye-olefin coordination, i-hydrogen isetshenziswa njengomlawuli wesisindo sama-molecule.
iphakheji kanye nokuthuthwa
B. Lo mkhiqizo ungasetshenziswa, 25KG, 200KG, 1000KG, umphongolo.
C. Gcina kuvaliwe endaweni epholile, eyomile futhi enomoya opholile ngaphakathi. Izitsha kufanele zivalwe kahle ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthuthwa ukuze kuvinjelwe umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
