imikhiqizo

Izimpawu zesiNgisi

molecular isisindo modifier

impahla yamakhemikhali

Inezinhlobo eziningi, kufaka phakathi ama-aliphatic thiols, i-xanthate dilelfide, ama-polyphenols, isibabule, ama-halfides kanye nama-nitroso amakhompiyutha, futhi asetshenziswa kabanzi kuma-radical polymerization reactions

Ukwethulwa komkhiqizo nezici

Umlawuli Wesisindo Molecular ubhekisa ekungeneni kwenani elincane lezinto ezibonakalayo ezinokudluliselwa kwe-chain enkulu njalo ohlelweni lwe-polymerization. Ngoba ikhono lokudluliswa kwe-chain liqine ikakhulukazi, inani elincane kuphela le-Access linganciphisa isisindo esiphakeme kakhulu, kodwa futhi ngokushintsha umthamo ukuze lilawule isisindo se-molecular, ngakho-ke lolu hlobo lwe-agent yokudlulisa i-chain lubizwa nge-molecular yesisindo. Isibonelo, ama-dodecyl thiols ajwayele ukusetshenziswa njengabalawuli besisindo se-molecular ekukhiqizeni kwe-acrylic fiber. Umlawuli Wesisindo Molecular ubhekisa entweni engalawula isisindo se-polymer se-polymer futhi anciphise i-chain branch ye-polymer. Isimo saso ukuthi i-chain transfer ihlala inkulu kakhulu, ngakho-ke inani elincane linganciphisa ngempumelelo isisindo se-polymer, esilungele ukucubungula okuthunyelwe kanye nokusebenzisa i-polymer. Umlawuli amafushane, owaziwa nangokuthi i-polymerization Regulator

umsebenzi

Ku-emulsion polymerization yenjoloba yokwenziwa, imvamisa sebenzisa ama-aliphatic thiols (anjenge-dodecarbothiol, CH3 (CH3 (CH3 (CH3 (CH3 (CH3 (CH3 (CH3 (CH2 E-OleFem Proormination Polymerization, i-hydrogen isetshenziswa njengomlawuli wesisindo molecular.

iphakheji nokuhamba

B. Lo mkhiqizo ungasetshenziswa, 25kg, 200kg, 1000kg, umgqomo.
C. Isitolo esivalwe ngendawo epholile, eyomile futhi enomoya ongena ngaphakathi. Iziqukathi kufanele zivalwe ngokuqinile ngemuva kokusetshenziswa ngakunye ngaphambi kokusebenzisa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuhamba ukuvikela umswakama, i-alkali ne-acid, imvula nokunye ukungcola okukuxubana.
