Mawu ofanana mu Chingerezi
chosinthira kulemera kwa molekyulu
katundu wa mankhwala
Ili ndi mitundu yambiri, kuphatikizapo aliphatic thiols, xanthate disulfide, polyphenols, sulfure, halides ndi nitroso compounds, ndipo imagwiritsidwa ntchito kwambiri mu free radical polymerization reactions.
Chiyambi cha malonda ndi zinthu zake
Wowongolera kulemera kwa mamolekyulu amatanthauza kuwonjezera zinthu zochepa zokhala ndi kusamutsa unyolo waukulu mu dongosolo la polymerization. Chifukwa mphamvu yosamutsa unyolo ndi yamphamvu kwambiri, kuwonjezera pang'ono kokha kumatha kuchepetsa kulemera kwa mamolekyulu, komanso kusintha mlingo kuti ulamulire kulemera kwa mamolekyulu, kotero mtundu uwu wa chothandizira kusamutsa unyolo umatchedwanso wowongolera kulemera kwa mamolekyulu. Mwachitsanzo, dodecyl thiols nthawi zambiri amagwiritsidwa ntchito ngati owongolera kulemera kwa mamolekyulu popanga ulusi wa acrylic. Wowongolera kulemera kwa mamolekyulu amatanthauza chinthu chomwe chingawongolere kulemera kwa mamolekyulu a polima ndikuchepetsa nthambi ya unyolo wa polima. Khalidwe lake ndilakuti kusamutsa unyolo ndi kwakukulu kwambiri, kotero pang'ono kumatha kuchepetsa kulemera kwa mamolekyulu a polima, zomwe zimathandiza kukonza ndikugwiritsa ntchito polima. Wowongolera mwachidule, yemwe amadziwikanso kuti wowongolera polymerization.
gwiritsani ntchito
Mu emulsion polymerization ya mphira wopangidwa, nthawi zambiri amagwiritsa ntchito aliphatic thiols (monga dodecarbothiol,CH3 (CH2) 11SH) ndi disulphide diisopropyl xanthogenate (ndiko kuti, regulator butyl)C8H14O2S4, makamaka aliphatic thiols, ndikufulumizitsa reaction; Mu olefin coordination polymerization, hydrogen imagwiritsidwa ntchito ngati molecular weight regulator.
phukusi ndi mayendedwe
B. Chogulitsachi chingagwiritsidwe ntchito, 25KG, 200KG, 1000KG, mbiya.
C. Sungani yotsekedwa m'nyumba pamalo ozizira, ouma komanso opumira mpweya. Zidebe ziyenera kutsekedwa bwino mukatha kugwiritsa ntchito nthawi iliyonse musanagwiritse ntchito.
D. Chogulitsachi chiyenera kutsekedwa bwino panthawi yonyamula kuti chisasakanikirane ndi chinyezi, alkali ndi asidi wamphamvu, mvula ndi zinyalala zina.
