Ntchito
Pafupifupi kuwonongeka konse kwa oyambitsa azo ndikuchita koyambirira, mtundu umodzi wokha wa free radical umapangidwa, ndipo palibe mbali yochitapo kanthu, chifukwa chake imagwiritsidwa ntchito kwambiri popanga mafakitale ndi kafukufuku wasayansi.Woyambitsa azo ali ndi zinthu zokhazikika ndipo ndi yabwino kusungirako ndi mayendedwe.Komabe, iyenera kusungidwa mufiriji poyenda, komanso kupewa kugundana kwamphamvu, kugundana, ndi kuphulika.Izi zimagwiritsa ntchito chochuluka polymerization, kuyimitsidwa polymerization ndi njira polymerization.
Kugwiritsa ntchito
Itha kugwiritsidwa ntchito ngati woyambitsa wa polymerization wa ethylenic monomers monga methyl methacrylate, komanso angagwiritsidwe ntchito ngati thovu wothandizira.
Zosungirako / njira zosungira
Izi zimasindikizidwa ndikusungidwa pa 2-6 ° C kuti zisakhudzidwe ndi kukangana.
Kupaka katundu
1kg odzaza thumba zotayidwa zojambulazo, 50kgs pa katoni ng'oma, mwatsatanetsatane chonde confirend ndi malonda.
Zolemba pamayendedwe ndi kasungidwe
Kuti ayende mu mapaketi a ayezi, amayenera kusindikizidwa ndikusungidwa pa kutentha kochepera 2-6 ° C.
