Antimony yaulere yapamwamba kwambiri ya L-mtundu
Itha kugwiritsidwa ntchito popanga ulusi wa poliyesitala komanso ulusi.Ndizinthu zobiriwira zobiriwira zamabizinesi a polyester kuti azikonza ulusi ndi zinthu zina zofananira.
Mndandanda wamtundu wa DH hyti antimony waulere wapamwamba kwambiri wa L-mtundu wa PET chip

Mtengo wapakati wazomwe zili mugulu lomaliza la carboxyl udzatsimikiziridwa mkati mwa ≤ 28mol / T kudzera muzokambirana pakati pa wogulitsa ndi wogula.Akatsimikiziridwa, sichidzasinthidwa mosasamala.
Mtengo wapakati wa mtengo wa chromaticity b udzatsimikiziridwa ndi mbali zonse ziwiri kupyolera mu zokambirana mkati mwa ≤ 10. Mukatsimikiziridwa, sichidzasinthidwa mwakufuna.
Mtengo wapakati wa diethylene glycol uyenera kutsimikiziridwa ndi mgwirizano wapakati pa ≤1.5%.Zikatsimikiziridwa, sizidzasinthidwa mwakufuna.
Antimony content index.Malire odziwika a njirayi ndi 10ppm, palibe kuzindikira kwa Nd.
1) Malipiro ndi chiyani?
Makamaka T/T, L/C ndi D/P, mawu enieni olipira chonde funsani nafe potumiza maoda.
2) Kodi kutumiza kwanu kumatenga nthawi yayitali bwanji mutatha kuyitanitsa?
Tidzakonza zotumiza nthawi yomweyo malinga ndi dongosolo la dipatimenti yopanga ndi momwe zinthu zilili.Chifukwa cha ndandanda yotumizira kapena zinthu zina, chonde funsani nafe potumiza maoda.
