Antimony yaulere yapamwamba kwambiri ya L-mtundu

Kufotokozera mwachidule:

Makhalidwe
Amapangidwa ndi wobiriwira komanso wogwira ntchito wosakanizidwa wa titaniyamu DH hyti Catalysis (Lcej).lcej ilibe zitsulo zolemera.
Mndandanda wamtundu wake umafanana ndi ma flakes owala kwambiri a PET okhala ndi antimony, kupatula kuti antimony sapezeka ndipo zomwe zili mugulu la terminal carboxyl ndizochepa.Ikhoza kuonjezera mamasukidwe akayendedwe.
Low-end carboxyl PET flakes/fibers/films ndi zinthu zina zimalimbana kwambiri ndi hydrolysis ndi alkali.
Palibe antimoni yachitsulo yolemera yomwe yapezeka muzogulitsa/zogulitsa, palibe kusamuka kwa antimoni, otetezeka komanso athanzi.
Itha kuthana ndi vuto la kuchuluka kwa antimoni pakusindikiza nsalu ndikudaya madzi otayidwa azinthu zapanyumba zomwe zimakhala ndi antimoni ndikukwaniritsa zofunikira pakupanga ukhondo.

Kugwiritsa ntchito

Itha kugwiritsidwa ntchito popanga ulusi wa poliyesitala komanso ulusi.Ndizinthu zobiriwira zobiriwira zamabizinesi a polyester kuti azikonza ulusi ndi zinthu zina zofananira.

Zomwe Zimachitika

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.

FAQ

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.
