Isiphelo esisezantsi carboxyl antimony ezamahala semi buthuntu LC uhlobo

inkcazelo emfutshane:

Iimpawu
Yenziwe nge-titanium edibeneyo eluhlaza kunye nesebenzayo i-DH hyti Catalysis (Lcej).I-lcej ayinazo iintsimbi ezinzima.
Isalathiso somgangatho sithelekiswa neeflakes ezikhanyayo ze-PET eziqulethe i-antimony, ngaphandle kokuba i-antimony ayibonakali kwaye iqela le-terminal carboxyl liphantsi.Inokunyusa i-viscosity.
Isiphelo esisezantsi se-carboxyl PET flakes / iifayibha / iifilimu kunye nezinye izinto zinokumelana okunamandla kwi-hydrolysis kunye ne-alkali.
Akukho antimony yensimbi enzima yafunyanwa kwiimveliso / iimveliso, akukho mfuduko we-antimony, ukhuselekile kwaye unempilo.
Iyakwazi ukusombulula ingxaki yomxholo we-antimony ngokugqithiseleyo ekushicileleni i-textile kunye nokudaya amanzi amdaka emveliso yezilwanyana ezifuywayo kunye ne-antimony kunye nokuhlangabezana neemfuno zemveliso ecocekileyo.

Isicelo

Inokuthi ijikelezwe ngokuthe ngqo / ifilimu yenziwe, okanye iqhutywe emva kokulinganisa;Ingasetyenziselwa i-membrane yeplate yangasemva, i-geotextile, ilaphu le-fiber ephezulu, njl.

Ixabiso eliphakathi lomxholo weqela le-carboxyl liya kumiselwa phakathi koluhlu lwe-≤ 28mol / T ngothethwano phakathi komthengisi kunye nomthengi.Xa sele imisiwe, ayisayi kutshintshwa ngokuzenzekelayo.

Ixabiso eliphakathi le-chromaticity b ixabiso liya kugqitywa ngamaqela omabini ngokubonisana phakathi koluhlu lwe-≤ 10. Xa sele imisiwe, ayiyi kutshintshwa ngokuthanda.

Ixabiso eliphakathi lomxholo we-diethylene glycol liya kugqitywa ngamaqela omabini ngokubonisana phakathi koluhlu lwe-≤1.5%.Xa sele kumisiwe, akusayi kutshintshwa ngokuthanda.

Isalathisi somxholo we-Antimony: Umda wokufumanisa le ndlela yi-10ppm, kwaye i-Nd ayibonakali.
