Tus nqi nruab nrab ntawm carboxyl kawg pawg cov ntsiab lus yuav tsum tau txiav txim siab nyob rau hauv thaj tsam ntawm ≤ 28mol / T los ntawm kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom.Thaum txiav txim siab, nws yuav tsum tsis txhob hloov arbitrarily.
Tus nqi nruab nrab ntawm chromaticity b tus nqi yuav tsum txiav txim siab los ntawm ob tog los ntawm kev sib tham nyob rau hauv qhov ntau ntawm ≤ 10. Thaum txiav txim siab, nws yuav tsum tsis txhob hloov pauv ntawm qhov xav tau.
Tus nqi nruab nrab ntawm diethylene glycol cov ntsiab lus yuav tsum tau txiav txim siab los ntawm kev pom zoo nyob rau hauv thaj tsam ntawm ≤1.5%.Thaum txiav txim siab, nws yuav tsum tsis txhob hloov ntawm qhov xav tau.
Antimony ntsiab lus index.Kev kuaj pom qhov txwv ntawm txoj kev no yog 10ppm, tsis muaj kev kuaj pom ntawm Nd.
1) Cov nqe lus them nqi yog dab tsi?
Feem ntau T / T, L / C thiab D / P, cov nqe lus them nqi tiag tiag thov kos nrog peb thaum tso xaj.
2) Ntev npaum li cas koj tus me nyuam tom qab tso qhov kev txiav txim?
Peb yuav npaj cov khoom xa tuaj sai li sai tau raws li lub sijhawm ua haujlwm thiab cov xwm txheej.Vim lub sij hawm shipping lossis lwm yam, thov nrog peb thaum muab xaj.
