5 、 Kev txheeb xyuas kev lag luam hauv qab

Epoxy resin: cuam tshuam los ntawm qhov chaw nres tsheb xov xwm ntawm upstream ECH manufacturers, lub domestic epoxy resin ua lag luam tau ntsib ib tug nqaim upward sib. Txawm hais tias feem ntau cov tuam txhab tau ua siab ntev nce lawv cov lus hais, cov chaw nres tsheb hauv qab tau ceev faj thiab qeeb ua raws li qhov xav tau, ua rau qhov tsis txaus tag nrho qhov kev txiav txim tso.

Kev ua lag luam PC: Hnub Friday dhau los, kev lag luam hauv tsev PC txuas ntxiv ua kom tsis muaj zog thiab tsis muaj zog sib koom ua ke. Tus nqi ntau yam ntawm cov ntaub ntawv qib txhaj tshuaj nyob rau thaj tsam East China tau hloov pauv, nrog qee qhov chaw ntawm lub ntiajteb txawj nqus poob piv rau hnub ua lag luam dhau los. Kev ua lag luam muaj zog tos-thiab-pom kev xav, downstream kev xav yuav yog qeeb, thiab kev lag luam huab cua yog lub teeb.

6 、 Cov kev cia siab yav tom ntej

Raws li kev txheeb xyuas kev lag luam tam sim no, nws xav tias qhov chaw ua lag luam rau bisphenol A yuav txuas ntxiv hloov pauv thiab poob rau lub lim tiam no. Txawm hais tias tus nqi raw khoom txo qis, tus nqi siab ntawm bisphenol A tseem ceeb heev. Qhov kev tsis sib haum xeeb ntawm kev xav tau tsis tau txo qis, thiab nrog rau hnub so National Day, downstream stocking xav tau maj mam poob qis. Muaj qhov tshwm sim siab uas lub khw muag khoom bisphenol A yuav tuav qhov kev sib koom ua ke nqaim hauv ob hnub ua haujlwm ntawm lub lim tiam no.
