Lub lim tiam dhau los, kev lag luam epoxy resin tsis muaj zog, thiab cov nqi hauv kev lag luam poob tsis tu ncua, uas feem ntau poob qis. Hauv lub limtiam, cov khoom siv raw bisphenol A ua haujlwm ntawm qis qis, thiab lwm yam khoom siv raw, epichlorohydrin, fluctuated downward in a nqaim range. Tag nrho cov nqi raw khoom tsis muaj zog nws qhov kev txhawb nqa rau cov khoom muag. Cov khoom siv raw khoom txuas ntxiv tau poob qis hauv txoj kev tsis muaj zog, thiab kev lag luam resin xav tau tsis zoo. Ntau yam tsis zoo ua rau tsis muaj peev xwm nrhiav tau qhov laj thawj zoo rau tus nqi ntawm epoxy resin. Cov lus hais ntawm qib thib ob thiab qib thib peb hom LER hauv khw tau raug xa tawm ntawm 15800 yuan / ton. Tus nqi ntawm cov tuam txhab loj loj tau poob mus rau theem qis tshaj xyoo no, thiab tseem muaj kev cia siab tias yuav txo tus nqi.
Lub lim tiam dhau los, lub Hoobkas loj hauv Jiangsu tau nres rau kev saib xyuas, thiab kev thauj khoom ntawm lwm cov nroj tsuag hloov me ntsis. Tag nrho cov khoom pib poob qis dua piv nrog lub lim tiam dhau los. Thaum lub sij hawm lub lim tiam, downstream qhov xav tau yog qeeb, thiab huab cua ntawm kev txiav txim tshiab yog lub teeb. Tsuas yog nyob rau hnub Wednesday dhau los, huab cua ntawm kev nug thiab kev rov ua dua tau zoo dua me ntsis, tab sis nws tseem yog tus thawj coj los ntawm tsuas yog xav tau ntxiv. Lub siab ntawm resin manufacturers rau nkoj yog siab, thiab qee lub Hoobkas tau hnov ​​​​tias cov khoom muag tau siab me ntsis. Muaj ntau cov paj hauv qhov kev thov, thiab kev tsom mus rau kev lag luam kev lag luam qis dua.
Bisphenol A: Lub lim tiam dhau los, kev siv peev xwm ntawm cov nroj tsuag hauv tsev bisphenol A yog 62.27%, nqis 6.57 feem pua ​​​​ntawm lub Kaum Ib Hlis 3. Hauv lub lim tiam no South Asia cov yas kaw thiab kev saib xyuas, Nantong Star Bisphenol A tsob nroj tau teem sijhawm kaw rau kev saib xyuas. rau ib lub lis piam rau lub Kaum Ib Hlis 7, thiab Changchun Tshuaj Kev Lag Luam tau teem sijhawm kaw rau kev saib xyuas rau ob kab (thawj kab uas yuav raug kaw. vim tsis ua hauj lwm rau lub Kaum Ib Hlis 6, uas xav tias yuav yog ib lub lis piam). Huizhou Zhongxin tau kaw ib ntus rau 3-4 hnub, thiab tsis muaj qhov txawv txav hauv kev thauj khoom ntawm lwm chav. Yog li ntawd, lub peev xwm siv tus nqi ntawm domestic bisphenol A nroj tsuag txo.
Epichlorohydrin: Lub lim tiam dhau los, lub peev xwm siv tus nqi ntawm kev lag luam hauv tsev epichlorohydrin yog 61.58%, nce 1.98%. Hauv lub limtiam, Dongying Liancheng 30000 t / ib tsob nroj propylene raug kaw thaum Lub Kaum Hli 26. Tam sim no, chloropropene yog cov khoom tseem ceeb, thiab epichlorohydrin tsis tau rov pib dua, thiab nws tseem nyob rau hauv cov txheej txheem ntawm kev soj ntsuam; Cov zis txhua hnub ntawm epichlorohydrin ntawm Binhua Pawg tau nce mus rau 125 tons kom sib npaug ntawm cov dej ntws los ntawm hydrogen chloride; Ningbo Zhenyang 40000 t / a glycerol txheej txheem cog tau rov pib dua rau lub Kaum Ib Hlis 2, thiab tam sim no cov zis txhua hnub yog li 100 tons; Dongying Hebang, Hebei Jiaao thiab Hebei Zhuotai tseem nyob hauv lub xeev ntawm chaw nres tsheb, thiab lub sijhawm rov pib dua yog ua raws; Kev ua haujlwm ntawm lwm cov lag luam muaj kev hloov me ntsis.
Kev ua lag luam yav tom ntej
Bisphenol Ib qho kev lag luam kev lag luam tau nce me ntsis nyob rau lub asthiv, thiab cov chaw lag luam hauv qab tau ceev faj ntau dua hauv kev nkag mus rau hauv kev ua lag luam. Cov kws tshuaj ntsuam xyuas kev lag luam ntseeg tias: kev xav ntawm cov neeg yuav khoom thiab cov neeg muag khoom yuav txuas ntxiv mus ua si ua si rau lub lim tiam tom ntej, nrog rau cov kev hloov pauv hauv lub sijhawm luv luv. Cov kev cia siab tsis muaj zog coj los ntawm cov cuab yeej tshiab yuav txwv tsis pub kev ua lag luam kev xav, thiab kev ua lag luam yuav tsum tau kho nyob ib puag ncig tus nqi kab.
Cyclic chloride tseem khiav qus. Cov khoom lag luam muaj txiaj ntsig zoo thiab cov lus xaiv uas North South ob chav yuav raug muab tso rau hauv kev tsim khoom rau lub hlis tom ntej ua rau cov neeg ua lag luam ceev faj thiab kev tos-thiab-pom huab cua hauv khw tseem tsis hloov pauv. Raws li kev txheeb xyuas ntawm cov neeg sab hauv, txawm hais tias kev ua lag luam tam sim no nyob ruaj khov ib ntus, nws muaj feem ntau tias kev lag luam yav tom ntej yuav pheej yig dua.
LER kev ua lag luam muab tsis tau tsuas yog muaj kev tsim cov khoom siv tu, tab sis kuj muaj cov tub rog tshiab nkag mus rau hauv kev ua lag luam. Nws tau nkag siab tias epoxy cog hauv Wuzhong, Zhejiang (Shanghai Yuanbang No.2 Factory) tau ua tiav rau hauv kev sim ua haujlwm ob peb hnub dhau los. Tom qab ob pawg, cov xim ntawm cov khoom tau mus txog 15 #. Yog tias nws tseem nyob ruaj khov rau yav tom ntej, cov khoom yuav tsis nkag mus rau hauv kev lag luam ntev. LER yuav txuas ntxiv nws qhov tsis muaj zog hu rov qab, nrog rau kev thov feem ntau rau kev yuav khoom nruj, thiab nws nyuaj rau pom cov cim ntawm kev rov qab los nyob rau lub sijhawm luv.
