Raws li lub Cuaj Hlis 16, cov khoom lag luam tshuaj tus nqi ntsuas (CCPI) tau kaw ntawm 5199 cov ntsiab lus, nce ntawm 0.6%.
Ntawm cov khoom lag luam tshuaj tseem ceeb, tag nrho ntawm 37 cov khoom lag luam tau nce, suav txog 59.7%, thiab cov khoom lag luam uas nce siab tshaj plaws yog adipic acid (7.3%) thiab butyl acrylate (7.1%);tag nrho ntawm 13 cov khoom poob, suav txog 21.0%, thiab cov khoom lag luam uas poob siab tshaj plaws yog (4.3%) thiab acetonitrile (3.3%).
Adipic acid: Kev lag luam rally yog pom tseeb.Tus nqi ntawm cov khoom siv raw tau nce siab nyob rau lub lim tiam, ua ke nrog kev ncua sijhawm rov pib dua Haili cog, uas txhawb nqa tag nrho lub siab.Tom qab hnub so, cov tuam txhab adipic acid tau tsa tus nqi teev npe ob zaug, thawb tus nqi lag luam.Nws tsis zoo li tias adipic acid yuav nce siab ntxiv hauv kev ua lag luam pom.
Butyl Acrylate: Kev ua lag luam tau nce dav.Ntau qhov chaw tsim khoom tau nres, thiab cua daj cua dub cuam tshuam rau kev xa khoom ntawm cov chaw tsim khoom hauv Jiangsu, Zhejiang thiab Shanghai, thiab tag nrho cov khoom siv hauv thaj teb tau nruj.Kev txhawb nqa los ntawm cov nyiaj tau los, lub Hoobkas butyl ester tau nthuav dav hauv cov hnub tsis ntev los no, thiab kev lag luam kev lag luam tau ua raws li kev cai, thiab lawv tsis kam muag ntawm tus nqi qis.Nws cia siab tias kev lag luam butyl acrylate yuav khiav tau zoo.
PVC: Kev lag luam sawv thiab tom qab ntawd poob.Thaum pib ntawm lub lim tiam, cov huab cua hauv tsev tau zoo dua qub, tsav PVC cov nqi nce.Hnub Wednesday, Asmeskas cov ntaub ntawv nyiaj txiag nce siab tshaj qhov kev cia siab, Fed qhov kev cia siab ntawm cov paj laum nce siab ntxiv, cov huab cua macro tsis muaj zog, thiab cov nqi tau hloov pauv thiab poob.Nws cia siab tias tus nqi ntawm PVC hauv kev ua lag luam kev pom zoo yuav txuas ntxiv hloov mus rau ntau yam.
Acetonitrile: Kev ua lag luam tau poob los ntawm qib siab.Nyob rau theem pib, ntau pawg ntawm acrylonitrile units tau kho dua nyob rau hauv lub hauv paus, thiab tus nqi ntawm cov khoom los ntawm acetonitrile tau nce sai heev.Txawm li cas los xij, qhov kev thov ntawm cov tshuaj tua kab hauv qab thiab lwm yam kev lag luam rau acetonitrile yog qhov dav dav, thiab kev tos-thiab-pom tus cwj pwm tau txais yuav rau cov nqi siab acetonitrile, thiab cov lus hais ntawm acetonitrile maj mam rov qab los rau qhov muaj feem.Nws cia siab tias kev ua lag luam acetonitrile yuav poob mus ntxiv rau yav tom ntej.
Isobutyraldehyde: Tus nqi lag luam hauv tsev ntawm isobutyraldehyde txuas ntxiv poob qis.Lub Tianjin tshuaj cog tau rov ua haujlwm ib txwm ua, thiab cov khoom siv ntawm isobutyraldehyde tau nce ntxiv.Txawm li cas los xij, qhov kev thov qis qis qis, thiab lub Hoobkas tseem ceeb ntawm kev xa khoom xa tuaj yog qhov tseem ceeb, thiab qee lub tuam txhab kev muab tau qis dua.Nrog rau tus nqi poob ntawm isobutyraldehyde, kev ua lag luam muaj zog tos-thiab-pom huab cua.
Titanium dioxide: Tus nqi lag luam hauv tsev ntawm titanium dioxide txuas ntxiv poob.Kev ua lag luam ib txwm ua tau zoo tsis muaj zog thaum lub caij nyoog ntawm kev thov, thiab qhov kev thov tsis tau nce ntau.Kev lag luam coatings tau raug daig hauv kev poob qis hauv kev lag luam vaj tsev, thiab tus nqi ntawm cov khoom siv raw titanium concentrate tau qis me ntsis.Tus nqi ntawm sulfuric acid txuas ntxiv qis.Titanium dioxide Lub khw tseem tsis muaj zog.
Nyob rau hauv tag nrho, nyob rau lub sij hawm luv luv, "Golden Nine Silver Ten" lub caij noj qab haus huv yuav txuas ntxiv ua rau kev xav tau rov qab los, tab sis kev pheej hmoo ntawm kev nom kev tswv thiab kev lag luam thoob ntiaj teb tseem tsis muaj kev cuam tshuam, thiab kev lag luam tshuaj muaj qhov txwv tsis pub muaj kev loj hlob ntxiv thaum muaj kev rov qab los ntawm cov neeg tsis muaj zog. terminal xav tau.
JIN DUN CHEMICALtau tsim tshwj xeeb (meth) acrylic monomer manufacturing puag hauv ZHEJIANG xeev.Qhov no ua kom cov khoom ruaj khov ntawm HEMA, HPMA, HEA, HPA, GMA nrog qib siab zoo.Peb tshwj xeeb acrylate monomers yog dav siv rau thermosetting acrylic resins, crosslinkable emulsion polymers, acrylate anaerobic adhesive, ob-tivthaiv acrylate nplaum, hnyav acrylate nplaum, emulsion acrylate nplaum, ntawv xov thiab pleev xim acrylic resins. thiab tshwj xeeb (meth) acrylic monomers thiab derivatives.Xws li cov fluorinated acrylate monomers, Nws tuaj yeem siv dav hauv txheej txheej tus neeg sawv cev, xim, inks, photosensitive resins, cov khoom siv kho qhov muag, kho fiber ntau, hloov kho rau cov yas lossis roj hmab teb.Peb tab tom npaj los ua tus neeg muag khoom sab saum toj hauv thaj teb ntawmtshwj xeeb acrylate monomers, los qhia peb cov kev paub nplua nuj nrog cov khoom zoo dua qub thiab kev pabcuam tshaj lij.
