Nyob rau hauv cov cua fais fab kev lag luam, epoxy cob tam yog tam sim no dav siv hauv cua tshuab cov khoom siv. Epoxy Resin yog cov khoom siv ua haujlwm siab nrog cov khoom siv kho tau zoo, tshuaj lom neeg ruaj khov, thiab corrosion tsis kam. Nyob rau hauv kev tsim khoom ntawm cov cua tshuab cua tshuab tuaj, Epoxy Resin yog dav siv nyob rau hauv cov txheej txheem txheej txheem, cov sib txuas, thiab txheej ntawm cov hniav. Epoxy Resin muaj peev xwm muab lub zog siab, siab tawv, thiab qaug zog ntawm cov hniav, kom sib txuas ntawm cov hniav ruaj khov thiab kev ntseeg tau ntawm cov hniav.

Epoxy Resin kuj tseem tuaj yeem txhim kho cov cua shear thiab cuam tshuam ntawm cov hniav, txo cov hniav kev co suab nrov, thiab txhim kho cov cua tshuab hluav taws xob ua tau zoo. Tam sim no Epoxy Resin thiab iav Fiber hloov kho yog tseem siv ncaj qha rau hauv cov khoom cua tshuab, uas tuaj yeem txhim kho lub zog thiab corrosion tsis kam.

Hauv cov khoom siv cua tshuab cov hniav, daim ntawv thov ntawm Epoxy Resin tseem yuav tsum siv cov khoom siv tshuaj lom xws li cov tshuaj tiv thaiv thiab cov neeg ceev nrawm:

Firstly, feem ntau siv Epoxy Resin Chais Tus Neeg Sawv Cev hauv cov cua lub zog kev lag luam yog polyether hoine

Ib qho khoom lag luam yog polyether amine, uas tseem yog feem ntau siv epoxy resin kho tus neeg sawv cev cov khoom lag luam hauv kev lag luam cua. Polyether Amine Epoxy Resin Tus Kws Tshuaj Tiv Thaiv yog siv nyob rau hauv kev kho ntawm Matrix Epoxy Resin thiab cov nplaum nplaum. Nws muaj cov khoom siv dav dav zoo xws li lub neej tsis muaj zog, cov neeg siv hluav taws xob, choj thiab nkoj waterproofing, roj thiab shale roj kev tshawb nrhiav thiab lwm daim teb. Cov dej hauv qab ntawm polyether amine account rau ntau tshaj 62% ntawm cua fais fab. Nws yuav tsum raug sau tseg tias polyether amines koom rau organic amine epoxy resins.

Raws li kev tshawb nrhiav, cov cim nyiaj polyeth tuaj yeem muab tau los ntawm kev kho cov polyethylene glycol, propylene glycolers nyob rau hauv kub thiab siab. Xaiv cov qauv sib txawv polyoxoalkyl cov qauv tuaj yeem kho cov kev ua yeeb yam, kev nyuaj, viscosity, thiab hydrophilicity ntawm polyether amines. Polyether Amine muaj qhov zoo ntawm kev ruaj khov zoo, tsawg dua whitening tom qab kho, thiab siab hardness. Nws tseem tuaj yeem ua rau hauv cov kuab tshuaj xws li dej, ethanol, hydrocarbons, esters, ethylene glycole glycole, thiab ketones.

Raws li kev sojntsuam, kev siv cov khoom siv Isine Polyether Amine ua lag luam tau tshaj 100000 tons, qhia kev loj hlob ntawm ntau dua 25% nyob rau ob peb xyoos dhau los. Nws cia siab tias los ntawm 2025, kev lag luam ntim ntawm polyether amines hauv Suav teb yuav tshaj li 150000 tons hauv cov lus qhia luv luv, thiab cov khoom noj muaj txiaj ntsig ntawm kev coj ua ntawm polyether yog xav kom nyob ib ncig ntawm 8% yav tom ntej.

Kev ua lag luam ntau lawm ntawm polyether amine hauv Suav teb yog Chenhua Co., Ltd., uas muaj ob lub hauv paus ntau lawm hauv Yangzhou thiab Huai'an. Nws muaj tag nrho ntawm 31000 tons / xyoo ntawm polyety-ncia polyether) (35000 tons / xyoo ntawm alkscosides, 348 tons / xyoo ntawm nplaim taws retardants , 8500 tons / xyoo ntawm silicone roj hmab, 45400 tons / xyoo ntawm polyether, 4600 tons / xyoo cov peev txheej ntawm 100 tons / xyoo. Yav Tom Ntej Chanhhua Pab Pawg Phiaj Los Nqis Tes Ua Ntej 600 lab yuan Hauv Huai'an Industrial Amine thiab 42000 Tons Ntawm Polyether Project.

Ib qho ntxiv, cov neeg sawv cev ntawm cov lag luam hauv Suav teb suav nrog Wuxi Acoli, Yantai Minsheng, Shandong Zhengda, Real Madrid Technology, thiab Wanhua tshuaj lom neeg. Raws li kev txheeb cais ntawm kev npaj ua haujlwm, lub sijhawm ntev npaj ntau lawm ntawm polyether amines hauv Suav teb yuav tshaj 200000 tons nyob rau yav tom ntej. Nws cia siab tias lub sijhawm ntev ntau lawm ntawm polyether amines hauv Suav teb yuav tau tshaj 300000 txoj kev loj hlob nyob rau ib xyoos, thiab kev loj hlob ntev ntev yuav yog siab.

Thib ob, nrawm tshaj plaws epoxy resin kho tus neeg sawv cev hauv cov cua fais fab kev lag luam: methyltetrhaydrothricic anhydride

Raws li kev sojntsuam, kev tshawb nrhiav nrawm tshaj Epoxy Resin Chais Tus Neeg Sawv Cev hauv cov cua kev lag luam yog methylitetrhayrosthhalic anhydride caping tus neeg sawv cev. Hauv tshav pob cua fais fab tuag cov neeg sawv cev, tseem muaj methyl tetrahydride epoxy resin raws cov khoom siv roj carbon monoxal) extrusion moulding txheej txheem. MTHPA kuj tseem siv rau hauv cov ntaub ntawv hauv tshuab hluav taws xob, cov tshuaj, tshuaj tua kab, cov txiaj ntsig, thiab kev tiv thaiv kev lag luam hauv ntiaj teb. Methyl tetrahydraphthhalic anhydride anhydride anhydride yog ib qho tseem ceeb sawv cev ntawm anhydride caping tus neeg sawv cev thiab tseem muaj hom tshuaj tiv thaiv kom nrawm rau yav tom ntej.

Methyltyrophtudrophtic anhydride anhydride anhydride yog synthesized los ntawm txiv neej methydrig thiab methylbutadiene los ntawm kev siv hluavtaws ntawm kev siv hluavtaws thiab tom qab ntawd isomerized. Cov kev ua lag luam hauv tsev yog Pyyang Huichng Electronic Ntaub Ntawv Co., Ltd., nrog kev noj nplai ntawm ib txhiab tons hauv Suav. Nrog kev lag luam sai sai thiab kev siv hloov kho kev loj hlob, qhov xav tau rau kev loj hlob, ntxiv rau kev loj hlob ntawm methyl tetrathydrescthhalic anhydride khw.

Ib qho ntxiv, muaj mob ib ce tua cov neeg sawv cev kuj suav nrog TetrahyDrothhalic anhydra, MethylraStydrigs JHYLRIDE MHMA, Methylra

Thib peb, Epoxy Resin Chais Tus Neeg sawv cev nrog kev ua tau zoo tshaj plaws hauv cov cua kev lag luam suav nrog isophorone diamine thiab methylcychlohexane txoj cai

Ntawm epoxy resin kho tus neeg sawv cev cov khoom lag luam, cov tshuaj ntsuam xyuas zoo tshaj plaws, mexahydrophtandride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride anhydride Tshuaj Kho Neeg Tus Neeg Sawv Cev Muaj Khoom Siv Zoo Li Cas, Lub sijhawm ua haujlwm tsim nyog, kev kho cov txheej txheem kub tsawg, thiab ua tiav kev txhaj tshuaj zoo, thiab tau thov hauv cov ntaub ntawv sib xyaw ntawm epoxy cob thiab iav fiber ntau rau cua tshuab tuaj. Anhydride caping tus neeg sawv cev rau cov cua sov kho thiab tsim nyog dua rau cov txheej txheem moulding ua haujlwm ntawm cov cua tshuab hluav taws xob.

Lub ntiaj teb ntau lawm cov lag luam ntawm isophorone diamond muaj xws li Basf Ap hauv Tebchaws Asmeskas, Dupont hauv Tebchaws Asmeskas, BP hauv Tebchaws Askiv. Ntawm lawv, evonik yog qhov loj tshaj plaws isophorone ntawm kev lag luam hauv ntiaj teb. Cov neeg lag luam tseem ceeb hauv Suav teb yog Evonik Shanghai, Wanhaha tshuaj, Tongling Hengxing tshuaj, thiab lwm yam, nrog kev siv nyiaj nplai ntawm 100000 tons nyob rau Suav teb.

Methylcyclohexanediamine yog feem ntau sib tov ntawm 1-methyl-2,4-cyclohexanediamine thiab 1-methyl-2,6-cyclohexanediamine. Nws yog ib qho kev sib xyaw ua ke loj hlob cycloalkyl compound tau los ntawm hydrogenation ntawm 2.4-diamiotoluene. Methylcyclohexanediamine tuaj yeem siv ib leeg ua tus kws kho mob epoxy, thiab lwm yam acid epsdrides, thiab lwm yam) lossis cov amines , iMidazole). Cov neeg tsim khoom ntawm methylolyclohexane cov tub sab nyob hauv Suav teb muaj pes tsawg leej thiab Jiangeter Weibe Technology Chemical Technology yog li 7000 tons.

Nws yuav tsum raug sau tseg tias cov organic amine caping tus neeg sawv cev tsis yog ib puag ncig tus neeg sawv cev, tab sis lawv yog lub sijhawm ua haujlwm ntev dua thiab lub sijhawm ua haujlwm tau muab piv rau tus neeg kho mob hawb pob.

Tuam Tshoj muaj ntau hom Epoxy Resin Tus Kws Tshuaj Kho Hauv Cov Khoom Siv Hluav Taws Xob, tab sis cov khoom tseem ceeb siv yog ib leeg. Txoj kev ua lag luam thoob ntiaj teb yog nquag tshawb nrhiav thiab tsim cov tshiab Epoxy Resin tus neeg sawv cev tus neeg sawv cev, thiab tus neeg saib xyuas tus neeg sawv cev yog kev hloov kho tas li thiab cuam tshuam. Kev nce qib ntawm cov khoom lag luam hauv Suav lag luam qeeb, feem ntau yog vim tus nqi tsim kho mob Epoxy tus neeg sawv cev hauv cov cua kev lag luam, thiab qhov tsis muaj cov khoom lag luam zoo. Txawm li cas los xij, nrog kev nce qib nruam kev ua haujlwm ntawm epoxy Resin Chais Tus Neeg Sawv Cev hauv cov cua lub teb hluav taws xob kuj tseem yuav ua kom hloov chaw tsis tu ncua thiab cov iterations.
