Cam khwb cia hlau yeeb nkab epoxy resin yuav tsum tau mus txog 350 teev ntawm ntsev tsuag tshuaj ntsuam raws li EN877 tus qauv, tshwj xeeb tshaj yogDS sml yeeb nkab tuaj yeem ncav cuag 1500 xuab moos ntawm ntsev tsuagxeem(tau txais Hong Kong CASTCO ntawv pov thawj hauv 2025). Pom zoo siv rau hauv qhov chaw ntub dej thiab los nag, tshwj xeeb tshaj yog nyob rau ntawm ntug dej hiav txwv, epoxy resin txheej ntawm cov ntaub thaiv npog sab nrauv ntawm DS SML yeeb nkab muab kev tiv thaiv zoo rau cov yeeb nkab. Nrog rau kev siv cov tshuaj hauv tsev ntau ntxiv xws li cov organic acids thiab caustic soda, epoxy txheej yog qhov zoo tshaj plaws tiv thaiv cov khoom tsis zoo, thaum tseem tsim cov kav dej du kom tsis txhob muaj av clogging. Cov khoom tiv thaiv corrosion ntawm cov kav hlau cam khwb cia ua rau nws siv dav hauv chav kuaj, tsev kho mob, chaw tsim khoom thiab chaw nyob thoob ntiaj teb.
Txawm li cas los xij, yog tias cov xim tsis khaws cia kom zoo, nws yuav ua rau cov yeeb nkab hlau cam khwb cia ua kom sib dua lossis tsis muaj xim tom qab pleev xim, cuam tshuam rau qhov zoo nkauj thiab kev tiv thaiv ntawm cov khoom.
1. Txoj kev cia kom raug ntawm A1 epoxy xim
A1 epoxy xim yog cov txheej txheem tiv thaiv kev ua haujlwm siab, thiab nws cov xwm txheej khaws cia ncaj qha cuam tshuam rau kev ruaj ntseg ntawm txheej thiab txheej txheej. Txoj kev khaws cia kom raug suav nrog cov hauv qab no:
1. Kev tswj qhov kub thiab txias
Qhov kub thiab txias: A1 epoxy xim yuav tsum muab khaws cia rau hauv ib puag ncig ntawm 5 ℃ ~ 30 ℃ kom tsis txhob muaj qhov kub siab lossis qis uas cuam tshuam rau cov tshuaj lom neeg ruaj khov ntawm cov xim.
Tsis txhob kub siab heev:Kub kub (> 35 ℃) yuav ua rau cov kuab tshuaj nyob rau hauv cov xim evaporate sai heev, thiab cov resin tivthaiv tej zaum yuav raug polymerization cov tshuaj tiv thaiv, uas yuav ua rau kom cov viscosity ntawm cov xim los yog txawm ua rau curing tsis ua hauj lwm.
Tsis tshua muaj kub (<0 ℃) tej zaum yuav ua rau tej yam khoom nyob rau hauv cov xim mus crystallize los yog sib cais, ua rau txo adhesion los yog xim tsis sib xws tom qab painting.
2. Kev tswj cov av noo
Ib puag ncig qhuav: Cov av noo ntawm qhov chaw khaws cia yuav tsum tau tswj ntawm 50% thiab 70% txhawm rau tiv thaiv huab cua tsis zoo los ntawm kev nkag mus rau lub thoob xim.
Sealed thiab noo noo-pov thawj: Lub thoob xim yuav tsum nruj nreem kaw kom tsis txhob ya raws los ntawm kev nkag mus, txwv tsis pub nws yuav ua rau cov xim stratification, agglomeration los yog txawv txav.
3. Cia deb ntawm lub teeb
Tsis txhob raug tshav ntuj ncaj qha: Ultraviolet rays yuav ua rau kom cov laus ntawm epoxy resin, ua rau cov xim hloov xim lossis kev ua haujlwm tsis zoo. Yog li ntawd, cov xim yuav tsum tau muab cia rau hauv ib qho chaw txias, lub teeb-pov thawj warehouse.
Siv cov thawv tsaus: Qee cov xim A1 epoxy tau ntim rau hauv cov xim tsaus kom txo tau cov duab. Thawj lub ntim yuav tsum khaws cia kom zoo thaum khaws cia.
4. Tsis txhob sawv ntsug ntev
Tig tsis tu ncua: Yog tias cov xim khaws cia ntev (ntau tshaj 6 lub hlis), lub thoob xim yuav tsum muab tig los yog dov tsis tu ncua los tiv thaiv cov xim thiab resin los ntawm kev daws thiab stratifying.
Thawj-hauv-thawj-tawm txoj cai: Siv nyob rau hauv kev txiav txim ntawm hnub tsim khoom kom tsis txhob xim tsis ua hauj lwm vim tas sij hawm.
5. Nyob deb ntawm cov tshuaj lom neeg
Cia nyias nyias: Cov xim yuav tsum tau khaws cia kom deb ntawm cov tshuaj xws li acids, alkalis, thiab cov kuab tshuaj organic kom tsis txhob muaj tshuaj lom neeg uas ua rau muaj kev puas tsuaj.
Kev ua pa zoo: Qhov chaw cia khoom yuav tsum tau ua pa kom tsis txhob muaj cov khoom tawg yooj yim uas cuam tshuam rau qhov zoo ntawm cov xim.
Cov hauv qab no yog cov duab ntim ntawm SML Yeeb Nkab & fittings hauv DINSEN warehouse:
2. Kev tshuaj xyuas qhov ua rau cov yeeb nkab hlau cam khwb cia xim lightening lossis discoloration
Yog tias cov xim A1 epoxy tsis khaws cia kom zoo, cov yeeb nkab hlau cam tom qab pleev xim yuav muaj teeb meem xws li lightening, yellowing, whitishness, los yog ib nrab discoloration. Cov laj thawj tseem ceeb suav nrog:
1. Kub kub ua rau resin aging
Phenomenon: Cov xim ntawm cov xim hloov daj lossis tsaus dua tom qab pleev xim.
Ua rau: Nyob rau hauv ib puag ncig kub, epoxy resin yuav oxidize los yog cross-link, ua rau cov xim xim hloov. Tom qab tha xim, cov xim ntawm cov cam khwb cia hlau yeeb nkab yuav plam nws cov xim qub vim cov resin aging.
2. Moisture intrusion ua rau kev kho tsis zoo
Phenomenon: Dawb pos huab, whitening los yog tsis sib xws xim tshwm nyob rau saum npoo ntawm txheej.
Yog vim li cas: Lub thawv xim tsis nruj nruj thaum khaws cia. Tom qab noo noo nkag mus, nws reacts nrog tus neeg sawv cev kho kom tsim amine ntsev los yog carbon dioxide, uas ua rau pos huab tsis xws luag nyob rau saum npoo ntawm txheej, cuam tshuam rau cov xim hlau luster ntawm cam khwb cia hlau yeeb nkab.
3. Photodegradation tshwm sim los ntawm ultraviolet hluav taws xob
Phenomenon: Cov xim xim yuav sib dua los yog xim sib txawv tshwm sim.
Ua rau: Cov kab hluav taws xob ultraviolet nyob rau hauv lub hnub yuav rhuav tshem cov xim thiab cov qauv resin hauv cov xim, ua rau cov xim ntawm cov yeeb nkab hlau cam khwb cia tom qab pleev xim kom maj mam ploj lossis tsis muaj xim.
4. Solvent volatilization lossis paug
Phenomenon: Particles, shrinkage qhov los yog discoloration tshwm nyob rau hauv cov xim zaj duab xis.
Ua rau: Cov kuab tshuaj volatilization ntau dhau ua rau cov xim viscosity siab dhau, thiab cov atomization tsis zoo thaum lub sij hawm txau ua rau cov xim tsis sib xws.
Cov impurities (xws li plua plav thiab roj) sib xyaw hauv lub sijhawm cia yuav cuam tshuam rau cov yeeb yaj kiab tsim cov xim ntawm cov xim thiab ua rau muaj qhov tsis xws luag ntawm cov yeeb nkab hlau cam khwb cia.
3. Yuav ua li cas kom tsis txhob muaj xim txawv txav ntawm cam khwb cia hlau yeeb nkab tom qab tha xim
Ua raws li cov txheej txheem khaws cia nruj me ntsis thiab xyuas kom meej qhov kev xav tau ntawm qhov kub thiab txias, av noo, tiv thaiv lub teeb, thiab lwm yam.Kev cia tsis raug ntawm cov yeeb nkab hlau cam khwb cia nrog A1 epoxy xim yuav ua rau cov xim sib dua, daj lossis tsis muaj xim. Los ntawm kev tswj hwm qhov kub thiab txias, av noo, tiv thaiv lub teeb thiab lwm yam kev mob, thiab tsis tu ncua xyuas cov xwm txheej pt, txheej txheej tsis zoo los ntawm cov teeb meem khaws cia tuaj yeem zam tau zoo, kom ntseeg tau tias kev zoo nkauj thiab kev tiv thaiv kev ua haujlwm ntawm cov cam khwb cia hlau yeeb nkab yog qhov zoo tshaj plaws.
