Cov txheej txheem synthesis ntawm epoxy hmoov txheej feem ntau suav nrog kev xaiv cov khoom siv raw, batching, sib tov, txau thiab lwm yam txuas.
1. Kev xaiv cov khoom siv raw
Epoxy resin yog cov khoom siv tseem ceeb ntawm epoxy hmoov txheej, thiab nws qhov zoo cuam tshuam ncaj qha rau kev ua haujlwm ntawm txheej. Yog li ntawd, kev saib xyuas yuav tsum tau them rau qhov sib piv ntawm qhov zoo thiab kev ua haujlwm zoo thaum xaiv. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau xaiv cov khoom siv raw khoom tsim nyog xws li curing agent, hnyav, additives, thiab lwm yam raws li cov ntawv thov sib txawv thiab kev siv ib puag ncig.
2. Batching
Thaum lub sij hawm batching txheej txheem, ntau yam raw khoom yuav tsum raug hnyav tawm raws li ib tug piv txwv thiab ntxiv rau cov khoom sib tov. Thaum lub sij hawm batching txheej txheem, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib xyaw ntawm impurities thiab tiam ntawm kev ua yuam kev los xyuas kom meej qhov zoo ntawm txheej.
3. Sib tov
Kev sib xyaw yog qhov txuas tseem ceeb hauv cov txheej txheem synthesis ntawm epoxy hmoov txheej. Kev xaiv thiab kev ua haujlwm ntawm cov khoom siv sib xyaw muaj qhov cuam tshuam tseem ceeb rau qhov zoo thiab kev ua haujlwm ntawm txheej txheej. Thaum lub sij hawm sib tov, cov khoom siv sib xyaw tsim nyog thiab kev ua haujlwm yuav tsum raug xaiv raws li qhov muaj pes tsawg leeg, kev faib ua feem thiab cov khoom ntawm txheej kom ntseeg tau tias sib xyaw ua ke.
4. Txau
Txau yog qhov txuas kawg ntawm epoxy hmoov txheej. Ua ntej txau, lub substrate yuav tsum tau kho saum npoo kom ntseeg tau qhov adhesion ntawm txheej rau substrate. Thaum lub sij hawm txau cov txheej txheem, yuav tsum tau them nyiaj mloog mus rau kev tswj tsis tau xws li txau thickness, txau nrug, txau ceev, nrog rau kev tu thiab tu cov cuab yeej txau kom zoo thiab ruaj khov ntawm txheej.
