Peb theem ntawm Epoxy hmoov txheej

1. Ua kua - Lub sijhawm ua haujlwm
Lub sijhawm ua haujlwm (tseem hu ua lub neej lub lauj kaub) yog ib feem ntawm lub sijhawm kho thaum lub sijhawm, tom qab sib tov, cov khoom sib xyaw / tawv tawv tseem ua kua thiab ua haujlwm tau thiab tsim nyog rau daim ntawv thov. Txhawm rau kom ntseeg tau tias muaj kev sib raug zoo, txhua daim ntawv thov thiab kev ua haujlwm yuav tsum tau ua nyob rau hauv lub sijhawm ua haujlwm kho.
2. Gel - Nkag mus rau qhov kho
Cov sib tov pib nkag mus rau theem kho (tseem hu ua lub hnub nyoog laus) qhov twg nws pib gel lossis "snap". Lub epoxy yuav tsis tuaj yeem ua haujlwm tau ntev thiab yuav poob nws cov tack. Nws yuav tsum tsis txhob cuam tshuam rau theem no. Nws yuav dhau los ua cov gel zoo li cov roj hmab tawv uas koj tuaj yeem nias nrog koj tus ntiv tes xoo.
Vim tias qhov sib tov tsuas yog kho tau qee qhov ntawm lub sijhawm no, epoxy tshiab tseem tuaj yeem sib xyaw ua ke rau nws, yog li nws tseem tuaj yeem sib cog lus lossis ua rau cov chaw tsis kho. Txawm li cas los xij, raws li kev sib xyaw ua kom zoo, cov peev txheej no txo ​​qis.
3. Khoom - Kho zaum kawg
Cov epoxy sib tov mus txog rau theem ntawm kev kho thiab solidification qhov twg nws tuaj yeem sanded thiab zoo li tus. Lub sijhawm no, koj tsis tuaj yeem nias nws nrog koj tus ntiv tes xoo. Lub sijhawm no, epoxy resin muaj li ntawm 90% ntawm nws qhov kawg cov tshuaj tiv thaiv lub zog, yog li koj tuaj yeem tshem tawm qhov kho clamp thiab tawm hauv chav sov rau ob peb hnub kom kho tau.
Lub sijhawm no, cov epoxy resin tshiab siv tsis tuaj yeem txuas nrog rau nws, vim tias epoxy saum npoo yuav tsum raug kho kom zoo, xws li polishing, kom tau txais kev sib txuas zoo ntawm lub zog.
Polyisocyanate
Cov kev siv tseem ceeb ntawm cov khoom sib xyaw polyisocyanate curing agents thiab lwm yam tshuaj tua kab mob yog cov xim, ua npuas ncauj, txheej, thiab lwm yam. Ntawm lawv, cov dej kaw-dispersible polyisocyanate curing tus neeg sawv cev kuj tuaj yeem siv nrog melamine assimilation tus neeg saib xyuas, siv melamine curing agent los txo cov nqi. thiab kaw dej-dispersible polyisocyanate curing tus neeg sawv cev los txhim kho kev ua haujlwm. Cov tiam ntawm polyisocyanates yog siv nyob rau hauv ob-tivthaiv polyurethane coatings, uas tau dhau los ua lub ntsiab technology nyob rau hauv ntau daim ntawv thov teb, xws li automotive kho xim, loj-scale tsheb xim, muaj xim, xim ntoo, xim yas, thiab lwm yam raws li lub zej zog them. Kev saib xyuas ntau dua rau kev tiv thaiv ib puag ncig, kev ua haujlwm siab kho cov neeg ua haujlwm uas tuaj yeem txo cov organic tsis muaj zog emissions, xws li dej-dispersible curing agents thiab low-viscosity curing agents, yuav yog lub hom phiaj ntawm kev txhim kho yav tom ntej. Raws li nws cov kev siv ntau, kev txhim kho yav tom ntej ntawm kev sib xyaw polyisocyanate curing agents yog qhov zoo.
Txoj kev loj hlob ntawm cov tshuaj tua kab mob yog ntau yam, ua haujlwm siab, nplaim hluav taws xob, tawv tawv, latent, txuag hluav taws xob, thiab tus phooj ywg ib puag ncig, thiab yuav tsum tau them nyiaj ntau rau kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.
