Epoxy resin yog cov khoom siv thermosetting polymer uas muaj cov resin, curing agent, thiab lwm yam khoom siv ntxiv. Nws muaj cov khoom siv hluav taws xob zoo heev, tshuaj lom neeg ua haujlwm, thiab lub zog txhua yam, thiab siv dav hauv cov txheej txheem, cov nplaum, cov ntaub ntawv sib xyaw, cov ntim hluav taws xob, thiab lwm yam.
I. Txoj Kev Thov
Kev siv cov epoxy cob ncaj qha cuam tshuam rau kev ua haujlwm kawg thiab feem ntau ua raws li cov kauj ruam no:
Deg Pretreatment: Xyuas kom lub substrate qhuav, huv si, thiab tsis muaj roj, plua plav, thiab lwm yam., kom lav adhesion.
Kev sib xyaw ua ke: Ua kom raug qhov hnyav ntawm epoxy resin thiab kho tus neeg sawv cev raws li qhov piv txwv, thiab do kom huv si kom txog thaum homogeneous, txo qhov tsim ntawm huab cua npuas thaum ua haujlwm.
Daim ntawv thov: Thov los yog ncuav qhov sib tov sib npaug mus rau lub substrate nto. Kev txhaj tshuaj molding, lamination, thiab lwm yam txheej txheem kuj tseem siv tau.
Cov txheej txheem kho: Khaws qhov sib tov ntawm qhov ntsuas kub kom haum rau lub sijhawm tshwj xeeb kom tso cai rau lub kaw lus hla tag nrho -txuas thiab kho, ua tiav qhov kev tsim qauv.
Tom qab-kev kho mob: Ua cov kev kho saum npoo xws li xuab zeb thiab polishing raws li xav tau.
II. Cov ntsiab lus tseem ceeb ntawm kev sib xyaw Cov kev ua tau zoo ntawm epoxy resin systems yog ze ze rau lawv qhov sib xyaw:
Qhov piv ntawm epoxy resin rau curing tus neeg sawv cev yog feem ntau 100:10 txog 100:30. Qhov sib piv tshwj xeeb yuav tsum tau txiav txim siab raws li cov lus qhia ntawm cov khoom thiab cov kev xav tau ntawm kev ua haujlwm.
Yog tias yuav tsum tau hloov kho viscosity, qhov tsim nyog ntawm reactive lossis inactive diluent tuaj yeem ntxiv, feem ntau pom zoo kom tsis pub tshaj 10% ntawm tag nrho cov resin ntim.
Kev sib tov yuav tsum tsis tu ncua thiab ua raws li cov txheej txheem cov lus qhia kom tsis txhob muaj kev kho tsis zoo lossis kev ua haujlwm tsis zoo.
III. Insulation Properties Epoxy resin muaj cov khoom siv hluav taws xob zoo heev. Cov pawg polar hauv nws cov qauv molecular tuaj yeem khi cov cab kuj thiab txo cov conductivity. Ua ke nrog nws lub zog txhua yam thiab ib puag ncig tiv thaiv, cov khoom siv no tsim nyog rau cov txheej txheem insulating, ntim hluav taws xob, thiab cov khoom siv hluav taws xob txhawb nqa, txhim kho cov cuab yeej kev nyab xeeb thiab kev ntseeg tau ntev ntev.
Hauv cov ntsiab lus, epoxy resin yog ntau yam thiab dav siv cov khoom siv polymer. Los ntawm cov txheej txheem kev ua haujlwm thiab kev sib xyaw ntawm kev tshawb fawb, nws cov txiaj ntsig zoo hauv kev rwb thaiv tsev, kev tiv thaiv, thiab kev txhawb nqa tuaj yeem siv tag nrho.
