Epoxy resin kav yog siv dav, nrog rau qhov zoo thiab qhov tsis zoo

Nyob rau hauv lub tsev tiv thaiv hluav taws, lub epoxy resin composite lub teeb yeeb nkab muaj ib tug pivotal txoj hauj lwm. Lub epoxy resin lub teeb yeeb nkab yuav tsum tau siv nyob rau hauv cov hluav taws tua hluav taws, thiab nws tau maj mam hloov cov galvanized steel yeeb nkab. Lub epoxy resin raj yog cov khoom siv tseem ceeb ntawm epoxy resin lub teeb raj, siv cov hmoov yas ua cov khoom siv txheej, thiab cov txheej yas yog yaj-coated ntawm nws sab hauv. Sab nrauv yog yaj-coated nrog ib txheej ntawm cov yas txheej los yog lwm yam khoom siv los tiv thaiv corrosion txheej ntawm cov khoom yas sib xyaw. Polyethylene-coated steel kav thiab epoxy-coated steel kav tau muab faib ua ob hom steel kav raws li cov khoom sib txawv hauv txheej txheej.

Txawm hais tias kev siv cov kav dej epoxy resin hauv lub tsev tiv thaiv hluav taws tau nce ntau, qee qhov nws tsis tuaj yeem tsis quav ntsej. Ib qho ntawm feem ntau yog cov huab cua tsis zoo, vim tias epoxy resin feem ntau muaj cov keyboards uas muaj ntxhiab tsw qab, thiab cov khoom kho tau raug degraded thiab tawg tom qab raug tshav ntuj. Yog li, cov khoom siv dav dav bisphenol A epoxy resin kho tau yooj yim kom raug tshav ntuj sab nraum zoov. Nws poob nws cov luster thiab maj mam chalks, yog li nws tsis haum rau sab nraum zoov topcoats. Tsis tas li ntawd, epoxy resin muaj qhov ua haujlwm tsis zoo ntawm qhov kub thiab txias, thiab feem ntau yuav tsum tau kho siab tshaj 10 degrees Celsius. Yog tias nws qis dua qhov ntsuas kub no, nws yuav tsis yooj yim rau kev tsim cov khoom loj.
