Crepe Ntawv raj rau Transformers Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob
Lub insulating crepe raj tsim los ntawm insulating crepe raj tsis siv neeg tshuab muaj qhov zoo uas phau ntawv thiab semi-automatic tshuab tsis muaj txhua.Raws li rau tib txoj kab uas hla thiab tawm txoj kab uas hla, raws li tus qauv tsim ntawm lub transformer, qhov siab dua tus naj npawb ntawm cov lem yog, qhov zoo ntawm rwb thaiv tsev yuav zoo dua.Lub caij no, qhov ntau nruj nws yog qhwv, qhov siab dua nws elasticity, yooj thiab khoov kuj yuav.Raws li, nrog rau tib yam specifications thiab tib lub xov tooj ntawm daim, tes-dov crepe raj yog xoob vim muaj tsawg txheej txheej thiab qhov hnyav ntawm nws cov khoom tiav tsuas yog ib nrab ntawm cov khoom tsis siv neeg.Nyob rau tib lub sijhawm, tes dov crepe raj tsis muaj qhov hloov pauv thiab lub zog txhua.
Peb lub Hoobkas tau tshawb fawb thiab tsim cov kua nplaum ua tiav.Tom qab ntau qhov kev txhim kho, nws yog qhov loj dua.Peb lub Hoobkas txais cov qib siab ntshiab resin, cov tshuaj tiv thaiv kub thiab kev tsim khoom zoo yam tsis muaj impurities thiab thaum kawg, PVA-raws li hluav taws xob rwb thaiv tsev kua nplaum nrog cov purity siab thiab cov khoom siv tau zoo yog tsim, uas muaj zog heev.Txawm hais tias lawv muaj zog distorted, ntaus rau ntawm cov khoom tawv, los yog torn destructively.Thiab cov khoom zoo li no tsis muaj kev puas tsuaj rau lub rwb thaiv tsev transformer.Qhov tshwj xeeb PVA kua nplaum no tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom siv txawv teb chaws.
