Core Protection Varnish rau Roj Transformers
Core Protection Varnish for Oil Transformers yog cov kua roj vanish txheej tshwj xeeb tsim los tiv thaiv cov khoom tseem ceeb tshaj plaws hauv cov roj -immersed transformer: nws cov tub ntxhais sib nqus. Cov khoom no siv epoxy resin puag uas tau hloov kho nrog cov khoom siv tshwj xeeb thiab ua tiav siv cov txheej txheem tshwj xeeb. Core Protection Varnish rau Roj Transformers muab superior hluav taws xob rwb thaiv tsev, qhov tseem ceeb rau cov tub ntxhais efficiency. Nws tswj kom meej meej nrog huab cua zoo, muaj tus neeg siv- tus phooj ywg tsis tshua muaj viscosity rau daim ntawv thov yooj yim, kho ntawm qhov kub thiab txias, thiab ua haujlwm zoo, ua rau lub teeb ci, pob tshab zaj duab xis nrog lub zog nplaum tshwj xeeb.
Lub hom phiaj tseem ceeb ntawm cov khoom yog los tiv thaiv cov kev ntxhov siab tshwj xeeb ntawm lub tank transformer. Nws cov formulation yog pov thawj los tswj kev ncaj ncees thiab adhesion thaum lub sij hawm ntev - lub sij hawm, nruam immersion nyob rau hauv circulating transformer roj, tsis muaj cracking los yog tev. Qhov no tsom rua kev ruaj ntseg tsim cov Core Protection Varnish rau Roj Transformers raws li cov khoom tshwj xeeb thiab cov khoom tseem ceeb uas nws lub hom phiaj yog los xyuas kom lub sijhawm ntev -kev ua tau zoo thiab kev ntseeg siab ntawm cov roj- immersed transformer cores.

Cov yam ntxwv txheej txheem
Ua tib zoo ntxuav qhov saum npoo ntawm cov tub ntxhais hlau ua ntej siv cov txheej txheej insulating.
Siv qhov xav tau ntawm cov khoom A.
Ua tib zoo ua raws li A: B piv ntawm 2: 1 thaum ntxiv cov khoom B rau lub tov khoom uas muaj cov khoom A. Sib tov cov khoom A thiab B kom huv si ua ntej siv.
Lub neej lub lauj kaub: 30-40 feeb ntawm 25℃(100g sib tov). Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws, xyuas kom meej tias cov txheej txheem yog siv li ntawm 40 feeb ntawm kev sib xyaw ua ke. Txwv tsis pub, nws yuav cuam tshuam qhov kev xav thiab adhesion tom qab kho.
Kho cov xwm txheej: Nto qhuav hauv 4 teev ntawm 25 degree, kho tag nrho hauv 24 teev. Lub sij hawm kho yuav txawv nyob ntawm qhov kub thiab txias.

Txee Lub neej thiab kev cia khoom
Lub neej txee: 180 hnub. Tom qab lub txee lub neej, cov khoom yuav tsum dhau kev soj ntsuam ua ntej siv. Khaws rau hauv qhov dej - qhov cua, qhov chaw qhuav kom deb ntawm hluav taws.
Cov kev ceev faj
Lub sijhawm ua haujlwm rau cov khoom no yog 40-50 feeb. Thov npaj thiab siv tam sim ntawd. Tsis txhob nchuav cov khoom tsis siv rau hauv cov khoom tsis sib xyaw. Xyuas kom zoo sealing thaum lub sij hawm cia; txwv tsis pub, Cheebtsam B tuaj yeem ua rau tsis zoo thiab cuam tshuam rau cov khoom lag luam.
