Kev Taw Qhia
Hauv kev ua tshuaj lom neeg, cov khoom siv hauv tsev, lub zog tshiab, tshuaj thiab cov khoom noj khoom haus, lub tshuab nqus tsev uas muaj zog heev ntawm cov hlau tsis xeb tau dhau los ua cov khoom siv "tus qauv" rau kev sib tov thiab sib kis cov khoom siv viscosity siab. Txawm tias koj tab tom tsim cov khoom siv silicone sealant, lithium battery slurry, lossis cov nplaum hluav taws xob, cov khoom siv no ua lub luag haujlwm tseem ceeb.
Nws lub ntsiab lus tseem ceeb yog peb yam:
Cov ntawv thov kev sib kis ceev ceev: Siv tau rau cov khoom siv viscosity siab heev txog li ntau lab centipoise (cps), rhuav cov hmoov sib xyaw ua ke mus rau micron lossis txawm tias nanometer kom sib kis tau zoo ib yam.
Kev tiv thaiv corrosion: Kev tsim kho hlau stainless tiv taus cov kua qaub, alkalis thiab cov tshuaj lom neeg, ua kom muaj kev ua haujlwm ruaj khov mus sij hawm ntev.
Qhov zoo ntawm kev siv lub tshuab nqus tsev kom tshem cov pa roj tawm: Kev rho tawm cov pa roj tawm tas li thaum lub sijhawm sib tov tshem tawm cov npuas cua, ua kom cov khoom kawg ntom ntom thiab lub zog nplaum.
Txawm li cas los xij, vim muaj ntau tus qauv thiab ntau yam kev qhia tshwj xeeb sib txawv, ntau tus neeg yuav khoom poob rau hauv cov teeb meem zoo sib xws: piv cov nqi tsis pom kev thaum tsis quav ntsej txog cov txheej txheem , lossis raug ntxias los ntawm kev muag khoom kom xaiv cov khoom siv loj thiab tsis tsim nyog. Qhov tshwm sim feem ntau yog lub tshuab uas tuaj txog ntawm lub Hoobkas tab sis ua pov thawj tias "nyuaj rau siv", "kim rau khiav", lossis "tsis sib xws".
Phau ntawv qhia no yuav coj koj mus rau 4 qhov kev xaiv tseem ceeb , ua ke nrog kev xaiv tshwj xeeb rau kev lag luam , pab koj nrhiav tus qauv zoo hauv 3 feeb xwb.
1. Plaub Qhov Loj Xaiv Qhov Tseem Ceeb (Yuav Tsum Tau Tshawb Xyuas)
Kev xaiv tsis yog hais txog kev sib piv cov lej ntawm daim ntawv qhia tshwj xeeb - nws yog hais txog kev sib phim cov lej ntawd rau koj cov kev xav tau tiag tiag . Tsis txhob hla ib qho ntawm plaub qhov ntsuas no.
