Kev kub siab tiv thaiv kub hnyiab tau hais txog cov khoom siv sealing uas tuaj yeem muaj kev sib khi tau zoo hauv ib puag ncig kub. Nws daim ntawv thov ntau yog dav heev, thiab nws yog dav siv nyob rau hauv ntau cov teb, aerospace, tsheb, hluav taws xob kev lag luam thiab lwm yam.
Ua ntej tshaj plaws, hauv teb ntawm aviation thiab aerospace, qhov siab-resistant sealing strips yog siv rau kev sib khi cov khoom kub xws li aer-engines, pob zeb tshuab, thiab cuaj hlis. Nyob rau hauv cov chaw ib puag ncig loj, yuav tsum muaj cov ntaub ntawv sib dhos, muaj kuab lom tiv thaiv, cov tshuaj lom neeg tiv taus nruj.
Qhov thib ob, hauv kev tsim tsheb tsheb, qhov kub-resistant sealing strips yog siv rau kev sib nraws tshuab hluav taws xob, cov tshuab cua txias, tshuab nqus, thiab tso tshuab. Cov khoom siv no yuav tsim kom muaj kev kub siab thaum lub sijhawm ntev-nrawm, thiab kub-resistant sealing cov hlua khi yog qhov yuav tsum tau rau kev sib tw thiab kev ntseeg tau ntawm lub tsheb.
Ib qho ntxiv, hauv cov khoom hluav taws xob ntawm cov khoom siv hluav taws xob, cov khoom siv kub-resistant sealing cov hlua yog xws li sandiconductor kev tsim khoom, optoelectronics, cov khoom siv hluav taws xob, thiab hluav taws xob khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob. Hauv cov teb no, cov ntaub ntawv sealing yog yuav tsum muaj qhov kub kub ua rau muaj kev kub siab, corrosion tsis kam, zoo thermal conductivity thiab lwm yam ntxwv.
Thaum kawg, hauv kev lag luam petrochemical, kub tiv taus cov kab txaij yog siv rau kev sib khi hauv cov roj kub thiab kev lag luam tshuaj. Nyob rau hauv cov chaw muaj zog heev, yuav tsum muaj cov ntaub ntawv ntawm cov yam ntxwv xws li corrosion tsis kam, hnav tsis kam, thiab kub tsis kam.
Nyob rau hauv luv luv, muaj kub tiv taus cov hlua khi muaj ntau cov kev siv. Nyob rau hauv cov chaw muaj kub heev uas muaj kub, thiab corrosion siab, thiab corrosion, salding cov ntaub ntawv ua lub luag haujlwm tseem ceeb los xyuas kom muaj kev nyab xeeb, kev ntseeg tau, thiab muaj peev xwm siv tau, thiab muaj cov khoom siv.
Cov txheej txheem styrofoam tuaj yeem siv rau kev sib khi ntawm cov khoom siv hluav taws xob, thiab cov khoom siv roj hmab, ntau yam nws yuav raug siv rau kev sib sau ua hluav taws xob. Hauv kev tshawb xav, polyurethane ua npuas ncauj ib daim tuaj yeem ua lub luag haujlwm hauv kev sib khi, thiab nplaim hluav taws xob, tab sis cov nyhuv tsis txaus siab tom qab ua haujlwm tiag tiag. Yog li dab tsi yog vim li cas rau cov nyhuv tsis zoo ntawm cov npuas dej?
Qhov tseeb, cov polyurethane ua npuas ncauj siv roj hmab sawb nyias muaj cov nyhuv waterproof thiab nyuab sib khi. Yog tias tus neeg teb xov tooj tsis tau paub txaus los sis kev ua haujlwm thev naus laus zis tsis tau ua haujlwm thaum lub sijhawm ua haujlwm tiag tiag, nws yuav ua rau cov polyurethane ua npuas dej roj hmab kom tsis muaj txiaj ntsig tom qab kho roj hmab tom qab kho roj hmab. Cov nyhuv waterproof zoo, lossis cov nyhuv tsis zoo. Tsis tas li ntawd, hauv kev ua haujlwm tiag, yog tias saum npoo yuav tsum tsis huv, cov nyhuv yuav ua tsis zoo tom qab kho cov nyhuv, thiab lub neej pabcuam yuav raug txo kom tsawg.
