Dab tsi yog cov ntawv txiav thiab cov cores dawb?
Ob qho tib si txiav thiab cov cores dawb yog feem ntau siv cov khoom siv, siv rau kev rwb thaiv tsev, sealing, thiab waterproofing. Txawm li cas los xij, lawv cov ntaub ntawv thiab cov yam ntxwv sib txawv.
Lub tshuab txiav yog ib daim ntawv nruj ua los ntawm cov ntaub ntawv fiber ntau, feem ntau muaj ntau hom fiber ntau, xws li asbestos, iav fiber, thiab carbon fiber. Nws cov yam ntxwv tseem ceeb yog kub kub ua hauj, corrosion kuj, thiab mechanical zog.
Ib tug dawb core, ntawm qhov tod tes, yog ib lub teeb yuag, fluffy core khoom muaj li ntawm inorganic fibers thiab mineral cov ntaub ntawv, kuj hu ua paj rwb dawb. Nws cov yam ntxwv tseem ceeb yog rwb thaiv tsev zoo, lub suab nqus, thiab hluav taws kub.
Dab tsi yog kev siv cov ntaub qhwv thiab cov cores dawb?
Vim lawv cov yam ntxwv sib txawv, cov ntawv txiav thiab cov cores dawb yog haum rau ntau qhov chaw thiab daim ntawv thov:
Cov ntaub ntawv txiav yog siv los ua sealing, rwb thaiv tsev, thiab cov ntaub ntawv txhawb nqa nyob rau hauv ib puag ncig hnyav xws li kub, siab, thiab tshuaj corrosion, xws li hauv petrochemical, fais fab, nkoj tsim, thiab kev lag luam tshuaj;
Cov cores dawb, ntawm qhov tod tes, yog tsim rau cov ntaub ntawv siv hauv kev tsim kho, metallurgy, thiab kev lag luam teeb rau phab ntsa, ru tsev, suab rwb thaiv tsev, suab nqus, thiab hluav taws kub.
Yuav xaiv cov khoom zoo li cas?
Thaum xaiv ntawm cov ntaub qhwv los yog cov cores dawb li rwb thaiv tsev, sealing, waterproofing, thiab suab rwb thaiv tsev cov ntaub ntawv, nws yog ib qhov tsim nyog yuav tau xav txog qhov tseeb daim ntawv thov tej yam kev mob thiab yuav tsum tau:
Rau cov ntawv thov uas yuav tsum tau muaj qhov kub thiab txias, kev tiv thaiv corrosion, thiab lub zog ua haujlwm siab, cov ntaub qhwv yuav tsum tau xaiv;
Rau cov ntawv thov uas xav tau kev tiv thaiv hluav taws, rwb thaiv tsev kub, thiab lub suab nqus, cov cores dawb yuav tsum nyiam dua.
Nyob rau tib lub sijhawm, yam xws li thickness, ntom, durability, thiab tus nqi yuav tsum tau txiav txim siab thaum xaiv cov ntaub ntawv kom tau raws li qhov xav tau tiag tiag.
