Kev faib tawm ntawm cov khoom siv damping
Raws li cov qauv ntawm cov khoom, lub suab nqus cov khoom siv tau muab faib ua peb pawg: ntxeem tau, ua kom zoo nkauj, thiab cov qauv tshwj xeeb. Tam sim no, cov ntaub ntawv ntxeem tau lub suab yog qhov siv dav, feem ntau suav nrog cov organic fibers, inorganic fibers, inorganic foams thiab foams.
1. Organic fiber ntau suab haum khoom
Lub thaum ntxov cov organic fiber suab zoo rau cov khoom siv feem ntau hais txog cov nroj tsuag ntuj, uas muaj lub suab zoo kev coj ua hauv nruab nrab thiab qhov siab ntau, tab sis muaj kev ua haujlwm tsis zoo hauv cov hluav taws kub, tiv thaiv kev ua kom tsis muaj zog thiab cov pov thawj. Nrog txoj kev loj hlob sai ntawm cov hluavtaws hauv kev lag luam, cov kws tshawb nrhiav tau ua cov kev tshawb fawb txog cov khoom hluavtaws.
2. Inorganic fiber ntau lub suab mloog cov ntaub ntawv
Inorganic fiber ntau lub suab mloog cov ntaub ntawv tsuas yog xa mus rau ntuj lossis khoom neeg tsim cov khoom siv fiber ntau uas yog ua raws li cov khoom siv inorganic. Cov ntaub ntawv no tsis tsuas muaj lub suab zoo suab zoo tab sis yog lub teeb hauv qhov hnyav thiab tsis sib txuas, tab sis lawv tsis yooj yim rau nruab thiab ua paug ib puag ncig thiab yuav cuam tshuam rau lawv. Tib neeg kev noj qab haus huv. Tom qab, cov hlau fiber suab nqus cov ntaub ntawv nrog nplaim retardant, qhov kub tsis kam thiab siab zog muaj, thiab lub suab nqus kev ua tau zoo yog qhov zoo heev, tab sis tus nqi yog siab thiab cov txheej txheem yog qhov nyuaj.
3. Inorganic ua npuas ncauj suab nqus cov ntaub ntawv
Tam sim no, cov kws tshawb nrhiav tsuas yog tsom rau kev tshawb fawb ntawm cov iav ua npuas thiab ua npuas hlau. Cov iav ua npuas yog lub teeb, tsis-xeb, tsis kub, tsis muaj ntxhiab, thiab yooj yim rau kev tsim kho. Nws cov porosity tuaj yeem ncav cuag ntau dua 85%, tab sis cov txheej txheem tsis tau zoo tswj thiab tus nqi siab. Ua npuas ncauj hlau yog ib yam tshiab ntawm cov khoom ntxeem tau, feem ntau tshawb fawb txog txhuas ua npuas ncauj thiab nws cov khoom siv alloys. Tom qab txau ua npuas, ntau cov npuas tsim nyob sab hauv, thiab muab faib rau hauv ntu hlau txuas ntxiv los tsim cov txheej txheem pore.
4. Ua npuas ncauj yas suab zoo rau kev nqus khoom
Foamed yas suab zoo nkauj cov khoom siv feem ntau yog hais txog ib hom khaub-ncaws nyias, lub suab nqus, kub insulating thiab nplaim taws rov qab ua los ntawm ntau cov ntaub ntawv, ntxiv me ntsis foaming tus neeg sawv cev, catalyst, stabilizer thiab lwm yam khoom siv pabcuam. Corrosion-resistant thiab poob siab-cov ntaub ntawv tau siv dav hauv polyurethane ua npuas ncauj suab nqus cov ntaub ntawv, tab sis lawv lub zog yog tsawg thiab tsis yooj yim rau siv.
