Txhawm rau kom qhov kub thiab txias zoo dua, lub tshuab hluav taws xob tracing qhov muag yuav tsum tau siv ib txheej ntawm pob zeb wool kom cov cua sov.Niaj hnub no, cia peb hais tias yog vim li cas pob zeb wool siv es tsis txhob asbestos los yog lwm yam rwb thaiv tsev.
Pob zeb wool originated nyob rau hauv Hawaii.Tom qab thawj volcanic eruption ntawm cov kob ntawm Hawaii, cov neeg nyob hauv cov kob pom wisps ntawm melted mos pob zeb nyob rau hauv av, uas yog lub pob zeb wool fiber pom los ntawm cov tib neeg thaum ntxov.Tom qab ntawd, tib neeg simulated cov txheej txheem ntawm volcanic eruption nyob rau hauv Hawaii, siv high-zoo basalt, dolomite thiab lwm yam raw cov ntaub ntawv raws li lub ntsiab raw cov ntaub ntawv, tom qab melting ntawm kub siab tshaj 1450 ℃, cov fiber ntau yog tsim los ntawm high-speed centrifugation nrog. thoob ntiaj teb advanced plaub-axis centrifuge.Nyob rau tib lub sijhawm, ib qho nyiaj ntawm cov ntaub ntawv pov thawj, cov roj av pov thawj thiab cov neeg sawv cev hydrophobic tau txau rau hauv cov paj rwb, sau los ntawm cov paj rwb los ntawm cov txheej txheem pendulum, thiab tom qab ntawd solidified tom qab cov paj rwb tau kis los ntawm peb-dimensional txoj kev txiav. , tsim pob zeb wool khoom ntawm txawv specifications thiab siv.
Pob zeb cov khoom lag luam raug lees paub tias yog cov khoom siv hluav taws xob tseem ceeb ntawm "thib tsib lub zog" nyob hauv lub ntiaj teb vim nws cov khoom siv hluav taws xob zoo thiab thermal rwb thaiv tsev.Hauv kev tsim kho, txhua qhov kev siv 1 tuj ntawm pob zeb wool khoom rau thermal rwb thaiv tsev tuaj yeem txuag tau tsawg kawg 1 tuj roj zog hauv ib xyoos, uas yog nyob rau hauv txoj kab nrog kev tiv thaiv ib puag ncig ntawm cov ntaub pua plag, kev txuag hluav taws xob thiab txo qis emission.Yog li ntawd, pob zeb wool yog siv los ua lub tsev zoo tshaj plaws thermal rwb thaiv tsev khoom.Nws tuaj yeem hais tias pob zeb wool yuav siv dav rau yav tom ntej, thiab kev cia siab ntawm kev lag luam kuj zoo siab heev.Nyob rau hauv cov nqe lus ntawm kev txuag hluav taws xob ntawm lub qhov muag ntxhua khaub ncaws, nws cov kev ua tau zoo dua li lwm yam khoom.
yam ntxwv:
1. Kev tiv thaiv ib puag ncig thiab kev huv, tsis muaj teeb meem dej zais, tsis muaj ntxhiab tsw, tsis muaj teeb meem, tuaj yeem ua kom cov dej ntshiab;
2. Lead dawb, tsis muaj teeb meem rau tib neeg lub cev;
3. Hnav tsis kam;
4. Acid thiab alkali tsis kam;
5. Tsawg kub tsis kam;
6. Lub cev ruaj khov thiab ruaj khov.
