Fiberglass yog dab tsi?

Cov ntsiab lus ntawm cov ntaub ntawv

Fiberglass, hu ua "Fiberglass", yog cov khoom siv tshiab rau kev txhawb nqa thiab cov khoom siv hlau hloov. Txoj kab uas hla ntawm nws cov monofilament yog ob peb microns rau ntau tshaj 20 microns, uas yog sib npaug rau 1/20-1/5 ntawm cov plaub hau, thiab txhua pob ntawm fiber ntau precursors yog tsim los ntawm ntau pua lossis ntau txhiab tus monofilaments.

Cov fiberglass feem ntau yog siv los ua cov khoom siv ntxiv ntawm cov khoom sib xyaw, hluav taws xob rwb thaiv tsev thiab cov ntaub ntawv rwb thaiv tsev kub, substrate thiab lwm yam.
Thaum fiberglass siv los ua cov khoom siv ntxiv rau cov yas, qhov loj tshaj plaws yog nws lub zog tensile siab. Lub zog tensile yog 6.3 ~ 6.9 g / d nyob rau hauv lub xeev txheem thiab 5.4 ~ 5.8 g / d nyob rau hauv ntub dej. Qhov ceev 2.54g / cm3. Nws muaj qhov ua kom sov zoo thiab tsis muaj qhov cuam tshuam rau lub zog thaum kub txog 300 degree. Nws muaj cov rwb thaiv tsev zoo heev thiab yog cov khoom siv hluav taws xob zoo heev. Nws kuj tseem siv rau hauv cov khoom siv hluav taws xob rwb thaiv tsev thiab cov ntaub thaiv hluav taws kub. Feem ntau tsuas yog corroded los ntawm concentrated alkali, hydrofluoric acid thiab concentrated phosphoric acid.

Cov txheej txheem ntau lawm

Cov txheej txheem fiberglass ntau lawm yog grind thiab homogenize pyrophyllite thiab lwm yam raw cov ntaub ntawv, ncaj qha yaj lawv nyob rau hauv ib tug siab - kub kiln los ua iav kua, thiab ces kos lawv. Lub tshuab nqus hlau yog cov cuab yeej tseem ceeb rau iav fiber ntau txoj kev, thiab nws yog lub tshuab rau kos molten iav rau hauv hlau. Lub iav molten ntws los ntawm cov phaj bushing, yog ncab ntawm kev kub ceev los ntawm lub tshuab nqus hlau, thiab raug mob rau hauv cov duab hauv ib qho kev taw qhia. Tom qab ziab thiab interlacing tom qab, yuav muaj cov khoom siv fiberglass tawv heev.

Khoom siv

qhov zoo:

Fiberglass muaj cov yam ntxwv uas tsis yog -combustibility, corrosion kuj, rwb thaiv tsev kub, suab rwb thaiv tsev, siab tensile zog, thiab zoo hluav taws xob rwb thaiv tsev. Nws yog dav siv thiab muaj kev siv dav hauv kev tsim kho, tsheb, nkoj, cov kav dej tshuaj, kev tsheb ciav hlau, thiab cua zog thov kev cia siab.

Cov ntaub ntawv thov

Lub tsev façade modules yog ua los ntawm cov cement dawb thiab fiberglass, thiab lwm yam.
