Cov ntaub ntawv fiberglass yog ib qho khoom siv tsis sib xws uas tuaj yeem hloov cov hlau, thiab siv tau dav hauv kev lag luam hauv tebchaws, thiab yog kev thauj mus los thiab kev tsim kho yog peb daim ntawv thov tseem ceeb. Nrog rau cov kev npaj siab zoo rau kev txhim kho, cov tuam txhab fiberglass loj yog tsom rau kev ua tau zoo thiab ua haujlwm zoo ntawm fiberglass.
1, cov ntsiab lus ntawm fiberglass
Cov ntaub ntawv fiberglass yog lwm txoj hauv kev rau cov hlau thiab kev ua tau zoo ntawm cov ntaub ntawv me me uas tsis muaj hlau, yog cov khoom siv hlau loj, yog cov hlau loj cov khoom nyoos. Tej kev npaj yog molten ntawm qhov kub siab, kos nyob rau hauv qhov kev txiav txim ntawm kev siv ceev rub tawm rau lub xeev molten ntawm cov iav ncab rau hauv cov fibers.
Fiberglass monofilament txoj taub los ntawm ob peb microns rau ntau dua nees nkaum ntawm 1 / 20-1 / 5, zoo nkauj kos duab fiber ntau heev.
2, Cov yam ntxwv ntawm fiberglass
Lub ntsiab lus melting ntawm cov iav fiber yog 680 ℃, boiling taw tes yog 1000, ntom ntawj yog 2.4 ~ 2.7g / cm3. Tensile lub zog hauv lub xeev Txheem yog 6.3 ~ 6.9G / D, Lub xeev lub xeev yog 5.4 ~ 5.8g / d.
Txhim kho rigidity thiab hardness:Qhov nce ntawm fiberglass tuaj yeem txhim kho lub zog thiab cov yas ntawm yas, tab sis cov yas tawv tawv yuav tsawg.
Zoo toughness, tsis yooj yim rau deformation, zoo cuam tshuam kev tiv thaiv:Cov txheej txheem fiberglass kev thov, qee zaum vim muaj kev ncab lossis kev sib tsoo thiab vim nws qhov kev cuam tshuam zoo, tab sis vim nws cov kev cuam tshuam zoo, nyob rau hauv cov kev quab yuam zoo, hauv kev siv dag zog rau tus thawj, kev siv cov kev ua haujlwm siab.
Cov cua sov zoo:Fiberglass yog ib qho inorganic fiber ntau, thermal conductivity yog qhov me me, yuav tsis ua rau kev sib tw, thiab kub tsis kam thiab zoo. Nws feem ntau yog siv los ua cov cuab yeej tua hluav taws hauv kev tsim cov ntaub ntawv, uas tuaj yeem txo ntau cov phom sij nyab xeeb.
Kev nqus dej noo:Cov dej nqus ntawm cov fiberglass yog 1/3 ~ 1/10 ntawm ntuj thiab hluavtaws fibers. Kev nqus dej cuam tshuam nrog cov iav muaj feem cuam tshuam, thiab cov dej nqus ntawm cov dej tsis-alkali yog qhov tsawg tshaj plaws, thiab cov dej nqus ntawm high alkali fiber yog qhov loj tshaj plaws.
Brittleness:Fiberglass tau ntau dua nkig dua li lwm cov fibers, tsis hnav-resistant thiab yooj yim tawg. Tab sis thaum lub cheeb tsam fiber ntau yog me me rau 3.8μm lossis tsawg dua, cov fiber ntau thiab nws cov khoom muaj kev muag khoom zoo.
Zoo corrosion resistance:Cov tshuaj ruaj khov ntawm fiberglass nyob ntawm nws cov tshuaj lom neeg muaj cov tshuaj lom neeg, thiab cov tshuaj lom neeg zoo nkauj, thiab yog qhov ruaj khov rau feem ntau inorganic compounds.
