Fiberglass yog ib yam khoom siv inorganic uas tsis yog hlau uas tuaj yeem hloov hlau, nrog kev ua tau zoo heev, thiab siv dav hauv ntau qhov chaw ntawm kev lag luam hauv tebchaws, ntawm cov khoom siv hluav taws xob, kev thauj mus los thiab kev tsim kho yog peb daim ntawv thov tseem ceeb. Nrog rau kev cia siab zoo rau kev txhim kho, cov tuam txhab fiberglass loj tab tom tsom mus rau kev ua tau zoo thiab kev ua haujlwm zoo ntawm fiberglass.
1, Kev txhais ntawm fiberglass
Fiberglass yog lwm txoj hauv kev hloov hlau thiab kev ua tau zoo ntawm cov khoom siv inorganic uas tsis yog hlau, yog cov khoom siv ntuj tsim nrog silica ua cov khoom siv tseem ceeb, ntxiv cov khoom siv hlau oxide tshwj xeeb. Nws cov khoom npaj yog yaj ntawm qhov kub siab, rub los ntawm kev ua haujlwm ntawm lub zog rub ceev ceev rau lub xeev yaj ntawm lub iav ncab ua cov fibers.
Fiberglass monofilament txoj kab uas hla ntawm ob peb microns mus rau ntau tshaj nees nkaum microns, sib npaug rau cov plaub hau ntawm 1 / 20-1 / 5, cov khoom siv fiber zoo nkauj muaj ntau pua lossis txawm tias ntau txhiab monofilament sib xyaw.
2, Cov yam ntxwv ntawm fiberglass
Lub ntsiab lus yaj ntawm cov iav fiber yog 680 ℃, lub ntsiab lus kub yog 1000 ℃, qhov ceev yog 2.4 ~ 2.7g / cm3. Lub zog tensile hauv lub xeev txheem yog 6.3 ~ 6.9g / d, lub xeev ntub yog 5.4 ~ 5.8g / d.
Txhim kho qhov rigidity thiab hardness:qhov nce ntawm fiberglass tuaj yeem txhim kho lub zog thiab rigidity ntawm yas, tab sis tib lub yas toughness yuav txo qis.
Zoo toughness, tsis yooj yim rau deformation, zoo cuam tshuam tsis kam:Cov txheej txheem thov fiberglass, qee zaum vim yog ncab lossis lub ntiajteb txawj nqus thiab lwm yam kev cuam tshuam deformation, tab sis vim nws qhov zoo toughness, nyob rau hauv qhov ntau ntawm lub zog yuav raug rov qab los rau qhov qub, kev siv cov khoom siv siab.
Kev tiv taus cua sov zoo:fiberglass yog ib qho inorganic fiber, thermal conductivity yog me me heev, yuav tsis ua rau combustion, thiab kub tsis kam thiab zoo. Nws feem ntau yog siv ua lub cuab yeej hluav taws kub hauv kev tsim cov ntaub ntawv, uas tuaj yeem txo ntau yam kev phom sij kev nyab xeeb.
Kev nqus dej noo:Qhov nqus dej ntawm fiberglass yog 1/20 ~ 1/10 ntawm cov fibers ntuj thiab cov khoom siv hluavtaws. Kev nqus dej muaj feem cuam tshuam nrog cov iav sib xyaw, thiab kev nqus dej ntawm cov fiber tsis-alkali yog qhov tsawg tshaj plaws, thiab kev nqus dej ntawm cov fiber alkali siab yog qhov loj tshaj plaws.
Kev tawg yooj yim:Fiberglass yog brittle dua li lwm cov fibers, tsis hnav-resistant thiab yooj yim tawg. Tab sis thaum lub fiber txoj kab uas hla yog me me rau 3.8μm lossis tsawg dua, cov fiber thiab nws cov khoom muaj softness zoo.
Kev tiv thaiv corrosion zoo:Qhov kev ruaj khov ntawm cov tshuaj fiberglass nyob ntawm nws cov tshuaj lom neeg, qhov xwm txheej ntawm cov khoom nruab nrab, kub thiab siab, thiab lwm yam. Fiberglass muaj kev tiv thaiv zoo rau cov tshuaj corrosive xws li cov kua qaub thiab alkalis, tsis cuam tshuam los ntawm cov organic solvents, thiab ruaj khov rau feem ntau cov inorganic compounds.
