Fiberglass yog cov khoom siv tsis zoo uas tsis yog xim hlau uas tuaj yeem hloov tau hlau, nrog kev ua haujlwm zoo, thiab tau siv dav hauv ntau lub teb chaws kev lag luam, ntawm cov khoom siv hluav taws xob, kev thauj mus los thiab kev tsim kho yog peb lub ntsiab kev siv.Nrog rau kev cia siab zoo rau kev txhim kho, cov tuam txhab fiberglass loj tau tsom mus rau kev ua haujlwm siab thiab kev ua kom zoo ntawm fiberglass.

1 、 Txhais ntawm fiberglass
Fiberglass yog ib qho kev xaiv rau hlau thiab kev ua tau zoo ntawm cov khoom siv tsis muaj hlau tsis muaj hlau, yog cov ntxhia hauv ntuj nrog silica ua cov khoom siv tseem ceeb, ntxiv cov hlau oxide ntxhia raw cov ntaub ntawv.Nws qhov kev npaj yog molten ntawm qhov kub thiab txias, kos nyob rau hauv qhov kev txiav txim ntawm high-speed rub quab yuam mus rau lub xeev molten ntawm lub khob ncab rau hauv fibers.
Fiberglass monofilament txoj kab uas hla los ntawm ob peb microns mus rau ntau tshaj nees nkaum microns, sib npaug rau cov plaub hau ntawm 1/20-1/5, zoo nkauj fiber ntau tsis ncaj ncees yog ntau pua lossis ntau txhiab tus monofilament muaj pes tsawg leeg.

2, Cov yam ntxwv ntawm fiberglass
Lub melting point ntawm iav fiber yog 680 ℃, boiling point yog 1000 ℃, ceev yog 2.4 ~ 2.7g / cm3.Tensile lub zog nyob rau hauv lub xeev tus qauv yog 6.3 ~ 6.9g / d, ntub lub xeev yog 5.4 ~ 5.8g / d.
Txhim kho rigidity thiab hardness:qhov nce ntawm fiberglass tuaj yeem txhim kho lub zog thiab rigidity ntawm cov yas, tab sis tib lub yas toughness yuav txo.
Zoo toughness, tsis yooj yim rau deformation, zoo cuam tshuam kuj:fiberglass daim ntawv thov txheej txheem, tej zaum vim stretching los yog lub ntiajteb txawj nqus thiab lwm yam cuam tshuam deformation, tab sis vim nws zoo toughness, nyob rau hauv ntau yam ntawm quab yuam yuav rov qab mus rau qhov qub, kev siv ntawm high efficiency.

Zoo kub tsis kam:fiberglass yog ib qho inorganic fiber, thermal conductivity tsawg heev, yuav tsis ua rau combustion, thiab kub kuj thiab zoo.Nws feem ntau yog siv los ua cov cuab yeej hluav taws xob hauv kev tsim cov khoom siv, uas tuaj yeem txo ntau yam kev nyab xeeb.
Kev nqus dej noo:Kev nqus dej ntawm fiberglass yog 1/20 ~ 1/10 ntawm ntuj thiab hluavtaws fibers.Kev nqus dej yog cuam tshuam nrog cov iav muaj pes tsawg leeg, thiab cov dej nqus ntawm cov fiber ntau uas tsis yog alkali yog qhov tsawg tshaj plaws, thiab cov dej nqus ntawm cov alkali fiber ntau yog qhov loj tshaj.
Brittleness:fiberglass yog nkig dua lwm cov fibers, tsis hnav-tiv taus thiab yooj yim tawg.Tab sis thaum lub fiber inch me me mus rau 3.8μm los yog tsawg dua, cov fiber ntau thiab nws cov khoom muaj softness zoo.
Zoo corrosion kuj:Cov tshuaj ruaj khov ntawm fiberglass nyob ntawm nws cov tshuaj muaj pes tsawg leeg, qhov nruab nrab, qhov kub thiab txias, thiab lwm yam. Fiberglass muaj kev tiv thaiv zoo rau cov tshuaj corrosive xws li acids thiab alkalis, zoo li tsis cuam tshuam los ntawm cov kuab tshuaj organic, thiab ruaj khov rau feem ntau inorganic. tshuaj sib xyaw.
