Fiberglass: Cov Khoom, Cov Txheej Txheem, Cov Lag Luam

Cov khoom sib xyaw thiab cov yam ntxwv ntawm fiberglass
Cov khoom tseem ceeb yog silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, thiab lwm yam. Raws li qhov ntau ntawm cov alkali ntsiab lus hauv lub khob, nws tuaj yeem faib ua:
①,fiberglass uas tsis yog alkaline(sodium oxide 0% ~ 2%, yog ib lub iav borosilicate txhuas)
②, nruab nrab alkali fiberglass (sodium oxide 8% ~ 12%, yog boron lossis boron dawb soda-lime silicate iav) thiabfiberglass siab alkali(sodium oxide 13% lossis ntau dua, yog iav soda-lime silicate).
Cov yam ntxwv: fiberglass dua li cov organic fibers, kub siab, tsis kub hnyiab, tiv taus corrosion, rwb thaiv tsev kub, rwb thaiv tsev suab, muaj zog tensile siab, rwb thaiv tsev hluav taws xob zoo. Tab sis brittle, tsis kam hnav. Siv rau hauv kev tsim cov yas reinforced lossis roj hmab reinforced, ua cov khoom siv reinforcing fiberglass muaj cov yam ntxwv hauv qab no:
①, lub zog tensile siab, me me elongation (3%).
②, Cov coefficient siab ntawm elasticity, zoo rigidity.
③, Siab elongation nyob rau hauv lub elastic txwv thiab siab tensile zog, yog li nws nqus tau cov nyhuv loj zog.
④, Inorganic fiber, tsis kub hnyiab, tshuaj lom neeg zoo.
⑤, Kev nqus dej me me.
⑥, Kev ruaj khov ntawm nplai thiab kev tiv taus cua sov zoo.
⑦, Kev ua tau zoo, tuaj yeem ua rau hauv cov xov, cov pob khoom, cov ntaub, cov ntaub thiab lwm yam khoom sib txawv.
⑧, Pob tshab thiab lub teeb kis tau.
⑨, Zoo adhesion rau resin.
⑩, Pheej yig.
⑪, tsis yooj yim hlawv, tuaj yeem yaj ua cov hlaws iav ntawm qhov kub siab.

Cov txheej txheem ntau lawm ntawmfiberglass
Muaj ob hom txheej txheem tsim cov fiberglass:
Ob lub molding: txoj kev kos duab crucible
Ib zaug molding: Pas dej ua ke kiln kos duab txoj kev
Cov txheej txheem kos duab hlau Crucible, thawj cov khoom siv iav raw yaj ntawm qhov kub siab rau hauv lub pob iav, thiab tom qab ntawd yaj lub pob iav thib ob, kos duab ceev ceev ua los ntawm cov iav fiber nyoos. Cov txheej txheem no muaj kev siv hluav taws xob ntau, cov txheej txheem molding tsis ruaj khov, kev tsim khoom tsawg thiab lwm yam tsis zoo, feem ntau tshem tawm los ntawm cov chaw tsim khoom loj iav fiber.
Txoj kev kos duab hlau ntawm lub pas dej ua ke hauv lub qhov cub siv cov chlorite thiab lwm yam khoom siv raw hauv lub qhov cub yaj rau hauv cov kua iav, tsis suav nrog cov pa npuas los ntawm txoj kev thauj mus rau lub phaj xau, kev kos duab ceev ceev ua los ntawm cov fiberglass filaments. Lub qhov cub tuaj yeem txuas nrog ntau txoj kev mus rau ntau pua lub phaj xau rau kev tsim khoom tib lub sijhawm. Cov txheej txheem no yooj yim, txuag hluav taws xob, pwm ruaj khov, ua haujlwm tau zoo thiab muaj txiaj ntsig zoo, los pab txhawb kev tsim khoom loj, ua lub hauv paus tseem ceeb ntawm cov txheej txheem tsim khoom thoob ntiaj teb, nrog rau cov txheej txheem tsim khoom ntawm fiberglass suav rau ntau dua 90% ntawm kev tsim khoom thoob ntiaj teb.

Kev Lag Luam Fiberglass
Raws li cov ntaub ntawv raw sib txawv xaiv rau kev tsim khoom, fiberglass tuaj yeem muab faib ua cov tsis-alkali, nruab nrab alkali,alkali siab thiab fiberglass tshwj xeeb; raws li qhov sib txawv ntawm cov fiber, fiberglass tuaj yeem muab faib ua fiberglass txuas ntxiv mus, fiberglass ntev ruaj khov, iav ntaub plaub; raws li qhov sib txawv ntawm txoj kab uas hla ntawm monofilaments, fiberglass tuaj yeem muab faib ua ultra-fine fibers (txoj kab uas hla tsawg dua 4 μm), cov fibers laus (txoj kab uas hla ntawm 3 ~ 10 μm), cov fibers nruab nrab (txoj kab uas hla ntawm) ntau dua 20μm), cov fibers ntxhib (txoj kab uas hla ntawm txog 30μm). Raws li qhov sib txawv ntawm cov fiber, fiberglass tuaj yeem muab faib ua fiberglass ib txwm muaj, fiberglass muaj zog acid thiab alkali resistant, fiberglass muaj zog acid resistant,fiberglass uas tiv taus kub siab, lub zog fiberglass siab thiab lwm yam.
