Muaj pes tsawg leeg 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 cov ntsiab lus alkali hauv iav, nws tuaj yeem muab faib ua:
①,non-alkali fiberglass(sodium oxide 0% ~ 2%, yog aluminium borosilicate iav)
②, nruab nrab alkali fiberglass (sodium oxide 8% ~ 12%, yog boron lossis boron dawb soda-lime silicate iav) thiabsiab alkali fiberglass(sodium oxide 13% lossis ntau dua, yog dej qab zib-lime silicate iav).
Nta: fiberglass tshaj cov organic fibers, kub kub, tsis-combustible, corrosion kuj, tshav kub rwb thaiv tsev, suab rwb thaiv tsev, siab tensile zog, zoo hluav taws xob rwb thaiv tsev. Tab sis nkig, tsis zoo abrasion kuj. Siv nyob rau hauv kev tsim cov yas reinforced los yog cov roj hmab ntxiv, raws li cov khoom siv fiberglass muaj cov yam ntxwv hauv qab no:
①, siab tensile zog, me elongation (3%).
②, Siab coefficient ntawm elasticity, zoo rigidity.
③, Siab elongation nyob rau hauv lub elastic txwv thiab siab tensile lub zog, yog li nws absorbs loj cuam tshuam lub zog.
④, Inorganic fiber, tsis-combustible, zoo tshuaj tsis kam.
⑤, Kev nqus dej me me.
⑥, Scale stability thiab kub tsis kam yog qhov zoo.
⑦, Kev ua tau zoo, tuaj yeem ua rau hauv cov hlua, pob khoom, cov ntaub, ntaub thiab lwm yam khoom sib txawv.
⑧, Pob tshab thiab lub teeb transmittable.
⑨, Zoo adhesion rau resin.
⑩, pheej yig.
⑪, tsis yooj yim rau hlawv, tuaj yeem yaj rau hauv cov hlaws dai ntawm qhov kub thiab txias.
Ntau lawm txheej txheem ntawmfiberglass
Muaj ob hom fiberglass ntau lawm txheej txheem:
Ob txoj kev molding: crucible drawing method
Ib zaug molding: Pas dej kiln drawing method
Crucible hlau daim duab txheej txheem, thawj iav raw khoom melted ntawm kub kub mus rau hauv lub khob pob, thiab ces lub thib ob melting ntawm lub khob pob, high-ceev daim duab ua los ntawm iav fiber raw lo lo ntxhuav. Cov txheej txheem no muaj kev siv hluav taws xob ntau, cov txheej txheem molding tsis ruaj khov, kev ua haujlwm tsawg thiab lwm yam tsis zoo, feem ntau tshem tawm los ntawm cov tuam txhab loj iav fiber ntau.
Pas dej kiln hlau kos duab txoj kev ntawm chlorite thiab lwm yam raw khoom nyob rau hauv lub kiln melted rau hauv ib tug iav tov, tsis suav nrog huab cua npuas los ntawm txoj kev thauj mus rau lub porous to phaj, high-speed daim duab ua los ntawm fiberglass filaments. Lub kiln tuaj yeem txuas tau los ntawm ntau txoj hauv kev mus rau pua pua ntawm cov paib xau rau kev tsim khoom ib txhij. Cov txheej txheem no yog yooj yim, txuag hluav taws xob, ruaj khov molding, high efficiency thiab siab tawm los, los pab txhawb loj-scale tag nrho automated ntau lawm, ua lub ntsiab ntawm lub thoob ntiaj teb ntau lawm txheej txheem, nrog rau cov txheej txheem ntawm zus tau tej cov fiberglass accounted rau ntau tshaj 90% ntawm lub ntiaj teb no ntau lawm.
Fiberglass Market
Raws li cov khoom sib txawv uas tau xaiv rau kev tsim khoom, fiberglass tuaj yeem muab faib ua non-alkali, nruab nrab alkali,siab alkali thiab tshwj xeeb fiberglass; Raws li qhov sib txawv ntawm cov fiberglass, fiberglass tuaj yeem muab faib ua fiberglass txuas ntxiv, ruaj-ntev fiberglass, iav ntaub plaub; Raws li qhov sib txawv ntawm txoj kab uas hla ntawm monofilaments, fiberglass tuaj yeem muab faib ua ultra-fine fibers (inch tsawg dua 4 μm), cov fibers laus (inch ntawm 3 ~ 10 μm), intermediate fibers (inch ntawm) ntau dua 20μm), coarse fibers (inch txog 30μm). Raws li qhov sib txawv ntawm cov fiberglass, fiberglass tuaj yeem muab faib ua cov fiberglass zoo tib yam, muaj zog acid thiab alkali resistant fiberglass, muaj zog acid resistant fiberglass,kub resistant fiberglass, siab zog fiberglass thiab lwm yam.
