Fiberglass yog dab tsi?

Muaj ntau homfiberglass. Lawv feem ntau tuaj yeem raug cais raws li qhov muaj pes tsawg leeg ntawm iav raw cov ntaub ntawv, monofilament txoj kab uas hla, fiber ntau pom, txoj kev tsim khoom, thiab cov yam ntxwv fiber ntau.

 

1. Kev faib tawm los ntawm iav Raw Material Composition

 

Txoj kev faib no feem ntau yog siv rau fiberglass txuas ntxiv. Nws feem ntau txawv ntawm cov ntsiab lus ntawm cov alkali hlau oxides sib txawv, uas feem ntau xa mus rau sodium oxide thiab potassium oxide. Cov no tau nkag mus rau hauv cov khoom siv iav los ntawm cov khoom xws li dej qab zib tshauv, mirabilite, thiab feldspar. Alkali hlau oxides yog ib qho ntawm cov khoom tseem ceeb ntawm cov iav zoo tib yam, thiab lawv lub luag haujlwm tseem ceeb yog txo qis qhov melting point ntawm iav. Txawm li cas los xij, qhov siab dua cov ntsiab lus ntawm alkali hlau oxides hauv iav, qhov qis dua nws cov tshuaj ruaj khov, hluav taws xob rwb thaiv tsev, thiab lub zog yuav yog. Yog li ntawd, cov ntsiab lus sib txawv alkali yog siv hauv kev tsim cov fiberglass rau kev siv sib txawv. Yog li, cov ntsiab lus alkali ntawm fiberglass feem ntau yog siv los ua tus cim kom paub qhov txawv ntawm fiberglass rau kev siv sib txawv. Raws li cov ntsiab lus alkali hauv iav muaj pes tsawg leeg, cov fibers txuas ntxiv tuaj yeem muab faib ua cov hauv qab no:

 

1.1 Alkali-dawb fiber ntau (feem ntau hu ua E- iav)
Nws muaj cov ntsiab lus R2O tsawg dua 0.8% thiab yog cov khoom siv aluminoborosilicate. Nws muaj kev ruaj ntseg zoo heev, hluav taws xob rwb thaiv tsev, thiab lub zog. Feem ntau yog siv los ua hluav taws xob rwb thaiv tsev cov ntaub ntawv, cov ntaub ntawv ntxiv rau fiberglass, thiab lub log tsheb. Nruab nrab-alkali fiber ntau: Nrog cov ntsiab lus R2O ntawm 11.9%-16.4%, nws yog sodium-calcium silicate tivthaiv. Vim nws cov ntsiab lus alkali siab, nws tsis tuaj yeem siv los ua cov khoom siv hluav taws xob, tab sis nws cov tshuaj lom neeg ruaj khov thiab lub zog yog qhov zoo. Nws feem ntau yog siv los ua cov khoom siv rau cov ntaub latex, woven fabric, acidic filter fabric, thiab window screen, thiab kuj tseem siv tau los ua cov khoom siv ntxiv rau fiberglass qhov twg cov khoom siv hluav taws xob thiab lub zog yuav tsum tsis nruj heev. Hom fiber ntau no muaj tus nqi qis dua thiab siv dav dua.

 

1.2 High-alkali fiber ntau: Cov iav iav nrog cov ntsiab lus R2O sib npaug los yog ntau dua 15%. Fiberglass kos los ntawm raw cov ntaub ntawv xws li crushed ca iav thiab crushed lub raj mis iav yog nyob rau hauv qeb no. Lawv tuaj yeem siv los ua cov dej tsis muaj dej thiab cov dej noo- cov ntaub ntawv pov thawj xws li cov roj teeb cais, cov ntaub qhwv cov yeeb nkab, thiab cov ntawv xov xwm. Tshwj xeeb fiberglass: xws li siab - lub zog iav fibers muaj li ntawm cov ntshiab magnesium- txhuas- silicon ternary ntsiab; magnesium{11}}aluminium-silicon series siab-lub zog thiab siab{14}} elasticity iav fibers; silicon{15}}aluminium-calcium{17}}magnesium series tshuaj tiv thaiv iav fibers; aluminium{18}}muaj fibers; siab-silica fibers; quartz fibers, thiab lwm yam.

 

2. Kev faib tawm los ntawm Monofilament Diameter

 

Fiberglass monofilaments yog cylindrical, yog li lawv cov thickness tuaj yeem qhia los ntawm lawv txoj kab uas hla. Feem ntau, kos fiberglass tau muab faib ua ntau hom raws li lawv txoj kab uas hla (diameter qhov tseem ceeb hauv µm):

 

2.1 Coarse Fiber: Monofilament txoj kab uas hla feem ntau yog 30 µm.

2.2 Primary Fiber: Monofilament txoj kab uas hla yog ntau dua 20 µm.

2.3 Intermediate Fiber: Monofilament txoj kab uas hla yog 10-20 µm.

2.4 High-Qib Fiber (tseem hu ua Textile Fiber): Monofilament txoj kab uas hla yog 3-10 µm.

 

Fiberglass nrog ib txoj kab uas hla monofilament tsawg dua 4 µm kuj hu ua microfibers.

 

Txawv monofilament diameters tsis tsuas yog cuam tshuam rau fiber ntau tab sis kuj cuam tshuam cov txheej txheem fiber ntau, tawm los, thiab nqi. Feem ntau, 5-10 µm fibers yog siv rau cov khoom siv textile, thaum 10-14 µm fibers yog ntau haum rau untwisted rovings, nonwoven fabrics, thiab tws strand lev.

 

3. Kev faib tawm los ntawm Fiber tsos

 

Cov tsos ntawm iav fibers, piv txwv li, lawv cov duab thiab ntev, nyob ntawm lawv txoj kev tsim khoom thiab lawv daim ntawv thov. Piv txwv li, nruam fibers (tseem hu ua textile fibers) yog theoretically infinitely nruam fibers, tsuas yog tsim los ntawm txoj kev spinneret. Tom qab ua cov ntaub ntawv, lawv tuaj yeem ua rau hauv iav xov paj, hlua, ntaub, siv, untwisted roving, thiab lwm yam khoom.

 

3.1 Tsau -Length Fibers Cov no muaj qhov txwv ntev, feem ntau 300-500mm, tab sis qee zaum tuaj yeem ntev dua, xws li cov fibers ntev uas feem ntau pom hauv cov ntaub. Piv txwv li, cov paj rwb ntev uas siv cov tshuab tshuab, thaum tawg rau hauv cov xov paj, tsuas yog ob peb puas millimeters ntev.

Lwm cov khoom lag luam suav nrog pas nrig- cov xov paj ua tiav thiab ib zaug - theem rov qab, txhua yam siv los ua cov xov paj lossis cov xov paj.

 

3.2 Iav Wool Qhov no kuj yog ib hom ruaj khov - ntev fiberglass, tab sis nws cov fibers luv dua, feem ntau tsawg dua 150mm lossis luv dua. Morphologically, nws muaj xoob, paj rwb -zoo li qauv, li no lub npe luv paj rwb. Nws yog tsuas yog siv rau rwb thaiv tsev thiab suab haum. Tsis tas li ntawd, muaj cov fibers tws, hollow fibers, iav fiber hmoov, thiab finely av fibers.

 

4. Kev faib tawm los ntawm Fiber Properties

Qhov no yog ib hom tshiab ntawm iav fiber ntau tsim los ua kom tau raws li cov kev thov tshwj xeeb thiab muaj qee yam tshwj xeeb thiab zoo dua. Nws tuaj yeem muab faib ua ntau hom: siab-lub zog iav fiber ntau, siab-modulus iav fiber ntau, siab-kub resistant fiberglass, alkali-resistant fiberglass, acid-resistant fiberglass, zoo tib yam iav fiber ntau (xa mus rau alkali-dawb thiab nruab nrab{li,{7}} iav fiber ntau low-dielectric- tsis tu ncua fiberglass, conductive fiber, thiab lwm yam.

 

Fiberglass yog siab -kev ua tau zoo inorganic tsis yog- cov khoom siv hlau. Nws thawj lub npe Askiv yog glassfiber lossis fiberglass. Nws cov khoom muaj xws li silicon dioxide, aluminium oxide, calcium oxide, boron oxide, magnesium oxide, sodium oxide, thiab lwm yam. Nws yog tsim los ntawm cov iav spheres los yog iav khib nyiab los ntawm qhov kub ntawm - kub melting, kos duab, winding, thiab weaving txheej txheem. Thaum kawg, ntau yam khoom raug tsim. Txoj kab uas hla ntawm cov iav fiber ntau monofilaments yog li ntawm ob peb micrometers mus rau ntau tshaj nees nkaum micrometers, uas yog sib npaug rau 1/20 txog 1/5 ntawm tib neeg cov plaub hau. Txhua pob ntawm fiber ntau filaments muaj ntau pua lossis ntau txhiab tus monofilaments. Lawv feem ntau yog siv los ua cov khoom siv ntxiv hauv cov khoom sib xyaw, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam, thiab tau siv dav hauv ntau yam kev lag luam hauv lub tebchaws.
