Glass fiber nwere ihe magburu onwe ya ma na-eji ya n'ọtụtụ ebe. Ọ bụ ihe inorganic na-abụghị ọla nke nwere ike dochie ígwè. N'ihi atụmanya mmepe ya dị mma, nnukwu ụlọ ọrụ fiber iko na-elekwasị anya na nyocha nke arụmọrụ dị elu na nhazi nhazi nke eriri iko.
1 Nkọwa nke eriri iko
Glass fiber bụ ụdị inorganic na-abụghị ọla ihe nwere ike dochie metal ma nwee ọmarịcha arụmọrụ. A na-akwado ya site n'itinye iko a wụrụ awụ n'ime eriri site na ike mpụga. Ọ nwere njirimara nke ike dị elu, modul dị elu na elongation dị ala. Okpomọkụ na-eguzogide na mkpakọ, nnukwu thermal mgbasa ọnụọgụ, elu agbaze ebe, ya softening okpomọkụ nwere ike iru 550 ~ 750 ℃, ezigbo chemical kwụsie ike, adịghị mfe ọkụ, nwere ụfọdụ magburu onwe e ji mara dị ka corrosion eguzogide, na e ọtụtụ-eji na ọtụtụ ubi. .
2 Njirimara nke eriri iko
Ebe agbaze nke eriri iko bụ 680 ℃, ebe esi esi bụ 1000 ℃, na njupụta bụ 2.4 ~ 2.7g / cm3. Ike nkwụsịtụ bụ 6.3 ruo 6.9 g / d na steeti ọkọlọtọ yana 5.4 ruo 5.8 g / d na steeti mmiri.Igwe eriri nwere ezigbo okpomọkụ na-eguzogide ma bụrụ ihe mkpuchi dị elu nke nwere ihe mkpuchi dị mma, nke kwesịrị ekwesị maka mmepụta ihe mkpuchi ọkụ na ihe ọkụ ọkụ.
3 Ihe mejupụtara nke eriri iko
Igwe a na-eji emepụta eriri iko dị iche na iko a na-eji na ngwaahịa iko ndị ọzọ. Igwe a na-eji na-emepụta eriri iko nwere ihe ndị a:
(1)E-glass,nke a makwaara dị ka iko na-enweghị alkali, bụ nke iko borosilicate. N'ime ihe ndị a na-eji ugbu a na-emepụta fibers iko, iko na-enweghị alkali bụ ihe a na-ejikarị eme ihe. Iko na-enweghị Alkali nwere ezigbo mkpuchi na ihe eji arụ ọrụ, a na-ejikarị emepụta fibers iko na-ekpo ọkụ na iko iko dị elu, mana iko na-enweghị alkali anaghị eguzogide corrosion inorganic acid, yabụ na ọ naghị adabara iji na gburugburu acidic. . Anyị nwere e-glassfiberglass na-agba ọsọ, e-glassfiberglass kpara akpa,na e-glassfiberglass ute.
(2)C-iko, makwaara dị ka ọkara alkali iko. E jiri ya tụnyere iko na-enweghị alkali, ọ nwere nguzogide kemịkalụ ka mma yana akụrụngwa eletrik na igwe adịghị mma. Ịgbakwunye diboron trichloride na ọkara alkali iko nwere ike imepụtaiko eriri elu ute,nke nwere njirimara nke nguzogide corrosion. A na-ejikarị eriri enyo enyo na-enweghị alkali na-enweghị boron na mmepụta nke akwa nzacha na akwa mkpuchi.
(3)eriri iko dị elu,dị ka aha ahụ na-egosi, eriri iko iko dị elu nwere njirimara nke ike dị elu na modul dị elu. Ike ike eriri ya bụ 2800MPa, nke dị ihe dị ka 25% dị elu karịa nke eriri iko na-enweghị alkali, modulus ya bụ 86000MPa, nke dị elu karịa nke eriri E-glass. Ihe mmepụta nke eriri iko iko dị elu adịghị elu, yana ike ya dị elu na modul dị elu, ya mere a na-ejikarị ya eme ihe na agha, ikuku ikuku na egwuregwu na mpaghara ndị ọzọ, ọ dịghịkwa eji ya na mpaghara ndị ọzọ.
(4)AR iko eriri, nke a makwaara dị ka eriri iko na-eguzogide alkali, bụ eriri inorganic. The alkali-eguzogide iko eriri nwere ezi alkali iguzogide na ike iguzogide corrosion nke elu alkali bekee. Ọ nwere modul ngbanwe dị oke elu na nguzogide mmetụta, ike nkwụ na mgbada. O nwekwara njirimara nke enweghị combustibility, ntu oyi na-eguzogide, okpomọkụ na iru mmiri na-eguzogide, mgbape na-eguzogide, impermeability, ike plasticity na mfe ịkpụzi. Ọgịrịga ihe maka iko eriri mesikwuru ihe.
4 Nkwadebe nke eriri iko
Usoro mmepụta nkeeriri ikobụ n'ozuzu ibu ụzọ gbazee ihe ndị dị n'ime ya, wee mee ọgwụgwọ fiberizing. Ọ bụrụ na a ga-eme ya ka ọ bụrụ bọọlụ eriri iko ma ọ bụ mkpanaka fiberglass, a pụghị ime ọgwụgwọ fiberizing ozugbo. Enwere usoro fibrillation atọ maka eriri iko:
Usoro ịse: usoro bụ isi bụ usoro ihe osise filament nozzle, na-esote usoro ihe osise iko na usoro ịgbaze dobe;
Usoro Centrifugal: centrifugation drum, nzọụkwụ centrifugation na kehoraizin poselin disc centrifugation;
Usoro ịfụ: usoro ịfụ na usoro ịfụ ọkụ.
Ọtụtụ usoro ndị a dị n'elu nwekwara ike ijikọ ọnụ, dị ka ịse-ịfụ na ihe ndị ọzọ. Post-processing na-ewere ọnọdụ mgbe fiberizing. E kewara nhazi nke eriri iko textile n'ime usoro abụọ bụ isi:
(1) N'oge a na-emepụta fibers ugegbe, filaments iko ndị a na-ejikọta tupu ikuku ikuku kwesịrị ịdị nha, na obere eriri ga-eji mmanụ mma fesa tupu a nakọta ya na oghere.
(2) Nhazi ọzọ, dị ka ọnọdụ nke obere iko fiber na mkpụmkpụiko eriri roving e nwere usoro ndị a:
