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 na-emepụta fibers 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.Igwe na-enweghị Alkali nwere ihe mkpuchi dị mma na akụrụngwa akụrụngwa, 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 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.Ọ nwekwara àgwà 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 iko, filaments iko ndị a na-ejikọta tupu ikuku ikuku kwesịrị ịdị nha, na obere eriri ga-eji mmanụ mma fesa tupu a chịkọta ya na oghere.
(2) Nhazi ọzọ, dị ka ọnọdụ nke obere iko fiber na mkpụmkpụiko eriri roving e nwere usoro ndị a:
① Usoro nhazi eriri obere iko:
