Spunlace nke na-adịghị kpara eriri nke tupu oxygen
Ahịa ngalaba:
Njirimara nke Fiber ebuburu oxygen:
· Ultimate Flame Retardanancy: Oke oxygen index (LOI) na-abụkarị> 40 (oke oxygen na ikuku bụ ihe dịka 21%), karịa karịa nke eriri ọkụ na-ere ọkụ (dị ka polyester na-ere ọkụ na LOI nke ihe dịka 28-32). Ọ naghị agbaze ma ọ bụ na-agbaze mgbe ọkụ na-ekpo ọkụ, na-emenyụ onwe ya mgbe ọ wepụsịrị isi ọkụ ahụ, na-ahapụkwa obere anwụrụ ọkụ na ọ dịghị gas na-egbu egbu n'oge combustion.
· High-okpomọkụ kwụsie ike: The ogologo oge ojiji okpomọkụ nwere ike iru 200-250 ℃, na obere oge nwere ike idi 300-400 ℃ elu okpomọkụ (kpọmkwem dabere na akụrụngwa na pre-oxidation ogo). Ọ ka na-edobe iguzosi ike n'ezi ihe nhazi yana ihe eji arụ ọrụ na gburugburu oke okpomọkụ.
· Nguzogide kemịkalụ: Ọ nwere ụfọdụ nguzogide acid, alkalis, na ihe mgbaze organic, ọ naghịkwa emebi ngwa ngwa site na ihe kemịkalụ, dabara adaba maka iji na gburugburu ebe siri ike.
Ụfọdụ ihe arụrụ arụ: O nwere ụfọdụ ike ike na ike siri ike, enwere ike mee ya ka ọ bụrụ ihe nwere usoro kwụsiri ike site na usoro nhazi akwa na-abụghị nke kpara akpa (dị ka ịkụ ọkpọ, spunlace).
II. Nkà na ụzụ nhazi nke ákwà anaghị kpara akpa oxygen
Ekwesịrị ịhazi eriri nke etinyere oxygen ka ọ bụrụ ihe na-aga n'ihu dị ka akwụkwọ site na usoro nhazi akwa na-abụghị nke kpara akpa. Usoro ndị a na-ahụkarị gụnyere:
· Ụzọ ịkụ ọkpọ: Site n'iji agịga igwe agịga atụtu eriri eriri ugboro ugboro, eriri ndị ahụ na-ejikọta ma na-ewusi ibe ha ike, na-akpụ ákwà na-abụghị nke nwere ụfọdụ ọkpụrụkpụ na ike. Usoro a dabara adaba maka imepụta akwa akwa ikuku oxygen, nke nwere ike iji mee ihe n'ọnọdụ ndị chọrọ nkwado nhazi (dị ka ogwe ọkụ ọkụ, ihe nzacha ọkụ ọkụ).
Usoro spunlaced: N'iji ụgbọ elu mmiri dị elu na-emetụta eriri eriri, eriri na-ejikọta ọnụ ma jikọta ọnụ. Uwe a na-ekpo ọkụ na-ekpo ọkụ nke spunlaced nwere mmetụta dị nro na ume ume ka mma, ọ dịkwa mma maka iji n'ime akwa mkpuchi nke uwe nchebe, ihe mkpuchi ọkụ na-agbanwe agbanwe, wdg.
· Thermal bonding / Chemical bonding: Site na iji obere-agbaze eriri eriri (dị ka ire-retardant polyester) ma ọ bụ adhesives na-enyere aka na mkwado, stiffness nke dị ọcha pre-oxygenated fiberless ákwà nwere ike belata, na nhazi arụmọrụ nwere ike mma (ma mara na okpomọkụ iguzogide nke nrapado kwesịrị dakọtara na ojiji gburugburu ebe obibi nke pre-oxygen).
Na mmepụta n'ezie, a na-ejikọta eriri ndị na-ebu ụzọ oxidized na eriri ndị ọzọ (dị ka aramid, viscose flame-retardant, glass fiber) iji mee ka ọnụ ahịa, mmetụta na ịrụ ọrụ (dịka ọmụmaatụ, akwa ákwà na-adịghị edozi tupu oxidized siri ike, ma na-agbakwụnye 10-30% ọkụ-retardant viscose nwere ike imeziwanye nro).
III. Ihe ngosi ngwa akọwapụtara nke eriri eriri anaghị kpara akpa
N'ihi ihe na-egbochi ọkụ ya na ihe na-eguzogide okpomọkụ, eriri na-abụghị nke a kpara akpa oxidized na-arụ ọrụ dị mkpa n'ọtụtụ ubi:
1. Mgbochi ọkụ na nchedo onwe onye
· Igwe ọkụ dị n'ime ime / oyi akwa: Pre-oxidized na-abụghị nke a kpara akpa bụ ọkụ na-egbochi ọkụ, okpomọkụ na-eguzogide ma na-eku ume, a pụkwara iji ya mee ihe dị ka isi oyi akwa nke ọkụ na-adaba adaba iji gbochie nnyefe ọkụ na okpomọkụ dị elu, na-echebe akpụkpọ anụ nke ndị na-ere ọkụ; mgbe ejikọtara ya na aramid, ọ nwekwara ike imeziwanye nkwụsi ike na-eyi na nkwụsi ike.
Ngwá ọrụ nchebe nke ịgbado ọkụ / ọla: Ejiri ya maka mkpuchi mkpuchi ịgbado ọkụ, mkpuchi na-ekpo ọkụ na-ekpo ọkụ, apịtị ndị ọrụ igwe, wdg, iji guzogide ọkụ ọkụ na-efe efe na radieshon dị elu (na obere oge okpomọkụ na-eguzogide ihe karịrị 300 ° C).
Ihe mgbapụ ihe mberede: dị ka mkpuchi mkpuchi ọkụ, ihe nzacha ihe nkpuchi nkpuchi, nke nwere ike kechie ahụ ma ọ bụ yochaa anwụrụ ọkụ n'oge ọkụ (ọkụ dị ala na adịghị egbu egbu dị mkpa).
2. Industrial elu-okpomọkụ nchebe na mkpuchi
· Ihe mkpuchi ụlọ ọrụ: A na-eji ya dị ka mkpuchi dị n'ime nke ọkpọkọ okpomọkụ dị elu, ihe mkpuchi ọkụ ọkụ, wdg, iji belata okpomọkụ ma ọ bụ nnyefe (nkwụsị ogologo oge na 200 ° C na gburugburu gburugburu).
· Ihe eji ewu ụlọ ọkụ: Dị ka mkpuchi mkpuchi nke mkpuchi mkpuchi ọkụ na ọkụ ọkụ na ụlọ elu dị elu, ma ọ bụ ihe mkpuchi eriri USB, na-egbu oge mgbasa ọkụ (na-ezute GB 8624 ọkụ na-eguzogide ọkwa B1 na n'elu chọrọ).
· Nchebe akụrụngwa dị elu: Dị ka ákwà mgbochi oven, mkpuchi mkpuchi ọkụ maka ọkụ ọkụ na oven, iji gbochie ndị ọrụ ọkụ site na elu okpomọkụ nke ngwá ọrụ ahụ.
3. Ebe nzacha ọkụ dị elu
· Ntucha anwụrụ ọkụ nke ụlọ ọrụ: Okpomọkụ gas anwụrụ ọkụ sitere na ihe mkpofu mkpofu, igwe igwe igwe, ọkụ mmeghachi omume kemịkalụ na-erukarị 200-300 Celsius, ma nwee gas acid. Pre-oxidized na-abụghị kpara akwa na-eguzogide ọgwụ dị elu okpomọkụ na corrosion, na ike ga-eji dị ka isi ihe maka nzacha akpa ma ọ bụ nyo cylinders, rụọ ọrụ nke ọma iyo.
4. Ndị ọzọ pụrụ iche ndapụta
Ihe enyemaka Aerospace: ejiri ya dị ka mkpuchi mkpuchi ọkụ n'ime ụlọ ụgbọ elu yana mkpuchi mkpuchi ọkụ gburugburu igwe rọketi (nke kwesịrị iji resins na-eguzogide okpomọkụ mee ka ọ dịkwuo elu).
Ihe mkpuchi eletriki: Ejiri ya dị ka gaskets mkpuchi na moto okpomọkụ dị elu na ihe ntụgharị, ha nwere ike dochie ihe asbestos omenala (na-abụghị carcinogenic na ndị ọzọ na gburugburu ebe obibi).
Iv. Uru na Uru mmepe nke Fiber Nonwoven Fiber Oxidized
Uru: E jiri ya tụnyere ihe ọdịnala ọdịnala na-egbochi ire ọkụ (dị ka asbestos na fiber glass), eriri na-abụghị nke a kpara akpa oxygenated bụ nke na-abụghị carcinogenic ma nwee mgbanwe ka mma. E jiri ya tụnyere eriri dị ọnụ ahịa dị elu dị ka aramid, ọ nwere ọnụ ala dị ala (ihe dị ka 1/3 ruo 1/2 nke aramid) ma dị mma maka ngwa batch na ihe ngosi ọkụ na-ere ọkụ dị elu.
Trend: welie compactness na filtration arụmọrụ nke na-abụghị kpara akwa site eriri ukpụhọde (dị ka ezi denier pre-oxygenated filaments, dayameta <10μm); Zụlite usoro nhazi gburugburu ebe obibi na formaldehyde dị ala na enweghị nrapado; Ejikọtara ya na nanomaterials (dị ka graphene), ọ na-eme ka nguzogide okpomọkụ dị elu na ihe ndị na-egbu egbu.
N'ikpeazụ, ngwa nke tupu oxidized emep uta eri na-abụghị kpara akwa hinges na ha mejupụtara Njirimara nke "ire ọkụ retardancy na elu okpomọkụ iguzogide" ilebara arụmọrụ adịghị ike nke omenala ihe na elu okpomọkụ na-emeghe ire ọkụ gburugburu. N'ọdịnihu, na nkwalite nke nchekwa ụlọ ọrụ na ụkpụrụ nchebe ọkụ, a ga-agbasawanye ihe ngosi ngwa ha.
