Kedu ihe kpatara Sintering ji bụrụ nzọụkwụ dị oke egwu na-ekpebi arụmọrụ ikpeazụ nke akwa fiberglass mkpuchi PTFE?

Na Jiangsu Aokai Advanced Materials Technology Co., Ltd., usoro sintering maka PTFE mkpuchi fiberglass ákwà a na-ahụta dị ka 'obi na mkpụrụ obi' nke mmepụta. Ọ fundamentally transforms anụ ahụ rapaara PTFE ahụ n'ime a na-aga n'ihu film oyi akwa na ahụkebe arụmọrụ, na-ekpebi ma PTFE ákwà pụrụ n'ezie ibu a elu-arụmọrụ mejupụtara ihe. A na-enyocha nke a na omimi site na akụkụ anọ dị n'okpuru.

1. Microstructural mgbanwe: Site na 'Particle Stacking' na 'Na-aga n'ihu Film Formation'

Mgbe impregnation na ihicha, PTFE dị naanị dị ka rụrụ, ezi ahụ edebe n'elu na n'ime interstices nke fiberglass mkpụrụ. N'oge a, akwa akwa nke agwụchachara enweghị ike bara uru, mkpuchi ahụ na-apụkwa ngwa ngwa na obere esemokwu.

Ọrụ nke Sintering : N'ebe okpomọkụ dị elu nke 360-380 ° C, ihe ndị PTFE na-agbaze, mgbasa, na coalescence iji mepụta ihe nkiri dị egwu, na-aga n'ihu, na-enweghị porous nke na-ekpuchi fiberglass nke ọma. Na-enweghị mgbanwe a, akwa enweghị ike nweta mbinye aka ya na-abụghị osisi, kemịkalụ na-eguzogide ọgwụ, na ihe mkpuchi ọkụ eletrik.

2. Ịchọpụta ike nkekọ na akụrụngwa akụrụngwa

Fiberglass na PTFE bụ ihe ndị na-enweghị atụ. Njikọ ihu na-adịghị mma na-eduga na delamination mkpuchi, ọnya, ma ọ bụ bee n'oge ọrụ.

Interfacial Fusion na Crystallinity Control : N'oge sintering, a wụrụ awụ PTFE banye na arịlịka n'ime micropores na ike ike elu nke fiberglass, na-eke n'ibu interlocking. Ka ọ dị ugbu a, ikpo ọkụ ziri ezi na ọnụego jụrụ oyi na-achịkwa kristal nke PTFE. Nnyocha na-egosi na akwa PTFE dị n'okpuru-sintered nwere obere kristal na nrapado na-adịghị mma, na mkpuchi nke na-eyi ngwa ngwa n'okpuru mgbagha ma ọ bụ abrasion ugboro ugboro. Naanị usoro sintering a na-achịkwa nke ọma na-eme ka ike bee dị mma, ike ntakiri na ndụ mgbanwe.

3. Ịmepụta njupụta ikpeazụ na mgbochi mgbochi

Fiberglass n'onwe ya na-agbaji agbaji, na-anaghị eyi ya nke ọma, ọ dịkwa mfe ịnweta hydrolysis. Ọrụ pụtara ìhè nke akwa mkpuchi PTFE na-adabere kpamkpam na oyi akwa mkpuchi PTFE siri ike.

Ikpochapụ ntụpọ na ịmepụta ihe mgbochi :Sintering fuses na-ewepụ micro pinholes, ikuku ikuku, na ntụpọ ndị ọzọ site na usoro ndị gara aga, na-emepụta ihe mgbochi 'ihe mgbochi nchebe.' Nke a na-egbochi ihe mgbochi na-enyere aka ogologo oge iguzogide acid siri ike, alkalis, na organic solvents, mgbe ọ na-ebuga arụmọrụ na-adịghị mma na ọkụ eletrik. Na nkenke, ịdịmma sntering na-akọwa kpọmkwem njedebe ngwa nke akwa - ma maka ebumnuche izugbe na-abụghị nke ebufe eriri ma ọ bụ ihe mkpuchi ikuku-ọkwa.

4. Mmetụta dị oke egwu nke Parameters Sintering na Ogo ngwaahịa

Sintering nwere windo usoro kachasị dị warara na nke siri ike na mmepụta ákwà PTFE; obere ndahie na paramita na-eduga n'iche dị egwu na arụmọrụ.

Kpọmkwem nguzozi nke okpomọkụ na oge :Okpomọkụ na-ezughị ezu ma ọ bụ ogologo oge na-arụpụta 'under-sintering': PTFE anaghị emepụta ihe nkiri n'ụzọ zuru ezu, na-ahapụ mkpuchi rụrụ arụ, na-acha ọcha, na-adịghị mma na nguzogide kemịkalụ na-adịghị mma. Oke okpomoku ma ọ bụ oge ibi na-akpata ire ere nke PTFE, na-ahapụ uzuzu na-egbu egbu, na-ebelata ike mkpụrụ, na-eme ka ákwà ahụ na-agbaji ma na-acha odo odo, na-eme ka ọ ghara ịdị irè.

Mmetụta dị oke egwu nke ọnụego jụrụ oyi : Ọnụego jụrụ oyi mgbe sentering na-ekpebi morphology kristal na crystallinity nke PTFE. Ngwa ngwa jụrụ oyi na-emepụta kristal dị ala, akwa na-agbanwe agbanwe nke ọma maka ngwa na-ehulata ike. Nji nwayọ nwayọ na-etolite kristal dị elu, ike siri ike, akwa na-adịghị akwa uwe dabara adaba maka akara static.
