Ingaruka zubushuhe bwibidukikije kuri PTFE Emulsion Impregnation

Mubikorwa nyabyo byo gutunganya imyenda ya PTFE yubushyuhe bwo hejuru na Jiangsu Aokai Ibikoresho bishya, ubushuhe bwibidukikije busanzwe bugenzurwa murwego rwihariye rwa 40% - 60% RH , hamwe no kugenzura ubushyuhe. Igipimo cyo guhumeka cyahinduwe kugirango kigabanuke gato ugereranije n’igipimo cy’ubwikorezi bwa capillary y’amazi muri emulsiyo mu muyoboro wa capillary, bituma yinjira neza kandi uringaniza emuliyoni mugihe ugera kuri firime zidafite inenge, zuzuye cyane PTFE.

Ingaruka nyamukuru yubushuhe bwibidukikije kuri PTFE emulsiyasi yatewe no kuringaniza imbaraga hagati yumuvuduko wamazi no guhagarara kwa emulisiyo. Emulioni ya PTFE mubisanzwe ni amazi atari Newtonian agizwe nuduce duto twa PTFE (icyiciro gitatanye), surfactants, stabilisateur, namazi (icyiciro gikomeza). Nkibidukikije, ubushuhe bugenga ihindagurika ryimikorere ya solvent (amazi), bigira ingaruka zifatika kuburyo bukurikira:

1. Ingaruka zifatizo kuri gahunda yo Kwinjira

Icyiciro cyo gutera akabariro gisaba emulsiyo kwinjira neza mu byobo cyangwa mu cyuho cya fibre ya substrate (urugero, umwenda w'ikirahure, ibirahuri by'icyuma).

Ubushuhe buke : Amazi ashira vuba vuba, bigatuma emulioni 'hejuru-yumye ' byihuse kuri substrate. Ibi byongera cyane ubwiza bugaragara bwa emulsiyo kuri interineti, bikabuza capillary kwinjira kwingirangingo zinjira mubutaka bwimbitse hanyuma bikavamo 'kwinjirira bidahagije ' - ni ukuvuga umufuka wumwuka usigaye imbere muri substrate. Hagati aho, guhumeka vuba bikuraho ubushyuhe bwinshi, bushobora gutera ubushyuhe butunguranye bwaho, bigahungabanya emulsiyo ya termodinamike kandi bigatera imvura igwa, biganisha kuri 'igishishwa cya orange ' cyangwa umubyimba utaringaniye murwego rwatewe.

Ibidukikije bifite ubuhehere bwinshi : Guhumeka kwamazi birabujijwe, kandi emulioni iguma mumiterere yubushyuhe buke buke kuri substrate kumwanya muremure cyane. Kuburyo buhagaritse cyangwa bugororotse, kugabanuka kugaragara byoroshye munsi ya rukuruzi; kubutaka bwa hygroscopique cyane, ubuhehere bwinshi burashobora kubuza gusohora gaze imbere muri substrate, bigakora mikorobe ikura ikagira inenge ya pinhole mugihe cyo gucumura nyuma.

2. Ingaruka zifatizo kumiterere yanyuma ya firime

Imiterere ya firime ya PTFE ikubiyemo ibyiciro bibiri: gukama (kuvanaho amazi) no gucana ubushyuhe bwo hejuru (gushonga ibice). Ubushuhe bugira ingaruka cyane cyane kumiterere yicyatsi kibisi mugihe cyumye, kikaba 'cyarazwe ' muri firime yanyuma.

Kumeneka no guhangayika imbere : Gukora firime ya PTFE resin ibice bishingiye kumuvuduko wa capillary mugihe cyo guhumeka kwamazi kugirango ugabanye ibice mubice byuzuye. Ubushuhe bukabije butera kwiyongera gukabije kwingutu ya capillary gahoro gahoro no kugabanuka byumye cyane, bikabyara impagarara nini imbere mumubiri wicyatsi. Kubera ko PTFE idafite ubushobozi bwo kwikiza mbere yo gucumura, imihangayiko nkiyi iganisha kuri microcrack cyangwa macroscopique gucika mumubiri wicyatsi. Ibi bice ntibishobora kuvaho nyuma yo gucumura, bikaviramo firime kumeneka cyangwa kugabanya imbaraga za mashini.

Kwimuka kwa surfactant hamwe nibisigara : Surfactants (nkibisimburwa na acide ya perfluorooctanoic) ikubiye muri emulisiyo yubucuruzi ya PTFE yimuka hamwe no guhumeka amazi mugihe cyumye. Ubushuhe buhebuje bwagura idirishya ryumye, bigatuma umwanya uhagije kugirango surfactants zegerane hejuru, bigakora 'amavuta yo hejuru ' cyangwa uruhu rukomeye. Niba iki gipimo kitarangiritse rwose cyangwa ngo gihindurwe mugihe cyambere cyo gucumura, bizashyirwa karuboni kandi bigashyirwa imbere muri firime, bigatera umuhondo, kugabanya ubucucike, no kugabanuka gukomeye hagati ya PTFE na substrate (guhuza imiyoboro idahwitse bitewe no kwigunga kwanduye).

Ubucucike bwa firime nubwitonzi : Filime nziza ya PTFE igomba kuba idafite pinhole kandi yuzuye. Kugenzura ubuhehere budakwiye buganisha ku bushyuhe busigaye ni akaga gakomeye. Mugihe cy'ubushyuhe bwinshi, niba amazi adakuweho burundu mugihe cyo gushyushya no gukama, ubuhehere busigaye bugenda buhinduka ako kanya mugihe cyo gucumura gukurikiraho (hafi 327-400 ° C) hamwe no kwaguka kwinshi, bigatuma habaho ibibyimba cyangwa ibisebe hagati ya firime yashonze igice. Ku rundi ruhande, mu gihe cy'ubushyuhe buke cyane, kwumisha hejuru byihuse bigira uruhu rufunze rubuza amazi yo mu nda imbere, bikanatera ibisebe cyangwa gusibanganya mugihe cyo gucumura kubera umuvuduko mwinshi wumuyaga.

Ihame, ingaruka z’ubushuhe bw’ibidukikije ku gutunganya emulsiyo ya PTFE ni uruhare runini mu bikorwa byo guhumeka amazi:

·  Ubushuhe buke (gukama cyane)  bikunda gutera: kwinjira nabi, kuringaniza kuringaniza (kugabanya imyanda), kumisha, no gukwirakwiza ibisigazwa bya surfactant.

·  Ubushuhe bwinshi (ubushuhe bukabije)  bukunda gutera: kugabanuka, kwiyongera kwa pinholes, kureremba hejuru kureremba hejuru, kubyimba nyuma yo gucumura, no kugabanya gufatira hamwe.
