Gushushanya Imiterere ya Layeri yuburyo bugari-Ubushyuhe-Urwego PTFE Ifata Ubushyuhe Bwinshi

Ubushyuhe-bugari Kaseti ya PTFE igomba guhuza kwizerwa kuri -70 ° C (cyangwa munsi) kandi ikomeza kubaho kuri 200-260 ° C - ikirenga 300 ° C. Ibi birasaba sisitemu ifatika ikomeza guhinduka nta kunanirwa guhuriza hamwe cyangwa gutandukana hagati yabyo bikabije.

Igice gifatika ni ubusanzwe budasanzwe bwa silicone yunvikana (PSA) yometse kuri firime ya PTFE yahinduwe hejuru cyangwa igitambaro cya fiberglass ya PTFE. Urufunguzo rwo gukora neza murwego rwubushyuhe bwagutse ruri mukubaka umuyoboro uhuza imiterere - igishushanyo mbonera kiringaniza ubushyuhe buke, ubushyuhe bwo hejuru bw’ubushyuhe, hamwe no kwihanganira ubushyuhe.

Aokai PTFE yateje kaseti yubushyuhe bwa PTFE ikoresheje amahame yasobanuwe hepfo. Iyi ngingo isobanura ibintu bine byingenzi byashushanyijemo: imiterere yinzibacyuho, microstructure ya biphasic yinyanja-ikirwa, guhuza buhoro buhoro, hamwe nubushyuhe bwuzuye-bwuzuye bwuzuye.

Imiterere yinzibacyuho Hagati ya Substrate na Adhesive Layeri

1. Ikibazo gikomeye - ingufu za PTFE

PTFE igaragaramo ingufu zo hasi cyane (ingoma 18-20 / cm). Ipfundikizo itaziguye ifata neza mugihe cyo gusiganwa ku magare kubera ubushyuhe bwo kwagura ubushyuhe budahuye - PTFE yagura 30-40x kuruta fibre.

2. Gukoresha isura hamwe na primer anchoring

Kugira ngo iki kibazo gikemuke, ubuso bwa PTFE bukorerwa imiti hamwe na sodium-naphthalene cyangwa kuvura plasma kugirango hamenyekane C = C inshuro ebyiri hamwe na ogisijeni irimo amatsinda ya polar. Nyuma yibyo, ultr-thin yeguriwe silicone primer (urugero, vinyl irimo silane ihuza silane) ikoreshwa kugirango ikore 'ikiraro cya molekile ' kuri interineti hifashishijwe imiti ihuza imiti.

3. Guhangayikishwa cyane

Mubisobanuro bimwe na bimwe, modulus yo hasi, ihindagurika cyane ya elastique intera intera (gel-nka silicone ifite ibice byoroshye) yinjizwa hagati yurwego rukora nigice kinini gifatika. Ibi bikurura impagarara ziterwa no guhindagurika kwubushyuhe bukabije kandi bikarinda kuzamura inkingi.

Inyanja-Ikirwa cya Biphasic Microstructure Amabwiriza

Matrix nyamukuru ifata ni sisitemu ya kera ya PSA igizwe na resin ya MQ silicone (ikirwa cyatatanye ikirwa) hamwe na polyisiloxane ifite uburemere buke (icyiciro cyinyanja gikomeza).

1. MQ silicone resin - icyiciro cyizinga gikomeye

Itanga ubumwe, gufata imbaraga, hamwe nubushyuhe bwo hejuru bwo guhangana. Kugenzura neza igipimo cyayo cya M / Q (mubisanzwe 0,6-0.9) hamwe nubunini bwikwirakwizwa ryemeza ko byinjizwa mubice bikomeza kugirango bibe bihuza umubiri.

2. Polysiloxane icyiciro gikomeza - icyiciro cyinyanja cyoroshye

Gutanga byihuse, ubushyuhe buke bwo hasi, no guhinduka. Uburemere-buremereye bwa methyl vinyl silicone reberi cyangwa methyl phenyl vinyl silicone reberi iratoranijwe.

3. Gutezimbere bidasanzwe kubushyuhe bugari

Umubare muto wibice byinshi bya fenyl birimo siloxane ibice birimo. Amatsinda ya fenyl ahagarika ubushyuhe buke bwa kristalisiti ya polydimethylsiloxane, bikagabanya ubushyuhe bwubushyuhe buri munsi ya -100 ° C. Hagati aho, amatsinda ya fenyl yongerera imbaraga ubushyuhe bwa okiside yubushyuhe bukabije, bigatuma icyiciro cyinyanja gikomeza kugumana ubukana bwinshi hejuru yidirishya ryubushyuhe.

Igice kinini cyangwa Gradient Kwambukiranya Igishushanyo cya Thermal Shock Resistance

Uburyo bubiri bwo gutwikira bwakoreshejwe kugirango habeho kuringaniza ubushyuhe bwo hejuru hamwe nubushyuhe buke:

1. Igice cyimbere (kuruhande)

Ugereranije, ubucucike buri hejuru , butanga ubushyuhe bwo hejuru bwo gufata imbaraga nimbaraga zifatika nkurwego rudashobora gukata.

2. Igice cyo hanze (guhuza ubuso)

Ultra-low crosslink ubucucike hamwe nu munyururu wa molekile igendanwa cyane, bigatuma amazi yihuta ku bayoboke ku bushyuhe buke kandi bihagije.

Ubundi, icyiciro gikomeza cyerekana ubucucike bwimbere kuva imbere kugeza hanze bugizwe murwego rumwe binyuze muburyo bwo gukiza, guhuza ibice bikora kandi byoroshye.

Aokai PTFE ikoresha ikorana buhanga rya tekinoroji kugirango irebe ko kaseti ikomeza guhinduka kuri -70 ° C (itanga uburyo bwambere bwo guhuza no guhuza) mugihe ikomeza imbaraga zifatika kuri 260 ° C (gukumira kunyerera no kwimura).

Ubushyuhe-Bwuzuye Buzuzanya

Nano-nini ya silika ya silika ikwirakwizwa neza muri matrike ifatika kugirango ikomeze, ihujwe nibyiciro bibiri byuzuza imikorere:

1. Ibyongeweho birwanya ubushyuhe

Cerium oxyde, okiside ya fer, nizindi scavengers zibuza okiside gukomera kwumunyururu wa siloxane no kwangirika kwumugongo munsi yubushyuhe bwinshi. Iyi antioxydants yongerera igihe cya serivisi kuri 260 ° C.

2. Amashanyarazi yuzuye

nini , alumina Nitride ya aluminium , nibindi, ikwirakwiza vuba ubushyuhe kugirango igabanye ubushyuhe bwimbere kandi itinde gusaza. Ibi nibyingenzi byingenzi mubisabwa aho kaseti ikoreshwa nkubushyuhe bwumuriro cyangwa aho ubushyuhe bwiyongera kuva muri substrate bushobora kwihuta kwangirika.

Abuzuza bose bakeneye passivation yo hejuru cyangwa kuvura silane kugirango birinde modulus ikabije no gukomera gukomera kubushyuhe buke.

Incamake - Umuyoboro uhuza imiterere ikabije

Icyuma gifata ubushyuhe-buringaniye bwa kaseti ya PTFE mubyukuri ni platine-catisale yongeyeho guhuza imiyoboro ya microphase itandukanijwe yashyizwemo na MQ resin ya chimique ya chimique hamwe na silibike ya Hybride ya fenyl. Binyuze kuri gradient ihuza hamwe na tekinoroji yo guhuza, ihuza neza:

• Kwihuta cyane no guhinduka cyane mubushyuhe buke

• Gukomera hamwe no kurwanya anti-okiside ku bushyuhe bwinshi

… Muburyo bumwe bworoshye bwa elastique, bujuje ibyagutse-ubushyuhe-buringaniye busabwa.

Aokai PTFE ikora kaseti ya PTFE yubushyuhe bugari ukoresheje ubu buryo bwa sisitemu. Ibisobanuro byihariye - harimo ubunini, guhuza ibice, no kuzuza ibintu - birahari kubikenewe byihariye.

Iyi ngingo ya tekiniki yatanzwe na Jiangsu Aokai Ibikoresho bishya byikoranabuhanga Co, Ltd.

Niba wifuza kumenya ibisobanuro birambuye, ibintu byakoreshejwe hamwe nibisubizo byabigenewe kumurongo wuzuye wibicuruzwa, harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE, imikandara ya meshi ya PTFE, imikandara yimashini idahwitse, umwenda wuzuye wa PTFE, umukandara utwara ubushyuhe bukabije hamwe numuyoboro mwinshi wa fiberglass, nyamuneka twandikire.
