Ukwakheka Kwezingxenye Ezihlukene Zendwangu Ye-PTFE Esezingeni Eliphezulu: Ingabe Kukhona Ungqimba Olushintshayo Phakathi Kwe-PTFE Coating kanye Ne-Fiberglass Substrate?

I-Jiangsu Aokai New Materials, umkhiqizi ochwepheshe wendwangu ye-PTFE eshisa kakhulu, ikulethela imininingwane ejulile. Njengempahla eyinhlanganisela esebenza kahle kakhulu, ukwakheka okuncanyana okuncane kwe-PTFE indwangu eshisa kakhulu ibalulekile ekuphikeleni kwayo kwezinga lokushisa, amandla ekhasi kanye nokuguquguquka. Enqubweni yokukhiqiza yendwangu ye-PTFE enezinga eliphezulu lokushisa, kukhona ungqimba  olubalulekile loshintsho phakathi kwe-PTFE enamathelayo ne-fiberglass substrate. Ngaphandle kwalesi sendlalelo soguquko, ubuqotho besakhiwo obuhlanganisiwe bendwangu ye-PTFE yezinga lokushisa eliphezulu abukwazi ukufezwa.

Ngokuhlaziywa kwe-microscopic yezingxenye ezihlukene, lolu ungqimba lwenguquko alukhiwanga ikhemikhali eyodwa, kodwa indawo ehlanganisa ubuso eyinhlanganisela eyakhiwe ngezindlela eziningi zokuguqula amakhemikhali namakhemikhali. Indlela yokwakheka nokwakheka kwesendlalelo soguquko kunemininingwane ngale ndlela elandelayo:

1. I-Silane Coupling Agent Bonding Layer

I-fiberglass engaphenduliwe ayikwazi ukubopha ngokuqondile ne-PTFE resin. Ngakho-ke, indwangu ye-fiberglass kufanele iguqulwe ngama-agent e-silane coupling ekukhiqizeni. Esinye isiphetho se-ejenti ehlanganisayo sisabela ngamakhemikhali namaqembu e-silanol (Si-OH) endaweni ye-fiberglass, kuyilapho esinye isiphetho siqukethe amaqembu asebenzayo anokusondelana okuphezulu noma ukuphinda kusebenze ku-fluororesin. Isebenza njengebhuloho elixhumanisa amakhemikhali phakathi kohlaka lwamathambo e-fiberglass kanye ne-PTFE enamathelayo, lolu sendlalelo luhlinzeka nge-anchorage yamakhemikhali eyisisekelo ekukhanyeni okupheleleyo kwesakhiwo.

2. I-Hot-Melt Adhesive Intermediate Layer

Ekubonweni kwesigaba esiphambanayo kwendwangu yezinga eliphezulu lezinga lokushisa eliphezulu ye-PTFE, ungqimba olushintshayo lwe-gradient oluqukethe i-PFA (Perfluoroalkoxy alkane) noma i-FEP (Fluorinated Ethylene Propylene) ingabonwa ngokucacile phakathi kwe-PTFE enamathelayo ne-fiberglass substrate. Ngesikhathi sokushisa okuphezulu kwe-sintering, lawa ma-fluoroplastics ancibilikayo asebenza njengezinamatheliso ezincibilikayo zangaphakathi, ezingena futhi zigoqe izinqwaba ze-fiberglass ukuze zakhe isigaba esiqhubekayo. Lesi sendlalelo esimaphakathi sivimbela ngempumelelo ukugoba okuphindaphindiwe ngaphansi kwezimo zokugoba nokuguquguquka.

3. I-Mechanical Interlocking Interface

Indwangu ye-PTFE enezinga eliphezulu lokushisa ikhiqizwa ngokusebenzisa izinqubo eziningi zokufakela nokuhlanganisa. Ngokwe-Microscopically, i-emulsion ye-PTFE ingena ezimbotsheni ezinosayizi omncane we-micron ezakhiwe i-warp ne-weft yendwangu yezindwangu ze-fiberglass. Ngemva kokucwiliswa nokuphulukiswa, inhlaka ye-PTFE eqinile yakha isakhiwo sokubambelela esinezinhlangothi ezintathu esiqinile ngendwangu yefayibha. Lesi sakhiwo esixhumene ngokomzimba siletha ukwesekwa kwemishini okuthembekile, okuqinisekisa ukuzinza kwe-dimensional kanye nokusebenza okuphikisana nokuchithwa kwenkonzo yesikhathi eside.

4. I-Gradient Buffer Interface

I-PTFE enamathelayo ne-fiberglass ifaka ama-coefficients ahluke kakhulu wokunwetshwa okushisayo, okudala kalula ingcindezi yangaphakathi ngaphansi kwemijikelezo yokushisisa nokupholisa okusheshayo. Indwangu ye-Premium ye-PTFE enezinga lokushisa eliphezulu yamukela ukwakheka kwe-gradient: indawo eseduze ne-fiberglass inothe ngezinto ezinamathelayo ezimelana nokushisa kanye ne-FEP, kuyilapho ubumsulwa be-PTFE bukhula kancane kancane bubheke endaweni engaphandle. Lesi sakhiwo se-gradient sivimbela ukucindezeleka okushisayo ngaphansi kwezimo zokushisa okuphezulu futhi sigwema ukuqhekeka kwendawo yokumboza.

5. I-Substrate Pretreatment Interface

Ngaphambi kokwakha izendlalelo zoguquko ezingenhla, indwangu ye-fiberglass kufanele ikhishwe nge-high-temperature dewaxing kanye nokufisa ukususa ama-ejenti wokulinganisa izindwangu kanye nokungcola. Lesi sinyathelo sokwelashwa sangaphambi kwesikhathi esiyinhloko sidalula amaqembu e-silanol asebenzayo endaweni yefayibha, enikeza isixhumi esibonakalayo esihlanzekile nesisebenza ngamakhemikhali sokwelashwa okuhlanganisayo okulandelayo kanye nokungena kwe-resin.

Ukwakheka kwezingxenye eziphambanayo zendwangu ye-PTFE yokushisa okuphezulu kwakha isistimu eyinhlanganisela ephelele evezwa ukubopha okuqinile, ukungena kwe-gradient kanye nengaphezulu elihlanzekile elisebenzayo le-resin . Izuza kusukela ezingqimbeni zezinguquko zemisebenzi eminingi ezihlanganiswe ukuvaleka ngokomzimba nokubopha kwamakhemikhali, impahla igcina impahla yokukhululwa ehle kakhulu kanye nokumelana nokugqwala kwe-PTFE, kuyilapho ithola amandla avelele okuqina kanye nokumelana nokukhathala.

Okuqukethwe okungenhla kunikezwa i- Jiangsu Aokai New Material Technology Co., Ltd.

Sinikeza uhla olugcwele lwemikhiqizo ehlanganisa indwangu ye-PTFE yokushisa okuphezulu, itheyiphu ye-PTFE yokushisa okuphezulu, ibhande le-PTFE elinezikhala elisezingeni eliphezulu, ibhande lomshini wokuhlanganisa elingenamthungo, indwangu eboshwe ohlangothini olulodwa lwe-PTFE, ibhande lokuthutha elimelana nezinga eliphezulu kanye nendwangu ye-fiberglass ekwazi ukumelana nokushisa okuphezulu. Ukuze uthole imingcele enemininingwane yomkhiqizo, izixazululo zohlelo lokusebenza nezinsizakalo ezenziwe ngezifiso, sicela usithinte:
