Ulwakhiwo olunqamlezileyo lwelaphu le-PTFE lobushushu obuphezulu: Ngaba kukho iNguqu yeLale phakathi kwePTFE yoKutyabeka kunye neFiberglass Substrate?

I-Jiangsu Aokai New Materials, umenzi oqeqeshiweyo we-PTFE ilaphu lobushushu obuphezulu, ukuzisa ulwazi olunzulu. Njengomsebenzi ophezulu wezinto ezidibeneyo, i-microscopic cross-sectional structure ye-PTFE yobushushu obuphezulu belaphu ibaluleke kakhulu ekuxhathiseni ubushushu, amandla e-peel kunye nokuguquguquka. Kwinkqubo yokuveliswa kwelaphu lobushushu obuphezulu be-PTFE, kukho umaleko  obalulekileyo wotshintsho phakathi kwe-PTFE yokwambathisa kunye ne-fiberglass substrate. Ngaphandle kolu tshintsho lwenguqu, ingqibelelo yesakhiwo edibeneyo ye-PTFE yelaphu lobushushu obuphezulu ayinakufezekiswa.

Ngokuhlalutywa kwe-microscopic yamacandelo anqamlezayo, olu maleko wenguqu abunjwanga ngekhemikhali enye, kodwa indawo edibeneyo yobuso eyakhiwe ngeendlela ezininzi zokuguqula umzimba kunye neekhemikhali. Indlela yokwakheka kunye nokwakhiwa komaleko wotshintsho kuchazwe ngolu hlobo lulandelayo:

1. I-Silane Coupling Agent Bonding Layer

I-fiberglass engaphathwanga ayinakuhlangana ngokuthe ngqo ne-PTFE resin. Ke ngoko, ilaphu le-fiberglass kufuneka liguqulwe kunye neearhente zokudibanisa i-silane kwimveliso. Esinye isiphelo se-agent yokudibanisa i-chemically isabela kunye namaqela e-silanol (i-Si-OH) kumphezulu we-fiberglass, ngelixa esinye isiphelo siqulethe amaqela asebenzayo kunye nobudlelwane obuphezulu okanye i-reactivity kwi-fluororesins. Isebenza njengebhulorho yokudibanisa imichiza phakathi kwe-fiberglass skeleton kunye ne-PTFE yokwambathisa, olu maleko lubonelela ngesiseko se-anchorage yeekhemikhali kwi-lamination ye-structural lamination.

2. I-Hot-Melt Adhesive Intermediate Layer

Kwinqanaba elinqamlezayo lelaphu eliphezulu le-PTFE, i-gradient transition layer equkethe i-PFA (Perfluoroalkoxy alkane) okanye i-FEP (i-Fluorinated Ethylene Propylene) inokubonwa ngokucacileyo phakathi kwe-PTFE yokugqoka kunye ne-fiberglass substrate. Ngexesha lobushushu obuphezulu be-sintering, ezi fluoroplastics ezinyibilikayo zisebenza njengezinto zokuncamathelisa zangaphakathi ezishushu ezinyibilikayo, ukungena nokusonga iinyanda zefiberglass ukwenza isigaba esiqhubekayo. Olu luhlu oluphakathi luthintela ngokufanelekileyo i-delamination yokugqoka phantsi kweemeko zokugoba kunye nokuguquguquka okuphindaphindiweyo.

3. I-Mechanical Interlocking Interface

Ilaphu le-PTFE elinobushushu obuphezulu lenziwa ngokufaka izinto ezininzi kunye neenkqubo zokugquma. Ngokuncinci, i-emulsion ye-PTFE ingena kwi-micron-ubungakanani bepores ezenziwe yi-warp kunye ne-weft weaving yamalaphu e-fiberglass. Emva kokucoca kunye nokunyanga, i-PTFE resin eqinisiweyo yenza isakhiwo se-anchoring esine-dimensional ezintathu-dimensional mechanical anchoring kunye nelaphu lefiber. Esi sakhiwo sokudibanisa ngokomzimba sinikezela ngenkxaso ethembekileyo yomatshini, iqinisekisa ukuzinza kwe-dimensional kunye nokusebenza kwe-anti-delamination kwinkonzo yexesha elide.

4. I-Gradient Buffer Interface

I-PTFE yokwambathisa kunye ne-fiberglass ibonakalisa i-coefficients eyahlukileyo yokwandiswa kwe-thermal, eyenza lula uxinzelelo lwangaphakathi phantsi komjikelo wokufudumeza okukhawulezayo kunye nokupholisa. Ilaphu lePremium PTFE elinobushushu obuphezulu lithatha ubume bodidi oluhlanganisiweyo: indawo ekufutshane nefiberglass inezinamatheliso ezikwaziyo ukumelana nobushushu kunye ne-FEP, ngelixa ubunyulu be-PTFE bunyuka busiya kumphezulu ongaphandle. Esi sakhiwo se-gradient sithintela uxinzelelo lwe-thermal phantsi kweemeko zobushushu obuphezulu kwaye sinqanda ukuqhekeka komphezulu we-coating.

5. I-Substrate Pretreatment Interface

Phambi kokwakha iileya zotshintsho ezingentla, ilaphu le-fiberglass kufuneka lithotywe iqondo lobushushu obuphezulu kwaye linqwenele ukususa ii-agent zokulinganisa amalaphu kunye nokungcola. Eli nyathelo liphambili lonyango libonisa amaqela e-silanol asebenzayo kumphezulu wefayibha, ebonelela ngojongano olucocekileyo nolwekhemikhali olusebenzayo kunyango lokudibanisa okulandelayo kunye nokungena kwentlaka.

Ulwakhiwo olunqamlezileyo lwelaphu le-PTFE lobushushu obuphezulu lwenza inkqubo edibeneyo edibeneyo ebonakaliswe yi- bonding eyomeleleyo, ukungena kwe-gradient kunye ne-resin ecocekileyo esebenzayo . Ukuzuza kwiileya zenguqu ezisebenzayo ezininzi ezidityaniswe nokubanjwa komzimba kunye nokudibanisa imichiza, izinto eziphathekayo zigcina ipropathi ebalaseleyo yokukhululwa kunye nokuxhatshazwa kwe-corrosion ye-PTFE, ngelixa ifumana amandla abalaseleyo kunye nokuxhathisa ukukhathala.
