Ulwakhiwo olunqamlezileyo lwelaphu le-PTFE lobushushu obuphezulu: Ngaba kukho iNqanaba loTshintsho phakathi kwe-PTFE yoKutyabeka kunye neSubstrate ye-Fiberglass?

I-Jiangsu Aokai New Materials, umenzi oqeqeshiweyo we-PTFE ilaphu lobushushu obuphezulu, ukuzisa ulwazi olunzulu. Njengomgangatho 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 maleko wenguqu, ingqibelelo yesakhiwo edibeneyo ye-PTFE yelaphu lobushushu obuphezulu ayinakufezekiswa.

Ngohlalutyo lwe-microscopic yamacandelo anqamlezayo, olu maleko wenguqu aluqulunqwanga ngento enye yekhemikhali, kodwa indawo edibeneyo yobuso eyakhiwe ngeendlela ezininzi zokuguqula umzimba kunye neekhemikhali. Indlela yokwakheka kunye nokwakheka 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 elinye isiphelo liqulethe amaqela asebenzayo kunye nobudlelwane obuphezulu okanye ukuphinda kusebenze kwi-fluororesins. Isebenza njengebhulorho yokuhlangana kweekhemikhali 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 kakhulu yokwandiswa kwe-thermal, eyenza lula uxinzelelo lwangaphakathi phantsi komjikelo wokufudumeza okukhawulezayo kunye nokupholisa. Ilaphu lePremium PTFE elinobushushu obuphezulu lithatha ubume bethayiphu edityanisiweyo: indawo ekufutshane nefiberglass ityebile kwizinto ezincamathelayo 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 wengubo.

5. I-Substrate Pretreatment Interface

Phambi kokwakha iileya zotshintsho ezingentla, ilaphu le-fiberglass kufuneka lenziwe i-dewaxing yobushushu obuphezulu kwaye linqwenele ukususa ii-agent zesayizi ye-textile kunye nokungcola. Eli nyathelo liphambili lonyango libonisa amaqela e-silanol asebenzayo kumphezulu wefayibha, ebonelela ngojongano olucocekileyo nolwekhemikhali olusebenzayo kunyango lokudityaniswa 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 nokubopha imichiza, izinto eziphathekayo zigcina ipropathi ebalaseleyo yokukhupha kunye nokumelana nokubola kwe-PTFE, ngelixa ifumana amandla abalaseleyo kunye nokumelana nokukhathala.

Lo mxholo ungasentla unikwe nguJiangsu Aokai New Material Technology Co., Ltd.
