Uyini umgomo wokunamathela we-PTFE tape?

Itheyiphu ye-PTFE ekhiqizwe i-Jiangsu Aokai New Materials, umkhiqizi ochwepheshile we-PTFE tape, isebenzisa i-silicone ezwela ukucindezela (i-silicone PSA) . Ukunamathela kwe-silicone PSA kulandela izinyathelo ezintathu zomhlaba jikelele ze-PSA: ukumanzisa - i-adsorption - cohesion , kodwa indlela yayo ihlukile:

1. Ukumanzisa nokukhanyiswa ngokomzimba

I-silicone PSA ye-PTFE tape iyinhlanganisela yalokhu:

·  Irabha ye-Silicone  (ihlinzeka ngokuguquguquka nokuthamba)

·  I-MQ silicone resin  (ihlinzeka ngokuqina kanye ne-tack)

Ngaphansi kwengcindezi yokukhanya, amaketango erabha e-silicone aguquguqukayo ageleza ngokushesha ukuze amanzise indawo encane emagebhugebhu ye-substrate. I-adsorption ebonakalayo yenziwa ngamandla e-van der Waals  ayingxenye namabhondi e-hydrogen .

2. Isakhiwo 'sesiqhingi sasolwandle': ukuhlukaniswa kokunamathela nokuhlangana

Lena indlela ehluke kakhulu ye-silicone PSA ku-PTFE tape:

·  I-MQ resin ('iziqhingi') : ikheji eliqinile elinezinhlangothi ezintathu njengezakhiwo ezihlakazeke kungqimba olunamathelayo. Ahlinzeka ngokunamathela  - amaqembu e-silanol (Si-OH) ku-MQ resin enza ukusebenzisana okuqinile nezindawo ezifana nengilazi, insimbi, nerabha ye-silicone.

·  Irabha ye-Silicone ('ulwandle') : isigaba se-polymer esiqhubekayo esinikeza amandla ahlangene  okumelana nokwehluleka kwangaphakathi ngesikhathi Ukucwecwa.Ngokulungisa isilinganiso se-MQ resin nerabha ye-silicone, okuthawula  nawokucwecwa amandla  angalinganiswa ngokunembile.

3. Inethiwekhi ye-Crosslinked ithuthukisa ukuhlangana

Ngesikhathi sokwelapha noma sokukhiqiza, amaketanga erabha ye-silicone ahlanganiswa ngokumaphakathi kusetshenziswa ama-peroxides  noma ama-catalysts eplatinamu  ukuze akhe inethiwekhi enezinhlangothi ezintathu. Lokhu kuqinisekisa ukuthi ungqimba lwe-adhesive lubhekana nokucwenga okuhlanzekile kwe-interfacial  kunokuhluleka okuhlangene  (ukuphuka ngaphakathi kwe-adhesive) ngaphansi kokucindezeleka.

Isifinyezo

Ukunamathela kwe-PTFE tape kusebenza kanje:

·  Irabha ye-Silicone imanzisa indawo futhi inikeza ukukhangiswa ngokomzimba ngokusebenzisa amandla e-van der Waals.

·  I-MQ resin ('iziqhingi') inikeza ukunamathela; irabha ye-silicone ('ulwandle') inikeza ukuhlangana.

·  Ukuxhumanisa okumaphakathi kuqinisa ukuhlangana futhi kuvimbela ukwehluleka kwangaphakathi kokunamathela.
