Gịnị bụ ụkpụrụ nke adhesion nke PTFE teepu?

Teepu PTFE nke Jiangsu Aokai New Materials mepụtara, onye ọkachamara na-emepụta teepu PTFE, na-eji nrapado nrụgide silicone (silicone PSA) . Adhesion nke silicone PSA na-agbaso usoro atọ zuru ụwa ọnụ nke PSA: wetting – adsorption – cohesion , mana usoro ya pụrụ iche:

1. Wetting na anụ ahụ adsorption

PSA silicone nke teepu PTFE bụ ngwakọta nke:

(  Rubber silicone  na-enye mgbanwe na ịdị nro)

MQ  resin silicone  (na-enye ike na tack)

N'okpuru nrụgide ọkụ, ụdọ rọba silicone na-agbanwe agbanwe na-agba ọsọ ọsọ iji mee ka mmiri dị n'elu ala ahụ siri ike. Mgbasa ozi anụ ahụ na-apụta site na ndị agha van der Waals  na njikọ nke akụkụ hydrogen.

2. 'Agwaetiti oké osimiri' Ọdịdị: nkewa nke adhesion na ịdị n'otu

Nke a bụ usoro pụrụ iche nke silicone PSA na teepu PTFE:

Resin MQ  ('agwaetiti') : ọnụ ụlọ akụkụ atọ siri ike dị ka ihe agbasasịworo na oyi akwa nrapado. Ha na-enye adhesion  - otu silanol (Si-OH) na MQ resin na-eme mmekọrịta siri ike na elu dị ka iko, metal, na silicone roba.

Rubber silicone  ('oké osimiri') : usoro polymer na-aga n'ihu nke na-enye ike jikọtara ọnụ  iji guzogide ọdịda ime n'oge. peeling.By ukpụhọde ruru nke MQ resin ka silicone roba, tack  na bee ike  nwere ike kpomkwem itule.

3. Crosslinked netwọk na-eme ka njikọ dị n'otu

N'oge ọgwụgwọ ma ọ bụ n'ichepụta, a na-ejikọta ụdọ silicone rọba nke ọma site na iji peroxides  ma ọ bụ platinum catalysts  iji mepụta netwọk akụkụ atọ. Nke a na-eme ka o doo anya na oyi akwa nrapado na-enweta peeling interface dị ọcha  kama ịdakọta ọnụ  (njiji n'ime nrapado) n'okpuru nrụgide.

Adhesion nke PTFE teepu na-arụ ọrụ dị ka ndị a:

Ihe rọba silicone  na-ehicha elu ma na-enye mgbasa ozi anụ ahụ site na ndị agha van der Waals.

·  MQ resin ('agwaetiti') na-enye adhesion; rọba silicone ('oké osimiri') na-enye njikọ.

·  Njikọta dị oke ala na-ewusi njikọta ike ma na-egbochi ọdịda nrapado nke ime.
