Ndeipi musimboti wekunamatira wePTFE tepi?

Iyo PTFE tepi inogadzirwa naJiangsu Aokai New Materials, inyanzvi yekugadzira PTFE tepi, inoshandisa silicone pressure-sensitive adhesive (silicone PSA) . Iko kunamatira kwesilicone PSA kunotevera matanho matatu epasirese ePSA: wetting - adsorption - cohesion , asi maitiro ayo akasiyana:

1. Wetting uye muviri adsorption

Iyo silicone PSA yePTFE tepi musanganiswa we:

·  Silicone rabha  (inopa kuchinjika uye kupfava)

MQ  silicone resin  (inopa kuomarara uye tack)

Pasi pekumanikidzwa kwechiedza, iyo inochinjika silicone rabha cheni inoyerera nekukurumidza kunyorovesa iyo micro rough pamusoro peiyo substrate. Kushambadza kwemuviri kunoitika kuburikidza nevan der Waals masimba  uye chikamu chehydrogen bond.

2. 'Sea Island' chimiro: kupatsanurwa kwekunamatira uye kubatana

Iyi ndiyo yakasarudzika nzira yesilicone PSA muPTFE tepi:

MQ  resin ('zvitsuwa') : yakaoma mativi matatu keji senge zvimiro zvakaparadzirwa mune inonamira layer. Vanopa adhesion  - mapoka e silanol (Si-OH) paMQ resin anoumba kudyidzana kwakasimba nenzvimbo dzakaita segirazi, simbi, uye silicone rabha.

·  Silicone rabha ('gungwa') : iyo inoenderera yepolymer chikamu chinopa simba rakabatana  kuramba kutadza kwemukati panguva. Nekugadzirisa chiyero cheMQ resin kune silicone rabha, tack  uye peel simba  rinogona kunyatsoenderana.

3. Crosslinked network inowedzera kubatana

Munguva yekurapa kana kugadzira, silicone rabha cheni dzakachinjika zvine mwero uchishandisa peroxides  kana platinamu catalysts  kuti iite matatu dimensional network. Izvi zvinovimbisa kuti iyo inonamira layer inopinda yakachena interfacial peeling  pane yakabatana kutadza  (kutsemuka mukati mekunamatira) pasi pekunetseka.

Summary

Iko kunamatira kwePTFE tepi kunoshanda sezvinotevera:

·  Silicone rabha inonyorovesa pamusoro uye inopa kushambadza kwemuviri kuburikidza nemauto evan der Waals.

MQ  resin ('zvitsuwa') inopa adhesion; silicone rubber ('gungwa') inopa kubatana.

·  Pakati pepakati crosslinking inosimbisa kubatana uye inodzivirira mukati adhesive kutadza.
