Dɛn ne nnyinasosɛm a ɛfa adhesion of PTFE tape ho?

PTFE teyp a Jiangsu Aokai New Materials, a ɛyɛ PTFE teyp a ɛyɛ adwumaden no yɛ no de silicone a wɔde nkata so a ɛma nhyɛso (silicone PSA) di dwuma . Silicone PSA a ɛbata ho no di amansan anammɔn abiɛsa a ɛwɔ PSA mu no akyi: wetting – adsorption – cohesion , nanso ne kwan a wɔfa so yɛ no yɛ soronko:

1. Wetting ne honam fam adsorption

Silicone PSA a ɛwɔ PTFE tape mu no yɛ nea wɔde afrafra:

·  Silicone rɔba  (ɛma ɛyɛ mmerɛw na ɛyɛ mmerɛw) .

·  MQ silicone resin  (ɛma ɛyɛ den na ɛyɛ tack) .

Wɔ nhyɛso a emu yɛ hare ase no, silicone rɔba nkɔnsɔnkɔnsɔn a ɛyɛ mmerɛw no sen ntɛmntɛm ma ɛyɛ nwini wɔ micro rough surface a ɛwɔ substrate no so. Honam fam adsorption nam van der Waals tumi  ne hydrogen nkitahodi fã bi so na ɛba.

2. 'Po supɔw' nhyehyɛe: mpaapaemu a ɛbata ne nkabom

Eyi ne ɔkwan a ɛda nsow sen biara a silicone PSA fa so yɛ adwuma wɔ PTFE teyp mu:

·  MQ resin (the 'nsupɔw') : rigid abiɛsa afã cage te sɛ structures apete wɔ adhesive layer. Wɔma adhesion  – silanol akuw (Si–OH) a ɛwɔ MQ resin so no ne nneɛma a ɛwɔ soro te sɛ ahwehwɛ, dade, ne silicone rɔba yɛ nkitahodi a emu yɛ den.

·  Silicone rɔba (the 'po') : polymer phase a ɛkɔ so a ɛma ahoɔden a ɛka bom  a ɛbɛko atia emu huammɔdi bere peeling.By nsakraeɛ ratio a MQ resin ne silicone rɔba, tack  ne peel ahoɔden  betumi pɛpɛɛpɛ kari pɛ.

3. Crosslinked network ma biakoyɛ yɛ kɛse

Bere a wɔresa anaasɛ wɔreyɛ no, wɔde na ɛkyekyere silicone rɔba nkɔnsɔnkɔnsɔn no wɔ ɔkwan a ɛfata so peroxides  anaa platinum catalysts  de yɛ ntam a ɛwɔ afã abiɛsa. Eyi hwɛ hu sɛ ade a wɔde nkata so no bɛfa ntam a ɛho tew a wɔde yiyi mu  sen sɛ ɛbɛka abom  (abubu wɔ ntama no mu) wɔ nhyɛso ase.

Tɔfabɔ

PTFE tape a ɛbata ho no yɛ adwuma sɛnea edidi so yi:

·  Silicone rɔba ma ɔfasu no yɛ nsu na ɛma honam fam adsorption denam van der Waals tumi so.

·  MQ resin ('nsupɔw') ma adhesion; silicone rɔba ('po') ma biakoyɛ.

·  Crosslinking a ɛkɔ fam no hyɛ biakoyɛ mu den na esiw emu adhesive huammɔdi ano.
