Dab tsi yog lub hauv paus ntsiab lus ntawm adhesion ntawm PTFE daim kab xev?

PTFE daim kab xev tsim los ntawm Jiangsu Aokai Cov Khoom Tshiab, cov chaw tsim khoom ntawm PTFE daim kab xev, siv silicone siab-rhiab nplaum nplaum (silicone PSA) . Lub adhesion ntawm silicone PSA ua raws li peb lub universal kauj ruam ntawm PSA: wetting - adsorption - cohesion , tab sis nws cov txheej txheem yog tshwj xeeb:

1. Wetting thiab lub cev adsorption

Silicone PSA ntawm PTFE daim kab xev yog kev sib xyaw ntawm:

·  Silicone roj hmab  (muab yooj yooj yim thiab softness)

·  MQ silicone resin  (muab rigidity thiab tack)

Nyob rau hauv lub teeb siab, lub saj zawg zog silicone roj hmab chains ntws ceev ceev kom ntub cov micro ntxhib nto ntawm lub substrate. Lub cev adsorption tshwm sim ntawm van der Waals rog  thiab ib nrab hydrogen bonds.

2. 'Hiav txwv Island' qauv: sib cais ntawm adhesion thiab cohesion

Nov yog qhov tshwj xeeb tshaj plaws ntawm silicone PSA hauv PTFE daim kab xev:

·  MQ resin ( 'Islands') : rigid peb seem tawb zoo li cov qauv dispersed nyob rau hauv cov nplaum txheej. Lawv muab adhesion  - cov pab pawg silanol (Si-OH) ntawm MQ resin tsim muaj kev cuam tshuam nrog cov chaw xws li iav, hlau, thiab silicone roj hmab.

·  Silicone roj hmab ( ' hiav txwv ') : lub nruam polymer theem uas muab cohesive zog  los tiv thaiv sab hauv tsis ua hauj lwm thaum lub sij hawm peeling.Los ntawm kev kho qhov sib piv ntawm MQ cob rau silicone roj hmab, tack  thiab tev lub zog  tuaj yeem sib npaug.

3. Crosslinked network txhawb kev sib koom ua ke

Thaum lub sij hawm kho los yog tsim, silicone roj hmab chains yog nruab nrab crosslinked siv peroxides  los yog platinum catalysts  los ua ib tug peb seem network. Qhov no ua kom ntseeg tau tias cov nplaum nplaum ua rau lub ntsej muag huv huv  es tsis ua kom tsis sib haum  (kev tawg hauv cov nplaum) hauv kev ntxhov siab.

Cov ntsiab lus

Lub adhesion ntawm PTFE daim kab xev ua haujlwm raws li hauv qab no:

·  Silicone roj hmab ntub rau saum npoo thiab muab lub cev adsorption ntawm van der Waals rog.

·  MQ resin ('Islands') muab adhesion; silicone roj hmab (' hiav txwv ') muab kev sib koom ua ke.

·  Nruab nrab crosslinking ntxiv dag zog rau cohesion thiab tiv thaiv tsis ua hauj lwm hauv cov nplaum.
