Txhim kho kev sib txuas lus

Los ntawm kev txhim kho qhov permeability thiab ntub dej ntawm cov txheej rau lub substrate, cov txheej tuaj yeem nkag mus rau hauv cov qhov thiab cov kab nrib pleb ntawm lub substrate ntau li ntau tau. Tom qab khov, ntau lub anchors me me tau tsim los tuav lub substrate kom ruaj khov, yog li txhim kho qhov lo ntawm cov zaj duab xis txheej rau lub substrate.

Txhim kho Van Der Waals lub zog

Raws li kev xam, thaum qhov deb ntawm ob lub dav hlau yog 1 nm, lub zog van der Waals tuaj yeem ncav cuag 9.81 ~ 98.1 MPa. Los ntawm kev txhim kho qhov ntub ntawm cov txheej rau lub substrate, cov txheej tuaj yeem ntub kom tag nrho li sai tau thiab ze rau qhov chaw substrate ua ntej kho, yog li ua rau lub zog van der Waals nce ntxiv thiab thaum kawg txhim kho qhov nplaum ntawm cov zaj duab xis txheej rau lub substrate.

Muab cov pab pawg reactive thiab tsim cov xwm txheej rau kev tsim cov hydrogen bonds thiab cov tshuaj bonds

Lub zog ntawm cov hydrogen bonds thiab cov tshuaj sib txuas yog muaj zog dua li ntawm van der Waals forces. Cov neeg txhawb nqa kev sib txuas xws li cov resins thiab cov neeg sawv cev sib txuas muab cov pab pawg reactive xws li amino, hydroxyl, carboxyl lossis lwm cov pab pawg nquag, uas tuaj yeem tsim cov hydrogen bonds lossis cov tshuaj sib txuas nrog cov pa oxygen lossis hydroxyl pab pawg ntawm qhov chaw ntawm lub substrate, yog li txhim kho kev sib txuas.

Kev sib kis

Thaum cov khoom siv coated yog cov khoom polymer, cov kuab tshuaj muaj zog lossis chlorinated polyolefin resin adhesion promoter tuaj yeem siv tau. Nws tuaj yeem txhawb kev sib kis thiab kev yaj ntawm cov txheej thiab cov khoom siv substrate, thaum kawg ua rau qhov interface ploj mus, yog li txhim kho kev sib txuas ntawm cov zaj duab xis txheej thiab cov khoom siv substrate.
