Tshuaj tiv thaiv tshuaj lom neeg ntseeg hais tias nyob rau hauv kev sib txuas ua ke ntawm kev sib txuas ntawm cov nplaum thiab cov kab sib khi, nws muaj qee zaum cov tshuaj bonds, xws li cov khoom sib txuas ntawm cov nplais thiab cov xim tooj hlau, cov nyom ntawm tus neeg sawv cev ntawm kev sib txuas, isocyanate rau hlau thiab roj hmab. Cov kev tshawb fawb xws li interfaces tau pom tias tsim muaj cov tshuaj bonds. Txawm li cas los xij, kev tsim cov tshuaj bonds tsis yog sib txawv, thiab nws tsim nyog tsim ib daim ntawv cog lus rau cov qoob loo, kom tsis muaj peev xwm tsim ib qho kev sib haum ntawm qhov sib tiv tauj ntawm cov nplaum thiab lub qab. Ntxiv mus, pes tsawg tus cov tshuaj bonds ib chav adhesion interface yog ntau tsawg dua cov kev sib tshuam ntawm kev sib nkag siab, vim li ntawd lub zog ntawm qhov kev sib txuas ntawm cov roj molecules tsis poob siab.
Tus neeg sawv cev tseem ceeb yog qhov tseem ceeb ntawm cov nplaum, uas yog cov khoom sib txuas ua ke thiab yog ib qho tseem ceeb qhia txog qhov txawv ntawm cov nplaum. Tus neeg sawv cev tseem ceeb feem ntau yog tsim los ntawm ib lossis ob los yog peb hom polymers siab, thiab nws yuav tsum muaj kev nplua thiab kev ntub dej. Cov tshuaj yeeb dej caw uas siv tau los ua cov tshuaj nplaum yog:
1. Ntuj polymers, xws li hmoov nplej, cellulose, tannin, gum arabic thiab sodium alginate thiab lwm yam kev ua los ntawm cov nroj tsuag, thiab cov tsiaj ua zoo xws li pob txha yas, ntses cov gelatin, ntshav kua nplaum, rooj plaub thiab lub plhaub taum.
2. Khoom cua hluavtaws, muab faib ua ob qho loj ntawm cov thermosetting cob thiab thermoplastic cob. Cov thermosetting cov khoom xws li epoxy, phenolic, polyester polyester, polyurethane, silicone, polyimide, bismaleimide, allyl resin, furan cob, amino cob, alkyd cob, lwm yam .; thermoplastic polyester, polyphenylene ether, fluororein, polyphenylene sulfide, polysulfone, polyketone, polyphenyl ester, kua siv lead ua kua polymer, thiab lwm yam zoo li, xws li polyethylene, polypropylene, polyvinyl chloride, polystyrene, acrylic resin, nylon, polycarbonate, hloov cov resins lossis polymer alloys thereof. Nws yog hom siv ntau hom nplaum.
3. Roj Hmab thiab Elastomer. Cov roj hmab tsuas yog muaj cov roj hmab, cov roj ntsha roj nitrile ethylene propylene rubber, fluorine roj hmab, polyisobutylene, polysulfide roj hmab, ntuj roj hmab, chlorosulfonated polyethylene roj hmab, etc .; tus elastomer yog cov thermoplastic elastomer thiab polyurethane elastomer.
4. Tsis tas li ntawd, muaj cov tshuaj tsis haum xws li cov tshuaj silicates, phosphates, thiab phosphoric acid-copper oxide.
