Grafting hloov kho ntawm chloroprene roj hmab (CR) cuam tshuam qhov tsis tu ncua ntawm CR molecular qauv, ua rau nws tsis tshua muaj crystallization thiab tiv thaiv qis -kub gelation, yog li ua rau cov nplaum ua kom txias. Grafted adhesives muaj lub sij hawm ntev tack tuav thiab tsis tshua muaj kev ua kom kub, ua rau lawv haum rau ob qho tib si automated loj ntau lawm thiab phau ntawv ua haujlwm, ua rau kev loj hlob sai hauv Asia. Nyiv, Eastern Europe, Australia, thiab cov teb chaws Esxias sab hnub tuaj Asia feem ntau siv hloov kho grafted CR adhesives rau khau. Hauv kuv lub tebchaws, 95% ntawm cov chaw tsim khau siv ob qho tib si thiab grafted CR adhesives, tab sis kev siv grafted CR adhesives tseem me me, suav txog li 10% ntawm tag nrho cov CR adhesives.
Cycloprene roj hmab / methyl methacrylate (MMA) binary grafted adhesive yog tam sim no feem ntau siv grafted hloov kho CR nplaum. Sab chains ntawm PMMA muaj qhov zoo sib xws ntawm solubility tsis muaj zog thiab lub zog tsis muaj zog rau cov khoom sib txuas PVC, yooj yim tsim cov txheej txheem diffusion. Hais txog cov kua qaub- hauv paus kev sib koom ua ke, PMMA, muaj cov ester pawg, yog alkaline, thaum PVC, vim muaj Cl atoms, yog acidic, uas kuj txhawb kev sib raug zoo ntawm kev hloov kho CR nplaum rau PVC cov ntaub ntawv. Qhov tseem ceeb tshaj, homopolymerized PMMA muaj kev sib raug zoo nrog plasticizers (esters) hauv PVC hloov tau, yog li daws qhov ntev - sawv cev qhov teeb meem ntawm tsis tuaj yeem sib txuas cov yas PVC. Kev tshawb fawb hauv cheeb tsam no yog tam sim no paub tab.
