Kev kho kom zoo txhais tau qhov kawg kev sib txuas ua haujlwm ntawm cov adhesives. Rau kev tsim khau, rooj tog tsim khoom thiab lwm yam xwm txheej hauv kev lag luam, kev nkag siab txog cov nplaum tawv tawv thiab cov khoom siv kho kom zoo pab cov tuam txhab tsim kho cov txheej txheem ntau lawm thiab txo cov kev pheej hmoo ntawm kev sib koom ua ke.
Adhesive curing yog feem ntau saum ob hom:Physical curing thiab Chemical curing. Kev kho lub cev yog los ntawm cov kuab tshuaj volatilization lossis dej evaporation. Tshuaj tua kab mob yuav siv sij hawm qhov chaw thaum resin Cheebtsam nyob rau hauv adhesives reacts nrog curing agents los tsim peb-dimensional txuas tes hauj lwm. Cov txheej txheem no hloov cov kua los yog cov kab sib txuas ua ke rau hauv cov khoom muaj zog siab. Kev sib txuas zoo heev txhim kho cov neeg kho tshuab lub zog, tiv thaiv tshav kub, tiv thaiv dej thiab tiv thaiv corrosion ua haujlwm ntawm cov nplaum nplaum tiav.
Curing agents yog cov khoom siv tseem ceeb hauv ob feem ntawm cov nplaum nplaum. Lawv lub luag haujlwm tseem ceeb suav nrog kev ua kom muaj kev sib txuas sib txuas nrog cov pab pawg nquag xws li epoxy pawg thiab hydroxyl pawg ntawm resin molecules los tsim cov qauv tsis sib xws thiab infusible network. Ntxiv nrog rau kev txhim kho kev sib raug zoo ntawm kev sib raug zoo thiab kev hnav tsis kam, cov neeg ua haujlwm raug xaiv kom raug kho kom zoo rau cov dej kub-tshuaj lom neeg. Lawv kuj tswj cov gel lub sij hawm thiab kho qhov kub thiab txias kom haum rau ntau hom kev tsim khoom.
Feem ntau-siv industrial curing agents npog ntau pawg. Amine-raws li curing agents suav nrog aliphatic diamines, polyamines thiab aromatic polyamines yog dav txuam nrog epoxy resins nrog ntau yam curing-temperature thiab heat-resistance profiles. Acid-type curing agents muaj cov organic acids, acid anhydrides thiab boron trifluoride complexes rau cov kab ke tshwj xeeb. Peroxides thiab isocyanates tsim cov txheej txheem ruaj khov los ntawm cov dawb radicals lossis ntxiv cov tshuaj tiv thaiv rau cov tshuaj tua kab mob. Tshwj xeeb-formulated curing agents rau polyurethane thiab PVAc systems txhim kho kev ua tau zoo rau dispersion-raws li thiab hnyav-borne adhesives thiab txhawb kev sib faib ntawm qhov chaw sib xyaw raws li qhov xav tau tiag tiag.
Xaiv cov nplaum uas tsim nyog thiab cov tshuaj tua kab mob ua ke nrog kev tswj hwm ib puag ncig uas tsim nyog yuav ua rau kev sib raug zoo rau kev tsim khoom loj thiab kev siv dav dav.
