Dab tsi yog cov nplaum rau cov khoom sib txhuam?

All media materials that can connect the same or different types of materials together are called adhesives, also known as adhesives. It is an old and young science. The so-called "old" refers to the fact that thousands of years ago, humans began to use natural polymers such as animal glue and vegetable glue to bond products and production tools. Until the beginning of the last century, due to the appearance of various synthetic resins and synthetic rubbers, especially the successful production and commercialization of some representative polymers such as phenolic resin, epoxy resin, chloroprene rubber, nitrile rubber, etc., modern adhesives have The comprehensive properties of high strength, durability, and outstanding heat resistance have developed rapidly.

Cov txheej txheem tseem ceeb tsim los ntawm cov nplaum ntawm cov khoom sib txhuam yog cov hom roj hmab, hom roj hmab thiab cov khoom sib xyaw ntawm cov resin thiab roj hmab. Cov nplaum feem ntau yog ua los ntawm cov ntaub ntawv polymer, qee qhov yuav tsum tau ntxiv qee cov kuab tshuaj kom ua tiav qhov kev kho los ntawm kev siv tshuaj lom neeg lossis cov teebmeem ntawm lub cev, thiab kev kho tau qeeb qeeb thaum khaws cov nplaum. Yog li ntawd, cov nplaum nplaum muaj qee lub sijhawm khaws cia, uas cuam tshuam nrog kev cia khoom, xws li av noo, kub, qhov cua thiab lwm yam. Txhawm rau kom ntseeg tau tias qhov ua tau zoo ntawm cov nplaum tseem nyob hauv qhov tsis hloov pauv hauv lub sijhawm teev tseg, nws yog qhov yuav tsum tau ua tib zoo saib xyuas cov txheej txheem ntawm kev ua raws li cov nplaum nplaum. Ntau hom adhesives muaj ntau qhov chaw cia khoom vim lawv cov yam ntxwv sib txawv.
