Kev tsom xam ntawm lub ntsiab sib txawv ntawm cov khoom muaj acrylic resins

Cov Acrylic Resin yog ib qho tseem ceeb rau cov khoom lag luam lom neeg siv rau hauv cov txheej txheej, cov nplaum, kev hloov kho yas thiab lwm thaj teb. Vim nws cov huab cua zoo heev, tshuaj lom neeg ua tsis taus thiab ua yeeb yaj kiab ua yeeb yam, cov acrylic resin oceties txoj haujlwm tseem ceeb hauv txoj haujlwm tseem ceeb hauv kev lag luam. Txawm li cas los xij, sib txawv ntawm cov khoom acrylic muaj qhov sib txawv tseem ceeb hauv kev ua tau zoo thiab daim ntawv thov. Nkag siab cov kev sib txawv no tuaj yeem pab cov tuam txhab xaiv cov khoom uas zoo tshaj plaws lawv cov kev xav tau.

Ua ntej, los ntawm kev pom ntawm polymerization, khoom acrylic resins tuaj yeem faib ua ob pawg: thermoplastic resins thiab thermosetting resins. Thermoplastic Khoom acrylic resins soften thaum rhuab thiab rov ua dua tshiab tom qab txias. Cov txheej txheem no tau thim rov qab thiab haum rau qee lub sijhawm uas yuav tsum tau ua dua, xws li cov khoom yas thiab cov khoom siv yas. Thermogosetting cov khoom acrylic undergo cross cov kev sib tw hauv qab cov qauv cua nrog cov qauv siv hluav taws xob muaj ntau dua thiab muaj zog dua. Lawv feem ntau siv nyob rau hauv cov txheej txheem ua tau zoo thiab cov nplaum.

Qhov thib ob, kev ceeb toom hnyav thiab qib kev hla kev sib txuas yog qhov tseem ceeb cuam tshuam rau kev ua tau zoo ntawm cov khoom muaj acrylic. Resins nrog hnyav dua molecular hnyav feem ntau muaj cov kev siv tshuab zoo dua thiab cov kuab tshuaj kuj, tab sis kev ua kom txaus ntshai; Thaum cov resins nrog cov hnyav hnyav dua yog qhov yooj yim dua rau cov txheej txheem, tab sis tej zaum yuav muaj cov khoom siv lub cev ua tsis tau zoo me ntsis. Cov℃ntawm crosslinking txiav txim siab lub hardness, kub tsis kam thiab tshuaj tua tsis ntawm lub resin. Resins nrog cov qib siab crosslink

Tsis tas li ntawd, lub iav hloov ntsuas kub (tg) ntawm cov khoom muaj acrylic kuj tseem yog qhov ntsuas tseem ceeb. Resins nrog cov TG siab dua feem ntau nyuaj dua thiab haum rau qee zaus yuav tsum tau ua kom muaj zog, xws li kev hloov kho yas; Thaum cov resins nrog qis tg yog softer thiab haum rau elastic txheej los yog cov ntaub ntawv sib khi.

Hauv kev siv cov tswv yim, cov tuam txhab yuav tsum xaiv hom uas tsim nyog ntawm cov khoom muaj acrylic resin raws li cov kev xav tau. Piv txwv li, sab nraum zoov pleev xim feem ntau yuav tsum tau thermosetting cov resins nrog cov huab cua tiv thaiv cov yas yuav nyiam ua kom yooj yim ua. Nkag siab cov kev sib txawv no tuaj yeem pab ua kom cov txheej txheem ua kom zoo dua qub, txhim kho cov khoom lag luam zoo, thiab txhim kho kev ua lag luam kev sib tw.
