Cov txheej txheem pleev xim rau cov txheej txheem pleev xim ntoo uas kho los ntawm UV

Lub hom phiaj ntawm kev tshawb fawb tshiab yog los tshuaj xyuas qhov cuam tshuam ntawm cov khoom sib xyaw ua ke thiab qhov tuab ntawm cov xim pleev rau ntawm tus cwj pwm kho tshuab ntawm cov txheej txheem tiav ntoo ntau txheej uas UV-kho tau.

Qhov ruaj khov thiab zoo nkauj ntawm cov ntoo hauv pem teb yog los ntawm cov yam ntxwv ntawm cov txheej uas siv rau ntawm nws qhov chaw. Vim lawv qhov ceev ceev kho, qhov ceev ntawm kev sib txuas thiab kev ruaj khov siab, cov txheej UV-curable feem ntau nyiam rau cov chaw tiaj tus xws li cov ntoo hauv pem teb, cov rooj thiab cov qhov rooj. Hauv cov ntoo hauv pem teb, ntau hom kev puas tsuaj ntawm cov txheej txheej tuaj yeem ua rau kev pom ntawm tag nrho cov khoom puas tsuaj. Hauv cov haujlwm tam sim no, cov qauv UV-curable nrog ntau yam monomer-oligomer khub tau npaj thiab siv ua lub hauv paus hauv cov txheej txheem ntoo tiav ntau txheej. Thaum lub tsho sab saud yog tsim los ua kom feem ntau ntawm cov khoom siv, kev ntxhov siab elastic thiab yas tuaj yeem ncav cuag cov khaubncaws sab nraud povtseg tob dua.

Thaum lub sijhawm kawm, cov khoom siv lub cev xws li qhov nruab nrab theoretical segment ntev, iav hloov kub thiab crosslinking density, ntawm cov yeeb yaj kiab standalone ntawm ntau yam monomer-oligomer khub niam txiv tau raug tshawb xyuas. Tom qab ntawd, indentation thiab khawb tsis kam kev ntsuam xyuas tau ua tiav kom nkag siab txog lub luag haujlwm ntawm cov basecoats hauv tag nrho cov lus teb mechanical ntawm cov multilayered coatings. Lub thickness ntawm basecoat thov tau pom tias muaj kev cuam tshuam loj rau cov mechanical tsis kam ntawm lub kaw lus tiav. Tsis muaj kev sib raug zoo ncaj qha tau tsim ntawm lub basecoat ua cov yeeb yaj kiab standalone thiab hauv cov multilayered coatings, xav txog qhov nyuaj ntawm cov kab ke zoo li no ntau tus cwj pwm tau pom. Ib lub kaw lus tiav uas tuaj yeem txhawb nqa tag nrho cov kev tiv thaiv khawb zoo thiab zoo indentation modulus tau txais rau ib qho formulation qhia txog kev sib npaug ntawm lub network ceev thiab elasticity.
