Taw qhia rau UV Pem Teb Txheej: Tsim kom muaj kev ruaj khov thiab ib puag ncig zoo tiv thaiv Pem Teb Kev daws teeb meem

UV txheej txheej yog siab -molecular functional txheej txheej txheem uas siv ultraviolet lub teeb ua lub zog kho. Tsim tshwj xeeb rau hauv pem teb kev tiv thaiv thiab kho kom zoo nkauj, nws tau siv dav hauv xyoo tas los no hauv tsev, chaw lag luam, pej xeem cov chaw, thiab cov nroj tsuag muaj kev lag luam. Nrog nws qhov zoo ntawm kev kho sai, kho tau zoo, ib puag ncig tus phooj ywg qis emissions, thiab siab durability, nws tau dhau los ua cov khoom tseem ceeb rau kev txhim kho cov hnav tsis kam, stain tsis kam, huab cua tsis kam, thiab cov txiaj ntsig zoo ntawm kev ua si hauv pem teb, kev loj hlob zoo ntawm cov plag tsev. thiab kev coj ua ntsuab.

Cov txheej txheem kho ntawm UV txheej hauv pem teb yog ua raws li cov dawb radical lossis cationic photopolymerization cov tshuaj tiv thaiv pib los ntawm lub teeb ultraviolet. Tom qab daim ntawv thov, cov photosensitive resin (xws li epoxy acrylate, polyurethane acrylate, thiab polyester acrylate) thiab reactive diluent nyob rau hauv lub txheej ua tiav tus ntoo khaub lig- txuas cov tshuaj tiv thaiv nyob rau hauv vib nas this mus rau kaum vib nas this nyob rau hauv qhov kev txiav txim ntawm ib tug photoinitiator, hloov los ntawm cov kua rau ib tug khoom lub xeev. Qhov thib ob no - theem curing yam ntxwv tshem tawm qhov siab - qhov kub thiab txias uas yuav tsum tau ua los ntawm cov txheej txheem thermal curing, txo qis kev siv hluav taws xob thiab tsis txhob thermal deformation thiab kev ua haujlwm puas rau ntoo, composite, los yog PVC pem teb substrates, ua rau nws tshwj xeeb tshaj yog haum rau txheej tshav kub-sensitive substrates. Nyob rau hauv cov nqe lus ntawm cov khoom muaj pes tsawg leeg, UV txheej hauv pem teb feem ntau muaj oligomers, reactive diluents, photoinitiators, thiab functional additives. Oligomers txiav txim siab cov txheej txheem hardness, yooj, thiab tshuaj tiv thaiv; reactive diluents kho qhov system viscosity thiab curing ceev; photoinitiators nqus ultraviolet lub teeb los tsim cov chaw ua haujlwm polymerization; thiab additives impart functions xws li leveling, defoaming, adhesion nce, khawb kuj, yellowing kuj, plam tsis kam, los yog antibacterial zog. Los ntawm kev tsim qauv, ntau yam teebmeem tuaj yeem ua tiav, suav nrog siab gloss, matte, plam-resistant, ntiv tes-resistant, stain{11}}resistant thiab yooj yim-rau- huv, thiab UV- thaiv, ua tau raws li qhov xav tau ntawm qhov chaw sib txawv.

Qhov zoo ntawm UV txheej txheej yog feem ntau cuam tshuam hauv kev tsim khoom. Lawv txoj kev kho sai sai ua rau cov kab ntau lawm ceev, ua kom muaj kev ua haujlwm tas mus li thiab loj -, tshwj xeeb tshaj yog tsim rau thaj chaw uas yuav tsum tau muaj peev xwm thiab sib xws, xws li cov rooj tog hauv tsev, kev lag luam hauv pem teb, thiab kho kom zoo nkauj prefabricated. Qhov thib ob, lawv muab cov txiaj ntsig zoo ib puag ncig. Cov txheej txheem kho yuav luag tsis muaj cov organic sib txuas (VOCs), txo cov pa phem thiab kev pheej hmoo rau kev noj qab haus huv, thiab ua raws li kev tswj hwm ib puag ncig nruj dua ob qho tib si hauv tebchaws thiab thoob ntiaj teb. Thirdly, lawv muab kev ua tau zoo tsim qauv yooj yim. Customized solutions for hardness, wear resistance, water resistance, chemical corrosion resistance, and decorative properties can be developed based on the substrate type (cov khoom ntoo, plywood, xyoob, PVC, SPC, thiab lwm yam) thiab kev siv ib puag ncig (siab-tig pej xeem cheeb tsam, chav ua noj, chaw soj nstuam, sab nraum zoov terraces, thiab lwm yam). Fourth, the thin and dense coating maintains the natural texture of the substrate while providing excellent scratch resistance, shoe print resistance, easy cleaning, and long-lasting newness.

Daim ntawv thov txheej txheem feem ntau suav nrog substrate deg pretreatment (tu, sanding, filling gaps, thiab siv lub sealing primer), txheej (kho, txau, los yog cov menyuam txheej), infrared preheating (nyob rau hauv ib co tshuab, siv rau leveling thiab cua npuas tshem tawm), thiab UV curing. Kev kho lub zog, kev siv lub teeb, thiab lub sijhawm irradiation yuav tsum tau tswj xyuas kom meej kom ua tiav cov ntoo khaub lig- txuas thiab ua tiav qhov kev ua tau zoo. Rau thaj chaw loj lossis cov plag tsev tsis zoo, ntau qhov chaw teeb pom kev lossis ntau -lub kaum sab xis irradiation tuaj yeem siv kom tsis txhob muaj kev kho tsis txaus hauv cov chaw ntxoov ntxoo, ua rau muaj qhov tsis xws luag hauv cheeb tsam.

Txawm hais tias nws cov txiaj ntsig tseem ceeb, kev sib raug zoo ntawm cov substrate thiab kev ruaj ntseg ntawm cov txheej txheem tseem yog ib qho tseem ceeb rau kev txiav txim siab rau UV txheej hauv pem teb hauv kev siv tswv yim. Qee cov substrates tuaj yeem daj nyob rau hauv kev cuam tshuam ntawm lub teeb ultraviolet lossis photoinitiator decomposition khoom, yuav tsum tau xaiv cov khoom siv tiv thaiv - daj thiab lub teeb stabilizers. Kev kho tsis txaus lossis ntau dhau yuav cuam tshuam rau adhesion thiab durability; optimum parameters yuav tsum tau txiav txim los ntawm cov txheej txheem validation. Tsis tas li ntawd, qhov sib txawv ntawm kev siv ib puag ncig muaj ntau yam kev xav tau rau kev tiv thaiv- plam, dej- tiv taus, thiab tshuaj lom neeg- cov khoom tiv taus, xav tau kev ua kom zoo dua thaum lub sijhawm tsim thiab txheej txheem.

Zuag qhia tag nrho, UV txheej hauv pem teb, nrog rau lawv sai sai, ib puag ncig tus phooj ywg qis - emission, adjustable kev ua tau zoo, thiab dav siv tau, muab kev tiv thaiv zoo thiab ruaj khov thiab kho kom zoo nkauj rau hauv pem teb, ua kom pom qhov muaj txiaj ntsig zoo hauv kev txhim kho hauv pem teb, txuas ntxiv txij nkawm, thiab txhawb kev txhim kho ntsuab ntawm kev lag luam txheej.
