Imikoreshereze
Photoinitiator TPO ni photoinitiator ifite ubushobozi bwo gukurura ibintu mu buryo bwa free radical (1) kandi ifata mu rugero rurerure rw'uburebure bw'umuraba. Bitewe n'urwego rwayo runini rwo gukurura ibintu, urwego rwayo rwo gukurura ibintu ni 350-400nm kandi ifata buri gihe kugeza kuri 420nm. Urwego rwayo rwo gukurura ibintu rurerure kurusha urw'ibikoresho bisanzwe. Nyuma yo kumurikirwa, radical ebyiri zisanzwe, benzoyl na phosphoryl, zishobora gukorwa, byombi bishobora gutangiza polymerization. Kubwibyo, umuvuduko wo gukurura ibintu mu buryo bwa photocuring ni wo wihuta. Ifite kandi ingaruka zo gukurura ibintu mu buryo bwa photobleach kandi ikwiriye gukurura ibintu mu buryo bunini kandi iranga irangi ritari umuhondo. Ifite imihindagurikire mike kandi ikwiriye sisitemu zishingiye ku mazi.
Ikoreshwa cyane mu buryo bw'umweru kandi ishobora gushyirwa ku bitambaro bivurwa n'imirasire ya UV, inyito zo gucapa, kole zivurwa n'imirasire ya UV, ibitambaro bya fibre optique, photoresists, plaque zo gucapa za photopolymer, resins za stereolithography, ibikoresho bivanze, ibikoresho byo kuzuza amenyo, nibindi.
Nk'igikoresho cyo gushushanya, gikoreshwa cyane cyane mu ibara rya ecran printing, ibara rya lithographic printing, ibara rya flexographic printing, n'ibara ry'ibiti. TPO ishobora kuvurwa burundu ku buso bw'umweru cyangwa bufite ibara rya titanium dioxide. Ikoreshwa cyane mu ibara ritandukanye. Bitewe n'ubushobozi bwayo bwiza bwo kwinjiza, ikwiriye cyane cyane ibara rya ecran printing, ibara rya lithographic, ibara rya flexographic printing, n'ibara ry'ibiti. Ibara ntirihinduka umuhondo, rifite ingaruka nke nyuma ya polymerization, kandi nta bisigazwa risiga. Rishobora kandi gukoreshwa mu ibara ribonerana, cyane cyane rikwiriye ibicuruzwa bifite impumuro nke. Iyo rikoreshejwe ryonyine muri polyester idafunze irimo sisitemu za styrene, rifite ubushobozi bwo gutangira cyane. Kuri sisitemu za acrylate, cyane cyane sisitemu z'amabara, akenshi rikenera gukoreshwa hamwe na amine cyangwa acrylamide. Muri icyo gihe, rivangwa n'izindi fotoinitiators kugira ngo rigere ku buziranenge bwuzuye bwa sisitemu. Rikwiriye cyane cyane mu gukosora sisitemu z'umuhondo muto, umweru n'ibice binini bya filime. Iyo icyuma gitera imbaraga (TPO) gikoreshejwe hamwe na MOB 240 cyangwa CBP 393, ubushobozi bwo gukaraba bushobora kunozwa. Ni cyo kintu cyiza cyane gikoreshwa mu gukaraba lisansi, kandi gikoreshwa no mu gukaraba lisansi mu bijyanye n'imiti myiza.
Gupakira no Kohereza
20KG/Ingoma cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
