Kole ya UV ni nziza cyangwa si nziza?

Kole ya UV ni iki?

Ijambo "kole ya UV" muri rusange risobanura kole idafite igicucu, izwi kandi nka kole ishobora kuvurwa n'izuba cyangwa ultraviolet. Kole ya UV ikenera guhindurwa binyuze mu mucyo wa ultraviolet kandi ishobora gukoreshwa mu guhuza, gusiga irangi, gusiga irangi, n'ibindi bikorwa. Incamake ya "UV" isobanura imirasire ya Ultraviolet, ari yo mirasire ya electromagnetic itagaragara ifite uburebure bw'uburebure buri hagati ya 110 na 400nm. Ihame ry'uburyo kole ya UV idakozwe n'igicucu rikubiyemo kwinjiza urumuri rwa ultraviolet hakoreshejwe photoinitiators cyangwa photosensitizers mu bikoresho, biganisha ku gukora radicals cyangwa cations zikora zitangira polymerization no guhuza mu masegonda make.

 

Uburyo bwo gufata kole idafite igicucu: kole idafite igicucu yitwa kole ya ultraviolet, igomba kuba inyuze mu kurabagirana kwa ultraviolet kuri kole mu rwego rwo gupima, ni ukuvuga kole ikoresha fotosensitizing muri kole idafite igicucu kandi igakorana n'urumuri rwa ultraviolet izahuzwa na monomer, mu buryo bw'imitekerereze hatabayeho kurabagirana kw'urumuri rwa ultraviolet, kole idafite igicucu ntabwo izakira. Uko umuvuduko wo gupima UV urushaho gukomera, niko igihe cyo gupima muri rusange kigenda vuba hagati y'amasegonda 10-60. Kole idafite igicucu igomba kumurikirwa n'urumuri kugira ngo ivurwe, bityo kole idafite igicucu ikoreshwa mu gufatanya ishobora gusa guhuzwa n'ibintu bibiri bibonerana cyangwa kimwe muri byo kigomba kuba gifite icyerekezo, kugira ngo urumuri rwa ultraviolet rushobore kunyuramo no gushyuha kuri kole.

 

Ibiranga kole ya UV

1. Kurengera/kurengera ibidukikije

Nta bintu bihumanya ikirere bitagira VOC, nta mwanda uhumanya ikirere; ibintu bifatanye n'ibice bito bibujijwe cyangwa bibujijwe mu mategeko agenga ibidukikije; nta kintu kivangavanga, nta gutwika cyane

2. Byoroshye gukoresha kandi binoza imikorere myiza

Umuvuduko wo gukonjesha ni wihuta kandi ushobora kurangira mu masegonda make kugeza ku masegonda icumi, ibyo bikaba ingirakamaro ku mikorere ikora mu buryo bwikora kandi bikanoza umusaruro w'umurimo. Nyuma yo gukonjesha, ishobora gusuzumwa no gutwarwa, bigatuma igumana umwanya. Gukonjesha ku bushyuhe bw'icyumba bizigama ingufu, nko gukora kole ya 1g igabanya ubushyuhe ikoresha urumuri. Ingufu zisabwa ni 1% gusa by'ukole ikoresha amazi ijyanye nayo na 4% by'ukole ikoresha solvent. Ishobora gukoreshwa ku bikoresho bidakwiye gukonjesha ubushyuhe bwinshi. Ingufu zikoreshwa no gukonjesha ultraviolet zishobora kuzigama 90% ugereranije na resin ikoresha thermal curing. Ibikoresho byo gukonjesha biroroshye kandi bisaba amatara cyangwa imikandara yo kohereza gusa. Kuzigama umwanya; sisitemu y'igice kimwe, nta kuvanga bikenewe, byoroshye gukoresha.

3. Guhuza ibintu

Ibikoresho bishobora kwifashishwa mu bushyuhe, ibintu bishongesha umwuka n'ubushuhe.

Genzura uburyo bwo gukonjesha, igihe cyo gutegereza gishobora guhindurwa, urugero rwo gukonjesha rushobora guhindurwa. Kole ishobora gukoreshwa kenshi mu gukonjesha inshuro nyinshi. Itara rya UV rishobora gushyirwa byoroshye mu murongo usanzwe ukoreshwa nta mpinduka zikomeye.

4. Uburyo bwinshi bwo gukoresha n'ingaruka nziza zo guhuza

Kole ya UV ifite akamaro kanini kandi ifite ingaruka nziza zo guhuza hagati ya pulasitiki n'ibikoresho bitandukanye. Ifite imbaraga nyinshi zo guhuza kandi ishobora gusenya umubiri wa pulasitiki idakoresheje ibizamini byo gusenya. Kole ya UV ishobora gushyirwa mu masegonda make, ikagera ku bushyuhe bwinshi mu munota umwe;

Irabonerana neza nyuma yo gushya, kandi ibicuruzwa ntibizahinduka umuhondo cyangwa umweru igihe kirekire. Ugereranyije n'uburyo busanzwe bwo gufatanya ibintu mu buryo bwihuse, ifite ibyiza byo kudakoresha ibizamini byo kurengera ibidukikije, nta kwera, koroha neza, nibindi. Ifite ubushyuhe buke, ubushyuhe bwinshi n'ubukonje bwinshi.
