Impamvu no kuvura nabi gufatira kwa UV gukiza amarangi yo gutera amarangi

UV ikiza irangi ni ubwoko bwicyatsi kibisi cyo kurengera ibidukikije, gifite ibiranga gukorera mu mucyo mwinshi, gukomera cyane no kurwanya ibishushanyo.Ikoreshwa cyane mubikorwa bya plastike cyangwa ibyuma bya substrate.Ikintu kidasanzwe kigira ingaruka ku bwiza bwo gutwikira no gutanga umusaruro mu gutera UV ni irangi rigwa, ni ukuvuga ko guhuza hagati ya UV ikiza amarangi na substrate ari bibi.Noneho tuzasesengura ibitera nigisubizo cyo gufatana bigoye duhereye kubintu bibiri byo gusiga irangi UV no gutera substrate.

Impamvu zituma UV ikiza irangi bigoye kubahiriza substrate:

Uhereye ku isesengura rya UV ikiza irangi, ingaruka za UV zifata kuri substrate ni ntege nke muburyo bwo kwinjira.Urebye imikorere nyuma yo gukira, viscosity ya sisitemu ntoya ya resin sisitemu yiyongera kandi amazi agabanuka, bityo guhanagura no kwinjira muri substrate ntibihagije.Byongeye kandi, kugabanuka kwijwi rya UV mugihe cyo gukira nigihe cyo kwitwara byihuse nibintu bibiri.Iyambere izatera itandukaniro ryimiterere hagati yo gutwikira hamwe na substrate, bityo bigatera impagarara hagati yo gutwikira;Iyanyuma iterwa nigikorwa cyihuse, kizatera kudahuza imiterere ya sisitemu ya UV.

Urebye kuri substrate yo gusiga irangi UV, ikintu cya mbere ugomba gusobanukirwa ninshingano yo gufatira hamwe.Imbaraga zo kubaho kwazo zerekana niba irangi na substrate bishobora kubona gufatana kugirango bibe igifuniko gikomeye.Hano rero tugomba kuvuga ingaruka ziterwa na substrate polarite, kristu, imbaraga zo hejuru hamwe no koroha kubutaka bwubutaka.Hafi ya polarite cyangwa polarite, nka plastike ya PP, bigoye gusiga amavuta, kristu nyinshi hamwe nimbaraga zo hasi, nka PA nylon substrate, mugihe ubworoherane bugaragara cyane mubyuma bidafite ingese.Kubwibyo, imiterere ya molekulire nimiterere ya substrate nayo igira ingaruka zikomeye kuri adhesion.Kubwibyo, mugihe irangi rya UV rishobora guhinduka, urufunguzo rwo gukemura ikibazo cyo gufatana nabi kw irangi rya UV nugutezimbere guhuza hagati ya substrate n irangi rya UV.

Uburyo bwo kongera imbaraga hagati ya UV irangi hamwe na substrate:

Muburyo bwo gukemura ifatizo rya UV ikiza irangi yatewe hejuru ya plastiki cyangwa ibyuma, urwego rwirangi ruhagaze rushyirwa hejuru yubutaka bwa substrate Sichuan imiti ivura imiti nigisubizo cyiza cyo kongera ubwuzuzanye hagati ya substrate na UV. .Ubwa mbere, imiti ivura irashobora gufata neza substrate.Icya kabiri, umukozi wo kuvura arimo hydrogène ihujwe na radicals yubusa hamwe nitsinda rya polar nka hydroxyl ya substrate, bigatuma firime irushaho gukomera.Muri icyo gihe, imiti ivura hamwe n irangi irashobora kandi gukora imiti ihuza imiti, izahuza ubuso bwa substrate hamwe na UV, kandi bikarushaho guteza imbere gushiraho urwego rwo hejuru rwo gufatana hagati y irangi rya UV na substrate.
