Iriburiro: Uburyo bwo guhererekanya ubushyuhe, inzira isanzwe muburyo bwo kuvura ibikoresho byo kwisiga byo kwisiga, kuko byoroshye gucapa, kandi ibara nibishusho birashobora gutegurwa. Ninzira abafite ibicuruzwa bakunda. Ibikurikira byahinduwe naURUPAPURO RB.Reka dusangire ibibazo byubuziranenge hamwe nibisubizo hamwe ningaruka ziterwa no guhererekanya amashyuza, kugirango ubone ibisobanuro byatanzwe muri Youpin:
Kwimura ubushyuhe
Uburyo bwo guhererekanya amashyuza bivuga impapuro zoherejwe zometseho pigment cyangwa amarangi nkibikoresho, binyuze mu gushyushya, kotsa igitutu nubundi buryo bwo kwimura igishushanyo mbonera cya wino ku buryo bwo gucapa. Ihame ryibanze ryo kwimura amashyuza ni uguhuza byimazeyo na wino ikozwe hamwe na substrate. Binyuze mu gushyushya no gukanda igitutu cyumutwe wanditse hamwe na silinderi yerekana, wino yo hagati izashonga hanyuma yimurwe muri substrate kugirango ubone ibyifuzo Byacapwe.
01Ingaruka ziterwa no guhererekanya ubushyuhe
1) Umutwe wo gucapa
Umutwe wanditseho ubushyuhe bugizwe ahanini nubuso bufatika bwo gukingira firime, munsi yo gufunga firime yo gukingira no gushyushya ibintu. Ibikoresho byo gushyushya ni ecran ya silike. Hifashishijwe ubushyuhe butangwa na voltage pulse, uduce duto duto twa wino igice cyibishushanyo bishushanyijeho kandi bishonga kugirango barangize ihererekanyabubasha.
Icapiro ryihuta ryumuriro biterwa nigihe gikenewe kuri buri murongo wibishushanyo ninyandiko. Kubwibyo, umutwe woherejwe nubushyuhe hamwe nimpapuro zoherejwe bigomba kugira ihererekanyabubasha ryiza, kugirango ubushyuhe butangwa nibintu bishyushya bishobora guhita byanyura murwego rwo gukingira, impapuro zoherejwe hamwe nu cyuho hanyuma amaherezo bikagera hejuru yubutaka kugirango harebwe ko wino ifite igihe gihagije cyo kwimura.
2) Ink
Ibigize ihererekanyabubasha rya wino muri rusange ni ibice bitatu: pigment (pigment cyangwa irangi), ibishashara namavuta, muribwo ibishashara aribintu nyamukuru bigize wino yohereza amashyuza. Ibanze shingiro rya rusange yohereza amashyuza irashobora kwerekanwa kumeza 1.
Imbonerahamwe 2 nicyitegererezo cya ecran icapura ubushyuhe bwo kohereza wino. N-mikorerexymethyl polyamide ishonga muri alcool ya benzyl, toluene, etanol nindi mashanyarazi, pigment irwanya ubushyuhe na bentonite yongewemo kugirango ikangurwe, hanyuma igashyirwa muri wino yo gucapa. Irangi ryacapwe kubitwara (nkimpapuro zoherejwe nubushyuhe) ukoresheje uburyo bwo gucapa ecran, hanyuma umwenda ugakanda cyane hanyuma ukimurwa.
Iyo icapiro, ubwiza bwa wino zitandukanye bufitanye isano nubushyuhe bwo gushyuha, kandi ubushyuhe bwo gushyuha hamwe nubwiza bwa wino bigomba kugenzurwa cyane. Imyitozo yerekanye ko iyo ubushyuhe bwo gushyuha ari 60 ～ 100 ℃, iyo wino ishonga, agaciro ka viscosity ya wino gahagaze kuri 0,6 Pa · s, nibyiza cyane. Mubisanzwe nukuvuga, uko wino yegereye iyi leta, nibyiza kwimurwa.
Mu myaka yashize, hamwe nogutezimbere tekinoroji yumukororombya wa shanghai, ubushyuhe bwo kubika ibicuruzwa byacapwe bwiyongereye kuva kuri 45 ℃ kugeza kuri 60 ℃, bwaguye cyane murwego rwo kohereza amashyuza. Mubyongeyeho, gukoresha pigment ibonerana cyangwa irangi risobanutse bitanga ingaruka nziza kumabara.
3) Kohereza itangazamakuru
Substrates zitandukanye zifite ibintu bitandukanye, mugihe rero uhisemo kwimura impapuro, ugomba kwitondera ibintu bikurikira byerekana substrate.
Performance Imikorere yumubiri
Ibintu bifatika byimpapuro zoherejwe bigaragara mu mbonerahamwe ya 3.
Ibimaze kuvugwa haruguru nibintu bifatika byimpapuro eshatu zoherejwe nubushyuhe. Ibice bitatu bikurikira birashobora gusuzumwa muguhitamo:
Ubunini bwa substrate ntibugomba kuba burenze 20 mm;
Substrate igomba kuba ifite urwego rwo hejuru rworoshye kugirango yizere ko ihererekanyabubasha rya wino;
Substrate igomba kugira imbaraga zihagije kugirango irebe ko itazatanyurwa mugihe cyo kohereza impapuro no gucapa.
PropertiesImiterere yimiti
Gufata neza ndetse na wino ni ibintu bibiri byingenzi byerekana imiterere yimiti yimpapuro zoherejwe. Mu musaruro, imiterere yimiti yimpapuro zigira ingaruka muburyo bwiza bwo gucapa. Niba impapuro zoherejwe zidashobora gutuma wino ifata neza, cyangwa ingano ya wino itamenyerewe mubikorwa, bizatera imyanda yo gucapa. Uburyo bwiza bwo gucapa hamwe nicapiro ryiza bigomba gushingira ku gufata neza imiterere yimiti yimpapuro.
PerformanceImikorere myiza yubushyuhe
Kubera ko inzira yo kwimura igerwaho nubushyuhe bwo hejuru bivuze, ibikoresho byimpapuro zoherejwe bigomba kuba bishobora guhangana ningaruka zubushyuhe bwo kwimura no kugumana ibintu bidahindutse. Muri rusange, niba imikorere yubushyuhe bwa substrate yimpapuro zihererekanyabubasha ari nziza birashobora kugaragazwa nimpamvu zikurikira:
Hasi yubushyuhe bwubushyuhe bwa substrate idashobora guhangana nubushyuhe, ubunini buke, niko guhererekanya ubushyuhe, nuburyo bwiza bwo gukora ubushyuhe;
Ubworoherane Ubuso bworoshye bwa substrate, niko bigabanya ubushyuhe nubushyuhe bwiza;
Ubushyuhe bwumuriro wihanganira ubushyuhe bwumutwe muri rusange hafi ya 300 ℃, kandi substrate igomba kuba ishobora kwemeza ko imikorere nyamukuru idahinduka kuri ubu bushyuhe.
4) Substrate
Substrates hamwe nubuso buto bugaragara bifite ireme ryiza ryanditse, nikintu cyingenzi kiranga ihererekanyabubasha. Kuberako ubuso bubi bwa substrate bwerekana ko substrate ifite ingufu nini zo hejuru, wino kumpapuro zoherejwe irashobora kwimurwa kuriba, kandi urwego rwiza nijwi bishobora kuboneka; ariko bikabije bizagira ingaruka kumiterere ya wino Ubusanzwe kwimura ntabwo bifasha kumenya uburyo bwo gucapa.
