Kumenyekanisha bivuze ko mugihe cyo kurasa k'umucyo ultraviolet, fotoinitiator ikuramo ingufu z'umucyo ikangirika muri radicals yubuntu, hanyuma radicals yubuntu noneho igatangiza monomer ya Photopolymerisation kugirango ikore polymerisation hamwe no guhuza ibitekerezo. Imurikagurisha muri rusange rikorwa mumashini yikora impande zombi. Noneho imashini imurika irashobora kugabanywamo ubukonje bwumuyaga hamwe nogukonjesha amazi ukurikije uburyo bwo gukonjesha isoko yumucyo.

Ibintu bigira ingaruka kumashusho meza

Usibye imikorere yumufotozi wamafirime, ibintu bigira ingaruka kumiterere yerekana amashusho ni uguhitamo amasoko yumucyo, kugenzura igihe cyo kumurika (umubare wimurikabikorwa), hamwe nubwiza bwibyapa bifotora.

1) Guhitamo isoko yumucyo

Ubwoko bwa firime iyo ari yo yose ifite uburyo bwihariye bwo gukurura umurongo, kandi ubwoko ubwo aribwo bwose bw'umucyo nabwo bufite ibyuka byangiza. Niba impanvu nyamukuru yo kwinjiza ibintu byubwoko runaka bwa firime irashobora guhuzagurika cyangwa ahanini igahuzagurika hamwe n’imyuka ihumanya ikirere y’isoko ry’umucyo runaka, byombi bihuye neza kandi ingaruka zo kwerekana ni nziza.

Kwikuramo kwerekanwa kwa firime yumye murugo byerekana ko akarere kinjiramo ni 310-440 nm (nanometero). Uhereye ku gukwirakwiza ingufu z'amashanyarazi zituruka ku masoko menshi y’umucyo, urashobora kubona ko itara ryatoraguwe, itara ryinshi rya mercure ya mercure, hamwe n’itara rya galiyumu rifite imbaraga nini ugereranije n’imirasire y’umurambararo wa 310-440nm, akaba ari isoko nziza yumucyo kuri firime. Amatara ya Xenon ntabwo akwiriyekwerekanwaya firime yumye.

Nyuma yumucyo isoko yumucyo yatoranijwe, isoko yumucyo nimbaraga nyinshi nayo igomba kwitabwaho. Kubera urumuri rwinshi rwinshi, rukemurwa cyane, nigihe gito cyo kwerekana, urwego rwo guhindura ubushyuhe bwa plaque yifoto nayo ni nto. Mubyongeyeho, gushushanya amatara nabyo ni ngombwa cyane. Birakenewe kugerageza gukora ibyabaye byoroheje kandi bigereranywa, kugirango wirinde cyangwa ugabanye ingaruka mbi nyuma yo kugaragara.

2) Kugenzura igihe cyo kwerekana (amafaranga yo kwerekana)

Mugihe cyo kwerekana, fotopolymerisation ya firime ntabwo "ishusho imwe" cyangwa "imwe-imwe", ariko muri rusange inyura mubyiciro bitatu.

Bitewe no guhagarika ogisijeni cyangwa indi myanda yangiza muri membrane, harasabwa inzira yo kwinjiza, aho radicals yubuntu iterwa no kubora kwa nyirarureshwa ikoreshwa na ogisijeni n’umwanda, kandi polymerisation ya monomer ni nto. Ariko, iyo igihe cyo kwinjiza kirangiye, Photopolymerisation ya monomer igenda yihuta, kandi ubwiza bwa firime bwiyongera vuba, bwegera urwego rwimpinduka zitunguranye. Nicyiciro cyo gukoresha byihuse byamafoto ya monomer, kandi iki cyiciro kibara ubwinshi bwigaragaza mugihe cyo kwerekana. Igipimo cyigihe ni gito cyane. Iyo ibyinshi bifotora monomer bimaze gukoreshwa, byinjira muri monomer depletion zone, kandi reaction ya Photopolymerisation yarangiye muriki gihe.

Kugenzura neza igihe cyo kwerekana ni ikintu cyingenzi cyane kugirango ubone firime nziza yumye irwanya amashusho. Iyo imurikagurisha ridahagije, bitewe na polymerisime ituzuye ya ba monomers, mugihe cyiterambere, firime yifata irabyimba igahinduka yoroshye, imirongo ntisobanutse neza, ibara ryijimye, ndetse rikaba ryarasuzuguwe, kandi firime ikarishye mugihe cyambere -gutegura cyangwa amashanyarazi. , seepage, cyangwa no kugwa. Iyo guhura ari hejuru cyane, bizatera ibibazo nkikibazo cyo kwiteza imbere, firime yoroheje, hamwe na kole isigaye. Ikirenzeho cyane nuko guhura nabi bizatera gutandukana kwubugari bwumurongo. Kurenza urugero bizagabanya umurongo wo gushushanya no gukora imirongo yo gucapa no gutobora cyane. Ibinyuranye, imikoreshereze idahagije izatuma imirongo yerekana ishusho iba yoroheje. Ntibisanzwe kugirango imirongo yanditswemo ibe yoroheje.
