Ibiranga no gucapa ubuhanga bushingiye ku mazi kumpapuroagasanduku ka shokora
Indogobe ishingiye ku mazi nigicuruzwa cyangiza ibidukikije cyatsinzwe cyane mumyaka yashizeAgasanduku. Ni irihe tandukaniro riri hagati yinyoni zishingiye kumazi na wino rusange, kandi ni izihe ngingo zikeneye kwitabwaho? Hano, Meibang izagusobanurira birambuye kuri wewe.
Inoti ishingiye ku mazi yakoreshejwe mu icapiro ry'impapuro z'imigano igihe kirekire mu mahanga no ku myaka irenga 20 murugo. Gucapa impapuro zahujwe byateje imbere gucapa (gucapa ubutabazi), Gucapa bya Offset (Gucapa bya Offset) na Shote Plate Amazi Yashable Icapiro rishingiye ku icuranwa rishingiye ku gicapo. Ihuriro ryubutabazi rishingiye ku mazi naryo ryateye imbere muri Rosin-Maleic Acide yahinduwe resin urukurikirane rwa Acryc. Isahani yo gucapa nayo itandukanya na rubber kugirango isize. Imashini icapiro nayo yateye imbere buhoro buhoro imashini imwe cyangwa amabara abiri hamwe na roller nini kumabara atatu cyangwa amabara ane ya flexo.
Ibigize kandi biranga inka ishingiye ku mazi ni kimwe no kurwara rusange. Inkongo zishingiye ku mazi zigizwe nubusanzwe, bihuza, bihuza, abafasha nibindi bice. Amabara nibara ryinyoni ishingiye ku mazi, itanga ink ibara ryihariye. Kugirango dushobore gutekereza neza mu icapiro rya Flexografiya, muri rusange ikoresha muri make hamwe ningurube zifite imiti myiza yimiti n'imbaraga zo hejuru; Binder igizwe n'amazi, resin, amine ibice nibindi bilime. Resin nigice cyingenzi mubice bishingiye kumazi. Ibisubizo bya Acrylc Resin mubisanzwe bikoreshwa. Ibigize Binder bigira ingaruka muburyo bwo gupfumuzi, umuvuduko wumisha, imikorere yo kurwanya, nibindi. Amine ibice bikomeza ahanini agaciro ka alkaline ya alkaline yindege ishingiye kumazi, kugirango resin ya acrylic ishobore gutanga ingaruka nziza. Amazi cyangwa Ibindi bicuruzwa byamazi ahanini bishonga cyane, hindura vicosity no kumisha yinjira muri wino; Abafasha bafasha ahanini barimo: Defomemero, Blocker, Stabilizer, Diluennt, nibindi.
Nkuko wino ishingiye ku mazi ari isabune, biroroshye kubyara ibituba gukoreshwa, amavuta ya silicone agomba kongerwaho nka defoamer yo kubuza no gukuraho ibituba, no kunoza imikorere yo kwanduza wino. Abanditsi bakoreshwa mu kubuza umuvuduko wumye wamazi, wirinde wino kuva kumitsi ya Anilox no kugabanya paste. Ikibaho kirashobora guhindura agaciro ka PH yino, kandi gishobora gukoreshwa nka diluent kugirango ugabanye vino. Diluntint ikoreshwa mukugabanya ibara ryino-ishingiye ku mazi, kandi irashobora gukoreshwa nkigikorwa cyiza cyo kunoza umucyo wino. Byongeye kandi, ibishashara bimwe bigomba kongerwaho wino ishingiye ku mazi kugirango yongere ingwate.
Inoki ishingiye ku mazi irashobora kuvangwa n'amazi mbere yo gukama. Iroki imaze kyuma, ntibizongera gushonga mumazi na wino. Kubwibyo, wino ishingiye kumazi igomba kuba yaratewe imbere mbere yo gukoreshwa kugirango ukomeze umwambaro wa wino. Iyo wongeyeho wino, niba wino isigaye muri tank ya wino irimo umwanda, igomba kubanza kuyungurura mbere, hanyuma ikoreshwa hamwe na wino nshya. Iyo icapiro, ntukemere ko wino yumye kumuzingo wa anilox kugirango wirinde guhagarika umwobo wa Inkingi. Guhagarika kwanduza cyane wino itera gucapa. Mugihe cyo gucapa, Flexplate igomba guhora igwa na wino kugirango irinde guhagarika inyandiko ku isahani yo gucapa nyuma yindege yumye. Byongeye kandi, harasanga iyo viscogitity yinyoni ishingiye kumazi ari hejuru gato, ntabwo ikwiye yongera amazi muburyo bwirinda gushikama ryikirere. Urashobora kongeramo umubare ukwiye wo kugihindura.
