Ilebula Lensimbi Engagqwali Eqoshwe Ikhwalithi Ephezulu Engokwezifiso Egcwaliswe Ngombala

Ilebula Yensimbi Engagqwali Eqoshwe Ngokwezifiso umaka osetshenziswa kakhulu ongadlala indima ebalulekile ezindaweni ezahlukahlukene, njengamalebula omkhiqizo. Ikakhulukazi kwezinye izindawo ezinokhahlo, amalebula ensimbi engagqwali anezakhiwo ezinhle kakhulu njengokuqina, ukumelana nokugqwala, nokumelana nokugqokwa, amalebula ensimbi engagqwali ngokuvamile asetshenziswa embonini, emishinini, ezindiza, ezimotweni nakwezinye izinkambu ukumaka amagama emishini, izaziso nezixwayiso, kanye imiyalelo yomshini.Ezimbonini ezifana namandla kagesi, imboni yamakhemikhali, amalahle, nensimbi, izimpawu ezingezona ezensimbi zisetshenziswa kakhulu.

Inqubo yokukhiqiza amalebula ensimbi engagqwali ihlukaniswe ngezinyathelo ezintathu: etching, stippling and polishing.

(1): Ukuhleka. I-Etching iwukuqopha izinhlamvu ezidingekayo noma amaphethini ebusweni bensimbi engagqwali ngokusebenzisa i-etchant. Le nqubo idinga ukusetshenziswa kwe-negative plate making, ukuchayeka ngokuphambene, ukuthuthukiswa, ukugeza amapuleti nezinye izinqubo zokwenza amapuleti. Ngokuvamile, lapho wenza amalebula ensimbi engagqwali, kuyadingeka ukuthi udlulise umbhalo namaphethini, bese umboza indawo engacijile ngelembozo elincanyana le-chemical fiber elilingana nephepha elibonisa ngale, bese usebenzisa isixazululo esiqoshiwe esinezindonga ezincane esigqwalile khipha izingxenye ezingewona amashadi. Yenza ingxenye yeshadi iphumele ngaphandle, futhi ishadi nombhalo kube nesilinganiso somumo ocolekileyo.

(2): upende wamabala. Upende obala uwukubeka upende womkhiqizo wensimbi ongacijile oqediwe kwamanye amaphuzu eshadini noma umbhalo ukuze uzuze umuzwa ongcono wokubukwayo. Imibala esetshenziswa kulobu buciko kumele ibe yimibalabala egxile kakhulu ezinkondlo, futhi okuqukethwe kwezobuchwepheshe kuphakeme kakhulu. Lolu hlobo lwesibonakaliso ludinga umphumela kanye nengqikithi. Ngenxa yokuthi i-pigment ilula kakhulu futhi ihlanganiswe nobuciko nemisebenzi yezandla, intengo yalolu hlobo lophawu nayo iphakeme kakhulu. Amaciko kufanele adwebe amashadi acacile futhi amahle, futhi aqinisekise ukuthi ingaphezulu lensimbi elipendwe ngopende libushelelezi futhi licocekile, futhi ngeke kube namamaka okupenda, amaconsi opende, izindawo zopende ezingalingani, noma ama-coatings agqinsile.

(3) : Ipholishiwe. Ngemuva kokuthi ukukhiqizwa kuqediwe, kuyadingeka ukwenza ukucubungula ukukhanya okubonakalayo. Ukuqedwa okungaphezulu kwamalebula ensimbi engagqwali kubaluleke kakhulu, ngoba ukuphela kwendawo kuhlobene ngokuqondile nokubukeka kanye nekhwalithi yomkhiqizo. Inqubo yokukhanya ingasebenzisa abasebenzi noma umshini ukuze kuzuzwe umphumela wokuqeda okuphezulu kanye nobuso obushelelezi.
