Kwalban gilashiRufi muhimmin hanyar magance saman fuska ne a fannin marufi na kwalliya. Yana ƙara kyakkyawan launi ga akwatin gilashin. A cikin wannan labarin, mun raba wani labarin game da maganin fesa saman kwalban gilashi da ƙwarewar daidaita launi.
Ⅰ, ƙwarewar fesa fenti na kwalbar gilashi
1. Yi amfani da ruwa mai tsafta ko mai tacewa don daidaita fenti zuwa ga ɗanɗano mai dacewa don fesawa. Bayan aunawa da na'urar aunawa ta Tu-4, ɗanɗano mai dacewa yawanci yana tsakanin daƙiƙa 18 zuwa 30. Idan babu na'urar aunawa a yanzu, za ku iya amfani da hanyar gani: a juya fenti da sanda (ƙarfe ko sandar katako) sannan a ɗaga shi zuwa tsayin 20 cm sannan a tsaya don a lura. Idan fenti bai karye ba cikin ɗan gajeren lokaci (daƙiƙa kaɗan), ya yi kauri sosai; idan ya karye da zarar ya bar gefen saman bokitin, ya yi siriri sosai; idan ya tsaya a tsayin 20 cm, fentin yana cikin layi madaidaiciya kuma yana tsayawa yana diga ƙasa nan take. Wannan ɗanɗano ya fi dacewa.
2. Ya kamata a sarrafa matsin iska a 0.3-0.4 MPa (3-4 kgf/cm2). Idan matsin ya yi ƙasa sosai, ruwan fenti ba zai yi atom ba sosai kuma ramin zai fito a saman; idan matsin ya yi yawa, zai yi laushi cikin sauƙi kuma hazo na fenti zai yi girma da yawa, wanda zai ɓata kayan aiki kuma ya shafi lafiyar mai aiki.
3. Nisa tsakanin bututun ƙarfe da saman gabaɗaya shine 200-300 mm. Idan ya yi kusa sosai, zai yi laushi cikin sauƙi; idan ya yi nisa sosai, hazo mai fenti zai yi daidai kuma ramin zai bayyana cikin sauƙi, kuma idan bututun ƙarfe yana da nisa da saman, hazo mai fenti zai tashi a hanya, wanda zai haifar da ɓarna. Ya kamata a daidaita takamaiman girman tazara daidai gwargwadon nau'in, danko da matsin iska na fentin kwalban gilashi. Tazarar fesa fenti a hankali na iya zama mafi nisa, kuma yana iya zama mafi nisa lokacin da danko ya yi siriri; lokacin da matsin iska ya yi yawa, tazarar na iya zama mafi nisa, kuma yana iya zama mafi kusa lokacin da matsin ya yi ƙarami; abin da ake kira kusa da nesa yana nufin kewayon daidaitawa tsakanin 10 mm da 50 mm. Idan ya wuce wannan kewayon, yana da wuya a sami fim ɗin fenti mai kyau.
4. Ana iya motsa bindigar feshi sama da ƙasa, hagu da dama, zai fi dacewa a daidai gudun mita 10-12/min. Ya kamata a fesa bututun feshi a saman abin, kuma a rage feshi mai kaifi. Lokacin feshi a duk ƙarshen saman, ya kamata a saki hannun da ke riƙe da abin kunna bindigar feshi da sauri don rage hazo mai fenti, saboda ƙarshen saman abin sau da yawa yana karɓar feshi sama da biyu, kuma sune wuraren da ake iya samun digo.
5. Lokacin fesawa, ya kamata a danna 1/3 ko 1/4 na layin da ya gabata, don kada ya zube. Lokacin fesa fenti mai busarwa da sauri, ya zama dole a fesa shi a jere a lokaci guda. Sakamakon sake fesawa bai dace ba.
6. Lokacin fesawa a wuri mai buɗewa a waje, a kula da alkiblar iska (bai dace a yi aiki a lokacin da iska mai ƙarfi ta yi ƙarfi ba), kuma mai aiki ya kamata ya tsaya a alkiblar iskar don hana hazo daga hura fenti a kan fim ɗin fenti da aka fesa da kuma haifar da abin kunya a saman.
7. Tsarin fesawa yana da wahala da farko, sauƙi daga baya, ciki da farko, waje daga baya. Babban farko, ƙasa daga baya, ƙaramin yanki da farko, babban yanki daga baya. Ta wannan hanyar, hazo da aka fesa daga baya ba zai fantsama kan fim ɗin fenti da aka fesa ba kuma ya lalata fim ɗin fenti da aka fesa.
Ⅱ, ƙwarewar daidaita launi na fenti na kwalban gilashi
1. Ka'idar asali ta launi
Ja + rawaya = lemu
Ja + shuɗi = shunayya
Rawaya + shunayya = kore
2. Ka'idar asali ta launuka masu dacewa
Ja da kore suna da alaƙa, wato, ja na iya rage kore, kuma kore na iya rage ja;
Rawaya da shunayya suna da alaƙa, wato, rawaya na iya rage shunayya, shunayya kuma na iya rage rawaya;
Shuɗi da lemu suna da alaƙa, wato, shuɗi zai iya rage lemu, kuma lemu zai iya rage shuɗi;
3. Ilimin asali game da launi
Gabaɗaya, launin da mutane ke magana a kai yana kasu kashi uku: launi, haske da kuma cikakken launi. Ana kuma kiran launi da launi, wato ja, lemu, rawaya, kore, cyan, shuɗi, shunayya, da sauransu; haske kuma ana kiransa haske, wanda ke bayyana haske da duhun launi; cikakken launi kuma ana kiransa chroma, wanda ke bayyana zurfin launin.
4. Ka'idojin asali na daidaita launi
Gabaɗaya, kada a yi amfani da fiye da nau'ikan fenti uku don daidaita launi. Haɗa ja, rawaya da shuɗi a wani rabo na iya samun launuka daban-daban na tsaka-tsaki (watau launuka masu launuka daban-daban). Dangane da launuka na farko, ƙara fari zai iya samun launuka masu cikewa daban-daban (watau launuka masu launuka daban-daban). Dangane da launuka na farko, ƙara baƙi zai iya samun launuka masu haske daban-daban (watau launuka masu haske daban-daban).
5. Dabaru na asali na daidaita launi
Haɗawa da daidaita launuka suna bin ƙa'idar launi mai ragi. Launuka uku na farko sune ja, rawaya da shuɗi, kuma launukan haɗin gwiwar su sune kore, shunayya da lemu. Abin da ake kira launukan haɗin gwiwa launuka biyu ne na haske da aka haɗa a wani rabo don samun farin haske. Launin haɗin gwiwa na ja kore ne, launin haɗin gwiwa na rawaya shunayya ne, kuma launin haɗin gwiwa na shuɗi orange ne. Wato, idan launin ya yi ja sosai, za ku iya ƙara kore; idan ya yi rawaya sosai, za ku iya ƙara shunayya; idan ya yi shuɗi sosai, za ku iya ƙara lemu. Launuka uku na farko sune ja, rawaya, da shuɗi, kuma launukan haɗin gwiwa su ne kore, shunayya, da lemu. Launuka masu haɗin gwiwa launuka biyu ne na haske da aka haɗa a wani rabo don samun farin haske. Launin haɗin gwiwa na ja kore ne, launin haɗin gwiwa na rawaya shunayya ne, kuma launin haɗin gwiwa na shuɗi orange ne. Wato, idan launin ya yi ja sosai, za ku iya ƙara kore; idan ya yi rawaya sosai, za ku iya ƙara shunayya; idan ya yi shuɗi sosai, za ku iya ƙara lemu.
Kafin a daidaita launuka, da farko a tantance matsayin launin da za a daidaita bisa ga hoton da ke ƙasa, sannan a zaɓi launuka biyu masu kama da juna don su dace da wani rabo. Yi amfani da kayan allon kwalban gilashi ɗaya ko kayan aikin da za a fesa don daidaita launin (kauri na substrate, kwalban gilashin gishirin sodium da kwalban gilashin gishirin calcium za su nuna tasirin daban-daban). Lokacin daidaita launin, da farko a ƙara babban launi, sannan a yi amfani da launin mai ƙarfin launi mai ƙarfi azaman launi na biyu, a hankali a ƙara a hankali a ci gaba da juyawa, kuma a lura da canje-canjen launi a kowane lokaci, a ɗauki samfura a goge, a goge, a fesa ko a tsoma su a cikin samfurin tsabta, kuma a kwatanta launin da samfurin asali bayan launin ya daidaita. Dole ne a fahimci ƙa'idar "daga haske zuwa duhu" a cikin dukkan tsarin daidaita launuka.
