Waxaan ku aragnaa waddada kuwa midabo qani ah, xayeysiis qaab weyn oo macquul ah, waa printing mishiinka sawiro.Oo marka loo eego xaaladaha isticmaalka kala duwan ee aan isticmaalno khad la mid ah ma aha, maanta xiaobian in ay ku siiyaan sharaxaad fudud ee mashiinka sawir leh khad dhowr kala duwanaansho ah:
Mashiinka sawirka waxaa inta badan loo isticmaalaa in lagu qasi karo midabka saliidda leh ee saliidda, sida saliidda macdanta, saliidda cuntada, khad ku saabsan dhexdhexaadinta daabacaadda iyada oo la gelinayo saliidda iyo midabka uumi-baxa ee ku dheggan dhexdhexaadka
Khadka warshadaha sawirada iyadoo loo eegayo isticmaalka si loo kala saaro, waxaa loo qaybin karaa laba nooc:Mid waa khad biyaha ku salaysan, kaas oo inta badan ka kooban biyo iyo dareerayaasha biyaha ku milma.
Midda kale waa, khad saliid leh, dareere aan la milmi karin oo ah qaybta ugu muhiimsan ee saldhigga midabka kala diri.
Marka loo eego milanka dareeraha, waxa kale oo loo qaybin karaa saddex nooc:
Marka hore, khad dheeha: waa khad dheeh ku salaysan, inta badan mishiinada sawirada gudaha ayaa la isticmaalayaa;
Laba, qalin midab: waxay ku salaysan tahay khad midab leh, oo loo isticmaalo mashiinka daabacaadda dibadda.
Saddex, khad dareere ah oo daciif ah: inta u dhaxaysa labada, loo isticmaalo mashiinka sawirka dibadda.
Waa in fiiro gaar ah loo yeesho xaqiiqda ah in saddexdan khad aan la wada isticmaali karin. Mashiinka biyaha ku salaysan wuxuu kaliya isticmaali karaa khad biyaha ku salaysan,Mashiinka saliidda ku salaysan wuxuu kaliya isticmaali karaa khad dareere daciif ah iyo khad dareere ah. Maaddaama kartoonka khadku, tuubada iyo biiyaha mishiinka biyaha ku salaysan iyo mishiinka saliidda ay kala duwan yihiin marka mishiinka la rakibo, khadku si aan kala sooc lahayn looma isticmaali karo.
Qodobbada saameeya tayada khadku waxay inta badan leeyihiin shan arrimood: kala firdhisan, conductivity, qiimaha PH, kacsanaanta dusha, viscosity.
1) kala firdhisan:waa surfactant ah, doorkeedu waa in la hagaajiyo sifooyinka jirka ee dusha khad, kor u affinity ee khad iyo isbuunyo, qoyaan. Sidaas guud ahaan iyada oo kaydinta isbuunyada, conducting of khad ka kooban yahay kala firdhiso.
2) Dhaqdhaqaaqa korantada:Qiimahan waxaa loo isticmaalaa si ay u muujiyaan content milix. tayada tayada wanaagsan waa in aanay ku jirin wax ka badan 0.5% cusbo si looga fogaado crystallization at nozzle. Khad saliid ah sida ay size qayb ka mid ah, go'aansato in ay isticmaalaan waxa nozzle, buufin weyn mashiinka 15PL, 35PL waa sida ay size qayb qayb si loo go'aamiyo saxsanaanta mishiinka khad, tani waa mid aad u muhiim ah.
3) Qiimaha PH:Waxaa loola jeedaa dareeraha PH, inta badan acidic xal, hoos qiimaha PH, liddi ku ah, ka badan alkaline xal, sare qiimaha PH. Si looga hortago ink daxalka dhuuban, qiimaha PH guud ahaan waa in u dhexeeya 7-12.
4) kacsanaanta dusha sare:waxay saameyn kartaa samaynta dhibco khad ah, khad tayo wanaagsan leh ayaa ah viscosity hooseeya, kacsanaanta dusha sare.
5) viscosity:taas oo ah, caabbinta qulqulka dareeraha, viscosity ee khadku aad buu u weyn yahay, waxay samayn doontaa habka daabacaadda ee sahayda khad
kala goyn;Muuqashada aad bay u yar tahay, waxay soo saari doontaa qulqulka khad habka daabacaadda. Khadka heerkulka caadiga ah ee qolka, guud ahaan waa la keydin karaa 3-6 bilood, waqti aad u dheer ama roobab, oo saameeya isticmaalka ama furka, shuruudaha ilaalinta khadku waa la xiray, ka fogow iftiinka qorraxda tooska ah, heerkulku waa inuusan noqon mid aad u sarreeya ama aad u hooseeya.
