Qodobbada Khadka Saameeya Dhallaanka Daabacaadda
1 dhumucda filimka khad
Waraaqda si loo kordhiyo nuugista khad ka dib xiriiriyaha, xiriiriyaha soo haray ayaa weli lagu hayaa filimka khad, kaas oo si wax ku ool ah u wanaajin kara dhalaalka daabacaadda. Marka uu sii dhumuc weyn yahay filimka khadku, ayaa inta ka sii badan isku xidhaha soo hadhay, ayaa sii kordhinaya hagaajinta dhalaalka daabacaadda.
Gloss la kororka dhumucda filimka khad iyo korodhka, inkastoo khad isku mid ah, laakiin formation of gloss print warqad kala duwan la dhumucdiisuna waxay of filimka khad iyo isbedel waa ka duwan yahay. Warqad daahan High gloss filimka khad waa dhuuban, daabac gloss la korodhka dhumucda filimka khad oo la yareeyo, tani waxa sabab u ah filimka khad maaskaro warqad laftiisa dhalaalid sare asalka asalka ah, iyo filimka khad laftiisa sameeyey by gloss iyo ay sabab u tahay. nuugista warqadda oo la yareeyo; iyada oo si tartiib tartiib ah u kordheysa dhumucda filimka khad, warqadda nuugista walxaha isku xidhka ah ayaa asal ahaan ka buuxsamay ka dib markii ay korodhay tirada isku dhafka ah ee lagu hayo dusha sare, dhalaalkuna si joogto ah ayuu u fiicnaanayaa.
Baakadaha dahaarka leh ayaa daabacaadaha dhalaalaya iyadoo kororka dhumucda filimka khadku ay si dhakhso ah u kordheyso, dhumucda filimka khadku waxay korodhay ilaa 3.8μm ka dib markii dhalaaliddu aanay sii kordhin doonin korodhka dhumucda filimka khad.
2 Dheecaan khad
Dheecaanka khadku aad buu u weyn yahay, dhibicdu way korodhaa, cabbirka daabacaadda waa la ballaadhiyay, lakabka khadku wuu dhuuban yahay, dhalaalka daabacadu waa liitaa; dareeraha khadku aad buu u yar yahay, dhalaalkiisu sarreeyo, khadku ma fududa in la wareejiyo, laakiin sidoo kale kuma habboona daabacaadda. Sidaa darteed, si aad u hesho dhalaal wanaagsan, waa in la xakameeyaa dareeraha khad, ma aha mid aad u weyn oo aan aad u yareyn.
3King heerka
Habka daabacaadda, heerka qalinku wuu fiican yahay, ka dibna dhalaalidku wuu fiican yahay; heerka liidata, si fudud loo jiidi karo, ka dibna dhalaaliddu waa liidataa.
4Maaddada midabka khad ku jirta
Maaddada midabka sare ee khadku waxay samayn kartaa tiro badan oo kaabayaal yaryar oo ku dhex jira filimka khad. Iyo kuwan tirada badan ee xajinta xididdada ganaaxa ee awoodda isku xirka walxaha, marka loo eego dusha warqadda ee farqiga fiber si loo nuugo awoodda isku xirka walxaha ayaa aad uga weyn. Sidaa darteed, marka la barbar dhigo khadyada ka kooban midabka midabkiisu yar yahay, khadadka leh maadada midabka sare waxay ka dhigi kartaa filimka khadku inuu sii hayo xiriiriye badan. Dhallaanka walaxda daabacan ee la isticmaalayo khad ay ka kooban yihiin midab sare ayaa ka sarreeya khadyada midabkoodu yar yahay. Sidaa darteed, qaab-dhismeedka shabakada xididada ee ka dhex jira qaybaha midabka khadku waa qodobka ugu muhiimsan ee saameeya dhalaalka daabacaadda.
Daabacaadda dhabta ah, isticmaalka habka saliidda gloss si loo kordhiyo gloss ee daabacaadda, habkani gabi ahaanba wuu ka duwan yahay habka kordhinta midabka midabka ee khad. Labadan hab si loo kordhiyo gloss ee daabacaadda ee codsiga, sida ay qaybaha khad iyo daabacaadda dhumucda filimka khad si ay u doortaan.
Habka kordhinta nuxurka midabka ayaa xaddidaya baahida loo qabo soo saarista midabka daabacaadda midabka. Khad lagu sameeyay qaybo yaryar oo midab leh, marka nuxurka midabku hoos u dhaco, dhalaalka daabacadu wuu yaraadaa, kaliya marka filimka khadku uu dhumuc weyn yahay si uu u soo saaro dhalaal sare. Sidaa darteed, habka loo kordhiyo nuxurka midabka waxaa loo isticmaali karaa in lagu wanaajiyo dhalaalka walxaha daabacan. Si kastaba ha ahaatee, qadarka midabka kaliya waxaa lagu kordhin karaa ilaa xad gaar ah, haddii kale waxa ay noqon doontaa sabab u ah qayb ka midabka aan si buuxda loo dabooli karaa by walxaha isku xidha, si ay ifafaale kala firdhiso iftiinka dusha filimka khad waa ka sii daraysaa halkii keentay in a hoos u dhigida dhalaalka ee arrinta daabacan.
5Cabirka qaybaha midabka iyo heerka kala firdhisanaanta
Cabbirka qaybaha midabada ee gobolka kala firdhiyey ayaa si toos ah u go'aaminaya xaaladda kaaboolka filimka khad, haddii qaybaha khadku ay yar yihiin, waxay samayn kartaa xidido yaryar oo dheeraad ah. Kordhi awoodda filimka khadku si uu u sii haysto xidhiidhiyaha oo loo hagaajiyo dhalaalka daabacaadda. Isla mar ahaantaana, haddii qaybaha midabada si fiican loo kala firdhiyo, waxay sidoo kale ka caawisaa sameynta filim khad siman, kaas oo hagaajin kara dhalaalka daabacaadda. Qodobbada xukuma ee saameeya heerka kala firdhisanaanta qaybaha midabada ayaa ah pH ee qaybaha midabka iyo cadadka walxaha kacsan ee khadka. Kala firdhinta qaybaha midabku way fiican tahay marka qiimaha pH ee midabku hooseeyo oo waxa ku jira walxaha isbeddelaya ee khadku ay sarreeyaan.
6 Hufnaanta khad
Ka dib marka filimka khadku uu sameeyo khad hufnaan sare leh, qayb ka mid ah iftiinka dhacdada ayaa ka muuqanaya dusha sare ee filimka khad, qaybta kalena waxay gaartaa dusha sare ee warqadda oo mar kale dib u milicsato, samaynta laba midab oo kala duwan, iyo tan. milicsiga adag wuxuu kobciyaa saameynta midabka; halka filimka khad ee uu sameeyay midab-madow uu yahay mid dhalaalaya oo keliya muraayadda dusha sare, iyo saamaynta dhalaalku hubaal maaha mid u fiican sida khad hufan.
7 dhaldhalaalka walxaha isku xidha
Iftiiminta walxaha isku xira ayaa ah qodobka ugu muhiimsan ee haddii daabacaadda khadku ay soo saari karaan gloss, qalabka hore ee isku xirka saliidda linseed, saliid tung, saliid catalpa iyo saliidaha kale ee khudradda, jilicsanaanta dusha filimka ka dib filimka waa ma sarreeyaa, kaliya waxay muujin kartaa dusha sare ee filimka dufanka leh, iftiinka dhacdada si ay u sameeyaan milicsiga fidinta, dhalaalka daabacaadda ayaa liita. Maalmahan, qalabka isku xidha khadku waxa uu inta badan ka kooban yahay xabagta, iyo silaanshaha dusha sare ee khadku dahaarka ka dib waa mid sarreeya, iyo muujinta faafidda ee iftiinka dhacdada waa la dhimay, sidaas awgeed dhalaalka khadku dhowr jeer ayuu ka sarreeyaa kan khadkii hore.
8Qaabka qalajinta
Qadar isku mid ah oo khad ah oo la isticmaalayo qaabab kala duwan oo qalajin ah, gloss ma aha mid isku mid ah, guud ahaan qalajinta filimka oxidized marka loo eego gloss qalajinta qalajinta waa mid sarreeya, sababtoo ah qalajinta filimka oxidized ee khad ee walxaha isku xidhka samaynta filim ka badan.
Sidee loo hagaajiyaa dhalaalka daabacaadda?
1 Iska yaree emulsification khad
Iska yaree heerka emulsification khad. Daabacaadda Offset ee emulsification khad inta badan waxaa sababa hawlgalka biyaha iyo khad, daabacadu waxay u egtahay lakab qaro weyn oo khad ah, laakiin molecules khad ee xaalada saliidda ee biyaha, dhalaalka qalajinta aad ayuu u liitaa, waxayna soo saari doontaa taxane ah. guuldarrooyinka kale.
2 daro ku haboon
Ku dar kaabayaal ku habboon khad, waxaad hagaajin kartaa daabacaadda qalinka si aad u fududaato daabacaadda. Kaaliyeyaasha guud ee lagu daro qadarka khad, waa in aan ka badnayn 5%, haddii aad tixgeliso saamaynta gloss, waa in ay yaraadaan ama aan la dhigin. Laakiin surfactant fluorocarbon waa ka duwan yahay, waxay ka hortagi kartaa lakabka khad ee diirka orange, laalaabkii iyo cilladaha kale ee dusha, iyo isla mar ahaantaana hagaajin karaa dusha sare ee dhalaalaya daabacaadda.
3 Isticmaalka saxda ah ee saliidda qalajinta
Isticmaalka saxda ah ee saliidda qalajinta. Khad heer sare ah oo dhalaalaysa oo deg-deg ah, marka laga hadlayo heerkulka iyo qoyaanka waa caadi, lafteedu waxay leedahay awood qalajin oo ku filan.
Xaaladahan soo socda, saliidda qalajinta waa in lagu daraa:
① Xaaladda heerkulka hooseeya iyo qoyaanka jiilaalka;
② khad waa in lagu daraa xabag-diidka, ka-hortagga xabagta, saliida hagaajinta khad khafiifka ah, iwm, waa in lagu daraa saliidda qalajinta.
Hawlgalka geeddi-socodka, isticmaalka saxda ah ee saliidda qalalan, ee samaynta gloss alaabta la dhammeeyey waa mid aad u wanaagsan. Tani waa sababta oo ah warqadda si ay u nuugaan walxaha isku-xidhka ahi waxay u baahan yihiin wakhti go'an, habka, sida ugu dhakhsaha badan ee suurtogalka ah si loo sameeyo isku-xidhka walxaha isku-xidhka ah, ilaa filimku qalalan yahay, waa furaha gloss alaabta la dhammeeyey.
4 Hagaajinta Mashiinka
Si sax ah u hagaaji mashiinka. Haddii dhumucda lakabka khad ee daabacadu ay gaarto heerka, sidoo kale waxay saameyn ku leedahay dhalaalka. Tusaale ahaan: hagaajinta cadaadiska liidata, heerka fidinta dhibcaha ayaa sarreeya, dhumucda lakabka khadku ma buuxinayo heerka, dhalaalka alaabta la dhammeeyey ayaa waxoogaa ka sii daraya. Sidaa darteed, si loo hagaajiyo cadaadiska, si loo xakameeyo heerka fidinta dhibcaha ee ku saabsan 15%, lakabka khad daabacan ee daabacan waa dhumuc weyn, heerka iyo jiid furan, gloss ayaa sidoo kale jira.
5 Hagaaji fiirsashada khadka
Ku dar biyo Fanli (Saliid No. 0), viscosity saliidani aad buu u weyn yahay, dhumucdiisuna waa, waxay hagaajin kartaa xoogga khadka, si khad khafiif ah u dhumucdo, u kordhiyo dhalaalka alaabta daabacan.
