Khadka biyaha ku salaysan ee LQ-INK ee daabacaadda wax soo saarka waraaqaha
Muuqaal
1. Ilaalinta deegaanka: sababtoo ah taarikada flexographic maaha kuwo u adkaysta benzene, esters, ketones iyo dareerayaasha kale ee organic, hadda, khad biyaha ku salaysan flexographic, khad alkohol-milmi leh iyo khad UV kuma jiraan dareerayaasha sunta ah ee kor ku xusan iyo biraha culus, markaa waa cagaar iyo khad ammaan ah oo deegaanka u wanaagsan.
2. Qalajinta degdega ah: iyadoo ay ugu wacan tahay qalajinta degdega ah ee khad jilicsan, waxay dabooli kartaa baahida daabacaadda walxaha aan nuugi karin iyo daabacaadda xawaaraha sare leh.
3. Viscosity hoose: khad flexographic ah waxaa iska leh khad viscosity hoose oo leh dareere wanaagsan, kaas oo awood u siinaya mishiinka flexographic si uu u qaato nidaamka wareejinta khad anilox oo aad u fudud oo leh waxqabadka wareejinta khad wanaagsan.

Sababta ugu weyn ee khad-biyood ku salaysan flexographic
1. Wanaag
Wanaagsanaantu waa tilmaame jireed si loo cabbiro cabbirka qayb ka mid ah midabka iyo buuxinta khad, kaas oo ay si toos ah u maamusho soo saaraha khadka. Isticmaalayaashu guud ahaan way fahmi karaan mana bedeli karaan cabbirkooda isticmaalka.
2. Viscosity
Qiimaha viscosity wuxuu si toos ah u saameyn doonaa tayada walxaha daabacan, sidaas darteed mawjadaha khad biyaha ku salaysan waa in si adag loo xakameeyaa daabacaadda flexographic. Viscosity ee khad biyaha ku salaysan ayaa guud ahaan lagu kantaroolaa inta u dhaxaysa 30 ~ 60 seconds / 25 ℃ (Rinji No. 4 koob), iyo viscosity guud ahaan waxaa la xakameeyaa inta u dhaxaysa 40 ~ 50 seconds. Haddii viscosity-ku aad u sarreeyo oo hantida siman ay liidato, waxay saameyn doontaa daabacaadda qalin-biyoodka, taas oo si sahlan u horseedi karta saxan wasakh ah, saxan dhejis ah iyo ifafaale kale; Haddii viscosity-ku aad u hooseeyo, waxay saamayn doontaa awoodda sidaha si uu u wado midabka.
3.qallalan
Sababtoo ah xawaaraha qalajinta waxay la mid tahay viscosity, taas oo si toos ah uga muuqan karta tayada alaabta daabacan. Hawlwadeenku waa inuu si faahfaahsan u fahmo mabda'a qalajinta si uu si macquul ah ugu qoondeeyo wakhtiga qallajinta qalinka biyaha ku salaysan iyadoo loo eegayo badeecadaha ama substrates kala duwan. Iyadoo la hubinayo qalajinta wanaagsan ee khad biyaha ku salaysan, waa inaan sidoo kale tixgelinno viscosity dhexdhexaad ah ama qiimaha pH ee deggan.
4.PH qiimaha
Khadka aqueous wuxuu ka kooban yahay qadar go'an oo ammonium ah, kaas oo loo isticmaalo si loo hagaajiyo xasilloonida ama kor loogu qaado caabbinta biyaha ka dib daabacaadda. Sidaa darteed, qiimaha pH waa mid ka mid ah tilmaamayaasha muhiimka ah. Qiimaha pH ee khad biyaha ku salaysan marka laga baxayo warshada waxaa guud ahaan la kantaroolaa qiyaastii 9. Qiimaha pH ee mishiinka waa la hagaajin karaa ama la xakameyn karaa inta u dhaxaysa 7.8 iyo 9.3
