Litšobotsi le litsebo tsa khatiso tsa enke e thehiloeng metsing bakeng sa pampiri ea masenkelebokose la chokolete
Enke e thehiloeng metsing ke sehlahisoa sa enke se se nang tikoloho se fumaneng tlhokomelo e atileng lilemong tsa morao tjenalebokose la pastry. Phapang ke efe pakeng tsa enke e thehiloeng metsing le enke e akaretsang ea khatiso, ’me ke lintlha life tse hlokang tlhokomelo ha li sebelisoa? Mona, Meibang o tla u hlalosetsa eona ka botlalo.
Enke ea metsi e 'nile ea sebelisoa ho hatisa pampiri ea masenke ka nako e telele linaheng tse ling le ka lilemo tse fetang 20 lapeng. Khatiso ea pampiri e entsoeng ka masenke e tsoetse pele ho tloha khatisong ea loto (khatiso ea lithuso), khatiso ea offset (printing ea offset) le khatiso ea rabara e hlatsuoang ka metsi ho fihlela khatisong ea kajeno e bonolo ea liphallelo e thehiloeng metsing. Enke e feto-fetohang e thehiloeng metsing e boetse e ntlafalitse ho tloha ho rosin-maleic acid modified resin series (tlaase grade) ho isa ho acrylic resin series (high grade). Letlapa la khatiso le boetse le tloha poleiting ea rabara ho ea poleiti ea resin. Mochine oa khatiso o boetse o tsoetse pele butle-butle ho tloha mecheng ea mebala e le ’ngoe kapa ea mebala e ’meli e nang le lirolara tse khōlō ho ea ho ea mebala e meraro kapa ea mebala e mene ea FLEXO.
Sebopeho le litšoaneleho tsa li-inks tse thehiloeng metsing li tšoana le tsa li-inks tse tloaelehileng tsa khatiso. Li-inks tse thehiloeng metsing hangata li entsoe ka li-colorants, li-binders, li-axiliary le likarolo tse ling. Li-colorants ke mebala ea enke e thehiloeng metsing, e fang enke 'mala o itseng. E le ho etsa hore setšoantšo se be se khanyang khatisong ea flexographic, hangata li-colorants li sebelisa li-pigments tse nang le botsitso bo botle ba lik'hemik'hale le matla a phahameng a mebala; Setlama se na le metsi, resin, metsoako ea amine le metsoako e meng ea tlhaho. Resin ke karolo ea bohlokoa ka ho fetisisa li-inks tse thehiloeng metsing. Hangata ho sebelisoa resin ea acrylic e qhibilihang ka metsi. Karolo ea binder e ama ka ho toba mosebetsi oa ho khomarela, lebelo la ho omisa, ts'ebetso e khahlanong le ho khomarela, joalo-joalo ea enke, hape e ama phetiso ea gloss le enke ea enke. Lik'hemik'hale tsa Amine li boloka boleng ba PH ea alkaline ea enke e thehiloeng metsing, e le hore resin ea acrylic e ka fana ka phello e ntle ea khatiso. Metsi kapa tse ling tse manyolo solvents haholo-holo qhibiliha resin, Fetola viscosity le ho omisa lebelo la enke; Lisebelisoa tse thusang haholo-holo li kenyelletsa: defoamer, blocker, stabilizer, diluent, joalo-joalo.
Kaha enke e thehiloeng metsing ke sesepa, ho bonolo ho hlahisa li-bubble tse sebelisoang, kahoo oli ea silicone e lokela ho kenngoa e le defoamer ho thibela le ho felisa li-bubble, le ho ntlafatsa ts'ebetso ea phetisetso ea enke. Li-blockers li sebelisetsoa ho thibela lebelo la ho omisa la enke e thehiloeng metsing, ho thibela enke ho omella holim'a anilox roll le ho fokotsa pente. The stabilizer e ka fetola boleng ba PH ea enke, hape e ka sebelisoa e le mokelikeli ho fokotsa viscosity ea enke. Mokelikeli o sebelisoa ho fokotsa 'mala oa enke e thehiloeng metsing, hape e ka sebelisoa e le sehlaseli ho ntlafatsa khanya ea enke e thehiloeng metsing. Ho phaella moo, boka ba boka bo lokela ho kenngoa ho enke e thehiloeng metsing ho eketsa ho hanyetsa ha eona.
Enke e thehiloeng metsing e ka kopanngoa le metsi pele e omisoa. Hang ha enke e omme, e ke ke ea hlola e qhibiliha ka metsing le ka enke. Ka hona, enke e thehiloeng metsing e tlameha ho tsosoa ka botlalo pele e sebelisoa ho boloka junifomo ea sebopeho sa enke. Ha o kenya enke, haeba enke e setseng ka tanka e na le litšila, e lokela ho tlhotloa pele, ebe e sebelisoa ka enke e ncha. Ha u hatisa, u se ke ua lumella enke hore e ome holim'a moqolo oa anilox ho qoba ho thibela lesoba la enke. Ho thibela phetiso ea bongata ba enke ho baka ho se tsitse ha khatiso. Nakong ea khatiso, flexplate e lokela ho lula e kolobisitsoe ke enke ho qoba ho thibela mokhoa oa mongolo holim'a poleiti ea khatiso ka mor'a hore enke e ome. Ho phaella moo, ho fumanoa hore ha viscosity ea enke e thehiloeng metsing e phahame hanyenyane, ha hoa lokela ho eketsa metsi ka mokhoa o sa tloaelehang ho qoba ho ama botsitso ba enke. U ka eketsa palo e nepahetseng ea stabilizer ho e lokisa.
