Njirimara na nka nbipụta nke ink nke mmiri na-eme maka akwụkwọ ncharaigbe chocolate
Ink dabeere na mmiri bụ ngwaahịa ink na-emekọrịta ihe na gburugburu ebe obibi nke enwetala nlebara anya zuru oke n'afọ ndị na-adịbeghị anyaigbe achịcha achịcha. Gịnị bụ ihe dị iche n'etiti ink nke dabeere na mmiri na ink ebipụta n'ozuzu ya, oleekwa isi ihe ndị dị mkpa ka e jiri mee ihe? Ebe a, Meibang ga-akọwara gị ya nke ọma.
A na-eji ink mmiri eme ihe na-ebipụta akwụkwọ corrugated ruo ogologo oge ná mba ọzọ na ihe karịrị afọ 20 n'ụlọ.

Ink mmiri na-agbanwe agbanwe ewepụtala site na rosin-maleic acid modified resin series (ọkwa dị ala) ruo usoro resin acrylic (ọkwa dị elu). Efere a na-ebi akwụkwọ na-esikwa n'efere rọba na-ebuga na efere resin. Igwe obibi akwụkwọ ejirila nke nta nke nta malite site na igwe igwe nwere otu agba ma ọ bụ agba abụọ nwere nnukwu rollers gaa na igwe FLEXO nwere agba atọ ma ọ bụ anọ.
Ngwakọta na njirimara nke inks dabeere na mmiri bụ otu ihe nke ink mbipụta n'ozuzu. Ink dabeere na mmiri na-emekarị nke agba agba, ihe nkedo, ihe inyeaka na ihe ndị ọzọ. Ndị na-agba agba bụ agba agba nke ink dabeere na mmiri, nke na-enye ink otu agba. Iji mee ka echiche ahụ na-egbuke egbuke na mbipụta flexographic, ndị na-agba agba na-ejikarị pigmenti nwere ezigbo nkwụsi ike kemịkal na ike agba dị elu; Ihe nkedo ahụ nwere mmiri, resin, ogige amine na ihe mgbaze ndị ọzọ. Resin bụ ihe kacha mkpa na inks dabere na mmiri. A na-ejikarị resin acrylic soluble eme ihe. Ngwakọta ihe nkedo na-emetụta kpọmkwem ọrụ adhesion, ọsọ ihicha, arụmọrụ mgbochi, wdg nke ink, ma na-emetụtakwa gloss na ink nnyefe nke ink. Amine ogige tumadi na-edobe alkaline PH uru nke mmiri dabeere ink, nke mere na acrylic resin nwere ike inye mma obibi akwụkwọ mmetụta. Mmiri ma ọ bụ ndị ọzọ organic solvents na-tumadi etisasịwo resins, Gbanwee na viscosity na ihicha ọsọ nke ink; Ihe inyeaka gụnyere: defoamer, blocker, stabilizer, diluent, wdg.
Dị ka ink dabeere na mmiri bụ ihe ncha, ọ dị mfe ịmepụta egosipụta na-eji ya, ya mere, a ga-agbakwunye mmanụ silicone dị ka onye na-emepụta ihe iji gbochie ma kpochapụ egosipụta, ma melite arụmọrụ nnyefe nke ink. A na-eji ihe mgbochi na-egbochi ọsọ ihicha nke ink dabeere na mmiri, gbochie ink ka ọ ghara ihicha na mpịakọta anilox ma belata mado. The stabilizer nwere ike mezie PH uru nke ink, na nwekwara ike iji dị ka a diluent ibelata viscosity nke ink. A na-eji ihe na-esi ísì ụtọ na-ebelata agba nke ink dabeere na mmiri, a pụkwara iji ya mee ihe dị ka ihe na-egbuke egbuke iji meziwanye nchapụta nke ink dabeere na mmiri.
