Hey! Olsem wanpela saplaia bilong ol 'wetting agent', mi bin lukim stret olsem wanem ol dispela liklik samting inap long wokim ol gutpela samting long ol ink we i gat wara - long en. Orait, yumi go insait na toktok long hau ol 'wetting agents' i save helpim wok bilong ol ink we i gat wara - long en.
Pastaim, yumi ken kliagut long wanem samting em ol ink we i gat wara - long en. Ol i wanpela samting we planti manmeri i save laikim long dispela taim bikos ol i no bagarapim envairomen taim yu skelim wantaim ol ink we i gat solvent - long en. Ol i save yusim wara olsem nambawan samting bilong karim ol kala na ol narapela samting. Tasol wara i gat ol salens bilong en yet taim em i kam long yusim ink.
Wanpela bikpela hevi wantaim ol ink we i gat wara - em 'surface tension' bilong ol. Wara i gat bikpela 'surface tension', we i min olsem em i save go antap long ol samting na i no save go aut wankain. Dispela inap long kamapim nogut 'coverage' na 'printing' risal i no wankain. Em ples we ol 'wetting agents' i save kam insait long en.
Ol 'wetting agents', ol i save kolim tu olsem 'surfactants', em ol molekiul we i gat wanpela 'hydrophilic' (wara - laikim) pinis na wanpela 'hydrophobic' (wara - heting) pinis. Taim ol i putim long ol ink we i gat wara long en, ol i save daunim strong bilong ink. Dispela i larim ink long go aut isi long ples bilong prinim, maski em i pepa, plastik, o narapela samting.
Yumi ken lukluk gut long hau dispela i wok. Taim ol i putim wanpela 'wetting agent' long ink, hap bilong 'surfactant molekiul' we i no laikim wara i pas long pes bilong 'substrate', na hap bilong 'hydrophilic' i stap yet insait long ink. Dispela i kamapim wanpela liklik hap we i daunim 'surface tension' namel long ink na 'substrate'. Olsem na, ink inap long ron gut na karamapim gut pes bilong en.
Narapela gutpela samting bilong yusim ol 'wetting agents' insait long ol wara - beis ink em i gutpela 'pigment dispersion'. Ol kala em ol liklik hap kala insait long ink we i save givim kala long en. Insait long ol ink we ol i yusim wara -, sampela taim ol kala i save bung wantaim, na dispela inap long mekim kala i no wankain na i no gutpela long prinim. Ol samting bilong mekim ink i wet i helpim long rausim ol kala i go long olgeta hap bilong ink.
Ol molekiul bilong 'wetting agent' i raunim ol 'pigment particles', na i pasim ol long bung wantaim. Dispela i mekim na ol kala i stap wankain insait long ink, na dispela i mekim kala i kamap wankain na gutpela kwaliti bilong prinim. Em i helpim tu long stopim ol kala long sindaun long as bilong ink kontena longpela taim.
Nau, yumi ken toktok long wok bilong ol 'wetting agents' long taim bilong draim ol ink we i gat wara - long en. Ol ink we i gat wara - i save kisim longpela taim long drai taim yumi skelim wantaim ol ink we i gat solvent - bikos wara i save drai isi isi. Ol samting bilong wetim wara inap long mekim wok bilong draim i kamap hariap.
Taim ol i daunim 'surface tension' bilong ink, ol 'wetting agents' i larim wara insait long ink i go aut hariap. Dispela i kamap bikos 'surface tension' i stap daunbilo i min olsem ol wara molekiul i ken bruk isi tru long ink na go insait long win. Olsem na, ink i save drai hariap, na dispela em i wanpela bikpela gutpela samting long ol wok bilong prinim ol samting hariap tru.
Antap long mekim gutpela taim bilong draim, ol samting bilong wet i ken mekim ink i pas gut long 'substrate'. Taim ink i pas gut, em i no inap long 'rub off' o 'smudge'. Dispela em i bikpela samting tru long ol aplikesen we ol i save holim o putim ol samting we ol i prinim long ples we ol i ken bagarap.
Wetting agent i helpim long kamapim strongpela bon namel long ink na sabstret long rot bilong daunim pes eneji bilong sabstret. Dispela i larim ink long wetim gut pes na kamapim wanpela gutpela samting bilong pasim.
Tasol hau bai yu makim gutpela wet agent bilong ol wara - beis ink bilong yu? I gat sampela samting yu mas tingim. Pastaim, yu mas tingim wanem kain 'substrate' yu bai prinim long en. Ol narapela narapela 'substrates' i gat ol narapela narapela 'surface properties', na yu mas i gat wanpela 'wetting agent' we inap long daunim 'surface tension' bilong dispela 'substrate'.
Yu mas tingim tu sapos 'wetting agent' i ken wok wantaim ol narapela samting insait long ink. Sampela 'wetting agents' inap long wok wantaim ol narapela samting insait long ink, na dispela inap long kamapim ol hevi olsem 'foam' o 'ink' i no inap stap gut. Em i bikpela samting long traim 'wetting agent' insait long 'ink formulation' bilong yu long meksua olsem em i wok gut wantaim olgeta arapela samting.
Long kampani bilong mipela, mipela i save givim planti kain kain marasin bilong wet we ol i wokim stret long ol ink we i gat wara - long en. Ol i bin testim na pruvim olsem ol prodak bilong mipela i save helpim ol ink we i gat wara - long en long kain kain wok. Maski yu wok long prinim long pepa, plastik, o ol narapela samting, mipela i gat wanpela 'wetting agent' we inap long inapim ol nid bilong yu.
Sapos yu laik save moa long hau ol 'wetting agents' bilong mipela i ken helpim ol 'water - ink' bilong yu long wok gut, yu ken sekim4-testsdfgsdfg. Dispela pes i givim moa infomesen long ol prodak bilong mipela na wok bilong ol.
Mipela i amamas long toktok wantaim yu long ol samting yu nidim. Sapos yu laik kamapim gutpela na gutpela wok bilong ol wara - ink bilong yu, noken surik long toktok wantaim mipela. Mipela i ken wok wantaim yu long painim gutpela 'wetting agent' solusen bilong yu long 'printing' nid. Maski em i bilong wanpela liklik - skel printing projek o wanpela bikpela - skel indastriel operesen, mipela i gat olgeta samting bilong yu.
Long pinisim, ol 'wetting agents' i save mekim bikpela wok long helpim wok bilong ol ink we i gat wara - long en. Ol i save daunim strong bilong 'surface tension', mekim 'pigment' i go nabaut, mekim 'drying' i kamap hariap, na mekim 'adhesion' i pas gut. Sapos yu makim stretpela 'wetting agent', yu inap long kisim gutpela print kwaliti, hariap prodaksen taim, na moa wankain risal. Olsem na, sapos yu laik painim wanpela marasin bilong wetim wara - ink bilong yu, ringim mipela o salim wanpela email i kam long mipela. Mipela i stap hia long helpim yu long kisim printing bilong yu i go long narapela level.
