Isixa sezongezo zokwaleka kwi-coating sincinci kakhulu, kodwa sinokunika iipropathi ezigqwesileyo zoomatshini kunye neempawu ezizinzileyo zemichiza, kwaye ibe yinxalenye eyimfuneko yokwaleka.I-Thickener luhlobo lwezongezo zepeyinti.Iklasi ebaluleke kakhulu yezongezo zokugquma kwamanzi kunye ne-viscosity ephantsi.Isiqulatho samanzi sikhulu kwaye ubumanzi bubukhulu kakhulu, nto leyo ifuna ukongeza ezinye ii-thickeners ukuze zinciphise i-viscosity yayo.Ukongezelela, ipeyinti ye-latex ihlala idibana neengxaki zokuhlukana kwamanzi ngexesha lokuvelisa, ukuthutha, ukugcinwa kunye nokwakhiwa.Nangona inokulibaziseka ngokunyusa i-viscosity kunye nokusasazwa kwepeyinti ye-latex, iziphumo zohlengahlengiso ezinjalo zihlala zilinganiselwe kwaye zibaluleke ngakumbi.Okanye ngokukhetha i-thickener kunye nokusetyenziswa kwayo ukusombulula le ngxaki.
Ukusasaza i-Dyestuff yoShicilelo Thickener
Indima ye-thickener enye Thintela ipeyinti ekuhengeni xa upeyinta imiphezulu emi nkqo.Disperse Dyestuff Printing Thickener is a rheological chemical additive.Injongo yayo ephambili kukunyusa ukuhambelana, ukulawula iimpawu ezichanekileyo zeemveliso zamanzi, ukuphucula umbane kunye nokulinganisa, kunye nokuthintela ukwenzeka kokwakhiwa.Into ehexayo, ngakumbi kwiindonga ezithe nkqo okanye iikona kunye neekona, zinokupeyintwa kakuhle kakhulu.Umzobo ufana ngakumbi kwaye umbala ugcwele, ongayi kuchaphazela inkqubo elandelayo.Ipeyinti ngaphandle kokujiya ipeyinti iya kuhamba njengamanzi.Indima ye-thickener ezimbini Ukugcinwa okuzinzileyo kwepeyinti.I-thickener yepeyinti ineempawu ezizinzileyo zeekhemikhali kwaye inokuhlalisana kakuhle kunye nezongezo ezahlukahlukeneyo zepeyinti, ngoko ingabonakali iyancipha kunye ne-delamination, kwaye inokuthintela ipeyinti ukuba ihlale.Emva kokuba ipeyinti yongezwa nge-thickener yepeyinti, i-viscosity iyanda, enokuthintela amaqhekeza ahlakaziweyo epeyinti ukusuka kwi-agglomeration kunye nemvula ngexesha lokugcinwa, ngaloo ndlela ifezekisa ukugcinwa okuzinzile.Isiphumo esityebileyo sesithathu Lawula ubumanzi bepeyinti.Ukongezwa kwepeyinti yepeyinti kunokwandisa ixesha lokubumba ifilimu yepeyinti, ukunciphisa ukuvuza kunye nokutshiza ngexesha lokugubungela i-roller okanye ukuxubha, ukuze kufezekiswe umsebenzi wokulinganisa ifilimu yokugqoka.I-coating thickeners inokwahlulwa ibe ngamacandelo amabini ngokweentlobo zabo I-thickener engekho-associative inokuphucula ngokufanelekileyo i-viscosity ephantsi ye-shear kwaye yenza inkqubo yokugqoka ibe ne-pseudoplasticity ephezulu.I-coating kunye ne-non-associative thickener njengoko uqwalaselo oluphambili lwe-thickener lunesakhiwo esiphezulu se-gel.Kubandakanywa: inorganic, cellulose ether, alkali-ukudumba acrylic thickener;I-asociative thickener yi-hydrophobic associative water-soluble polymer, ngokubanzi ibhekiselele kwipolymer enyibilikayo emanzini kunye nenani elincinci lamaqela e-hydrophobic kwi-hydrophilic macromolecular chain, kubandakanywa: i-hydrophobically modified alkali-swelled thickener, i-non-ionic polyurethane, i-hydrophobically .I-thickener efanelekileyo kufuneka ihlangabezane nezi mfuno zilandelayo: Ukuphucula i-viscosity yepeyinti kwaye unqande ukuhlukana kwepeyinti ngexesha lokugcinwa, Ukunciphisa i-viscosity xa udweba ngesantya esiphezulu, Emva kokudweba, ukwandisa i-viscosity yefilimu yokugubungela kwaye uthintele ukuchithwa.Ukugcinwa kwento yokujiyisa ipeyinti Isingqimba sepeyinti kufuneka sigcinwe kwindawo enobushushu obuyi 5~40℃, kwaye indawo yokugcina kufuneka yome kwaye ingene umoya.Ukuba imveliso iqhwala ngengozi, kufuneka inyibilike emanzini afudumeleyo kwaye ixutywe kakuhle.Ukongeza, i-thickener yepeyinti kufuneka igcinwe kwi-container yokuqala, okanye kwenye iglasi, insimbi engenasici, iplastiki okanye i-epoxy resin enezikhongozeli ezifakwe kwi-carbon steel, i-copper okanye i-aluminiyam.
