Inani lezithasiselo zokugqoka ekugqokeni lincane kakhulu, kodwa linganikeza ukumboza izakhiwo ezinhle kakhulu zemishini kanye nezakhiwo zamakhemikhali ezinzile, futhi sekuyisici esibalulekile sokugqoka.I-Thickener uhlobo lwezithako zepende.Isigaba esibaluleke kakhulu sezithasiselo zokugqoka emanzini ane-viscosity ephansi.Okuqukethwe kwamanzi kukhulu futhi uketshezi likhulu ngokuqhathaniswa, okudinga ukwengeza ama-thieners athile ukuze kuncishiswe i-viscosity yawo.Ngaphezu kwalokho, upende we-latex uvame ukuhlangana nezinkinga zokuhlukaniswa kwamanzi ngesikhathi sokukhiqiza, ukuthutha, ukugcinwa, nokwakhiwa.Nakuba ingase ibambezeleke ngokwandisa i-viscosity nokuhlakazwa kopende we-latex, imiphumela enjalo yokulungiswa ngokuvamile ilinganiselwe futhi ibaluleke kakhulu.Noma ngokukhetha i-thickener kanye nokusetshenziswa kwayo ukuxazulula le nkinga.
I-Disperse Dyestuff Printing Thickener
Indima ye-thickener eyodwa Vimbela upende ukuthi ungantengantengi lapho upenda izindawo ezime mpo.I-Disperse Dyestuff Printing Thickener iyisengezo samakhemikhali e-rheological.Inhloso yayo eyinhloko ukukhulisa ukungaguquguquki, ukulawula izici eziqondile zemikhiqizo ewuketshezi, ukuthuthukisa uketshezi kanye nokulinganisa, nokuvimbela ukwenzeka kokwakhiwa.Isimo esinciphayo, ikakhulukazi ezindongeni eziqondile noma emakhoneni nasemakhoneni, singapendwa kahle kakhulu.Umdwebo ufana kakhulu futhi umbala ugcwele, ongeke uthinte inqubo elandelayo.Upende ngaphandle kwe-thiener kapende uzogeleza njengamanzi.Indima ye-thickener ezimbili Isitoreji esizinzile sikapende.I-thickener yopende inezici zamakhemikhali ezinzile futhi ingahlala kahle nezithasiselo ezihlukahlukene zopende, ngakho-ke ingabonakali iyancipha futhi i-delamination, futhi ingavimbela upende ukuthi ungahlali.Ngemuva kokuthi upende lwengezwe nge-thickener kapende, i-viscosity iyanda, engavimbela izinhlayiya ezihlakazekile zopende kusukela ekuhlanganiseni kanye nemvula ngesikhathi sokugcina, ngaleyo ndlela kuzuzwe isitoreji esizinzile.Umphumela we-thickener wesithathu Lawula ukugeleza kopende.Ukwengezwa kwe-thickener kapende kungandisa isikhathi sokwenza ifilimu kapende, kunciphise ukuconsa nokuchaphaza ngesikhathi sokumboza nge-roller noma ukuxubha, ukuze kuzuzwe umsebenzi wokulinganisa ifilimu yokuhlanganisa.I-coating thickeners ingahlukaniswa ngezigaba ezimbili ngokusho kwezinhlobo zabo I-thickener non-associative ingathuthukisa ngokuphumelelayo i-viscosity ephansi ye-shear futhi yenza uhlelo lokugqoka lube ne-pseudoplasticity ephakeme.I-coating ne-non-associative thickener njengoba ukucushwa kwe-thickener eyinhloko kunesakhiwo sejeli esiphezulu.Kubandakanya: i-inorganic, i-cellulose ether, i-alkali-evuvukala i-acrylic thickener;I-associative thickener i-hydrophobic associative water-soluble polymer, ngokuvamile ibhekisela ku-polymer encibilika emanzini enenani elincane lamaqembu e-hydrophobic ochungechungeni lwe-hydrophilic macromolecular, okuhlanganisa: i-hydrophobically modified alkali-svulled thickener, Non-ionic polyurethane, i-hydrophobically cellulose modified cell. .I-thickener enhle kufanele ihlangabezane nezidingo ezilandelayo: Thuthukisa i-viscosity kapende futhi uvimbele ukuhlukaniswa kopende ngesikhathi sokugcina, Yehlisa i-viscosity lapho udweba ngesivinini esikhulu, Ngemva kokudweba, ukwandisa i-viscosity yefilimu yokugqoka futhi uvimbele ukugoqa.Ukugcinwa kwesijiya sikapende Isishunqisi sikapende kufanele sigcinwe endaweni enezinga lokushisa elingu-5~40℃, futhi indawo yokugcina kufanele yome futhi ingenise umoya.Uma umkhiqizo ubanda ngephutha, kufanele uncibilikiswe emanzini afudumele futhi uxutshwe kahle.Ukwengeza, okokuqinisa upende kufanele futhi kugcinwe esitsheni sokuqala, noma kwenye ingilazi, izitsha zensimbi engagqwali, ipulasitiki noma i-epoxy resin enomugqa, hhayi ezitsheni ezine-carbon steel, ithusi noma i-aluminium.
