I-Hydroxypropyl Methyl Cellulose (HPMC) Esetyenziselwa Ipeyinti esekwe emanzini

Ukusebenza kwethu kokugcinwa kwamanzi e-cellulose ether kwi-latex yokwambathisa, ngokukodwa ukugquma kwe-PVA ephezulu kubonelela ngokugqwesileyo kokusebenza, ukugquma kwe-pulp enzima, akuyi kuvelisa i-flocculation;Umphumo wayo ophezulu wokuqina unokunciphisa umthamo, uphucule uqoqosho lokuqulunqwa, kwaye uphucule ukumiswa kwenkqubo yokugqoka.Iipropati ezigqwesileyo ze-rheological kwi-coating, zinokuba kwimo engatshintshiyo, zigcine eyona nto ingcono yokutyeba yengubo;Kwimeko yokulahlwa, enolwelo olugqwesileyo, kwaye ayiyi kutshiza;Kwi-coating and roller coating, kulula ukusabalalisa kwi-substrate, ukwakhiwa okufanelekileyo;Xa i-coating igqityiwe, i-viscosity yenkqubo iya kubuyiselwa ngokukhawuleza, isambatho siya kuvelisa ngokukhawuleza ukuhamba.

Kwihlabathi elidlamkileyo lepeyinti yelatex esekwe emanzini, esinye isongezo esibaluleke kakhulu yiHydroxy Propyl Methyl Cellulose.(HPMC).Ngaphandle kokuba sisityebi esisebenza kakuhle, olu hlobo longezelelo lukwabonelela ngentaphane yezinye iipropathi eziluncedo, ezinje ngobuchule bebrashi, ukuxhathisa kwe-sag, i-emulsification, amandla okunqunyanyiswa, njl.kananjaloukwenza olu hlobo lwe-thickener luthandwa kakhulu ngabavelisi bepeyinti abaninzi emhlabeni.

Isetyenziswe kwipeyinti esekwe emanzini.Ibonisa umphumo wayo obalaseleyo wokutyeba okuphezulu,kwayeiimpawu zerheological, ukusasazwa kunye nokunyibilika.Inozinzo oluhle lwe-bio, inika ixesha elaneleyo kwivenkile yepeyinti.Ukuthintela ngokufanelekileyo ii-pigments kunye ne-filler sedimentation.
