Eyona iHydroxypropyl iMethyl Cellulose (HPMC) esetyenziselwa uMenzi wePeyinti esekwe emanzini kunye nomzi-mveliso

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

Ipeyinti esekelwe emanzini / yokugquma inikwa kuqala kunye ne-colophony, okanye ioli, okanye i-emulsion, yongeza abancedisi abahambelanayo, kunye ne-organic dissolvent okanye i-water make up kwaye ibe lulwelo oluncangathi. Ipeyinti esekelwe kumanzi okanye izambatho ezinomsebenzi omhle nazo zinentsebenzo egqwesileyo yokusebenza, amandla okugubungela kakuhle, ukunamathela okuqinileyo kwefilimu, ukugcinwa kwamanzi okulungileyo kunye nezinye iimpawu; I-ether ye-cellulose yeyona nto ifanelekileyo ekrwada ukubonelela ngezi mpawu.

Iithegi zeMveliso

Ukusebenza kwethu kokugcinwa kwamanzi kwe-cellulose ether kwi-latex coating, 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 kakhulu, 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 isiphumo sayo esihle kakhulu sokuqina,kwayeiimpawu zerheological, ukusasazwa kunye nokunyibilika. Inozinzo oluhle lwe-bio, inika ixesha elaneleyo kwivenkile yepeyinti. Ukuthintela ngokufanelekileyo ii-pigments kunye ne-filler sedimentation.
