Iimveliso zeVitamit zonke zivela kwi-Cotton yeNdalo yePokks okanye iPulp yeWood, eveliswa nge-ether. Iimveliso ezahlukeneyo zeselfowuni zisebenzisa iiarhente ezahlukeneyo ze-ETher. Iarhente yokukhuphela isetyenziswa kwi-HydroxyEsethl Selelose (Hec) ye-Ethylene oxide, kwaye iarhente ye-ether esetyenziswe kwi-HydroxlyAsel Methylcelose (i-HPMC) zezinye iintlobo zearhente zokuphuma. (Chloromethane kunye ne-propylene oxide).
Kwipeyinti yokwenyani ye-SZOON kunye nepeyinti ye-upex, i-hydroxyythl seluplose inokusetyenziswa njenge-thickener.
Ipeyinti yelitye lokwenyani kulula ukuyitshintsha ngenxa yenani elikhulu le-agggate kunye nobungqina obukhulu. Kuyimfuneko ukongeza i-tickener yokwandisa i-viscofity yayo ukuze ihlangane nolwakhiwo olufunekayo ekutshintsheni ngexesha lokutshisa ngexesha lolwakhiwo, ukuphucula amandla okugcina, kwaye kufezekise amandla ayo.
Ukuba ufuna ipeyinti yelitye lokwenyani lokufezekisa amandla amahle, ukuxhathisa kwamanzi kunye nokungavisisiswa kwemozulu, ukukhetha izinto eziluhlaza kunye noyilo lwefomula kubaluleke kakhulu.
Phantsi kweemeko eziqhelekileyo, inani le-emulsion esetyenziswa kwipeyinti ephezulu yelitye yelitye iya kuphakama.
Umzekelo, kwitoni yelitye lokwenyani, kunokubakho i-300kg ye-enulsul ecocekileyo ye-acrylic kunye ne-650kg yesanti yamatye yelitye lendalo. Xa umxholo oqinileyo we-emulsion, ivolumu ye-300KG ye-Emolsion emva komile malunga neelitha ezili-150, kwaye ivolumu ye-650kg yentlabathi imalunga neelitha ezingama-225. Oko kukuthi, i-PVC (i-PVC (i-Pigc yeQonga) lepeyinti yelitye ingama-60% ngeli xesha, ngenxa yokuba amasuntswana eSanti yeLizwe, ipeyinti eyomileyo inokuba kwi-CPVC (i-FORTAL STERTE). I-pigment yevolumu) Ukuya kuthi ga ngoku ixhalabile, ukuba ukhetha isellulose ngohlobo olufanelekileyo, ipeyinti yelitye yokwenyani inokwenza ifilimu egcwele ipeyinti kunye nepeyinti yokufikelela kwiimfuno ezintathu eziphambili zepeyinti yelitye. Ukuba umxholo welitye lokwenyani i-Emoulsion iphantsi, kuyacetyiswa ukuba isebenzise i-selupelose kunye ne-vickosity ephezulu (enjenge-vickosity eyi-100,000), enokunciphisa inani leselsulose (enokunciphisa isixa selitye sentshukumo.
Abanye abavelisi belitye le-upostlication basebenzisa i-hydroxypropyl methylcelgalose endaweni ye-hydroxytethl seluplose yendleko kunye nezinye izinto.
Xa kuthelekiswa neentlobo ezimbini ze-seluplose, i-hydroxethyl seluplose inobugwenxa bamanzi, ayiyi kuphulukana nokugcinwa kwamanzi ngenxa ye-gelatini kubushushu obuphezulu, kwaye iyothintelo oluthile. Ukuqwalaselwa kokusebenza, kuyacetyiswa ukuba basebenzise i-hydroxythyl seluplose ngohlobo lwe-100,000 njenge-tickener yepeyinti yelitye lokwenyani.
