Ukungeniswa kwesicelo se-selselose tickener

Ipeyinti ye-Latex ngumxube wemigangatho, ukusasazeka kweentsizi kunye nokusasazeka kwe-polymer, kunye nongezizo kufuneka zisetyenziselwe ukuhlengahlengisa i-viscofity yayo ukuze ineepropathi zalo zemveliso, ukugcinwa nolwakhiwo. Ezo zinto zongezelelo zibizwa ngokuba zii-thisfuniners, ezinokunyusa i-viscofity ye-cayishini kwaye ziphucule ubume bengqolowa yengubo, ke bona babizwa ngokuba zii-thrickelogics.

Oku kulandelayo kwazisa iimpawu eziphambili zeeseli ezisetyenziswayo zeselfowuni kunye nesicelo sabo kwipeyinti ye-Latex.
Cellulosic materials that can be applied to coatings include methyl cellulose, hydroxyethyl cellulose, and hydroxypropyl methyl cellulose. Elona nqaku likhulu leLwilose tickener kukuba iziphumo zokuba iphucukile, kwaye inokunika umzobo wepeyinti, kwaye unokulibazisa ixesha elomileyo, kwaye lenze ipeyinti ineepeyinti, ukuthintela ipeyinti ekuphumeni. Ukuthintela kwakhona ngexesha lokugcina, nangona kunjalo, ezo nzondo zikwanazo nangenxa yokufakelwa kwepeyinti yepeyinti, ngakumbi xa kusetyenziswa amabanga aphezulu.

I-seluplose yinto yesondlo se-microorganisms, ngoko ke amanyathelo e-anti-mpuma kufuneka omelezwe xa eyisebenzisa. Abakhululi baseLysuloloc banokuziqhenya kuphela kwinqanaba lamanzi, kodwa abanalo ifuthe elibi kwezinye izinto kwipeyinti yepeyinti, ngenxa yoko, banokuyindisa i-vigstology yepeyinti, ephakathi ebizwa ngokuba yi-KU Viscosity).

I-1. Hydroxyyl seluplose

Inkcazo kunye neemodeli zemveliso ye-hydroxythl yeseluplose ihluleke ngokukodwa ngokwenqanaba lokufaka endaweni kunye novimba. Ukongeza umahluko kwi-viscosity, iintlobo ezahlukeneyo ze-hydroxythl sellise zinokwahlulwa kuchwetheza oqhelekileyo lohlobo oluqhelekileyo, uhlobo lokusasazeka ngokukhawuleza kunye nohlobo lokuzinza kwebhayoloji ngokuguqulwa kwinkqubo yemveliso. Ngokubhekisele kwindlela yokusetyenziswa echaphazelekayo, i-HydroxyEtheetheetheetheetheetheetheetheetheethy inokongezwa kumanqanaba ahlukeneyo kwinkqubo yemveliso yokudibana. Uhlobo lokusasazeka okukhawulezayo lunokongezwa ngokuthe ngqo kwi-powder eyomileyo, kodwa ixabiso le-pH ngaphambi kongeziweyo kufuneka lingaphantsi kwexabiso eliphantsi, kwaye emva koko kunyuke ngexabiso le-HOL ukuyenza inyibilike ngokukhawuleza. Amanyathelo ahambelanayo nawo anokusetyenziselwa ukulungiselela uxinzelelo oluthile lweglue kwaye yongeze kwinkqubo yepeyinti.

I-2. Hydroxyl methyl seluplose

Iziphumo ezihlekisayo ze-hydroxypropyl methylcelcelgalose ifana ne-hydroxythlcelose, oko kukuthi, ukwandisa amazinga okubanjwa kwamazantsi kunye aphakathi. I-Hydroxypropyl Methylcelcelsulose ixhathise ukonakalisa i-enzymatic yokuphelisa ukonakaliswa, kodwa ukulingana kwamanzi akulunganga njenge-hydroxythl sellulose, kwaye inesidima sokufudumala xa ishushu. Kwi-Hodroxypropyl ye-Hydroxypropyl Methylceltulose, inokongezwa ngokuthe ngqo emanzini xa isetyenziswa, emva kokuvuselela izinto ezifana ne-Amkaline Manzis, ilungelelanise ixabiso le-AMMONI, ivuse de inyibilike ize inyibilike. Nge-Hydroxypropyl Methylcelcelcelsulose enonyango, inokuthi ifakwe kwaye ifakwe ngamanzi ashushu ngaphezulu kwe-85 ° C ngaphambi kokusetyenziswa, emva koko ivuselele amanzi abandayo okanye amanzi omkhenkce ukuze ayichithe ngokupheleleyo.

I-3. Methyl Selelise

UMethylceluplose unepropathi efanayo kwi-HydroxyPOpylMethylcelcelcelcelose, kodwa azinzanga kwi-viscofity enobushushu.

I-HydroxyEtheetheetheetheetheetheetheethy yeyona nto isetyenziswa kakhulu kwipeyinti ye-Latex, kwaye isetyenziswa kwi-pied ephezulu, ephakathi neliphantsi ye-FARTE. Isetyenziswe ngokubanzi kwipeyinti yepeyinti yesiqhelo ye-Latex, i-Grey Calcium powder ipeyinti, njl njl. I-Methyl Selelose ayisetyenziswanga kwipeyinti ye-Latex, kodwa isetyenziswe ngokubanzi kwi-powdery ingaphakathi kunye nodonga olungaphandle lubekwe ngokupheleleyo nokugcinwa kwayo kwangoko kunye nokugcinwa kwamanzi kakuhle. I-viscosity ye-villyl ye-villyl ye-metyl selliese inokuphelisa i-Itty nge-ThiXootpy ebalaseleyo kunye nokugcinwa kwamanzi, kuyenza ibe nepropathi elungileyo yokukrokra.
