Loluphi uhlobo lwe-thickener olusetyenziswa kwipeyinti?

I-thickener esetyenziswe kwipeyinti ngokuqhelekileyo yinto eyandisa i-viscosity okanye ubukhulu bepeyinti ngaphandle kokuchaphazela ezinye iimpawu zayo ezifana nombala okanye ixesha lokumisa. Enye yeentlobo eziqhelekileyo ze-thickener ezisetyenziswa kwipeyinti yi-rheology modifier. Ezi zilungisi zisebenza ngokuguqula indlela yokuziphatha kwepeyinti, iyenze ibe ngqindilili kwaye izinze ngakumbi.

Kukho iintlobo ezininzi ze-rheology modifiers ezisetyenziselwa ukwakheka kwepeyinti, nganye ineempawu zayo ezizodwa kunye neenzuzo. Ezinye zezona ziqhelekileyo zisetyenziswa rheology modifiers ziquka:

I-Cellulose Derivatives:
Iselulosi yeHydroxyethyl (HEC)
Iselulosi yeHydroxypropyl (HPC)
I-Methyl cellulose (MC)
I-Ethyl hydroxyethyl cellulose (EHEC)
Ii-Associative Thickeners:
I-Hydrophobically modified ethoxylated urethane (HEUR)
I-emulsion enyibilikayo yealkali eguqulwe ngeHydrophobically (HASE)
Iselulosi ye-hydroxyethyl eguqulwe nge-Hydrophobically (HMHEC)
Izinto eziphuma kwi-Polyacrylic Acid:
Carbomer
Acrylic acid copolymers
Udongwe lweBentonite:
Udongwe lweBentonite lutyebe lwendalo oluphuma kuthuthu lwentaba-mlilo. Isebenza ngokwenza uthungelwano lwamasuntswana abamba iimolekyuli zamanzi, ngaloo ndlela ijiya ipeyinti.
Ijeli yeSilica:
Ijeli ye-silica yi-thickener yokwenziwa esebenza ngokufunxa kwaye ibambe ulwelo ngaphakathi kwesakhiwo sayo esinemingxuma, ngaloo ndlela ijiya ipeyinti.
I-Polyurethane Thickeners:
I-polyurethane thickeners zipolima zokwenziwa ezinokuthi zilungelelaniswe ukubonelela ngeempawu ezithile ze-rheological kwipeyinti.
Xanthan Gum:
I-Xanthan gum sisityebi sendalo esiphuma ekuvundisweni kweswekile. Yenza ukuqina okufana nejeli xa ixutywe namanzi, iyenza ilungele ukujiya kwepeyinti.
Ezi zilungiso ze-rheology zongezwa ngokuqhelekileyo ekuqulunqweni kwepeyinti ngexesha lenkqubo yokuvelisa ngobuninzi obuchanekileyo ukufezekisa i-viscosity efunwayo kunye neempawu zokuhamba. Ukukhetha i-thickener kuxhomekeke kwizinto ezahlukeneyo ezifana nohlobo lwepeyinti (umzekelo, i-water-based okanye i-solvent-based), i-viscosity efunwayo, indlela yesicelo, kunye nokuqwalaselwa kokusingqongileyo.

Ukongeza ekuqiniseni ipeyinti, izilungisi zerheology zikwadlala indima ebalulekileyo ekuthinteleni ukuthoba, ukuphucula ukuxubha, ukunyusa umgangatho, kunye nokulawula ukutshiza ngexesha lokufaka isicelo. ukhetho lwe-thickener luyimfuneko ekunqumeni ukusebenza ngokubanzi kunye neempawu zesicelo sepeyinti.
