Uhlobo luni lwe-thickener olusetshenziswa kupende?

I-thickener esetshenziswa kupende ngokuvamile iyinto ekhulisa i-viscosity noma ukujiya kopende ngaphandle kokuthinta ezinye izici zayo njengombala noma isikhathi sokumisa. Enye yezinhlobo ezivame kakhulu ze-thickener ezisetshenziswa ngopende i-rheology modifier. Lezi zilungisi zisebenza ngokushintsha indlela yokugeleza kapende, ziwenze ube mkhulu futhi uzinze.

Kunezinhlobo eziningana ze-rheology modifiers ezisetshenziswa ekwenziweni kwepende, ngayinye inezindawo zayo eziyingqayizivele kanye nezinzuzo. Ezinye ze-rheology modifiers ezisetshenziswa kakhulu zihlanganisa:

I-Cellulose Derivatives:
I-Hydroxyethyl cellulose (HEC)
I-Hydroxypropyl cellulose (HPC)
I-Methyl cellulose (MC)
I-Ethyl hydroxyethyl cellulose (EHEC)
Ama-Associative Thickeners:
I-Hydrophobically modified ethoxylated urethane (HEUR)
I-emulsion encibilikayo ye-alkali eguqulwe nge-Hydrophobically (HASE)
I-hydroxyethyl cellulose (HMHEC) eguqulelwe nge-Hydrophobically
Izithako ze-Polyacrylic Acid:
I-Carbomer
Acrylic acid copolymers
I-Bentonite Clay:
Ubumba be-Bentonite luwugqinsi lwemvelo olutholakala kumlotha wentaba-mlilo. Isebenza ngokwakha inethiwekhi yezinhlayiya ezibamba ama-molecule amanzi, ngaleyo ndlela iqinise upende.
I-silica Gel:
Ijeli ye-silica iyi-thickener yokwenziwa esebenza ngokumunca futhi ibambe uketshezi ngaphakathi kwesakhiwo sayo esinezimbotshana, ngaleyo ndlela ijiye upende.
I-Polyurethane Thickeners:
Ama-polyurethane thickeners angama-polymers okwenziwa angalungiswa ukuze anikeze izici ezithile ze-rheological kupende.
I-Xanthan Gum:
I-Xanthan gum iwugqinsi wemvelo osuselwa ekuvutshelweni kukashukela. Yakha ukufana okufana nejeli uma ixubene namanzi, okwenza ifaneleke upende oqina.
Lezi ziguquli ze-rheology zivame ukungezwa ekwakhiweni kwepende phakathi nenqubo yokukhiqiza ngamanani anembile ukuze kuzuzwe i-viscosity oyifunayo kanye nezakhiwo zokugeleza. Ukukhethwa kwe-thickener kuncike ezicini ezihlukahlukene ezifana nohlobo lukapende (isb, olususelwe emanzini noma olusekelwe ku-solvent), i-viscosity oyifunayo, indlela yokufaka isicelo, nokucatshangelwa kwemvelo.

Ngaphezu kokuqinisa upende, izilungisi ze-rheology nazo zidlala indima ebalulekile ekuvimbeleni ukuwohloka, ukuthuthukisa ukuxubha, ukwenza ngcono izinga, nokulawula ukuchaphazeka phakathi nokufakwa. ukukhethwa kwe-thickener kubalulekile ekunqumeni ukusebenza okuphelele kanye nezici zokusetshenziswa kopende.
