Hlobo luni lwesithambisi esisetshenziswa kupende?

Isithambisi esisetshenziswa kupende ngokuvamile siyinto ekhulisa ukujiya noma ukujiya kopende ngaphandle kokuthinta ezinye izici zalo njengombala noma isikhathi sokoma. Enye yezinhlobo ezivame kakhulu zesithambisi esisetshenziswa kupende isithambisi se-rheology. Lezi zithambisi zisebenza ngokushintsha indlela opheka ngayo upende, okwenza ube mkhulu futhi uzinze kakhudlwana.

Kunezinhlobo eziningana ze-rheology modifier ezisetshenziswa ekwakhiweni kopende, ngayinye inezakhiwo zayo ezihlukile kanye nezinzuzo. Ezinye ze-rheology modifier ezisetshenziswa kakhulu zifaka:

Izinto Ezivela Ku-Cellulose:
I-Hydroxyethyl cellulose (HEC)
I-Hydroxypropyl cellulose (HPC)
I-Methyl cellulose (MC)
I-Ethyl hydroxyethyl cellulose (EHEC)
Izithinti Ezihlangene:
I-urethane e-ethoxylated eguqulwe nge-hydrophobically (HEUR)
I-emulsion ye-alkali-soluble eguquliwe emanzini (i-HASE)
I-hydroxyethyl cellulose eguquliwe ngamanzi (i-HMHEC)
Izinto ezisuselwa ku-Polyacrylic Acid:
I-Carbomer
Ama-copolymer e-acrylic acid
Ubumba lwe-Bentonite:
Ubumba lwe-Bentonite luyisithako semvelo esitholakala emlotheni wentaba-mlilo. Lusebenza ngokwakha inethiwekhi yezinhlayiya ezibamba ama-molecule amanzi, ngaleyo ndlela lujiyise upende.
Ijeli yeSilica:
Ijeli le-silica liyisithako sokwenziwa esisebenza ngokumunca nokubamba uketshezi ngaphakathi kwesakhiwo salo esinezimbobo, ngaleyo ndlela siqinise upende.
Izinto Zokuqina zePolyurethane:
Ama-polyurethane thickeners angama-polymers okwenziwa angalungiswa ukuze anikeze izakhiwo ezithile ze-rheological kupende.
I-Xanthan Gum:
I-Xanthan gum iyisithako semvelo esitholakala ekuvuthweni koshukela. Yakha ukuqina okufana nejeli uma ixutshwe namanzi, okwenza ifanelekele ukupenda okujiyile.
Lezi ziguquli ze-rheology zivame ukungezwa ekwakhiweni kopende ngesikhathi senqubo yokukhiqiza ngobuningi obuqondile ukuze kufezwe i-viscosity efiselekayo kanye nezakhiwo zokugeleza. Ukukhetha i-thickener kuncike ezintweni ezahlukahlukene njengohlobo lopende (isb., olusekelwe emanzini noma olusekelwe ku-solvent), i-viscosity efiselekayo, indlela yokusebenzisa, kanye nokucatshangelwa kwemvelo.

Ngaphezu kokuqinisa upende, ama-rheology modifier nawo adlala indima ebalulekile ekuvimbeleni ukugoba, ukuthuthukisa ukuxubha, ukuthuthukisa ukulingana, kanye nokulawula ukuchitheka ngesikhathi sokufaka. Ukukhetha i-thickener kubalulekile ekunqumeni ukusebenza okuphelele kanye nezici zokusetshenziswa kopende.
