Ke mofuta ofe oa setlolo se teteaneng se sebelisoang penteng?

Sethibisi se sebelisoang penteng hangata ke ntho e eketsang viscosity kapa botenya ba pente ntle le ho ama litšobotsi tsa eona tse ling tse kang 'mala kapa nako ea ho oma. E 'ngoe ea mefuta e tloaelehileng ea sethibisi se sebelisoang penteng ke rheology modifier. Lithibisi tsena li sebetsa ka ho fetola boitšoaro ba phallo ea pente, e leng se etsang hore e be teteaneng le e tsitsitseng haholoanyane.

Ho na le mefuta e 'maloa ea li-modifiers tsa rheology tse sebelisoang mefuteng ea pente, e 'ngoe le e 'ngoe e na le litšobotsi le melemo ea eona e ikhethang. Tse ling tsa li-modifiers tsa rheology tse sebelisoang haholo li kenyelletsa:

Li-derivative tsa Cellulose:
Hydroxyethyl cellulose (HEC)
Hydroxypropyl cellulose (HPC)
Selulose ea Methyl (MC)
Ethyl hydroxyethyl cellulose (EHEC)
Li-Thickeners tse Kopanetsoeng:
Urethane e fetotsweng ka mokhoa oa hydrophobically e nang le ethoxylated urethane (HEUR)
Emulsion e qhibilihang ka alkali e fetotsoeng ka metsi (HASE)
Hydroxyethyl cellulose e fetotsoeng ka hydrophobically (HMHEC)
Li-derivative tsa asiti ea polyacrylic:
Carbomer
Li-copolymer tsa asiti ea acrylic
Letsopa la Bentonite:
Letsopa la Bentonite ke ntho e tenyang ya tlhaho e tswang moloreng wa seretse se chesang. Le sebetsa ka ho etsa marangrang a dikarolwana tse tshwarang dimolek'hule tsa metsi, ka hona le teteanya pente.
Gel ea Silika:
Gel ea silica ke setei sa maiketsetso se sebetsang ka ho monya le ho tšoara metsi ka har'a sebopeho sa eona se nang le masoba, ka hona se tebisa pente.
Li-Thickeners tsa Polyurethane:
Li-thickeners tsa polyurethane ke li-polymer tsa maiketsetso tse ka etselitsoeng ho fana ka thepa e itseng ea rheological penteng.
Xanthan Gum:
Xanthan gum ke setenya sa tlhaho se tswang ho bediseng ha tswekere. E etsa sebopeho se tshwanang le sa gel ha e kopantswe le metsi, e leng se etsang hore e lokele pente e tenyang.
Hangata diphetoho tsena tsa rheology di eketswa mofuteng wa pente nakong ya tshebetso ya tlhahiso ka bongata bo nepahetseng ho fihlella viscosity le dibopeho tse lakatsehang tsa phallo. Kgetho ya setenya e itshetlehile ka mabaka a fapaneng a kang mofuta wa pente (mohlala, e thehilweng metsing kapa e thehilweng ho solvent), viscosity e lakatsehang, mokgwa wa tshebediso, le dintho tse amehang tikolohong.

Ntle le ho tebisa pente, diphetoho tsa rheology le tsona di bapala karolo ya bohlokwa ho thibeleng ho thekesela, ho ntlafatsa ho kgarajwa ha pente, ho ntlafatsa ho leka-lekana ha pente, le ho laola ho fafatsa ha pente nakong ya ho e sebedisa. kgetho ya sethibisi e bohlokwa ho fumana tshebetso yohle le dibopeho tsa tshebediso ya pente.
