Ke mofuta ofe oa "thickener" o sebelisoang ho penta?

The thickener e sebelisoang pente hangata ke ntho e eketsang viscosity kapa botenya ba pente ntle le ho ama thepa ea eona e meng e kang 'mala kapa nako ea ho omisa. E 'ngoe ea mefuta e tloaelehileng ea "thickener" e sebelisoang penteng ke rheology modifier. Liphetoho tsena li sebetsa ka ho fetola mokhoa oa ho phalla ha pente, ho etsa hore e be e teteaneng le e tsitsitseng haholoanyane.

Ho na le mefuta e 'maloa ea liphetoho tsa rheology tse sebelisoang ha ho etsoa pente, e' ngoe le e 'ngoe e na le thepa le melemo ea eona e ikhethang. Tse ling tsa li-addifi tsa rheology tse sebelisoang haholo li kenyelletsa:

Lintho tse tsoang ho Cellulose:
Hydroxyethyl cellulose (HEC)
Hydroxypropyl cellulose (HPC)
Methyl cellulose (MC)
Ethyl hydroxyethyl cellulose (EHEC)
Li-Asociative Thickeners:
Hydrophobically modified ethoxylated urethane (HEUR)
Hydrophobically modified alkali-soluble emulsion (HASE)
Hydrophobically modified hydroxyethyl cellulose (HMHEC)
Lintho tse tsoang ho polyacrylic acid:
Carbomer
Acrylic acid copolymers
Bentonite Clay:
Letsopa la Bentonite ke motenya oa tlhaho o tsoang moloreng oa seretse se chesang. E sebetsa ka ho etsa marang-rang a likaroloana tse tšoarang limolek'hule tsa metsi, kahoo li tiisa pente.
Gel ea silika:
Silica gel ke setenya sa maiketsetso se sebetsang ka ho monya le ho ts'oara mokelikeli ka har'a sebopeho sa eona se nang le masoba, kahoo se tiisa pente.
Lisebelisoa tsa polyurethane:
Polyurethane thickeners ke li-polymer tsa maiketsetso tse ka etsoang ho fana ka thepa e khethehileng ea rheological penteng.
Xanthan Gum:
Xanthan gum ke motenya oa tlhaho o tsoang ho belisoa ha tsoekere. E etsa sebopeho se kang gel ha se kopane le metsi, se etsa hore se tšoanelehe bakeng sa pente e teteaneng.
Liphetoho tsena tsa rheology li atisa ho eketsoa ka mokhoa oa ho penta nakong ea ts'ebetso ea tlhahiso ka bongata bo nepahetseng ho finyella viscosity e lakatsehang le thepa ea phallo. Khetho ea "thickener" e ipapisitse le lintlha tse fapaneng tse kang mofuta oa pente (mohlala, e thehiloeng metsing kapa e thehiloeng ho solvent), viscosity e lakatsehang, mokhoa oa ts'ebeliso, le lintlha tsa tikoloho.

Ntle le ho tenya pente, li-modifiers tsa rheology li boetse li bapala karolo ea bohlokoa ho thibela ho putlama, ho ntlafatsa brushability, ho matlafatsa boemo, le ho laola ho hasana ha metsi nakong ea kopo. khetho ea thickener ke ea bohlokoa ho khetholla ka kakaretso tshebetso le litšobotsi tsa kopo ea pente.
