Kedu ụdị thickener a na-eji agba?

Ihe a na-eji agba agba na-abụkarị ihe na-abawanye viscosity ma ọ bụ ọkpụrụkpụ nke agba na-emetụtaghị ihe ndị ọzọ dị ka agba ma ọ bụ oge ihicha. Otu n'ime ụdị thickener a na-ejikarị eme ihe na agba bụ rheology modifier. Ndị na-eme mgbanwe ndị a na-arụ ọrụ site n'ịgbanwe omume na-agba agba nke agba, na-eme ka ọ dịkwuo ụba ma kwụsie ike.

Enwere ọtụtụ ụdị rheology modifiers ejiri mee ihe n'ụdị agba, nke ọ bụla nwere ihe pụrụ iche na uru ya. Ụfọdụ n'ime mgbanwe rheology a na-ejikarị eme ihe gụnyere:

Ihe nrụpụta cellulose:
Hydroxyethyl cellulose (HEC)
Hydroxypropyl cellulose (HPC)
Methyl cellulose (MC)
Ethyl hydroxyethyl cellulose (EHEC)
Mkpakọrịta Thickers:
Ọkpụkpụ urethane ethoxylated emegharịrị (HEUR)
Emulsion alkali soluble gbanwetụrụ hydrophobically (HASE)
Hydroxyethyl cellulose (HMHEC) gbanwere nke hydrophobically
Ihe mejupụtara polyacrylic acid:
Carbomer
Acrylic acid copolymers
Bentonite Clay:
Ụrọ Bentonite bụ ụrọ ebumpụta ụwa sitere na ntụ mgbawa ugwu. Ọ na-arụ ọrụ site n'ịmepụta netwọk nke ụmụ irighiri ihe na-ejide ụmụ irighiri mmiri, si otú a na-eme ka agba ahụ sie ike.
Gel silica:
Silica gel bụ ihe na-emepụta ihe na-arụ ọrụ site na ịmịnye na ọnyà mmiri n'ime ihe owuwu ya, si otú a na-eme ka agba ahụ sie ike.
Ihe mkpuchi polyurethane:
Polyurethane thickeners bụ sịntetik polymers nke nwere ike ahaziri iji nye kpọmkwem rheological Njirimara na agba.
Xanthan chịngọm:
Xanthan chịngọm bụ ihe na-esi ísì ụtọ sitere na gbaa ụka shuga. Ọ na-emepụta ihe dị ka gel mgbe a na-ejikọta ya na mmiri, na-eme ka ọ dị mma maka agba agba.
A na-agbakwunyekarị ndị na-eme mgbanwe rheology ndị a n'ụdị agba n'oge a na-emepụta ihe n'ụzọ ziri ezi iji nweta viscosity na ihe ndị na-asọpụta chọrọ. Nhọrọ nke thickener na-adabere n'ụdị dị iche iche dị ka ụdị agba (dịka ọmụmaatụ, mmiri na-adabere na mmiri ma ọ bụ ihe mgbaze), viscosity chọrọ, usoro ntinye, na echiche gburugburu ebe obibi.

Na mgbakwunye na ịgbatị agba ahụ, ndị na-emegharị rheology na-ekerekwa òkè dị mkpa n'ịgbochi ịla n'iyi, imeziwanye brushability, ịkwalite ọkwa, na ịchịkwa mgbasa ozi n'oge ngwa. nhọrọ nke thickener dị mkpa n'ịchọpụta ọrụ zuru oke na njirimara ngwa nke agba.
