Ndeupi rudzi rwehutsi hunoshandiswa mupende?

Iyo thickener inoshandiswa mupende inowanzova chinhu chinowedzera viscosity kana kukora kwepende pasina kukanganisa zvimwe zvayo zvakadai seruvara kana nguva yekuoma. Imwe yemhando dzinowanzozivikanwa dzekukora inoshandiswa mupende ndeye rheology modifier. Aya magadzirirwo anoshanda nekushandura mafambiro ekuyerera kwepende, ichiita kuti ive gobvu uye igadzikane.

Kune akatiwandei emhando dzerheology modifiers dzinoshandiswa mukugadzira pendi, imwe neimwe iine yayo yakasarudzika zvimiro uye zvakanakira. Mamwe eanonyanya kushandiswa rheology modifiers anosanganisira:

Cellulose Derivatives:
Hydroxyethyl cellulose (HEC)
Hydroxypropyl cellulose (HPC)
Methyl cellulose (MC)
Ethyl hydroxyethyl cellulose (EHEC)
Associative Thickeners:
Hydrophobically modified ethoxylated urethane (HEUR)
Hydrophobically modified alkali-soluble emulsion (HASE)
Hydrophobically modified hydroxyethyl cellulose (HMHEC)
Polyacrylic Acid Derivatives:
Carbomer
Acrylic acid copolymers
Bentonite Clay:
Bentonite ivhu ndeyechisikigo thickener inotorwa kubva kune inoputika dota. Inoshanda nekugadzira network yezvimedu zvinoteya mamorekuru emvura, zvichibva zvawedzera pendi.
Silica Gel:
Silica gel is a synthetic thickener iyo inoshanda nekukweva uye kuteya mvura mukati meiyo porous chimiro, nokudaro ichikobvura pendi.
Polyurethane Thickeners:
Polyurethane thickeners ma polymers ekugadzira anogona kugadzirwa kuti ape chaiwo rheological zvimiro kune pendi.
Xanthan Gum:
Xanthan chingamu chikobvu chechisikigo chinobva pakuviriswa kweshuga. Inoumba gel-kufanana kuwirirana kana yakasanganiswa nemvura, ichiita kuti ive yakakodzera pende yekukora.
Aya ma rheology modifiers anowanzo kuwedzerwa kune pendi yekugadzira panguva yekugadzira muhuwandu chaihwo kuti uwane inodiwa viscosity uye kuyerera zvivakwa. Sarudzo yekukora inoenderana nezvinhu zvakasiyana serudzi rwependi (semuenzaniso, mvura-yakavakirwa kana yakanyungudika-yakavakirwa), viscosity inodiwa, nzira yekushandisa, uye kufunga kwezvakatipoteredza.

Pamusoro pekukora pendi, rheology modifiers inoitawo basa rakakosha mukudzivirira kusagika, kunatsiridza brashi, kukwidziridza kuenzana, uye kudzora kusasa panguva yekushandisa. kusarudzwa kwe thickener kwakakosha pakusarudza kushanda kwese uye kushandiswa kwemaitiro epende.
