Rudzii rwechinogodza chinoshandiswa mupendi?

Chinhu chinogodza chinoshandiswa mupendi chinowanzova chinhu chinowedzera kukora kana kuti kukora kwependi pasina kukanganisa zvimwe zvinhu zvayo zvakaita seruvara kana nguva yekuoma. Imwe yemhando dzinonyanya kushandiswa mupendi i rheology modifier. Izvi zvinogodza zvinoshandura mafambiro ependi, zvichiita kuti iite gobvu uye igare yakasimba.

Kune mhando dzakasiyana dze rheology modifiers dzinoshandiswa mukugadzira pendi, imwe neimwe ine hunhu hwayo hwakasiyana uye zvakanakira. Mamwe e rheology modifiers anonyanya kushandiswa anosanganisira:

Zvinobva muCellulose:
Hydroxyethyl cellulose (HEC)
Hydroxypropyl cellulose (HPC)
Methyl cellulose (MC)
Ethyl hydroxyethyl cellulose (EHEC)
Zvishongedzo Zvinobatanidza:
Urethane inogadziriswa nehydrophobically ethoxylated urethane (HEUR)
Musanganiswa wealkali-soluble emulsion (HASE) unogadziriswa nehydrophobically (hydrophobically)
Hydroxyethyl cellulose yakagadziriswa nehydrophobically (HMHEC)
Zvibereko zvePolyacrylic acid:
Carbomer
Makopiyuta eAcrylic acid
Ivhu reBentonite:
Ivhu reBentonite chinhu chinogokora chinobva mudota rekuputika kwemakomo. Rinoshanda nekugadzira network yezvimedu zvinobata mamorekuru emvura, nokudaro zvichiita kuti pendi iome.
Gel reSilica:
Silica gel chinhu chinosimbisa ganda chinoshanda nekupinza nekubata mvura mukati mechimiro chayo chine maburi, nokudaro zvichiita kuti pendi ikure.
Zvinhu Zvinosimbisa Polyurethane:
Zvishongedzo zvepolyurethane mapolymer akagadzirwa anogona kugadzirwa kuti ape pendi hunhu hwakananga hwerheological.
Xanthan Gum:
Xanthan gum chinhu chinokora chinobva mukuvirisa shuga. Chinoumba chimiro chakafanana nejeli kana chikasanganiswa nemvura, zvichiita kuti chikodzere pendi inokora.
Izvi zvinogadzirisa rheology zvinowanzowedzerwa mukugadzirwa kwependi panguva yekugadzira muhuwandu hwakakodzera kuti pave nekupenya kwaunoda uye hunhu hwekuyerera. Sarudzo yechinhu chinogodza zvinoenderana nezvinhu zvakasiyana-siyana zvakaita serudzi rwependi (semuenzaniso, inobva mumvura kana kuti inobva muzvinyungudutsi), kupenya kwaunoda, nzira yekushandisa, uye kufunga nezvezvakatipoteredza.

Pamusoro pekukora pendi, rheology modifiers inoitawo basa rakakosha mukudzivirira kudzika, kunatsiridza kukwesha, kuwedzera kuenzana, uye kudzora kupararira kwayo panguva yekuisa pendi. Kusarudza thickener kwakakosha pakuona mashandiro ese uye hunhu hwekushandisa pendi.
