Liquid detergents imhando yakajairika yechigadzirwa chinoshandiswa mukuchenesa imba. Ivo vane mvura-yakavakirwa uye vanogona kunyatsobvisa tsvina, girisi uye kumwe kusvibiswa. Kuti vavandudze ruzivo rwavo rwekushandisa, vanowanzoda kugadziriswa kune viscosity yakakodzera. Iyo viscosity ye detergent haifaniri kunge yakaderera, kana zvisina kudaro ichayerera nokukurumidza, zvichiita kuti zvive zvakaoma kudzora huwandu, uye inonzwa "yakaonda" kana yakashandiswa; asi haifaniri kunge yakanyanyisa kukwirira, sezvo inogona kunge yakanyanyisa uye yakaoma kugovera nekuchenesa. Mathickeners saka ave chimwe chezvakakosha zvinongedzo mune yemvura detergent magadzirirwo.
1. Sodium carboxymethyl cellulose (CMC)
Sodium carboxymethyl cellulose chikobvu chinoshandiswa zvakanyanya mu detergents. Iyo inonyungudika nemvura inonyungudika selulosi inobuda iyo inogona zvinobudirira kuwedzera viscosity yezvinwiwa. CMC ine zvinotevera zvakanakira:
Yakanaka kunyungudika kwemvura: CMC inogona kunyungudika nekukurumidza mumvura uye kugadzira yunifomu, yakajeka mhinduro mune ine aqueous mhinduro.
Yakapfava uye isingatsamwise: CMC ndeye yakasikwa polymer zvinhu izvo zvisina zvinokuvadza paganda kana nharaunda, zvichisangana nezvinodiwa nevatengi vemazuva ano kuchengetedza kwezvakatipoteredza uye hutano.
Kugarisana kwakanaka: CMC inonyatso kuenderana nezvimwe zvinongedzo mune detergent mafomula, pasina matambudziko senge stratification kana kuora, uye haizokanganisa kugeza maitiro.
2. Xanthan chingamu
Xanthan chingamu ndeye yakasikwa polysaccharide komboni inogadzirwa nekuvirisa kwebhakitiriya, inowanzoshandiswa muchikafu, zvizorwa uye zvekugezesa. Iko kushandiswa kwexanthan gum mune detergents kune zvinotevera maitiro:
Yakanakisa thickening maitiro: Kunyangwe pachiyero chakaderera chekuwedzera, xanthan chingamu inogona kuwedzera zvakanyanya viscosity yemvura.
Anti-shear dilution performance: Xanthan gum ine yakanaka shear dilution zvivakwa. Kana yamutswa kana kudzvinyirirwa, viscosity ye detergent ichaderera kwechinguva, iyo iri nyore kugovera uye kushandiswa; asi iyo viscosity inogona kukurumidza kudzoserwa mushure mekushandisa kudzivirira yakawandisa fluidity.
Yakasimba tembiricha kuramba: Xanthan chingamu inogona kuramba yakatsiga pakakwirira kana kuderera tembiricha, haiwanzo kuderedzwa kana kudzikisa viscosity, uye inokora iyo ichiri kuita zvakanaka pasi pemamiriro akanyanya.
3. Polyacrylate thickeners
Polyacrylate thickeners (zvakadai seCarbomer) zvinhu zvepolymer zvekugadzira zvine simba rekukora zvakanyanya, kunyanya akakodzera kukora zvinogezesa zvinoonekera. Zvikuru zvayo zvinosanganisira:
Kujeka kwepamusoro: Polyacrylate inogona kuumba mhinduro dzakajeka, zvichiita kuti ive yakanakira gobvu sarudzo yezvinosuka zvinoonekera.
Kunyatsoita gobvu kugona: Polyacrylate inogona kuwana yakakura kukora mhedzisiro pakadzika yakadzika uye ine chaiyo kutonga pamusoro pe viscosity.
pH kutsamira: Iko kukora mhedzisiro yeiyi thickener ine hukama nepH kukosha kwemhinduro, uye inowanzoita zvakanyanya pasi pemamiriro asina simba ealkaline, saka iyo pH yeformula inoda kugadziridzwa kana ichishandiswa kuwana yakanyanya kunaka.
4. Munyu wakakora
Minyu (yakadai sesodium chloride, sodium sulfate, nezvimwewo) inowanzoita makobvu mumidziyo yekuchenesa mvura, kunyanya mumigero ine surfactants. Nheyo yayo yekushanda ndeye kushandura kurongeka kwema surfactant molecules nekugadzirisa iyo ionic simba rehurongwa, nekudaro ichikanganisa viscosity. Zvakanakira zvekukora munyu zvinosanganisira:
Mutengo wakaderera: Zvipfuyo zvemunyu zvakachipa uye zviri nyore kuwana, saka zvine mutengo wakanaka mukugadzirwa kwehuwandu.
Synergistic mhedzisiro ine ma surfactants: Munyu wakakora unogona kunyatso kusimudzira viscosity ye system mumaformula ane yakakwira surfactant yemukati.
Yakasiyana-siyana yekushandiswa: Iyi nzira yekukora inoshandiswa mune zvakawanda zvekutengesa detergents, kunyanya mumaindasitiri ekugezesa.
Nekudaro, kushandiswa kwemafuta emunyu kunewo zvimwe zvinogumira. Semuenzaniso, iyo mari yakawedzerwa haifanirwe kunge yakawandisa, zvikasadaro inogona kukonzera kunyungudika kwe detergent kuderera kana kutonaya. Mukuwedzera, iyo viscosity inogadzirisa kurongeka kwemunyu thickeners haina kunaka semamwe thickeners.
5. Ethoxylated fatty alcohols (yakadai se sodium C12-14 doro ether sulfate)
Pamusoro peiyo huru yekuchenesa basa, ethoxylated fatty alcohol surfactants zvakare ine imwe thickening maitiro. Nekugadzirisa chiyero cheaya ma surfactants, imwe thickening mhedzisiro inogona kuwanikwa. Zvayakanakira ndezvekuti:
Versatility: Iyi mhando ye surfactant haingoite basa rekukora chete, asi zvakare inosimudzira detergency ye detergents.
Kuenderana kwakanaka nezvimwe zvinongedzo: Ethoxylated mafuta madoro anowirirana neakajairika surfactants, flavour, pigment uye zvimwe zvinongedzo, uye hazvizokanganisa kuita kwechigadzirwa chekupedzisira.
Deredza kudiwa kwezvimwe zvinokora: Sezvo zviine zvese zvekuchenesa uye kukora mabasa, kushandiswa kweakachena thickeners kunogona kudzikiswa mufomula, nekudaro optimize mitengo.
6. Acrylate copolymers
Acrylate copolymers ikirasi yeanogadzira polymer thickeners ayo anowanzo shandiswa mumhando yepamusoro-yekupedzisira kana yakakosha-basa rekugezesa. Zvimiro zvavo zvikuru zvinosanganisira:
Chaiyo viscosity control: Nekugadzirisa chimiro checopolymer, viscosity yechigadzirwa inogona kunyatsodzorwa kuti iwane mhedzisiro yaunoda.
Kugadzikana kwakanaka: Iyi thickener ine yakanaka makemikari uye kugadzikana kwemuviri uye inogona kuchengetedza yakanaka viscosity mukupisa kwakasiyana, pH kukosha uye surfactant masisitimu.
Haisi nyore kudonhedza: Acrylate copolymer thickeners inoratidza yakanaka anti-delamination kugona mune yemvura yekugezesa, kuve nechokwadi kugadzikana kwechigadzirwa mukuchengetedza kwenguva refu.
Sarudzo yekukora mumidziyo yekugezesa yemvura inoenderana nezvakawanda zvinhu, zvinosanganisira rudzi rwesurfactant mune fomula, pachena zvinodiwa, mutengo wekudzora uye ruzivo rwemushandisi. Sodium carboxymethyl cellulose uye xanthan chingamu kazhinji isarudzo dzakakodzera mumigero yemumba yakajairwa nekuda kwekunyungudika kwayo kwemvura, hunyoro uye kukora. Kune ma detergents akajeka, polyacrylate thickeners inosarudzwa. Munyu wakakora une zvakanakira mutengo uye wakakodzera kugadzirwa kwakakura kwezvigadzirwa zvemaindasitiri.
