Kuwedzerahydroxypropyl methylcellulose (HPMC)kune zvigetsi zvemvura zvinoda matanho uye maitiro ekuona kuti inogona kunyungudika zvizere uye kuita basa mukukora, kudzikamisa nekuvandudza rheology.
1. Basic maitiro uye mabasa eHPMC
Hunhu hweHPMC
HPMC isiri-ionic cellulose ether ine yakanaka solubility, thickening uye kugadzikana. Inogona kuumba yakajeka colloidal mhinduro mune aqueous system uye ine yakasimba kuchinjika kune shanduko yekushisa uye pH.
Basa mumidziyo yekuchenesa mvura
Kukora mhedzisiro: Ipa yakakodzera viscosity uye uvandudze kunzwa kwe detergents.
Kunatsiridza kugadzikana: Dzivirira detergent stratification kana kunaya kwemvura.
Rheology kugadzirisa: Ipa mvura yekugezesa yakanaka fluidity uye kugona kumiswa.
Kuvandudza ruzivo rwemushandisi: Wedzera kugadzikana uye kunamatira kwefuro.
2. Matanho ekutanga ekuwedzera HPMC
Kugadzirira
Sarudzo: Sarudza yakakodzera HPMC modhi (senge viscosity giredhi, dhigirii rekutsiva, nezvimwewo) zvinoenderana nezvinodiwa zvechigadzirwa. Yakajairika mhando dzinosanganisira yakaderera viscosity uye yakakwirira viscosity HPMC kune akasiyana thickening mhedzisiro.
Kuyera: Nyatsoyera iyo inodiwa HPMC zvinoenderana nezvinodiwa fomula.
Pre-kuparadzira HPMC
Kusarudzwa kweMedia: Pre-dispersa HPMC nemvura inotonhora kana imwe isina-solvent media (yakadai se ethanol) kudzivirira kuumbwa kwemapundu kana yawedzerwa zvakananga.
Kuwedzera nzira: Zvishoma nezvishoma nyudza HPMC mumvura inotonhora yakamutswa kudzivirira kuungana.
Kukurudzira maitiro: Ramba uchikurudzira kweanenge 10-15 maminetsi kusvikira kupararira kweyunifomu kwaumbwa.
Dissolution matanho
Heating activation: Kupisa kupararira kune 40-70 ℃ kukurudzira kuzvimba uye kuparara kweHPMC. Izvo zvinofanirwa kucherechedzwa kuti kupisa kwekushisa kweHPMC yemhando dzakasiyana kwakasiyana zvishoma.
Kukurudzira nekunyunguduka: Paunenge uchipisa, ramba uchimhanyisa nekumhanya kwepakati kusvika HPMC yanyungudika kuita mvura inoonekera kana yemukaka yunifomu.
Kusanganisa ne liquid detergent base liquid
Kutonhodza kurapwa: Cool theHPMCmhinduro kune tembiricha yekamuri kudzivirira kufurira kwekushisa kwakanyanya pane zvimwe zvinoshanda zve detergent.
Kuwedzera zvishoma nezvishoma: Zvishoma nezvishoma wedzera iyo HPMC mhinduro kune yemvura detergent base fluid uchikurudzira kuti uve nechokwadi chekugovera yunifomu.
Viscosity gadziriso: Gadzirisa huwandu hweHPMC mhinduro kuti uwane iyo inodiwa viscosity.
3. Chengetedzo
Dzivisa agglomeration
Kana uchiwedzera HPMC, mwaya zvishoma nezvishoma uye kurunga zvakaenzanirana, zvikasadaro zviri nyore kuumba agglomerates, zvichikonzera kuparara kusina kukwana.
Pre-dispersion inhanho yakakosha, uye kushandiswa kwemvura inotonhora kana imwe isina-kunyungudika midhiya inogona kudzivirira zvinobudirira agglomeration.
Kukurudzira nzira
Shandisa zvepakati-kumhanyisa kubvongodza kudzivirira mabubbles anokonzerwa nekukasira kubvongodza, izvo zvinokanganisa kutaridzika kwemhando yemvura yekugezesa.
Kana zvichikwanisika, shandisa midziyo yekugera yakakwirira kuti uvandudze kushanda zvakanaka kwekuparadzira.
Kudzora tembiricha
HPMC inonzwa tembiricha, uye tembiricha yakanyanyisa kana yakaderera inogona kukonzera kuparara kwakashata kana kurasikirwa nebasa. Naizvozvo, tembiricha inofanira kunyatsodzorwa panguva yekuparara.
Kuenderana nezvimwe zvinhu
Tarisa kuenderana kweHPMC nezvimwe zvinongedzo mudetergent, kunyanya nzvimbo yemunyu yakakwira inogona kukanganisa kukora kweHPMC.
Nezve detergent formulas ine akasimba asidhi kana alkali akasimba, kugadzikana kweHPMC kunofanirwa kuve nechokwadi.
Dissolution nguva
Zvinotora imwe nguva yenguva kuti HPMC iparare zvachose, uye inofanira kumutswa nemoyo murefu kudzivirira viscosity kusagadzikana nekuda kwekuparara kusina kukwana.
4. Matambudziko akajairika uye mhinduro
Dissolution matambudziko
Chikonzero: HPMC inogona kunge yakasanganiswa kana tembiricha yekumisa haina kufanira.
Solution: Optimize pre-kupararira danho uye zvakasimba kudzora kudziyisa uye inomutsa maitiro.
Detergent stratification kana kunaya kwemvura
Chikonzero: Kusakwana HPMC yekuwedzera kana kusakwana kupera.
Solution: Wedzera huwandu hweHPMC zvakakodzera uye simbisa kuparara kwakazara.
High viscosity
Chikonzero: Yakawandisa HPMC inowedzerwa kana isina kusanganiswa.
Solution: Zvakakodzera kuderedza kuwanda kwekuwedzera uye kuwedzera nguva yekukurudzira.
KuwedzeraHPMCto liquid detergents inzira inoda kutonga kwakanaka. Kubva pakusarudza iyo yakakodzera HPMC modhi kusvika kukwenenzvera kunyungudika uye kusanganisa matanho, nhanho imwe neimwe ine kukosha kwakakosha pakuita kwechigadzirwa chekupedzisira. Kuburikidza nekushanda chaiko, kukora, kudzikamisa uye rheology gadziriso mabasa eHPMC anogona kushandiswa zvizere, nekudaro achinatsiridza mashandiro uye kukwikwidza kwemusika kwezvinwiwa zvemvura.
