2.3 Indasitiri yekuvaka
Muindasitiri yekuvaka, HEC inowanzoshandiswa mune simende dhaka, gypsum zvigadzirwa uye latex pendi. Mabasa ayo makuru anosanganisira:
Kuomesa uye kuchengetedza mvura: HEC inogona kuvandudza kuenderana kwedhaka uye gypsum, kuwedzera kushanda panguva yekuvaka, uye kuwedzera kuchengetwa kwayo kwemvura, kudzivirira kurasikirwa kwemvura, uye kugadzirisa simba rekubatanidza.
Anti-sagging: Mupendi yelatex, HEC inogona kudzivirira pendi kubva pakudonha panzvimbo yakatwasuka, chengeta yunifomu yekupfekedza, uye kugadzirisa kunaka kwekuvaka.
Kuwedzeredzwa kusungirirwa: HEC inogona kuvandudza kubatana pakati pesamende dhaka uye substrate, kuwedzera simba uye kusimba kwezvinhu.
2.4 Daily Chemical Indasitiri
Iko kushandiswa kukuru kweHEC muzvigadzirwa zvemakemikari zvemazuva ese zvinosanganisira kushandiswa seyakakora, stabilizer uye emulsifier yezvinosuka, shampoos, lotions uye cosmetics. Mabasa ayo anosanganisira:
Kukora: HEC inogona kuwedzera zvakanyanya viscosity yemazuva ese emakemikari zvigadzirwa, zvichiita kuti chigadzirwa chive chakapfava uye chakanaka kushandisa.
Kudzikamisa: HEC ine yakanaka solubility yemvura uye colloid kudzivirira, inogona kudzikamisa iyo emulsified system, kudzivirira kuparadzaniswa kwemafuta-mvura, uye kuwedzera hupenyu hwesherufu yechigadzirwa.
Kumiswa: HEC inogona kumisa zvimedu zvakanaka, kuvandudza kupararira uye kufanana kwechigadzirwa, uye kugadzirisa chitarisiko uye magadzirirwo.
2.5 Pharmaceutical Indasitiri
Muindasitiri yemishonga, HEC inonyanya kushandiswa sebhainda uye inosimudzira-kuburitswa mumiririri, gelling agent uye emulsifier yemapiritsi. Mabasa ayo anosanganisira:
Kusunga: HEC inogona kunyatsosunga zvimedu zvezvinodhaka uye kuvandudza simba remakanika uye kuparara kwekuita kwemapiritsi.
Sustained release: HEC inogona kugadzirisa chiyero chekusunungurwa kwezvinodhaka, kubudirira kusunungurwa kana kudzorwa kusunungurwa migumisiro, uye kugadzirisa kushanda kwezvinodhaka uye kutevedzera murwere.
Gel uye emulsification: HEC inogona kugadzira gel yunifomu kana emulsion mukugadzirwa kwezvinodhaka, kuvandudza kugadzikana uye kuravira kwechirwere.
3. Zvakanakira uye maitiro
3.1 Yakanakisa kukora uye rheological zvivakwa
HEC ine yakanakisa thickening uye rheological modification masimba, ayo anogona zvakanyanya kuwedzera viscosity yeaqueous solutions, zvichiita kuti vazvibate sepseudoplastic fluid pazasi shear rates uye Newtonian fluid pahigh shear rates. Izvi zvinogonesa kuti isangane neiyo rheological zvinodiwa zveakasiyana maindasitiri ekushandisa.
3.2 Kugadzikana uye kuenderana
HEC ine kugadzikana kwakanaka kwemakemikari, inogona kuchengetedza kushanda kwakagadzikana pamusoro pehupamhi hwepH, uye inopindirana nemhando dzakasiyana dzemakemikari uye zvinonyungudutsa. Izvi zvinoigonesa kuchengetedza yakagadzikana gobvu uye kudzikamisa mhedzisiro mune yakaoma makemikari masisitimu.
3.3 Kuchengetedzwa kwezvakatipoteredza uye kuchengetedzwa
HEC yakagadzirwa nemasikirwo cellulose, ine biodegradability yakanaka uye inoshamwaridzana nenharaunda. Panguva imwecheteyo, HEC haina chepfu uye haina kukuvadza, uye yakakodzera kumakemikari ezuva nezuva nemishonga yemishonga ine kuchengetedzwa kwepamusoro zvinodiwa.
Hydroxyethyl cellulose (HEC) ine huwandu hwakawanda hwekushandisa uye inoita basa rakakosha muindasitiri yemakemikari. Kuwedzera kwayo kwakanakisa, rheological properties, kugadzikana uye kuenderana kunoita kuti ive yakakosha yekuwedzera mumaindasitiri mazhinji akadai semajasi, petroleum, kuvaka, makemikari ezuva nezuva uye mishonga yemishonga. Nekuvandudzwa kwehunyanzvi uye shanduko mukudiwa kwemusika, tarisiro yekushandiswa kweHEC ichave yakakura.
