Kushandiswa kwe hydroxyethyl cellulose (HEC) mukuputira kune zvakawanda zvakanakira, kuvhara zvimiro zvemuviri, maitiro ekugadzirisa uye maitiro ekushandisa.
1. Kukora mhedzisiro
Hydroxyethyl cellulose isimba rinoita gobvu iro rinogona kuwedzera zvakanyanya viscosity yekupfeka. Iyo yekukora mhedzisiro inogona kuwana yakakosha mibairo pamatanho ekuwedzera ekuwedzera, nekudaro ichivandudza mashandiro ekushandisa kwejasi. Iyo viscosity yepende ine mwero, iyo inogona kudzivirira matambudziko akadai sekudonha uye kudonha panguva yekupenda, uye kuvandudza kufanana kwekuvaka uye kupfava kweiyo firimu rekuvhara.
2. Kuvandudza kugadzikana
HEC ine yakanaka yekudzikamisa mhedzisiro mumachira. Iyo inogona kudzikamisa kupararira kwe pigment uye mafirita kuburikidza nemuviri muchinjika-kubatanidza uye makemikari kusangana, kudzivirira kugadzirisa uye delamination ye pigment uye mafirita panguva yekuchengetedza kana kushandiswa. Izvi hazvingowedzere hupenyu hwesherufu yepende asi zvakare inovimbisa kugovaniswa kwe pigment panguva yekushandiswa.
3. Kuvandudza rheology
Hydroxyethyl cellulose ine simba rakakosha pane rheology yejasi, zvichiita kuti iyo yekupfeka iratidze pseudoplastic (shear thinning) zvivakwa. Payero yakaderera shear, pende inochengetedza yakakwira viscosity, iyo yakanakira kumira uye kuchengetedza; apo pakakwirira shear rates (sekunge uchikwesha uye kupfapfaidza), viscosity yepende inoderera, zvichiita kuti zvive nyore kuyerera uye kushandisa. Ichi chifukidzo chekuveura-shear chinoita kuti kupfekedzwa kuve nyore kushandisa panguva yekushandiswa, uye iyo yekubikira firimu inotsvedzerera uye kunyange.
4. Kuvandudza sag resistance
Kana uchiisa pendi panzvimbo dzakamira, HEC inogona kuvandudza zvakanyanya kuramba kwependi kuti isag. Izvi zvinokonzerwa nekuita kwayo kukora uye rheological properties inobvumira pendi kuti ikurumidze kuumba gel-yakafanana chimiro mushure mekushandisa, kuderedza maitiro ekuyerera, nokudaro kudzivirira pendi kubva pakudonha uye kupera.
5. Wedzera zvinyoro zvinyoro
HEC inonyatso chengetedza unyoro, nekudaro ichiwedzera nguva yekuomesa yepende. Izvi zvinonyanya kukosha kune mamwe machira anoda nguva yakareba yekushanda, yakadai sepende yehuni, pende yekugadzira, nezvimwewo. Nguva yakawedzerwa yekuomeswa inopa muvaki nguva yakawanda yekushanda uye inodzivisa kupenda zviratidzo uye matambudziko ekuvaka anokonzerwa nekunyanya kuoma kwepende.
6. Kuvandudza kushanda kwebhurashi
Sezvo HEC ichivandudza rheological zvimiro uye kukora mhedzisiro yepende, iyo pendi inoratidza zvirinani kuenzana kana yakabhurwa. Paunenge uchikwesha, pende inogona kupararira zvakaenzana pasina mabrashi, uye iyo yekupedzisira yekuputira firimu inotsvedza uye yakapfava. Izvi zvinonyanya kukosha kune zvemhando yepamusoro zvekupfeka, senge fenicha yekupfekedza, majasi emotokari, nezvimwe.
7. Chinochinjika
HEC ine kugadzikana kwakanaka kwemakemikari uye kuwirirana uye inopindirana nemhando dzakasiyana-siyana dzekuputira, dzakadai semvura-based coatings, latex paints, mafuta-based paints, etc. Iine kushanduka kwakasiyana kune zvakasiyana-siyana uye zvigadzirwa, hazvizoiti zvakashata nezvimwe. zvinosanganisa, uye hazvizokonzeresa shanduko yemakemikari mune fomula.
8. Kuvandudza coating performance
HEC haingopei kukora uye kudzikamisa mhedzisiro mumajasi, asi zvakare inovandudza maitiro emuviri weiyo firimu rekuvhara. Semuyenzaniso, inogona kuvandudza kuputika kupikisa, kukwesha kuramba uye kuchinjika kweiyo firimu rekuvhara. Izvi zvinoita kuti kuvhara kwekupedzisira kuve kwakasimba, kukwanisa kuchengetedza kunaka kwayo uye kushanda pasi pezvakasiyana-siyana zvezvakatipoteredza.
9. Kuchengetedza kwezvakatipoteredza
HEC ndeye biodegradable material ine yakanaka kuchengetedza nharaunda. Kana ichienzaniswa nemamwe masimbi ekugadzira, ine mitoro shoma yezvakatipoteredza uye haiburitse zvinhu zvinokuvadza panguva yekushandiswa. Izvi zvinofambirana nepamusoro pekuchengetedzwa kwezvakatipoteredza zvinodiwa zvemazuva ano ekupfekedza indasitiri uye zvakare inochinja kune kudiwa kwevatengi kwezvakasvibirira zvigadzirwa.
10. Zviri nyore kubata uye kuparadzira
HEC inonyungudika nyore uye inopararira mumvura uye inoita yunifomu viscous fluid. Mukugadzira kugadzirwa kwekuvhara, kunyungudika uye kupararira kunoita kuti maitiro ekugadzira ave nyore uye asanyanya kutarisana nezvinetso zvekusangana kana kusakwana kuparara, kuderedza dambudziko mukugadzira uye kuvandudza hunyanzvi hwekugadzira.
Iko kushandiswa kwehydroxyethyl cellulose mumachira kune zvakawanda zvakanaka. Haisi kungovandudza zvinhu zvemuviri uye kushanda kwekuvaka kwekuputira, asiwo kunowedzera kugadzikana uye kuchengetedzwa kwezvakatipoteredza maitiro ekuputira. Inoita basa rakakosha mukugadzirwa kwependi yemazuva ano, ichipa mhinduro dzinoshanda dzekuwana emhando yepamusoro pendi mhedzisiro. Nekuvandudzwa kwetekinoroji yekupfeka uye kusiyanisa kwemusika kudiwa, tarisiro yekushandiswa kweHEC mumachira ichave yakakura.
