Hydroxyethyl cellulose (HEC) yakakosha isiri-ionic mvura-inonyungudika yepolymer komboni ine huwandu hwakawanda hwekushandisa muindasitiri yependi uye yekupfeka.
1. Mukobvu
Hydroxyethyl cellulose inonyanya kushanda mukobvu. Inogona kuwedzera viscosity yepende nekutora mvura mumushonga wemvura wekuwedzera uye kugadzira colloidal solution. Izvi hazvingobatsiri kudzivirira pendi kuti isagadzikane panguva yekuchengetedza uye yekufambisa, asi zvakare inovandudza kuenzana kwayo nekumisa zvimiro, kuve nechokwadi chekufanana uye kutsvedzerera kwependi yekuputira.
2. Rheological control
Hydroxyethyl cellulose inogona kugadzirisa rheological zvimiro zvepende, ndiko kuti, shandura kuyerera kwayo hunhu pane akasiyana shear mitengo. Inogona kuchengeta pendi pane imwe viscosity mune static state kudzivirira kudonha; uye panguva yekushanda kwekushanda, viscosity ichaderera nekuwedzera kweshear rate, iyo iri nyore pakuvaka. Iyi pfuma inobatsira kuvandudza kuvaka uye kushanda zvakanaka kwepende.
3. Kuchengeta mvura
Hydroxyethyl cellulose ine yakanakisa kuchengetedza mvura. Inogona kunyatso kudzivirira kubuda kwemvura nekukurumidza, nekudaro kuwedzera nguva yekuomeswa kwepende uye kubvumira firimu repende kuti rive nenguva yakakwana yekuenzanisa uye kugadzira firimu panguva yekuomesa. Izvi zvinonyanya kukosha pamvura-based paints, sezvo kukurumidza kurasikirwa kwemvura kunogona kukonzera matambudziko akadai sepini uye kuputika mufirimu yepende.
4. Kugadzikana uye kupesana-kugadzirisa zvinhu
Mukugadzira pendi, kunyanya masisitimu ane akasimba pigment uye mafirita, hydroxyethyl cellulose inogona kupa yakanaka kumiswa kugadzikana kuburikidza nekukora. Inogona kudzivirira zvinobudirira sedimentation yepigment uye mafirita, kuve nechokwadi chekuumbwa kwependi panguva yekuchengetera, uye nekudaro kuve nechokwadi chekuenderana kwemavara uye kugadzikana kwekuita kwejasi.
5. Kuvandudza maitiro ekugadzira mafirimu
Hydroxyethyl cellulose inogona kuwedzera firimu-kuumba zvimiro zvependi. Inogona kuumba yunifomu yefirimu firimu pamusoro pepamusoro pekuvhara, kuvandudza kubwinya uye kufanana kwefirimu yepende. Mukuwedzera, hydroxyethyl cellulose inogonawo kuvandudza anti-powdering uye kudzivirira mvura kwefirimu yekuputira, kuwedzera kusimba kwayo uye kushongedza zvinhu.
6. Zvivakwa zvezvakatipoteredza
Senge isiri-ionic thickener, hydroxyethyl cellulose haina simbi inorema uye zvinonyungudutsa zvinokuvadza, uye inosangana nekuchengetedzwa kwezvakatipoteredza. Kushandiswa kwaro mumapendi ane mvura kunogona kuderedza zviri mukati memhepo inopisa organic compounds (VOCs), iyo inobatsira kuderedza kusvibiswa kune zvakatipoteredza uye kukuvadza kuhutano hwevanhu.
Iko kushandiswa kwehydroxyethyl cellulose mupende haingogadzirise zvimiro zvemuviri uye kuita kwekuvaka kwechigadzirwa, asi zvakare inosangana nekuchengetedzwa kwezvakatipoteredza uye kuchengetedza zvinodiwa zveindasitiri yemazuva ano yekupfeka. Sekuwedzera kwakawanda, inoita basa rakakosha mukugadzira dhizaini uye maitiro ekushandisa pendi.
