Viscosity ye hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) is nonionic, mvura-soluble polymer iyo inoshandiswa zvakanyanya seyakakora, stabilizer, uye binder mumaindasitiri akasiyana siyana, anosanganisira emishonga, zvizorwa, uye kuvaka. Viscosity yayo inoita basa rakakosha pakuona kuita kwayo muzvishandiso izvi.

Iyo viscosity yeHEC inotarirwa nehuwandu hwezvinhu, kusanganisira dhigirii rayo rekutsiva (DS), uremu hwemamorekuru, kutarisisa, uye pH. Iyo dhigirii yekutsiva inoreva huwandu hwemapoka ehydroxyethyl akawedzerwa kune cellulose molecule, ukuwo huremu hwemamorekuru hunoreva saizi yemacheni epolymer. Iko kusungirirwa kweHEC mumhinduro kunokanganisawo viscosity yayo, nepamusoro-soro inoguma nepamusoro viscosity. Iyo pH yemushonga inogona zvakare kuve nemhedzisiro pane viscosity, ine yakakwirira pH kukosha kazhinji ichikonzera yakaderera viscosity.

Iyo viscosity yeHEC inogona kuyerwa uchishandisa viscometer, iyo inoyera kuramba kwemvura kuyerera. Mhando dzakasiyana dzemaviscometers dzinogona kushandiswa, kusanganisira rotational viscometers uye capillary viscometers, zvichienderana neiyo chaiyo application uye viscosity siyana yekufarira.

Kazhinji, viscosity yepamusoro HEC inosarudzwa mumashandisirwo uko kukora uye kudzikamisa kwakakosha, senge mukugadzirwa kwemishonga, zvizorwa, uye zvigadzirwa zvekuchengeta munhu. Semuenzaniso, high viscosity HEC inowanzo shandiswa mumashamposi uye maconditioners kuti avandudze magadzirirwo nekuita kwavo, pamwe nemafuta uye mafuta ekuzora kuti ape yakatsetseka, yakasarudzika kunzwa.

Muindasitiri yekuvaka, HEC inoshandiswa seyakakora uye yekuchengeta mvura muzvigadzirwa-simende, senge madhaka, grouts, uye kongiri. Iyo viscosity yeHEC mune izvi zvikumbiro yakakosha pakuwana inodiwa kushanda, kunamatira, uye kuenderana kwechigadzirwa chekupedzisira.

Iyo viscosity yeHEC inogona zvakare kugadziridzwa kuburikidza neakasiyana makemikari uye emuviri nzira, kusanganisira kuyambuka, acid hydrolysis, uye kusanganisa nemamwe mapolymer. Izvi zvinogadziridzwa zvinogona kushandura zvimiro zveHEC uye zvinokonzeresa kukwidziridzwa kwekuita mune chaiwo maapplication.

Mukupfupisa, viscosity yeHEC chinhu chakakosha pakugadzirisa kushanda kwayo mune zvakasiyana-siyana zvekushandisa. Iyo dhigirii yekutsiva, huremu hwemamorekuru, kutarisisa, uye pH zvese zvine basa mukuona viscosity yayo, iyo inogona kuyerwa uchishandisa viscometer. Maindasitiri akasiyana uye mashandisirwo angangoda mazinga akasiyana eviscosity, uye shanduko kuHEC inogona kuitwa kuti iwedzere kuita kwayo mune chaiyo maapplication.
