Kusviba kwehydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ipolymer isinganyungudike mumvura inoshandiswa zvakanyanya se thickener, stabilizer, uye binder mumaindasitiri akasiyana-siyana, anosanganisira mishonga, zvizoro, uye kuvaka. Kusviba kwayo kunoita basa rakakosha pakuona mashandiro ayo mukushandiswa uku.

Kuwanda kweHEC kunoenderana nezvinhu zvakawanda, zvinosanganisira mwero wayo wekutsiva (DS), huremu hwemamorekuru, kuwanda, uye pH. Mwero wekutsiva unoreva huwandu hwemapoka ehydroxyethyl akawedzerwa kumorekuru yecellulose, ukuwo huremu hwemamorekuru hunoreva hukuru hwemacheni epolymer. Kuwanda kweHEC mumushonga kunokanganisawo kuwanda kwayo, nekuwanda kwakanyanya zvichikonzera kuwanda kwakanyanya. pH yemushonga inogonawo kukanganisa kuwanda kwayo, nekuwanda kwepH kazhinji zvichikonzera kuwanda kwakaderera.

Kupenya kweHEC kunogona kuyerwa uchishandisa viscometer, iyo inoyera kuramba kwemvura kuti ifambe. Mhando dzakasiyana dzeviscometer dzinogona kushandiswa, kusanganisira rotational viscometers uye capillary viscometers, zvichienderana nekushandiswa kwayo uye huwandu hwe viscometer hwaunoda.

Kazhinji, HEC yakanyanya kusimba inofarirwa mukushandiswa uko kusimba uye kugadzikana kwakakosha, senge mumishonga, zvizoro, uye zvigadzirwa zvekuchengetedza munhu. Semuenzaniso, HEC yakanyanya kusimba inowanzo shandiswa mushampoos uye conditioners kuti ivandudze magadzirirwo avo uye mashandiro avo, pamwe chete nemakirimu nemafuta ekupa kuti vanzwe vakatsetseka uye vane hunhu hwakanaka.

Muindasitiri yekuvaka, HEC inoshandiswa sechinhu chinosimbisa uye chinochengetedza mvura muzvigadzirwa zvesimende, zvakaita semamortar, grouts, uye concrete. Kusimba kweHEC mukushandiswa uku kwakakosha pakuita kuti chigadzirwa chekupedzisira chishande zvakanaka, chibatanidzwe, uye chienderane.

Kusimba kweHEC kunogonawo kugadziriswa kuburikidza nenzira dzakasiyana-siyana dzemakemikari nefizikisi, kusanganisira crosslinking, acid hydrolysis, uye kusanganisa nedzimwe polymers. Kuchinja uku kunogona kushandura hunhu hweHEC uye kukonzera kushanda kwakanaka mune mamwe mashandisirwo.

Muchidimbu, viscosity yeHEC chinhu chakakosha pakuona mashandiro ayo mukushandiswa kwakasiyana-siyana. Mwero wekutsiva, huremu hwemamorekuru, huwandu, uye pH zvese zvine basa pakuona viscosity yayo, iyo inogona kuyerwa uchishandisa viscometer. Maindasitiri akasiyana uye mashandisirwo anogona kuda mazinga akasiyana eviscosity, uye kugadziriswa kweHEC kunogona kuitwa kuti iwedzere mashandiro ayo mukushandiswa kwakanangana.
