Chii chinonzi Hydroxyethyl Cellulose chinoshandiswa?

Hydroxyethyl cellulose(HEC) isiri-ionic cellulose ether yakagadzirwa kubva kune yakasikwa polymer material cellulose kuburikidza nekutevedzana kwe etherification. Iyo isina kunhuhwirira, isinganakidze, isina-chepfu chena poda kana granule, inogona kunyungudutswa mumvura inotonhora kuti igadzire yakajeka viscous mhinduro, uye kunyungudika hakukanganiswe neiyo pH kukosha. Iine kukora, kusunga, kuparadzira, emulsifying, firimu-kuumba, kumisa, adsorbing, kushanda kwepamusoro, kuchengetedza unyoro uye kusagadzikana kwemunyu. Inoshandiswa zvakanyanya mupende, kuvaka, machira, makemikari ezuva nezuva, mapepa, kuchera mafuta uye mamwe maindasitiri.

Main application nzvimbo:

1.Paint:Pendi yakavakirwa pamvura imvura inopenya inogadzirwa ne organic solvents kana mvura inoenderana neresin, kana mafuta, kana emulsion, pamwe nekuwedzerwa kwezvinowedzera zvinoenderana. Mvura-based coatings ine basa rakanakisa inofanirawo kuva nekushanda kwakanakisisa kwekushanda, simba rekuvanda rakanaka, kusungirirwa kwakasimba kwekunamatira, uye kushanda kwakanaka kwekuchengetedza mvura; cellulose ether ndiyo yakanyatsokodzera mbishi zvinhu kupa izvi zvivakwa.

2.Cmurayiro:Mumunda weindasitiri yekuvaka, HEC inoshandiswa sekuwedzera kwezvinhu zvakaita semadziro, kongiri (kusanganisira asphalt), matiles akaiswa uye zvinhu zvekugadzira, izvo zvinogona kuwedzera viscosity uye kukora kwezvinhu zvekuvaka, kunatsiridza kunamatira, lubricity, uye mvura. kuchengetedza. Wedzera kusimba kwekushanduka kwezvikamu kana zvikamu, vandudza shrinkage, uye kudzivirira kumucheto kutsemuka.

3.Textile:HEC-yakagadzirwa nekotoni, synthetic fibers kana misanganiswa inovandudza zvimiro zvavo senge abrasion resistance, dyeability, fire resistance and stain resistance, pamwe nekuvandudza kugadzikana kwemuviri wavo (shrinkage) uye kusimba, kunyanya kune masynthetic fibers, izvo zvinoita kuti zvifeme uye zvinoderedza static. magetsi.

4.Daily chemical:Cellulose ether chinhu chakakosha chekuwedzera mune zvemazuva ese makemikari zvigadzirwa. Haikwanise kungovandudza viscosity yemvura kana emulsion cosmetics, asiwo inovandudza kupararira uye kugadzikana kwefuro.

5.Pepa:Mumunda wekugadzira mapepa, HEC inogona kushandiswa senge saizi mumiriri, inosimbisa mumiriri uye pepa rekugadzirisa.

6.Oil drilling:HEC inonyanya kushandiswa seyakakora uye inodzikamisa mumiriri mune oirifield kurapwa maitiro. Ikemikari yakanaka yemunda wemafuta. Yaishandiswa zvakanyanya mukuchera, kupedzisa matsime, simende uye mamwe mabasa ekugadzira oiri munyika dzekunze kuma1960.

Mamwe minda yekushandisa:

HEC inogona kuita basa rekunamatira chepfu kumashizha mukupfapfaidza mabasa; HEC inogona kushandiswa seyakakora yekupfapfaidza emulsions kuderedza kudonha kwezvinodhaka, nekudaro ichiwedzera kushandiswa kwefoliar spraying. HEC inogona zvakare kushandiswa semugadziri wekugadzira firimu mune mbeu yekuputira mbeu; sebhinda mukudzokorodza mashizha efodya. Hydroxyethyl cellulose inogona kushandiswa sechinhu chinowedzera kuwedzera kuvharidzira kushanda kwezvinhu zvisingasviki moto, uye yakashandiswa zvakanyanya mukugadzirira kwemoto "thickeners". Hydroxyethyl cellulose inogona kuvandudza simba rakanyorova uye kuderera kwejecha resimende uye sodium silicate jecha masisitimu.Hydroxyethyl cellulose inogona kushandiswa mukugadzira mafirimu uye seanoparadzira mukugadzirwa kwemasiraidhi asingaoneki. Thickener mune zvinwiwa zvine munyu wakawanda wakawanda unoshandiswa mukugadzira firimu. Inoshandiswa sebhainda uye yakagadzikana dispersant yefluorescent agents mune fluorescent chubhu coatings. Inogona kudzivirira iyo colloid kubva pakubata kwe electrolyte concentration; hydroxyethyl cellulose inogona kukurudzira yunifomu deposition mune cadmium plating mhinduro. Inogona kushandiswa kugadzira mabhaidha akasimba-akasimba emakeramiki. Zvinodzingisa mvura zvinodzivirira mwando kupinda mumatambo akakuvadzwa.
