Hydroxyethyl cellulose (HEC) isiri-ionic cellulose ether yakagadzirwa kubva kune yakasikwa polymer material cellulose kuburikidza nenhevedzano ye 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
coating
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.
zvivakwa
Mumunda weindasitiri yekuvaka, HEC inoshandiswa sekuwedzera kune zvinhu zvakaita semadziro emadziro, kongiri (kusanganisira asphalt), matiles akaiswa uye caulking zvinhu.
Zviwedzerwa zvinogona kuwedzera viscosity uye kukora kwezvinhu zvekuvaka, kunatsiridza kunamatira, lubricity, uye kuchengetwa kwemvura, kuwedzera kusimba kwekushanduka kwezvikamu kana zvikamu, kunatsiridza shrinkage, uye kudzivirira kuputika.
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.
makemikari ezuva nezuva
Cellulose ether chinhu chakakosha chekuwedzera mune zvemazuva ese makemikari zvigadzirwa. Haikwanise kungovandudza viscosity yemvura kana emulsion cosmetics, asiwo inovandudza kupararira uye kugadzikana kwefuro.
kugadzira mapepa
Mumunda wekugadzira mapepa, HEC inogona kushandiswa senge saizi mumiriri, inosimbisa mumiriri uye pepa rekugadzirisa.
kuchera mafuta
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 kuma1960s.
Mamwe minda yekushandisa
kurima
Hydroxyethyl cellulose (HEC) inogona kunyatso kumisa chepfu yakasimba mumvura-based sprays.
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; sechinamira mukudzokorodza mashizha efodya.
moto
Hydroxyethyl cellulose inogona kushandiswa sechinhu chinowedzera kuwedzera kuvharika kwekushanda kwezvinhu zvisingatsva nemoto, uye yakashandiswa zvakanyanya mukugadzirira kwe "thickeners" dzisingapindi moto.
forging
Hydroxyethylcellulose inogona kuvandudza simba rakanyorova uye kuderera kwejecha resimende uye sodium silicate jecha masisitimu.
Microscopy
Hydroxyethyl cellulose inogona kushandiswa mukugadzira mafirimu uye seanoparadzira mukugadzirwa kwemasiraidhi asingaoneki.
Thickener mune yakakwira munyu yekuisa zvinwiwa zvinoshandiswa kugadzira firimu.
fluorescent chubhu pendi
Inoshandiswa sebhainda uye yakagadzikana dispersant yefluorescent agents mune fluorescent chubhu coatings.
Electroplating uye Electrolysis
Inogona kudzivirira iyo colloid kubva pakubata kwe electrolyte concentration; hydroxyethyl cellulose inogona kukurudzira yunifomu deposition mune cadmium plating mhinduro.
Ceramics
Inogona kushandiswa kugadzira mabhaidha akasimba-akasimba emakeramiki.
cable
Zvinodzingisa mvura zvinodzivirira mwando kupinda mumatambo akakuvadzwa.
