Hydroxyethyl cellulose (HEC)i-non-ionic cellulose ether yakagadzirwa ne cellulose yemhando ye polymer kuburikidza ne etherification yakatevedzana. Iupfu huchena kana granule isina hwema, isina kuravira, isina chepfu, inogona kunyungudutswa mumvura inotonhora kuti igadzire mhinduro yakajeka ine viscous, uye kunyunguduka hakukanganisike ne pH value. Ine kukora, kusunga, kuparadzira, emulsifying, film-forming, suspending, adsorbing, surface active, moisture-retaining uye salt-resistant. Inoshandiswa zvakanyanya mupendi, kuvaka, machira, makemikari ezuva nezuva, bepa, oiri drilling nedzimwe nzvimbo.
Nzvimbo huru dzekushandisa:
1. Pendi: Pendi ine mvura imvura inonamira yakagadzirwa ne organic solvents kana mvura inobva pa resin, kana mafuta, kana emulsion, pamwe nekuwedzera zvimwe zvinoenderana. Mapendi ane mvura ane mashandiro akanaka anofanirawo kuva nekushanda kwakanaka, simba rakanaka rekuviga, kunamira kwakasimba kwepanti, uye kushanda zvakanaka kwekuchengetedza mvura; cellulose ether ndiyo inonyanya kukodzera kugadzira zvinhu izvi.
2. Kuvaka: Mundima yekuvaka, HEC inoshandiswa sechinhu chinowedzera zvinhu zvakaita semadziro, kongiri (kusanganisira asphalt), mataira akasungirirwa nezvinhu zvinosunga madziro, izvo zvinogona kuwedzera kukora kwezvinhu zvekuvaka, kunatsiridza kunamira, kunyorova, uye kuchengetedza mvura. Wedzera simba rekuchinjika kwezvikamu kana zvikamu, kunatsiridza kudonha, uye kudzivirira kutsemuka kwemucheto.
3. Machira: donje rakagadziriswa neHEC, machira ekugadzira kana misanganiswa inovandudza hunhu hwayo hwakadai sekudzivirira kukwesha, kudhaya, kutsva uye kuramba mavara, pamwe nekuvandudza kugadzikana kwemuviri wayo (kuderera) uye kugara kwenguva refu, kunyanya machira ekugadzira, izvo zvinoita kuti ikwanise kufema uye kuderedza magetsi asingachinji.
4. Kemikari yezuva nezuva: Cellulose ether chinhu chakakosha muzvigadzirwa zvemakemikari zvezuva nezuva. Haingogone chete kuvandudza viscosity yezvizoro zvemvura kana emulsion, asiwo inovandudza kupararira uye kugadzikana kwefuro.
5.Pepa: Mubasa rekugadzira mapepa, HEC inogona kushandiswa semushonga wekuisa saizi, mushonga wekusimbisa uye mugadziri wepepa.
6. Kuchera mafuta: HEC inonyanya kushandiswa sechinhu chinosimbisa uye chinosimbisa kugadzirwa kwemafuta. Ikemikari yakanaka yemafuta. Yakashandiswa zvakanyanya mukuchera, kupedzisa matsime, kusimbisa uye mamwe mabasa ekugadzira mafuta munyika dzekunze muma1960.
Mimwe minda yekushandiswa:
HECinogona kuita basa rekunamatira chepfu pamashizha mumabasa ekupfapfaidza; HEC inogona kushandiswa sechinhu chinosimbisa ma emulsions ekupfapfaidza kuderedza kuyerera kwemishonga, nokudaro ichiwedzera simba rekushandisa kupfapfaidza mashizha. HEC inogona zvakare kushandiswa sechinhu chinoumba firimu muzvishandiso zvekufukidza mbeu; sechinhu chinosunga mashizha efodya. Hydroxyethyl cellulose inogona kushandiswa sechinhu chinowedzera simba rekufukidza zvinhu zvisingatsvi, uye yakashandiswa zvakanyanya mukugadzira "zvinodzivirira moto". Hydroxyethyl cellulose inogona kuvandudza simba remvura uye kuderera kwejecha resimende uye sodium silicate sand systems. Hydroxyethyl cellulose inogona kushandiswa mukugadzira mafirimu uye sechinhu chinoparadzanisa mukugadzira masiraidhi madiki. Chinosimbisa mumvura ine munyu wakawanda inoshandiswa mukugadzirisa mafirimu. Inoshandiswa sechinobatanidza uye chinoparadzanisa stable ye fluorescent agents mu fluorescent tube coatings. Inogona kudzivirira colloid kubva pakukanganiswa kwe electrolyte concentration; hydroxyethyl cellulose inogona kukurudzira kuiswa kwakafanana mu cadmium plating solution. Inogona kushandiswa kugadzira zvibatiso zvine simba guru zve ceramics. Zvinodzivirira mvura zvinodzivirira hunyoro kuti husapinde mutambo dzakakuvara.
