Kuwedzera viscosity ye cellulose ethers kazhinji kunoderedza kuyerera kwemhinduro. Cellulose ethers iboka remapolima anonyungudika nemvura anobva muselulosi ayo anowanzoshandiswa mumaindasitiri akasiyana siyana, anosanganisira emishonga, chikafu, uye kuvaka. Iyo viscosity yemushonga chiyero chekuramba kwayo kuyerera uye inobatwa nezvinhu zvakaita sekutarisa, tembiricha, uye huremu hwemamorekuru hwe cellulose ether.
Heino tsananguro yakadzama yekuti kuwedzera cellulose ether viscosity kunokanganisa sei kuyerera:
Hukama pakati pe viscosity uye kuyerera mwero:
Viscosity ndiko kukwesha kwemukati mukati memvura inopokana nekuyerera kwayo. Inopimwa mumayuniti akadai secentipoise (cP) kana kuti pascal seconds (Pa·s).
Kuyerera kweyero yemhinduro kunopesana nekuenzanisa kwayo viscosity. Higher viscosity inoreva kuramba kukuru kuyerera, zvichikonzera kuderera kwekuyerera.
Cellulose ether zvinhu:
Cellulose ethers inowanzowedzerwa kune mhinduro kugadzirisa rheological properties. Mhando dzakajairika dzinosanganisira methylcellulose (MC), hydroxypropylcellulose (HPC), uye carboxymethylcellulose (CMC).
Iyo viscosity ye cellulose ether mhinduro inoenderana nezvinhu zvakaita sekutarisa, tembiricha uye shear rate.
Concentration effect:
Kuwedzera kuwanda kwe cellulose ethers kazhinji kunowedzera viscosity. Izvi zvinodaro nekuti kukwirisa kunoreva mamwe macheni epolymer mumhinduro, zvichikonzera kuramba kwakanyanya kuyerera.
Temperature effect:
Tembiricha inokanganisa viscosity ye cellulose ethers. Mune zvimwe zviitiko, sezvo tembiricha inowedzera, viscosity inoderera. Nekudaro, hukama uhu hunogona kusiyana zvichienderana neiyo chaiyo cellulose ether mhando uye mhinduro yayo.
Shear rate dependence:
Iko viscosity ye cellulose ether zvinogadzirisa zvinowanzoenderana neshear rate. Pamazinga epamusoro ekugera (semuenzaniso, panguva yekupomba kana kusanganisa), viscosity inogona kuderera nekuda kwekuveura kutetepa maitiro.
Impact patraffic:
Kuwedzera cellulose ether viscosity kunogona kukonzera kuderedzwa kuyerera kwemazinga mumaitiro anoda kutakura, kupomba, kana kugovera mhinduro. Izvi zvinoshanda kune zvikumbiro zvakaita semajasi, zvinonamira uye kugadzirwa kwemishonga.
Zvinyorwa zvekushandisa:
Nepo maviscosity epamusoro angave achidikanwa mune mamwe maapplication ekuvandudza mashandiro echigadzirwa kana kugadzikana, izvi zvinofanirwa kuenzana nemaitiro anoshanda ekubata nekugadzirisa.
Recipe optimization:
Maformulators anowanzo optimize cellulose ether concentration uye mamwe maparameter ekugadzira kuti awane viscosity inodiwa kune chaiyo application pasina kukanganisa kuyerera kune isingagamuchirwe dhigirii.
Kuwedzera cellulose ether viscosity kazhinji kunoguma nekuderera kwekuyerera kwehuwandu nekuda kwekuwedzera kuyerera kwekudzivirira. Zvisinei, hukama chaihwo hunokanganiswa nezvinhu zvakadai sekufungisisa, tembiricha uye shear rate, uye kugadziriswa kwekugadzirisa kunogona kuitwa kuti uwane chiyero chinodiwa pakati pe viscosity uye kuyerera.
