Hydroxyethyl cellulose isiri-ionic mvura-inonyungudika polima yakagadzirwa kubva ku cellulose, yakasikwa polymer zvinhu, kuburikidza nenhevedzano yemakemikari maitiro. Icho chinhu chichena kana chero, chisina kunhuhwirira uye chisina kunaka chakasimba chehupfu, chinogona kunyungudutswa mumvura inotonhora uye mumvura inopisa, uye kuparara kunowedzera nekuwedzera kwekushisa. Kazhinji, haina kunyungudika mune yakawanda organic solvents. Inoshandiswa se thickener uye stabilizer mu latex pendi. Zviri nyore kuparadzira mumvura inotonhora ine pH kukosha isingasviki kana kuenzana ne7, asi zviri nyore kuunganidza mualkaline fluid, saka inowanzogadzirirwa kumberi kuti ishandiswe gare gare, kana isina simba asidhi mvura kana organic solution inogadzirwa kuita slurry. , uye inogonawo kusanganiswa nemamwe granular Zvigadzirwa zvakaoma zvakasanganiswa pamwe chete.
Maitiro ehydroxyethyl cellulose:
HEC inonyungudika mumvura inopisa kana inotonhora, uye haipindi pakupisa kwepamusoro kana kuvira, izvo zvinoita kuti ive nehuwandu hwekunyungudika uye viscosity maitiro, uye kwete-thermal gelation.
Inogona kugarisana neyakasiyana-siyana yemamwe mapolymer anonyungudika mumvura, ma surfactants, uye munyu, uye yakanakisa colloidal thickener yemhinduro dzine high-concentration electrolytes.
Iyo yekuchengeta mvura inokwana zvakapetwa kaviri kupfuura iyo yemethyl cellulose, uye ine zvirinani kuyerera kwemutemo.
Kuenzaniswa neiyo inozivikanwa methyl cellulose uye hydroxypropyl methyl cellulose, kugona kuparadzira kweHEC ndiko kwakaipisisa, asi iyo inodzivirira colloid kugona ndiyo yakasimba.
Kuvaka kwakanakisa; ine zvakanakira zvekuchengetedza-basa, hazvisi nyore kudonha, anti-sag, yakanaka anti-splash, nezvimwe.
Kuenderana kwakanaka neakasiyana surfactants uye mapreservatives anoshandiswa mu latex pendi.
Iyo viscosity yekuchengetedza yakagadzikana, iyo inogona kudzivirira iyo general hydroxyethyl cellulose kubva mukuderedza viscosity ye latex pendi panguva yekuchengetedza nekuda kwekuparara kwema enzymes.
