Cellulose ether viscosity bvunzo

Iyo viscosity yecellulose etana, akadai se hydroxyprupyl methylcellose (HPMC) kana CarboxyMethyl Cellerosel Cellerose (CMC), iparamende yakakosha inogona kukanganisa maitiro avo mune dzakasiyana siyana. Viscosity chiyero chekuramba kwemvura kuyerera, uye zvinogona kufurirwa nezvinhu zvakadai sekusundika, tembiricha, uye degree rekutsiva cellulose ether.

Heano general gwara rekutarisa kwema tiscosity emasangano e cellulose ana etero inogona kuitiswa:

Brookfield visccometer nzira:

Iyo Brookfield VisaCometer chiitiko chakajairika chinoshandiswa kuyera visikoka yemvura. Matanho anotevera anopa basi rehurukuro yekuitisa bvunzo yeViscosity:

1. Kuenzanisira Kuenzanisa:
   • Gadzirira kuzivikanwa kwekuzivikanwa kwe cellulose ether mhinduro. Iko kusarudzika kwakasanangurwa kunoenderana nezvakananga zvinodiwa zvekushandisa.
2. Tembiricha yakaenzana:
   • Ita shuwa kuti sampuli yakaenzana kune inodiwa yekuyedza tembiricha. Viscosity inogona kuve tembiricha-inotsamira, saka kuyedza pakudziya kwakadzorwa kwakakosha kuti zviyero zvechokwadi.
3. Calibration:
   • Calibrate iyo Brookfield Viscometer ichishandisa yakajairika calibration yemvura yekuverenga mvura kuti ive nechokwadi chakaringana kuverenga.
4. Kuisa muenzaniso:
   • Isa huwandu hwakakwana hwe cellulose ether mhinduro mu piscometer chamber.
5. Kusarudzwa kweSpindle:
   • Sarudza iyo yakakodzera spindle yakavakirwa pane iyo inotarisirwa viscossity mhando yemuenzaniso. Dzakasiyana spindles dzinowanikwa kune yakaderera, yepakati, uye yakakwira viscosity.
6. Kuyerwa:
   • Nyudza iyo scindle mumuenzaniso, uye tanga iyo viscometer. Iyo spindle inotenderera nekumhanya nguva dzose, uye kuramba kutenderera kunoyerwa.
7. Kurekodha data:
   • Rekodha iyo viscosity kuverenga kubva kuViscometer kuratidza. Iyo unit yekuyerwa kazhinji mune centipoise (CP) kana millipascal-masekondi (MPA · ·).
8. Dzokorora zviyero:
   • Kuitisa miyedzo yakawanda kuti ive nechokwadi chekubereka. Kana viscosity vachisiyana nenguva, zviyero zvekuwedzera zvinogona kunge zvichidikanwa.
9. Kuongorora kwedata:
   • Ongorora iyo viscosity data muchinyorwa chechishandiso chinodiwa. Kushandiswa kwakasiyana kunogona kuve neiyo viscosity tarisiro.

Zvinhu zvinokanganisa viscosity:

1. Kusimbisa:
   • Nzvimbo dzakakwirira dzepamusoro dze cellulose ether mhinduro dzinowanzoguma nekukoshesa visikoka.
2. Tembiricha.
   • Viscosity inogona kuve tembiricha-inotyisa. Kupisa kwakanyanya kunogona kuderedza viscossity.
3. Degree rekutsiva:
   • Dhigirii rekutsiva kwemhereme cellulose ether inogona kukanganisa kururamisa kwayo uye, nekudaro, viscosity yayo.
4. Shear Rate:
   • Viscosity inogona kusiyana nehasha shear, uye dzakasiyana viscometers dzinogona kushanda pamitengo yakasiyana.

Gara uchitevera mirayiridzo chaiyo inopihwa nemugadziri weiyo cellucerse ether yekuongororwa kwekuona, sezvo maitiro anogona kusiyana zvichienderana nerudzi rwechinguvana ether uye chaicho chinangwa.
