Ndezvipi zvinhu zvinokanganisa zvevisiko zve hydroxypruppropyl methylcellose?

Yekushandiswa kweiyo yakanyorova dhaka,hydroxypruppropyl methylcelloseine zvinhu zvakanaka zvakakura, zvinogona kuwedzera kugona kwekurongedza pakati pekunyoroveswa pakati pemuchina, uyezve zvinoshandiswa zvakanyanya muguruva, kunze kwemadziro ekunze system uye zvidhinha.

Zvekuita kwakakora kwemasero ether, zvinogona zvakare kuwedzera homogeneity neanti-kupararira kugona kwezvinhu zvakavanzika zvekende-zvakavakirwa, uye zvinogona zvakare kudzivirira matambudziko ekugadzikana, kusaririra uye kubuda ropa murufu uye kongiri. Inogona kuiswa kune fiber-yakasimbiswa kongiri, pasi pemvura kongiri uye yekuzvibata-converting kongiri.

Hydroxyprupylpropyl methylcellose inogona kuwedzera iyo viscous mashandiro ezve cement-based zvigadzirwa. Kuita uku kwakanyanya kunobva pane viscosity ye cellulose ether mhinduro. Kazhinji, indekisi yehuwandu hwe viscosity inoshandiswa kutonga viscosity ye cellulose gadziriso yekunyora mherether mhinduro, kazhinji 2% tembiricha, yakadai se2 degrees uye chiyero chinotenderera, uchishandisa chishandiso chakataurwa, chakadai senzvimbo yekutenderera. Viscosity kukosha.

Viscosity ndeimwe yeakakosha parameter kuti vatonge mashandisirwo emheremalose ether. Yakakwira iyo viscosity ye hydroxyprosyl methylcellose solution solution, zviri nani zvisizvo zveSement-based zvigadzirwa, uye zviri nani kudenha kuita kune substrate. Panguva imwecheteyo, ine kugona kwekunyepedzera uye kugona kwekuparadzira-kurwisa kwakasimba, asi kana visikoity yakanyanya kukwirira, ichakanganisa kuyerera uye kuiswa kwezvinhu zvakasvibirira.

Ndezvipi zvinhu zvinokanganisa zvevisiko zve hydroxypruppropyl methylcellose? Kunyanya zvinoenderana nezvikonzero zvinotevera.

1. Iyo yakakwira mwero wePolymerization yeCellulose yeHydroxyPropropropylsl methylcellose, iyo yakakura srewlar uremu, zvichikonzera kuwanda kwemisangano yemhedzisiro yayo mhinduro.

2. Kana iyo huwandu kana kusunganidzwa kwemherekukweretesa ether yakakwira, iyo yekutsanangura kwayo mhinduro kwayo ichave yakakwira. Nekudaro, hanya kunofanirwa kutorwa kuti usarudze huwandu hwakakodzera hwemasero e cellulose ether paunenge uchishandisa, kunyanya kudzivisa zvakanyanya huwandu hweCellulose ether. Izvo zvichakanganisa mashandiro emota uye kongiri.

3. Kufanana nezvakawanda zvinwiwa, iyo viscosity ye cellulose gadziriso mhinduro ichaderera nekuwedzera kwekushisa, uye kumusoro kwekusangana kwemherekuru ether, iyo yakadzika tembiricha. Kukanganisa kukuru.

4. Cellulose ether mhinduro kazhinji inowanzoita pseudoplasticastic, iyo ine hunhu hwekutetepa. Iyo yakakura iyo Shear rate panguva yekuedzwa, iyo diki iyo viscosity.

COOHES YEMADZIMAI ichadzikiswa nekuda kwekuita kwesimba rekunze, iro rinobatsirawo pakuvaka kwekuvhunduka kwevhu, zvichikonzera kubatana kwakanaka panguva imwe chete. Nekudaro, kana iyocellulose etherSolution ine kushushikana kwakanyanya apo viscosity yakaderera uye visikoka idiki, icharatidza hunhu hweNewotian Fluid. Kana iko kuwanda kwacho kuchikwanisika, mhinduro icharatidza zvishoma nezvishoma hunhu hwe pseudoplastic fluid, uye kana kusarongeka kwakakwira, pseudoplasticasticasity ichave pachena.
