Hydroxypropyl methylcellulose haina kukuvadza kumuviri wemunhu, hydroxypropyl methyl cellulose yakachengeteka uye haina chepfu, inogona kushandiswa sekuwedzera chikafu, haina kupisa, uye haina kutsamwa paganda uye mucous membrane kusangana. Kazhinji inofungidzirwa kuve yakachengeteka zuva nezuva inotenderwa kunwa ye25mg / kg, zvekuchengetedza zvinofanirwa kupfekwa panguva yekushanda.

Vakadzi vanoyamwisa vanonwisa pavanenge vachishandisa mushonga, uye hapana maitiro akashata akataurwa mune vacheche. Naizvozvo, hapana akakosha kurwisa vakadzi vane pamuviri uye vanonamatira. Iko kushandiswa kweiyo hypromellose muvana hakuchikonzeri maitiro akashata achienzaniswa nemamwe mapoka ezera, saka vana vanogona kushandisa chigadzirwa ichi muchirongwa chimwe chete sevakuru.

Ruzivo rwakawedzerwa

Hunhu hwehydroxypropyl methylcellulose

1. Iyo yakakwira mwero wepolymerization ye cellulose ether, yakakura iyo huremu hwehuremu, uye yakakwira kuoneka kweyemvura mhinduro.

2. Iyo yakakwira iyo yekudyira (kana kuiswa) kwe cellulose ether, iyo yakakwira iyo yekumonekwa kwayo yayo ine mvura. Nekudaro, teerera pakusarudza yakakodzera nguva yekudyara panguva yekushandisa kuti usanyanyisa kudya uye kukanganisa basa revhu uye yekongiri. mamirire.

3.Sezvimwe zvinwiwa zvakawanda, iyo visc77 ye cellulose ether solution inoderera nekuwedzera kupisa, uye nekukwirira kwekusangana kwe cellulose ether, yakakura iwo mhedzisiro yekushisa.

4. Hydroxypropyl methylcellulose solution inowanzo kuve muviri wepseudoplastic, uyo une pfuma yekuchekerera kuveura. Yakakura kuwanda kwekucheka panguva yekubvunzwa, inoderedza kuoneka. Naizvozvo, kubatana kwevhu kunoderera nekuda kwesimba rekunze, iro rinoenderana nekukwenenzvera kuvakwa kwedope, zvichikonzera kuti dhaka rive nekushanda kwakanaka uye kubatana.

Iyo hydroxypropyl methylcellulose mhinduro inoratidza hunhu hweNewtonia kana iyo yakasungwa iri shoma uye kuoneka kudiki. Kana iyo yekusunganidzwa yawedzera, mhinduro inogadzirisa zvishoma nezvishoma pseudoplastic fluid maitiro, uye yakanyanya kusangana, inova pachena pseudoplasticity.
