Ibasa rei iro cellulose ether inoita muindasitiri yekuvaka?

Cellulose ether, yakadai seHydroxypropyl Methyl Cellulose (HPMC) uye Methyl Hydroxyethyl Cellulose (MHEC), inoita basa rakakosha muindasitiri yekuvaka. Aya ma cellulose anobva kune anoshandiswa zvakanyanya sekuwedzera mune zvakasiyana siyana zvekuvaka nekuda kwezvakasiyana zvivakwa uye zvakanakira.

Cellulose ether ipolymer yechisikigo inotorwa kubva kunatsiridza donje linter, inova chikamu chikuru chechirimwa masero madziro. Muchikamu chekuvaka, anonyanya kushandiswa seakobvu, anonamira, ekuchengetedza mvura uye rheology modifiers mune simende-based zvigadzirwa senge madhaka, plasters uye mataira anonamira. Izvi zvinowedzera zvinovandudza kushanda, kunamatira uye kuwirirana kwezvinhu zvekuvaka, nokudaro zvichivandudza kushanda uye kusimba kwechimiro chekupedzisira.

Rimwe remabasa akakosha e cellulose ether mukuvaka kugona kwavo kuvandudza kuchengetwa kwemvura kwesementitious misanganiswa. Izvi zvakakosha kudzivirira mvura kuti irege kukurumidza kubuda kubva mudhaka nyowani kana kongiri, izvo zvinogona kutungamirira mukutsemuka uye kurasikirwa kwesimba. Nekuchengetedza mvura mumusanganiswa, cellulose ether inobatsira kune zvirinani hydration yemasimende, nekudaro inovandudza huwandu hwese hwezvinhu zvakaomeswa.

Pamusoro pezvo, cellulose ether inoshanda seyakagwinya inoshanda, kuve nechokwadi chekuti zvigadzirwa zvekuvaka zvine kuenderana kwakakodzera uye zviri nyore kushandisa. Ivo zvakare vanosimudzira kubatana uye kunamatira kwemateki uye zvinopa, kusimudzira zvirinani kusungirira kune substrate uye kuderedza njodzi yeku delamination kana kutadza.

Pamusoro pezvavakanakira zvekushanda, cellulose ether inobatsirawo pakusimba kwemaitiro ekuvaka. Semapolymers echisikigo uye anovandudzwa, vanopa imwe yenzvimbo ine hushamwari kune zvekugadzira zvekuwedzera, zvinoenderana nekukura kwekusimbisa pazvinhu zvakasvibirira zvekuvaka uye maitiro.

Pakazere, cellulose ether yakadai seHPMC neMHEC inoita basa rakakosha mukuvaka kwemazuva ano nekuvandudza mashandiro, kugadzirisa uye kusimba kwezvinhu zvakasiyana zvekuvaka. Kushandiswa kwavo kwakasiyana-siyana uye kunaka kwakanaka pakuita kwezvigadzirwa zvekuvaka kunoita kuti zvive zvekuwedzera zvakanyanya muindasitiri. Sezvo maitiro ekuvaka achienderera mberi nekushanduka, cellulose ethers inotarisirwa kuramba iri chikamu chakakosha mukuvandudzwa kwemhando yepamusoro uye yakagadzikana zvivakwa.
