Basa rehydroxypropyl methyl cellulose mukudzivirira kupararira kwemamortar akavakirwa nesimende
Hydroxypropyl Methylcellulose (HPMC) chinhu chinowanzo shandiswa mumamota akagadzirwa nesimende. Mamota anoshandiswa mumabasa akasiyana-siyana ekuvaka akadai semadziro ekuvaka, pasi, nezvimwe zvinhu zvekuvaka. Hunhu hwemota hunoita basa rakakosha mukugara kwenguva refu uye kuramba kwezvivakwa izvi kumamiriro ekunze nezvimwe zvinhu zvekunze. HPMC yakaonekwa kuti inowedzera zvakanyanya kuramba kwemota dzakagadzirwa nesimende. Pepa iri richaongorora basa reHPMC mukurambira kwemota dzakagadzirwa nesimende.
Chii chinonzi kuramba kupararira?
Kuramba kupararira kwesimbi ndiko kugona kwesimbi kuchengetedza chimiro chayo uye kusimba kwayo kana yaiswa mumvura. Kunyangwe zvichikosha kuti simbi ipinde mumvura kuitira kuti ikwanise kufema, zvakakoshawo kuti simbi isashaye simba kana kutanga kunyunguduka kana yasangana nemvura. Kuramba kupararira kwesimbi dzakagadzirwa nesimende chinhu chakakosha kuti simbi dzigare kwenguva refu muzvivakwa.
Basa reHPMC mukudzivirira kupararira kwemvura
HPMC inoshandiswa zvakanyanya sechinhu chinowedzera simba muzvimedu zvesimbi zvakagadzirwa nesimende kuti zvivandudze simba razvo rekudzivirira kupararira..HPMC inoshanda sechinobatanidza nekugadzira membrane pakati pezvimedu zvesimbi, izvo zvinopa chipingamupinyi pamvura..Firimu iyi inowedzera simba rekubatana kwesimbi, zvichiita kuti irambe yakasimba panguva yekusangana nemvura. Pamusoro pezvo, HPMC inovandudza kushanda kwesimbi nekuderedza huwandu hwemvura, zvichiita kuti ive yakakora uye yakamanikana..Izvi zvinoita kuti simbi irambe yakasimba inopa simba rekudzivirira kupararira..HPMC inoshandawo sechinochengetedza mvura nekuderedza kurasikirwa kwemvura kubva mumusanganiswa panguva yekushandiswa, zvichikonzera kusimba kwesimbi zviri nani. Uyezve, HPMC inowedzera simba remuchina wesimbi nekuvandudza simba rayo rekunamatira..Firimu rinoumbwa neHPMC pakati pezvimedu zvesimbi rinovandudzawo kubatana pakati pesimbi nesubstrate, zvichikonzera kubatana kuri nani.
Mhedziso:
Mukupedzisa, Hydroxypropyl Methylcellulose (HPMC) chinhu chakakosha mukuvandudza kuramba kupararira kwemamortar akavakirwa pasement. HPMC inoshanda sechinobatanidza, chinhu chinochengetedza mvura, uye inowedzera simba remuchina wemortar uku ichivandudza kushanda kwayo. Firimu rekudzivirira rinoumbwa neHPMC pakati pezvikamu zvesimende rinowedzera kubatana kwemortar, zvichiita kuti irambe yakasimba kana yasangana nemvura.. Kushandiswa kweHPMC mumamortar akavakirwa pasement inzira inodhura uye inoshanda yekuvandudza kugara kwenguva refu kwechimiro uye kuramba mamiriro ekunze.
