Cellulose Eteri HPMC Kuvaka Giredhi yeWall Putties

Cellulose ether HPMC (Hydroxypropylmethylcellulose) inowanzoshandiswa sechinhu chakakosha chekuwedzera mumadziro putty formulations. Wall putty isimbi inoiswa kumadziro emukati uye ekunze kuti ipe yakatsetseka, kunyange pamusoro pepende kana Wallpaper. HPMC inovandudza akati wandei emadziro putty, ichibatsira kusimudzira kuita kwayo uye maitiro ekushandisa. Heano mamwe emabasa akakosha anotambwa neHPMC mukuvaka giredhi madziro putties:

Kuchengetedzwa kwemvura: HPMC inoshanda seyekuchengetedza mvura uye inobatsira kudzora hunyoro hwemukati muputty panguva yekurapa. Inodzivirira kuomeswa nekukurumidza uye inova nechokwadi che hydration yakakwana ye simenti, ichikurudzira kurapa kwakakodzera uye kukura kwesimba.

Kushanda uye kupararira: HPMC inowedzera kushanda uye kupararira kwemadziro putty, zvichiita kuti zvive nyore kusanganisa, kuisa uye kupararira pamusoro. Inopa kuwirirana kwekrimu uye inovandudza kuyerera kwezvinhu, kufambisa kushandiswa kwakatsetseka uye kuderedza kushanda kunodiwa panguva yekukwenya.

Adhesion: HPMC inonatsiridza kunamatira kwemadziro putties kune akasiyana substrates sekongiri, plaster kana masonry nzvimbo. Iyo inosimudzira kusimba kwechisungo uye inoderedza mukana we delamination kana peeling nekufamba kwenguva.

Crack kuramba: Kuwedzerwa kweHPMC kunobatsira kuvandudza kutsemuka kuramba kwemadziro putty. Iyo inoderedza shrinkage uye inoderedza kuputika kuumbwa nekuda kwekuoma kana kufamba kwekupisa. Ichi chivakwa chinowedzera kusimba kweputty uye chinobatsira kuchengetedza nzvimbo isina musono.

Sag Resistance: HPMC inobatsira kune sag kuramba kwemadziro putties kana yaiswa kune yakatwasuka nzvimbo. Iyo inobatsira iyo putty kuchengetedza chimiro chayo uye inodzivirira yakawandisa deformation kana kudonha panguva yekuvaka, kuve nechokwadi kuenzana kwemadziro ukobvu.

Yakavhurika Nguva: HPMC inowedzera iyo yakavhurika nguva yemadziro putty, iyo inoreva iyo nguva iyo zvinhu zvinoramba zvichishandiswa mushure mekusanganiswa. Inobvumira hwindo rekushandisa refu uye rinonyanya kubatsira pakushanda munzvimbo dzakakura kana pasi pemamiriro ekushisa.

Iwo chaiwo huwandu hweHPMC hunoshandiswa mumadziro putty hunoenderana nezvinhu zvakaita sekuenderana kwaunoda, mamiriro ekunze uye chaiyo chigadzirwa magadzirirwo. Vagadziri vegiredhi rekuvaka HPMC vanowanzopa nhungamiro uye kurudziro yekuibatanidza mumadziro putty masisitimu. Zvinokurudzirwa kuti uedze zvinoenderana nemirairo yemugadziri kuti uwane kuita kunodiwa uye kunaka kwemadziro putty.
