Cellulose HPMC, inozivikanwawo se hydroxypropyl methylcellulose, chinhu chinovandudzwa uye chine hushamwari hwezvakatipoteredza chinobva muselulosi kubva muhuni pulp kana donje faibha.Iyo nonionic polymer ine yakanakisa kuchengetedza mvura, kukora, uye firimu-kugadzira zvivakwa.Inoshandiswa zvakanyanya mumaindasitiri akasiyana akadai sekuvaka, mushonga, chikafu, zvizorwa, uye machira.
Muindasitiri yekuvaka, HPMC inonyanya kushandiswa seye rheology modifier uye mvura inochengetedza mumiriri mune simende-based zvigadzirwa senge madhaka, grouts, mataira anonamira uye ega-leveling makomisheni.Inoita basa rakakosha mukuvandudza kugadzirisika, kusimba uye kuita kwezvishandiso izvi, kuve nechokwadi chekuenderana uye fungidziro yemhedzisiro.
Imwe yemabhenefiti akanyanya kukosha emhando yepamusoro cellulose HPMC kugona kwayo kuenzana uye zvinobudirira kuparadzirwa mumatope esimende uye gypsum matrix zvigadzirwa.Izvi zvinokonzerwa nekugadzirwa kwayo kwakasiyana-siyana kwemakemikari, izvo zvinoita kuti ienderane neizvi mineral-based materials uye inobvumira kuti iite yakagadzikana, yunifomu dispersions.
Kana yawedzerwa kudhaka resimende kana gypsum matrix, HPMC inoumba chidziviriro chakatenderedza zvimedu, zvichidzidzivirira kubva pakudonha kana kugadzika.Izvi zvinoguma mune imwe homogeneous, nyore-kubata-musanganiswa, kuderedza dambudziko rekuparadzana nekuvandudza kuwirirana uye kunaka kwechigadzirwa chekupedzisira.
Uyezve, iyo inochengetedza mvura yeHPMC inogonesa kuchengetedza unyoro mukati me matrix, ichisimudzira kwakaringana hydration yemasimende masimende uye kuwedzera chisungo kusimba uye kusimba pakati pavo.Izvi zvinonyanya kukosha munzvimbo dzakaomarara dzezvakatipoteredza apo zvinhu zvinogona kuoneswa kune chando-thaw kutenderera kana hunyoro hwepamusoro, zvichikonzera kutsemuka, spalling kana delamination.
Pamusoro peiyo rheological uye yekuchengetedza mvura mabhenefiti, HPMC inoita seyakakora uye bhainda kune zvigadzirwa zvine simende, ichipa kugadzikana kukuru uye kunamatira.Inonatsiridza kusagadzika kwematairi anonamira, inodzivirira kubuda ropa kweanozvigadzirisa makomisheni uye inosimudzira kusimba kwechisungo chepurasita kana plaster.
HPMC chinhu chisiri chepfu uye chinoparadza, zvichiita kuti ive yakanakira maitiro ekuvaka akasimba.Hapana maVOC anokuvadza kana zvinosvibisa zvinoburitswa panguva yekugadzirwa kana kushandiswa, uye zvinogona kuraswa zvakachengeteka mushure mekushandisa.
Yepamusoro-mhando cellulose HPMC chinhu chakasiyana-siyana uye chakakosha kuindasitiri yekuvaka, inosimudzira mashandiro uye kuvimbika kwezvigadzirwa zvesimende.Kugona kwayo kuparadzira zvakaenzana uye zvinobudirira mukati medhaka uye plaster matrices, pamwe chete nekuchengetedza kwayo mvura, kukora uye kusunga zvivakwa, inoita kuti ive chinhu chakakosha kune chero chirongwa chekuvaka.
Kugadzikana kwayo uye eco-hushamwari kunoita kuti ive sarudzo ine mutoro kune vavaki nevagadziri vanoisa pamberi pekuchengetedzwa kwezvakatipoteredza uye mutoro wemagariro.Naizvozvo, chinhu chinofanirwa kuzivikanwa zvakanyanya uye kushandiswa kusimudzira indasitiri yekuvaka uye nepasi rose.
