HPMC, kana Hydroxypropyl Methyl Cellulose, chinhu chinobatika uye chakakosha chivakwa chakakura mukuzivikanwa mumakore achangopfuura.Sekubuda kwe cellulose, HPMC ine maapplication ekubva pazvizoro kusvika kune zvinonamira, uye zvakanyanya kukosha, yakawana nzira yayo muindasitiri yekuvaka seyakakora, inonamira, inodzivirira colloid, emulsifier uye stabilizer.
Kuvaka-giredhi HPMC imhando yepamusoro-soro, inonyungudika nemvura polima inoshandiswa mune dzakasiyana siyana zvigadzirwa zvesimende zvinosanganisira zvinonamira mataira, madhaka, plasters, grouts, uye ekunze insulation uye kupedza masisitimu (EIFS).Hunhu hwayo hwakasiyana-siyana hunoita kuti ive mhinduro yakakwana kune ese ari maviri ekuvaka uye ekugadzirisa mapurojekiti, sezvo ichiwedzera chisungo uye chisungo chemhando yemhando dzakasiyana siyana.
Imwe yemabhenefiti makuru eHPMC ndeye yakanakisa kuchengetedza mvura zvivakwa.Izvi zvinoreva kuti inogona kubatsira kuderedza huwandu hwemvura inodiwa kune zvigadzirwa zvesimende pasina kupira zvivakwa kana kushanda kwemusanganiswa.Nekuchengetedza unyoro, inodzivirira musanganiswa kubva pakuoma, kubatsira kuvandudza kunamatira uye kusimba kwechigadzirwa chekupedzisira.
Mukuwedzera, HPMC inoshanda sechidziviriro colloid, ichibatsira kuderedza njodzi yekuparadzanisa, kuputika uye shrinkage mune cementitious zvinhu.Izvi zvinoita kuti ive yakanakira yekuwedzera kune zvigadzirwa zvinoratidzwa kune yakaoma mamiriro ekunze kana kuti zvinoda kumira zvakanyanya kushushikana.
Pamusoro pezvivakwa izvi zvinosimudzira kuita, HPMC inozivikanwa zvakanyanya sechinhu chakasimba.Yakagadzirwa kubva kune zvinogonekazve zviwanikwa, ndeye biodegradable uye isiri-chepfu, izvo zvinoita kuti ive sarudzo yakakwana yezvakatipoteredza vanovaka uye makambani ekuvaka.
Sehumbowo hwekuita zvakasiyana-siyana, HPMC inoshandiswawo mukugadzira zvigadzirwa zvegypsum-based senge stucco uye majoini makomisheni.Muchiitiko ichi, HPMC inobatsira kuvandudza kushanda uye kuenderana kwemusanganiswa, ukuwo ichiwedzera chisungo chesimba pakati pestucco uye substrate.
Architectural giredhi HPMC inowanikwa muakasiyana maviscosities uye particle saizi, achibvumira izvo zvinhu kuti zvigadziriswe kune chaiyo chigadzirwa zvinodiwa.Izvi zvinoita kuti zvive zvakanyanya kuchinjika zvinhu zvinogona kushandiswa mumhando dzakasiyana dzekushandisa uye nharaunda.
Mukupedzisa, HPMC chinhu chakakosha kuindasitiri yekuvaka uye maitiro ayo akanaka akawanda.Iine yakanakisa kuchengetedza kwemvura, inodzivirira colloid uye inosimudzira zvivakwa, inogoneka uye yakakosha yekuwedzera kune chero chigadzirwa chekuvaka.Inovandudza mashandiro, inoderedza marara uye yakanakira vavaki vanongwarira zvakatipoteredza uye makambani ekuvaka.Kushandiswa kweHPMC kuri kujekesa ramangwana reindasitiri yekuvaka.
