Doka chinhu chakakosha pakuvaka uye chinonyanya kushandiswa kusunga zvidhinha, matombo nemabhuroko ekongiri.HPMC (Hydroxypropylmethylcellulose) is an organic compound inoshandiswa sekuwedzera mune simende uye dhaka maumbirwo.Mumakore achangopfuura, HPMC yakakura mukuzivikanwa semusanganiswa wemakemikari mumadhaka uye kongiri.HPMC ine akati wandei akatanhamara zvivakwa zvinoita kuti ive sarudzo yakanaka kune akawanda ekuvaka zvinhu.Ichi chinyorwa chichakurukura nezvekuvandudza maitiro eHPMC dhaka pane kongiri.
Kuita kweHPMC Mortar
HPMC dhaka ine akawanda akanakisa zvivakwa uye inokurudzirwa zvakanyanya semusanganiswa wemakemikari mune zvekuvaka.HPMC imvura inonyungudika polima uye haizoite kana kubatana nezvimwe zvinhu mumusanganiswa.Ichi chivakwa chinowedzera purasitiki uye kushanda kwedhaka, zvichiita kuti zvive nyore kubata nekuisa.HPMC ine yakanakisa kunamatira kune akasiyana maficha, ayo anobatsira zvakanyanya pakuvandudza kusimba uye kusimba kwedhaka.HPMC inogadzirisa iyo hydration process yekongiri uye dhaka.Ichi chivakwa chinobvumira HPMC kushandiswa kudzora nguva yekumisikidza yemadhaka uye kuwedzera simba rekupedzisira rematokari.
Kuvandudza Mhedzisiro yeHPMC Mota paKongiri
Kuwedzera HPMC kune kongiri kune akawanda mabhenefiti ekupedzisira simba uye kusimba kwekongiri.HPMC inoderedza mvura-simende reshiyo, nokudaro kuderedza porosity kongiri uye kuwedzera simba rayo.Ichi chivakwa chinoita kuti chigadzirwa chekupedzisira chekongiri chiome uye chiomese kune zvekunze zvinhu zvakaita semamiriro ekunze uye kurwisa kwemakemikari.HPMC inowedzera purasitiki yedhaka, nekudaro ichivandudza kushanda kwekupedzisira kwekongiri uye kuwedzera nzira yekudurura.Iyo yekuwedzera kushanda inopihwa neHPMC zvakare inovimbisa zvirinani kufukidzwa kwekusimbisa mukongiri.
HPMC inoderedza huwandu hwemhepo yakavharirwa mukongiri, nekudaro ichideredza kutaridzika kwemapores uye mapeji muchigadzirwa chekupedzisira.Nekudzikisa huwandu hwema pores, simba rekumanikidza rekongiri rinowedzerwa, zvichiita kuti rive rakasimba uye rakasimba.Chechina, HPMC inovandudza kongiri hydration nekuda kwekugadzika kwayo uye kukora zvivakwa.Kuvandudzwa kwe hydration yekongiri kunoreva simba rakakura uye kusimba mune yekupedzisira chigadzirwa, ichichibvumira kutsungirira kune hukasha hwekunze zvinhu.
HPMC inobatsira kudzivirira kongiri kupatsanurwa.Kuparadzanisa ndiyo nzira iyo zvikamu zvekongiri zvinoparadzaniswa kubva kune mumwe nekuda kwemaitiro avo emuviri.Kuitika kwekuparadzanisa kunoderedza kunaka kwekupedzisira kwekrete uye kunoderedza simba rayo.Kuwedzerwa kweHPMC kune kongiri musanganiswa kunowedzera hukama pakati pezvikamu zvakasimba zvemusanganiswa wekongiri, nokudaro kudzivirira kupatsanurwa.
HPMC dhaka inoita basa rakakosha mukuvandudza simba rekupedzisira, kusimba uye kushanda kwekongiri.Mabhenefiti eHPMC muzvivakwa zvekuvaka ave achizivikanwa zvakanyanya uye zvakakonzera kushandiswa kwavo kwakapararira muzvirongwa zvekuvaka.Izvo zvakanakisa zvimiro zveHPMC zvinoita kuti iwedzere kukurudzirwa semusanganiswa wemakemikari mudhaka uye kongiri maumbirwo.Vavaki vanofanirwa kukoshesa kushandiswa kwematondo eHPMC mumapurojekiti avo ekuvaka kuti vawedzere kusimba uye kusimba kwechimiro chekupedzisira.
