HPMC yeMasonry Mortars

HPMC, kana kuti hydroxypropyl methylcellulose, inoshandiswa zvakanyanya sechinhu chinowedzera mukugadzira masonry mortars. Aya madhaka anoshandiswa kubatanidza zvidhinha, matombo, uye mamwe masonry unit pamwe chete, achipa rutsigiro rwechimiro uye kugadzikana kune zvivakwa nezvimwe zvivakwa.

Imwe yeakakosha zvimiro zveHPMC inoita kuti ibatsire mumasonry dhaka kugona kwayo kuita seyakakora uye rheology modifier. Kuwedzerwa kweHPMC kune dhaka kunovandudza kushanda kwayo uye kupararira, zvichiita kuti zvive nyore kushandisa nekushanda nazvo. HPMC inovandudzawo kuwirirana uye kugadzikana kwedhaka, kuderedza njodzi yekudonha kana kudonha panguva yekushandisa.

Pamusoro pekukora kwayo zvivakwa, HPMC inoshandawo sebhainda uye firimu-inogadzira mumiriri mune masonry madhaka. Kuwedzerwa kweHPMC kune dhaka kunonatsiridza kunamatira kwayo kune substrate uye kune masonry units, kugadzira chisungo chakasimba uye chakasimba. HPMC inoumbawo firimu rinodzivirira pamusoro pedhaka, iro rinobatsira kudzivirira kubva kune mamiriro ekunze uye kukukurwa.

Imwe bhenefiti yekushandisa HPMC mumasonry mortars ndeyekuti inogona kubatsira kuderedza kunyura kwemvura mudhaka. Izvi zvakakosha nekuti kunyura kwemvura yakawandisa kunogona kukonzera kuderedzwa kwechimiro chechimiro, pamwe nekuwedzera njodzi yekuumbwa nekuvhuvhu.

HPMC inobatsirawo kune zvakatipoteredza. Iyo yakasikwa, inovandudzwa, uye biodegradable polymer iyo inotorwa kubva ku cellulose, iyo yakawanda muzvirimwa. Haisi-chepfu uye haisununguri zvinhu zvinokuvadza mumhepo.

kuwedzerwa kweHPMC kune masonry madhaka kunopa akati wandei mabhenefiti, kusanganisira kuvandudzwa kwekushanda, kunamatira, uye kusimba. HPMC inobatsirawo kuchengetedza dhaka kubva kumamiriro ekunze uye kukukurwa, uye inogona kuderedza kunyura kwemvura. Iyo zvakare inoshamwaridzana nemhoteredzo yekuwedzera.
