HPMC for Waterproofing Motars

HPMC, kana kuti hydroxypropyl methylcellulose, inowanzoshandiswa mukugadzira dhaka rekudzivirira mvura. Mavhu ekudzivirira mvura anoshandiswa kugadzira chidziviriro chekudzivirira panzvimbo yekongiri, kudzivirira mvura kupinda mukati uye kukonzera kukanganisa.

Rimwe remabasa makuru eHPMC mumatope ekudzivirira mvura ndeyekuita 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 zvivakwa, HPMC inoshandawo sebhainda uye firimu-inogadzira mumiriri mumadhaka ekudzivirira mvura. Kuwedzerwa kweHPMC kune dhaka kunovandudza kunamatira kwayo kune substrate, kugadzira chisungo chakasimba uye chakasimba. HPMC inoumbawo firimu rinodzivirira pamusoro pedhaka, iro rinobatsira kudzivirira kubva kune mamiriro ekunze uye kukukurwa.

Imwe bhenefiti yekushandisa HPMC mumadhaka ekudzivirira mvura ndeyekuti inogona kubatsira kuvandudza dhaka rekudzivirira kumvura uye mwando. HPMC inogona kubata mvura mudhaka, iyo inobatsira kudzivirira mvura kuti isapinda pamusoro uye kukonzera kukanganisa. Izvi zvinogona kunyanya kukosha munzvimbo dzine njodzi huru yekupinza mvura, senge dzimba dzepasi uye zvimwe zviri pasi-giredhi maapplication.

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.

Pakazara, kuwedzerwa kweHPMC kune dhaka rekudzivirira mvura kunopa huwandu hwezvipo, zvinosanganisira kuvandudzwa kwekushanda, kunamatira, uye kuramba kumvura nehunyoro. HPMC inobatsirawo kuchengetedza dhaka kubva kumamiriro ekunze uye kukukurwa, uye inogona kuvandudza kusimba kwayo nekufamba kwenguva. Iyo zvakare inoshamwaridzana nemagariro ekuwedzera.
