HPMC, kana hydroxyprupyl methylcellose, chinhu chakakosha chinongedzo mumasimendi-based tile inonamira nekuda kwezvivakwa zvaro zvinowedzera mashandiro ezvekushandisa zve comentivent. Inoita senge sedhino, kudzora maitiro ekunamatira apo achivandudza kudenha kwayo uye kudzokorora kwemvura. Sezvo indasitiri yekuvaka ichiramba ichishanduka, HPMC yakawedzera kukosha mukusangana nezviyero zvakakwirira uye zvinodiwa zvekuvaka zvazvino maitiro.
Chimwe chezvikonzero zvikuru HPMC chinhu chakakosha chinongedzo mumasimendi-based tile majee its mishonga kwayo. HPMC iri mheremhere-soluble cellulose ether iyo inokara mhinduro kana yakawedzerwa mune zvidiki zvidiki. Izvi zvinopa chinonamatira chakakodzera kusimba, zvichiita kuti zvive nyore kushandisa nekuparadzira musanganiswa, pakupedzisira kugadzirisa basa uye kubereka. Kuvandudzwa kwekushanda zvakare kunobatsira kuderedza marara sezvo kuchitendera kusanganisa zviri nani uye kugoverwa kwezvinonamatira pamasikati. HPMC inoita seRheology modifier, inosimudza viscosity uye kudzivirira iyo inonamatira kubva mukununura zvakanyanya kana gobvu, iyo inogona kukanganisa maitiro ayo uye kukonzera kuiswa kusingaenzaniswi.
Chimwezve kubatsirwa kukuru kwekushandisa HPMC mumasimendi-yakavakirwa madhimoni anokanganisa kusimba kwesimba. HPMC iri yakanaka firimu yaimbova, zvichireva kuti inoumba denderedzwa rekudzivirira kutenderera kwechidimbu zvidimbu muBinder. Iyi denderedzwa inodzivirira inobatsira kudzivirira chisungo kubva mukuoma kunze kwekukurumidza, nekudaro nekuwedzera simba rekusungwa uye kusimba. Nenzira iyi, HPMC inobatsira kuwedzera nguva yekushanda yekunamatira uye inobvumira nguva yakakwana yemasikati kuti aiswe nenzira kwayo. Iyo yakasarudzika chisungo simba yakapihwa neHPMC zvakare inoderedza tile slipage, nekudaro ichivandudza huwandu hwakawanda hwekuisa tile.
Hpmc iri zvakare inozivikanwa elsififier inosimudzira nzvimbo yekuchengetwa kwemvura yekuchengetwa kwezvinoshambidza. HPMC inoonekwa nekugona kwayo kutora uye chengetedza mvura, ichiita kuti ive yakanaka yekukonzeresa coment-yakavakirwa madhimoni. Iko kuwedzera kwemvura-kubata-kubata kunopa chinonamatira chakakura kuderera, kuvandudza kunyoroveswa, uye kuwedzera chisungo ukobvu kune substrate. Mukuwedzera, HPMC inogona kugadzirisa mamiriro uye kuomesa maitiro ekunamatira kuitira kuti irege kutsungirira kushushikana kwekupfura nekuporesa. Izvi zvinobatsira kuvandudza kugona kwayo kwemvura, kuchengetedza mataira uye substrate kubva mukukuvara kwemvura uye kuendesa hupenyu hwegadziriro yekuisa pasi.
Imwe mukana yakakosha yekushandisa hpmc mumasimendi-yakavakirwa tile ainesomisheni ndeyekuenderana nezvimwe zvinoshandiswa. HPMC chinhu chinoita chinoshanda chinoshanda pamwe nemamwe macomputer-encucing zvakadai sekusavimbika so Lonsex polymers uye mapuroteri ekuvandudza kunaka uye kuita kwemaitiro emamiriro akasiyana uye mamiriro ezvinhu. Iko kushandiswa kweHPMC mumakwenzi anobvumidza kuita kwezvinoshambidza kuti kuve kwakarongedzwa kuti tisangane nezvinodiwa zvakasiyana zvemabasa akasiyana siyana emapurojekiti akasiyana mune chero mamiriro ezvinhu kana application.
HPMC chinhu chakakosha mumasimendi-based-based tiles inonamatira nekuti inovandudza musangano webasa, kuchengetwa kwemvura uye kushanda kwezvinonamatira. Inobatsira chero chirongwa chekuvaka nekupa kushanda kwakaringana, kuita kwakakwirira uye kudzivirirwa kwakanakisa kwesvina kubva mukukuvara kwemvura uye kupfeka. Zvakanakira HPMC dzinogona kuzadzikiswa nekuzvisanganisa nezvimwe zvinowedzera izvo zvinogadzirisa zvivakwa zvekunamatira kuti usangane nezvakanyanya basa. Naizvozvo, kushandiswa kweHPMC mumasimendi-yakavakirwa tile anoshongedza akakosha uye akachenjera sarudzo yekuvaka chero chirongwa chinoda mhando yepamusoro uye mhedzisiro isingaperi.
