HydroxyPropyl methylcellose (HPMC) is is is is is-ionic, yemvura-yemvura polymer inotorwa kubva ku cellulose, inosanganisira maindasitiri akasiyana-siyana, kusanganisira mishonga yemishonga, chikafu, uye kuvaka. Muchirevo cheiyo coment-based griuth, HPMC inoshanda mabasa akati wandei idzo dzinowedzera kuita uye kushanda kwegorofu.
1. Rheology shanduko
HPMC zvakanyanya kugadziridza zvivakwa zvetsiva zvemasimende-yakavakirwa. Rheology inoreva kuyerera kwemaitiro emusanganiswa wegombwe, izvo zvakakosha kuti zvikumbiro zvinoda chaizvo kudzora pamusoro pegreut kusawirirana uye kushanda. Nekuwedzera HPMC, iyo viscosity yeGrout inogona kugadziriswa, kubvumira kupomba kuri nyore uye kushandisa. Izvi zvinonyanya kukosha kuti grouts dzinoshandiswa munzvimbo dzakaoma kuwana kana kuda nzira dzekuisa nzvimbo.
Viscosity Kuwedzera: HPMC inowedzera iyo visikoka yeiyo grout, kudzivirira kusarongeka kwezvinhu uye kuona musanganiswa weunifomu. Ichi chivakwa chinobatsira kuchengetedza iyo homogeneity yegrout panguva yekushandisa.
Thiskotropy: Iyo thiskitropic yemasikati yeHPMC-yakagadziriswa nzira dzinogona kuve dzishoma viscous pasi pekushushikana (semuenzaniso, panguva yekupomba) asi tangazve visikoka kana kushushikana kana kunetseka kwavo kwabviswa. Maitiro aya anobatsira mukuchengetedza chimiro uye kugadzikana kweiyo grout mushure mekuiswa.
2. Kuchengeta mvura
Imwe yemabasa akakosha eHPMC mumasimendi-yakavakirwa grout ndeyekugona kuita kuwedzeredza kuchengetwa kwemvura. SEment hydration, maitiro emakemikari anopa siment simba rayo, anoda huwandu hwakaringana hwemvura. HPMC inobatsira mukuchengetedza mvura mukati memusanganiswa wekuremera, izvo zvinotungamira kune dzinoverengeka zvakanaka:
Kuvandudzwa Hydration: Nzira inovimbisa kuti mvura yakawanda iripo yeiyo hydration maitiro, inotungamira kune iri nani kuporesa uye kusimbisa simba.
Kuderedza kubuda ropa uye kutsikisa kwemvura kunobatsira mukudzora kubuda ropa (kumusoro kwekufamba kwemvura) uye kusarudzika (kupatsanurana kwezvikamu) kwegorofu, kusimbisa musanganiswa unowirirana uye hwakagadzikana.
3. Kubata uye kushanda kwekushandisa
HPMC inovandudza basa rekushanda kweiyo cement-yakavakirwa grout, kuita kuti vave nyore kusanganisa, pombi, uye shandisa. Izvi zvinonyanya kukosha mukuvaka mamiriro ezvinhu uko kugona kwekushandisa kunogona kukanganisa chirongwa chemufananidzo wese uye mhando.
Kurerutsa kwekusanganisa: HPMC-yakagadziridzwa grouts iri nyore kusanganisa, zvichikonzerwa mune imwe musanganiswa we homogeness pasina clumps kana kusagoverwa zvisina kujairika kwezvinhu.
Kubata kwehunyanzvi: Iyo yakavandudzwa viscosity uye thiskitropic zvivakwa
Kudzora Kwekushandisa: Kubatikana Kurovedzera kunobvumidza kutonga kuri nani panguva yekushandisa, kuona kuti grout inozadza voids uye marara zvizere uye zvinonamatira zvakanaka kune substrate.
4. Adhisheni uye kusungwa
HPMC inovandudza iyo yakanamatira zvivakwa zve coment-based grouts. Izvi zvakakosha kuti uve nechokwadi chekuti zvisungo zvegoriyamu zvinobudirira kunzvimbo dzinotsvedza izvo zvinoshandiswa kune, kungave kuri mune zvigadzirwa zvekugadzirisa, kuronga, kana kuisirwa kuiswa.
Kuwedzera Bond Simba: Kuwedzera kweHPMC kunowedzera zvivakwa zvekunamatira kwekutenderera, zvichikonzera chisungo chakasimba pakati pegrout uye substrate.
Kuvandudzwa Durability: Yakavandudzwa ADhisheni inobatsira mukuvimbika kwekusimba uye hurefu hwekuvakwa, sekushungurudzika kwacho kushoma kushoma kana kusvibisa nekufamba kwenguva.
5. Kupisa kuramba uye kusimba
Kubatanidzwa kweHPMC mumapundu-yakavakirwa magirazi anowedzerawo kupokana nekupaza uye kunovandudza kusimba kwayo kwenguva refu. Izvi zvinowanikwa kuburikidza neinotevera michina:
Drinkage kuderedza: HPMC inobatsira mukuderedza kuderera kweiyo grout sezvo ichirapa. Shrinkage chiitiko chakajairika chekupaza mumasimendi-based zvinhu, uye nekuderedza, HPMC inobatsira mukuvimbika kwese kwechimiro.
Kuchinjika Kugadziridzwa: Iyo Polymeric yakasikwa yeHPMC inopa degree rekushanduka kweiyo grout, uchibvumira kuti ugone kugadzirisa zvizere uye zvichimanikidza kushushikana pasina kupaza.
6. Zvakanakira zvehupfumi
Uchishandisa HPMC mumapundu-yakavakirwa grout inogona zvakare kupa zvakanakira zvezvakatipoteredza uye zvehupfumi. Yakavandudzika kushanda uye yakaderedzwa marara inotungamira kushandiswa kwakanyatsoshanda kwezvinhu zvekushandisa uye basa.
Kubudirira kwezvinhu: Zvivakwa zvinowedzerwa zvakapihwa neHPMC zvinoreva kuti zvishoma zvinhu zvinogona kudikanwa kuti uwane kuita kwaunoda kuita, kuderedza kushandiswa kwese kwezvinhu.
Kugadziriswa kugadziriswa uye kugadzirisa: Kugadziriswa kweHPMC-yakagadziridzwa grouts kunotungamira kune mashoma ekugadzirisa uye kugadziriswa pamusoro pehupenyu hwechimiro, chinokonzerwa nemutengo murefu mari yekuchengetedza.
Kuwedzerwa kwehydroxyprishpropyl methylcellose (HPMC) kusvika kumasimendi-based guguts anoita basa rakawanda mukuvandudza kwavo kuita uye kushanda. Nekugadziridza zvivakwa, kuvandudza kudzokorora kwemvura, kusimudzira mvura yekuvandudza, kuwedzera kusanganisa kuramba uye kusimba, HPMC inovimbisa kuti groumende-yakavakirwa grout inosangana nezvinodiwa zvezvirongwa zvazvino zvekuvaka. Uyezve, mabhenefiti ehupfumi uye ehupfumi anosimbisa kukosha kweHPMC seinokosha anowedzera muindasitiri yekuvaka. Sezvo nzira dzekuvaka uye zvigadzirwa zvinoramba zvichishanduka, basa reHPMC mumapundu-yakavakirwa giredhi ingangodaro ichiramba ichikonzeresa kukwana kwemhando yepamusoro, yekuvaka yekuvaka.
