hydroxypypyl methylcellulose(Hpmc)ndi polima polymer omwe amagwiritsidwa ntchito kwambiri pomanga kuti asinthane ndi zinthu za simenti. Maudindo ake oyamba amaphatikiza kukonzanso kugwirira ntchito, kusungidwa kwamadzi, kutsatira, ndikukhazikitsa nthawi. Chiwerengero cha Kimacell®hpmc ku simenti ndi gawo lovuta lomwe limapangitsa kuti ntchito ziziphatikiza.
Gome la General la HPMC ku CEMERS RATIOS
| Hpmc to cement ratio (%) | Zotsatira za katundu | Mapulogalamu |
| 0.1 - 0.3% | Kusintha pang'ono pakusungidwa kwamadzi komanso kugwirira ntchito. Zovuta zochepa pa mphamvu. | General Manider. |
| 0.4 - 0.6% | Kutsatira mokweza, kusungidwa kwamadzi, komanso kusasinthika. Kuchedwa pang'ono pokha. | Zilonda za Tile, zopota zoyambirira. |
| 0.7 - 1.0% | Kuwonjezeka kwakukulu kwamadzi kusungidwa ndi kugwirira ntchito. Kuchedwa mu nthawi yakwana kumawoneka. | Zomata zowonda-bed, mankhwala odzikongoletsa okha. |
| 1.1 - 1.5% | Kusungidwa kwamadzi kwakukulu. Kuwongolera kokhazikika mu kugwirira ntchito, kugwirira ntchito, ndi kutsatira. Kuchedwa Kuchepa. | Malaya a Skim, matope oyendetsa bongo. |
| > 1.5% | Kusungidwa kwamadzi kwambiri komanso kuchedwa kwambiri kuchedwa. Chiopsezo chochepetsa mphamvu. | Matope opangidwa ndi nthawi yayitali yogwira ntchito. |
Kufotokozera mwatsatanetsatane kwa radios
Ma ratios otsika (0.1 - 0.3%)
Ubwino:
Amasintha katundu wosakhazikika popanda kusintha zinthu.
Oyenera kusintha kwa simenti yokhazikika yochokera pakufunika kochepa kuti asinthe.
Zoperewera:
Kuchepetsa malire pa kusungidwa kwamadzi mu gawo lokongola kwambiri.
Makina othamanga (0.4 - 0.6%)
Ubwino:
Kusunga kwamadzi koyenera komanso kugwirira ntchito kovuta kwambiri.
Zabwino kwa zochitika zomwe zimafunikira kutsatira zotsatsa zoyambira.
Zoperewera:
Kuchepa kochepa kumatha kuchitika, ngakhale nthawi zambiri nthawi zambiri zimatha.
Ma ratios apamwamba (0.7 - 1.5%)
Ubwino:
Imagwiritsa ntchito njira yabwino yosungira madzi komanso yosalala, yochepetsera youma youma.
Amakonda kugwiritsa ntchito mapulogalamu owonda-woonda amafuna kulondola.
Zoperewera:
Pamafunika kuwongolera mosamala kuti mupewe kuchedwa kwambiri kuchedwa, komwe kumatha kukhudza ndalama za polojekiti.
Zowonjezera zowonjezera (> 1.5%)
Ubwino:
Imathandizira kusungidwa kwamadzi kwambiri kwambiri komanso nthawi yayitali yotseguka.
Zothandiza kwa niche kapena chilengedwe.
Zoperewera:
Ikhoza kunyengerera mphamvu yamakina yomaliza ngati sipangapangidwe mosamala.
Zosangalatsa Kusankhidwa kwa Ratio
Mtundu Wofunsira:
Otsatsa:Amafunikira ma ratios apamwamba kuti apititse mphamvu ndikupewera kutsika.
Matope:Makina othamanga amaonetsetsa kuti ndi othandiza komanso nthawi yokwanira yothira.
Zinthu Zachilengedwe:
Kutentha kwambiri kapena minda yamkuntho nthawi zambiri kumayenera kusintha kuchuluka kwa HPMC kuti musungidwe kwamadzi abwino.
Mtundu wa simenti:
Nyimbo zosiyanasiyana za simenti zitha kuchitira mosiyanasiyana ndi Kimacell®hpmc, imapangitsa kuti magawo okwanira.
Kuyerekeza:
Kugwirizana ndi zina zowonjezera (mwachitsanzo, ogulitsa kapena othamanga) ayenera kuganiziridwa.
Kugwiritsa ntchito gawo loyenera laHpmckwa simenti ndikofunikira kuti mukwaniritse ntchito zomanga. Ngakhale kuchuluka kotsika kumapereka kukonzanso kwapadera, ma ratios apamwamba amagwirizanitsidwa pamapulogalamu apadera. Komabe, kugwiritsidwa ntchito kwambiri kumatha kuchepetsedwa kuchepetsedwa mphamvu yamakina ndikusintha nthawi yomwe itakhala, kufunikira njira yoyenera. Kufufuza kwina komanso kuyesa kwa tsamba kumalimbikitsidwa kuti ntchito zamagulu azikhala ndi zotsatira zabwino.
