hydroxypropyl methylcellulose(I-HPMC)Ingabe i-polymer yokwenziwa esetshenziswa kabanzi ekwakheni ukuguqula izakhiwo zezinto zokwenziwa kosimende. Izindima zalo eziphambili zifaka ukuthuthukisa ukusebenziseka, ukugcinwa kwamanzi, ukunamathela, nokubeka isikhathi. Isilinganiso se-Kimacell®HPMC eya ku-Conment iyipharamitha ebucayi ethonya kakhulu ukusebenza kwengxube.
Ithebula Elijwayelekile le-HPMC liye kwisilinganiso sokwenza usimende
| I-HPMC iye kwisilinganiso sikasimende (%) | Umphumela Kwezakhiwo | Izinja |
| 0.1 - 0.3% | Ukuthuthuka okuncane ekugcinweni kwamanzi nasekusebenzeni. Umthelela omncane kumandla. | General Masonry Masonry. |
| 0.4 - 0.6% | Ukutholwa okuthuthukile, ukugcinwa kwamanzi, kanye nokuvumelana. Ukubambezeleka okuncane kokusetha isikhathi. | Ama-tile anamathela, ukulungiswa okuyisisekelo. |
| I-0.7 - 1.0% | Ukwanda okukhulu kokugcinwa kwamanzi nokusebenza. Ukubambezeleka kokusetha isikhathi kungabonakala. | Adhesives anciphisiwe embhedeni, amakhompiyutha azimisele. |
| 1.1 - 1.5% | Ukugcinwa kwamanzi okuphezulu. Ukuthuthuka okumakwe ekusebenzeni, ukuhlangana, kanye nokunamathela. Kwenzeke ukubambezeleka kwenzeka. | Ama-Skim Coats, ohulumeni abasebenza kahle. |
| > 1.5% | Ukugcinwa kwamanzi ngokweqile kanye nokubambezeleka okubalulekile ekuhlelweni. Ubungozi bokuncipha kwamandla okwenziwayo. | Uhlobo olukhethekile oludinga isikhathi esengeziwe sokusebenza. |
Ukuchazwa okuningiliziwe kwezilinganiso ezibalulekile
Izilinganiso eziphansi (0.1 - 0.3%)
Izinzuzo:
Kuthuthukisa izakhiwo eziyisisekelo ngaphandle kokuguqula ngokwezinto ezibonakalayo.
Ilungele ukuxubeka okusezingeni eliphansi komoya ngesidingo esincane sokuguqulwa.
Ukulinganiselwa:
Umthelela olinganiselwe ekugcinweni kwamanzi ezindaweni ezifundwayo kakhulu.
Izilinganiso ezilinganiselayo (0.4 - 0.6%)
Izinzuzo:
Izilinganiso zokugcinwa kwamanzi nokusebenza kwezicelo ezifunwa kakhulu.
Ilungele izimo ezidinga ukunamathela okuthuthukile ku-substrates.
Ukulinganiselwa:
Ukubambezeleka okuncane kokusetha kungenzeka, yize kuvame ukuphatha.
Izilinganiso eziphakeme (0.7 - 1.5%)
Izinzuzo:
Inikeza ukugcinwa kwamanzi okuhle nokusetshenziswa okubushelelezi, ukunciphisa ukumiswa kwe-shrinkage.
Kukhethwe izinhlelo zokusebenza eziphansi ezidinga ukunemba.
Ukulinganiselwa:
Kudinga ukulawula ngokucophelela ukugwema ukubambezeleka ngokweqile kokuhlehlisa, okungathinta ama-timo wephrojekthi.
Izilinganiso Eziqile (> 1.5%)
Izinzuzo:
Ilungiselela ukugcinwa kwamanzi okuphezulu kanye nezikhathi ezivulekile ezivulekile.
Ilusizo kwi-niche noma izimo zemvelo ngokweqile.
Ukulinganiselwa:
Kungahlehlisa amandla emishini yomkhiqizo wokugcina uma kungenjalo ukunakekelwa ngokucophelela.
Izici Ukuthonya Ukukhetha Kwe-Ratio
Uhlobo lwesicelo:
Adhesives:Dinga isilinganiso esiphakeme ukuthuthukisa amandla e-bond futhi uvikele ukucwila.
Udaka:Izilinganiso ezilinganiselayo ziqinisekisa ukusebenziseka okuhle nokuvuka ngokwanele.
Izimo zemvelo:
Amazinga okushisa aphezulu noma izimo ezinomoya zivame ukudinga isilinganiso esiphakeme se-HPMC sokugcinwa kwamanzi okungcono.
Uhlobo lwesimende:
Izingoma ezihlukene usimende zingasabela ngendlela ehlukile nge-Kimacell®HPMC, zithonya izilinganiso ezifanele.
Ukuhambisana okungeziwe:
Ukusebenzisana nezinye izengezo (isib, retaarders noma ama-accelerators) kumele abhekwe.
Usebenzisa isilinganiso esifanele seI-HPMCKusimende kubalulekile ekusebenzeni kahle kwezinto zokwakha. Ngenkathi izilinganiso eziphansi zihlinzeka ngentuthuko eyisisekelo, isilinganiso esiphakeme senzelwe izinhlelo zokusebenza ezikhethekile. Ukusetshenziswa ngokweqile, noma kunjalo, kungaholela ekunciphiseni amandla okunciphisa kanye nezikhathi zokubeka, kudinga indlela elinganiselayo. Ukuqhubeka kokucwaninga nokuhlolwa okuku-site kunconyelwe amaphrojekthi athile ukuqinisekisa imiphumela emihle kakhulu.
