Kuma-kuvanga minisiteri (DMM) ni ibikoresho byubaka byifu byakozwe no kumisha no kumenagura sima, gypsumu, lime, nibindi nkibikoresho fatizo byingenzi, nyuma yo kubigereranya neza, ukongeramo inyongeramusaruro zitandukanye zuzuza. Ifite ibyiza byo kuvanga byoroshye, kubaka byoroshye, hamwe nubwiza buhamye, kandi bikoreshwa cyane mubwubatsi, ubwubatsi bwo gushushanya nibindi bice. Ibyingenzi byingenzi byumye-kuvanga minisiteri harimo ibikoresho fatizo, ibyuzuza, ibivanze ninyongera. Muri bo,selile ether, nk'inyongera y'ingenzi, igira uruhare runini mugutunganya imvugo no kunoza imikorere yubwubatsi.
1. Ibikoresho shingiro
Ibikoresho shingiro nigice cyingenzi cya minisiteri yumye, mubisanzwe harimo sima, gypsumu, lime, nibindi. Ubwiza bwibikoresho fatizo bigira ingaruka ku buryo butaziguye imbaraga, gufatana, kuramba hamwe nibindi bintu bya minisiteri yumye.
Isima: Nibimwe mubikoresho fatizo bikunze kugaragara mumashanyarazi yumye, mubisanzwe sima ya silikate isanzwe cyangwa sima yahinduwe. Ubwiza bwa sima bugena imbaraga za minisiteri. Ibyiciro bisanzwe byingufu ni 32.5, 42.5, nibindi
Gypsumu: ikoreshwa cyane mugukora pompe ya pompe na minisiteri idasanzwe yo kubaka. Irashobora gutanga umusaruro mwiza no gukomera mugihe cyogutanga amazi no kunoza imikorere ya minisiteri.
Lime: mubisanzwe bikoreshwa mugutegura bimwe bidasanzwe, nka lime. Gukoresha lime birashobora kongera amazi ya minisiteri no kunoza ubukonje bwayo.
2. Uzuza
Uzuza bivuga ifu ya organic organique ikoreshwa muguhindura imiterere yumubiri wa minisiteri, mubisanzwe harimo umucanga mwiza, ifu ya quartz, kwaguka perlite, ceramsite yagutse, nibindi. Igikorwa cyuzuza ni ugutanga ingano ya minisiteri no kugenzura amazi yayo no gufatira hamwe.
Umusenyi mwiza: ukunze gukoreshwa mumashanyarazi asanzwe yumye, hamwe nubunini buto, mubisanzwe munsi ya 0.5mm.
Ifu ya Quartz: nziza cyane, ikwiranye na minisiteri isaba imbaraga nyinshi kandi ziramba.
Kwagura perlite / kwaguka ceramsite: bikunze gukoreshwa muri minisiteri yoroheje, hamwe nijwi ryiza hamwe nubushuhe.
3. Imvange
Ibivangwa ni ibintu bya chimique bitezimbere imikorere ya minisiteri yumye, cyane cyane harimo ibikoresho bigumana amazi, retarders, yihuta, imiti igabanya ubukana, nibindi.
Ibikoresho bigumana amazi: bikoreshwa mugutezimbere amazi ya minisiteri no gukumira amazi guhindagurika vuba, bityo bikongerera igihe cyo kubaka minisiteri, ifite akamaro kanini cyane cyane mubushyuhe bwinshi cyangwa ahantu humye. Ibikoresho bisanzwe bigumana amazi harimo polymers.
Abadindiza: barashobora gutinza igihe cyagenwe cya minisiteri, ikwiranye nubushyuhe bwo hejuru bwubaka kugirango birinde minisiteri gukomera hakiri kare mugihe cyo kubaka.
Kwihuta: kwihutisha inzira yo gukomera ya minisiteri, cyane cyane mubushyuhe buke, akenshi bikoreshwa mukwihutisha reaction ya sima no kunoza imbaraga za minisiteri.
Antifreeze: ikoreshwa mubushyuhe buke kugirango irinde minisiteri gutakaza imbaraga kubera gukonja.
4. Inyongera
Inyongeramusaruro bivuga ibintu bya shimi cyangwa karemano bikoreshwa mugutezimbere ibintu bimwe na bimwe bya minisiteri yumye, mubisanzwe harimo ether ya selile, kubyimbye, gukwirakwiza, nibindi.
Uruhare rwa selile
Cellulose ether nicyiciro cyibintu bya polymer bikozwe muri selile binyuze muburyo bwo guhindura imiti, bikoreshwa cyane mubwubatsi, gutwikira, imiti ya buri munsi nizindi nzego. Kuma-kuvanga minisiteri, uruhare rwa selile ether igaragara cyane mubice bikurikira:
Kunoza uburyo bwo gufata amazi ya minisiteri
Ether ya selile irashobora kongera neza gufata amazi ya minisiteri no kugabanya amazi vuba. Imiterere ya molekuline irimo amatsinda ya hydrophilique, ashobora gukora imbaraga zikomeye zihuza na molekile zamazi, bityo bikagumya gutoboka kandi bikarinda gucika cyangwa ingorane zubwubatsi ziterwa no gutakaza amazi byihuse.
Kunoza imvugo ya minisiteri
Ether ya selile irashobora guhindura amazi no gufatira minisiteri, bigatuma minisiteri iba imwe kandi yoroshye gukora mugihe cyo kubaka. Yongera ubwiza bwa minisiteri ikoresheje umubyimba, ikongera irwanya ivangura, ikabuza minisiteri gutondeka mugihe cyo kuyikoresha, kandi ikemeza ubwubatsi bwa minisiteri.
Kongera imbaraga za minisiteri
Filime yakozwe na selulose ether muri minisiteri ifata neza, ifasha kunoza imbaraga zumubano hagati ya minisiteri na substrate, cyane cyane mubikorwa byo kubaka no gutwikira, birashobora kunoza neza imikorere yubusabane no kwirinda kugwa.
Kunoza guhangana
Gukoresha ether ya selile ifasha kunoza uburyo bwo guhangana na minisiteri, cyane cyane mugihe cyo kumisha, ether ya selile irashobora kugabanya ibice biterwa no kugabanuka hongerwaho ubukana nimbaraga za minisiteri.
Kunoza imikorere yubwubatsi
Cellulose etherIrashobora guhindura neza igihe cyubwubatsi bwa minisiteri, ikongerera igihe cyo gufungura, kandi ikabasha gukomeza imikorere myiza yubwubatsi mubushyuhe bwinshi cyangwa ahantu humye. Byongeye kandi, irashobora kandi kunoza uburinganire nubushobozi bwa minisiteri no kuzamura ubwubatsi.
Nibikoresho byubaka bikora neza kandi bitangiza ibidukikije, gushyira mu gaciro kubigize no kugereranya bigena ireme ryimikorere. Nka nyongera yingirakamaro, ether ya selile irashobora kunoza ibintu byingenzi bya minisiteri yumye, nko gufata amazi, rheologiya, hamwe no gufatira hamwe, kandi bigira uruhare runini mukuzamura imikorere yubwubatsi nubwiza bwa minisiteri. Mugihe inganda zubwubatsi zikomeje kongera ibisabwa mubikorwa byimikorere, ikoreshwa rya selulose ether nibindi byongerera imbaraga mumashanyarazi yumye bizagenda byiyongera, bitanga umwanya munini mubikorwa byiterambere ryinganda.
