1. Incamake ya HPMC
Hydroxypropyl methylcellulose (HPMC)ni ether ya cellulose idafite ionic ikunze gukoreshwa nk'ingufu zo kubika amazi no kunoza imikorere muri mortier. Muri mortier systems, ntabwo ihindura gusa rheology n'igihe cyo gukora ahubwo inagira ingaruka ku buryo butaziguye cyangwa butaziguye ku mbaraga za mortier ikomeye. Iyi ngaruka ifitanye isano rya hafi n'ingano ya HPMC, urwego rwo gusimbuza, ubukana, ikoreshwa, n'imiterere y'akazi.
2. Ingaruka nziza za HPMC ku mbaraga za Mortar
2.1. Kunoza imikorere myiza y'amazi ya sima
Imiterere ikomeye ya HPMC yo kubika amazi igabanya gutakaza amazi mu gihe cyo kubaka sima, cyane cyane iyo hari ubushyuhe bwinshi, umuyaga mwinshi, cyangwa ibintu bitonyanga amazi. Ibi bituma ibice bya sima bitongera amazi. Gutongera amazi neza bituma habaho ibintu byinshi bitongera amazi mu sima (nk'ibuye rya CSH) muri sima, bifasha kongera imbaraga zabyo haba mu ntangiriro ndetse no mu nyuma.
2.2. Kugabanya itandukanyirizo n'amaraso
Kutageranya sima n'ibice bya sima mu buryo butaringaniye bishobora gutuma ibice bya sima bitagira imbaraga nyuma yo gukomera. HPMC yongera ubukana bw'imikorere y'ibice, igabanya gutuza kw'ibice bya sima no kwinjira kw'amazi, bityo bikanoza imiterere y'ibice bya sima no kongera imbaraga z'imiterere muri rusange.
2.3. Kunoza uburyo bwo guhuza hagati y'urusobe rw'amabara
Mu gihe cyo gutonyanga amazi, HPMC ikora firime ya polimeri ikwirakwizwa neza, ikorana n'ibicuruzwa byo gutonyanga sima kugira ngo yongere uburyo ikoranabuhanga n'imiti bifatanye hagati ya sima n'ubutaka. Ibi ntibinongera imbaraga zo gufatanya gusa ahubwo binanongera imbaraga zo gukanda muri rusange.
2.4. Kugabanya ibyago byo kwangirika kw'imitsi
Mu kubika amazi no kurekura buhoro buhoro ubushyuhe bw'amazi, HPMC ishobora kugabanya gucikagurika vuba mu gishishwa, bigatuma habaho gukwirakwira kw'imihangayiko hamwe no kwirinda ubwinshi bw'imihangayiko mu gace runaka bushobora gutuma imbaraga zigabanuka.
3. Ingaruka mbi zishobora guterwa na HPMC ku mbaraga za Mortar
3.1. Gukoresha cyane bitera gutakaza imbaraga
HPMC ni polymer y’umwimerere kandi ntabwo igira uruhare mu mikorere y’amazi ya sima. Iyo yongewemo ku bwinshi, ishobora gukora igice kinini cy’umwimerere muri mortier ikomeye, ikagabanya ubucucike bw’ibikoresho bidafite umwimerere kandi bigatera kugabanuka k’imbaraga zo gukanda.
3.2. Igipimo cy'amazi ya sima kidakomeza
Kunywa kwa HPMC bishobora gutwikira ubuso bw'uduce twa sima, bikabangamira ikwirakwira ry'amazi no gutinza uburyo amazi akoreshwa. Iyi ngaruka idindiza iterambere ry'imbaraga hakiri kare. Nubwo ishobora kugarurwa igice nyuma, ntabwo ari byiza ku ikoreshwa risaba imbaraga zihuse (nk'imashini zisana vuba).
3.3. Ingaruka zo kwinjiza umwuka
Hari HPMC zimwe na zimwe zifite ubukana bwinshi zikunze gushyiramo udupira duto mu gihe cyo kuvanga, bikongera umwuka uri muri mortilage. Iyo utu dupira tudasenyutse, dukora imyenge nyuma yo gukomera, bigagabanya imbaraga zo gukanda.
4. Ibintu by'ingenzi bigira ingaruka ku gipimo cy'amazi mu mubiri
4.1. Impamyabushobozi ya HPMC yo gusimbuza no kuba mu buryo bungana
Ingano yo hejuru yo gusimbuza hamwe n'ubushyuhe bwinshi bwa HPMC bigira uruhare runini mu kubika amazi, ariko kandi binatuma amazi adakomeza kugabanuka cyane ndetse bikanagira ingaruka ku guhumeka kw'umwuka.
Ubwoko bw'ibimera bifite ubukana buke bigira ingaruka nke ku buryo amazi atemba neza no gukora neza, kandi ibyago byo kubura imbaraga ni bike.
4.2. Kugenzura Igipimo
Igipimo gisanzwe cya HPMC mu buryo bw'imyobo yumye ni 0.1% kugeza 0.3% by'uburemere bw'ibikoresho bikoreshwa muri sima. Kurenga uru rugero bishobora gutuma imbaraga zigabanuka byoroshye.
4.3. Sisitemu yo Gutegura
Iyo irimo ifu ya polymer ishobora gusubirwamo (RDP), ingaruka nziza za HPMC na RDP zishobora kunoza cyane ubworoherane n'ubufatane, kandi zikagira ingaruka nziza ku mbaraga zo guhindagurika.
Mu buryo bworoheje cyangwa bufite imyenge, kubika amazi kwa HPMC ni ingenzi cyane, bigatuma imbaraga zigabanuka cyane.
4.4. Imiterere y'inyubako n'uburyo bwo kuyitunganya
Ingaruka nziza za HPMC ku mbaraga zigaragara cyane mu bushyuhe bwinshi, ubushuhe buke, cyangwa umuyaga mwinshi. Ku rundi ruhande, mu bidukikije bifite ubushuhe kandi iyo substrate idafata amazi, inyungu yayo yo kubika amazi iba nke, kandi ingano irenze urugero ishobora no kugira ingaruka mbi ku mbaraga.
5. Inama zo kunoza imikorere
5.1. Kugenzura neza igipimo
Mu gihe ugenzura ko ikoreshwa rikora neza, koresha igipimo gito gishoboka kugira ngo wirinde imiterere ikabije ishobora kugabanya imbaraga.
5.2. Koresha hamwe na Defoamers
Kugira ngo ukemure ibibazo byo kwinjira mu mwuka hamwe na HPMC ifite ubukana bwinshi, ongeramo ingano ikwiye ya defoamer kugira ngo ugabanye utubumbe tw'umwuka n'imyenge y'umwuka.
5.3. Gukoresha ibintu bihuza n'ibindi bintu by'inyongera
Iyo ihujwe n'ifu ya polymer ishobora gushonga, lignin sulfonates, n'izindi nyongeramusaruro, ishobora kongera imbaraga no kuramba mu gihe ikomeza gukora neza.
5.4. Guhindura imiterere y'ikoreshwa
Ku bijyanye n'amatafari yo gufunga no gufunga ibintu, shyira imbere imbaraga zo gufatanya no gukora neza, mu gihe imbaraga zo gukanda zishobora kwangirika ku rugero runaka.
Ku bijyanye no gusana mortiers, igipimo cya HPMC kigomba kugabanywa kugira ngo gikomeze gukomera hakiri kare.
HPMC igira ingaruka ebyiri ku mbaraga za morti: igipimo gikwiye n'urwego rukwiye bishobora kongera ubwinshi bw'imiterere n'uburambe bwa mortiweri muri rusange, mu gihe igipimo kirenze urugero cyangwa urugero rudakwiye bishobora kugabanya imbaraga. Guhitamo siyansi no kugenzura igipimo ni ingenzi mu gukoresha ibyiza bya HPMC mu gihe hirindwa ingaruka mbi zayo.
