Mortar ni uruvange rwa sima, umucanga namazi bikoreshwa mubikorwa byubwubatsi mubikorwa bitandukanye nka masonry, guhomesha no gutunganya amabati.Ubwiza bwa minisiteri ni ingenzi cyane kuramba n'imbaraga zinyubako.Umwuka uri muri minisiteri ugira uruhare runini mu mikorere ya minisiteri.Kubaho kwimyuka ihumeka muri minisiteri itezimbere imikorere yayo, kugabanya kugabanuka no guturika, kandi byongera imiterere yubushyuhe bwumuriro.Ethers ya selile, nka hydroxypropylmethylcellulose (HPMC) na methylhydroxyethylcellulose (MHEC), ikoreshwa cyane mubikorwa byubwubatsi nk'inyongeramusaruro mu kuzamura ireme n'imikorere ya minisiteri.Iyi ngingo ivuga ku ngaruka za selile ya selile ku kirere cya minisiteri.
Ingaruka ya selile ya ether ku kirere cya minisiteri:
Umwuka uri muri minisiteri biterwa nibintu bitandukanye nkikigereranyo cyamazi-sima, igipimo cyumusenyi-sima, kuvanga igihe, nuburyo bwo kuvanga.Kwiyongera kwa ether ya selile kuri minisiteri birashobora kugira ingaruka zikomeye kubirimo byumwuka.HPMC na MHEC ni hydrophilique polymers ishobora gukuramo amazi no gutatana neza muruvange rwa minisiteri.Bakora nk'igabanya amazi kandi batezimbere imikorere ya minisiteri.Kwongeramo ethers ya selile kumvange ya minisiteri bigabanya amazi akenewe kugirango ugere kumurongo wifuzwa, bityo bigabanye umwuka wa minisiteri.
Nyamara, ingaruka za selile ya selile kumiterere yumuyaga wa minisiteri ntabwo buri gihe ari mbi.Ibi biterwa na dosiye nubwoko bwa selile ether yakoreshejwe.Iyo ikoreshejwe muburyo bukwiye, ethers ya selile irashobora kongera ikirere cya minisiteri mukwongera ituze no kugabanya amacakubiri.Cellulose ether ikora nka stabilisateur, ishobora gukumira neza kugwa kwimyenge mugihe cyo gushiraho no gukomera kwa minisiteri.Ibi byongera imbaraga nimbaraga za minisiteri.
Ikindi kintu kigira ingaruka kumyuka ya minisiteri nuburyo bukwiye bwo kuvanga.Kuvanga byumye bya selile ya selile irimo minisiteri ntabwo byemewe kuko bizatera agglomeration ya selile ya ether selile no gukora ibibyimba muri minisiteri.Kuvanga ibishanga birasabwa kuko byemeza ko habaho itandukanyirizo rya selulose ether mu mvange ya minisiteri kandi ikanoza imikorere yayo.
Inyungu zo gukoresha selile ether muri minisiteri:
Ether ya selile nka HPMC na MHEC itanga ibyiza byinshi iyo ikoreshejwe muri minisiteri.Batezimbere imikorere no gufatira minisiteri, kugabanya igipimo cyamazi-sima no kongera ubudahangarwa bwa minisiteri.Zongera uburebure, imbaraga hamwe na elastique ya minisiteri.Ethers ya selile ikora nkibibyimbye na stabilisateur kandi ikarinda kugwa kwimyuka yumuyaga mugihe cyo gushiraho no gukomera kwa minisiteri.Ibi byongera ubukonje-gukonjesha, kugabanya kugabanuka no kunoza guhangana.Cellulose ether nayo ifite uburyo bwiza bwo gufata amazi, bityo igateza imbere gukira no kuvomera minisiteri.
Mu ncamake, HPMC, MHEC hamwe na ether ya selile ikoreshwa cyane nk'inyongeramusaruro mu nganda zubaka kugirango zongere ubwiza n'imikorere ya minisiteri.Umwuka uri muri minisiteri ni ikintu cyingenzi kigira ingaruka ku mikorere yacyo, kandi kongeramo ether ya selile irashobora kugira ingaruka zikomeye ku kirere cya minisiteri.Nyamara, ingaruka za selile ya selile kumiterere yumuyaga wa minisiteri ntabwo buri gihe ari mbi.Ether ya selile irashobora kongera ikirere cya minisiteri no kunoza imikorere iyo ikoreshejwe muburyo bukwiye hamwe nuburyo bwiza bwo kuvanga.Inyungu zo gukoresha ethers ya selile muri minisiteri zirimo kunoza imikorere, gufatana, guhoraho, kuramba, imbaraga hamwe na elastique ya minisiteri, kimwe no kugabanuka no kunanirwa kurwanya.
