Kwiyubaka-kwipima birashobora kwishingikiriza kuburemere bwabyo kugirango bibe umusingi uringaniye, woroshye kandi ukomeye kuri substrate yo gushyira cyangwa guhuza ibindi bikoresho, kandi icyarimwe birashobora gukora ubwubatsi bunini kandi bunoze.Kubwibyo, amazi menshi ni ikintu cyingenzi cyane cyo kwipimisha.Byongeye kandi, igomba kugira amazi amwe n'imbaraga zo guhuza, nta kintu cyo gutandukanya amazi, kandi ikagira ibimenyetso biranga ubushyuhe n'ubushyuhe buke.
Mubisanzwe, kwipimisha minisiteri bisaba gutembera neza, ariko amazi ya paste ya sima mubyukuri ni 10-12cm gusa;selulose ether ninyongera yingenzi ya minisiteri ivanze, nubwo umubare winyongera ari muke cyane, irashobora kunoza imikorere ya Mortar, irashobora kunoza imikorere, imikorere, guhuza ibikorwa hamwe no gufata amazi ya minisiteri.
1: Amazi ya minisiteri
Cellulose ether igira uruhare runini mukubika amazi, guhoraho no kubaka ubwubatsi bwa minisiteri.Cyane cyane nka minisiteri yo kwipimisha, fluidity nimwe mubipimo nyamukuru byo gusuzuma imikorere yo kwipimisha.Hashingiwe ku kwemeza imiterere isanzwe ya minisiteri, amazi ya minisiteri arashobora guhinduka muguhindura ingano ya selile.Ariko, niba ibipimo biri hejuru cyane, amazi ya minisiteri azagabanuka, bityo dosiye ya selile ya ether igomba kugenzurwa mugihe gikwiye.
2: Kubika amazi ya Mortar
Kugumana amazi ya minisiteri nigipimo cyingenzi cyo gupima ihame ryimiterere yimbere yimbere ya sima ivanze.Kugirango ukore neza reaction ya hydration yibikoresho bya gel, urugero rwiza rwa selile ya selile irashobora kugumana ubuhehere muri minisiteri igihe kirekire.Muri rusange, igipimo cyo gufata amazi ya slurry cyiyongera hamwe no kwiyongera kwa selile.Ingaruka yo gufata amazi ya selile ya selile irashobora kubuza substrate gufata amazi menshi vuba, kandi bikabuza guhinduka kwamazi, kugirango harebwe niba ibidukikije bitemba bitanga amazi ahagije yo kuvomera sima.Byongeye kandi, ubwiza bwa selulose ether nabwo bugira uruhare runini mu kugumana amazi ya minisiteri.Iyo hejuru cyane, ni byiza gufata amazi.Mubisanzwe, selulose ether ifite viscosity ya 400mpa.s ikoreshwa cyane muri minisiteri yo kwipima, ishobora kunoza imikorere iringaniza ya minisiteri kandi ikongerera ubushobozi bwa minisiteri.
3: Igihe cyo gushiraho Mortar
Cellulose ether igira ingaruka zimwe zo kudindiza kuri minisiteri.Hamwe no kwiyongera kwibigize selulose ether, igihe cyo gushiraho minisiteri kiraramba.Ingaruka mbi ya selulose ether kuri paste ya sima ahanini biterwa nurwego rwo gusimbuza itsinda rya alkyl, kandi ntaho bihuriye nuburemere bwa molekile.Gutoya urwego rwo gusimbuza alkyl, nini ya hydroxyl, niko bigaragara ingaruka zo kudindiza.Kandi uko ibintu biri hejuru ya selile ya ether, niko bigaragara cyane ingaruka zo gutinda kurwego rwa firime yo guhuza hakiri kare ya sima, bityo ingaruka zo kudindiza nazo ziragaragara.
4: Mortar compressive strength nimbaraga zo guhinduka
Mubisanzwe, imbaraga nimwe mubipimo byingenzi byo gusuzuma kugirango bikire ingaruka zo gukiza ibikoresho bya sima bishingiye ku sima.Iyo ibikubiye muri selulose ether byiyongereye, imbaraga zo kwikuramo imbaraga nimbaraga za minisiteri bizagabanuka.
5: Imbaraga zihuza imbaraga
Cellulose ether igira uruhare runini mubikorwa byo guhuza minisiteri.Cellulose ether ikora firime ya polymer ifite ingaruka zifunga hagati ya sima ya hydrata ya sima muri sisitemu yicyiciro cyamazi, iteza amazi menshi muri firime ya polymer hanze ya sima, bikaba bifasha hydratiya yuzuye ya sima, bityo bikazamura umubano. imbaraga za paste nyuma yo gukomera.Muri icyo gihe, ingano ikwiye ya selulose ether yongerera plastike nubworoherane bwa minisiteri, igabanya ubukana bwakarere kinzibacyuho hagati ya minisiteri na substrate, kandi bigabanya ubushobozi bwo kunyerera hagati yimbere.Ku rugero runaka, ingaruka zo guhuza hagati ya minisiteri na substrate zongerewe.Mubyongeyeho, bitewe na selile ya ether muri paste ya sima, agace kihariye kinzibacyuho ninzibacyuho byakozwe hagati yimibumbe ya minisiteri nibicuruzwa bitanga amazi.Isohora ryimiterere ituma intera yinzibacyuho ihinduka cyane kandi idakomeye, kuburyo, kugirango minisiteri ifite imbaraga zikomeye
