Kwiyubaka-minisiteri irashobora kwishingikiriza kuburemere bwayo kugirango ibe umusingi uringaniye, woroshye kandi ukomeye kuri substrate yo gushyira cyangwa guhuza ibindi bikoresho.Irashobora kandi gukora ubwubatsi bunoze ahantu hanini.Amazi menshi ni ikintu cyingenzi cyane cyo kwipimisha.;Byongeye kandi, igomba kandi kugira amazi amwe n'imbaraga zo guhuza, ntibitange amacakubiri y'amazi, kandi ikagira ibiranga ubushyuhe n'ubushyuhe buke.
Mubisanzwe, kwipimisha minisiteri bisaba gutembera neza.Cellulose etherni inyongera yingenzi kubiteguye-bivanze na minisiteri.Nubwo umubare winyongera ari muto cyane, urashobora kunoza cyane imikorere ya minisiteri.Irashobora kunoza ubudahwema, imikorere ikora, hamwe na Adhesion hamwe nububiko bwamazi, nibindi. Ifite uruhare runini mubijyanye na minisiteri ivanze.
Amazi
Cellulose etherigira ingaruka zikomeye kubigumana byamazi, guhoraho, no kubaka ubwubatsi bwa minisiteri.By'umwihariko kuri kwipimisha minisiteri, fluidity nimwe mubipimo nyamukuru byo gusuzuma imikorere yo kwipimisha.Hashingiwe ku kwemeza ibisanzwe bisanzwe bya minisiteri, amazi ya minisiteri arashobora guhinduka muguhindura ingano ya selile.Nyamara, hejuru cyane igipimo kizagabanya umuvuduko wa minisiteri, bityo dosiye ya selulose ether igomba kugenzurwa mugihe gikwiye.
Kubika amazi
Kubika amazi ya Mortar ni ikimenyetso cyingenzi cyo gupima ihame ryimiterere yimbere ya sima nshya.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 ya ether.Igikorwa cyo kugumana amazi ya selulose ether kirashobora kubuza substrate gufata amazi menshi vuba kandi bikabuza guhumeka kwamazi, bityo bigatuma ibidukikije bidahungabana bitanga amazi ahagije yo kuvoma sima.Byongeye kandi, ubwiza bwa selulose ether nabwo bugira uruhare runini mu kugumana amazi ya minisiteri.Iyo hejuru yubukonje, niko gufata amazi neza.Ether ya selile ifite ubwiza rusange bwa 400 mpa.s ikoreshwa cyane muri minisiteri yo kwipima, ishobora kunoza imikorere iringaniza ya minisiteri kandi ikazamura ubucucike bwa minisiteri.
Igihe cyo guterana
Cellulose etherifite ingaruka zimwe zo kudindiza kuri minisiteri.Mugihe ibikubiye muri selulose ether byiyongera, igihe cyo gushiraho minisiteri cyiyongera.Ingaruka mbi ya selile ya ether kuri sima ya sima ahanini biterwa nurwego rwo gusimbuza amatsinda ya alkyl kandi ntaho ihuriye nuburemere bwa molekile.Ingano ntoya ya alkyl yo gusimbuza, nini ya hydroxyl, hamwe ningaruka zo kudindiza.Kandi uko ibintu byinshi biri muri selulose ether, niko bigaragara cyane firime ya firime igoye ni mukurinda hydrata ya sima hakiri kare, bityo rero, niko bigaragara ingaruka zo kudindiza.
Imbaraga zihindagurika n'imbaraga zo kwikuramo
Imbaraga nimwe mubipimo byingenzi byo gusuzuma kugirango bigerweho ingaruka zifatika za sima zishingiye kubutaka bwa sima.Mugihe ibiri muri selile ya selile yiyongera, imbaraga zo kwikuramo imbaraga nimbaraga za minisiteri bizagabanuka.Igomba kugenzurwa murwego runaka rwumvikana.
Imbaraga zihuza
Cellulose ether igira uruhare runini kumiterere ya minisiteri.Cellulose ether ikora firime ya polymer ifite ingaruka zo gufunga hagati ya sima ya hydrata ya sima muri sisitemu yicyiciro cyamazi, iteza imbere amazi menshi muri firime ya polymer hanze ya sima, ibyo bikaba bifasha hydrata yuzuye ya sima, bityo bikazamura imbaraga za Bond nyuma yo gukomera.Muri icyo gihe, ingano ikwiye ya selulose ether yongerera plastike nubworoherane bwa minisiteri, igabanya ubukana bwakarere kinzibacyuho hagati ya minisiteri nibikoresho fatizo, kandi bikagabanya ubushobozi bwo kunyerera hagati yimbere.Ku rugero runaka, ingaruka zo guhuza hagati ya minisiteri nibikoresho fatizo zongerewe.Mubyongeyeho, bitewe na selile ya ether muri sima ya sima, hashyizweho akarere kihariye kinzibacyuho nintera yimbere hagati yibice bya minisiteri nibicuruzwa bitanga amazi.Isohora ryimiterere ituma intera yinzibacyuho ihinduka kandi igakomera.Kubwibyo, kugirango minisiteri igire imbaraga zikomeye zo guhuza.
