Kwiyoroshya-minisiteri irashobora kwishingikiriza kuburemere bwayo kugirango ibe umusingi uringaniye, woroshye kandi ukomeye kuri substrate yo gushyira cyangwa guhuza ibindi bikoresho. Mugihe kimwe, irashobora gukora ubwubatsi bunini kandi bunoze. Kubwibyo, amazi menshi ni ikintu cyingenzi cyane cyo kwishyiriraho ibipimo byiyongereyeho, bigomba kuba bifite amazi amwe n'imbaraga zo guhuza, nta kintu cyo gutandukanya amazi, kandi gifite ibimenyetso biranga ubushyuhe n'ubushyuhe buke.
Mubisanzwe, kwipimisha minisiteri bisaba gutembera neza. Cellulose ether ninyongera nyamukuru ya minisiteri ivanze. Nubwo amafaranga yiyongereye ari make cyane, arashobora kunoza cyane imikorere ya minisiteri. Irashobora kunoza guhuza, gukora no guhuza minisiteri. imikorere no gufata amazi. Ifite uruhare runini mubijyanye na minisiteri ivanze.
1 amazi
Cellulose ether igira uruhare runini mukubika amazi, guhoraho no kubaka ubwubatsi bwa minisiteri. Cyane cyane nka minisiteri yo kwipimisha, fluidite nimwe mubipimo nyamukuru byo gusuzuma imikorere yo kwipimisha. Hashingiwe ku kwemeza ibisanzwe bisanzwe bya minisiteri, amazi ya minisiteri arashobora guhinduka muguhindura ingano ya selile. Ariko, niba dosiye ari ndende cyane, amazi ya minisiteri azagabanuka, bityo dosiye ya selile ya ether igomba kugenzurwa mugihe gikwiye.
Kubika amazi
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 yubukonje, niko gufata amazi neza. 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.
Igihe cyo kwambara
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 igoye kumazi ya sima hakiri kare, bityo ingaruka zo kudindiza nazo ziragaragara.
4 Imbaraga zoroshye nimbaraga zo kwikuramo
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.
Imbaraga 5
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 ka inzibacyuho yimbere 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
