Ihinduka rya Ethers ya Cellulose

Ihungabana rya selile ya selile bivuga ubushobozi bwabo bwo kubungabunga imiterere yimiti niyumubiri mugihe, mubihe bitandukanye bidukikije hamwe nibipimo byo gutunganya.Hano hari ibintu bimwe na bimwe bigira ingaruka kumyitwarire ya selile:

1. Hydrolytic Stabilite: Ethers ya selile irashobora kwibasirwa na hydrolysis, cyane cyane mubihe bya acide cyangwa alkaline.Ihungabana rya selile ya selile biterwa nurwego rwabo rwo gusimbuza (DS) n'imiterere yimiti.Hejuru ya DS selulose ethers irwanya hydrolysis ugereranije na DS yo hasi.Byongeye kandi, kuba hari amatsinda arinda nka methyl, Ethyl, cyangwa hydroxypropyl matsinda arashobora kongera hydrolytike ituje ya selile ya ethers.
2. Ubushyuhe bukabije: Ethers ya selile yerekana ituze ryiza ryumuriro mugihe gisanzwe cyo gutunganya no kubika.Nyamara, kumara igihe kinini mubushyuhe bwo hejuru bishobora gutera kwangirika, bikavamo impinduka zijimye, uburemere bwa molekile, nibindi bintu bifatika.Ubushyuhe bwumuriro wa selile ya selile biterwa nibintu nkimiterere ya polymer, uburemere bwa molekile, hamwe no kuba ibintu bihindura ibintu.
3. pH Ihungabana: Ethers ya selile ihagaze neza kumurongo mugari wa pH, mubisanzwe hagati ya pH 3 na 11. Ariko, imiterere ya pH ikabije irashobora kugira ingaruka kumikorere no mumikorere.Imiterere ya acide cyangwa alkaline irashobora gutera hydrolysis cyangwa kwangirika kwa ethers ya selile, bikaviramo gutakaza ububobere no kubyimba.Imiterere irimo selile ya selile igomba gutegurwa kurwego rwa pH murwego rwo guhagarara kwa polymer.
4. Oxidative Stabilite: Ethers ya selile irashobora kwanduzwa na okiside iyo ihuye na ogisijeni cyangwa okiside.Ibi birashobora kubaho mugihe cyo gutunganya, kubika, cyangwa guhura numwuka.Antioxydants cyangwa stabilisateur irashobora kongerwaho mumikorere ya selile ether kugirango iteze imbere okiside kandi irinde kwangirika.
5. Umucyo uhagaze: Ethers ya selile irashobora guhagarara neza kumurika, ariko kumara igihe kinini kumirasire ya ultraviolet (UV) bishobora gutera kwangirika no guhinduka ibara.Stabilisateur yumucyo cyangwa imashini ya UV irashobora kwinjizwa mubikorwa birimo selile ya selile kugirango igabanye fotodegradasiyo kandi igumane ibicuruzwa neza.
6. Guhuza nibindi bikoresho: Ihungabana rya ethers ya selile irashobora guterwa no gukorana nibindi bikoresho muburyo bwo gukora, nk'umuti, ibishishwa, imyunyu, ninyongeramusaruro.Igeragezwa ryubwuzuzanye rigomba gukorwa kugirango ethers ya selile ikomeze itajegajega kandi ntigire icyiciro cyo gutandukana, imvura, cyangwa izindi ngaruka zitifuzwa mugihe uhujwe nibindi bice.

kwemeza ituze rya selile isaba guhitamo neza ibikoresho fatizo, guhitamo neza, uburyo bwiza bwo gutunganya, hamwe nuburyo bukwiye bwo kubika no gufata neza.Ababikora akenshi bakora igerageza rihamye kugirango basuzume imikorere nubuzima bwa selulose ether irimo ibicuruzwa mubihe bitandukanye.
