Nibihe Byiza bya Cellulose Ethers?

Ether ya selile ni itsinda rya polymer zishonga amazi zikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima. Ether ya selulose ihindurwa hakoreshejwe uburyo bwa chimique kugirango itange ibintu byihariye bituma iba ingirakamaro mubikorwa bitandukanye byinganda. Ethers zimwe na zimwe zisanzwe zirimo methyl selulose (MC), hydroxypropyl selulose (HPC), hydroxyethyl selulose (HEC), na hydroxypropyl methyl selulose (HPMC). Imiterere ya ether ya selile yatewe nimiterere yimiti hamwe nurwego rwo gusimbuza. Dore bimwe mubintu rusange bya selulose ethers:

1. Amazi meza:

• Ether ya selulose yerekana amazi meza cyane, bigatuma akoreshwa mumazi ashingiye kumazi. Uyu mutungo utuma byinjizwa byoroshye muri sisitemu zitandukanye zamazi, nk'ibara, amata, hamwe na farumasi.

2. Ubushobozi bwo gukora firime:

• Ethers nyinshi ya selile ifite ubushobozi bwo gukora firime mugihe igisubizo cya polymer cyumye. Uyu mutungo ni ingirakamaro cyane mubisabwa nka coatings, aho hifuzwa gushiraho firime ikingira.

3. Guhindura umubyimba no guhindura imvugo:

• Ethers ya selile ni nziza cyane kandi ihindura imvugo. Barashobora kongera ubwiza bwibisubizo kandi bagatanga igenzura ryimiterere yimyunyu ngugu. Uyu mutungo ufite agaciro mubicuruzwa nkamabara, ibifatika, nibintu byita kumuntu.

4. Gufatanya no guhambira:

• Ether ya selulose igira uruhare mugutezimbere kwifata, kuzamura imiterere yibikoresho. Ibi nibyingenzi mubisabwa nka wallpaper paste, aho guhuza ibice bitandukanye ni ngombwa.

5. Kugabanya Ubushyuhe bwo hejuru:

• Ethers zimwe na zimwe zifite ubushobozi bwo kugabanya ubukana bwubutaka muri sisitemu ishingiye kumazi. Uyu mutungo ni ingirakamaro mubisabwa nka detergent, aho byifuzwa neza no gukwirakwiza.

6. Ubushyuhe bwa Thermal:

• Ethers zimwe na zimwe za selile zerekana imiterere yumuriro. Ibi bivuze ko zishobora gukora gele cyangwa kubyimba mugihe ziterwa nubushyuhe, zitanga ubushyuhe bushingiye kubushyuhe bwo kugenzura.

7. Guhagarara mu gisubizo:

• Ether ya selulose muri rusange yerekana ituze ryiza mugukemura, kubungabunga imitungo yabo mugihe. Uku gushikama ningirakamaro kubikorwa byigihe kirekire byibicuruzwa bikoreshwa.

8. Guhuza nibindi bikoresho:

• Ether ya selile irashobora guhuzwa nibintu byinshi bikoreshwa mubisanzwe, harimo umunyu, surfactants, nizindi polymers. Uku guhuza kwemerera porogaramu zitandukanye mubikorwa bitandukanye.

9. Ibinyabuzima bishobora kubaho:

• Ether ya selile ikomoka kubishobora kuvugururwa kandi bifatwa nkibinyabuzima. Ibi bidukikije nibyingenzi mubikorwa aho biodegradability ari ikintu cyingenzi gisuzumwa.

10. Ntabwo ari uburozi kandi butekanye:

11. pH Guhagarara:

12. Pseudoplastique:

13. Kwihanganira umunyu:

Ni ngombwa kumenya ko imiterere yihariye ya selile ya selile ishobora gutandukana bitewe n'ubwoko bwa selile na selile yo kuyisimbuza. Ababikora batanga ibisobanuro birambuye bya tekiniki kuri buri gicuruzwa cya selulose ether, gifasha abashinzwe guhitamo guhitamo impinduka zikwiye kubikorwa byabo byihariye.
