Nkibyingenzi byingenzi mukubaka ibicuruzwa bya minisiteri yumye, selulose ether igira uruhare runini mumikorere nigiciro cya minisiteri yumye.Hariho ubwoko bubiri bwa ethers ya selile: imwe ni ionic, nka sodium carboxymethyl selulose (CMC), naho ubundi ntabwo ari ionic, nka methyl selulose (MC), hydroxyethyl selulose (HEC), Hydroxypropyl selulose (HPMC), nibindi Kugeza ubu, ibyinshi mubicuruzwa bya selile ya ether bikoreshwa mubikoresho byubwubatsi.Hamwe niterambere ryihuse ryinganda zivanze na minisiteri yumye, ether ya selile yigihugu cyanjye yageze mubusanzwe, kandi ibintu byibicuruzwa byamahanga bigenzura isoko byaracitse.Hamwe no kwamamara kwinshi mu gukoresha ibicuruzwa bivangwa na minisiteri yumye, igihugu cyanjye kizaba igihugu kinini ku isi gikora amavuta avanze yumye, ikoreshwa rya selile ya selile izarushaho kwiyongera, kandi abayikora nubwoko bwibicuruzwa nabyo biziyongera.Igicuruzwa cyibikorwa bya selulose ether muma yumye-ivanze ya minisiteri yabaye intumbero yibikorwa byabayikora nabayikoresha.
Umutungo wingenzi wa selulose ether ni ukubika amazi mubikoresho byubaka.Hatabayeho kongeramo ether ya selile, urwego ruto rwa minisiteri nshya rwuma vuba kuburyo sima idashobora kuhira muburyo busanzwe kandi minisiteri ntishobora gukomera no kugera kubufatanye bwiza.Muri icyo gihe, kongeramo selile ether ituma minisiteri igira plastike nziza kandi ihindagurika, kandi igahindura imbaraga zihuza za minisiteri.Reka tuvuge ku ngaruka zogushira mubikorwa byumye-bivanze na minisiteri y'ibicuruzwa bya selile ya ether.
1. Ubwiza bwa selile
Ubwiza bwa selile ether bugira ingaruka kubishobora.Kurugero, hasi yuburanga bwa selile ya ether, niko yihuta gushonga mumazi no kunoza imikorere yo gufata amazi.Kubwibyo, ubwiza bwa selulose ether bugomba gushyirwamo nkimwe mumikorere yiperereza ryayo.Muri rusange, ibisigazwa bya sikeri ya selile ya ether nziza ya 0.212mm ntigomba kurenza 8.0%.
2. Kuma igipimo cyo kugabanya ibiro
Igipimo cyo kugabanya ibiro byumye bivuga ijanisha ryubwinshi bwibintu byatakaye mubwinshi bwicyitegererezo cyambere iyo selile ya selile yumye ku bushyuhe runaka.Kubwiza runaka bwa selile ya selulose, igipimo cyo kugabanya ibiro cyumye ni kinini cyane, bizagabanya ibikubiye mubintu bikora muri selile ya selile, bigira ingaruka kumikorere yibikorwa byo hasi, kandi byongera ikiguzi cyubuguzi.Mubisanzwe, gutakaza ibiro kumisha selile ether ntabwo birenze 6.0%.
3. Sufate ivu irimo selile ya ether
Kubwiza runaka bwa selile ya selile, ibivu byivu ni byinshi cyane, bizagabanya ibikubiye mubintu bikora muri selile ya selile kandi bigira ingaruka kumikorere yibikorwa byo hasi.Amazi ya sulfate arimo selile ya ether ni igipimo cyingenzi cyimikorere yacyo.Ufatanije nu musaruro uriho ubu mu gihugu cyanjye gisanzwe gikora selile ya selile, mubisanzwe ivu rya MC, HPMC, HEMC ntirishobora kurenga 2,5%, kandi ivu rya HEC selulose ether ntirishobora kurenga 10.0%.
4. Viscosity ya selile ether
Kugumana amazi ningaruka zibyibushye bya selile ya selile ahanini biterwa nubwiza na dosiye ya selulose ether ubwayo yongewe kumasima ya sima.
5. Agaciro pH ka selulose ether
Ubukonje bwibicuruzwa bya selulose ether bizagenda bigabanuka buhoro buhoro nyuma yo kubikwa ku bushyuhe bwo hejuru cyangwa mu gihe kirekire, cyane cyane kubicuruzwa byijimye cyane, bityo rero birakenewe kugabanya pH.Mubisanzwe, nibyiza kugenzura pH urwego rwa selile ya ether kugeza 5-9.
6. Ikwirakwizwa ryoroheje rya selile ether
Ihererekanyabubasha rya selile ya ether igira ingaruka itaziguye mubikorwa byayo.Ibintu nyamukuru bigira ingaruka kumyuka yumucyo wa selile ether ni: (1) ubwiza bwibikoresho fatizo;(2) ingaruka za alkalisation;(3) igipimo cyibikorwa;(4) igipimo cyo kwishyura;(5) Ingaruka zo kutabogama.Ukurikije ingaruka zo gukoresha, itumanaho ryumucyo wa selile ether ntigomba kuba munsi ya 80%.
7. Ubushyuhe bwa gel ya selile ya ether
Ether ya selile ikoreshwa cyane nka viscosifier, plasitike hamwe nogukomeza amazi mubicuruzwa bya sima, bityo ubukonje nubushyuhe bwa gel ningamba zingenzi ziranga ubwiza bwa selile.Ubushyuhe bwa gel bukoreshwa mukumenya ubwoko bwa selile ya selile, ifitanye isano nurwego rwo gusimbuza selile.Byongeye kandi, umunyu n umwanda birashobora no kugira ingaruka kubushyuhe bwa gel.Iyo ubushyuhe bwumuti buzamutse, polymerose ya selile itakaza buhoro buhoro amazi, kandi ubwiza bwumuti buragabanuka.Iyo geli igeze, polymer iba idafite umwuma rwose ikora gel.Kubwibyo, mubicuruzwa bya sima, ubusanzwe ubushyuhe bugenzurwa munsi yubushyuhe bwa mbere bwa gel.Muriyi miterere, ubushyuhe buringaniye, niko ubukonje bwiyongera, hamwe ningaruka zigaragara zo kubyimba no kubika amazi.
