Uburyo bwo kwishyuza bwa selile ether muburyo butandukanye

Ubutugo bwa Cellulose nicyiciro cyibikoresho bya polyment byamazi byabonetse kubishushanyo mbonera bya selile karemano. Common cellulose ethers include methyl cellulose (MC), hydroxyethyl cellulose (HEC), hydroxypropyl methyl cellulose (HPMC), etc. They are widely used in construction, food, medicine, cosmetics and other fields. Uburyo nyamukuru nkuwijimye burimo imitungo yumubiri na shimi yimikoranire hagati yimiterere ya molecular.

1. Imiterere ya molekile ya selile
Uburenganzira bwa Cellulose bwakozwe mu kumenyekanisha abasimbuye zitandukanye (nka Methyl, Ethyl, HydroxyPropyl, n'ibindi) kuri chanine isanzwe ya selile. Iyi nzira igumana imiterere yumurongo wa selile ariko ihindura igisubizo cyoroshye nigisubizo. Kumenyekanisha abasimbuye bituma aba elefli batungutse mu mazi kandi barashobora gukora sisitemu ihamye ya Colloidal mu gisubizo, aricyo gikenewe ku mikorere yacyo.

2. Imyitwarire ya molekile mubisubizo
Ingaruka zijimye za selile ether mumazi ahanini ituruka kumurongo muremure wa virusire washyizweho na molekile zayo mubisubizo. Uburyo bwihariye burimo:

2.1 kubyimba no kurambura iminyururu ya molekile
Iyo ether ether ishonga mumazi, iminyururu ya macromolecular izabyimba kubera hydtion. Iyi minyururu ya molecular yabyimbye kandi ifite amajwi manini, yongera cyane viscosiya. Uku kurambura no kubyimba biterwa n'urwego no gusimbuza urwego rwa selile ya selile, kimwe n'ubushyuhe na PH agaciro k'igisubizo.

2.2 Ububiko bwa Hydrogène hamwe nibikorwa bya Hydrophobic
Ubugari bwa Celecular Iminyururu ikubiyemo umubare munini w'amatsinda ya hydroxyl hamwe nandi matsinda ya hydrophilic, hashobora gukora imikoranire ikomeye na molekile z'amazi binyuze muri hydrogen. Byongeye kandi, abasimbuye ba selile bahuye nurwego runaka rwa hydrophobicirity, kandi aya matsinda ya hydrophobicique, kandi aya matsinda ya hydrerobic arashobora gukora hydrophobic ateranya mumazi, bityo bigamura viscosiya. Ingaruka ihuriweho na hydrogen hamwe nimikoranire ya hydrophobike yemerera selile ether igisubizo cyo gukora leta ihamye-ihamye.

2.3 Kwizirika hamwe no guhura kumubiri hagati yiminyururu ya molecular
Iminyururu ya selile ya ether izakora amafaranga yumubiri mubisubizo kubera ubushyuhe hamwe nimbaraga ziterabwoba, kandi izizo ziyongera uburyo bwo gukemura. Byongeye kandi, mugihe cyibanze, firigo ya selile irashobora gukora imiterere isa numubiri wambukiranya umubiri, bikarushaho kuzamura ubukwe bwigisubizo.

3. Uburyo bukabije bwo gusaba

3.1 Ibikoresho byo kubaka
Mu bikoresho byo kubaka, abatanga na selile bakunze gukoreshwa nkabaribora muri minisiteri no kurera. Barashobora kongera imikorere yubwubatsi n'amazi yo kugumana minisiteri, bityo bigatuma ibyo byorohe byubaka ninyuzi zanyuma. Ingaruka zikabije za elegiri za selile muriyi porogaramu zinyuze ahanini binyuze mu gushiraho ibisubizo-byinshi, kongeramo ibikoresho no kurwanya ibikoresho byacitse.

3.2 Inganda zibiri
Mu nganda zibiryo, abatanga seliki nka HydroxyPropyl MethylcellAlose (HPMC) na hydroxyEthyl the selile. Ibisubizo Byinshi Byuzuye Mubiryo birashobora kongera uburyohe nuburyohe bwibiryo, mugihe ushikamye sisitemu yo gutatanwa mubiryo kugirango wirinde gutsindwa no kugwa.

3.3 Ubuvuzi no kwisiga
Mu rwego rw'ubuvuzi no kwisiga, abakoresha seliki bakoreshwa nk'abakozi baselli na Trickeners yo gutegura ibicuruzwa nk'ibiyobyabwenge, amavuta na cream. Uburyo bwabwo bushingiye ku myitwarire isenyutse mu mazi hamwe n'imiterere y'urusobe rwo hejuru rwashyizweho, gutanga vicosity n'umutekano bisabwa n'ibicuruzwa.

4. Ingaruka z'ibidukikije ku ngaruka mbi
Ingaruka zijimye za filime zirimo ibintu bitandukanye bidukikije, harimo ubushyuhe, PH agaciro hamwe nimbaraga za ionic zimbaraga. Ibi bintu birashobora guhindura impamyabumenyi yo kubyimba no guhuza intermilecular yumurongo wa selile ether urunigi rwa molecular, bityo bigira ingaruka kuri viscosiya. Kurugero, ubushyuhe bwinshi bugabanya ubuswa bwa selile ether igisubizo, mugihe impinduka zihindura imiterere yumurongo wa molekile, bityo bigira ingaruka kuri vinosiya.

Gusaba ubugari bwa selile ether nkuko ububi buterwa nuburyo budasanzwe bwa molecular hamwe nurwego rwo hejuru rwurusobe rwinshi rwakozwe mumazi. Mugusobanukirwa uburyo bwabwo bukabije muri porogaramu zitandukanye, hakoreshwa ingaruka zisanzwe mumirima itandukanye yinganda irashobora kuba nziza. Mugihe kizaza, hamwe ninyigisho yimbitse yumubano uri hagati yimibare ya selile nimikorere, biteganijwe ko Ether Ether ibicuruzwa hamwe nibikorwa byiza bizatera imbere kugirango usohoze ibikenewe mumirima itandukanye.
