Ibintu bigira ingaruka ku kubika amazi kwa ether za selulose

Eteri za selulosi ni ubwoko bw'ingenzi bw'ibikoresho bya polimeri bishongera mu mazi, bikoreshwa cyane mu bwubatsi, ubuvuzi, ibiribwa, imiti ya buri munsi n'izindi nganda. Mu rwego rw'ubwubatsi (nk'uruvange rw'amazi rwumye, kole y'amatafari, ifu ya putty, nibindi), imwe mu miterere y'ingenzi yaeteri za seluloseni ukugumana amazi kwayo, ni ukuvuga ko ishobora kugumana amazi mu buryo bw'ikoranabuhanga mu gihe cyo kuyikoresha kugira ngo wirinde ko amazi ahinduka cyangwa ngo yinjire vuba cyane, bityo bigatuma ibikoresho bikomeza gukora neza. Hari ibintu byinshi bigira ingaruka ku kugumana amazi kwa eteri za cellulose, cyane cyane harimo imiterere yayo ya shimi, urwego rw'isimburwa, ubukana, ingano y'inyongera, ingano y'uduce, igipimo cyo gushonga, n'ibintu bikomoka ku bidukikije.

1. Ibintu bya eteri za selulose ubwazo

Impamyabushobozi yo gusimbuza (DS) n'uburyo bungana

Igipimo cyo gusimbuza bivuze umubare mpuzandengo w'amatsinda ya hydroxyl mu molecule za cellulose zasimbuwe n'amatsinda ya ether. Muri rusange, uko igipimo cyo gusimbuza kiri hejuru, ni ko ether za cellulose zirushaho gukomera kandi ubushobozi bwo kubika amazi burushaho kuba bwiza. Ariko, hari kandi agaciro runaka k'ingenzi. Agaciro gakabije kazatuma habaho gushonga gukabije no gusiga amavuta menshi, bizagira ingaruka ku buryo imiterere y'ibikoresho ihagaze neza.

Uburyo bumwe bwo gusimbuza nabwo ni ingenzi. Uko gusimbuza bingana, ni ko imiterere y'urusobe rw'amazi ikorwa na eteri ya selulose mu mazi irushaho kuba ihamye, kandi ni ko ishobora gufunga ubushuhe neza.

Uburimbane

Ubukana bwa eteri ya selulosi mu mazi bugira ingaruka ku buryo butaziguye ku "bushobozi bwo gufunga" kwayo ku bushuhe. Muri rusange, eteri za selulosi zifite ubukana bwinshi (nka HPMC, HEMC, nibindi) zishobora gukora imiterere y'urusobe rw'amazi rufite ubunini bunini, zikagabanya umuvuduko w'amazi, bityo zigatuma amazi aguma neza. Ariko, ubukana bwinshi cyane buzagira ingaruka ku mikorere y'ibikoresho, nko kwiyongera kw'ingorane mu bwubatsi cyangwa gusiga ibintu mu buryo butaringaniye.

Uburemere bwa molekile n'urwego rwa polymerization

Uko uburemere bwa molekile ya cellulose ether burushaho kuba bwinshi, ni ko ubwinshi bw'ibice by'uruhererekane burushaho gukomera, ni ko umuti wa colloidal urushaho kuba mwiza, kandi ni ko amazi akomeza kugumana. Ariko, hakenewe uburinganire hagati yo kugumana amazi menshi no gushonga byoroshye.

Ingano y'uduce tw'ibice n'uburyo bikwirakwira

Ingano y'uduce twa cellulose ether ifu mbisi igira ingaruka ku muvuduko wayo wo gushonga no gukwirakwira kwayo mu mazi. Uko uduce tuba duto, niko umuvuduko wo gushonga wihuta, kandi niko byoroha gukwirakwira mu bikoresho ku buryo bungana, bityo bikagira uruhare runini mu kubika amazi. Ariko, ifu nto cyane yoroshye kwinjiza ubushuhe no guterana mu gihe cyo kubika no gutwara, bigira ingaruka ku mikorere.

2. Koresha formula n'ibintu bifitanye isano na sisitemu

Amafaranga y'inyongera

Ingano ya eteri ya selulosi yongewe muri iyo formula igira ingaruka zitaziguye ku mikorere yo kubika amazi. Ubusanzwe, uko ingano y’inyongera yiyongera, kubika amazi birarushaho kwiyongera, ariko nyuma yo kurenza urugero runaka, ingaruka z’ubwiyongere zizaba nyinshi, kandi bizagira ingaruka ku kiguzi n’imikorere y’ubwubatsi.

Amazi yo kwinjiza ibindi bikoresho fatizo

Gufata amazi mu bikoresho fatizo nka sima, gypsum, umucanga, nibindi bizagira ingaruka ku kubika amazi. Ibikoresho bifite amazi menshi bizafata amazi vuba mu buryo bwihuse, byihutishe kuma, kandi bitume ingaruka zo kubika amazi mu buryo bw’amazi zirushaho kuba ingenzi. Kubwibyo, muri ubu buryo bw’ikoranabuhanga, hakenewe eteri ya selulose ifite ubukana bwinshi cyangwa ingano yo kongeramo amazi menshi.

Igipimo cy'amazi na sima (W/C)

Mu bikoresho by'ubwubatsi, impinduka mu gipimo cy'amazi na sima zigira ingaruka ku kubika amazi kwa eteri ya selulose. Iyo igipimo cy'amazi na sima kiri hasi, amazi aba make muri sisitemu, kandi igitutu cy'amazi cya eteri ya selulose kikaba kinini; iyo igipimo cy'amazi na sima kiri hejuru, amazi aba ahagije muri sisitemu, kandi eteri ya selulose ishobora gutinza kubura amazi neza.

3. Ibintu bifitanye isano n'ibidukikije

Ubushyuhe

Ubushyuhe bwiyongera bizihutisha umuvuduko w’amazi mu kirere, kandi bigashyira imbere ibisabwa byinshi kugira ngo eteri ya selulose ikomeze kubika amazi. Cyane cyane mu bidukikije bishyushye kandi byumye, iyo eteri ya selulose ikomeje kubika amazi nabi, byoroshye gutuma sima, puti n'ibindi bikoresho by'ubwubatsi bicika, bigatera ifu kandi ntibigire imbaraga nyinshi.

Icyitonderwa ni uko uburyo eteri ya cellulose ishonga mu bushyuhe bwinshi nabwo buzahinduka, kandi ubwoko bumwe na bumwe buzahinduka, bigira ingaruka ku mikorere yayo yo kugenzura ubushuhe.

Ubushuhe n'umuvuduko w'umuyaga

Iyo ubushuhe bw'ikirere buri hasi kandi umuvuduko w'umuyaga uri hejuru, amazi ahinduka mu kirere, kandi sisitemu ishobora gutakaza amazi, ibyo bikaba bisaba igikoresho cyiza cyo kuyabika. Mu hantu hari ubushuhe bwinshi, amazi ntabwo byoroshye kuyatakaza, kandi umuvuduko wo kubika amazi wa eteri ya cellulose uba muto cyane.

4. Ibintu by'ubwubatsi

Ubugari bwo gusiga n'uburyo bwo gukora

Gusiga amazi mu byiciro bito bikunze kugabanya amazi kurusha gutakaza urwego runini, bityo imiterere y’igice gito ishingiye cyane kuri eteri ya selulose ifite amazi menshi. Muri icyo gihe, guhuza amazi, uburyo bwo gusiga (bwa mekanike cyangwa ubw’intoki), umuvuduko wo kwinjiza amazi mu gice cy’amazi, nibindi nabyo bigira ingaruka ku mikorere nyayo y’imikorere yo kubika amazi mu byiciro.

Amazi yo kwinjiza substrate

Urugero, uburyo amazi yinjira mu byuma nk'amatafari, sima, na gypsum biratandukanye, ibyo bizagira ingaruka ku bushobozi bwa eteri ya cellulose bwo kubika amazi. Uko eteri irushaho gukurura amazi, ni ko irushaho gukurura amazi mu cyuma vuba, kandi eteri ya cellulose igomba gukora vuba uruzitiro rufata amazi.

ItsindaImiterere ya eteri ya selulose ibungabunga amazini imiterere iterwa n'ibintu byinshi. Imiterere yayo (nk'urugero rwo gusimbuza, ubushyuhe, ingano y'uduce), ibidukikije ikoreshwa (ubushyuhe, ubushuhe, umuvuduko w'umuyaga) na formula y'ubwubatsi (ingano y'inyongera, igipimo cy'amazi na sima, imiterere y'ibikoresho fatizo) bizagira ingaruka zikomeye ku mikorere yayo. Kubwibyo, mu ikoreshwa, ubwoko n'ingano ya eteri ya selulose bigomba gutoranywa mu buryo bukwiye hakurikijwe ikoreshwa ryihariye n'igishushanyo mbonera cya formula kugira ngo hagerwe ku ngaruka nziza zo kubika amazi no gukora neza mu bwubatsi.
