Irangi ryukuri ryibuye hamwe na Cellulose Ether

Ingaruka yubunini bwa selile ya selile, misile igereranije nuburyo bwo guhindura uburyo bwo gufata amazi no kwera ibintu byerekana irangi ryamabuye nyabyo biraganiriweho, hanyuma ether ya selulose hamwe na anti-selile nziza yo kurwanya irangi ryamabuye nyayo irasuzumwa, kandi imikorere yuzuye irangi ryamabuye irasuzumwa gutahura.

Amagambo y'ingenzi:irangi ryamabuye;kurwanya amazi yera;selile ether

0、Ijambo ry'ibanze

Varnish yamabuye nyayo ni sintetike resin emulsion yumusenyi urukuta rwubatswe rwubatswe rukozwe muri granite karemano, amabuye yajanjaguwe hamwe nifu yamabuye nkibintu byose hamwe, eminioni ya sintetike ya resin emulion nkibikoresho fatizo kandi byuzuzwa ninyongera zitandukanye.Ifite imiterere nuburyo bwo gushushanya amabuye karemano.Mu mushinga wo gushariza hanze yinyubako ndende, itoneshwa nabenshi mubafite ubwubatsi.Ariko, muminsi yimvura, kwinjiza amazi no kwera byabaye bibi cyane kurangi ryamabuye.Nubwo hari impamvu nini itera emulsiyo, kongeramo umubare munini wibintu bya hydrophilique nka selulose ether byongera cyane kwinjiza amazi ya firime yukuri yamabara.Muri ubu bushakashatsi, hasesenguwe ku maboko ya selile ya selulose, ingaruka z’umubare wa selile ya selile, uburemere bwa molekile ugereranije nubwoko bwo guhindura ibintu bikurura amazi kandi byera byerekana irangi ryamabuye.

1. Uburyo bwo kwinjiza amazi no kwera irangi ryamabuye

Nyuma yo gusiga irangi ryamabuye nyayo yumye, ikunda kwera iyo ihuye namazi, cyane cyane mugihe cyambere cyo gukama (12h).Mu bihe by'imvura, igifuniko kizoroha kandi cyera nyuma yo kozwa n'imvura igihe kirekire.Impamvu ya mbere nuko emulsiyo ikurura amazi, naho iyakabiri iterwa nibintu bya hydrophilique nka selulose ether.Cellulose ether ifite imirimo yo kubyimba no kubika amazi.Bitewe no kwangirika kwa macromolecules, imigendekere yumuti itandukanye niy'amazi ya Newtonian, ariko yerekana imyitwarire ihinduka hamwe no guhindura imbaraga zogosha, ni ukuvuga ko ifite thixotropy nyinshi.Kunoza imikorere yubwubatsi bwamabara nyayo.Cellulose igizwe na D-glucopyranosyl (anhydroglucose), kandi formulaire ya molekile yoroshye ni (C6H10O5) n.Ether ya selulose ikorwa na selile ya alcool hydroxyl hamwe na alkyl halide cyangwa ikindi kintu cya etherification mugihe cya alkaline.Hydroxyethyl selulose ether imiterere, impuzandengo yumubare wamatsinda ya hydroxyl yasimbujwe na reagents kumurongo wa anhydroglucose kumurongo wa molekile ya selile yitwa urwego rwo gusimburwa, amatsinda ya 2, 3, na 6 hydroxyl yose asimburwa, kandi urwego ntarengwa rwo gusimburwa ni 3 Amatsinda ya hydroxyl yubusa kumurongo wa molekuline ya selile ya ether irashobora gukorana kugirango ihuze hydrogène, kandi irashobora no gukorana namazi kugirango ibe imigozi ya hydrogen.Kwinjiza amazi no kugumana amazi ya selile ya selile bigira ingaruka itaziguye kumazi no kwera irangi ryamabuye.Kwinjiza amazi no gufata neza amazi ya selile ya selile biterwa nurwego rwo gusimbuza selile, insimburangingo hamwe na polymerisation ya selile ubwayo.

2. Igice cyubushakashatsi

2.1 Ibikoresho byo kugerageza nibikoresho

Imashini ya JFS-550 yimikorere myinshi yo gukurura, gukwirakwiza umuvuduko mwinshi no gusya umucanga: Shanghai Saijie ibikoresho bya Shimi, Ltd.;JJ2000B iringaniza rya elegitoronike: Uruganda rwibikoresho bya Changshu Shuangjie;Imashini yipimisha ya CMT-4200: Shenzhen Sansi Experimental Equipment Co., Ltd.

2.2 Inzira yubushakashatsi

2.3 Inzira yubushakashatsi

Ongeramo amazi, defoamer, bactericide, antifreeze, imfashanyo ikora firime, selile, selile pH hamwe na emulioni kubitandukanya ukurikije formula yo gutatana neza, hanyuma ushyiremo umucanga wamabara hanyuma ubyereke neza, hanyuma ukoreshe urugero rukwiye rwibyimbye Uhindure ubwiza , gutatanya neza, no kubona irangi ryamabuye.

Kora ikibaho ukoresheje irangi ryamabuye, hanyuma ukore ikizamini cyo kweza amazi nyuma yo gukira amasaha 12 (kwibiza mumazi kumasaha 4).

2.4 Ikizamini cyimikorere

Nk’uko JG / T 24-2000 “Synthetic Resin Emulsion Sand Wall Paint” ibivuga, ikizamini cyo gukora kirakorwa, hibandwa ku kurwanya amazi yera ya hydroxyethyl selulose ether irangi ryamabuye nyayo, nibindi bipimo bya tekiniki bigomba kuba byujuje ibisabwa.

3. Ibisubizo n'ibiganiro

Ukurikije imikorere iranga hydroxyethyl selulose ether, ingaruka zubunini bwa hydroxyethyl selulose ether, uburemere bwa molekile ugereranije nuburyo bwo guhindura uburyo bwo kwera-amazi yo kurwanya irangi ryamabuye nyayo.

3.1 Ingaruka ya dosiye

Hamwe no kwiyongera kwa hydroxyethyl selulose ether, irwanya amazi yera irangi ryamabuye nyayo igenda yangirika buhoro buhoro.Umubare munini wa selile ya selile, niko umubare wamatsinda ya hydroxyl yubusa, niko amazi azagenda ahuza hydrogène nayo, igipimo cyo kwinjiza amazi ya firime yukuri yamabara aziyongera, kandi kurwanya amazi bizagabanuka.Amazi menshi muri firime yamabara, niko byoroshye kwera hejuru, bityo kurwanya kwera kwamazi bikaba bibi.

3.2 Ingaruka ya misile igereranije

Iyo ingano ya hydroxyethyl selulose ethers hamwe na molekile zitandukanye ugereranije ni imwe.Ninini nini ya molekile igereranije, niko irushaho kuba irwanya amazi yera irangi ryamabuye nyayo, byerekana ko uburemere bwa molekile ugereranije ya hydroxyethyl selulose ether igira ingaruka kumyuka yera yo gusiga irangi ryamabuye.Ni ukubera ko imiyoboro ya chimique> hydrogène ihuza> imbaraga za van der Waals, nini nini ya misile igereranije ya selile ya ether, ni ukuvuga, uko urwego rwa polymerisiyonike rugenda rwiyongera, niko imiti myinshi iva mu guhuza ibice bya glucose, kandi nini nini. imbaraga zikorana na sisitemu yose nyuma yo gukora hydrogène hamwe namazi, niko imbaraga zo kwinjiza amazi nubushobozi bwo gufata amazi, niko birwanya ububi bwo kwera bwamazi y irangi ryamabuye.

3.3 Ingaruka zuburyo bwo guhindura

Ibisubizo by'ibizamini byerekana ko guhindura hydrophobi ya hydrophobique ari byiza kuruta umwimerere, kandi guhindura anionic ni bibi cyane.Non-ionic hydrophobique yahinduwe ya selile ether, mugushushanya amatsinda ya hydrophobique kumurongo wa molekuline ya selile ya ether.Muri icyo gihe, umubyimba w'icyiciro cy'amazi ugerwaho binyuze mu guhuza hydrogène guhuza amazi no guhuza urunigi.Imikorere ya hydrophobique ya sisitemu iragabanuka, kuburyo hydrophobique imikorere y irangi ryamabuye nyayo iratera imbere, kandi kurwanya amazi yera bikanozwa.Ether yahinduwe na selulose ether ihindurwa na selile na polyhydroxysilicate, itezimbere imikorere yibyibushye, imikorere ya anti-sag hamwe na anti-splash ya selile ya ether, ariko ionicity yayo irakomeye, kandi ubushobozi bwo kwinjiza amazi no kubika neza, irangi ryamabuye nyaryo riba ribi.

4. Umwanzuro

Kwinjiza amazi no kwera irangi ryamabuye nyabyo bigira ingaruka kubintu byinshi nkubunini bwa selile ya selile nuburyo bwo guhindura imitekerereze ya molekile.Kwinjiza amazi no kwera irangi ryamabuye.
