Kuvuga ubwoko nibiranga abarimbyi

Thickener ni ubwoko bwihariye bwo kongeramo abantu, imikorere yayo ni yo kongera viscosity yamazi arangi, anoza imikorere yububiko, imikorere yubwubatsi ningaruka za firime zo gusiga irangi.

Ibiranga ibibi bitandukanye

1. Inorurnic thicker

Ikoreshwa cyane ni Organic Bentote, hamwe nikintu kinini ni Montontorloniya. Imiterere idasanzwe yakozweho irashobora guha agaciro ifiriti ifite pseudopplastique ikomeye, Tweudropppppppplastity, Twexotropy, guhanuka no gukomera no gukinisha. Ihame ryo kwinuba nuko ifu ikurura amazi ikabyimba kugirango yinube icyiciro cyamazi, niyo mpamvu ifite akabari runaka.

Ibibi ni: Ibikorwa bibi no gushyira hejuru imikorere, ntabwo byoroshye gutatanya no kongeramo.

2. Cekwi

Bikoreshwa cyane ni hydroxyyerthyl selile (HEC), ifite imikorere minini, ihagarikwa, gutatanya no kugumana amazi, cyane cyane kunyeganyega mu mitungo y'amazi.

Ibibi ni: Ingaruka zo kurwanya amazi yo gutwita, imikorere idahagije yo kurwanya ihohoterwa, hamwe n'imikorere myiza.

3. Acrylic

Acrylic Trickeners muri rusange igabanijwemo ubwoko bubiri: acryclc alkali-yuzuye imfubyi (ase) hamwe na alkali-yuzuye ibibyimba bya alkali (hase).

Ihame ribyimbye rya acryc acide alkali-rinini cyane (ase) ni ugutandukana na alkaline, kugirango urunigi rwa electrostatine runyuze hagati yimibonano mpuzabitsina, kunoza visosi yicyiciro gishize. Ubu bwoko bwa Thickener nabwo bufite imikorere miremire, pseudopplastique ikomeye hamwe no guhagarikwa neza.

Umwanya wa alkali-urwenya rwa alkali (hase) itangiza amatsinda ya hydrophobic hashingiwe kubigezweho bisanzwe bya alkali (ase). Mu buryo nk'ubwo, iyo PH ihinduwe muri alkaline, kimwe-gitsina gutangwa hagati ya caxxylate, intungane zituma urunigi rwe ruva mumitwe yerekeranye nimiterere yintebe; Amatsinda ya Hydrophobic yatangijwe ku munyururu nyamukuru arashobora kwiteranya na latex kugirango wongere vino yicyiciro cya Emilsion.

Ibibi ni: Korohewe na PH, imigezi idahagije no kurinda firime irangi, byoroshye kubyimba nyuma.

4. Polyurethane

Polyurethane ufite ubumwe bwa Thickener (Heur) ni hydrophobwa yahinduwe ethoxphoblique yahinduwe polyurethane yamazi-polymer, ari mubindi bitari byo muri wionic Thuckener. Igizwe nibice bitatu: Urufatiro rwa Hydrophobic, Urunigi rwa Hydrophilic na Base Polyurethane. Gishisha Polinethane mu gisubizo gitangaje, kandi urunigi rwa hydrophilic ruhagaze mu cyiciro cy'amazi. Ihuriro rya Hydrophobic ryifatanije ninzego za hydrophobike nkimpapuro za latex, kubaga, hamwe na pigment. , gukora imiterere yimiyoboro itatu, kugirango ugere ku ntego yo kubyimba.

Irangwa no kubyimba kw'icyiciro cya Emulsion, urujya n'uruza rwiza kandi ruringaniye imikorere, ibyiza byijimye kandi bikaze byo kubikamo ibintu bihamye, kandi nta FI ntarengwa; Kandi ifite ibyiza byo kurwanya amazi, gloss, gukorera mu mucyo, nibindi.

Ibibi ni: Muri sisitemu yo hagati na make ya virusi itera induru ku ifu ntabwo ari nziza, kandi ingaruka zijimye zigira ingaruka byoroshye kubitatanye no gukemurwa.
