Imiterere yumubiri ya redispersible latex ifu

Redispersible polymer powder (RDP) nifu ya polymer nziza cyane ikoreshwa mubwubatsi, gutwikira no mu zindi nganda. Ikozwe mukwirakwiza polymer emulion mumazi, hanyuma ikuma kugirango ikore ifu. Ifu irashobora guhindurwa byoroshye mumazi kugirango ikore emulisiyo ihamye, ikore polymer itandukanye.

Ibiranga umubiri biranga RDP bigira uruhare runini mubikorwa byayo kandi bikwiranye na porogaramu zitandukanye. Muri iki kiganiro, tuzaganira kumiterere itandukanye ya RDP n'impamvu bifite akamaro.

Ingano nini nogukwirakwiza

Ingano yingingo nogukwirakwiza RDP igena ubworoherane bwayo nuburyo bworoshye bwo gukora. Ingano ntoya, niko bigenda neza. Ifu ya RDP mubisanzwe iri muri micron ya 5-200 kandi ifite ingano ntoya. Ingano zingana zingana zemeza ko ifu ikwirakwira mumazi kandi igatanga emulisiyo ihamye.

Ubucucike bwinshi

Ubwinshi bwinshi nuburemere bwa RDP kubunini bwikigero. Ubwinshi bwifu ya RDP bugira ingaruka kububiko no gutwara. Ubucucike buke busobanura ubunini bwinshi kuburemere bumwe kandi busaba umwanya uhunitse. Kurundi ruhande, ubwinshi bwubwinshi busobanura ubwinshi kuburemere bumwe kandi busaba umwanya muto wo kubika.

Ubwinshi bwinshi bwa RDP buratandukana kubwoko, urwego hamwe no gukora. Urwego rwayo ni 200-700 kg / m3. Muri rusange, ubwinshi bwubwinshi bwifuzwa kugirango byoroshye gutwara no gutwara.

ibirimo amazi

Ibirimo byamazi nikintu cyingenzi kiranga RDP kuko igira ingaruka kububiko bwayo, gutatanya no gukora firime. Ibirimo byamazi birashobora gutandukana bitewe nuburyo bwo gukora, uburyo bwo kubika no kubikora. Mubisanzwe, ibirimo amazi muri RDP biri hagati ya 1-3%, bigatuma amazi agabanuka kugirango arusheho guhunika ifu.

Imiterere yo gukora firime

RDP isanzwe ikoreshwa nkibifata cyangwa bifata mubwubatsi no gutwikira. Imiterere ya firime, nka adhesion, cohesion, hamwe nubworoherane, nibyingenzi mukumenya ibikwiye mubikorwa bitandukanye.

Imiterere ya firime ya RDP biterwa nubwoko bwa polymer yakoreshejwe, ubwoko bwa emulsifier hamwe na polymer yibanze. RDPs yashizweho kugirango itange ibintu byihariye biranga firime kugirango ihuze ibisabwa na porogaramu zitandukanye.

gusubiramo

Redispersibility bivuga ubushobozi bwa RDP bwo gukora emulisiyo ihamye iyo yongewe kumazi nyuma yo gukama. Iyi mikorere irakomeye mubisabwa byinshi kuko itanga uburyo bworoshye bwo gukora no kuvanga.

Isubiranamo rya RDP riterwa n'ubwoko n'ubwiza bwa emulisiferi ikoreshwa mugikorwa cyo gukora nuburyo bwo kubika ifu. Ifu ya RDP irashobora kugira ibintu bitandukanye byo kugarura ibintu kuva mumwanya muto.

ububobere

Viscosity ni igipimo cyo kurwanya ibintu bitemba. Ubukonje bwa emulisiyo ya RDP bugira ingaruka kumikoreshereze yabyo nko gukwirakwizwa, kuringaniza no gutose. Ububasha bwo hejuru butanga firime nziza kandi itajegajega, ariko irashobora gutuma porogaramu igorana.

Ubukonje bwa emulisiyo ya RDP biterwa nubunini bwa polymer, ubwoko bwa emulisiferi na formulaire. Irashobora kuva hasi kugeza hejuru, bitewe nibisabwa.

mu gusoza

Mu gusoza, ibiranga umubiri wa RDP bigira uruhare runini mubikorwa no mubikorwa. Ingano yubunini, ubwinshi bwamazi, ibirimo amazi, imiterere ya firime, redispersibility and viscosity nibintu shingiro byumubiri bya RDP. Mugusobanukirwa ibi biranga, ababikora barashobora kudoda RDP kubikorwa byihariye kugirango bahuze ibyo abakiriya bakeneye. RDP ifatwa nkimwe mu mafu menshi ya polymer kandi akora neza, bigatuma biba byiza mubikorwa byinshi birimo ubwubatsi, ibifuniko hamwe nibifata.
