Ifu ya VAE RDP (Redispersible) ifu ya polymer isanzwe ikoreshwa mubyongeweho mubikorwa byubwubatsi. Yongewe kubicuruzwa bishingiye kuri sima nkibikoresho bifata tile, ibyiyumvo byo kuringaniza hamwe na sisitemu yo gukingira urukuta rwo hanze kugirango tunoze imitungo nko gukora, gufatira hamwe no guhinduka. Ingano yubunini, ubwinshi bwubwinshi nubwiza bwifu ya RD polymer nibintu byingenzi bigira ingaruka kumikorere yabyo. Iyi ngingo izibanda ku buryo bwo gupima ibishishwa bya VAE ifu ya RD polymer.
Viscosity isobanurwa nkigipimo cyo kurwanya amazi. Ifu ya VAE ifu ya RD polymer, viscosity nikintu cyingenzi kigira ingaruka kumazi no gukora mvange ya sima. Iyo hejuru ya viscosity, niko bigoye cyane ko ifu ivangwa namazi, bikavamo ibibyimba no gutatana kutuzuye. Niyo mpamvu, ni ngombwa cyane gukomeza urwego rwijimye rwifu ya RD polymer kugirango ugere kumiterere ihamye yibicuruzwa byanyuma.
Uburyo bwo gupima ibishishwa bya VAE ifu ya RD polymer ifu ikorwa hifashishijwe viscometer. Visometero izenguruka ipima urumuri rusabwa kugirango ruzunguruke mu cyitegererezo cy'ifu ya polymer ihagarikwa mu mazi. Spindle izunguruka ku muvuduko wihariye kandi torque ipimwa muri centipoise (cP). Ubukonje bwifu ya polymer noneho burabarwa hashingiwe kumatara asabwa kugirango azunguruke.
Intambwe zikurikira zerekana uburyo bwuburyo bwikizamini cya Viscosity kuri VAE Ifu ya RD Polymer Powder.
1. Gutegura icyitegererezo: Fata icyitegererezo cyerekana ifu ya RD polymer hanyuma upime hafi 0.1 g. Hindura icyitegererezo mubintu bisukuye, byumye kandi byanduye. Andika uburemere bwa kontineri na sample.
2. Gutatanya ifu ya polymer: Kata ifu ya polymer mumazi ukurikije amabwiriza yabakozwe. Mubisanzwe, ifu ya polymer ivangwa namazi ukoresheje mixer yihuta. Kuvanga ifu ya polymer namazi byibuze iminota 5 cyangwa kugeza habonetse imvange imwe. Kuvanga umuvuduko nigihe bigomba kuba bihoraho mugupimisha.
3. Gupima Viscosity: koresha viscometer izenguruka kugirango upime ubwiza bwihagarikwa rya polymer. Ingano ya spindle n'umuvuduko bigomba gutoranywa ukurikije ibishushanyo mbonera byifu ya polymer. Kurugero, niba biteganijwe ko viscosity yo hasi iteganijwe, koresha ubunini buke bwa spindle na RPM yo hejuru. Niba ibicucu byinshi byitezwe, koresha ubunini bunini bwa spindle n'umuvuduko wo hasi.
4. Calibibasi: Mbere yo gufata ibipimo, koresha viscometer ukurikije amabwiriza yabakozwe. Ibi birimo gushiraho ingingo ya zeru no guhinduranya hamwe nibisubizo bisanzwe byubusa.
5. Gupima itara: Shira rotor mumashanyarazi ya polymer kugeza igihe yarohamye. Spindle ntigomba gukora munsi yikintu. Tangira kuzunguruka hanyuma utegereze gusoma torque kugirango ihagarare. Andika torque isoma muri centipoise (cP).
6. Kwigana: Nibura byibuze bitatu byo kwigana byafashwe kuri buri cyitegererezo hamwe nimpuzandengo ya viscosity yabazwe.
7. Isuku: Nyuma yo gupima birangiye, sukura rotor na kontineri neza ukoresheje amazi na detergent. Kwoza n'amazi yatoboye hanyuma wumuke witonze.
Ubukonje bwifu ya RD polymer yibasiwe nibintu byinshi birimo ubushyuhe, pH hamwe nubushakashatsi. Kubwibyo, ni ngombwa cyane gupima ubukonje mubihe bisanzwe. Na none kandi, ibipimo bisanzwe bya viscosity bigomba gufatwa kugirango harebwe imikorere ya poro ya RD polymer.
Muncamake, uburyo bwo gupima ibishishwa byifu ya VAE ifu ya RD polymer nisuzuma ryingenzi kugirango hamenyekane neza imikorere yimikorere ya sima. Ikizamini kigomba gukorwa hakoreshejwe ibikoresho nuburyo busanzwe kugirango ubone ibisubizo nyabyo kandi byororoka. Ibipimo bya Viscosity bigomba gufatwa buri gihe kugirango hamenyekane ubuziranenge bwifu ya RD polymer.
