Ifu ya VAE Ifu ya polymer ya RDP (Redispersible) ni inyongeramusaruro zikoreshwa cyane mu nganda z'ubwubatsi. Yongerwa ku bicuruzwa bishingiye kuri sima nka kole z'amatafari, imvange zigenga hamwe na sisitemu zo gukingira inkuta zo hanze kugira ngo inoze imiterere nko gukora neza, gufatana no koroha. Ingano y'uduce, ubucucike bw'ibice n'ubucucike bw'ifu ya polymer ya RD ni ibipimo by'ingenzi bigira ingaruka ku mikorere yazo muri izi koreshwa. Iyi nkuru izibanda ku buryo bwo gupima ubucucike bw'ifu ya polymer ya VAE ifu ya polymer ya RD.
Ubushyuhe busobanurwa nk'igipimo cy'ubudahangarwa bw'amazi mu gutemba. Ku ifu ya VAE RD polymer powders, ubushyuhe ni ikintu cy'ingenzi gikora ku bushyuhe n'ubushobozi bw'imvange ya sima. Uko ubushyuhe bwinshi, ni ko bigora ifu kuvanga n'amazi, bigatuma habaho uduce duto no gukwirakwira ku buryo budahagije. Kubwibyo, ni ngombwa cyane kugumana ubushyuhe bw'ifu ya RD polymer kugira ngo haboneke ireme rihoraho ry'umusaruro wa nyuma.
Uburyo bwo gupima ubukana bw'ifu ya polymer ya VAE powder RD bukorwa hakoreshejwe viscometer izunguruka. Viscometer izunguruka ipima ubukana bw'ingufu ikenewe kugira ngo izunguruke mu gice cy'ifu ya polymer ihagaze mu mazi. Ingufu izunguruka ku muvuduko runaka hanyuma ubukana bupimwe muri centipoise (cP). Ubukana bw'ifu ya polymer burabarwa hashingiwe ku bukana bw'ingufu ikenewe kugira ngo izunguruke.
Intambwe zikurikira zigaragaza uburyo bwo gupima ubukana bw'ifu ya VAE Powder RD Polymer.
1. Gutegura icyitegererezo: Fata icyitegererezo cy'ifu ya RD polymer hanyuma upime kugeza kuri garama 0.1 iri hafi. Shyira icyitegererezo mu gikoresho gisukuye, cyumye kandi cyarangiritse. Andika uburemere bw'igikoresho n'icyitegererezo.
2. Shyira ifu ya polimeri mu mazi: Shyira ifu ya polimeri mu mazi ukurikije amabwiriza y'uwakoze. Ubusanzwe, ifu ya polimeri ivangwa n'amazi hakoreshejwe icyuma gishyushya cyane. Vanga ifu ya polimeri n'amazi byibuze iminota 5 cyangwa kugeza habonetse uruvange rungana. Umuvuduko n'igihe cyo kuvanga bigomba kuba bihuye mu gihe cyose cy'igerageza.
3. Gupima ubukana: koresha viscometer izenguruka kugira ngo upime ubukana bw'ifu ya polimeri. Ingano n'umuvuduko bya spindle bigomba gutoranywa hakurikijwe ubukana bw'ifu ya polimeri. Urugero, niba ubukana bw'ubukana butegerejwe, koresha ingano ntoya ya spindle na RPM iri hejuru. Niba ubukana bw'ubukana butegerejwe, koresha ingano nini ya spindle n'umuvuduko muto.
4. Gupima: Mbere yo gupima, pima viscometer ukurikije amabwiriza y'uwakoze. Ibi birimo gushyiraho amanota ya zeru no kuyipima ukoresheje ibisubizo bisanzwe by'ubukana buzwi.
5. Pima torque: Shyira rotor mu cyuma gifunga ifu ya polymer kugeza igihe iguye burundu. Ipine ntigomba gukora hasi mu gikoresho. Tangira kuzunguza ipine hanyuma utegereze ko ipine ihagaze neza. Andika ipine ipima torque muri centipoise (cP).
6. Gusubiramo: Nibura ibipimo bitatu byiyongera kuri buri gipimo kandi impuzandengo y'ubushyuhe ibarwa.
7. Gusukura: Nyuma yo gupima, sukura neza icyuma gipima n'agakoresho ukoresheje amazi n'isabune. Sukura n'amazi yaciwe hanyuma wumishe witonze.
Ubushyuhe bw'ifu ya RD polymer buterwa n'ibintu byinshi birimo ubushyuhe, pH n'ubwinshi bw'ibipimo. Kubwibyo, ni ngombwa cyane gupima ubushyuhe mu buryo busanzwe. Nanone, hagomba gupimwa ubushyuhe buri gihe kugira ngo hamenyekane imikorere ihoraho y'ifu ya RD polymer.
Muri make, uburyo bwo gupima ubukana bw'ifu ya VAE RD polymer ni ikizamini cy'ingenzi kugira ngo hamenyekane uburyo ibintu bikomoka kuri sima bigenda neza kandi bikore neza. Ikizamini kigomba gukorwa hakoreshejwe ibikoresho n'uburyo busanzwe kugira ngo haboneke ibisubizo nyabyo kandi bishobora kongera gukoreshwa. Ibipimo by'ubukana bigomba gufatwa buri gihe kugira ngo harebwe ubuziranenge bw'ifu ya RD polymer.
