Redispersible latex powder RDP imikorere nuburyo bwo gupima viscosity

Redispersible polymer powder (RDP) ni kopolymer ya vinyl acetate na Ethylene, ikoreshwa cyane cyane muguhuza ibikoresho byubwubatsi. Itezimbere imbaraga, kuramba no guhuza ibicuruzwa bishingiye kuri sima mugukora firime ihamye mugihe gikomeye. RDP ni ifu yumye ikenera gusubirwamo mumazi mbere yo kuyikoresha. Imiterere nubwiza bwa RDP nibintu byingenzi kuko bigira ingaruka kumiterere yibicuruzwa byanyuma. Iyi ngingo isobanura imikorere ya RDP nuburyo bwo gupima ibishishwa bishobora gufasha ababikora kuzamura ireme ryibicuruzwa no kwemeza kunyurwa kwabakiriya.

Uburyo bwo gupima imikorere ya RDP

Uburyo bwo gupima imikorere ya RDP bwateguwe kugirango busuzume ubushobozi bwa RDP bwo kunoza imikorere yibicuruzwa bishingiye kuri sima. Igikorwa cyo kwipimisha nuburyo bukurikira:

1. Gutegura ibikoresho

Tegura ibikoresho bikurikira: RDP, sima ya Portland, umucanga, amazi, na plastike. Kuvanga sima ya Portland n'umucanga mukigereranyo cya 1: 3 kugirango ubone kuvanga byumye. Tegura igisubizo uvanga amazi na plasitike mukigereranyo cya 1: 1.

2. kuvanga

Kuvanga RDP n'amazi muri blender kugeza habonetse igituba kimwe. Ongeramo ibishishwa byumye hanyuma uvange muminota 2. Ongeramo igisubizo cyamazi ya plastike hanyuma uvange muminota 5 yinyongera. Ibivanze bivamo bigomba kugira umubyimba mwinshi, urimo amavuta.

3. Saba

Ukoresheje umutambiko, ukwirakwiza imvange kubyimbye bya 2mm hejuru yisuku, yumye, iringaniye. Koresha uruziga kugirango woroshye hejuru kandi ukureho umwuka mwinshi. Reka ibyitegererezo bikire ubushyuhe bwicyumba muminsi 28.

4. Gusuzuma imikorere

Ingero zakize zasuzumwe imitungo ikurikira:

- Imbaraga zo guhonyora: Imbaraga zo kwikuramo zapimwe hakoreshejwe imashini igerageza isi yose. Imbaraga zo guhonyora zigomba kuba hejuru kurugero rwo kugenzura nta RDP.
- Imbaraga zoroheje: Imbaraga za flexural zapimwe hakoreshejwe ikizamini cyingingo eshatu. Imbaraga zihindagurika zigomba kuba hejuru kurenza urugero rwo kugenzura nta RDP.
- Imbaraga zifatika: Imbaraga zifatika zapimwe hakoreshejwe ikizamini cyo gukurura. Imbaraga zinguzanyo zigomba kuba hejuru kurenza urugero rwo kugenzura nta RDP.
- Kurwanya amazi: Ingero zakize zinjijwe mumazi amasaha 24 hanyuma imitungo irongera irasuzumwa. Imikorere yayo ntigomba kugira ingaruka zikomeye nyuma yo guhura namazi.

Uburyo bwo gupima imikorere ya RDP burashobora gutanga amakuru afatika kandi yuzuye kubikorwa bya RDP mugutezimbere imikorere yibicuruzwa bishingiye kuri sima. Ababikora barashobora gukoresha ubu buryo kugirango bahindure imikorere ya RDP kandi barebe neza ibicuruzwa byiza.

Uburyo bwo Kwipimisha RDP

Uburyo bwikizamini cya RDP bwateguwe kugirango dusuzume imyitwarire ya RDP mumazi. Igikorwa cyo kwipimisha nuburyo bukurikira:

1. Gutegura ibikoresho

Tegura ibikoresho bikurikira: RDP, amazi ya deionion, viscometer, na fluid ya Calibration. Ikirangantego cyubwinshi bwamazi ya kalibrasi kigomba kuba kimwe nubushake buteganijwe bwa RDP.

2. Gupima ubunini

Gupima ubwiza bwamazi ya kalibrasi hamwe na viscometer hanyuma wandike agaciro. Sukura viscometer hanyuma wuzuze amazi ya deionion. Gupima ubwiza bwamazi hanyuma wandike agaciro. Ongeramo umubare uzwi wa RDP mumazi hanyuma ubyuke buhoro kugeza igihe habonetse imvange imwe. Reka uruvange rwicare iminota 5 kugirango ukureho umwuka mwinshi. Gupima ubwiza bwuruvange ukoresheje viscometer hanyuma wandike agaciro.

3. Kubara

Kubara ubwiza bwa RDP mumazi ukoresheje formula ikurikira:

Ubucucike bwa RDP = (Uruvangitirane ruvanze - Amazi yo mu mazi) /

Uburyo bwo gupima ubukana bwa RDP butanga kwerekana uburyo byoroshye RDP ihinduka mumazi. Kurwego rwo hejuru rwinshi, niko bigora kugarurwa, mugihe hasi yubukonje, byihuse kandi byuzuye byongeye kugarurwa. Ababikora barashobora gukoresha ubu buryo kugirango bahindure imikorere ya RDP kandi barebe neza ko byongera guhinduka.

mu gusoza

Imiterere ya RDP nuburyo bwo kwipimisha ni ibikoresho byingenzi byo gusuzuma ubuziranenge bwa RDP no kunoza imikorere yabyo. Ukoresheje ubu buryo, ababikora barashobora kwemeza ko ibicuruzwa byabo bya RDP byujuje imikorere isabwa kandi byoroshye-gukoresha-gukoresha, bityo bikongerera abakiriya kunyurwa nubudahemuka. Ababikora barasabwa gukurikiza uburyo busanzwe bwo kwipimisha no gukoresha ibikoresho byahinduwe kugirango babone ibisubizo nyabyo kandi byizewe. Mu gihe ikoranabuhanga rya RDP rikomeje gutera imbere, ibyifuzo by’ibikorwa byo hejuru kandi byoroshye gukoresha ibicuruzwa bya RDP biteganijwe ko byiyongera mu bihe biri imbere.
