Redispersible polima ufa (RDP) ndi madzi sungunuka ufa polima emulsion. Izi zimagwiritsidwa ntchito kwambiri pantchito yomanga, makamaka ngati chomangira simenti ndi zida zina zomangira. Kulimba kwa mgwirizano wa RDP ndi gawo lofunikira kwambiri pakugwiritsa ntchito kwake chifukwa limakhudza mwachindunji katundu wa chinthu chomaliza. Chifukwa chake, ndikofunikira kukhala ndi njira yoyesera yolondola komanso yodalirika yoyezera mphamvu ya ma bond a RDP.
Njira Zoyesera
Zakuthupi
Zinthu zofunika kuchita mayesowa ndi izi:
1. Chitsanzo cha RDP
2. Mchenga wa aluminiyamu gawo lapansi
3. Pepala lopangidwa ndi utomoni (300um makulidwe)
4. Zomatira zamadzi
5. Makina oyezetsa zitsulo
6. Vernier caliper
pulogalamu yoyesera
1. Kukonza zitsanzo za RDP: Zitsanzo za RDP ziyenera kukonzedwa ndi kuchuluka kwa madzi oyenera monga momwe wopanga amanenera. Zitsanzo ziyenera kukonzedwa molingana ndi zofunikira zogwiritsira ntchito.
2. Kukonzekera kwa gawo lapansi: Gawo la aluminiyamu pambuyo pa sandblasting liyenera kutsukidwa ndikuumitsidwa musanagwiritse ntchito. Pambuyo poyeretsa, kuuma kwapamwamba kuyenera kuyesedwa ndi vernier caliper.
3. Kugwiritsa ntchito RDP: RDP iyenera kugwiritsidwa ntchito pagawo laling'ono malinga ndi malangizo a wopanga. Makulidwe a filimuyo ayenera kuyeza pogwiritsa ntchito vernier caliper.
4. Kuchiritsa: RDP iyenera kuchiza mkati mwa nthawi yomwe wopanga adauza. Nthawi yochiritsa imatha kusiyanasiyana kutengera mtundu wa RDP yomwe imagwiritsidwa ntchito.
5. Kugwiritsa ntchito pepala lopangidwa ndi utomoni: Pepala lopangidwa ndi utomoni liyenera kudulidwa kukhala mizere ya kukula ndi mawonekedwe oyenera. Mapepala amayenera kuphimbidwa mofanana ndi zomatira zamadzi.
6. Kumamatira kwa mapepala: Zingwe zomatira zomatira ziyenera kuikidwa pa gawo lapansi lokutidwa ndi RDP. Kupanikizika kopepuka kuyenera kugwiritsidwa ntchito kuti zitsimikizire kulumikizana koyenera.
7. Kuchiritsa: Zomatirazo ziyenera kuchiritsa mkati mwa nthawi yomwe wopanga adauza.
8. Kuyesa kwamphamvu: Kwezani chitsanzocho mu makina oyesera amphamvu. Mphamvu zolimba ziyenera kulembedwa.
9. Kuwerengera: Mphamvu ya mgwirizano wa RDP iyenera kuwerengedwa ngati mphamvu yofunikira kuti ilekanitse gawo laling'ono lopangidwa ndi RDP kuchokera pa tepi ya pepala yogawidwa ndi pamwamba pa gawo lapansi lophimbidwa ndi RDP.
Pomaliza
Njira yoyesera ndi njira yosavuta komanso yotsika mtengo yoyezera mphamvu ya bondi ya RDP. Njirayi ingagwiritsidwe ntchito pofufuza ndi mafakitale kuti awonetsetse kuti RDP ikugwira ntchito mu simenti ndi zipangizo zina zomangira. Kugwiritsa ntchito njirayi kungathandize kuwongolera kuwongolera komanso chitukuko chazinthu pantchito yomanga.
