Ngwa 9 nke RDP na Mortar, anaghị efu

Polymer powders re-dispersible (RDP) bụ ụdị polima nke a na-ejikarị eme ihe n'ọtụtụ ngwa owuwu, gụnyere ngwa agha. A na-eme RDP site na ngwakọta nke polymers synthetic na ihe mgbakwunye, nke e mere iji melite arụmọrụ na ịdịte aka nke ngwa agha. Nke a bụ ngwa itoolu nke RDP na ngwa agha:

1. Ịrụ ọrụ emelitere: Enwere ike iji RDP mee ka arụ ọrụ nke ngwa agha dịkwuo mma site n'ịbawanye plasticity na nrụrụ ya. Nke a na-enye ohere ịgbasa ngwa agha ahụ ma tinye ya n'ọrụ ngwa ngwa, na-eme ka ọ dị nro na nke dị n'otu.
2. Njide mmiri ka mma: RDP na-enyekwa aka melite njide mmiri nke ngwa agha, nke dị mkpa maka ịhụ na ihe ahụ na-agwọta nke ọma. Mgbakwunye nke RDP na-enyere aka igbochi evaporation nke mmiri site na ihe onwunwe, na-eme ka usoro ọgwụgwọ na-agbanwe agbanwe na nke a na-ahụ anya.
3. Adhesion emelitere: RDP nwere ike imeziwanye mmachi nke ngwa agha na ihe dị iche iche, gụnyere kọnkịta, brik na nkume. Nke a dị mkpa maka ijide n'aka na ihe ahụ na-ejikọta nke ọma ma mepụta elu siri ike ma dịgidere.
4. Mbelata Mbelata: RDP na-enyere aka belata mbelata nke ngwa agha ka ọ na-akpọnwụ. Nke a dị mkpa n'ihi na mbelata nwere ike ịkpata mgbawa na elu na-enweghị isi, nke nwere ike imebi iguzosi ike n'ezi ihe nke ihe owuwu ahụ.
5. Mgbanwe dị mma: RDP nwere ike imeziwanye mgbanwe nke ngwa agha, nke dị mkpa maka igbochi mgbawa na mmebi nke ihe owuwu ndị a na-emegharị, dị ka ụlọ ndị dị na mpaghara ala ọma jijiji.
6. Mmegide Nkwụsị-Thaw emelitere: RDP nwere ike imeziwanye nkwụsi ike nke ngwa agha, nke dị mkpa maka ụlọ ndị ekpughere na ọnọdụ ihu igwe oyi na udu mmiri. Mgbakwunye nke RDP na-enyere aka igbochi mmiri ịbanye n'ime ihe ahụ ma kpatara mmebi.
7. Nguzogide mmetụta emelitere: RDP nwere ike imeziwanye nkwụsi ike nke ngwa agha, nke dị mkpa maka ụlọ ndị nwere nnukwu okporo ụzọ ma ọ bụ mmetụta. Mgbakwunye RDP na-enyere aka ịmịnye ujo nke mmetụta, na-ebelata ohere nke mmebi.
8. Mgbochi Abrasion emelitere: RDP nwekwara ike melite nguzogide abrasion nke ngwa agha, nke dị mkpa maka ihe owuwu ndị a na-eyi na akwa akwa, dị ka ala na ụzọ ụzọ. Mgbakwunye nke RDP na-enyere aka belata ọnụ ọgụgụ nke iyi na ihe onwunwe, na-agbatị ndụ ya.
9. Ọdịnaya Dị Mma: N'ikpeazụ, RDP nwere ike imeziwanye ogologo oge nke ngwa agha, nke dị mkpa maka ịhụ ogologo ndụ na nchekwa nke ihe owuwu. Mgbakwunye nke RDP na-enyere aka ịbawanye ike na nkwụsi ike nke ihe onwunwe, na-eme ka ọ dịkwuo ogologo oge na ogologo oge.

N'ikpeazụ, RDP bụ ihe dị mkpa na ngwa ngwa, na-enye ọtụtụ uru na ngwa. Ọ nwere ike imeziwanye arụmọrụ, njide mmiri, nrapanye, mbelata, mgbanwe, nkwụsi ike nke ifriizi, nguzogide mmetụta, nguzogide abrasion, na ịdịte aka, na-ebute ihe ndị siri ike na ntụkwasị obi. Mgbe ị na-ahọrọ RDP maka ngwa agha, ọ dị mkpa ịtụle ihe ndị dị ka ndakọrịta na ihe ndị ọzọ, nha nha, na njirimara arụmọrụ.
