Gịnị bụ usoro nke omume nke redispersible polymer ntụ ntụ?

Usoro nke ime ihe na-emegharị polymer powders (RPP) gụnyere mmekọrịta ha na mmiri na akụkụ ndị ọzọ nke ngwa agha, na-eduga n'ịrụ ọrụ na ihe onwunwe.Nke a bụ nkọwa zuru ezu nke usoro omume nke RPP:

1. Mgbasa n'ime mmiri:
   • Emebere RPP ka ọ gbasaa ngwa ngwa na mmiri, na-emepụta nkwusioru colloidal kwụsiri ike ma ọ bụ ihe ngwọta.Nke a redispersibility dị oké mkpa maka ntinye ha n'ime ngwa ngwa usoro na hydration na-esote.
2. Nhazi ihe nkiri:
   • Mgbe agbasasịrị, RPP na-etolite ihe nkiri dị mkpa ma ọ bụ mkpuchi gburugburu akụkụ ciment na akụkụ ndị ọzọ nke matriks ngwa ngwa.Ihe nkiri a na-arụ ọrụ dị ka ihe nkedo, na-ejikọta ihe ndị ahụ na-eme ka njikọ dị n'ime ngwa agha dịkwuo mma.
3. Adhesion:
   • Ihe nkiri RPP na-eme ka adhesion n'etiti ngwa ngwa ngwa (dịka, simenti, aggregates) na ihe ndị dị n'elu ala (dịka ọmụmaatụ, ihe, masonry).Nke a emelitere nrapado na-egbochi delamination ma hụ na njikọ siri ike n'etiti ngwa agha na mkpụrụ.
4. Ndokwa mmiri:
   • RPP nwere akụrụngwa hydrophilic nke na-enyere ha aka ịbanye na idowe mmiri n'ime matriks ngwa ngwa.Mgbakwunye mmiri a na-abawanye na-agbatị hydration nke ihe simenti, na-eme ka arụ ọrụ dị mma, ogologo oge na-emeghe, na mma mmachi.
5. Mgbanwe na Ngbanwe:
   • RPP na-enye mgbanwe na ngbanwe na ngwa ngwa matriks, na-eme ka ọ bụrụ ihe na-eguzogide ọgwụ na mgbawa na nrụrụ.Mgbanwe a na-enye ohere ngwa ngwa nabata mmegharị nke mkpụrụ osisi na mgbasawanye / nkwekọrịta okpomọkụ na-emebighị iguzosi ike n'ezi ihe ya.
6. Ịrụ ọrụ emelitere:
   • Ọnụnọ nke RPP na-eme ka arụ ọrụ na nkwụsị nke ngwa agha dịkwuo mma, na-eme ka ọ dị mfe ịgwakọta, tinye, na ịgbasa.Nrụ ọrụ a kwalitere na-enye ohere maka mkpuchi ka mma yana ngwa otu, na-ebelata ohere nke oghere ma ọ bụ oghere na ngwa ngwa emechara.
7. Nkwalite ịdịte aka:
   • Ngwa agha ndị RPP emezigharịrị na-egosipụta ịdịte aka ka mma n'ihi nkwụsi ike ha na ihu igwe, ọgụ kemịkalụ, na abrasion.Ihe nkiri RPP na-arụ ọrụ dị ka ihe mgbochi nchebe, na-echebe ngwa agha ahụ site na ndị na-eme ihe ike n'èzí ma na-agbatị ndụ ọrụ ya.
8. Mwepụta ihe mgbakwunye na-achịkwa:
   • RPP nwere ike ikpuchi ma hapụ ihe ndị na-arụ ọrụ ma ọ bụ ihe mgbakwunye (dịka ọmụmaatụ, plasticizers, accelerators) n'ime matriks ngwa ngwa.Usoro ntọhapụ a na-achịkwa na-enye ohere maka ịrụ ọrụ ahaziri na usoro ahaziri iche iji mezuo ihe achọrọ ngwa ngwa.

Usoro nke ime ihe na-eme ka polymer powders redispersible gụnyere redisssion na mmiri, mmepụta ihe nkiri, nkwalite adhesion, njide mmiri, mgbanwe mgbanwe, nkwalite ọrụ, nkwalite ịdịte aka, na ntọhapụ a na-achịkwa nke ihe mgbakwunye.Usoro ndị a na-ejikọta ọnụ na-eme ka arụmọrụ dị mma na ihe onwunwe nke RPP gbanwetụrụ na ngwa ihe owuwu dị iche iche.
