Ọrụ nke redispersible polymer ntụ ntụ na putty ntụ ntụ

Ọrụ nkeredispersablepolymerntụ ntụna putty ntụ ntụ: ọ nwere ike adhesion na n'ibu Njirimara, pụtara ìhè waterproofness, permeability, na magburu onwe alkali iguzogide na eyi iguzogide, na ike melite mmiri njigide na-abawanye Open oge maka enwekwukwa anwụ ngwa ngwa.

1. Mmetụta nke ngwa agha agwakọta ọhụrụ

1) Meziwanye ihe owuwu.

2) Mgbakwunye mmiri na-ejide mmiri iji meziwanye hydration ciment.

3) Mee ka ọrụ rụọ ọrụ.

4) Zere mgbawa ngwa ngwa.

2. Mmetụta nke hardening ngwa agha

1) Belata modul na-agbanwe nke ngwa agha ma mee ka ndakọrịta na oyi akwa isi.

2) Mee ka mgbanwe dịkwuo elu ma gbochie mgbawa.

3) Meziwanye nguzogide ntụ ntụ na-ada.

4) Hydrophobic ma ọ bụ belata mmịpụta mmiri.

5) Mee ka adhesion na ala oyi akwa.

Uzuzu latex na-agbanwe agbanwe na-etolite emulsion polymer na kọntaktị na mmiri. N'oge ngwakọta na ihicha usoro, emulsion na-akpọnwụ ọzọ. Uzuzu latex na-arụ ọrụ na ntụ ntụ, na usoro nhazi usoro nhazi nke ciment hydration na latex powder film emechara na usoro anọ:

① Mgbe redispersible latex ntụ ntụ na- evenly weere na mmiri na putty ntụ ntụ, ọ na-agbasasị n'ime ezi polymer ahụ;

② A na-eji nwayọọ nwayọọ na-emepụta gel ciment site na hydration mbụ nke ciment, usoro mmiri mmiri jupụtara na Ca (OH) 2 nke a na-emepụta n'oge usoro hydration, na ihe ndị na-emepụta ihe na-emepụta polymer site na ntụ ntụ latex na-echekwa n'elu ciment gel / ngwakọta simenti na-adịghị edozi;

③ Ka simenti na-agbakwu mmiri, mmiri dị na pores capillary na-ebelata, na polymer na-eji nwayọọ nwayọọ na-ejikọta ya na pores capillary, na-eme ka oyi akwa na-ekpuchi elu nke ciment gel / unhydrated cement particle mix and filler;

④ N'okpuru omume nke hydration mmeghachi omume, isi oyi akwa absorption na elu evaporation, mmiri na-n'ihu belatara, na kpụrụ stacking n'ígwé na-agbakọta n'ime a mkpa film, na hydration mmeghachi omume ngwaahịa na-bonds ọnụ na-etolite a zuru ezu netwọk Ọdịdị. Usoro ngwakọta nke hydration ciment kpụrụ na nhazi ihe nkiri ntụ ntụ na-eme ka nguzogide mgbawa siri ike nke putty dịkwuo mma.

Site n'echiche nke ngwa bara uru, ike nke putty a na-eji dị ka oyi akwa mgbanwe n'etiti mkpuchi nke mpụga na mkpuchi nke mgbidi dị n'èzí ekwesịghị ịdị elu karịa nke nkedo nke plasta, ma ọ bụghị ya, ọ dị mfe ịmepụta mgbawa. N'ime usoro mkpuchi niile, mgbanwe nke putty kwesịrị ịdị elu karịa nke mkpụrụ. N'ụzọ dị otú a, putty nwere ike ime mgbanwe nke ọma na nrụrụ nke mkpụrụ ahụ ma chekwaa nrụrụ nke ya n'okpuru ọrụ nke ihe ndị dị na gburugburu ebe obibi, na-ebelata nchekasị nchekasị, ma belata ohere nke ịgbawa na peeling nke mkpuchi.
