Ngwa nke VAE RDP ntụ ntụ n'ime ngwa agha dị iche iche

1. Okwu mmalite:

Mmepe nke ihe eji ewu ụlọ emewo ka mmepe nke ihe mgbakwunye dịka polymer powders (RDP), nke na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ nke ụlọ ngwa agha.N'ime ụdị RDP dị iche iche, vinyl acetate-ethylene (VAE) RDP pụtara maka ịdị mma ya na ịdị irè ya n'ụdị ngwa agha dị iche iche.

2. Njirimara nke VAE RDP ntụ ntụ:

VAE RDP ntụ ntụ bụ copolymerized site na vinyl acetate na ethylene.Nke a na-emepụta ntụ ntụ dị mma, nke na-enweghị ihe ọ bụla nke nwere ezigbo dispersibility na mmiri.Ihe ndị dị mkpa nke VAE RDP gụnyere ike njikọ dị elu, ezigbo mgbanwe na ndakọrịta na ihe dị iche iche nke cimenti.Ngwongwo ndị a na-eme VAE RDP ka ọ bụrụ ihe mgbakwunye dị mma maka imeziwanye arụmọrụ nke ngwa agha ihe owuwu.

3. Ngwa nke VAE RDP dị iche iche na-ewu ngwa agha:

3.1.Ihe nrapado tile:

VAE RDP na-akwalite ike nkekọ na mgbanwe nke adhesives tile, na-ebute ike nkekọ na mbelata mgbawa.Ngwongwo ya na-ejigide mmiri na-enyekwa aka ịgbatị oge mmeghe, na-eme ka taịl nile dịkwuo mfe ịwụnye.

3.2.Sistemụ mkpuchi mgbidi na mpụga (EIFS):

Na EIFS, VAE RDP na-eme ka sistemu ahụ na-eguzogide mgbawa na ihu igwe.Ọ na-eme ka nrapanye nke primer na mkpụrụ osisi ahụ ma na-enye mgbanwe iji nabata mgbasawanye okpomọkụ na nkwekọrịta.

3.3.Nkwado nke onwe:

VAE RDP na-eme ka ihe na-asọpụta na nhazi onwe ya nke liner.Ọ na-eme ka ire ụtọ dị n'elu dịkwuo mma ma na-ebelata nkwụsịtụ, na-enye ntọala ndị ọzọ edo na nke na-adịgide adịgide maka mkpuchi ala.

3.4.Ngwakọta mmachi:

Na nrụzi ngwa agha, VAE RDP na-eme ka ike nkekọ na njikọta, na-eme ka ịdịte aka na ịrụ ọrụ ogologo oge nke nrụzi.Ọ na-enye aka melite arụmọrụ ma na-ebelata permeability, si otú ahụ na-eme ka nchebe mmiri dịkwuo elu.

4. Mmetụta nke VAE RDP na arụ ọrụ ngwa agha:

4.1.Ike adhesion:

VAE RDP na-eme ka ike njikọ dị n'etiti ngwa agha na mkpụrụ, na-ebute mgbakọ siri ike, na-adịgide adịgide.Ọ nwere ike ịmepụta ihe nkiri na-agbanwe agbanwe na interface iji welie adhesion n'okpuru ọnọdụ dị iche iche.

4.2.Ndokwa mmiri:

Ngwongwo na-ejigide mmiri nke VAE RDP na-agbatị usoro hydration ahụ, na-eme ka ọgwụgwọ dị mma ma melite akụrụngwa nke ngwa agha.Nke a na-eme ka arụmọrụ kachasị mma na ogologo oge dị ogologo, karịsịa na gburugburu ebe siri ike.

4.3.Njirimara rheological:

VAE RDP nwere ike ịgbanwe omume rheological nke ngwa agha, na-eme ka mmiri na-arụ ọrụ dịkwuo mma.Ọ na-ebelata ikewapụ na ọbara ọgbụgba mgbe ọ na-eme ka adhesion dịkwuo elu, na-eme ka ngwa ngwa dị mfe na nkwadebe elu dị mma.

VAE RDP ntụ ntụ na-egosi nnukwu ikike iji melite arụmọrụ nke ngwa agha dị iche iche.Ngwongwo ya pụrụ iche na-enyere aka melite ike nkekọ, njide mmiri na omume rheological, si otú ahụ na-ebuli usoro ngwa agha na ịkwalite ịdịte aka na ịrụ ọrụ.Site n'ịghọta ngwa nke VAE RDP n'ụdị ngwa agha dị iche iche, ndị na-arụ ọrụ nwere ike itinye uru ya iji nweta nsonaazụ ụlọ dị elu.
