Kedu ụdị uzuzu polymer redispersible (RDP) dị?

Redispersible polymer powder (RDP) bụ ihe mgbakwunye polymer dị mkpa nke a na-eji eme ka arụ ọrụ nke ciment dabeere, gypsum, ihe ndị dabeere na lime na lime-mortar. RDP na-eme ka arụmọrụ zuru oke nke ihe ndị a dịkwuo mma site n'ịrụ ọrụ njikọ ya, nkwado, nkwụsị mgbape, mmiri na-eguzogide, wdg, ma na-ejikarị eme ihe n'ihe owuwu ụlọ.

Ụdị isi nke RDP

A na-ekekarị ụdị RDP dabere n'ụdị mkpụrụ nke ha mejupụtara, mpaghara ngwa na njirimara arụ ọrụ. RDP ndị a na-ahụkarị gụnyere ndị a:

Ethylene-vinyl acetate copolymer (EVA) ụdị:

Atụmatụ: Ethylene-vinyl acetate copolymer bụ otu n'ime ụdị RDP na-emekarị. Ọ nwere ezigbo mgbanwe na adhesion, ma na-enye ezigbo mmiri na-eguzogide na ihu igwe.
Ngwa: A na-ejikarị eme ihe na tile adhesives, ihe ndị na-edozi onwe ha, usoro mkpuchi mgbidi dị n'èzí na ubi ndị ọzọ.
Uru: Ọ na-enye ike siri ike na mgbanwe dị mma, dabara adaba maka oge ndị chọrọ mgbanwe ụfọdụ na adhesion.
Ọdịmma: N'ihi nnukwu ethylene ọdịnaya, arụmọrụ ya nwere ike ịbụ ntakịrị ezughi oke na ngwa ụfọdụ nwere nnukwu ike chọrọ.

Ethylene-vinyl acetate-vinyl acetate terpolymer (VeoVa/EVA) ụdị:
Atụmatụ: Ụdị RDP a na-ewebata VeoVa (vinyl ester) na ndabere nke ethylene na vinyl acetate copolymerization, nke na-eme ka mmiri na-eguzogide mmiri na nkwụsi ike nke ihe.
Ngwa: A na-ejikarị ihe mkpuchi mgbidi dị n'èzí na ngwaahịa gypsum, wdg.
Uru: Ọ nwere nguzogide mmiri ka mma na nguzogide kemịkalụ, dabara maka ngwa n'èzí na ngwa ike kemịkalụ.
Ihe ọghọm: E jiri ya tụnyere ụdị EVA ọdịnala, ọnụ ahịa ya nwere ike ịdị elu karịa.

Ụdị Styren-butadiene copolymer (SB):
Atụmatụ: Ọ na-abụkarị nke styrene na butadiene monomers, ma nwee ezigbo njikọ njikọ, mgbanwe na nkwụsị mmiri.
Ngwa: A na-ejikarị na tile adhesives na mgbanwe putties.
Uru: Ezigbo njikọ na mgbanwe, yana arụmọrụ dị mma na nguzogide mmiri.
Ọdịmma: Enwere ike ịka nká n'okpuru ìhè ultraviolet.

Vinyl acetate-etylene copolymer (VAE) ụdị:
Atụmatụ: Ọ bụ copolymer nke vinyl acetate na ethylene, nke nwere ezigbo mgbanwe na nguzogide mmiri.
Ngwa: Ọ dabara adaba maka adhesives tile, sistemu mkpuchi mgbidi dị n'èzí, gypsum dabere na ọkwa onwe onye, ​​wdg.
Uru: Ọ na-enye ezigbo adhesion na mmiri na-eguzogide, ma nwee ụfọdụ nguzogide kemịkal.
Ọdịmma: Ọnụ ego ahụ dị oke elu.

Ụdị acrylic copolymer (acrylic):
Atụmatụ: Isi akụrụngwa bụ acrylic ester, nke nwere ezigbo nrapado na mgbanwe.
Ngwa: A na-ejikarị ya eme ihe eji achọ mma, akwa tile, gypsum na ihe ndị ọzọ.
Uru: Adhesion kacha mma na mgbanwe, yana ezigbo nguzogide UV.
Ihe ọghọm: N'ihi ọnụ ahịa dị elu nke ihe acrylic, ọnụ ahịa ụdị RDP a dịkwa elu.

Ọrụ na ngwa nke RDP

Ịrụ ọrụ njikọta emelitere:
RDP na-arụ ọrụ nchịkọta n'ime ihe ahụ, na-eme ka adhesion nke nrapado na-eme ka ọ dịkwuo mma, ma na-eme ka njikọ dị n'etiti ihe owuwu ụlọ na mkpụrụ.
Mpaghara ngwa gụnyere ihe nrapado taịlị, ngwa agha njikọta, wdg.

Mgbanwe mgbanwe na nkwụsị mgbawa: Site n'ịgbakwunye RDP, mgbanwe nke ihe ahụ na-eme ka ọ dịkwuo mma, nke na-enyere aka igbochi nkwụsị nke mgbagwoju anya.
A na-ejikarị eme ihe na sistemu mkpuchi, putty na-agbanwe agbanwe, ihe ndozi, wdg.

Emelitere nguzogide mmiri na nguzogide mmiri:
RDP na-eme ka mmiri na-eguzogide ihe dị mma, na-enye ya ohere ịnọgide na-arụ ọrụ kwụsiri ike na gburugburu iru mmiri.
A na-etinye ya na mkpuchi mmiri, mkpuchi mgbidi dị n'èzí, wdg.

Ịrụ ọrụ ụlọ emelitere:
RDP nwere ike imeziwanye arụmọrụ ihe owuwu nke ihe ntụ ntụ akọrọ, na-eme ka owuwu dị mfe ma dị irè karị.
A na-eji ya eme ihe n'ụzọ nke onwe ya, ihe mkpuchi, wdg.

Ọganihu dị mma na nguzogide ihu igwe: N'ihi mgbakwunye nke RDP, ịdịte aka na nguzogide ihu igwe nke ihe na-eme ka ọ dịkwuo mma, ọ pụkwara iguzogide ule nke gburugburu ebe obibi siri ike.
Tinyere na usoro mgbidi dị n'èzí, mkpuchi ụlọ, wdg.

Atụmatụ maka ịhọrọ RDP kwesịrị ekwesị

Ọnọdụ ngwa:
Họrọ ụdị RDP kwesịrị ekwesị dabere na ọnọdụ ngwa a kapịrị ọnụ, dịka ọmụmaatụ, ngwa n'èzí chọrọ RDP nwere ezigbo nguzogide ihu igwe.

Njikwa ọnụ ahịa:
N'ihe gbasara ijide n'aka ịrụ ọrụ, ọ dị mkpa iji tụlee ụgwọ ihe onwunwe ma họrọ RDP akụ na ụba.

ndakọrịta:
RDP kwesịrị ịkwado nke ọma na ihe ndị ọzọ iji hụ na nkwụsi ike na arụmọrụ nke ngwakọta.

Achọrọ ịrụ ọrụ:
Họrọ ụdị RDP kwesịrị ekwesị dị ka ihe ndị achọrọ (dị ka mgbanwe, adhesion, mgbochi mmiri, wdg).

Uzuzu latex na-agbanwe agbanwe na-arụ ọrụ dị mkpa n'ime ihe owuwu nke oge a, ụdị ya dị iche iche na-enye ihe ngwọta na-agbanwe agbanwe maka mkpa ihe owuwu dị iche iche. Ịhọrọ ụdị RDP kwesịrị ekwesị nwere ike ime ka arụ ọrụ nke ihe ụlọ dịkwuo mma, si otú a na-eme ka mma na ịdịte aka nke ọrụ ihe owuwu dị.
