Ụdị ntụ ntụ polymer a na-ejikarị eme ihe n'usoro ihe eji arụ ụlọ

Ngwa ngwa agwakọta akọrọ bụ ngwakọta nke ihe cimentious (ciment, uyi ofufe, slag ntụ ntụ, wdg), ihe nchịkọta dị mma pụrụ iche (aja quartz, corundum, wdg, na mgbe ụfọdụ na-achọ granules ọkụ, perlite gbasaa, gbasaa vermiculite, wdg). ) na admixtures na-agwakọta otu n'otu n'otu, na mgbe ahụ juru n'ọnụ na akpa, orù ma ọ bụ na-ọnọ na nnukwu na akọrọ ntụ ntụ ala dị ka ihe ụlọ.

E nwere ọtụtụ ụdị ngwa agha a na-ere ahịa, gụnyere ngwa ngwa ntụ ntụ maka masonry, ngwa ngwa ntụ ntụ maka plasta, ntụ ntụ ntụ maka ala, ngwa ngwa ntụ ntụ pụrụ iche maka mkpuchi mmiri, nchekwa ọkụ na ebumnuche ndị ọzọ.N'ịchịkọta, ngwa agha agwakọtara akọrọ nwere ike kewaa n'ime ngwa ngwa agwakọta akpọnwụ nkịtị (masonry, plastering and ground dry mixed mortar) na ngwa ngwa agwakọta akpọnwụ pụrụ iche.Ngwa ngwa agwakọta akọrọ pụrụ iche gụnyere: ngwa agha na-agbazi onwe ya, ihe ala na-eguzogide ọgwụ, onye na-ahụ maka caulking inorganic, ngwa agha na-egbochi mmiri, ngwa agha resin plasta, ihe nchebe elu elu, ngwa ngwa plasta na-acha, wdg.

Ya mere, ọtụtụ ngwa agha agwakọta akọrọ chọrọ admixtures nke ụdị dị iche iche na usoro dị iche iche nke ime ihe ka a ga-emepụta site na ọnụ ọgụgụ dị ukwuu nke ule.Tụnyere omenala ihe admixtures, akọrọ-agwakọta ngwa agha admixtures nwere ike na-eji na ntụ ntụ n'ụdị, na abuo, ha soluble na mmiri oyi, ma ọ bụ nke nta nke nta igbari n'okpuru edinam alkalinity na-egosipụta ha ruru mmetụta.

Uzuzu latex a na-emegharị emegharị na-abụkarị ntụ ntụ ọcha nwere mmiri mmiri kpọrọ nkụ, yana ọdịnaya ntụ nke ihe dịka 12%, ọdịnaya ntụ na-esite na onye na-ewepụta ya.The-ahụkarị urughuru size nke polymer ntụ ntụ bụ banyere 0.08mm.N'ezie, nke a bụ nha nke emulsion urughuru mkpokọta.Mgbe redispersing na mmiri, ahụkarị urughuru size nke emulsion urughuru bụ 1 ~ 5um.The-ahụkarị urughuru size nke emulsion ahụ na-eji kpọmkwem n'ụdị emulsion bụ n'ozuzu banyere 0.2um, otú ahụ urughuru size nke emulsion kpụrụ site polima ntụ ntụ bụ dịtụ nnukwu.Isi ọrụ bụ ịbawanye ike njikọ nke ngwa agha, melite ike ya, nrụrụ ya, nkwụsị mgbawa na enweghị ike, ma melite njide mmiri na nkwụsi ike nke ngwa agha.

Polymer redispersible polymer ntụ ntụ ugbu a na-eji akọrọ ntụ ntụ ngwa agha na-agụnye ndị a ụdị:

(1) styrene-butadiene copolymer;
(2) Styren-acrylic acid copolymer;
(3) vinyl acetate homopolymer;
(4) polyacrylate homopolymer;
(5) Styrene acetate copolymer;
(6) Vinyl acetate-etylene copolymer, wdg, ọtụtụ n'ime ha bụ vinyl acetate-etylene copolymer ntụ ntụ.
