Ime na mpụga mgbidi putty ntụ ntụ, tile nrapado, tile na-atụ gị n'ụlọnga, akọrọ ntụ ntụ interface n'ụlọnga, mpụga thermal mkpuchi ngwa agha maka mpụga mgbidi, onwe-leveling ngwa agha, idozi ngwa agha, ji achọ ngwa agha, waterproof ngwa agha mpụga thermal mkpuchi akọrọ-agwakọta ngwa agha.
N'ime ngwa agha ahụ, ọ bụ iji melite brittleness, akwa na-agbanwe modul na adịghị ike ndị ọzọ nke ngwa ngwa ciment omenala, na inye ciment ciment ka mma mgbanwe na ike njikọ ike, ka iguzogide na igbu oge ọgbọ nke ciment ngwa agha cracks.Ebe ọ bụ na polymer na ngwa agha na-etolite usoro netwọk interpenetrating, a na-emepụta ihe nkiri polymer na-aga n'ihu na pores, nke na-eme ka njikọ dị n'etiti nchịkọta na-egbochi ụfọdụ pores na ngwa agha ahụ, ya mere, ngwa agha a gbanwere mgbe ọ gbasiri ike dị mma karịa ngwa ngwa ciment.Enwere nnukwu ọganihu.
Ọrụ nke ntụ ntụ latex redispersable na putty bụ nke kachasị n'akụkụ ndị a:
1. Meziwanye adhesion na akụrụngwa nke putty.Redispersible latex ntụ ntụ bụ nrapado ntụ ntụ emere site na emulsion pụrụ iche (polima molecular dị elu) mgbe ihichachara.Nke a ntụ ntụ nwere ike ịgbasa ngwa ngwa n'ime emulsion mgbe ọ kpọtụrụ mmiri, ma nwee otu ihe ahụ dị ka emulsion mbụ, ya bụ, ọ nwere ike ịmepụta ihe nkiri mgbe mmiri kwụsịrị.Ihe nkiri a nwere nnukwu mgbanwe, elu ihu igwe na-eguzogide na iguzogide dị iche iche High adhesion na substrates.Tụkwasị na nke ahụ, uzuzu latex hydrophobic nwere ike ime ka ngwa agha ahụ bụrụ ihe na-adịghị mma.
2. Meziwanye njikọta nke putty, nguzogide dị mma, nguzogide alkali, na-eyi nguzogide, ma welie ike na-agbanwe agbanwe.
3. Meziwanye ihe mgbochi mmiri na permeability nke putty.
4. Meziwanye njide mmiri nke putty, mee ka oge na-emeghe, ma melite arụmọrụ.
5. Meziwanye nguzogide mmetụta nke putty ma welie ike nke putty.
2. Ọrụ nke redispersible latex ntụ ntụ na tile nrapado bụ tumadi na akụkụ ndị a:
1. Ka ọnụ ọgụgụ nke ciment na-abawanye, ike mbụ nke nrapado tile na-abawanye.N'otu oge ahụ, ike na-eme ka ọkpụkpụ na-egbuke egbuke mgbe imikpu n'ime mmiri na ike na-edozi ahụ mgbe ịka nká na-ekpo ọkụ na-abawanye.Ọnụ ego ciment kwesịrị ịdị n'elu 35%.
2. Na-abawanye nke ego nke redispersible latex ntụ ntụ, ike njikọ ike mgbe tetara na mmiri na tensile njikọ ike mgbe thermal ịka nká nke tile nrapado na-abawanye otú ahụ, ma tensile njikọ ike mgbe thermal ịka nká na-abawanye dịtụ doro anya.
3. Site na mmụba nke ọnụ ọgụgụ cellulose ether, ike nke ntanye nke tile adhesive mgbe ịka nká na-eme ka ọkụ na-abawanye, na ike na-edozi ahụ mgbe ọ gbasasịrị na mmiri na-ebu ụzọ na-abawanye ma na-ebelata.Mmetụta kachasị mma mgbe ọdịnaya cellulose ether dị gburugburu 0.3%.
Mgbe ị na-eji ntụ ntụ latex redispersible, anyị kwesịrị ịṅa ntị na ọnụọgụ ojiji, ka o wee nwee ike ịrụ ọrụ ya n'ezie.
