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.
Otu: Ọrụ nke uzuzu latex na-agbanwe agbanwe na putty bụ 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, ihe nkiri nwere ike ịmepụta mgbe mmiri na-ekpochapụ.Ihe nkiri a nwere nnukwu mgbanwe, elu ihu igwe na-eguzogide na iguzogide dị iche iche High adhesion na substrates.Tụkwasị na nke ahụ, hydrophobic latex ntụ ntụ 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.
Abụọ: Ọrụ nke ntụ ntụ latex na-agbanwe agbanwe na ngwa agha bụ akụkụ ndị a
1. Melite ike mkpakọ na ike mgbanwe nke ngwa agha.
2. Mgbakwunye nke latex ntụ ntụ na-eme ka ọnụ ọgụgụ elongation nke ngwa agha dịkwuo elu, si otú ahụ na-eme ka mmetụta siri ike nke ngwa agha dịkwuo mma, ma na-enyekwa ngwa agha ahụ na-enwe mmetụta mgbasawanye nrụgide.
3. Melite arụmọrụ nke ngwa ngwa.Usoro njikọ ahụ na-adabere na mgbasa ozi na mgbasa nke macromolecules n'elu nnyapade.N'otu oge ahụ, rọba ntụ ntụ nwere ụfọdụ permeability na n'ụzọ zuru ezu na-abanye n'elu ihe isi ihe na cellulose ether, nke mere na ihe ndị dị n'elu nke isi na plasta ọhụrụ dị nso, si otú ahụ na-emeziwanye Adsorption na-abawanye arụmọrụ ya.
4. Belata modul na-agbanwe nke ngwa agha, kwalite ikike nrụrụ ma belata ihe mgbawa.
5. Meziwanye ihe mgbochi nke ngwa agha.Ọganihu nke nguzogide iyi bụ tumadi n'ihi ịdị adị nke ụfọdụ nke gluu n'elu ngwa agha ahụ.Uzuzu gluu na-arụ ọrụ dị ka njikọ, na usoro omentum nke ntụ ntụ gluu na-eme nwere ike gafere n'oghere na mgbawa na ngwa ngwa ciment.Na-eme ka njikọ dị n'etiti ihe isi na ngwaahịa hydration ciment, si otú ahụ na-abawanye nguzogide eyi.
6. Nye ngwa agha ahụ magburu onwe ya nguzogide alkali.
Atọ: Ọrụ nke uzuzu latex na-agbanwe agbanwe na tile adhesives bụ akụkụ ndị a
1. Dị ka ọnụ ọgụgụ nke ciment na-abawanye, ike mbụ nke nrapado tile na-abawanye, ma n'otu oge ahụ, ike na-eme ka ọkpụkpụ na-eme ka ọ dị elu mgbe ọ na-emikpu 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 mmụba nke ọnụ ọgụgụ nke redispersible latex ntụ ntụ, ike njikọ ike nke tile nrapado mgbe imikpu n'ime mmiri na tensile bond ike mgbe okpomọkụ ịka nká na-abawanye otú ahụ, ma na-abawanye nke tensile bond ike mgbe okpomọkụ ịka nká dịtụ ala.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%.
Ya mere, mgbe ị na-eji ntụ ntụ latex redispersible, anyị ga-aṅa ntị na ego ejiri mee ihe, ka anyị wee nwee ike ịrụ ọrụ ya n'ezie.
