Ọ nwere ike njikọ pụtara ìhè, na-eme ka mgbanwe nke ngwa agha dịkwuo mma ma nwee ogologo oge mmeghe, na-enye ngwa agha ahụ ezigbo nguzogide alkali, ma na-eme ka adhesiveness, ike mgbanwe, mmiri na-eguzogide, plasticity na iyi mgbochi nke ngwa agha. Na mgbakwunye na ihe owuwu ihe owuwu, ọ nwere ike ime mgbanwe na ngwa agha mgbochi na-agbanwe agbanwe.
Mpaghara ngwa
1. Sistemụ mkpuchi ọkụ mgbidi dị n'èzí: ngwa agha ejikọtara ọnụ: Gbaa mbọ hụ na ngwa agha ahụ jikọtara mgbidi na bọọdụ EPS. Melite ike nkekọ. Ngwa ngwa plastering: iji hụ na ike arụ ọrụ, mgbape mgbawa na ịdịte aka nke sistemu mkpuchi ọkụ, yana nguzogide mmetụta.
2. Tile nrapado na onye na-ahụ maka ihe na-ekpo ọkụ: Tile adhesive: Nye njikọ dị elu maka ngwa agha, ma nye ngwa ngwa mgbanwe zuru oke iji mee ka ọnụọgụ mgbasawanye okpomọkụ dị iche iche nke mkpụrụ na seramiiki tile. Filler: Mee ka ngwa agha ahụ ghara imeri ya ma gbochie ntinye mmiri. N'otu oge ahụ, ọ nwere ezigbo adhesion na nsọtụ nke tile, obere shrinkage na mgbanwe.
3. Nrụzigharị tile na ihe nkedo osisi: Meziwanye ike nchikota na ike nke putty na ihe ndị pụrụ iche (dị ka ihe ndị dị na tile, mosaics, plywood na ndị ọzọ na-eji ire ụtọ), na hụ na putty nwere ezigbo mgbanwe iji mebie ọnụọgụ mgbasawanye nke ihe substrate. .
Nke anọ, ntinye mgbidi dị n'ime na nke dị n'èzí: melite ike njikọ nke putty iji jide n'aka na putty nwere mgbanwe ụfọdụ iji chekwaa mmetụta nke mgbasawanye dị iche iche na nrụgide mgbagwoju anya na-emepụta site na ọkwa dị iche iche. Gbaa mbọ hụ na putty nwere ezigbo nguzogide ịka nká, enweghị ike na mgbochi mmiri.
5. Ngwongwo ala na-edozi onwe ya: hụ na nha nha nke igwe na-agbanwe agbanwe nke ngwa agha na iguzogide ike na-ehulata na mgbawa. Melite nguzogide iyi, ike nkekọ na njikọta nke ngwa agha.
6. Interface ngwa agha: melite ike elu nke mkpụrụ ma hụ na njikọta nke ngwa agha ahụ.
7. Ngwunye mmiri na-ekpuchi mmiri nke ciment: hụ na arụ ọrụ mmiri na-adịghị mma nke mkpuchi mkpuchi mmiri, ma n'otu oge ahụ nwee ezigbo mmachi na isi ala iji meziwanye ike mkpakọ na mgbanwe nke ngwa agha ahụ.
8. Ndozi ngwa agha: hụ na ọnụọgụ mgbasawanye nke ngwa agha na ihe ndabere na-adaba, ma belata modul na-agbanwe nke ngwa agha. Jide n'aka na ngwa agha ahụ nwere ihe mgbochi mmiri zuru oke, ume iku ume na nrapado.
9. Masonry plasta ngwa agha: melite njigide mmiri. Na-ebelata mfu mmiri ka ọ bụrụ ihe ndị nwere porous. Meziwanye ịdị mfe nke ịrụ ọrụ ihe owuwu ma melite arụmọrụ ọrụ.
