Pendi yekudzivirira mvura yePolyurea isina mvura
Tsananguro yeChigadzirwa
Mapurasitiki ePolurea anonyanya kuumbwa nezvinhu zveisocyanate uye mapolyether amines. Zvinhu zviripo pari zvino zvepolyurea zvinosanganisira MDI, polyether polyols, polyether polyamines, amine chain extenders, zvimwe zvinhu zvinoshanda, pigments uye fillers, uye active diluents. Mapurasitiki ePolurea ane hunhu hwekumhanya nekukurumidza, kukurumidza kuvaka, kudzivirira ngura uye kushanda kwemvura, kupisa kwakakura, uye maitiro ari nyore. Anonyanya kukodzera maindasitiri akasiyana-siyana uye migodhi, nzvimbo dzekupaka mota, nzvimbo dzemitambo, nezvimwewo, zvepurasitiki pasi zvine zvinodiwa zvekudzivirira kutsvedza, kudzivirira ngura uye kusakara.
ZVINHU ZVECHIGADZIRWA
- Kuramba kupfeka kwakanyanya, haikwenyi, uye hupenyu hwebasa hwakareba;
- Iine kusimba kuri nani pane epoxy flooring, isina kukwenya kana kutsemuka:
- Kukweshana kwepamusoro kwakanyanya, zvichiita kuti isatsvedze kupfuura epoxy flooring.
- Kugadzirwa kwefirimu rejasi rimwe chete, kuoma nekukurumidza, kuvaka kuri nyore uye nekukurumidza:
- Kupenda patsva kunonamira zvakanaka uye kuri nyore kugadzirisa.
- Mavara anogona kusarudzwa zvakasununguka. Akanaka uye anopenya. Haana chepfu uye haakuvadzi nharaunda.
Maitiro ekuvaka
Kudzivirira mvura padenga
Denga rakatsetseka [Kudzivirira mvura nguva dzose panzvimbo dzemitambo]
Maitiro ekuvaka denga rakatsetseka, nheyo dzemataira
- 1. Chenesa guruva, gadzirisa pasi kuti pave pakachena uye pakarongeka. Kana paine mataira akasimudzwa, akachinjwa kana akakuvara, anofanira kudzoserwa panzvimbo yawo. Mataira akaputsika nenzvimbo dzine mipata mikuru dzinofanira kupurwa neplastering kuti mataira acho ave akasimba uye asasununguke, uye akwane nemamiriro ekuvaka.
- 2. Tora matanho ekudzivirira, shandisa mabhegi epurasitiki kuchengetedza zvinhu zviri padenga nepamativi, zvakaita sema skylights, waya, solar panels, mota, nezvimwewo.
- 3. Pukuta/isa primer yakakosha yepolyurea kuti uvhare maburi epamusoro pechigadziko, uchiwedzera simba rekubatanidza pakati pezvikamu.
- 4. Pfafadzai zvinhu zvisingapindi mvura zve polyurea elastomer sechikamu chakakosha, muchitarisa pakubata zvinhu zvakaita semukwidza, mataira epadivi, makona, magata, maparapets, nezvimwewo.
- 5. Isa topcoat yakakosha yepolyurea, zvichiita kuti ive yakanaka, isingachinji mamiriro ekunze, uye isingachinji ruvara.
Paki yeMvura
- 1. Kugadzirisa kwekutanga: Bvisa slurry layer yebase woisa pachena nzvimbo yakaoma yebase. Iva nechokwadi chekuti foundation yasvika paC25 kana kupfuura, yakati sandara uye yakaoma, haina guruva, uye haidzokeri jecha zvakare. Kana paine huchi, nzvimbo dzisina kurongeka, mitswe, nezvimwewo, shandisa zvinhu zvekugadzirisa kugadzirisa uye kuienzanisa kuti ive nechokwadi chekuti inogara kwenguva refu.
- 2. Kuisa polyurea primer: Isa polyurea special primer zvakaenzana pahwaro kuti uvhare ma capillary pores epamusoro, simbisa chimiro chevhu, kuderedza zvikanganiso zvekufukidza mushure mekupfapfaidza, uye kuwedzera kunamira pakati pe polyurea putty nesimende, pasi pekongiri. Mirira kusvika yanyatsopora usati waenderera mberi nedanho rinotevera. Kana paine kuchena kwakanyanya mushure mekuisa, inofanira kuiswazve kusvika pasi rese raita brown yakasviba.
- 3. Kuisa Polyurea putty: Isa polyurea special putty inoenderana zvakaenzana pahwaro kuti iwedzere kutsvedza kwevhu, vhara ma capillary pores asingaonekwe nemaziso, uye dzivisa mamiriro ezvinhu apo polyurea yakapfapfaidzwa ine maburi madiki nekuda kwema capillary pores akagayiwa. Mirira kusvika yapora zvizere usati waenderera mberi nedanho rinotevera.
- 4. Kuisa polyurea primer: Isa polyurea primer zvakaenzana pa polyurea putty yakarapwa kuti iwedzere kubatana pakati pe polyurea layer yakapfapfaidzwa ne polyurea putty.
- 5. Kuisa polyurea mufiriji: Mukati memaawa makumi maviri nemana mushure mekupodzwa kweprimer, shandisa michina yekupfapfaidza yehunyanzvi kuti ufafadze polyurea zvakaenzana. Pamusoro pejira rinofanira kunge rakatsetseka, pasina mvura inoyerera, maburi, maburi, kana kutsemuka; kana paine kukuvara kwenzvimbo kana maburi, kugadzirisa polyurea nemaoko kunogona kushandiswa.
- 6. Kushandiswa kwePolyurea topcoat: Kana pamusoro pepolyurea paoma, isa polyurea topcoat kudzivirira kukwegura, kuchinja ruvara, uye kuwedzera kuramba kwekupfekwa kwepolyurea coat, zvichidzivirira polyurea coat.
