Kuputira kwePolyurea kunodzivirira ngura pamapaipi nematangi etsvina
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.
Munda wekudzivirira ngura ndipo pakatanga kushandiswa tekinoroji yepolyurea uye yakashandiswa zvakanyanya muinjiniya. Mashandisirwo ayo anosanganisira kudzivirira ngura yezvivakwa zvesimbi zvakaita semapaipi, matangi ekuchengetera zvinhu, madoko, mapombi esimbi, uye matangi ekuchengetera zvinhu zvemakemikari. Kufukidza kwacho kwakakora, hakuna musono, kune simba rakasimba rekudzivirira kupararira kwemvura uye ngura, kunogona kutsungirira kukanganiswa kwemakemikari akawanda, uye kunogona kushandiswa kwenguva yakareba munzvimbo dzekunze dzine ngura yakasimba senge madhamu, madziva, mafuta emunyu, nenzvimbo dzine matombo pasina hupfu, kutsemuka, kana kusvuuka. Inodzivirira mamiriro ekunze zvakanaka. Kuvhara kweDelsil polyurea anti-corrosion hakuzoputsiki kunyangwe paine kuchinja kwechimiro chesimbi, uye kunogona kufukidza nzvimbo yese yebasa kunyangwe mumamiriro asina kujairika akadai sekubuda kana kudzika kwemapaipi.
Maitiro ekuvaka
Tekinoroji Itsva Yekudzivirira Kuora Kwemadziva Etsvina
Sezvo mamiriro ekuchengetedza nharaunda achiwedzera kuipa, mvura yetsvina yemumaindasitiri, mvura yetsvina yekurapa, uye mushonga wemvura yemumaruwa zvese zvinoshandisa nzira yekuunganidza zvinhu zvakasiyana-siyana. Kudzivirira ngura mumadziva ekongiri kana mabhokisi esimbi ane tsvina yave chinhu chinonyanya kukosheswa. Zvikasadaro, zvichakonzera kubuda kwetsvina, zvichikonzera kusvibiswa kwevhu kusingagadzirisiki. Zvichienderana nehuwandu husina kukwana, hupenyu hwemadziva etsvina anodzivirira ngura hwakapetwa ka15 kupfuura hwemadziva etsvina asingadzivirire ngura. Zviri pachena kuti kudzivirira ngura mumadziva etsvina haisi chikamu chikuru chekuchengetedza nharaunda chete asiwo purofiti yakavanzwa kumabhizinesi.
- 1. Kukuya nekuchenesa pasi pevhu: Tanga watsvaira wozochenesa kuti ubvise guruva, mavara emafuta, munyu, ngura, uye zvinhu zvinoburitsa tsvina kubva pasi. Mushure mekukuya zvakanaka, unganidza guruva ne cleanser.
- 2. Kuvhara kweprimer isina solvent: Kunofanira kuiswa pamusoro pevhu usati wavaka. Kunogona kuvhara maburi emutsinga wepasi, kuderedza zvikanganiso zvekufukidza mushure mekupfapfaidza, uye kuwedzera kunamira pakati pekuvhara nepasi resimende nekongiri. Mirira kusvika yanyatsopora usati waenderera mberi nedanho rinotevera rekuvaka.
- 3. Rutivi rwekugadzirisa polyurea putty (rwakasarudzwa zvichienderana nemamiriro ekupfekwa): Shandisa polyurea patching putty yakagadzirirwa kugadzirisa nekuenzana. Mushure mekugadzika, shandisa vhiri remagetsi rekukuya kuti ugadzire zvakakwana wobva wabvisa vacuum cleaner.
- 4. Kuvhara primer isina solvent: Sanganisa primer isina solvent uye curing agent muchiyero chakatarwa, kurunga zvakaenzana, wobva wamonera kana kukwesha primer zvakaenzana mukati menguva yakatarwa yekushandisa. Vhara pamusoro pechigadziko wowedzera kunamira. Rega ipore kwemaawa 12-24 (zvichienderana nemamiriro epasi, nepfungwa yekuvhara pasi).
- 5. Pfapfaidza polyurea anti-corrosion coating; Mushure mekupasa piritsi rekuyedza, tanga wapfapfaidza buri rekubatanidza, wobva wapfapfaidza pamusoro pepombi, mapaipi akatwasuka kana magokora anopfapfaidzwa mufekitori, uye majoini anopfapfaidzwa panzvimbo yacho. Pfapfaidza nenzira kubva kumusoro kusvika pasi, wozobva waisa pasi, wofamba munzvimbo diki nenzira yakachinjika. Ukobvu hwepurasitiki i1.5-2.0mm. Pedzisa kupfapfaidza kamwe chete. Nzira dzakananga dzinogona kuwanikwa mu "Polyurea Engineering Coating Specifications".
- 6. Kumonera nekuisa polyurea top coat: Sanganisa chinhu chikuru chinosanganisa mushonga nechinhu chinosanganisa mushonga nechiyero chakatarwa, sanganisa zvakanaka, uye shandisa roller yakatsaurirwa kumonera nekushandisa muchina wekupfapfaidza kana kupfapfaidza kuti upfapfaidze polyurea top coat coat pamusoro pepolyurea coat coating yapora. Dzivisa mwaranzi ye ultraviolet, dzivirira kukwegura, uye shandura ruvara.
Kudzivirira Kuora Kwemapaipi
Mumakumi emakore achangopfuura, kwave nekuvandudzwa kukuru kwezvinhu zvekudzivirira ngura zvepaipi. Kubva pahurongwa hwekutanga hwekudzivirira ngura yemarasha kusvika kuhurongwa hwekudzivirira ngura yepurasitiki ye3PE, uye ikozvino kusvika kuzvinhu zvakagadzirwa nepolymer, mashandiro akawedzera zvakanyanya. Parizvino, nzira zhinji dzekudzivirira ngura dzine hunhu hwakadai sekuoma kwekuvaka, hupenyu hupfupi, kugadzirisa kwakaoma muchikamu chekupedzisira, uye kusashanda zvakanaka kwezvakatipoteredza. Kubuda kwepolyurea kwazadza mukaha uyu mumunda.
- 1. Kuputira jecha kubvisa ngura: Chekutanga, mapaipi anoputirwa jecha kuti abvise ngura zvichienderana nechiyero cheSa2.5. Maitiro ekuputika jecha anofanira kupedzwa mukati memaawa matanhatu. Zvadaro, pendi yepurasitiki inoiswa.
- 2. Kuisa primer: Mushure mekuputira jecha, primer isina solvent inoiswa. Kana primer yaoma kusvika yasara isina mvura yakajeka pamusoro, polyurethane coating inopfapfaidzwa. Iva nechokwadi chekuti yaiswa zvakaenzana kuti ive nechokwadi chekuti polyurethane nepaipi zvinobatana.
- 3. Kupfapfaidza nePolyurethane: Shandisa muchina wekupfapfaidza nepolyurethane kupfapfaidza polyurethane zvakaenzana kusvika ukobvu hwefirimu hwasvika. Pamusoro payo panofanira kunge pakanyatsotsvedzerera, pasina mvura inoyerera, maburi, maburi, kana kutsemuka. Kana paine kukuvara kwenzvimbo kana maburi, kugadzirisa nemaoko polyurethane kunogona kushandiswa pakupeta.
