Silicone sealant yakakosha yekunamira, inonyanya kushandiswa kubatanidza akasiyana magirazi uye mamwe ma substrates. Inoshandiswa zvakanyanya muhupenyu hwemhuri, uye kune akawanda marudzi e-silicone sealants pamusika, uye kusimba kwechisungo chesilicone sealants kunowanzo kuratidzwa. Saka, sei kushandisa silicone sealant? Zvinotora nguva yakareba sei kuti silicone sealant irapwe?
Silicone sealant kushandiswa matanho
1.Bvisa unyoro, girisi, guruva uye zvimwe zvinosvibisa pamusoro pezvinhu. Pazvinenge zvakakodzera, shandisa zvinonyungudutsa (zvakadai sexylene, butanone) kuchenesa pamusoro, wobva washandisa dhende rakachena kupukuta zvisaririra zvose kuti zvinyatsochena nekuoma.
2.Kuvhara nzvimbo iri pedyo nekubatanidzwa ne tape yepurasitiki. Kuve nechokwadi chekuti mutsara webasa rekuisa chisimbiso wakakwana uye wakarongeka.
3.Cheka muromo wepombi yekuisa chisimbiso uye isa pombi yakanongedza. Zvadaro maererano nekukura kwekukonzera, inochekwa pa 45 ° Angle.
4.Isai pfuti yeglue uye shandisai glue zvinhu pamwe chete nekapu pa 45 ° Angle kuti uone kuti glue zvinhu zviri pedyo nepamusoro pezvinhu zvepasi. Kana iyo seam yakafara kupfuura 15 mm, inodzokororwa gluing inodiwa. Mushure mekubatanidza, cheka pasi nebanga kuti ubvise glue yakawandisa, uye wobvarura tepi. Kana pane mavara, abvise nemucheka wakanyorova.
5.sealant pakupisa kwekamuri mushure memaminitsi gumi ekuputika kwepamusoro, vulcanization yakakwana inotora maawa makumi maviri nemana kana kupfuura, maererano nehupamhi hwekuputira uye tembiricha uye hunyoro kwezvakatipoteredza.
Silicone sealant kurapa nguva
Silicone sealant yekunamatira nguva uye nguva yekurapa:
Silicone sealant kurapa maitiro anogadzirwa kubva kumusoro kusvika mukati, akasiyana maitiro echisimbiso pamusoro penguva yakaoma uye nguva yekurapa haina kufanana, saka kana iwe uchida kugadzirisa iyo yepamusoro inofanirwa kuitiswa sealant isati yaoma. Pakati pazvo, guruu yeasidhi uye guruu rinoonekera rakarerekera rinofanira kunge riri mukati memaminetsi mashanu kusvika gumi, uye glue rakasiyana-siyana rinofanirwa kunge riri mukati memaminitsi makumi matatu. Kana pepa rekuparadzanisa ruvara rinoshandiswa kuvhara imwe nzvimbo, mushure mekushandisa glue, inofanira kubviswa ganda risati raumbwa.
Iyo nguva yekurapa yesilicone sealant (pakamuri tembiricha ye20 ° uye humidity ye40%) inowedzera nekuwedzera kwekubatanidza ukobvu. Semuenzaniso, 12mm gobvu acid silicone sealant inogona kutora 3-4 mazuva kuseta, asi mukati memaawa makumi maviri nemana, iyo 3mm yekunze layer yapora. Kana nzvimbo iyo chisimbiso chinoshandiswa chiri chikamu kana chakavharwa zvachose, saka nguva yekurapa inotarirwa nekuoma kwechisimbiso. Muzviitiko zvakasiyana-siyana zvekubatana, kusanganisira mhepo isina mhepo, iyo yekubatanidza inofanirwa kutariswa zvizere pamberi pemidziyo yakasungwa isati yashandiswa. Mushonga unononoka pakudzika kwakadzika (pasi pe5 °) uye hunyoro (pasi pe40%).
