Unoziva here? Munguva yechando, chisimbiso chechimiro chichaitawo sechecheche, zvichiita kutsamwa kuduku, saka ndeapi matambudziko achakonzera?
1.Structural sealant inorapa zvishoma nezvishoma
Dambudziko rekutanga iro kudonha kamwe kamwe kweambient tembiricha kunounza kune zvimiro zvesilicone sealants nderekuti vanonzwa kunonoka kurapa panguva yekushandisa. Iyo yekurapa maitiro echimiro chesilicone sealant ikemikari yekuita maitiro, uye tembiricha uye hunyoro kwezvakatipoteredza zvine imwe pesvedzero pakumhanya kwayo kwekurapa. Kune chimwe-chikamu chechimiro chesilicone sealants, iyo yakakwira tembiricha uye hunyoro, kukurumidza kukurumidza kurapa kunenge kuri. Mushure menguva yechando, kutonhora kunodonha zvakanyanya, uye panguva imwechete, nekunyorova kwakadzika, maitiro ekuporesa echisimbiso chemaitiro anokanganisa, saka kupora kwechisimbiso chekugadzirisa kunononoka. Mumamiriro ezvinhu akajairwa, kana tembiricha yakadzikira kupfuura 15 ℃, chiitiko chekunonoka kurapwa kwechimiro chisimbiso chiri pachena.
Mhinduro: Kana mushandisi achida kuvaka munzvimbo yakadzika tembiricha, zvinokurudzirwa kuita diki-nzvimbo glue bvunzo isati yashandiswa, uye kuita bvunzo yekunamatira peel kuratidza kuti chisimbiso chechimiro chinogona kuporeswa, kunamatira kwakanaka, uye chitarisiko hachisi dambudziko uye ipapo shandisa nzvimbo yakakura. Nekudaro, kana tembiricha yakadzika yakadzikira kupfuura 4 ° C, kuvakwa kweiyo structural sealant haikurudzirwe. Kana fekitori ine mamiriro ezvinhu, inogona kutariswa nekuwedzera tembiricha uye hunyoro hwenzvimbo iyo iyo structural sealant inoshandiswa.
2. Structural sealant bonding matambudziko
Nekuderera kwekushisa uye humidity, inoperekedzwa nekunonoka kurapa, kune zvakare dambudziko rekubatana pakati peiyo structural sealant uye substrate. Izvo zvinodikanwa zvekushandiswa kwezvigadzirwa zvekusimbisa sealant ndezvi: nzvimbo yakachena ine tembiricha ye10 ° C kusvika 40 ° C uye hunyoro hunoenderana ne40% kusvika 80%. Kupfuura zviri pamusoro apa zvishoma tembiricha zvinodiwa, kumhanya kwekubatanidza kunodzikiswa, uye nguva yekubatana zvizere kune substrate inowedzerwa. Panguva imwecheteyo, kana tembiricha yakadzikira, kunyorova kweadhesive uye pamusoro peiyo substrate kunoderera, uye panogona kunge paine mhute isingaoneki kana chando pamusoro peiyo substrate, iyo inokanganisa kunamatira pakati pechisimbiso chechimiro uye chisimbiso. substrate.
Solution: tembiricha yakadzikira pane yakaderera tembiricha yekuvaka yechimiro chisimbiso chisimbiso 10 ℃, iyo dhizaini dhizaini sealant bonding base zvinhu mune chaiyo yakaderera tembiricha yekuvaka nharaunda kuita bonding bvunzo, simbisa yakanaka bonding, uyezve kuvaka. Iyo fekitori yakajairira structural sealant, nekuvandudza tembiricha uye hunyoro hwenzvimbo yekushandisa yechimiro chisimbiso kukurumidza kuporeswa kwechimiro chisimbiso, asi zvakare inofanirwa kurebesa nguva yekurapa.
