unoziva here? Munguva yechando, structural sealant ichaitawo semwana, ichiita kutsamwa kuduku, saka ndeapi matambudziko achakonzera?
1.Structural sealant thickening
Structural sealants inozokora zvishoma nezvishoma uye kuita shoma mvura sezvo tembiricha inodzikira. Kune maviri-echikamu structural sealant, kukora kweiyo structural sealant kuchawedzera kumanikidzwa kweglue muchina uye kuderedza extrusion yechisimbiso chechimiro. Kune imwe-chikamu structural sealants, iyo structural sealant inokora, uye kudzvanywa kwepfuti yeglue kuti ibudise iyo structural sealant inowedzera, uye mashandiro emawoko anganzwa achitora nguva uye achinetsa.
Solution: Kana pasina mhedzisiro pakubudirira kwekuvaka, kuderera kwekushisa kwekushisa chinhu chakajairika, uye hapana matanho ekuvandudza anodiwa. Kana ikakanganisa kushanda kwekuvaka, unogona kufunga kuwedzera tembiricha yekushandiswa kwechisimbiso chechimiro kana kutora mamwe ekuwedzera ekudziya matanho, sekuchengeta chisimbiso chechimiro mukamuri yekudziya kana mhepo-inotonhorera pamberi. Isa kupisa mumusangano wegluing kuti uwedzere kupisa kwenzvimbo yegluing. Uye zvakare, iwe unogona kusarudza akakodzera glue maturusi, akadai semanyorero glue pfuti ine yakakwira thrust, pneumatic glue pfuti, yemagetsi glue pfuti, nezvimwe.
2.Weathering sealant bulges - kuonekwa kusina kufanana
Munguva yechando, musiyano wekushisa pakati pemasikati neusiku unowanzove wakakura. Kana yaiswa kumadziro ealuminium panel keteni, iyo inodzivirira mamiriro ekunze sealant inowanzoita bulging. Chikonzero chikuru ndechekuti kukurumidza kurapa kweiyo mamiriro ekunze-inodzivirira sealant inononoka munzvimbo yakaderera tembiricha, uye nguva inodiwa kuti nzvimbo irapwe kusvika pakadzika yakakwana ichave yakareba. Pamusoro pechisimbiso chinodzivirira mamiriro ekunze Kana kudzika kweglue kusati kwaporeswa zvakakwana, kana hupamhi hweglue seam hunosiyana zvakanyanya (izvi zvinowanzokonzerwa nekuwedzera kwekupisa uye kuputika kwepaneti), pamusoro pe glue seam ichakanganiswa uye kusaenzana kuchaonekwa. Mushure mekunge musono unonamira une nzvimbo isina kuenzana waporeswa, mukati mayo wakasimba, kwete mhango, izvo zvisingazokanganisa kuvharika kwenguva refu kweiyo mamiriro ekunze-resistant sealant, asi zvinongokanganisa kupfava kwechitarisiko chekunamatira.
Mushure menguva yechando, nzvimbo huru inotonhora, kutonhora kwakadzika, uye musiyano wekushisa pakati pemangwanani nemanheru wakakura. Nekuda kweiyo yakakura coefficient yemutsara wekuwedzera kwezvinhu, iyo aluminium pani yeketeni madziro inoremara zvakanyanya nekushisa. Pasi pemamiriro epamusoro ekuvaka sealant, pane imwe mukana wekuti glue majoini ealuminium pani reketeni madziro anoputika.
Solution:
1.Sarudza glue ine kukurumidza kukurumidza kuporesa, iyo inogona kuderedza zvine mwero dambudziko rekuputira kwemamiriro ekunze-resistant sealant.
2.Kana deformation yakabatana yeglue joint yakakura zvikuru nekuda kwekuderera kwehunyoro kana kusiyana kwekushisa, glue joint size, nezvimwewo, zvinokurudzirwa kusarudza imwe kana kupfuura nzira dzinotevera dzekuvaka.
a) Tora matanho akakodzera emumvuri, zvakadai sekudzivirira scaffolding neguruva-proof nets, kuitira kuti mapanera arege kuratidzwa zvakananga kune chiedza chezuva, kuderedza kutonhora kwemapuranga, uye kuderedza deformation yezvibatanidza zvinokonzerwa nekusiyana kwekushisa.
b)Edza kuronga gluing masikati, uye dzivisa kunama mangwanani nemanheru.
c) .Shandisa nzira yechipiri glue kushandiswa (ndiko kuti, kana pane concave glue musono mune yekutanga glue kushandiswa, inogona kurapwa kwemazuva maviri kusvika ku3, uye mushure mokunge iine elasticity, chikwata cheglue chinowedzerwa pa. pamusoro).
