Umehluko phakathi kokunamathela kwesakhiwo nesimo sezulu-okunamathelayo okungazweli

Umehluko phakathi kokunamathela kwesakhiwo nesimo sezulu-okunamathelayo okungazweli

1. Ukusetshenziswa okuhlukile

Isimo sezulu-okunamathelayo ukumelana

1. Ifanele isimo sezulu-ukuvalwa okungazwani kwezindonga zamakhethini, okunconyelwe kakhulu isimo sezulu-ukuvalwa okungazwani kwezindonga zamakhethini engilazi, i-aluminium-izindonga zamakhethini zephaneli yepulasitiki kanye nokulengiswa okomile kwamatshe.
2. Ukuvala amalunga phakathi kwensimbi, ingilazi, i-aluminium, ithayela le-ceramic, i-plexiglass nengilazi eboshwe.
3. Amalunga okuvala kukhonkolo, usimende, amatshe, imabula, insimbi, ukhuni, i-anodized aluminium ne-aluminium ependiwe. Ezimweni eziningi, akukho primer edingekayo.

I-adhesive yesakhiwo

1. Isetshenziselwa ikakhulukazi ukuhlanganiswa kwesakhiwo noma okungezona-kwesakhiwo phakathi kwensimbi nengilazi yezindonga zamakhethini engilazi.
2. Ingakwazi ukuxhuma ngokuqondile ingilazi ebusweni bengxenye yensimbi ukuze yakhe ingxenye yomhlangano owodwa, ehlangabezana nezidingo zokuklama zezindonga zamakhethini ezifihliwe ngokugcwele noma uhlaka-ezicashile.
3. Ukuhlanganiswa kwesakhiwo nokuvalwa kwengilazi yokuvikela.

2. Indawo Yokwenza

Isimo sezulu-ama-sealant amelana kakhulu asetshenziselwa ukuvala izikhala phakathi kwezinto ezisetshenziswayo namajoyinti okuvikela amanzi; kuyilapho izinamathiselo zesakhiwo zisetshenziselwa ikakhulukazi ukuhlanganisa imihlangano yesakhiwo kanye nengeyona - yesakhiwo yezindonga zamakhethini ahlukahlukene. Zombili zinemisebenzi ehlukene.

3. Ukusebenza kokunamathela

1. Isimo sezulu-isivalisi esingazweli kungashiwo ukuthi siwuphawu oluvamile-lwenhloso, olumelana kakhulu nesimo sezulu esibi njengemisebe ye-ultraviolet, imvula ene-asidi, iqhwa, njll. Umthamo wokugudluzwa (okungahunyushwa ngokuthi ukunwebeka) kwesimo sezulu-isivalisi esingazweli siphezulu kunaleso se-sealant yesakhiwo.

2. Ngaphezu kwezici zesimo sezulu-ama-sealant angazweli, izinto zokunamathisela zesakhiwo ze-silicone nazo zinezimfanelo eziqinile zokubopha kunesimo sezulu-ama-sealant angezwani, ikakhulukazi ngokwamandla okudabuka, ukwelula ngesikhathi sekhefu, namandla aqinile. Amandla aqinile asetshenziswa kakhulu ezindaweni ezine-prestress. I-modulus, ubulukhuni, amandla kanye nentengo yezinto ezinamathelayo zesakhiwo ziphezulu kunalezo zesimo sezulu-ezinamathelayo ezingazweli zebanga elifanayo.

Isifinyezo: Ukumelana nesimo sezulu sokunamathela kwesakhiwo kuhle njengalokho kwesimo sezulu-okunamathelayo ukumelana, noma okungcono nakakhulu, ngoba ukumelana nesimo sezulu sokunamathela kwesakhiwo kuhlobene nokuphepha. Uma iguga ngokushesha, imiphumela yokuwa kwengilazi mibi kakhulu. Ngakho-ke, izinamathiselo zesakhiwo samanje ngokuyisisekelo ziyi-silicone (i-silicone adhesive), okuyinto ngokuyisisekelo engagugi endaweni yemvelo. Isimo sezulu-Ingcina eqinile ayibandakanyi ukuphepha, futhi umphumela wokwehluleka ngokuvamile ukuvuza kwamanzi nokuvuza komoya, ngakho-ke kunezinhlobo eziningi zesimo sezulu-izinto ezinamathelayo ezingazweli, okuhlanganisa i-polyurethane, i-polysulfide, i-acrylic, njll., kodwa i-silicone isengcono kakhulu ukumelana nesimo sezulu.
