Iindlela zokuFakela i-Sealant ye-Structural Sealant kunye namanqaku oBugcisa aPhambili

Iimpawu zokutywinwa kwesakhiwo zizinto eziphambili zokudibanisa kunye nokutywinwa kumacandelo okwakha kunye nezoshishino. Ufakelo olululo luchaphazela ngokuthe ngqo ukuqina kunye nokhuseleko lwezakhiwo. Oku kulandelayo yinkqubo yokufakela esemgangathweni kunye namanqaku abalulekileyo obugcisa kwii-sealants zesakhiwo.

 

1. Unyango lwangaphambili

Ngaphambi kofakelo, coca ngokucokisekileyo umphezulu we-substrate ukususa ioli, uthuli, kunye nezinto ezikhululekileyo. Kwiindawo zetsimbi okanye zekhonkrithi, kucetyiswa ukuba usule nge-solvent (efana ne-isopropyl alcohol) kwaye usebenzise isixhobo se-sanding ukunyusa ukukhwabanisa ukuphucula amandla okubambisana. Ukuba ukufuma okanye ukungunda kukho, umphezulu kufuneka womiswe ngokupheleleyo kwaye ubulawe iintsholongwane.

2. Uyilo oludibeneyo kunye nesicelo se-Primer

Lungiselela amajoyinti afanayo (ngokuqhelekileyo 6-12mm ububanzi) ngokweemfuno zoyilo. Ubunzulu-ku{9}}ububanzi bomlinganiselo we-1:1 ukuya ku-2:1 uyacetyiswa. Kumphezulu{10}ophantsi{11}}imathiriyeli yamandla (efana ne-polytetrafluoroethylene), sebenzisa kwangaphambili i-primer ezinikeleyo kwaye uvumele ukuba zome kangangemizuzu emi-5-10 ukuqinisekisa ibhondi elungileyo.

3. Ukuxuba kunye nokusebenzisa i-Sealant

Ezimbini-izitywini ezitywiniweyo kufuneka zidityaniswe ngokuchanekileyo kwaye zishukunyiswe ngocoselelo ukunqanda amaqamza omoya avalelekileyo. -Into encamathelayo enye ingasetyenziswa ngokuthe ngqo. Sebenzisa umpu weglu ozinikeleyo ukugcwalisa amalungu okuncamathelisa ngesantya esingaguqukiyo, uqinisekisa ukuqhubeka, okugcweleyo, kunye neqamza{4}lomphezulu okhululekileyo. Kwimigangatho ethe nkqo, sebenzisa iglu ukusuka ezantsi ukuya phezulu ukunqanda ukugoba.

4. Ukucheba nokunyanga

Emva kokufaka isicelo, sebenzisa isixhobo esizinikeleyo (njenge-scraper) ukunqumla i-adhesive ibe yimo egudileyo, egobileyo. Nakuphi na ukugqithisa kufuneka kucocwe ngokukhawuleza. Ixesha lokunyanga lichatshazelwa bubushushu be-ambient kunye nokufuma; Amandla okuqala afikelela kwiiyure ezingama-24 kwaye unyango olupheleleyo lufumaneka kwiintsuku ezisi-7. Gwema ukuphazamiseka kwangaphandle okanye ukubonakaliswa kwamanzi ngeli xesha.

Amanyathelo okhuseleko: Abafaki-zicelo kufuneka banxibe iiglavu zokukhusela kunye neglavu ukuphepha ukudibana nolusu okanye amehlo. Gcina kwisikhongozeli esivaliweyo kude nokukhanya. Iqondo lokushisa elicetyiswayo liyi-5-25 degree.

Ukulandela ngokungqongqo la manyathelo kuya kuqinisekisa ukusebenza ngokufanelekileyo kwe-sealant yesakhiwo kunye nokwandisa ubomi besakhiwo sokwakha.
