Kuyinto jikelele, njengoba kugcizelelwe abasebenzisi, nokuthi futhi ingasetshenziswa imisebenzi ngaphakathi kanye nabangaphandle.

ukulungiselela Amathiphu ebusweni

Ngaphambi ukusebenzisa, omunye-ingxenye mastic kufanele uthintane usizo lobuchwepheshe mayelana ukupakisha izinto kwamanzi. Kumila kufanele uzilungiselele ngaphambili. On ikhava kungabikho iminonjana laitance, uthuli noma amafutha. Kubalulekile ukuba acabangele uhlobo ebusweni okwe zisebenzisa primer uma kunesidingo. Polyurethane sealant okumele asetshenziswe kuphela emva ukwelashwa surface nge sealant uma kukhona imifantu ngesisekelo ezingaphezu kuka-1 mm, ekhoneni amalunga omzimba noma ukunwetshwa amalunga omzimba. Zonke lezi amaphutha kungenziwa kalula wakhuzwa ngokwakho. Isicelo kusho ebusweni angamukelekile ababuthakathaka kumele uyeke ukusebenzisa uma amandla ngokhonkolo camera - engaphansi kuka-20 MPA. Ngo ukuqaliswa kwe-ungangenisi amanzi angaphakathi izakhiwo komhlaba kuqala kudingeka wenze ungangenisi amanzi okuhle.

izici lobuchwepheshe

Polyurethane sealant has Ukucaciswa ezithile, phakathi okuyinto - a ezisalayo ezomile of 95% kanye kwabantu ukuthi zokhahlamba kusuka 1.3 kuya 1.4 g / cm ^3. Kubalulekile ukuqaphela ukuthi ngezinye 20 ° C ukwakheka azigcina a viscosity kusuka 4.5 kuya 7.5 mPas. Kumiswa ifilimu ezingeni lokushisa +25 ° C futhi nomswakama ka 55% is ngokusebenzisa amahora angu-6 ngesikhathi kufakwa ungqimba yesibili iqhutshwa ngemva polymerization kufanele izigaba. Uthatha amahora 6 ukuze izinsuku. Ngokuphathelene inkathi ikhambi eliphelele, kuzokwenzeka ngemva kwezinsuku ezingu-7. Polyurethane mastic "Giperdesmo 'izilinganiso zazo okusesihlokweni esithi, kungenziwa eziqhutshwa ngesikhathi ububanzi lokushisa ububanzi okuyinto kuhluka -50 kuya +90 ° C. Uma uyikha phezulu le sokuqanjwa ngemva kokuphulukisa kungase zichazele ukuchayeka lokushisa ephakeme imizuzu 3. Lesi sengezo ongafinyelela +250 ° C. Ukuze abathengi professional kanye yangasese ipharamitha ezibalulekile ezifana ukugeleza ejenti, okulingana 1.3 kg / m ^2.

Izici isicelo

Ngemva ngokucophelela ebusweni ukulungiselela ungakwazi uqhubekele isicelo ze-mastic. Into yokuqala udinga mix. Ngenxa yale njongo kungcono ukusebenzisa stirrer Kuvunguza, ububanzi okuyinto 140 mm. Polyurethane ungangenisi amanzi mastic "Giperdesmo" kungase zixutshwe usebenzisa ukwakhiwa sokuprakthiza, ngenkathi kufanele isethelwe ku-200 ngomzuzu. Eshukumisayo kufanele uthathe cishe 4 imizuzu. Uma isicelo Kwenziwa ngesandla, kungcono ukusebenzisa le njongo enkulu Ibhulashi lokupenda, kufanele kube bristles iDemo elukhuni. Abanye bancamela roller nakatochny, kodwa kufanele kube isihlwathi iDemo. Ochwepheshe zisebenzisa isicelo ngomshini kule divayisi ingasetshenziswa spray airless, okuyinto yakhelwe ukusebenza nala makhemikhali kokuba viscosity okusezingeni eliphezulu.

isazi izincomo

Uma ungqimba lokuqala ifilimu kwenzeka, ungakwazi uqhubekele sicelo okwalandela.

Uma umsebenzi wenziwa ehlobo, kuzokwenzeka ngemva cishe amahora angu-8. enamathela okuqinile kuba ngemva kwezinsuku ezingu-7. Kubalulekile ukuqeda isicelo ngokweqile kwe-mastic. Kusendlalelo ngasinye okufanele sisetshenziselwe mayelana 0.7 kg. Uma sicabanga ngokweqile, lokho kungase kubangele ukubukeka Bubbles emhlabathini.
