Upende omelana nokuguguleka we-polyurea Izembozo zaphansi ze-polyurea
Incazelo Yomkhiqizo
Izembozo ze-polyurea zakhiwe kakhulu yizingxenye ze-isocyanate kanye nama-polyether amine. Izinto zokusetshenziswa zamanje ze-polyurea zihlanganisa kakhulu i-MDI, ama-polyol e-polyether, ama-polyamine e-polyether, izandisi ze-amine chain, izithasiselo ezahlukahlukene ezisebenzayo, ama-pigment kanye nama-filler, kanye ne-diluents esebenzayo. Izembozo ze-polyurea zinezici zesivinini sokupholisa esisheshayo, isivinini sokwakha esisheshayo, ukusebenza okuhle kakhulu kokulwa nokugqwala kanye nokusebenza okungangeni manzi, ububanzi bokushisa obubanzi, kanye nenqubo elula. Zifaneleka kakhulu emabhizinisini ahlukahlukene ezimboni kanye nawezimayini, izindawo zokupaka, izinkundla zemidlalo, njll., ukuze kufakwe phansi okunezidingo zokulwa nokushelela, ukulwa nokugqwala kanye nokumelana nokuguguleka.
IZICI ZOMKHIQIZO
- Ukumelana nokuguguleka okuphezulu, ukumelana nokuklwebheka, impilo yesevisi ende;
- Inokuqina okungcono kunephansi le-epoxy, ngaphandle kokuxebuka noma ukuqhekeka:
- I-coefficient yokungqubuzana kobuso iphezulu, okwenza ukuthi ingasheleli kakhulu kune-epoxy flooring.
- Ukwakheka kwefilimu enejazi elilodwa, ukomisa okusheshayo, ukwakhiwa okulula nokusheshayo:
- Ukuphinda ufake i-coating kunamathela kahle kakhulu futhi kulula ukukulungisa.
- Imibala ingakhethwa ngokukhululeka. Muhle futhi uyakhanya. Awunabo ubuthi futhi unobungani nemvelo.
Izinqubo zokwakha
Indawo Yokumisa Ezemidlalo
- 1. Ukwelashwa okuyisisekelo kwendawo: Susa uthuli, amabala kawoyela, amatshe aqoshiwe kasawoti, ukugqwala, kanye nezinto ezikhipha uthuli endaweni eyisisekelo ngokushanela kuqala bese uhlanza. Ngemva kokugaya kahle, kuqoqwa uthuli olungenawo umoya.
- 2. Ukusetshenziswa kwe-primer ekhethekile: Roll the primer ekhethekile ye-polyurea ukuze uvale ama-capillary pores, unciphise amaphutha okumboza, futhi wandise ukunamathelana phakathi kwe-polyurea coating kanye ne-base surface.
- 3. Ukupesha nge-polyurea putty (kuye ngesimo sokuguguleka kobuso besisekelo): Sebenzisa izinto ezikhethekile zokupesha ze-polyurea ukulungisa nokulinganisa ubuso besisekelo. Ngemva kokulungisa, sebenzisa isondo lokugaya likagesi ukuze uhlanze kahle bese usebenzisa i-vacuum cleaner ukuze uhlanze.
- 4. Roll sebenzisa i-primer ekhethekile ye-polyurea: Vala kabusha ubuso bomhlaba, ukhulise kakhulu ukunamathelana phakathi kwe-polyurea nesisekelo.
- 5. Futha i-polyurea waterproof coating: Ngemva kokuhlola i-spray, fafaza ngokulandelana ukusuka phezulu kuya phansi bese kuba phansi, uhamba endaweni encane ngendlela ephambeneyo neyinde. Ubukhulu be-coating bungu-1.5-2mm. Ukufutha kuqedwa ngesikhathi esisodwa. Izindlela ezithile zingatholakala ku-"Polyurea Engineering Coating Specifications". Idlala indima ebalulekile ekuvimbeleni ukungcola, ayigugi futhi ayishibiliki.
- 6. Futha/gingqa faka i-topcoat ekhethekile ye-polyurea: Hlanganisa i-ejenti eyinhloko kanye ne-ejenti yokwelapha ngokulingana, uvuselele kahle, bese usebenzisa i-roller ekhethekile ukuze ugingqa ngokulinganayo i-polyurea topcoat coating ebusweni be-polyurea coating obusuphelile. Imelana nemisebe ye-ultraviolet, ivimbela ukuguga nokushintsha kombala.
Iphansi le-workshop
- 1. Ukwelashwa kwesisekelo: Gaya ungqimba oluntantayo esisekelweni, uveze ubuso besisekelo esiqinile. Qinisekisa ukuthi isisekelo sifinyelela izinga lika-C25 noma ngaphezulu, siyisicaba futhi somile, asinalo uthuli, futhi asiphinde sihlanze. Uma kukhona ama-honeycombs, izindawo ezimahhadlahhadla, imifantu, njll., sebenzisa izinto zokulungisa ukuze usilungise futhi usilinganise ukuze uqinisekise ukuqina.
- 2. Ukusetshenziswa kwe-polyurea primer: Faka i-polyurea primer ekhethekile ngokulinganayo esisekelweni ukuze uvale ama-capillary pores ebusweni, uthuthukise isakhiwo somhlabathi, unciphise amaphutha embotsheni ngemva kokufutha, futhi wandise ukunamathelana phakathi kwe-polyurea putty kanye ne-cement, phansi kwekhonkrithi. Linda kuze kube yilapho ipholile ngokuphelele ngaphambi kokuqhubekela esinyathelweni esilandelayo sokwakha. Uma kunendawo enkulu yokuvezwa okumhlophe ngemva kokusetshenziswa, idinga ukuphinda ifakwe kuze kube yilapho yonke phansi ibukeka nsundu ngokumnyama.
- 3. Ukusetshenziswa kwe-Polyurea putty: Faka i-polyurea special putty efanayo ngokulinganayo esisekelweni ukuze wandise ukuthamba phansi, uvale ama-capillary pores angabonakali ngeso lenyama, futhi ugweme isimo lapho ukufafaza kwe-polyurea kubangela ama-pinholes ngenxa yama-capillary pores phansi. Linda kuze kube yilapho ipholile ngokuphelele ngaphambi kokuqhubekela esinyathelweni esilandelayo sokwakha.
- 4. Ukusetshenziswa kwe-polyurea primer: Ku-polyurea putty elungisiwe, sebenzisa i-polyurea primer ngokulinganayo ukuze wandise ukunamathelana ngempumelelo phakathi kwesendlalelo se-polyurea esifuthwe kanye ne-polyurea putty.
- 5. Ukwakhiwa kwe-polyurea yokufutha: Kungakapheli amahora angama-24 ngemuva kokwelashwa kwe-primer, sebenzisa imishini yokufutha yobungcweti ukuze ufafaze i-polyurea ngokulinganayo. Ubuso bengubo kufanele bube bushelelezi, kungabikho ukugeleza kwamanzi, imigodi, amabhamuza, noma ukuqhekeka; ngomonakalo wendawo noma imigodi, ukulungiswa kwe-polyurea ngesandla kungasetshenziswa.
- 6. Ukusetshenziswa kwe-polyurea topcoat: Ngemva kokuba ubuso be-polyurea bomile, faka i-polyurea topcoat ukuze uvimbele ukuguga, ukushintsha kombala, futhi uthuthukise ukumelana nokuguguleka kwe-polyurea coating, uvikele i-polyurea coating.
Imishini yokumba
- 1. I-substrate yensimbi, ukuqhumisa isihlabathi ukuze kususwe ukugqwala kufinyelela ezingeni le-SA2.5. Ubuso abunawo uthuli olungcolile, amabala kawoyela, njll. Kwenziwa ukwelashwa okuhlukene ngokwesisekelo.
- 2. Ukufutha nge-primer (ukuthuthukisa ukunamathela kwe-polyurea esisekelweni).
- 3. Ukwakhiwa kokufutha nge-polyurea (ungqimba oluyinhloko olusebenzayo lokuvikela. Ubukhulu ngokuvamile bunconywa ukuthi bube phakathi kuka-2mm no-5mm. Izinhlelo zokwakha ezithile zinikezwa ngokwemikhiqizo ehambisanayo).
- 4. Ukwakhiwa kokuxubha/ukufutha nge-topcoat (ukulwa nokuphuzi, ukumelana ne-UV, okwandisa izidingo zombala ezahlukahlukene).
