Upende wokuvikela amanzi ophahleni lwechibi olungangeni manzi we-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
Ukuvikela uphahla
Uphahla oluyisicaba [Ukuvikela amanzi njalo ezitendini zemidlalo]
Inqubo yokwakha uphahla oluthambekile, isisekelo sethayela
- 1. Hlanza uthuli, lungisa indawo engaphansi ukuze ihlanzeke futhi icoceke. Uma kukhona amathayili aphakanyisiwe, ashintshiwe noma onakele, kudingeka abekwe kabusha. Amathayili aphukile nezindawo ezinezikhala ezinkulu kufanele ziphathwe ngeplasta ukuze zenze amathayili aqine futhi angakhululeki, futhi ahlangabezane nezimo zokwakha.
- 2. Thatha izinyathelo zokuzivikela, sebenzisa izikhwama zepulasitiki ukuvikela izinto ezisophahleni nasezindaweni ezizungezile, njengezibani zelanga, izintambo, amaphaneli elanga, izimoto, njll.
- 3. Faka/faka i-primer ekhethekile ye-polyurea ukuze uvale izikhala ezingaphezulu zesisekelo, wandise amandla okubopha phakathi kwezingqimba.
- 4. Futha izinto ezingangeni manzi ze-polyurea elastomer njengesendlalelo esiyisihluthulelo, ugxile ekuphatheni imininingwane efana nomugqa, amathayili aseceleni, amakhona, ama-gutter, ama-parapet, njll.
- 5. Faka/faka i-topcoat ekhethekile ye-polyurea, uyenze ibe yinhle, imelane nesimo sezulu, futhi ingashintshi umbala.
Ipaki Lamanzi
- 1. Ukwelashwa okuyisisekelo: Susa ungqimba lwesisekelo bese uveza 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 okumboza ngemuva kokufutha, futhi wandise ukunamathelana phakathi kwe-polyurea putty kanye ne-cement, umhlabathi wekhonkrithi. Linda kuze kube yilapho usupholile ngokuphelele ngaphambi kokuqhubekela esinyathelweni esilandelayo. Uma kukhona ukumhlophe okukhulu ngemva kokusetshenziswa, kudinga ukuphinda kufakwe kuze kube yilapho umhlabathi wonke ubonakala unsundu omnyama.
- 3. Ukusetshenziswa kwe-Polyurea putty: Faka i-polyurea special putty efanayo ngokulinganayo esisekelweni ukuze wandise ukuba yisicaba komhlabathi, uvale ama-capillary pores angabonakali ngeso lenyama, futhi ugweme isimo lapho i-polyurea efuthwe inezimbobo ezincane ngenxa yama-capillary pores asemhlabeni. Linda kuze kube yilapho ipholile ngokuphelele ngaphambi kokuqhubekela esinyathelweni esilandelayo.
- 4. Ukusetshenziswa kwe-polyurea primer: Faka i-polyurea primer ngokulinganayo ku-polyurea putty ephilisiwe ukuze wandise ngempumelelo ukunamathelana phakathi kwesendlalelo se-polyurea esifuthwe kanye ne-polyurea putty.
- 5. Ukusetshenziswa kwe-spray polyurea: Kungakapheli amahora angama-24 ngemuva kokwelashwa kwe-primer, sebenzisa imishini yokufutha yobungcweti ukuze ufafaze i-polyurea ngokulinganayo. Ubuso bengubo kufanele bube bushelelezi, kungabi nokugeleza 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.
