I-Polyurea enamanzi enamathela echibini lopende lokuvikela amanzi
Incazelo Yomkhiqizo
Izembatho ze-polyurea ikakhulukazi zakhiwe izingxenye ze-isocyanate nama-polyether amines. Izinto zamanje zokusetshenziswa ze-polyurea ikakhulukazi zihlanganisa i-MDI, i-polyether polyols, i-polyether polyamines, izandiso ze-amine chain, izithasiselo ezihlukahlukene ezisebenzayo, i-pigment kanye nezigcwalisi, nezihlanjululi ezisebenzayo. Izembatho ze-polyurea zinezici zejubane lokuphulukisa ngokushesha, isivinini sokwakha esisheshayo, ukusebenza kahle kakhulu kwe-anti-corrosion nokusebenza okungangeni manzi, ububanzi obubanzi bokushisa, kanye nenqubo elula. Zifaneleka ngokukhethekile amabhizinisi ahlukahlukene ezimboni kanye nezimayini, izindawo zokupaka, izinkundla zemidlalo, njll., Ukugqoka phansi okunezidingo zokulwa nokushelela, ukulwa nokubola kanye nokumelana nokugqoka.
IZICI ZOMKHIQIZO
- Ukumelana nokugqoka okuphezulu, ukumelana nokuklwebheka, impilo yesevisi ende;
- Inokuqina okungcono kune-epoxy flooring, ngaphandle kokuxebuka noma ukuqhekeka:
- I-surface friction coefficient iphezulu, iyenza imelane nokushelela kune-epoxy flooring.
- Ukwakhiwa kwefilimu yejazi elilodwa, ukomiswa okusheshayo, ukwakhiwa okulula nokusheshayo:
- Ukuhlanganisa kabusha kunokunamathela okuhle kakhulu futhi kulula ukukulungisa.
- Imibala ingakhethwa ngokukhululeka. Yinhle futhi iyakhanya. Ayinabuthi futhi ayihambisani nemvelo.
Izinqubo zokwakha
Ukuvikela amanzi ophahleni
Indawo yophahla oluyisicaba [Ukuvimbela amanzi okungaguquki ezitendi zezemidlalo]
Uphahla olushelelayo, inqubo yokwakha isisekelo sethayela
- 1. Hlanza uthuli, lungisa isisekelo ukuze uhlanzeke futhi ucoceke. Uma kukhona amathayili aphakanyisiwe, aguquliwe noma awonakele, adinga ukushintshwa. Amathayili aphukile kanye nezindawo ezinezikhala ezinkulu kufanele ziphathwe nge-plastering ukuze ama-tile aqine futhi angakhululeki, futhi ahlangabezane nezimo zokwakha.
- 2. Thatha izinyathelo zokuzivikela, sebenzisa izikhwama zepulasitiki ukuze uvikele izinto ezisophahleni nasezindaweni ezizungezile, njengama-skylights, izintambo, ama-solar panel, izimoto, njll.
- 3. Roll sebenzisa/sebenzisa i-primer ekhethekile ye-polyurea ukuze uvale izimbotshana ezingaphezulu zesisekelo, okwandisa amandla okubopha ama-interlayer.
- 4. Fafaza i-polyurea elastomer impahla engangeni manzi njengongqimba oluyisihluthulelo, ugxile ekuphatheni imininingwane efana ne-ridge, amathayela aseceleni, amakhona, ama-gutters, ama-parapets, njll.
- 5. Roll faka ijazi elikhethekile le-polyurea, ulenze libe lihle, limelane nesimo sezulu, futhi lingashintshi umbala.
Ipaki Yamanzi
- 1. Ukwelashwa okuyisisekelo: Susa isendlalelo se-slurry bese uveza indawo eqinile yesisekelo. Qinisekisa ukuthi isisekelo sifinyelela ebangeni elingu-C25 noma ngaphezulu, siyisicaba futhi somile, asinalo uthuli, futhi asiphindisi isihlabathi. Uma kukhona amakhekheba ezinyosi, izindawo ezimaholoholo, imifantu, njll., sebenzisa izinto zokulungisa ukuze uzilungise futhi uzilinganisele ukuze uqinisekise ukuqina.
- 2. Isicelo se-polyurea primer: Faka isicelo se-polyurea esikhethekile ngokulinganayo esisekelweni ukuze uvale ama-pores e-capillary ebusweni, uthuthukise isakhiwo somhlabathi, unciphise ukukhubazeka kokumboza ngemva kokufafaza, futhi ukwandise ukunamathela phakathi kwe-polyurea putty kanye nosimende, umhlabathi okhonkolo. Linda kuze kube yilapho selapheke ngokugcwele ngaphambi kokudlulela esinyathelweni esilandelayo. Uma kuba mhlophe okubanzi ngemva kokufakwa, kudingeka kusetshenziswe kabusha kuze kube yilapho yonke inhlabathi ibonakala insundu ngokumnyama.
- 3. Ukufakwa kwe-polyurea putty: Gcoba i-polyurea ekhethekile ye-putty ngokulinganayo phezu kwesisekelo ukuze ukwandise ukugcwala komhlabathi, vala izimbotshana ze-capillary ezingabonakali ngeso lenyama, futhi ugweme isimo lapho i-polyurea efafaziwe inezimbobo ngenxa ye-capillary pores yomhlabathi. Linda kuze kube yilapho selapheke ngokugcwele ngaphambi kokudlulela esinyathelweni esilandelayo.
- 4. Ukusebenzisa i-polyurea primer: Gcoba i-polyurea primer ngokulinganayo ku-polyurea putty ephulukisiwe ukwandisa ngempumelelo ukunamathela phakathi kongqimba lwe-polyurea efuthwe kanye ne-polyurea putty.
- 5. Futha nge-polyurea: Phakathi namahora angu-24 ngemva kokuphulukiswa kwe-primer, sebenzisa imishini yokufafaza echwepheshile ukuze ufafaze i-polyurea ngokulinganayo. Ingaphezulu lokumboza kufanele libe bushelelezi, ngaphandle kokugijima, izimbobo, amabhamuza, noma ukuqhekeka; ngomonakalo wendawo noma ama-pinholes, ukulungiswa kwe-polyurea manual kungasetshenziswa.
- 6. Isicelo se-polyurea topcoat: Ngemva kokuba i-polyurea surface yomile, sebenzisa i-polyurea topcoat ukuvimbela ukuguga, ukuguquguquka, futhi uthuthukise ukumelana nokugqokwa kwe-polyurea enamathela, ukuvikela i-polyurea coating.
