I-polyurea engagqoki ngopende we-polyurea floor coatings
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
Isitendi Sezemidlalo
- 1. Ukwelashwa kwendawo okuyisisekelo: Susa uthuli, amabala kawoyela, amadiphozithi kasawoti, ukugqwala, futhi ukhulule izinto endaweni ephansi ngokushanela kuqala bese ukuhlanza. Ngemuva kokugaya ngokuphelele, kuqoqwa uthuli lwe-vacuum.
- 2. Isicelo esikhethekile se-primer: Roll sebenzisa i-primer ekhethekile ye-polyurea ukuze uvale ama-capillary pores, unciphise ukukhubazeka kokumboza, futhi ukwandise ukunamathela phakathi kwe-polyurea enamathela kanye nesisekelo sesisekelo.
- 3. Ukunamathisela nge-polyurea putty (kuye ngokuthi isisekelo sigqoke kanjani): Sebenzisa izinto ezikhethekile zokuchibiyela i-polyurea ukuze ulungise futhi ulinganise indawo engaphansi. Ngemuva kokupholisa, sebenzisa isondo lokugaya likagesi ukuze usihlabathi kahle bese usebenzisa isicoci se-vacuum ukuhlanza.
- 4. Roll sebenzisa i-primer ekhethekile ye-polyurea: Vala kabusha indawo engaphansi, ukwandisa kakhulu ukunamathela phakathi kwe-polyurea nesisekelo.
- 5. Fafaza i-polyurea engangeni manzi: Ngemva kokuhlola isifutho, fafaza ngokulandelana ukusuka phezulu ukuya phansi bese usuka phansi, uhamba endaweni encane ngephethini enqamulayo kanye nelongitudinal. Ubukhulu be-coating buyi-1.5-2 mm. Ukufafaza kuqedwa ngesikhathi esisodwa. Izindlela eziqondile zingatholakala ku- "Polyurea Engineering Coating Specifications". Idlala indima ebalulekile ekuvimbeleni amanzi, ayigugi futhi ayisheleli.
- 6. Fafaza/umqulu sebenzisa ijazi langaphezulu elikhethekile le-polyurea: Hlanganisa i-ejenti eyinhloko ne-ejenti yokwelapha ngokulingana, gudluza kahle, futhi usebenzise i-roller ekhethekile ukugoqa ngokulinganayo ijazi le-polyurea topcoat endaweni ehlanganiswe ngokuphelele ye-polyurea. Imelana nemisebe ye-ultraviolet, ivimbela ukuguga nokushintsha kombala.
Indawo yokusebenzela
- 1. Ukwelashwa kwesisekelo: Gaya ungqimba oluntantayo esisekelweni, uveze isisekelo esiqinile. 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 se-primer ngokulinganayo esisekelweni ukuze uvale ama-capillary pores ebusweni, uthuthukise isakhiwo somhlabathi, unciphise amaphutha embotsheni ngemva kokufafaza, futhi ukwandise ukunamathela phakathi kwe-polyurea putty kanye nosimende, phansi ukhonkolo. Linda kuze kube yilapho selapheke ngokugcwele ngaphambi kokudlulela esinyathelweni esilandelayo sokwakha. Uma kunendawo enkulu yokuchayeka okumhlophe ngemva kokufaka isicelo, idinga ukuphinda ifakwe kuze kube yilapho yonke iphansi ibonakala insundu ngokumnyama.
- 3. Isicelo se-polyurea putty: Faka i-polyurea ehambisanayo ye-putty ekhethekile ngokulinganayo esisekelweni ukuze ukwandise ukuqina phansi, uvale ama-capillary pores angabonakali ngeso lenyama, futhi ugweme isimo lapho ukufuthwa kwe-polyurea kubangela ama-pinholes ngenxa yama-capillary pores phansi. Linda kuze kube yilapho selapheke ngokugcwele ngaphambi kokudlulela esinyathelweni esilandelayo sokwakha.
- 4. Ukusebenzisa i-polyurea primer: Ku-polyurea putty eselashiwe, sebenzisa i-polyurea primer ngokulinganayo ukuze ukwandise ngempumelelo ukunamathela phakathi kongqimba olufafaziwe lwe-polyurea kanye ne-polyurea putty.
- 5. Fafaza ukwakhiwa kwe-polyurea: Phakathi namahora angu-24 ngemva kokuphulukiswa kwe-primer, sebenzisa imishini yokufafaza echwepheshile ukuze ufafaze i-polyurea ngokulinganayo. Ingaphezulu le-coating kufanele libe bushelelezi, ngaphandle kokugijima, izimbobo, ama-bubbles, 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.
Imishini yezimayini
- 1. I-Metal substrate, i-sandblasting yokususwa kokugqwala ifinyelela izinga le-SA2.5. Ingaphezulu alinawo uthuli olungcolile, amabala kawoyela, njll. Ukwelashwa okuhlukene kwenziwa ngokwesisekelo.
- 2. Ukufafaza kwe-Primer (ukuthuthukisa ukunamathela kwe-polyurea esisekelweni).
- 3. Ukwakhiwa kokufafaza kwe-polyurea (ungqimba oluyisivikelo oluyinhloko. Ubukhulu ngokuvamile bunconywa ukuthi bube phakathi kuka-2mm no-5mm. Izinhlelo ezithile zokwakha zinikezwa ngokusho kwemikhiqizo ehambisanayo).
- 4. Ukwakhiwa kwe-Topcoat yokuxubha/yokufafaza (i-anti-yellowing, ukumelana ne-UV, okwandisa izinhlobonhlobo zezidingo zombala).
