I-polyurea anti-corrosion coating yamapayipi namathangi okuthuthwa kwendle
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.
Umkhakha we-anti-corrosion yilapho ubuchwepheshe be-polyurea bungene khona kusenesikhathi futhi busetshenziswe kabanzi kwezobunjiniyela. Izicelo zayo zihlanganisa ukunqanda ukugqwala kwezakhiwo zensimbi njengamapayipi, amathangi okugcina, amadokhu, izinqwaba zensimbi, namathangi okugcina amakhemikhali. Indwangu enamathelayo iminyene, ayinamthungo, inomphumela oqinile wokunqanda ukungena nokugqwala, ingamelana nokuguguleka kwemithombo yezindaba yamakhemikhali amaningi, futhi ingasetshenziswa isikhathi eside ezindaweni ezingaphandle ngokugqwala okuqinile njengamaxhaphozi, amachibi, uwoyela kasawoti, nezindawo ezinamatshe ngaphandle kokuvuthuluka, ukuqhekeka, noma ukuxebuka. Inokumelana nesimo sezulu esihle. I-Delsil polyurea anti-corrosion coating ngeke iphuke ngisho noma kukhona ukuwohloka esakhiweni sensimbi, futhi isengakwazi ukumboza yonke indawo yokusebenza ngisho nasezimeni ezingavamile ezifana nama-protrusions noma ukucindezelwa kwamapayipi.
Izinqubo zokwakha
Ubuchwepheshe Obusha Bokulwa Nokugqwala Kwamachibi Okukhucululwa Kwendle
Njengoba isimo sokuvikelwa kwemvelo siya siba sibi kakhulu, amanzi angcolile ezimbonini, amanzi angcolile ezokwelapha, nokwelashwa koketshezi lomquba wasemaphandleni konke kusebenzisa indlela yokuqoqa endaweni eyodwa. Ukunqanda ukugqwala kwamachibi kakhonkolo noma amabhokisi ensimbi aqukethe indle noma amanzi angcolile sekuyinto ehamba phambili. Uma kungenjalo, kuzodala ukuvuza kwesibili kwendle, okuholela ekungcoleni okungenakulungiseka komhlabathi. Ngokwezibalo ezingaphelele, impilo yesevisi yamachibi endle elwa nokugqwala iphindwe izikhathi ezingu-15 kunamachibi angenawo ukugqwala. Ngokusobala, ukulwa nokugqwala kwamachibi okukhucululwa kwendle akuyona nje ingxenye eyinhloko yezindawo zokuvikela imvelo kodwa futhi kuyinzuzo ecashile emabhizinisini.
- 1. Ukugaya nokuhlanza indawo engaphansi: Qala ngokushanela bese uhlanza ukuze ususe uthuli, amabala kawoyela, usawoti, ukugqwala, nezinto zokukhulula endaweni ephansi. Ngemuva kokugaya ngokuphelele, iqoqo lothuli lwe-vacuum.
- 2. Ukufakwa kwe-primer engancibiliki: Kufanele kusetshenziswe endaweni engaphansi ngaphambi kokwakhiwa. Ingakwazi ukuvala ama-capillary pores of surface floor, ukunciphisa ukukhubazeka kokumboza ngemva kokufafaza, futhi kwandise ukunamathela phakathi kokugqoka kanye nosimende nokhonkolo phansi. Linda kuze kube yilapho selapheke ngokugcwele ngaphambi kokudlulela esinyathelweni esilandelayo sokwakha.
- 3. I-polyurea putty yokulungisa isendlalelo (ekhethiwe ngokusekelwe ezimweni zokugqoka): Sebenzisa i-polyurea patching putty ukuze ulungise futhi ulinganise. Ngemva kokwelapha, sebenzisa isondo lokugaya likagesi ukuze ugaye ngokuphelele bese u-vacuum clean.
- 4. Ukuvalwa kwe-primer engancibiliki: Hlanganisa i-primer engancibiliki kanye ne-ejenti yokwelapha ngesilinganiso esinqunyiwe, gudluza ngokulinganayo, bese ugingqa noma usule i-primer ngokulinganayo phakathi nesikhathi esibekiwe sokusebenzisa. Vala indawo eyisisekelo futhi ukhulise ukunamathela. Vumela ukwelapha amahora angu-12-24 (kuye ngokuthi isimo sephansi, ngomgomo wokuvala phansi).
- 5. Futha i-polyurea anti-corrosion coating; Ngemva kokudlula isifutho sokuhlola, qala ngokufafaza imbobo yokuxhuma, bese ufafaza indawo engaphakathi yepayipi, amapayipi aqondile noma izindololwane zifafazwe efektri, futhi amalunga afafazwe esizeni. Fafaza ngokulandelana ukusuka phezulu ukuya phansi, bese uya phansi, bese uhamba endaweni encane ngephethini ephambene. Ubukhulu be-coating buyi-1.5-2.0mm. Qedela ukufutha ngesikhathi esisodwa. Izindlela eziqondile zingatholakala ku- "Polyurea Engineering Coating Specifications".
- 6. Ukugoqa bese ufutha ijazi eliphezulu le-polyurea: Hlanganisa i-ejenti eyinhloko kanye ne-ejenti yokwelapha ngesilinganiso esinqunyiwe, gudluza kahle, futhi usebenzise i-roller ezinikele yomshini wokugoqa noma umshini wokufutha ngokufafaza i-polyurea topcoat coat endaweni egcwele i-polyurea ehlanganiswe ngokugcwele. Melana nemisebe ye-ultraviolet, vimbela ukuguga, nokushintsha kombala.
I-Pipeline Corrosion Prevention
Emashumini eminyaka amuva nje, kube nentuthuko enkulu ezintweni zokuvimbela ukugqwala kwamapayipi. Kusukela ohlelweni lokuqala lokuvimbela ukugqwala kwetiyela lamalahle kuya ohlelweni lokuvimbela ukugqwala kwepulasitiki le-3PE, futhi manje kuya ezintweni eziyinhlanganisela ye-polymer, ukusebenza sekuthuthuke kakhulu. Njengamanje, izindlela eziningi zokuvimbela ukugqwala zinezici ezinjengobunzima bokwakha okuphezulu, isikhathi esifushane sokuphila, ukunakekelwa okunzima esigabeni sakamuva, kanye nobungane obumpofu bemvelo. Ukuvela kwe-polyurea kugcwalise lesi sikhala ensimini.
- 1. Ukuqhunyiswa kwesihlabathi ukuze kukhishwe ukugqwala: Okokuqala, amapayipi aqhunyiswa ngesihlabathi ukuze kukhishwe ukugqwala kuye ezingeni le-Sa2.5. Inqubo ye-sandblasting kufanele iqedwe phakathi namahora angu-6. Ngemuva kwalokho, i-polyurethane primer coating isetshenziswa.
- 2. Isicelo se-Primer: Ngemva kokuqhunyiswa kwesihlabathi, i-primer ekhethekile engena-solvent iyasetshenziswa. Ngemuva kokuthi i-primer yomile ibe yindawo lapho kungekho ketshezi olucacile oluhlala phezulu, i-polyurethane coating iyafafazwa. Qinisekisa ngisho nesicelo sokuqinisekisa ukunamathela phakathi kwe-polyurethane ne-substrate yepayipi.
- 3. Ukufafaza nge-polyurethane: Sebenzisa umshini wokufafaza we-polyurethane ukufafaza i-polyurethane ngokulinganayo kuze kufinyelelwe ukujiya kwefilimu. Ingaphezulu kufanele libe bushelelezi, ngaphandle kokugijima, izimbobo, amabhamuza, noma ukuqhekeka. Ngomonakalo wendawo noma amaphinikhodi, ukulungiswa kwe-polyurethane okwenziwa ngesandla kungasetshenziselwa ukuphetshwa.
