Isembozo se-polyurea esilwa nokugqwala samapayipi namathangi endle
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.
Insimu yokulwa nokugqwala yilapho ubuchwepheshe be-polyurea buqale khona ekuqaleni futhi busetshenziswe kabanzi kwezobunjiniyela. Ukusetshenziswa kwayo kufaka phakathi ukulwa nokugqwala kwezakhiwo zensimbi ezifana namapayipi, amathangi okugcina, amadokodo, izinqwaba zensimbi, kanye namathangi okugcina amakhemikhali. Ukwembozwa kwezinto kuqinile, akunamthungo, kunamandla okulwa nokugqwala, kungamelana nokuguguleka kwemidiya yamakhemikhali amaningi, futhi kungasetshenziswa isikhathi eside ezindaweni zangaphandle ezinokugqwala okunamandla njengezindawo ezimanzi, amachibi, uwoyela kasawoti, kanye nezindawo ezinamadwala ngaphandle kokugqwala, ukuqhekeka, noma ukuxebuka. Kunokumelana okuhle nesimo sezulu. Ukwembozwa kwe-Delsil polyurea okulwa nokugqwala ngeke kuphuke ngisho noma kukhona ukuguguleka esakhiweni sensimbi, futhi kusengamboza yonke indawo yokusebenza ngisho nasezimweni ezingavamile njengokuvela noma ukugoba kwamapayipi.
Izinqubo zokwakha
Ubuchwepheshe Obusha Bokulwa Nokugqwala Kwamachibi Okungcola
Njengoba isimo sokuvikelwa kwemvelo siba sibi kakhulu, amanzi angcolile asezimbonini, amanzi angcolile ezokwelapha, kanye nokwelashwa koketshezi lomquba wasemakhaya konke kusebenzisa indlela yokuqoqwa okuhlanganisiwe. Ukulwa nokugqwala kwamachibi kakhonkolo noma amabhokisi ensimbi aqukethe indle noma amanzi angcolile sekuyinto eza kuqala. Ngaphandle kwalokho, kuzobangela ukuvuza kwesibili kwendle, okuholela ekungcoleni okungenakuguqulwa kwenhlabathi. Ngokwezibalo ezingaphelele, impilo yesevisi yamachibi angcolile okulwa nokugqwala iphindwe kayi-15 kuneyamachibi angcolile okulwa nokugqwala. Ngokusobala, ukulwa nokugqwala kwamachibi angcolile akuyona nje ingxenye eyinhloko yezindawo zokuvikela imvelo kodwa futhi kuyinzuzo efihliwe yamabhizinisi.
- 1. Ukugaya nokuhlanza phansi: Qala ngokushanela bese uhlanza ukuze ususe uthuli, amabala kawoyela, usawoti, ukugqwala, kanye nezinto ezikhipha uthuli ebusweni besisekelo. Ngemva kokugaya kahle, qoqa uthuli nge-vacuum.
- 2. I-primer coating engenaso isinyibilikisi: Kufanele ifakwe ebusweni bomhlaba ngaphambi kokwakhiwa. Ingavala izikhala ze-capillary ebusweni bomhlaba, inciphise amaphutha okumboza ngemva kokufutha, futhi yandise ukunamathelana phakathi kwe-coating kanye ne-cement kanye ne-concrete floor. Linda kuze kube yilapho ipholile ngokuphelele ngaphambi kokuqhubekela esinyathelweni esilandelayo sokwakhiwa.
- 3. Isendlalelo sokulungisa i-polyurea putty (esikhethwe ngokusekelwe ezimweni zokuguguleka): Sebenzisa i-polyurea patching putty enikezelwe ukulungisa nokulinganisa. Ngemva kokulungisa, sebenzisa isondo lokugaya likagesi ukuze ugxume ngokuphelele bese uhlanza nge-vacuum cleaner.
- 4. Ukuvalwa kwe-primer engenaso isinyibilikisi: Hlanganisa i-primer engenaso isinyibilikisi kanye ne-ejenti yokwelapha ngesilinganiso esibekiwe, uvuselele ngokulinganayo, bese ugoqa noma uklwebha i-primer ngokulinganayo phakathi nesikhathi esibekiwe sokusetshenziswa. Vala ubuso besisekelo bese wandisa ukunamathela. Yivumele iphole amahora angu-12-24 (kuye ngesimo sephansi, ngomgomo wokuvala phansi).
- 5. Futha i-polyurea anti-corrosion coating; Ngemva kokudlula i-spray yokuhlola, qala ngokufutha imbobo yokuxhuma, bese ufafaza ubuso bangaphakathi bepayipi, amapayipi noma izindololwane eziqondile ziyafuthwa efektri, bese kufefa amalunga endaweni. Futha ngokulandelana ukusuka phezulu kuya phansi, bese kuba phansi, bese uhamba endaweni encane ngendlela ephambene. Ubukhulu be-coating bungu-1.5-2.0mm. Qedela ukufutha ngesikhathi esisodwa. Izindlela ezithile zingatholakala ku-"Polyurea Engineering Coating Specifications".
- 6. Ukugoqa i-coating kanye ne-spray polyurea top coat: Hlanganisa i-ejenti eyinhloko kanye ne-curing agent ngesilinganiso esinqunyiwe, uvuselele kahle, bese usebenzisa i-roller ezinikele yomshini wokugoqa ofanayo noma wokufutha ukuze ufafaze i-polyurea top coating ebusweni be-polyurea coating obusuphelile ngokuphelele. Melana nemisebe ye-ultraviolet, vimbela ukuguga, kanye nokushintsha kombala.
Ukuvimbela Ukugqwala Kwepayipi
Emashumini eminyaka amuva nje, kube nentuthuko enkulu ezintweni zokuvimbela ukugqwala kwamapayipi. Kusukela ohlelweni lokuqala lokuvimbela ukugqwala kwetiyela lamalahle kuya ohlelweni lokuvimbela ukugqwala kwepulasitiki ye-3PE, futhi manje kuya ezintweni ezihlanganisiwe ze-polymer, ukusebenza kuthuthuke kakhulu. Njengamanje, izindlela eziningi zokuvimbela ukugqwala zinezici ezifana nobunzima obukhulu bokwakha, isikhathi esifushane sokuphila, ukulungiswa okunzima esigabeni sokugcina, kanye nobungane obubi bemvelo. Ukuvela kwe-polyurea kugcwalise lesi sikhala ensimini.
- 1. Ukuqhumisa isihlabathi ukuze kususwe ukugqwala: Okokuqala, amapayipi aqhumisa isihlabathi ukuze kususwe ukugqwala ngokwezinga le-Sa2.5. Inqubo yokuqhumisa isihlabathi kufanele iqedwe zingakapheli amahora ayi-6. Ngemuva kwalokho, kufakwa i-polyurethane primer coating.
- 2. Ukusetshenziswa kwe-primer: Ngemva kokuqhuma kwesihlabathi, kufakwa i-primer ekhethekile engenaso isinyibilikisi. Ngemva kokuba i-primer yomile kuze kube yilapho kungekho uketshezi olusobala oluhlala phezu kwayo, i-polyurethane coating iyafuthwa. Qinisekisa ukuthi isetshenziswa ngokulinganayo ukuqinisekisa ukunamathelana phakathi kwe-polyurethane kanye ne-substrate yepayipi.
- 3. Ukufutha nge-polyurethane: Sebenzisa umshini wokufutha nge-polyurethane ukuze ufafaze i-polyurethane ngokulinganayo kuze kube yilapho ifilimu iqina. Ubuso kufanele bube bushelelezi, kungabikho ukugeleza kwamanzi, imigodi, amabhamuza, noma ukuqhekeka. Uma kunomonakalo wendawo noma imigodi, ukulungiswa kwe-polyurethane ngesandla kungasetshenziswa ukupeyinta.
