I-polyurea anti-corrosion coating yemibhobho kunye neetanki zamanzi amdaka
Ingcaciso yeMveliso
Iingubo zePolyurea zenziwe ikakhulu zizinto ze-isocyanate kunye ne-polyether amines. Izinto ezisetyenziswayo ngoku ze-polyurea ziquka i-MDI, ii-polyol ze-polyether, ii-polyamine ze-polyether, izandisi ze-amine chain, izongezo ezahlukeneyo ezisebenzayo, ii-pigment kunye nezizalisi, kunye nee-diluents ezisebenzayo. Iingubo zePolyurea zineempawu zesantya sokulungisa ngokukhawuleza, isantya sokwakha esikhawulezayo, ukusebenza kakuhle kokulwa nokugqwala kunye nokusebenza okungangeni manzi, uluhlu olubanzi lobushushu, kunye nenkqubo elula. Zifanelekile ngokukodwa kumashishini ahlukeneyo emizi-mveliso kunye nemigodi, iindawo zokupaka, amabala emidlalo, njl.njl., zokugquma umgangatho oneemfuno zokungatyibiliki, ukuchasana nokugqwala kunye nokumelana nokuguguleka.
IIMPAWU ZEMVELISO
- Ukumelana nokuguguleka okuphezulu, ukumelana nokukrweleka, ubomi benkonzo obude;
- Iqine ngakumbi kunomgangatho we-epoxy, ngaphandle kokuxobuka okanye ukuqhekeka:
- I-coefficient yokungqubana komphezulu iphezulu, nto leyo eyenza ukuba ingatyibiliki ngakumbi kune-epoxy flooring.
- Ukwenziwa kwefilimu enengubo enye, ukomisa ngokukhawuleza, ulwakhiwo olulula nolukhawulezayo:
- Ukuphinda ufake i-coating kunamathela kakuhle kwaye kulula ukuyilungisa.
- Imibala ingakhethwa ngokukhululekileyo. Intle kwaye ikhanya. Ayinabungozi kwaye inobuhlobo nokusingqongileyo.
Intsimi yokulwa nokugqwala kulapho iteknoloji ye-polyurea yangena khona kwangethuba kwaye isetyenziswa kakhulu kubunjineli. Ukusetyenziswa kwayo kuquka ukulwa nokugqwala kwezakhiwo zentsimbi ezifana neepayipi, iitanki zokugcina, iidokhi, iinqwaba zentsimbi, kunye neetanki zokugcina iikhemikhali. Ugqumo lwezinto luxinene, alunamthungo, lunamandla okulwa nokugqwala, lunokumelana nokugqwala okuninzi, lunokumelana nokugqwala kobuninzi bezinto zamakhemikhali, kwaye lungasetyenziswa ixesha elide kwiindawo zangaphandle ezinomhlwa onamandla njengeemigxobhozo, amachibi, ioyile yetyuwa, kunye neendawo ezinamatye ngaphandle kokugutywa, ukuqhekeka, okanye ukuxobuka. Lunokumelana okuhle kwemozulu. Ugqumo lwe-Delsil polyurea oluchasene nokugqwala aluyi kwaphuka nokuba kukho ukuguquka kwisakhiwo sentsimbi, kwaye lusenokugubungela wonke umphezulu womsebenzi nangona kukho iimeko ezingaqhelekanga ezifana nokuvela okanye ukuxinana kwepayipi.
Iinkqubo zokwakha
Iteknoloji entsha yokulwa nokugqwala kwamachibi amdaka
Njengoko imeko yokhuseleko lokusingqongileyo isiba mandundu ngakumbi, amanzi amdaka emizi-mveliso, amanzi amdaka ezonyango, kunye nonyango lolwelo lomgquba wasemaphandleni zonke zisebenzisa indlela yokuqokelela kwindawo enye. Ukuchasana nokugqwala kwamachibi ekhonkrithi okanye iibhokisi zesinyithi ezine-lindle okanye amanzi amdaka kuye kwaba yinto ephambili. Ngaphandle koko, kuya kubangela ukuvuza kwesibini kwe-lindle, okubangela ungcoliseko olungenakuguqulwa lomhlaba. Ngokwezibalo ezingaphelelanga, ubomi benkonzo yamachibi e-lindle achasene nokugqwala buphindwe kalishumi elinesihlanu kunamachibi e-lindle angengawo achasene nokugqwala. Ngokucacileyo, ukuchasana nokugqwala kwamachibi e-lindle akusiyo nje inxalenye ephambili yezixhobo zokukhusela okusingqongileyo kodwa ikwayinzuzo efihliweyo kumashishini.
- 1. Ukugaya nokucoca isiseko: Qala ngokutshayela uze ucoce ukuze ususe uthuli, amabala eoyile, ityuwa, umhlwa, kunye nezinto ezikhupha izinto ezisisiseko. Emva kokusila kakuhle, qokelela uthuli nge-vacuum.
- 2. I-primer coating engenasombululo: Ifanele isetyenziswe kumphezulu womhlaba ngaphambi kokuba yakhiwe. Ingayivala imingxunya ye-capillary yomphezulu womgangatho, inciphise iziphene zokugquma emva kokutshiza, kwaye yonyuse ukunamathelana phakathi kwe-coating kunye nesamente kunye nomgangatho wekhonkrithi. Linda ide inyangeke ngokupheleleyo ngaphambi kokuba uqhubekele kwinqanaba elilandelayo lokwakha.
- 3. Umaleko wokulungisa i-polyurea putty (ukhethwe ngokweemeko zokuguguleka): Sebenzisa i-polyurea patching putty eyenzelwe ukulungisa nokulinganisa. Emva kokuyilungisa, sebenzisa ivili lokugaya ngombane ukuze uyigaye ngokupheleleyo uze uyicoce nge-vacuum cleaner.
- 4. Ukutywinwa kweprimer engenaso isinyibilikisi: Xuba iprimer engenaso isinyibilikisi kunye nearhente yokupholisa kwisilinganiso esimiselweyo, uxube ngokulinganayo, uze uqengqele okanye ukrwele iprimer ngokulinganayo kwixesha elichaziweyo lokusetyenziswa. Vala umphezulu wesiseko kwaye wongeze ukunamathela. Yivumele iphole iiyure ezili-12-24 (kuxhomekeke kwimeko yomgangatho, ngomgaqo wokutywina umgangatho).
- 5. Futha i-polyurea anti-corrosion coating; Emva kokudlula i-spray yovavanyo, qala ngokufutha umngxuma wokudibanisa, uze ufutha umphezulu wangaphakathi wombhobho, kutshizwe imibhobho ethe tye okanye iingqiniba efektri, kwaye amalunga atshizwe kwindawo leyo. Futha ngokulandelelana ukusuka phezulu ukuya ezantsi, uze utshize ezantsi, uze uhambe kwindawo encinci ngendlela enqamlezileyo. Ubukhulu be-coating yi-1.5-2.0mm. Gqibezela ukufutha ngaxeshanye. Iindlela ezithile zingafumaneka kwi-"Polyurea Engineering Coating Specifications".
- 6. Ukugoqa kunye nokutshiza i-polyurea top coat: Xuba i-arhente ephambili kunye ne-ejenti yokutshiza kwi-ratio emiselweyo, uxube kakuhle, kwaye usebenzise i-roller enikezelweyo kwi-rolling efanayo okanye umatshini wokutshiza ukutshiza i-polyurea top coat coat kumphezulu we-polyurea coating ovuthwe ngokupheleleyo. Melana nemisebe ye-ultraviolet, thintela ukwaluphala, kunye nokutshintsha kombala.
Ukuthintela Ukugqwala Kwemibhobho
Kwiminyaka yakutshanje, kubekho uphuhliso olukhulu kwizixhobo zokuthintela ukugqwala kwemibhobho. Ukususela kwinkqubo yokuqala yokuthintela ukugqwala kwetha yamalahle ukuya kwinkqubo yokuthintela ukugqwala kweplastiki ye-3PE, kwaye ngoku ukuya kwizixhobo zepolymer ezidityanisiweyo, ukusebenza kuye kwaphucuka kakhulu. Okwangoku, uninzi lweendlela zokuthintela ukugqwala zineempawu ezifana nobunzima obukhulu bokwakha, ixesha elifutshane, ukugcinwa okunzima kwinqanaba lokugqibela, kunye nokungabi nabuhlobo nokusingqongileyo. Ukuvela kwe-polyurea kuzalise esi sikhewu kwintsimi.
- 1. Ukuqhumisa isanti ukuze kususwe umhlwa: Okokuqala, imibhobho igqunywa isanti ukuze kususwe umhlwa ngokwemigangatho ye-Sa2.5. Inkqubo yokuqhumisa isanti kufuneka igqitywe zingadlulanga iiyure ezi-6. Emva koko, kufakwa i-polyurethane primer coating.
- 2. Ukusetyenziswa kwe-primer: Emva kokugquma isanti, kufakwa i-primer ekhethekileyo engenasombululo. Emva kokuba i-primer yomile ifikelele kwimeko apho kungekho manzi acacileyo ahlala phezu komphezulu, i-polyurethane coating iyatshizwa. Qinisekisa ukuba isetyenziswa ngokulinganayo ukuqinisekisa ukunamathelana phakathi kwe-polyurethane kunye ne-substrate yombhobho.
- 3. Ukutshiza nge-polyurethane: Sebenzisa umatshini wokutshiza nge-polyurethane ukutshiza i-polyurethane ngokulinganayo de kube ubukhulu befilimu bufikeleleke. Umphezulu kufuneka ube mtyibilizi, ungakhukulisi, ungabi nazimbobo, amaqamza, okanye ukuqhekeka. Kwimingxunya okanye imingxuma yendawo, ukulungiswa kwe-polyurethane ngesandla kungasetyenziselwa ukupeyinta.
