I-polyurea anti-corrosion coating kwimibhobho kunye namatanki amdaka
Ingcaciso yeMveliso
Iingubo zePolyurea ziqulunqwe ikakhulu ngamacandelo e-isocyanate kunye ne-polyether amines. Iimathiriyeli ekrwada yangoku ye-polyurea ikakhulu ibandakanya i-MDI, i-polyether polyols, i-polyether polyamines, i-amine chain extender, izongezo ezisebenzayo ezahlukeneyo, ii-pigments kunye nezihluzi, kunye ne-diluents esebenzayo. Iingubo zePolyurea zineempawu zesantya sokunyanga ngokukhawuleza, isantya sokwakha ngokukhawuleza, i-anti-corrosion egqwesileyo kunye nokusebenza okungangeni manzi, uluhlu olubanzi lobushushu, kunye nenkqubo elula. Zifaneleke ngokukodwa kumashishini ahlukeneyo amashishini kunye nemigodi, iindawo zokupaka iimoto, amabala ezemidlalo, njl., Ukugquma umgangatho kunye neemfuno zokuchasa ukutyibilika, ukuchasana nokubola kunye nokuxhatshazwa kokugqoka.
IIMPAWU ZEMVELISO
- Ukumelana nokunxiba okuphezulu, ukunganyangeki, ubomi benkonzo obude;
- Inokuqina okungcono kunomgangatho we-epoxy, ngaphandle kokuxobuka okanye ukuqhekeka:
- I-coefficient yokukhuhlana komphezulu iphezulu, iyenza ikwazi ukumelana nokutyibilika kunomgangatho we-epoxy.
- Ukwenziwa kwefilimu enedyasi enye, ukomiswa ngokukhawuleza, ukwakhiwa okulula nokukhawulezayo:
- Ukuphinda kufakwe i-adhesion egqwesileyo kwaye kulula ukuyilungisa.
- Imibala inokukhethwa ngokukhululekileyo. Intle kwaye iqaqambile. Ayinatyhefu kwaye ayinabungozi kokusingqongileyo.
Intsimi ye-anti-corrosion apho iteknoloji ye-polyurea yangena ngokukhawuleza kwaye isetyenziswe ngokubanzi kubunjineli. Izicelo zayo ziquka i-anti-corrosion yezakhiwo zetsimbi ezifana nemibhobho, iitanki zokugcina, ii-docks, iimfumba zetsimbi, kunye neetanki zokugcina imichiza. I-coat material ixinene, ayinamthungo, inamandla okuchasana kunye nokusebenza kwe-corrosion, inokumelana nobuninzi bemichiza yemithombo yeendaba, kwaye ingasetyenziselwa ixesha elide kwiindawo ezingaphandle kunye ne-corrosion enamandla njengemigxobhozo, amachibi, ioli yetyuwa, kunye neendawo ezinamatye ngaphandle komgubo, ukuqhekeka, okanye ukuxobula. Inokumelana nemozulu entle. I-Delsil polyurea anti-corrosion coating ayiyi kuphuka nokuba kukho ukuguqulwa kwisakhiwo sentsimbi, kwaye isengakwazi ukugubungela yonke i-workpiece surface nakwiimeko ezingaqhelekanga ezifana neeprotrusions okanye ukudakumba kwemibhobho.
Iinkqubo zokwakha
ITekhnoloji eNtsha yokuChasa ukubola kwamachibi ogutyulo
Njengoko imeko yokhuseleko lokusingqongileyo iya isiba mandundu, amanzi amdaka avela kwimizi-mveliso, amanzi amdaka ezonyango, kunye nonyango lolwelo lomgquba wasemaphandleni zonke zamkela indlela yokuqokelela kwindawo enye. I-anti-corrosion ye-concrete pools okanye iibhokisi zetsimbi eziqulethe ugutyulo okanye amanzi amdaka ziye zaba yinto ephambili. Kungenjalo, kuya kubangela ukuvuza okwesibini kogutyulo, okukhokelela kungcoliseko olungenakulungiseka lomhlaba. Ngokweenkcukacha-manani ezingaphelelanga, ubomi benkonzo yamachibi ogutyulo achasene ne-corrosion amaxesha angama-15 kunamachibi ogutyulo angengawo achasene ne-corrosion. Ngokucacileyo, i-anti-corrosion of sewage pools ayiyona nje inxalenye engundoqo yezibonelelo zokukhusela indalo kodwa kunye nenzuzo efihliweyo kumashishini.
- 1. Ukugaya kunye nokucoca indawo engaphantsi: Qala ngokutshayela kwaye ucoce ukususa uthuli, amabala e-oyile, ityuwa, i-rust, kunye nee-agent zokukhulula kwindawo esezantsi. Emva kokusila ngokucokisekileyo, qokelela uthuli lwevacuum.
- 2. I-solvent-free primer coating: Kufuneka isetyenziswe kumhlaba ophantsi ngaphambi kokwakhiwa. Iyakwazi ukutywina i-capillary pores yomgangatho womgangatho, ukunciphisa iziphene zokugubungela emva kokutshiza, kunye nokwandisa ukunamathela phakathi kokugqoka kunye nesamente kunye nomgangatho wekhonkrithi. Lindela de uphile ngokupheleleyo phambi kokuba uqhubekele kwinqanaba elilandelayo lokwakha.
- 3. Umaleko wokulungisa i-polyurea putty (ekhethiweyo ngokusekelwe kwiimeko zokunxiba): Sebenzisa i-polyurea patching putty ezinikeleyo ukulungisa nokulinganisa. Emva kokunyanga, sebenzisa ivili lokusila lombane ukucola ngokupheleleyo kwaye emva koko ucoce.
- 4. Ukutywinwa kwe-solvent-free primer: Hlanganisa i-primer engena-solvent kunye ne-ejenti yokunyanga kwi-ratio emiselweyo, ugxobhoze ngokulinganayo, kwaye uqhube okanye ukhuhle i-primer ngokulinganayo kwixesha elichaziweyo lokusetyenziswa. Ukutywina umgangatho wesiseko kunye nokwandisa ukunamathela. Vumela ukunyanga iiyure ezingama-12-24 (kuxhomekeke kwimeko yomgangatho, kunye nomgaqo wokutywina umgangatho).
- 5. Tshaza i-polyurea anti-corrosion coating; Emva kokugqithisa uvavanyo lokutshiza, qala utshize umngxuma wokudibanisa, uze utshize indawo yangaphakathi yombhobho, imibhobho ethe tye okanye i-elbows ifafazwe kwifektri, kwaye amajoyina afafazwe kwisayithi. Ukutshiza ngokulandelelana ukusuka phezulu ukuya ezantsi, emva koko, kwaye uhambe kwindawo encinci kwipatheni yomnqamlezo. Ubukhulu bengubo yi-1.5-2.0mm. Gqibezela ukutshiza ngexesha elinye. Iindlela ezithile zinokufumaneka kwi "Polyurea Engineering Coating Specifications".
- 6. Ukugquma kwengubo kunye nokutshiza i-polyurea topcoat: Xuba i-arhente ephambili kunye ne-ejenti yokunyanga kumlinganiselo omiselweyo, ugxobhoze ngokucokisekileyo, kwaye usebenzise i-roller ezinikeleyo kwi-uniform rolling okanye umatshini wokutshiza wokutshiza i-polyurea yokugqoka i-coat kwi-polyurea enyangwa ngokupheleleyo. Ukuxhathisa imitha ye-ultraviolet, thintela ukuguga, kunye nokutshintsha kombala.
UThintelo lokuTyakala kwemibhobho
Kumashumi eminyaka akutshanje, kukho uphuhliso olubalulekileyo kwizinto zokuthintela ukubola kwemibhobho. Ukususela kwinkqubo yokuqala yokukhusela i-tar tar corrosion ukuya kwi-3PE yeplastiki yokukhusela i-corrosion system, kwaye ngoku ukuya kwizinto ezidibeneyo ze-polymer, ukusebenza kuphuculwe kakhulu. Okwangoku, uninzi lweendlela zokuthintela umhlwa zineempawu ezinjengobunzima bokwakha okuphezulu, ubomi obufutshane, ukugcinwa okunzima kwinqanaba lamva, kunye nokungalungelani kokusingqongileyo. Ukuvela kwe-polyurea kuzalise le sithuba kwintsimi.
- 1. I-Sandblasting yokususa i-rust: Okokuqala, imibhobho iqhunyiswa ngesanti ukuze kususwe i-rust kumgangatho we-Sa2.5. Inkqubo yokuqhunyiswa kwesanti kufuneka igqitywe kwiiyure ezi-6. Emva koko, i-polyurethane primer coating isetyenziswa.
- 2. Isicelo se-Primer: Emva kwe-sandblasting, i-primer ekhethekileyo ye-solvent-free primer isetyenziswa. Emva kokuba i-primer yomile kwindawo apho kungekho manzi acacileyo ahlala phezu komhlaba, i-polyurethane i-coating ifafazwa. Qinisekisa nokuba isicelo sokuqinisekisa ukunamathela phakathi kwe-polyurethane kunye ne-substrate yombhobho.
- 3. Ukutshiza i-polyurethane: Sebenzisa umatshini wokutshiza we-polyurethane ukutshiza i-polyurethane ngokulinganayo kude kube yimpumelelo yefilimu. Umphezulu kufuneka ube mpuluswa, ngaphandle kokubaleka, imingxunya, amaqamza, okanye ukuqhekeka. Ngomonakalo wendawo okanye i-pinholes, ukulungiswa kwe-polyurethane ye-manual ingasetyenziselwa ukudibanisa.
