I-Polyurea yokugquma echibini lophahla lwepeyinti yokuthintela amanzi
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

- 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.
Iinkqubo zokwakha
Ukuthintela amanzi eluphahleni
Umphezulu wophahla oluthe tyaba [Ukuthintela amanzi ngendlela efanayo kwizitendi zezemidlalo]
Uphahla oluthambekileyo, inkqubo yokwakha isiseko sethayile
- 1. Uthuli olucocekileyo, lungisa umgangatho wesiseko ukuze ucoceke kwaye ucoceke. Ukuba kukho iileyile eziphakanyisiweyo, ezitshintshiweyo okanye ezonakalisiweyo, kufuneka ziphinde zibekwe. Iitayili eziphukileyo kunye neendawo ezinezikhewu ezinkulu kufuneka ziphathwe nge-plastering ukwenza iileyili ziqine kwaye zingakhululeki, kwaye zihlangabezane neemeko zokwakha.
- 2. Thatha amanyathelo okhuseleko, sebenzisa iingxowa zeplastiki ukukhusela izinto eziphezu kophahla najikelele, ezifana ne-skylights, iingcingo, iipaneli zelanga, iimoto, njl.
- 3. Umqulu usebenzise / usebenzise i-primer ekhethekileyo ye-polyurea ukutywina i-surface pores yesiseko, ukwandisa amandla okudibanisa i-interlayer.
- 4. Gcoba i-polyurea elastomer impahla engenamanzi njengoluhlu oluphambili, ugxininise ekuphatheni iinkcukacha ezifana ne-ridge, i-tiles side, iikona, i-gutters, i-parapets, njl.
- 5. Umqulu sebenzisa / sebenzisa i-topcoat ekhethekileyo ye-polyurea, iyenze ibe ntle, imelane nemozulu, kwaye ingatshintshi umbala.
Ipaki yamanzi
- 1. Unyango olusisiseko: Susa isiseko se-slurry layer kwaye uveze indawo enzima yesiseko. Qinisekisa ukuba isiseko sifikelela kwibakala le-C25 okanye ngaphezulu, sicaba kwaye somile, asinalo uthuli, kwaye asiphindi santi. Ukuba kukho ama-honeycombs, iindawo ezinqabileyo, iintanda, njl., ngoko sebenzisa izinto zokulungisa ukulungisa kunye nomgangatho wokuqinisekisa ukuqina.
- 2. Ukusetyenziswa kwe-polyurea primer: Faka isicelo se-polyurea ekhethekileyo ngokulinganayo kwisiseko sokutywina i-surface capillary pores, ukuphucula isakhiwo somhlaba, ukunciphisa iziphene zokugubungela emva kokutshiza, kunye nokwandisa ukunamathela phakathi kwe-polyurea putty kunye ne-samente, umhlaba wekhonkrithi. Linda de ibe ichache ngokupheleleyo phambi kokuba uqhubekele kwinyathelo elilandelayo. Ukuba kukho ukuqaqamba okubanzi emva kokufakwa kwesicelo, kufuneka kugalelwe kwakhona de umhlaba wonke ubonakale umdaka omnyama.
- 3. Ukusetyenziswa kwe-polyurea putty: Faka i-polyurea ehambelanayo ye-putty ekhethekileyo ngokulinganayo kwisiseko sokwandisa umhlaba, ukutywina i-capillary pores engabonakaliyo ngeso lenyama, kwaye ugweme imeko apho i-polyurea efafaziweyo ineepinhole ngenxa ye-capillary pores yomhlaba. Linda de ibe ichache ngokupheleleyo phambi kokuba uqhubekele kwinyathelo elilandelayo.
- 4. Ukusetyenziswa kwe-polyurea primer: Faka i-polyurea primer ngokulinganayo kwi-polyurea putty ephilisiwe ukuze ukwandise ngokufanelekileyo ukudibanisa phakathi kwe-polyurea efafaziweyo kunye ne-polyurea putty.
- 5. Tshiza isicelo se-polyurea: Kwiiyure ezingama-24 emva kokunyanga kwe-primer, sebenzisa izixhobo zokutshiza ngokulinganayo ukutshiza i-polyurea. Umphezulu wokwambathisa kufuneka ube mpuluswa, ngaphandle kokubaleka, imingxunya, amaqamza, okanye ukuqhekeka; ngomonakalo wendawo okanye i-pinholes, ukulungiswa kwe-polyurea ye-manual ingasetyenziswa.
- 6. Ukusetyenziswa kwe-polyurea topcoat: Emva kokuba umphezulu we-polyurea womile, sebenzisa i-polyurea topcoat ukukhusela ukuguga, ukuguqulwa kombala, kunye nokwandisa ukunyanzeliswa kwengubo ye-polyurea, ukukhusela i-polyurea yokugqoka.
