I-Polyurea inxibe-resistant ipeyinti ye-polyurea yomgangatho
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.
Iinkqubo zokwakha
Ukuma kwezemidlalo
- 1. Unyango olusisiseko lwesiseko: Susa uthuli, amabala e-oyile, iidiphozithi zetyuwa, umhlwa, kunye neearhente zokukhulula ukusuka kumphezulu wesiseko ngokutshayela kuqala kwaye emva koko ucoce. Emva kokugaya ngokucokisekileyo, kuqokelelwa uthuli lwevacuum.
- 2. Isicelo esikhethekileyo se-primer: Umqulu usebenzisa i-primer ekhethekileyo ye-polyurea ukutywina i-capillary pores, ukunciphisa iziphene zokugubungela, kunye nokwandisa ukunamathela phakathi kwe-polyurea kunye nesiseko sesiseko.
- 3. Ukudibanisa nge-polyurea putty (kuxhomekeke kwimeko yokunxiba isiseko): Sebenzisa izinto ezikhethekileyo zokudibanisa i-polyurea ukulungisa kunye nomgangatho wesiseko. Emva kokunyanga, sebenzisa ivili lokusila lombane ukwenza isanti ngokucokisekileyo uze usebenzise isicoci ukucoca.
- 4. I-Roll isebenzise i-primer ekhethekileyo ye-polyurea: Vala kwakhona umhlaba ophantsi, ukwandisa kakhulu ukunamathela phakathi kwe-polyurea kunye nesiseko.
- 5. Tshaza i-polyurea yokugquma kwamanzi: Emva kokuvavanya isitshizi, sitshiza ngokulandelelana ukusuka phezulu ukuya ezantsi kwaye emva koko, uhamba kwindawo encinci kwipatheni enqamlezayo kunye ne-longitudinal. Ubukhulu bengubo yi-1.5-2mm. Ukutshiza kugqitywe ngexesha elinye. Iindlela ezithile zinokufumaneka kwi "Polyurea Engineering Coating Specifications". Idlala indima ephambili ekuthinteleni amanzi, ayigugi kwaye iyakwazi ukutyibilika.
- 6. Ukutshiza / umqulu sebenzisa i-topcoat ekhethekileyo ye-polyurea: Xuba i-arhente ephambili kunye ne-ejenti yokunyanga ngokulinganayo, ugxobhoze ngokucokisekileyo, kwaye usebenzise i-roller ekhethekileyo ukuze udibanise ngokulinganayo i-polyurea topcoat yokugqoka kwi-polyurea ephiliswe ngokupheleleyo. Ichasa imisebe ye-ultraviolet, ikhusela ukuguga kunye nokutshintsha kombala.
Umgangatho weworkshop
- 1. Unyango lweSiseko: Gcoba umaleko odadayo kwisiseko, uveze isiseko esiqinileyo. 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. Isicelo se-polyurea primer: Faka isicelo se-polyurea ekhethekileyo ngokulinganayo kwisiseko sokutywina i-capillary pores phezu komhlaba, uphucule isakhiwo somhlaba, unciphise iziphene kwi-coating emva kokutshiza, kwaye ukwandise ukunamathela phakathi kwe-polyurea putty kunye ne-samente, umgangatho wekhonkrithi. Lindela de uphile ngokupheleleyo phambi kokuba uqhubekele kwinqanaba elilandelayo lokwakha. Ukuba kukho indawo enkulu yokuvezwa okumhlophe emva kokufakwa kwesicelo, kufuneka iphinde isetyenziswe kuze kube yilapho wonke umgangatho ubonakala umnyama omnyama.
- 3. Isicelo se-polyurea putty: Faka i-polyurea ehambelanayo ye-putty ekhethekileyo ngokulinganayo kwisiseko sokwandisa umgangatho othe tyaba, utywine i-capillary pores engabonakaliyo ngeso lenyama, kwaye ugweme imeko apho ukutshizwa kwe-polyurea kubangela i-pinholes ngenxa ye-capillary pores emgangathweni. Lindela de uphile ngokupheleleyo phambi kokuba uqhubekele kwinqanaba elilandelayo lokwakha.
- 4. Ukusetyenziswa kwe-polyurea primer: Kwi-polyurea putty ephilileyo, sebenzisa i-polyurea primer ngokulinganayo ukuze ukwandise ngokufanelekileyo ukunamathela phakathi kwe-polyurea efafaziweyo kunye ne-polyurea putty.
- 5. Tshiza ulwakhiwo lwe-polyurea: Kwiiyure ezingama-24 emva kokunyanga kwe-primer, sebenzisa izixhobo zokutshiza ngokulinganayo ukutshiza i-polyurea. Ubuso bengubo kufuneka bube bushelelezi, ngaphandle kwe-run-off, pinholes, bubbles, okanye ukuqhekeka; ngenxa yomonakalo 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.
Izixhobo zemigodi
- 1. I-Metal substrate, i-sandblasting yokususwa kwe-rust ifikelela kwi-SA2.5 standard. Umphezulu awunalo uthuli longcoliseko, amabala e-oyile, njl njl. Unyango oluhlukeneyo lwenziwa ngokwesiseko.
- 2. I-primer yokutshiza (ukuphucula ukunamathela kwe-polyurea kwisiseko).
- 3. Ukwakhiwa kokutshiza i-Polyurea (umaleko oyintloko okhuselayo osebenzayo. Ubunzima ngokuqhelekileyo bunconywa ukuba bube phakathi kwe-2mm kunye ne-5mm. Izicwangciso ezithile zokwakha zinikezelwa ngokweemveliso ezihambelanayo).
- 4. I-Topcoat yokuxubha / ukwakhiwa kokutshiza (i-anti-yellowing, ukuchasana kwe-UV, ukwandisa iintlobo zeemfuno zombala).
