Ipeyinti engagugiyo yePolyurea Iingubo zomgangatho zePolyurea
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.
Iinkqubo zokwakha
Indawo yokuma yezemidlalo
- 1. Unyango olusisiseko lomphezulu: Susa uthuli, amabala eoyile, iityuwa ezigciniweyo, umhlwa, kunye nezinto ezikhupha izinto kumphezulu osisiseko ngokutshayela kuqala uze emva koko ucoce. Emva kokusila kakuhle, kuqokelelwa uthuli olungenamthungo.
- 2. Ukusetyenziswa kweprimer ekhethekileyo: Roll faka iprimer ekhethekileyo ye-polyurea ukuze uvale ii-capillary pores, unciphise iziphene zokugquma, kwaye wonyuse ukunamathelana phakathi kwe-polyurea coating kunye nomphezulu wesiseko.
- 3. Ukupeyinta nge-polyurea putty (kuxhomekeke kwimeko yokuguguleka komphezulu wesiseko): Sebenzisa izinto ezikhethekileyo zokupeyinta ze-polyurea ukulungisa nokulinganisa umphezulu wesiseko. Emva kokuwucoca, sebenzisa ivili lokugaya ngombane ukuze ucoce kakuhle uze usebenzise i-vacuum cleaner ukucoca.
- 4. Roll sebenzisa i-primer ekhethekileyo ye-polyurea: Vala kwakhona umphezulu womhlaba, wonyusa kakhulu ukunamathelana phakathi kwe-polyurea kunye nesiseko.
- 5. Futha i-polyurea engangeni manzi: Emva kokuvavanya i-spray, fafaza ngokulandelelana ukusuka phezulu ukuya ezantsi uze emva koko uhambise indawo encinci ngendlela enqamlezileyo neyobude. Ubukhulu be-coating yi-1.5-2mm. Ukufutha kwenziwa ngexesha elinye. Iindlela ezithile zingafumaneka kwi-"Polyurea Engineering Coating Specifications". Idlala indima ephambili ekuthinteleni amanzi, ayigugi kwaye ayityibiliki.
- 6. Futha/qengqa faka i-topcoat ekhethekileyo ye-polyurea: Xuba i-arhente ephambili kunye ne-curing agent ngokulinganisela, uxube kakuhle, kwaye usebenzise i-roller ekhethekileyo ukuqengqa ngokulinganayo i-polyurea topcoat coating kumphezulu we-polyurea coating osele upholile. Iyamelana nemisebe ye-ultraviolet, ithintela ukwaluphala kunye nokutshintsha kombala.
Umgangatho weworkshop
- 1. Unyango lwesiseko: Sika umaleko odadayo kwisiseko, uveze umphezulu wesiseko oqinileyo. Qinisekisa ukuba isiseko sifikelela kwinqanaba le-C25 nangaphezulu, sithe tyaba kwaye somile, asinathuli, kwaye asiphindi sihlambe. Ukuba kukho iinyosi, iindawo ezirhabaxa, imifantu, njl.njl., sebenzisa izixhobo zokulungisa ukulungisa nokulinganisa ukuqinisekisa ukuqina.
- 2. Ukusetyenziswa kwe-polyurea primer: Faka i-polyurea special primer ngokulinganayo kwisiseko ukuze uvale ii-capillary pores kumphezulu, uphucule isakhiwo somhlaba, unciphise iziphene kwi-coating emva kokutshiza, kwaye wonyuse ukunamathelana phakathi kwe-polyurea putty kunye nesamente, umgangatho wekhonkrithi. Linda ide inyangeke ngokupheleleyo ngaphambi kokuba uqhubekele kwinqanaba elilandelayo lokwakha. Ukuba kukho indawo enkulu yokuvezwa okumhlophe emva kokusetyenziswa, kufuneka iphindwe ifakelwe de umgangatho wonke ubonakale umdaka omnyama.
- 3. Ukusetyenziswa kwe-Polyurea putty: Faka i-polyurea special putty efanayo ngokulinganayo kwisiseko ukuze unyuse umgangatho ube tyaba, uvale ii-capillary pores ezingabonakaliyo emehlweni, kwaye uphephe imeko apho ukutshiza kwe-polyurea kubangela imingxunya ye-pinholes ngenxa yee-capillary pores ezisemgangathweni. Linda ide inyangeke ngokupheleleyo ngaphambi kokuba uqhubekele kwinqanaba elilandelayo lokwakha.
- 4. Ukusetyenziswa kwe-polyurea primer: Kwi-polyurea putty ecociweyo, faka i-polyurea primer ngokulinganayo ukuze unyuse ukunamathelana phakathi komaleko we-polyurea otshiziweyo kunye ne-polyurea putty.
- 5. Ulwakhiwo lwe-spray polyurea: Kwiiyure ezingama-24 emva kokuba i-primer icolile, sebenzisa izixhobo zobungcali zokutshiza ukuze utshize i-polyurea ngokulinganayo. Umphezulu wengubo kufuneka ube mpuluswa, ungaphumi, ungabi nazingxobo, amaqamza, okanye ukuqhekeka; xa kukho umonakalo okanye iingxobo ze-pin, ukulungiswa kwe-polyurea ngesandla kungasetyenziswa.
- 6. Ukusetyenziswa kwe-polyurea topcoat: Emva kokuba umphezulu we-polyurea womile, faka i-polyurea topcoat ukuthintela ukuguga, ukutshintsha kombala, kunye nokuphucula ukumelana nokuguguleka kwe-polyurea coating, ukhusela i-polyurea coating.
Izixhobo zokumba
- 1. I-substrate yesinyithi, ukuqhumisa isanti ukususa umhlwa kufikelela kwizinga le-SA2.5. Umphezulu awunalo uthuli longcoliseko, amabala eoyile, njl. Unyango olwahlukeneyo lwenziwa ngokwesiseko.
- 2. Ukutshiza nge-primer (ukuphucula ukunamathela kwe-polyurea kwisiseko).
- 3. Ulwakhiwo lokutshiza nge-polyurea (umaleko oyintloko okhuselayo osebenzayo. Ubukhulu ngokubanzi bucetyiswa ukuba bube phakathi kwe-2mm kunye ne-5mm. Izicwangciso zokwakha ezithile zibonelelwa ngokweemveliso ezifanelekileyo).
- 4. Ukwakhiwa kwe-topcoat brush/spray (ukuchasana nombala otyheli, ukumelana ne-UV, ukwandisa iimfuno ezahlukeneyo zemibala).
