Polyurethane spraying is high pressure polyurethane spraying equipment.Nokuti zvinhu zvehigh-pressure spray equipmentinoroverwa mukamuri diki yekusanganisa uye inorukwa zvine simba nekumhanya kukuru, kusanganisa kwakanaka kwazvo.Izvo zvinhu zvinofamba nekumhanya zvakanyanya zvinogadzira madonhwe mhute pamuromo wespray gunuye woapfapfaidza zvakaenzana pamusoro pechinhu chacho.Foamed polyurethane spraying inonyanya kushandiswa kuchengetedza kupisa uye kuvhara mukuchengetedza kupisa uye firiji.Inoshandiswa kupfekedza zvinhu zvinopisa zvekudzivirira zvakadai sematangi akakura ekuchengetera matangi, hombe-diameter yakakosha-yakavezwa pombi fittings, uye madziro ekuchengetedza anotonhora, uye inogona kuona pa-saiti kupupa.
Matambudziko mazhinji anowanzosangana mukuvakwa kwepolyurethane spraying, saka ndeapi matambudziko aya?Izvi zvakaitika sei?
Iyi inonyanya inyaya yekuita, iyo inotsanangurwa sezvizvi:
| CommonPdambudziko | Reason | Suggest |
| Yakakasharara uye isina kurongeka furo pamusoro | Yakashata atomization, kunyanya yakajairika neyemhuri air-mixing sprayers | Iyo yekumashure dzvinyiriro yemhepo compressor uye chinhambwe kubva pachigadziko cheplate chinogona kugadziriswa zvakakodzera.Kana zvichibvira, kurebesa uye kuderedza mhepo inosanganisa nozzle.Small bore.Iyo polyurethane high-pressure sprayer inogona kuchengetedzwa zvakanaka kure ne substrate. |
| Furo nguva yakakurumidza uye viscosity yevatema nechena | ||
| Furo rakapfava zvakanyanya | Polyether yakawandisa | Zvinokurudzirwa kuita iyo yemahara furo bvunzo pachiyero chakakodzera.Kana ichiri nyoro, unogona kuwedzera chikamu cheisocyanatel zvakakodzera.Kana ichiri kupfava, inofanira kuongororwa kana ethylenediamine inofanira kushandiswa, zvakakodzera kuwedzera zvinhu zvakasvibirira zvinoshandiswa mumucheka muchena. |

| Mvura yakawandisa muhurongwa | Kana chete pasi paine brittle, funga kana mutsauko uripo pakati petembiricha yezvinhu uye tembiricha yepakati wakakurisa, kana tembiricha yezvinhu yakakwira, uye tembiricha yepakati yakadzikira.Chimwe chikonzero ndechekuti kune misiyano yakawandisa muviscosity pakati pepolyether neIsocyanate nezvimweisocyanate. |

| Yakaderera peel simba pakati pefuro uye substrate | Pamusoro pe substrate haina kuchena, ine guruva rinoyangarara kana mafuta mavara | Ikoko kwakanga kusina kupinda kwe substrate, uye unyoro pamusangano waionekwa nekuputika.Uye zvakare, tembiricha ye substrate yakadzikira, uye kukurumidza kupupa kwakakurumidza.“Kupfapfaidza” (kureva kupfapfaidza nzvimbo yakatetepa nekukasira), asi pfapfaidzo yakakora inogonawo kukonzera kukandirana nekusvuuka. |

| Nekuda kweiyo yakaderera dhigirii yebazi uye kushanda kweiyo polyether inoshandiswa mufoaming system | Sucrose, mannitol inogona kuwedzerwa se polyether starter sezvakakodzera.Pamusoro pezvo, wedzera zvakakodzera huwandu hwematanho ekupfapfaidza panguva yekuvaka kudzivirira kudzokororwa zviitiko |

| Nguva yekupupa inokurumidza kana kuti inononoka | Chenjerera kudzora kumhanya kwefuro |
| Yakawandisa silicone oiri surfactant inowedzerwa kune iyo foaming system |
