Gutera polyurethane ni umuvuduko mwinshi ibikoresho byo gutera polyurethane.Kuberako ibikoresho byaibikoresho byo gutera umuvuduko mwinshiisunitswe mucyumba gito cyo kuvanga no kuzunguruka cyane kumuvuduko mwinshi, kuvanga nibyiza cyane.Ibikoresho bigenda kumuvuduko mwinshi bikora neza ibitonyanga byiza kuri nozzle yagutera imbundahanyuma uyisasa neza hejuru yikintu.Gutera polyurethane ifuro ikoreshwa cyane cyane mukubungabunga ubushyuhe no gufunga mukubika ubushyuhe no gukonjesha.Ikoreshwa mugutwikira ibikoresho byubushyuhe bwumuriro nkibigega binini byo kubika ibintu, ububiko bunini bwa diametre idasanzwe ifite imiyoboro, hamwe ninkuta zububiko bukonje, kandi irashobora gutahura aho ifuro.
Ibibazo byinshi bikunze guhura nabyo mukubaka polyurethane gutera, none nibihe bibazo?Ibyo byagenze bite?
Iki nikibazo ahanini cyimikorere, isobanurwa gutya:
| CommonProblem | Reason | Tanga igitekerezo |
| Ubuso bubi kandi budasanzwe | Atomisiyasi mbi, cyane cyane ikunze kuvangwa murugo | Umuvuduko winyuma wa compressor yumuyaga nintera iri hagati yicyapa fatizo irashobora guhinduka muburyo bukwiye.Niba bishoboka, ongera kandi ugabanye umwuka uvanga nozzle.Bore nto.Polyurethane itera umuvuduko mwinshi irashobora kubikwa neza kure ya substrate. |
| Igihe cyo kubira igihe cyihuse kandi cyijimye cyumukara n'umweru | ||
| Ifuro iroroshye cyane | Byinshi cyane | Birasabwa gukora ikizamini cyubusa kubusa.Niba bikiri byoroshye, urashobora kongera igipimo cyaisocyanatel bikwiye.Niba bikiri byoroshye, bigomba kugenzurwa niba Ethylenediamine igomba gukoreshwa, byongera neza ibikoresho fatizo bikoreshwa mubikoresho byera. |
| ifuro ni crisp
| Amazi menshi muri sisitemu | Niba gusa ubuso bworoshye, tekereza niba itandukaniro riri hagati yubushyuhe bwibintu nubushyuhe bwibidukikije ari binini cyane, niba ubushyuhe bwibintu buri hejuru, nubushyuhe bwibidukikije buri hasi.Indi mpamvu nuko hariho itandukaniro ryinshi mubucucike hagati ya polyether na Isocyanate nibindi byinshiisocyanate. |
| Itandukaniro rya viscosity hagati ya polyethernaIsocyanateni binini cyane | ||
| Imbaraga nke zishishwa hagati ya furo na substrate | Ubuso bwa substrate ntabwo busukuye, hamwe n'umukungugu ureremba cyangwa amavuta | Nta gucengera kwa substrate, kandi ubushuhe kuri interineti bwagaragaraga no gukuramo.Mubyongeyeho, ubushyuhe bwa substrate buri hasi cyane, kandi umuvuduko wo kubira urihuta cyane."Gutera" (ni ukuvuga gutera urwego ruto rwihuse), ariko spray nini irashobora gutera impagarara nyinshi no gukuramo. |
| bubble
| Bitewe nurwego rwo hasi rwishami nimikorere ya polyether ikoreshwa muri sisitemu yo kubira | Sucrose, mannitol irashobora kongerwamo nka polyether itangira nkuko bikwiye.Byongeye kandi, ongera bikwiye umubare wibiti bya spray mugihe cyo kubaka kugirango wirinde ibintu byinshi |
| gutandukana
| Igihe cyo kubira kirihuta cyane cyangwa gitinda cyane | Witondere kugenzura umuvuduko |
| Amavuta ya silicone menshi cyane yongewe kuri sisitemu yo kubira ifuro |
