I-PU FOAM ithatha isikhathi esingakanani ukwelapha ngemva kokufaka isicelo?

I-PU FOAM, okuya kuyo ukuze ivalwe futhi igcwaliswe, idume ngokuguquguquka kwayo - kodwa ukwazi umugqa wesikhathi wayo wokwelapha kanye nokubamba amagwebu ngokweqile kuwukhiye wephrojekthi ebushelelezi.

Imvamisa, i-PU FOAM iqala ukugqama emizuzwini eyi-10 - 20 ngemuva kokufakwa, okusho ukuthi ubuso buqina ngokwanele ukuthi bungathintwa. Ukuyelapha ngokugcwele (uma isiqine ngokuphelele futhi isilungele ezinye izinyathelo) kuthatha amahora angama-24 – 48. Lokhu kuyehluka, nokho: izimo ezifudumele, ezomile ziyasheshisa ukuphulukiswa, kuyilapho izindawo ezibandayo nezinomswakama zinganweba kuze kufike emahoreni angama-72. Ngaso sonke isikhathi hlola ilebula yomkhiqizo - amanye amafomula okwelapha ngokushesha anciphisa isikhathi sokwelapha esigcwele sibe amahora angu-12.

Uma seselaphekile ngokuphelele, igwebu elidlulele alikwazi ukusulwa , ngakho uzodinga amathuluzi . Okokuqala, sebenzisa ummese womsebenzi obukhali noma isisiki segwebu ukuze usike inqwaba yokudlulela, ulandele umkhonto ongaphezulu ukuze ugweme ukulimaza isisekelo. Kumabhithi amancane, asele, i-fine-grit sandpaper (120 - 180 grit) isebenza ukushelela indawo. Uma igwebu lisendaweni ependekayo, sebenzisa isihlabathi esincane kuze kube kusihlwa, bese uhlanza ngendwangu eyomile ngaphambi kokudweba noma ukuvala.

Khumbula: ungalinge usebenzise amanzi ukususa igwebu elilashiwe - ngeke kusebenze . Namathela ekusikeni nasekusandeni, futhi uzothola isiphetho esihle, esichwepheshile!
