Ezikhathini zamuva, izinto eziningi ezintsha ziye zavela, ukuze izinto ezinezindleko eziphakeme esikhathini esidlule ziye zashintsha kancane kancane ngentengo, ikakhulukazi ezicathulweni namapayipi.

Yiqiniso, ezinye izinto zibonakala zisesimweni esihle. Ngemva kophenyo, ungakwazi ukuqonda ukuthi yiziphi ezinye izici.

Isibonelo, izinto ezimbili ze-pvc ne-pu, abantu abaningi bebelokhu benokungabaza, ngakho-ke umehluko phakathi kwezinto ze-pvc ne-pu?

Umehluko phakathi kwezinto ze-pvc ne-pu

Isikhumba se-PU siyinkimbinkimbi kakhulu kunesikhumba se-PVC ekukhiqizeni inqubo. Ngoba indwangu yesisekelo se-PU iyindwangu ye-PU ye-canvas enamandla aqinile, ngaphezu kokumbozwa kwendwangu ephezulu, indwangu yesisekelo nayo ingafakwa phakathi ukuze iyenze Ukubukeka akukwazi ukubona ubukhona bendwangu.

1. Izinto ezibonakalayo zesikhumba se-PU zingcono kunesikhumba se-PVC, zimelana ne-tortuosity, ukuthamba, amandla aqinile aphezulu, futhi ziphefumula (ayikho i-PVC).

Iphethini yesikhumba se-PVC yakhiwa ngokucindezela okushisayo kwama-roller ephethini ensimbi. Iphethini yesikhumba se-PU iyashisa icindezelwe ebusweni besikhumba esiqediwe kancane ngohlobo lwephepha lephethini. Ngemuva kokulinda ukupholisa, isikhumba sephepha siyahlukaniswa futhi siphathwe phezulu.

Intengo ye-PU ingaphezu kokuphindwe kabili kwe-PVC, futhi intengo yesikhumba se-PU enezidingo ezithile ezikhethekile iphakeme ngokuphindwe izikhathi ezingu-2-3 kunaleyo yesikhumba se-PVC.

Ngokuvamile, iphepha lephethini elidingekayo lesikhumba se-PU lingalahlwa kuphela ngemva kwezikhathi ezingu-4-5. Isikhathi sokusebenzisa i-roller yephethini side, ngakho-ke izindleko zesikhumba se-PU ziphakeme kunezesikhumba se-PVC.

2. Indlela yokuhlukanisa i-PU ne-PVC ilula kakhulu.

Kusuka emakhoneni, isisekelo sendwangu ye-PU sikhulu kakhulu kune-PVC. Kukhona nomehluko emuzweni. Umuzwa we-PU uthambile. I-PVC izwakala ilukhuni.

Ungasebenzisa futhi umlilo ukushisa, ukunambitheka kwe-PU kulula kakhulu kune-PVC.
