Ijazi lemvula le-TPU

I-TPU inamandla amakhulu okudonseka, amandla aphezulu okudonseka, ukuqina kanye nezakhiwo zokulwa nokuguga, futhi iyinto yokuvikela imvelo evuthiwe. Okusho ukuthi, i-TPU raincoat uhlobo lwe-raincoat oluthandwa umphakathi kulezi zinsuku. Ukumelana nokubanda okuvelele: I-TPU inezinga lokushisa eliphansi lokushintsha kwengilazi, igcina ukunwebeka okuhle, ukuguquguquka kanye nezinye izakhiwo zomzimba ku--35 degrees Celsius.

Isingeniso

I-TPU isifinyezo se-Thermoplastic Urethane, esibizwa ngokuthi i-thermoplastic polyurethane elastomer ngesiShayina. I-TPU iyinto eyenziwe nge-polymer eyenziwe ngama-molecule e-diisocyanate njenge-diphenylmethane diisocyanate (MDI) noma i-toluene diisocyanate (TDI) kanye ne-polyol enkulu kanye ne-polyol ephansi ye-molecule (i-chain extender), ezihlanganiswa ndawonye ngendlela yokusabela.

I-TPU inamandla amakhulu okudonseka, amandla aphezulu okudonseka, ukuqina kanye nokumelana nokuguga, futhi iyinto yokuvikela imvelo evuthiwe. Okusho ukuthi, ijazi lemvula le-TPU uhlobo lwejazi lemvula oluthandwa umphakathi namuhla.

Izizathu zokukhetha izinto ze-TPU

Ijazi lemvula le-TPU uhlobo olusha lwejazi lemvula elivikela imvelo, futhi imodeli yokusetshenziswa ihilela insimu yobuchwepheshe yemikhiqizo yejazi lemvula. Okokuqala, izinto zejazi lemvula zenziwe ngezinto ezibola ngokuphelele, ukuze kugwenywe ukungcoliswa kwemvelo ngemva kokuba lilahliwe. Uma ijazi lemvula lingasetshenziswa futhi lidinga ukulahlwa, lingangcwatshwa enhlabathini. Ngemva kwesikhathi esithile, izinto zejazi lemvula zizobola ngokuphelele, futhi imbewu ingahluma futhi ikhule enhlabathini ukuze yakhe izitshalo, okungaxazululi nje inkinga yokuvikela imvelo yejazi lemvula, kodwa futhi okunomthelela wokutshala izihlahla kanye nokufaka uhlaza.
