Embonini yokucubungula ukudla, ibhande lokuthutha aliyona nje ingxenye eyinhloko yokuhamba kwezinto, kodwa futhi liyisihluthulelo sokuqinisekisa ukuphepha kokudla nokusebenza kahle kokukhiqiza. Uma ubhekene nohlu olubanzi lwezinto zebhande lokuthutha emakethe, i-PU (i-polyurethane) ne-PVC (i-polyvinyl chloride) ngokungangabazeki yizinketho ezimbili ezivamile. Nakuba ukubukeka kokubili kufana, umehluko wokusebenza ubalulekile. Kulesi sihloko, sizohlaziya umehluko oyinhloko phakathi kwalokhu kokubili kusukela kuzici zempahla, izimo zohlelo lokusebenza, ukuphumelela kwezindleko kanye nobunye ubukhulu, ukukusiza wenze isinqumo esihlakaniphile.

 Umdlalo Wokuphepha Nokusebenza

 

Amabhande okuthutha e-PU: “izinga legolide” lokuphepha kokudla.

Isitifiketi sezinga lokudla: Amabhande okuthutha e-PUzenziwe ngezinto ze-polyurethane, ezihlangabezana nezindinganiso zamazwe ngamazwe zokuphepha kokudla njenge-FDA, ezingenabuthi futhi ezingenaphunga, futhi zingathintana ngokuqondile nokudla, ezifanele kakhulu indawo yokubhaka, i-confectionery, imikhiqizo yenyama nezinye izimo ezihlanzeke kakhulu.

I-Oil and Wear Resistant: Impahla ye-PU inokumelana nowoyela okuhle kakhulu, okungamelana nokuguguleka kwamafutha, amafutha ezilwane kanye namafutha emishini, futhi ngesikhathi esifanayo, inokumelana okuvelele kokugqoka, okulungele ukuhambisa isinkwa, inhlama nezinye izinto ezinamathela kalula.

I-Anti-cut kanye ne-anti-adhesion: ubulukhuni obukhulu (92 Shore hardness) kanye ne-coefficient ephansi yokungqubuzana, ukuze ikwazi ukumelana nokusikwa kommese futhi kungabi lula ukulimaza, nokusebenza kokulwa nokunamathela kuhle kakhulu, ukugwema izinsalela zokudla.

Ibanga elibanzi lokumelana nezinga lokushisa: izinga lokushisa lokusebenza lingafinyelela -20 ℃ kuya ku-80 ℃, livumelane nezimo ezibucayi ezifana nokugcinwa okubandayo nokubhaka.

 

Ibhande le-PVC lokuthutha: ukukhetha okungabizi kakhulu, kodwa kufanele kusetshenziswe ngokuqapha

Ezomnotho kanye nokusebenza: Ibhande le-PVC lokuthuthayenziwe ngendwangu ye-polyester fiber futhi imbozwe ngesendlalelo sokunamathisela se-PVC, izindleko zingama-60% -70% kuphela webhande lokuhambisa le-PU, elifanele amabhizinisi anesabelomali esilinganiselwe.

Ukumelana ne-Acid ne-alkali nomthwalo omncane:Inokumelana okuthile ne-asidi ebuthakathaka kanye nemvelo ye-alkali futhi ifanele ukuthuthwa komthwalo omncane wezithelo nemifino, njll. Nokho, impofu ekuphikisweni kwamafutha, futhi ukuthintana kwamafutha namafutha kuzoholela kalula ekwandiseni ungqimba lwenjoloba futhi siwe.

Umkhawulo wezinga lokushisa: izinga lokushisa elisebenzayo lisukela ku -10℃ liye ku-80℃, futhi kulula ukuba brittle futhi ufinyeze impilo yesevisi ngaphansi kwemvelo yokushisa ephezulu.

Ingozi yokuphepha kokudla:abanyeAmabhande okuthutha e-PVCingase ibe nama-plasticizers, ukuthintana ngokuqondile nokudla kunezingozi zokuphepha, udinga ukukhetha impahla ye-PVC yezinga lokudla egunyazwe yi-FDA.
