Iyini isikhumba se-PU? Kufanele sihlukanise kanjani isikhumba se-PU nesikhumba sangempela?

.Isikhumba se-PU siyinto yokwenziwa eyenziwe ngumuntu. Isikhumba sokwenziwa esivamise ukuba nokubukeka nokuzwakala okwesikhumba sangempela, kodwa sishibhile, asihlali isikhathi eside, futhi singaqukatha amakhemikhali. .
Isikhumba se-PU akusona isikhumba sangempela. Isikhumba se-PU wuhlobo lwesikhumba sokwenziwa. Yenziwe ngezinto ze-fiber zamakhemikhali, kuyilapho isikhumba sangempela senziwe futhi sicutshungulwe ngesikhumba sesilwane. Isikhumba sangempela esishiwo emakethe ngokuvamile ungqimba lokuqala lwesikhumba kanye nolwesibili lwesikhumba.
Isikhumba se-PU, igama laso eligcwele okuyisikhumba se-polyurethane, siwumsebenzi wokwenziwa owenziwe ngokufaka i-synthetic polymer coating ebusweni bemicu yezilwane. Lezi ezinengilazi ngokuvamile zihlanganisa polyurethane. Isikhumba se-PU sinokumelana okuhle kakhulu kokugqoka, ukuphefumula, ukumelana nokuguga kanye nokuguquguquka. Umthelela wokubukeka ufana kakhulu nesikhumba sangempela, futhi ungcono kakhulu kunesikhumba semvelo kwezinye izakhiwo ezibonakalayo. Kodwa-ke, uma kuqhathaniswa nesikhumba sangempela, isikhumba se-PU sinokuhlukahluka kokuqina, ukugcinwa nokuvikelwa kwemvelo.
Senziwa kanjani isikhumba se-PU? Igama eliphelele le-PU lesikhumba yi-polyurethane leather. Yenziwa ngokufaka i-polyurethane resin engutsheni noma kwendwangu engalukiwe, bese ingena ezinqubweni ezifana nokushisisa nokugqamisa ukuze ibe nemibala ehlukene, ukwakheka kanye nogqinsi. Isikhumba se-PU singalingisa ukubukeka nokuzwakala kwezikhumba zangempela ezihlukahlukene, njengesikhumba senkomo, isikhumba semvu, ingulube, njll.

Yiziphi izinzuzo ze-PU lesikhumba? Okokuqala, isikhumba se-PU silula futhi ngeke sithwalise izinyawo. Okwesibili, isikhumba se-PU simelana kakhulu nokugqokwa futhi akulula ukuklwejwa noma ukulinyazwa. Okwesithathu, isikhumba se-PU kulula ukusihlanza, vele usisule ngendwangu emanzi. Okokugcina, isikhumba se-PU sinobungani bemvelo futhi ngeke sibangele ukulimala noma ukungcola ezilwaneni.

Ngakho-ke, yiziphi izingqinamba ze-PU lesikhumba? Okokuqala, isikhumba se-PU asiphefumuli, okwenza izinyawo zijuluke noma zinuke kalula. Okwesibili, isikhumba se-PU asimelani namazinga okushisa aphezulu futhi sithambekele ekugugeni noma ekugugeni. Okwesithathu, isikhumba se-PU asithambile futhi sikhululekile ngokwanele, futhi asinakho ukunwebeka nokulingana kwesikhumba sangempela. Okokugcina, isikhumba se-PU asinaso isiphetho esiphezulu futhi esishisayo ngokwanele, futhi asinakho ukucwebezela nokuthungwa kwesikhumba sangempela.
Izindlela zokuhlukanisa isikhumba se-PU nesikhumba sangempela zifaka:

Umthombo nezithako: Isikhumba sangempela siphuma esikhumbeni sesilwane, futhi ngemva kokushukwa nezinye izinqubo, sinokwakheka nokuthinta kwemvelo okuyingqayizivele. Isikhumba se-PU siyisikhumba sokwenziwa, sine-polyurethane resin njengengxenye eyinhloko, eyenziwe ukusabela kwamakhemikhali, ukumelana nokugqokwa okuhle, ukumelana ne-crease kanye nokumelana nokuguga.
Ukubukeka nokuthinta: Isikhumba sangempela sinikeza ukuthinta kwemvelo nokwangempela ngokuthungwa kwemvelo okuyingqayizivele. Yize isikhumba se-PU singakwazi ukulingisa ukuthungwa nokuthinta kwesikhumba sangempela, sisabukeka njengokwenziwa jikelele. Isikhumba sangempela sinemigqa ecace kakhulu, futhi ucezu ngalunye luhlukile. Imigqa yesikhumba se-PU ifiphale kakhulu futhi iyanyamalala. Isikhumba sangempela sizwakala sithambile futhi sinwebeka, sithambile futhi sibushelelezi. Isikhumba se-PU sizwakala sibuthaka futhi sine-astringent kancane.

Ukuqina: Isikhumba sangempela ngokuvamile sihlala isikhathi eside, sinokuqina okuphezulu nokunwebeka, futhi singamelana nomthelela wangaphandle nokungqubuzana. Nakuba isikhumba se-PU sinokumelana okuhle kokugqoka, singase sibe nokuguga, ukuqhekeka nezinye izinkinga ngemva kokusetshenziswa isikhathi eside.
Ukunakekelwa nokunakekelwa: Isikhumba sangempela sidinga ukunakekelwa nokunakekelwa njalo, futhi ama-ejenti okunakekelwa kwesikhumba asetshenziselwa ukuhlanza, ukuthambisa kanye nokuvimbela amanzi. Isikhumba se-PU kulula ukusinakekela, vele usisule ngendwangu emanzi.
Ukuvikela imvelo: Isikhumba sangempela siphuma esikhumbeni sesilwane, futhi kukhona udoti kanye nokungcola okumbalwa ekukhiqizeni kwaso. Njengesikhumba sokwenziwa, isikhumba se-PU singadala ukungcoliswa okuthile kwemvelo ohlelweni lwaso lokukhiqiza.
Mayelana nephunga: Isikhumba sangempela sinephunga elivamile lesikhumba, futhi siba nephunga elimnandi njengoba isikhathi sihamba. Isikhumba se-PU sizoba nephunga lepulasitiki eliqinile. Isikhumba sangempela sizoshwabana futhi sinuke njengezinwele ezivuthayo lapho sihlangana namalangabi. Isikhumba se-PU sizoncibilika futhi sinuke njengopulasitiki ovuthayo lapho sihlangana namalangabi.
Ukusebenza kwezikhathi ezahlukene

Ukugqokwa kwansuku zonke: Ngemikhiqizo yesikhumba yokugqoka nsuku zonke, njengezicathulo nezikhwama zezandla, abathengi bangakhetha ngokuvumelana nezidingo zabo kanye nesabelomali. Uma uphishekela ukunethezeka nokuphefumula, isikhumba sangempela siyisinqumo esingcono; uma unaka kakhulu intengo nokuhlukahluka kokubukeka, isikhumba se-PU sibuye sibe yisinqumo esihle.

Izikhathi ezikhethekile: Kwezinye izikhathi ezikhethekile, njengemihlangano yebhizinisi, idina elisemthethweni, njll., imikhiqizo yesikhumba sangempela ivamise ukubonisa ubuhle kanye nesimo esihloniphekile. Kwezinye izikhathi ezijwayelekile, njengemidlalo yangaphandle, ukuhamba, njll., imikhiqizo yesikhumba ye-PU ithandwa ngenxa yokukhanya nokuqina kwayo.
Kafushane, isikhumba se-PU nesikhumba sangempela ngasinye sinezici zabo kanye nezimo ezisebenzayo. Abathengi kufanele benze ukukhetha ngokusekelwe ezidingweni zabo kanye nesabelomali lapho bethenga.
