Isikhumba sokwenziwa siwuhlobo lomkhiqizo wepulasitiki, obukeka futhi uzwakala njengesikhumba futhi ungashintshwa.Ngokuvamile kusekelwe endwangu, ehlanganiswe ne-synthetic resin kanye namapulasitiki ahlukahlukene.Isikhumba sokwenziwa se-PVC, isikhumba sokwenziwa se-PU.
Ngokuvamile, ngokusekelwe kwendwangu, umkhiqizo utholakala ngokugqoka noma ukumboza ungqimba lwengxube ye-resin kuwo, bese ukufudumala, ukufakwa kweplastiki, ukugoqa noma ukufaka i-embossing.Ifana nesikhumba semvelo, ithambile futhi ayigugi.Ngokusho kohlobo lwesembozo, kunezicathulo, izikhwama, njll.
E-China, abantu bajwayele ukuyisebenzisa.Inguquko eyenziwe nge-PVC resin ibizwa nge-PVC yesikhumba sokwenziwa (ngemuva kwalokhu okubizwa ngokuthi isikhumba sokwenziwa);sebenzisa;Inguquko yokwenziwa eyenziwe nge-PU resin ibizwa nge-PU artificial leather (PU leather for short): inguquko eyenziwe nge-PU resin nendwangu engalukiwe ibizwa ngokuthi yi-PU synthetic leather (isikhumba sokwenziwa ngamafuphi).
Eminyakeni yamuva nje, isikhungo semboni yesikhumba sokwenziwa emhlabeni wonke siye sadluliselwa kancane kancane eChina, esikhuthaze ukuthuthuka okusheshayo kwemboni yesikhumba yokwenziwa yaseChina kanye nemboni yesikhumba yokwenziwa.Eminyakeni emibili ezayo, isidingo esisha semboni yesikhumba sokwenziwa kanye ne-synthetic lesikhumba sizovela ikakhulukazi emakethe yasekhaya, futhi izinga lokukhula kwesidingo semboni esezansi nomfula lizoba cishe i-15%.Phakathi kwesikhumba sokwenziwa kanye nesikhumba sokwenziwa, isikhumba sezicathulo, isikhumba sefenisha kanye nesikhumba sangaphakathi semoto kuzoba izinkambu eziyinhloko, nezimpahla zezemidlalo Imishini yezempi kanye nezinto ezikhethekile kanye nezinye izinkambu ezisafufusa.
Eminyakeni yamuva nje, isikhungo semboni yesikhumba sokwenziwa emhlabeni wonke siye sadluliselwa kancane kancane eChina, esikhuthaze ukuthuthuka okusheshayo kwemboni yesikhumba yokwenziwa yaseChina kanye nemboni yesikhumba yokwenziwa.Eminyakeni emibili ezayo, isidingo esisha semboni yesikhumba yokwenziwa kanye neyokwenziwa sizovela ikakhulukazi emakethe yasekhaya, futhi ukukhula kwesidingo semboni esezansi nomfula kuzoba cishe ngo-15%, okuyisikhumba sezicathulo, isikhumba sefenisha kanye nesikhumba sangaphakathi sezimoto. kuzoba yizinkambu eziyinhloko, futhi izinkundla ezisafufusa njengezimpahla zezemidlalo, imishini yezempi kanye nezinto ezikhethekile zizovela.
Ngokombono wezinkambu zesicelo esingezansi, isikhumba sezicathulo, isikhumba sengubo, isikhumba sefenisha nesikhumba semithwalo kuzoba yizinkambu ezine eziphezulu zokufakwa kwe-substrate yesikhumba e-China ngo-2020. Phakathi kwazo, isikhumba sezicathulo yinkambu yesicelo enomthamo omkhulu wokuthengisa wesikhumba. indwangu eyisisekelo e-China, efinyelela kumathani angama-509000, ibalwa ku-36.86%;Kulandelwa yisikhumba sezingubo, isikhumba sefenisha nesikhumba semithwalo, okubalelwa ku-17.60%, 17.45% no-14.99% ngokulandelana.
Kuze kube manje, cishe kunabakhiqizi abakhulu besikhumba sokwenziwa abangama-549 eChina.Inani eliphelele labakhiqizi abahlanu abaphezulu kulayini wokukhiqiza libalelwa ku-6% wawo wonke umthamo.Imakethe yesikhumba sokwenziwa ayiphezulu.Amabhizinisi asembonini ngokuyisisekelo alandela isimiso semakethe, athembele kubuchwepheshe, umkhiqizo, isikali, njll. ukuze aqhudelane ngokugcwele emakethe, futhi imboni inezinga eliphezulu lokumaketha.
Ithrendi Yokuthuthukiswa Kwesikhumba Sokwenziwa
Eminyakeni yamuva nje, ukuncintisana embonini yasekhaya ye-PU yesikhumba yokwenziwa kuye kwadlondlobala, futhi imboni ibhekene noshintsho noshintsho ngenxa yokwanda kwengcindezi ekhuphukayo yomnotho wasekhaya, isidingo esintengayo somfula, kanye nezidingo eziqinile zokuphepha, ukuvikelwa kwemvelo kanye nomsebenzi. impilo.Imboni isingene esigabeni sokulungiswa okujulile, ngokuhlukaniswa okusobala kanye nokugxila embonini okwengeziwe.Kusukela ngo-2016, ukugadwa kokuvikelwa kwemvelo kanye nokuhlolwa kokuphepha kubeke phambili izidingo eziphakeme zokukhiqiza okuphephile kanye nokukhiqizwa okuluhlaza kwamabhizinisi.Imakethe ingene esigabeni somnqobi ithatha konke futhi onamandla uhlala eqinile.Ngenxa yalokhu, abahlinzeki bempahla eluhlaza ekhuphuka nomfula (amabhizinisi amakhulu asekhaya nakwamanye amazwe nabakhiqizi bezinto ezifana nendwangu eyisisekelo) kancane kancane bathuthela endaweni eyodwa, futhi bazonikezwa amandla amakhulu entengo.Isimo esingokwemvelo samandla entengo aqinile wabahlinzeki abakhuphuka nomfula siphinde sibeke umkhawulo endaweni yenzuzo yamabhizinisi.Isikhumba se-PVC sidinga i-plasticizer DOP nezinsimbi eziqinile ezifana nomthofu ne-cadmium, okulula ukungcolisa imvelo.Ifakwe kuhlu njengephrojekthi yokuthuthukisa evimbelayo kuKhathalogi Yesiqondiso Sokuhlelwa Kabusha Kwezimboni.Kodwa-ke, ama-solvents afana ne-polyurethane ne-DMF, asetshenziswa kakhulu ekukhiqizeni isikhumba se-PU, azokhiqiza ama-volatile organic compounds (VOCs), okungafanele akhuthazwe ngamandla.Umkhuba wokuthuthukiswa okuluhlaza kanye nemvelo-friendly kwesikhumba sokwenziwa e-China kuye kwaba sobala kakhulu.
