Isikhumba sokwenziwa luhlobo lwemveliso yeplastiki, ekhangeleka kwaye ivakalelwa njengesikhumba kwaye inokutshintshwa.Ngokuqhelekileyo isekelwe kwilaphu, ifakwe nge-resin yokwenziwa kunye neeplastiki ezahlukeneyo.I-PVC yesikhumba eyenziweyo, i-PU yesikhumba sokwenziwa.
Ngokuqhelekileyo, ngokusekelwe kwindwangu, imveliso ifunyenwe ngokugubungela okanye ukugubungela umxube we-resin umxube kuyo, emva koko ukufudumeza, iplastiki, i-rolling okanye i-embossing.Ngokufana nesikhumba sendalo, sithambile kwaye sinxiba-resistant.Ngokohlobo lwesigqubuthelo, kukho izicathulo, iingxowa, njl.
ETshayina, abantu baqhele ukuyisebenzisa.I-revolution eyenziwe nge-PVC ye-resin ibizwa ngokuba yi-PVC yesikhumba eyenziweyo (emva koku kubhekiselwa kuyo njengesikhumba sokwenziwa);sebenzisaUguqulo olwenziweyo olwenziwe nge-PU resin lubizwa ngokuba yi-PU yesikhumba eyenziweyo (isikhumba sePU ngokufutshane): uguqulo olwenziweyo olwenziwe nge-PU resin kunye nelaphu elingalukwanga libizwa ngokuba yi-PU yesikhumba yokwenziwa (isikhumba sokwenziwa ngokufutshane).
Kwiminyaka yakutshanje, iziko lehlabathi elenziwe ngethwathwa kunye neziko lokwenziwa kwesikhumba liye latshintshela eTshayina, nto leyo ekhuthaze uphuhliso olukhawulezayo lweshishini lesikhumba lokwenziwa laseTshayina kunye nelenziweyo.Kwiminyaka emibini ezayo, imfuno entsha yesikhumba sokwenziwa kunye nemveliso yesikhumba sokwenziwa iya kuvela ikakhulu kwimarike yasekhaya, kwaye izinga lokukhula kwemfuno yoshishino olusezantsi luya kuba malunga ne-15%.Phakathi kwesikhumba sokwenziwa kunye nesikhumba sokwenziwa, izihlangu zesikhumba, ifenitshala yefenitshala kunye nesikhumba sangaphakathi semoto iya kuba yimimandla ephambili, kunye nempahla yezemidlalo Izixhobo zomkhosi kunye nezixhobo ezizodwa kunye nezinye iindawo ezivelayo.
Kwiminyaka yakutshanje, iziko lehlabathi elenziwe ngethwathwa kunye neziko lokwenziwa kwesikhumba liye latshintshela eTshayina, nto leyo ekhuthaze uphuhliso olukhawulezayo lweshishini lesikhumba lokwenziwa laseTshayina kunye nelenziweyo.Kule minyaka mibini izayo, imfuno entsha yoshishino lwesikhumba eyenziweyo kunye nemveliso yesikhumba eyenziweyo iya kuvela ikakhulu kwimarike yasekhaya, kwaye ukukhula kwemfuno yoshishino olusezantsi kuya kuba malunga ne-15%, apho isikhumba sezihlangu, isikhumba sefenitshala kunye nesikhumba sangaphakathi semoto. iya kuba yimimandla ephambili, kunye neendawo ezivelayo ezifana nempahla yezemidlalo, izixhobo zomkhosi kunye nezixhobo ezizodwa ziya kuvela.
Ngokombono weendawo ezisezantsi zesicelo, isikhumba sezihlangu, isikhumba sempahla, ifanitshala yesikhumba kunye nesikhumba sempahla iya kuba yimimandla emine ephezulu yesicelo se-substrate e-China ngo-2020. ilaphu lesiseko eTshayina, ukuya kuthi ga kwi-509000 yeetoni, ezibalelwa kwi-36.86%;Ilandelwa luthwathwa lwempahla, ufele lwefanitshala kunye nofele lwemithwalo, kubalelwa kwi-17.60%, 17.45% kunye ne-14.99% ngokulandelelanayo.
Ukuza kuthi ga ngoku, kukho malunga nama-549 abenzi abakhulu besikhumba sokwenziwa eTshayina.Umthamo opheleleyo wabavelisi abahlanu abaphezulu kumgca wemveliso wenza malunga ne-6% yomthamo opheleleyo.Ukuxinwa kweemarike zesikhumba sokwenziwa akukho phezulu.Amashishini kushishino ngokusisiseko alandela umgaqo wemarike, athembele kwitekhnoloji, uphawu, isikali, njl.njl. ukukhuphisana ngokupheleleyo kwimarike, kwaye ishishini linenqanaba eliphezulu lokuthengisa.
Uphuhliso Trend of Synthetic Leather
Kwiminyaka yakutshanje, ukhuphiswano kwishishini lesikhumba le-PU lasekhaya liye laqina, kwaye ishishini lijongene nohlengahlengiso kunye notshintsho ngenxa yokunyuka koxinzelelo loqoqosho lwasekhaya, imfuno ephantsi yomlambo, kunye neemfuno ezingqongqo zokhuseleko, ukhuseleko lokusingqongileyo kunye nomsebenzi. impilo.Ishishini lingene kwinqanaba lohlengahlengiso olunzulu, kunye nepolarization ebonakalayo kunye nokwanda koxinzelelo lweshishini.Ukusukela ngo-2016, ukulawulwa kokusingqongileyo kunye nokuhlolwa kokhuseleko kuye kwabeka phambili iimfuno eziphakamileyo zemveliso ekhuselekileyo kunye nemveliso eluhlaza yamashishini.Imarike ingene kwinqanaba lokuphumelela lithatha yonke into kwaye inamandla ihlala yomelele.Kangangokuba, ababoneleli ngemathiriyeli ekrwada abanyukayo (amashishini amakhulu ekhemikhali asekhaya nakwamanye amazwe kunye nabavelisi bemathiriyeli efana nelaphu elisisiseko) ngokuthe ngcembe baya kulawulo lwemonopoly, kwaye baya kunikwa amandla amakhulu exabiso.Imeko yendalo yamandla amaxabiso anamandla ababoneleli abanyukayo bayayinciphisa ngakumbi indawo yenzuzo yamashishini.Isikhumba sePVC sidinga i-plasticizer DOP kunye nezizinzisi ezinesinyithi esinzima njengelothe kunye ne-cadmium, ekulula ukungcolisa okusingqongileyo.Idweliswe njengeprojekthi yophuhliso oluthintelweyo kwiKhathalogu yesiKhokelo soHlengahlengiso lwezoShishino.Nangona kunjalo, i-solvents efana ne-polyurethane kunye ne-DMF, esetyenziswa ngokubanzi kwimveliso ye-PU yesikhumba, iya kuvelisa i-volatile organic compounds (VOCs), engafanele ikhuthazwe ngamandla.Umkhwa wokuphuhliswa kohlaza kunye nokusingqongileyo kwesikhumba sokwenziwa e-China kuye kwacaca kakhulu.
