Yintoni iPU Synthetic yesikhumba

I-PU yesikhumba eyenziwe ngesikhumba se-polyurethane. Ngoku isetyenziselwa ukuhombisa imithwalo, iimpahla, izihlangu, izithuthi kunye nefenitshala. Iye yaqatshelwa ngokwandayo yimarike. Uluhlu lwayo olubanzi lwesicelo, ubuninzi obukhulu kunye neentlobo ezininzi azinelisekanga ngesikhumba sendalo yendalo. Umgangatho wesikhumba wePU ulungile okanye umbi. Isikhumba esihle sePU sibiza ngakumbi kunesikhumba, sinesiphumo esihle sokubunjwa kunye nomphezulu oqaqambileyo.

01: Iimpawu zezinto eziphathekayo kunye neempawu

I-PU yesikhumba eyenziweyo isetyenziselwa ukubuyisela i-PVC yesikhumba sokwenziwa, kwaye ixabiso layo liphezulu kune-PVC yesikhumba sokwenziwa. Ngokumalunga nokwakheka kweekhemikhali, isondele kwilaphu lesikhumba. Ayidingi i-plasticizer ukufezekisa iipropathi ezithambileyo, ngoko ayiyi kuba nzima kwaye ibe brittle. Ngelo xesha, ineenzuzo zemibala ecebileyo kunye neepatheni ezahlukeneyo, kwaye ixabiso ngokuqhelekileyo lincinci kunempahla yesikhumba, ngoko ke yamkelwa ngabathengi.

Enye yiPU yesikhumba. Ngokubanzi, icala elingasemva lesikhumba se-PU ngumaleko wesibini wethwathwa ekrwada, egqunywe ngomaleko we-PU resin, ngoko ikwabizwa ngokuba yifilim yesikhumba senkomo. Ixabiso layo liphantsi kwaye izinga lokusetyenziswa liphezulu. Ngokutshintsha kobugcisa, iye yenziwa yaziintlobo ngeentlobo zamabanga ahlukeneyo, afana nesikhumba esiphuma kumazwe angaphandle esinemigangatho emibini. Ngenxa yetekhnoloji yayo ekhethekileyo, umgangatho ozinzileyo, iintlobo zenoveli kunye nezinye iimpawu, yile yesikhumba yangoku yezinga eliphezulu, kwaye ixabiso layo kunye nebakala alikho ngaphantsi kwesikhumba sokuqala. Isikhumba sePU kunye nesikhumba sokwenyani sineempawu zabo. Ukubonakala kwesikhumba sePU kuhle kwaye kulula ukuyinyamekela. Ixabiso liphantsi, kodwa alikwazi ukunxiba kwaye kulula ukuphuka; Isikhumba sokwenyani siyabiza, kunzima ukusihoya, kodwa sihlala ixesha elide.

(3) Ayixhathisi, kwaye inkangeleko yayo nokusebenza kwayo kusondele kwezo zesikhumba sendalo. Kulula ukuyihlamba, ukuyikhupha kunye nokuthunga.

4 Iindidi zihlukile kwaye ixabiso liphantsi.

(5) Ukufunxwa kwamanzi akukho lula ukwandisa kunye nokukhubazeka, kwaye kuyahambelana nokusingqongileyo.

02: Inkqubo yemveliso kunye nokuhlelwa

Isikhumba se-Nubuck: Emva kokuxutywa, ukukhanya okuphuzi kunye nombala, ubuso bayo bucutshungulwa kwinqanaba eliphezulu elifana neenwele ezintle zesikhumba se-suede. Njengoko luhlobo lwesikhumba esiphezulu, nangona amandla esikhumba nawo ayancipha yinkqubo yokudweba ukuya kwinqanaba elithile, kusenamandla kakhulu kunesikhumba esiqhelekileyo se-suede.

Isikhumba sehashe esiphambeneyo: Sinesandla esithambileyo, sibhetyebhetye kwaye somelele, sineenyawo ezinwebekayo, kwaye ulusu lutshintsha umbala xa lutyhalwa ngesandla. Kufuneka yenziwe ngofele lwesilwanyana olusentloko yendalo. Ngenxa yokuba ulusu lwehashe lunobushelelezi kunye namandla endalo, uninzi lwabo lusebenzisa ulusu lwehashe lwentloko. Nangona kunjalo, ngenxa yokuba le nkqubo yokwenziwa kwesikhumba ithatha ixesha elininzi, inezinto ezimbalwa eziluhlaza, kwaye ineendleko eziphezulu, i-Crazy horse yesikhumba ixhaphake kuphela kwimarike yesikhumba ephakathi kunye nephezulu.

Isikhumba sesipili sePU: umphezulu ugudile. Ulusu luphathwa ikakhulu ukwenza umphezulu ubengezela kwaye ubonise umphumo wesibuko. Ngoko ke, ibizwa ngokuba yisikhumba sesibuko. Izinto zayo azilungiswanga kakhulu.

I-Ultrafine fiber synthetic yesikhumba: luhlobo olutsha lwesikhumba sokwenziwa somgangatho ophezulu owenziwe ngeentsinga ezintle kakhulu. Abanye abantu bayibiza ngokuba sisizukulwana sesine sesikhumba sokwenziwa, esifaniswa nomgangatho ophezulu wesikhumba sendalo. Inokufunxwa kobumanzi kunye nokungena komoya kwesikhumba sendalo, kwaye ingaphezulu kwesikhumba sendalo ekuxhathiseni imichiza, ukumelana namanzi, ukuchasana nokungunda, njl.

Isikhumba esihlanjiweyo: Isikhumba se-retro PU, esasidumile kwiminyaka emibini edlulileyo, kukusebenzisa umaleko wepeyinti esekwe emanzini kwi-PU yesikhumba, emva koko wongeze iasidi ukuyihlamba emanzini ukutshabalalisa ubume bepeyinti kumphezulu wepeyinti. isikhumba esihlanjiweyo, ukwenzela ukuba iindawo eziphakanyisiweyo kumphezulu ziphele ukubonisa umbala ongasemva, ngelixa iindawo ze-concave zigcina umbala wokuqala. Isikhumba esihlanjiweyo senziwe. Inkangeleko kunye nokuziva kwayo kufana kakhulu nesikhumba. Nangona ingaphefumli njengesikhumba, ikhaphukhaphu kwaye inokuhlanjwa. Ixabiso layo liphantsi kakhulu kunesikhumba.

Ukufuma kwesikhumba esinyangwayo: Yimveliso yeplastiki eyenziwe yinkqubo ethile yokucubungula, engumxube we-polyvinyl chloride resin, i-plasticizer kunye nezinye izongezo, ezifakwe okanye zifakwe kumphezulu welaphu. Ukongeza, kukwakho nesikhumba sokwenziwa sePVC esinamacala aphindwe kabini kunye neengqimba zeplastiki kumacala omabini e-substrate.

Ulusu oludityanisiweyo: lwenziwa ngokongeza i-resin eguqulweyo kuluhlu lwe-PU kunye nomgangatho we-BASE wesikhumba, ukufunxwa, emva koko kusetyenzwa ukukhupha iphepha elingaphezulu okanye i-embossing, kunye nokushicilela. Emva koxinzelelo lwe-thermal yoshicilelo olushushu, umphezulu wolusu olushushu oludityanisiweyo lufakwe kwimpendulo efanayo ye-carbonization, ilinganisa uphawu olushiywe luthwathwa olutshisiweyo xa luvezwe kubushushu obuphezulu, okukhokelela kumbala omnyama wesikali sombala. Lobuso obucinezelweyo obushushu, ngoko bubizwa ngokuba yisikhumba esiciniweyo esishushu.
