Izisuka Zomlando Nezincazelo Eziyisisekelo: Izindlela Zobuchwepheshe Ezimbili Ezihlukene
Ukuze siqonde umehluko phakathi kwalokhu okubili, okokuqala sidinga ukulandelela imilando yazo yokuthuthuka, enquma ukucabanga kwazo okuyisisekelo kwezobuchwepheshe.
1. Isikhumba se-PVC: Iphayona Lesikhumba Sokwenziwa
Umlando wesikhumba se-PVC uhlehlela emuva ngekhulu le-19. I-Polyvinyl chloride (PVC), i-polymer material, yatholwa ngo-1835 ngusokhemisi waseFrance u-Henri Victor Regnault futhi yenziwa yinkampani yaseJalimane i-Griesheim-Elektron ekuqaleni kwekhulu lama-20. Nokho, ukusetshenziswa kwayo kweqiniso ekulingiseni isikhumba akuzange kuqale kwaze kwaba yiMpi Yezwe II.
Impi yaholela ekuswelekeni kwezinsiza, ikakhulukazi isikhumba semvelo. Isikhumba semvelo ngokuyinhloko sasinikezwa amasosha, okushiya imakethe yabantu abavamile inciphe kakhulu. Leli gebe elibalulekile lezidingo likhuthaze ukuthuthukiswa kwezinye izindlela. AmaJalimane aphayona ukusetshenziswa kwe-PVC eboshwe phezu kwesisekelo sendwangu, okwenza isikhumba sokwenziwa sokuqala emhlabeni. Le nto, enokumelana kwayo okuhle kakhulu namanzi, ukuqina, nokuhlanzeka kalula, yathola ukusetshenziswa ngokushesha ezindaweni ezifana nemithwalo nezicathulo zezicathulo.
Incazelo Eyisisekelo: Isikhumba se-PVC yinto efana nesikhumba eyenziwe ngokunameka noma nge-calendering ungqimba lwengxube yenhlaka efana nokunamathisela ye-polyvinyl chloride resin, ama-plasticizers, stabilizers, and pigments on the substrate yendwangu (njengezindwangu ezilukiwe, ezilukiwe, nezingezona ezilukiwe). Izinto ezisetshenziswayo zibe sezibhekana nezinqubo ezifana ne-gelation, ukwenza amagwebu, ukufaka embossing, nokwelashwa kwendawo. Umnyombo wale nqubo usekusetshenzisweni kwe-polyvinyl chloride resin.
2. Isikhumba se-PU: Isifiki Esiseduze Nesikhumba Sangempela
Isikhumba se-PU savela cishe emashumini amabili eminyaka ngemva kwe-PVC. I-polyurethane (PU) chemistry yasungulwa ngusokhemisi waseJalimane u-Otto Bayer kanye nozakwabo ngo-1937 futhi yathuthukiswa ngokushesha ngemva kweMpi Yezwe II. Ukuthuthuka kwezobuchwepheshe bamakhemikhali ngeminyaka yawo-1950 kanye nawo-1960 kwaholela ekuthuthukisweni kwesikhumba sokwenziwa kusetshenziswa i-polyurethane.
Ubuchwepheshe besikhumba bokwenziwa be-PU baba nentuthuko esheshayo e-Japan naseNingizimu Korea ngeminyaka yawo-1970. Ikakhulukazi, izinkampani zaseJapane zenze izindwangu ze-microfiber (ezifushanisiwe ngokuthi "isikhumba se-microfiber") nge-microstructure efana kakhulu nesikhumba sangempela. Ukuhlanganisa lokhu ne-polyurethane impregnation nezinqubo zokumboza, bakhiqize "isikhumba se-microfiber PU," ukusebenza kwayo kufana kakhulu nesikhumba sangempela futhi kuyasidlula kwezinye izici. Lokhu kubhekwa njengenguquko kubuchwepheshe besikhumba bokwenziwa.
Incazelo Eyisisekelo: Isikhumba se-PU yinto efana nesikhumba eyenziwe ngesisekelo sendwangu (evamile noma i-microfiber), ehlanganiswe noma efakwe ungqimba lwe-polyurethane resin, elandelwa ukomiswa, ukuqina, nokwelashwa kwendawo. Umnyombo wale nqubo ulele ekusetshenzisweni kwe-polyurethane resin. I-PU resin i-thermoplastic ngokwemvelo, evumela ukucutshungulwa okuvumelana nezimo nokusebenza okuphezulu komkhiqizo.
Isifinyezo: Ngokomlando, isikhumba se-PVC savela "njengokunikezwa kwezimo eziphuthumayo ngesikhathi sempi," kuxazululwa inkinga yokutholakala. Isikhumba se-PU, ngakolunye uhlangothi, siwumkhiqizo wokuthuthuka kwezobuchwepheshe, okuhloswe ngaso ukubhekana nenkinga yekhwalithi kanye nokuphishekela ukubukeka okucishe kufane kwesikhumba sangempela. Lesi sisekelo somlando sibe nomthelela omkhulu ezindleleni zokuthuthuka ezalandela kanye nezici zomkhiqizo wakho kokubili.
