Izinto zokusetshenziswa: i-polyamide, i-polypropylene ne-polyester.Intambo ngayinye yenziwe ngemicu emincane kakhulu.Okulandelayo yisingeniso semicu eyinhloko esiyisebenzisayo nezici zayo.
Izinto ezisetshenziswa njalo
I-Polyamide iyifayibha esetshenziswa kakhulu, esetshenziselwa ukwenza izintambo zekhwalithi ephezulu ngezinto zokwenziwa.Izinhlobo ezijwayeleke kakhulu ze-polyamide yi-DuPont inayiloni (PA 6.6) ne-Perlon(PA 6).I-Polyamide ayigugi, inamandla kakhulu futhi iyanwebeka kakhulu.Kungashiswa futhi kumise unaphakade-lesi sici sisetshenziswa enqubweni yokulungisa ukushisa.Ngenxa yesidingo sokumunca amandla, intambo yamandla yenziwe ngokuphelele nge-polyamide.I-Polyamide fibre nayo isetshenziswa kabanzi ukwenza izintambo ezimile, nakuba uhlobo lwezinto ezibonakalayo ezinokwelula okuncane kukhethwa.Ububi be-polyamide ukuthi imunca amanzi amaningi uma kuqhathaniswa, okuzoyibangela ukuba inciphe uma iba manzi.
Ngenxa yokuthi iyi-polypropylene, inesisindo esincane kakhulu.
I-Polypropylene ilula futhi ishibhile.Ngenxa yokumelana nokugqokwa okuphansi, i-polypropylene isetshenziswa kakhulu ukwenza izintambo zezintambo, ezivikelwe ngamashethi e-polyamide.I-Polypropylene inesisindo esilula kakhulu, iphansi ngokuminyana futhi ingantanta.Yingakho siyisebenzisa ukwenza intambo yethu yokusakaza.
Ukusetshenziswa kwe-polyester
Izintambo ezimile ezenziwe ngemicu ye-polyester zisetshenziselwa ikakhulukazi imisebenzi engase ihlangane nama-asidi noma amakhemikhali abolayo.Ngokungafani ne-polyamide, inokumelana ne-asidi ephakeme futhi ayiwamumbi neze amanzi.Kodwa-ke, i-polyester fiber inezici zokumunca amandla ezinomkhawulo kuphela, okusho ukuthi ukusebenza kwayo ku-PPE kunomkhawulo.
Thola amandla aphezulu ezinyembezi.
I-Dynema rope I-Dynema iyintambo yefayibha yokwenziwa eyenziwe nge-ultra-high molecular weight polyethylene.Inamandla aphezulu kakhulu okukhala kanye nobude obuphansi kakhulu.Ibalwa ngesilinganiso sesisindo, amandla ayo aqinile aphindwe izikhathi ezingu-15 kunensimbi.Izici zayo eziyinhloko ukumelana nokugqoka okuphezulu, ukuzinza okuphezulu kwe-ultraviolet nesisindo esilula.Kodwa-ke, intambo ye-Dyneema ayihlinzeki nganoma yikuphi ukumuncwa kwamandla okuguquguqukayo, okwenza kungafaneleki okokusebenza kokuzivikela komuntu siqu.Intambo ye-Dyneema isetshenziswa kakhulu ukudonsa izinto ezinzima.Zivame ukusetshenziswa esikhundleni sezintambo zensimbi ezinzima.Ngokwenza, indawo yokuncibilika yentambo yeDyneema iphansi kakhulu.Lokhu kusho ukuthi imicu ye-Dynema rope Dynema (ultra-high molecular weight polyethylene rope) ingase yonakaliswe uma izinga lokushisa lingaphezu kuka-135 degrees Celsius.
Incazelo ephelele yokusika ukumelana.
I-Aramid iyifayibha eqinile kakhulu futhi ekwazi ukumelana nokushisa enokumelana nokusika okuphezulu.Njengentambo ye-Dyneema, intambo ye-aramid ayinikezi ukumuncwa kwamandla aguqukayo, ngakho ukusebenza kwayo ku-PPE kunomkhawulo.Ngenxa yokuzwela kwayo okwedlulele ekugobeni nasekumelaneni ne-ultraviolet ephansi, imicu ye-aramid ivame ukunikezwa imigoqo ye-polyamide ukuze ivikeleke.Sisebenzisa intambo ye-aramid ukuze sisebenze entanjeni yesistimu ukuze kumiswe umsebenzi, okudinga ukunwebeka okuncane kanye nokumelana nokusika okuphezulu.
