Uyini umehluko phakathi kwentambo ye-Dalima kanye ne-ultra-high molecular polyethylene?

Intambo yomucu owodwa we-Dalima PE isebenzisa intambo eluhlaza ye-polyethylene (uhmwpe) enomucu owodwa, futhi intambo ye-polyethylene ephezulu kakhulu yemolekyuli ikhiqizwa kusetshenziswa ubuchwepheshe obusha bokuhlanganisa obungenamluko. Inezinzuzo zokubukeka okushelelayo kocingo olulodwa lwenayiloni namandla okudonsa aqinile ocingo olulukiwe lwe-PE. , elivame ukubizwa ngokuthi ihhashi eliqinile ngaphandle kokuluka, elaziwa nangokuthi ihhashi eliqinile elinentambo eyinhloko.

I-polyethylene yesisindo se-molecular (uhmwpe) inamandla okubamba aqine kakhulu emhlabeni, ayikho enye into engakwazi ukuhambisana nayo. Yakhiqizwa ngempumelelo e-Netherlands futhi yabhaliswa njenge-Dyneema: ezimbili zathuthukiswa e-United States futhi zaqanjwa ngokuthi i-Spectra, kanti i-China yaba izwe lesithathu ukuyithuthukisa ngempumelelo. Ihlanganisa ikakhulukazi intambo ye-nayiloni ye-PA, intambo ye-PE eyodwa yomucu, intambo ephothiweyo ye-PE Dalima, inqubo ekhethekile enwetshiwe futhi emise okwentambo yedayimane ye-PE (ama-braids ama-4), i-PE laser wire (ama-braids ayi-8), i-PE diamond wire (ama-braids angu-16), nezintambo zokudonsa. Kunezinhlobo eziningi zezintambo zokudoba ezinezincazelo ezahlukene, ezingahlangabezana ngokugcwele nezidingo ezihlukahlukene zezindawo ezahlukene zamanzi. Abaningi abathanda ukudoba basebenzise ngempumelelo imikhiqizo yezintambo zokudoba iminyaka eyi-10, okufana nemikhiqizo yezintambo zokudoba esezingeni eliphezulu, esebenza kahle kakhulu.

Intambo ephothiweyo ye-Dalima: Intambo yokudoba elukwe kusuka emiculweni engaphezu kwemi-4 ye-ultra-high molecular weight polyethylene (uhmwpe) fiber. Imiluko evamile yehhashi lika-Dali imiluko engu-4, imiluko engu-6, imiluko engu-8, nemiluko engu-16. Inamandla aphezulu okudonsa kanzima (izikhathi ezi-5 kunayiloni) kanye nokumelana nokugqokwa okukhulu, kodwa ngenxa yokweluka i-fiber, imunca kalula amanzi, kuthinte ukuzwela kwayo nokusebenza kokusika amanzi. Ngokuthuthukiswa kwemboni yesimanje yokudoba, izintambo zomlilo (izintambo ezi-4 ezihlanganisiwe ezihlanganisiwe), izintambo zedayimane ze-Dyneema (i-4 braided stretch and shape elastic), izintambo ze-Dyneema laser (ama-4 braids, anwetshiwe futhi anwebekayo), azwela kakhulu, ashesha ukusika amanzi, futhi angathathi amanzi, athathwe. Ama-braids angu-8 (ane-pull-back kanye nokubunjwa okunwebekayo), i-Dalima-strand single (imicu eyodwa ayilukiwe).

Umkhiqizo uphezulu ngo-0%. Amandla acishe abe ngama-44 aphakeme kunawaseCaif, okuphindwe kabili kunawamanje emhlabeni. 9. Ukuminyana komugqa.
