Umsebenzi osindayo Oweluliwe ngaphambili intambo ye-uhmwpe elukiwe eyi-12 yokubopha umkhumbi

Imele ini i-UHMWPE?

I-UHMWPE imele i-ultra high molecular weight polyethylene. Ungase futhi uzwe kuthiwa yi-HMPE, noma ngamagama emikhiqizo afana ne-Spectra, Dyneema noma i-Stealth Fibre. I-UHMWPE isetshenziswa emigqeni esebenza kahle kakhulu kuzo zonke izimboni ezihlukahlukene, ezihlanganisa olwandle, ukudoba ngenjongo yokuthengisa, ukugibela izintaba, kanye nezilwane zasemanzini. Inezimfanelo eziningi ezenza kube ukukhetha okuhle kakhulu ezindaweni ezimanzi; ilula ngokwanele ukuntanta, i-hydrophobic (ixosha amanzi) futhi ihlala iqinile emazingeni okushisa aphansi. Uzoyithola isetshenziswa ku-yachting, ikakhulukazi oseyili nokugxumeka, njengoba ukunwebeka kwayo okuphansi kuvumela oseyili bagcine isimo esihle ngesikhathi besakwazi ukumelana nokuhuzuka.Ngamandla ayo aphezulu nesilinganiso sesisindo, ukuphatha okushelelayo kanye nezakhiwo ezinwebekayo eziphansi, iyakwazi iyintambo yokuzikhethela kolayini bokusiza umkhumbi, izinsimbi zasolwandle kanye namathangi. Idume kakhulu ekuqondiseni imikhumbi ezimeni ezicindezelayo.

Yiziphi izici zobuchwepheshe ze-UHMWPE?

I-UHMWPE iyifayibha ye-polyolefin, ehlanganisa amaketango amade kakhulu e-polyethylene agqagqene, aqondaniswe ohlangothini olufanayo, okuyenza ibe ngenye yezinketho zezintambo eziqine kakhulu ezitholakalayo.
Ngenxa yesakhiwo sayo samangqamuzana, i-UHMWPE imelana namakhemikhali amaningi, ahlanganisa okokuhlanza, ama-acid amaminerali kanye namafutha. Kodwa-ke, ingagqwala ngama-oxidising agents aqinile.Imicu ye-HMPE inobukhulu obungu-0.97 g cm−3 kuphela futhi ine-coefficient yokungqubuzana ephansi kunenylon ne-acetal. I-coefficient yayo ifana neye-polytetrafluoroethylene (Teflon noma PTFE), kodwa inokumelana nokuhuzuka okungcono kakhulu.

Imicu eyenza i-Ultra High Molecular Weight Polyethylene inephuzu lokuncibilika eliphakathi kuka-144°C no-152°C, eliphansi kuneminye imicu ye-polymer eminingi, kodwa ayinakho ukuphuka lapho ivivinywa ezingeni lokushisa eliphansi kakhulu (-150°C. ). Izintambo eziningi ngeke zikwazi ukugcina ukusebenza kwazo emazingeni okushisa angaphansi kuka -50°C. Ngakho-ke intambo ye-UHMWPE iyanconywa ukuthi isetshenziswe phakathi kuka -150 kanye +70 °C, njengoba ingeke ilahlekelwe yinoma yiziphi izici zesisindo samangqamuzana aphezulu kulolu hlu.
I-UHMWPE empeleni ithathwa njengepulasitiki yobunjiniyela ekhethekile, esetshenziselwa eminye imisebenzi eminingi ngale kokukhiqiza izintambo. Eqinisweni, i-UHMWPE yebanga lezokwelapha isetshenziswe iminyaka eminingi ekufakweni kwamalunga, ikakhulukazi ekufakweni esikhundleni kwamadolo nenyonga. Lokhu kungenxa yokungqubuzana kwayo okuphansi, ukuqina, amandla omthelela aphezulu, ukumelana namakhemikhali abolayo kanye nokuvumelana okuhle kakhulu kwe-biocompatibility.

Ungase umangale ukwazi ukuthi ipulasitiki ye-UHMW nayo iyinketho ethandwayo yezikhali zomzimba ngamasosha namaphoyisa, futhi ngenxa yokumelana kwayo okuphezulu nesisindo esiphansi.

Ngaphezu kwezimfanelo zayo zamandla ahlaba umxhwele, i-UHMWPE ayinambitheki, ayinabuthi futhi ayinaphunga, yingakho le pulasitiki ivame ukusetshenziswa ezitshalweni zokukhiqiza ukudla nasekukhiqizeni. Kuphephile kubo bobabili abasebenzisi bokugcina nabasebenzi bokukhiqiza.

Yiziphi izakhiwo ze-UHMWPE?

Izakhiwo eziphakeme ze-UHMWPE zihlanganisa: Indawo encibilikayo ephezulu (ngaphezu kuka-144°C) I-Low density - intanta emanzini olwandle Isisindo esiphansi  Iphephe kunocingo - iphuka ngendlela yomugqa  Ukusebenza okuphezulu  Ukumuncwa komswakama omncane (kuxosha amanzi)  Ukumelana namakhemikhali (ngaphandle kwama-oxidising acid) Amandla aphezulu - aqine kunensimbi eqinile Ukumelana ne-UV - ukwandisa impilo yentambo yakho Izigcoba ngokwazo - i-coefficient ephansi yokungqubuzana  I-Superior abrasion resistance  I-Ultra-low stretch (3-4% lapho iphuka umthwalo) Izindleko ezincishisiwe uma kuqhathaniswa nentambo yensimbi Low dielectric constant - cishe icace ku-radar Vibration damping Ukunakekelwa okuphansi I-conductivity kagesi ephansi  Ukukhathala okuguquguqukayo okuhle kakhulu Lezi zintambo ezisebenza kahle kakhulu ziya ngokuya zisetshenziswa ukushintsha insimbi nemicu evamile. Ziqine kakhulu kunensimbi kodwa ziyi-1/8 kuphela yesisindo sezintambo zensimbi ezifanayo. Ngamanye amazwi, zinamandla okungenani izikhathi ezingu-8 kunezintambo zensimbi. Imigqa ye-polyethylene ye-molecular high (UHMWPE) izacile, ilula futhi iyazithambisa, ngakho kubaluleke kakhulu ukubamba kunezintambo zensimbi ezivamile. Ngaphezu kwamandla abo, aphinde aphephe kakhulu, anamandla amancane okuhlehla kunentambo yensimbi. Lapho intambo yensimbi igqashuka, intambo yensimbi iyaqaqeka ngokushesha, ishiye imiphetho ebukhali insingo izungeza ngendlela engalindelekile. Uma intambo ye-UHMWPE igqashuka, ukuhlehla kuba kuncane kakhulu. Ngenxa yokwakhiwa kwayo kwamaketanga amade e-polyethene aqondaniswe ohlangothini olufanayo, uma ephuka (okungenakwenzeka ngenxa yamandla ayo esibopho), intambo izobonisa ukuhlehla okuqondile, okubikezelwe. Imicu yokuzithambisa ye-UHMWPE iphinde ibe nesibambo se-waxy nendawo ebushelelezi, ikwenze kube lula ukuyiphatha, nakuba lokhu kusho ukuthi ayiwabambeli kahle amafindo. Nokho naphezu kokushelela kwawo, asakwazi ukumelana nokuhuzuka okungenani izikhathi ezingu-15 kune-carbon steel. Okokugcina, uma kuqhathaniswa nentambo yensimbi noma ezinye izintambo ze-polyester, izintambo ze-UHMWPE zincane ngevolumu ngenxa yobuningi obudingekayo ukuze kuzuzwe umphumela ofanayo. Lokhu kwenza kube lula ukuwagcina.
