I-Ultra high molecular weight polyethylene fiber (UHMWPE), eyaziwa nangokuthi i-PE fiber enamandla kakhulu, ingenye yezintambo ezintathu zobuchwepheshe obuphezulu emhlabeni namuhla (i-carbon fibre, i-aramid fiber, kanye ne-ultra-high molecular weight polyethylene fiber), kanye futhi i-fiber eqinile emhlabeni.Ilula njengephepha futhi iqinile njengensimbi, inamandla aphindwe izikhathi ezingu-15 kunensimbi, futhi iphindwe kabili kune-carbon fiber ne-aramid 1414 (Kevlar fiber).Njengamanje iyona nto eyinhloko yokukhiqiza amavesti angangenwa izinhlamvu.
Isisindo sayo samangqamuzana sisukela ezigidini ezingu-1,5 kuya kwezingu-8, okuphindwe izikhathi eziningi kunemicu evamile, okubuye kube umsuka wegama layo, futhi isebenza kahle kakhulu.
1. Isakhiwo siminyene futhi sinamandla amakhemikhali angenawo amandla, futhi izixazululo eziqinile ze-acid-base kanye nezincibilikisi zemvelo azinawo umthelela emandleni azo.
2. Ukuminyana kungamagremu angu-0.97 kuphela cubic centimeter ngayinye, futhi ingantanta phezu kwamanzi.
3. Izinga lokumuncwa kwamanzi liphansi kakhulu, futhi ngokuvamile akudingekile ukomisa ngaphambi kokwakhiwa nokucutshungulwa.
4. Inesimo sezulu esihle kakhulu sokumelana nokuguga kanye nokumelana ne-UV.Ngemuva kwamahora angu-1500 okuchayeka elangeni, izinga lokugcinwa kwamandla efayibha lisephezulu njenge-80%.
5. Inomphumela omuhle kakhulu wokuvikela emisebeni futhi ingasetshenziswa njengepuleti lokuvikela izimboni zamandla enuzi.
6. Ukumelana nezinga lokushisa eliphansi, isenayo i-ductility ezingeni lokushisa eliwuketshezi le-helium (-269 ℃), kuyilapho imicu ye-aramid ilahlekelwa ukusebenza kahle kokuvikela izinhlamvu ku -30 ℃;Ingakwazi futhi ukugcina amandla omthelela amahle kakhulu ku-nitrogen ewuketshezi (-195 ℃), isici amanye amapulasitiki angenaso, ngakho-ke ingasetshenziswa njengezingxenye ezimelana nezinga lokushisa eliphansi embonini yenuzi.
7. Ukumelana nokugqokwa, ukumelana nokugoba, kanye nokusebenza kokukhathala okuqinile kwe-ultra-high molecular weight polyethylene fibers nakho kunamandla phakathi kwamafayibha akhona asebenza kahle kakhulu, anokumelana nomthelela ovelele kanye nokuqina kokusika.I-ultra-high molecular weight polyethylene fiber eyikota kuphela ubukhulu bezinwele kunzima ukuyisika ngesikelo.Indwangu ecutshungulwayo kufanele isikwe kusetshenziswa umshini okhethekile.
8. I-UHMWPE iphinde ibe nokusebenza okuhle kakhulu kokufakwa kukagesi.
9. Ihlanzekile futhi ingenabuthi, ingasetshenziselwa ukuthintana nokudla nezidakamizwa.Uma kuqhathaniswa namanye amapulasitiki wobunjiniyela, imicu ye-polyethylene enesisindo esikhulu samangqamuzana ikakhulukazi ineziphambeko ezifana nokumelana nokushisa okuphansi, ukuqina, nobulukhuni, kodwa ingathuthukiswa ngezindlela ezinjengokugcwalisa nokuxhumanisa;Ngokombono wokumelana nokushisa, indawo yokuncibilika ye-UHMWPE (136 ℃) ngokuvamile iyafana naleyo ye-polyethylene evamile, kodwa ngenxa yesisindo sayo samangqamuzana amakhulu kanye ne-viscosity ephezulu yokuncibilika, kunzima ukusetshenzwa.
