Mayelana nezintambo ze-UHMW-PE

Intambo iFrankstar Dyneema (i-polyethylene fiber enesisindo sama-molecule esiphezulu kakhulu) ihlanganisa izici zesisindo esilula kanye namandla aphezulu kakhulu. Ubuningi bayo buphansi kunobamanzi, okuvumela ukuthi intante ngokwemvelo phezu kwamanzi. Intambo ye-UHMW-PE iyinto efanelekile yokusebenza kahle ezindaweni zasemanzini nasezindaweni ezigqwala kakhulu. Ngokumelana kwayo nesimo sezulu okuvelele kanye nokuqina kwamakhemikhali, ingamelana nezinselele ezinzima zemvelo njengemisebe ye-ultraviolet, umswakama, kanye nokugqwala kwe-acid ne-alkali ngaphandle kokwelashwa okwengeziwe, futhi isetshenziswa kabanzi kwezobunjiniyela basemanzini, ekuhloleni ucwaningo lwesayensi, kanye nasemasimini ezimboni.

Izici

Isetshenziswa kakhulu emanetheni okudoba nge-plankton, ingahlinzeka ngokuntanta okungaguquki, futhi amandla okuthwala imithwalo aphansi kunezintambo ze-Kevlar.

Amandla Aphezulu: Ngokwesisindo nesisindo, i-Dyneema inamandla ngokuphindwe ka-15 kunentambo yensimbi.

Isisindo Esilula: Usayizi ngosayizi, intambo eyenziwe nge-Dyneema ilula ngokuphindwe kasishiyagalombili kunentambo yensimbi.

Imelana namanzi: I-Dyneema ayithandi amanzi futhi ayimunci amanzi, okusho ukuthi ihlala ilula uma isebenza ezindaweni ezimanzi.

Iyantanta: I-Dyneema ine-Specific Gravity engu-0.97 okusho ukuthi iyantanta emanzini (amandla adonsela phansi athile ayisilinganiso sobuningi. Amanzi ane-SG engu-1, ngakho-ke noma yini ene-SG<1 izontanta kanti i-SG>1 isho ukuthi izocwila).

Ukumelana namakhemikhali: I-Dyneema ayisebenzi ngamakhemikhali, futhi isebenza kahle ezimweni ezomile, ezimanzi, ezinosawoti nezinomswakama, kanye nezinye izimo lapho kukhona khona amakhemikhali.

Imelana ne-UV: I-Dyneema inokumelana okuhle kakhulu nokuwohloka kwesithombe, igcina ukusebenza kwayo uma ivezwa ekukhanyeni kwe-UV. Amandla Aphezulu: Ngokwesisindo nesisindo, i-Dyneema inamandla ngokuphindwe ka-15 kunentambo yensimbi.

Izakhiwo zomzimba zemicu ye-polyethylene enamandla amakhulu kanye ne-modulus ephezulu zinhle kakhulu. Ngenxa yobukristali bayo obuphezulu, iyiqembu lamakhemikhali okungelula ukusabela ngama-chemical agents. Ngakho-ke, imelana namanzi, umswakama, ukugqwala kwamakhemikhali, kanye nemisebe ye-ultraviolet, ngakho-ke asikho isidingo sokwelashwa ngokumelana ne-ultraviolet. Ukumelana nokugqwala, ukumelana ne-asidi kanye ne-alkali, ukumelana okuhle kakhulu kokuklwebheka, ayigcini nje ngokuba ne-modulus ephezulu, kodwa futhi ithambile, inokuphila isikhathi eside kokugoba, iphuzu lokuncibilika kwe-polyethylene fiber enamandla aphezulu iphakathi kuka-144 ~ 152C, ivezwe endaweni engu-110C isikhathi esifushane ngeke ibangele ukuwohloka okukhulu kokusebenza, njll.

Ipharamitha Yobuchwepheshe
