2.2 Ukhonkolo wefayibha enayiloni

Ukhonkolo wefayibha enayiloni ungomunye wemicu ye-polymer yokuqala eyayisetshenziswa kusimende nokhonkolo, intengo iphakeme uma kuqhathaniswa, futhi isicelo sinomkhawulo.Ukufakwa kwe-nylon fiber kunganciphisa kakhulu inani le-shrinkage elomile likakhonkolo, kodwa ukuguquguquka, ukucindezela, ukucindezela kwe-axial, isikhunta esinwebekayo kanye nezakhiwo ze-stress-strain azihlukani kakhulu nokhonkolo ojwayelekile, futhi ukusebenza okungenakunyakaziswa nokugqwala kuthuthukiswa kakhulu, ngaleyo ndlela kuthuthukisa ukuqina kukakhonkolo.

Uma inani elincane lefayibha yenayiloni (0.052%) yengezwa kukhonkolo, i-matrix kakhonkolo ingathola umphumela obalulekile wokuthuthukisa ukusebenza okungenasakhiwo, yehlise kakhulu imifantu yokushwabana kwepulasitiki kakhonkolo, futhi ithuthukise ukumelana komthelela kakhonkolo.Lapho umthamo unyuswa waba ngu-0.26%, ukumelana komthelela kakhonkolo kungakhula kakhulu.Ifayibha enayiloni ingathuthukisa ukumelana nesithwathwa sikakhonkolo, ivimbele ukulahleka kwamandla kakhonkolo, futhi ithuthukise ukubukeka kwesiqephu sokuhlola.Wan Zhongxiang et al.bakholelwa ukuthi lokhu kubangelwa ukufakwa kwezintambo ze-nylon ukuze kuncishiswe imifantu ebangelwa ukucindezeleka kwangaphakathi kokhonkolo, kanye nokwanda kokuqukethwe kwegesi kakhonkolo, kanye nokwanda kwengcindezi yokulwa nokwandisa nokucindezela kwe-osmotic.Bathole ukuthi ukhonkolo ofakwe nge-0.5% yevolumu yefayibha enayiloni yehlise ukulahleka kwemodulus okunwebeka okuguquguqukayo nokulahleka kwesisindo ngo-10.5% no-1.7%, ngokulandelana, uma kuqhathaniswa nokhonkolo webhentshimakhi ngemva kwemijikelezo engu-300 yokuqandisa.

2.3 Ukhonkolo we-polyethylene fiber

Ngenxa ye-modulus yayo ephansi yokunwebeka, i-polyethylene fiber ibingavamile ukusetshenziswa ezinhlanganisela zikasimende kuze kube manje, futhi ayizange ifundwe kahle.I-KCG Ong, M. Basheerkhan, P. Paramasivam ekuhlolweni komthelela wejubane eliphansi le-polyethylene fiber concrete slab, okuqukethwe kwefayibha engu-0.5%, 1% no-2%, inani lamandla okuphuka lenyuke ngo-19%, 53% no-80 %, ngokulandelana.Nakuba lezi zindinganiso zincane kunamanani ama-slabs okhonkolo we-fiber fiber okuqukethwe okufanayo (amanani ama-slabs e-steel fibre ukhonkolo angama-40%, 100% no-136%, ngokulandelana), intengo yawo incane kakhulu kune-fiber yensimbi, uma i-elastic. i-modulus efika ku-70GN/m2 ingathuthukiswa i-high elastic mold polyethylene fiber, le fibre eshibhile inamandla amakhulu emkhakheni wezinhlanganisela zikasimende.

I-Laizhou Kaihui Machinery Co., Ltd ingumkhiqizi ochwepheshe weumugqa we-fiber extrusion ukhonkolo.Siyakwamukela ukuxhumana nathi ukuze uthole ulwazi olwengeziwe.
