2.2 Ikhonkrithi yefayibha yenayiloni

Ikhonkrithi yefayibha yenayiloni yenye yeentsinga zokuqala zepolymer ezazisetyenziswa kwisamente kunye nekhonkrithi, ixabiso liphezulu ngokwentelekiso, kwaye isicelo silinganiselwe.Ukufakwa kwefiber ye-nylon kunokunciphisa kakhulu ixabiso le-shrinkage eyomileyo yekhonkrithi, kodwa i-flexural, i-compressive, i-axial pressure, i-elastic mold kunye ne-stress-strain properties ayifani kakhulu nekhonkrithi eqhelekileyo, kwaye ukungasebenzi kunye nokusebenza kwe-rust inhibition kuphuculwe kakhulu; ngaloo ndlela kuphuculwe ukuqina kwekhonkrithi.

Xa ixabiso elincinci le-nylon fiber (i-0.052%) yongezwa kwikhonkrithi, i-matrix yekhonkrithi inokufumana isiphumo esibalulekileyo sokuphucula ukusebenza kwe-non-structural, ukunciphisa kakhulu i-plastic shrinkage cracks yekhonkrithi, kunye nokuphucula ukuxhathisa impembelelo yekhonkrithi.Xa i-dosage inyuswa ukuya kwi-0.26%, ukuchasana kwempembelelo yekhonkrithi kunokunyuswa kakhulu.Ifayibha yenylon inokuphucula ukuxhathisa kweqabaka yekhonkrithi, inqanda ukulahleka kwamandla ekhonkrithi, kwaye iphucule imbonakalo yesiqwenga sovavanyo.Wan Zhongxiang et al.bakholelwa ukuba oku kubangelwa ukufakwa kweentambo ze-nylon zokunciphisa iintanda ezibangelwa uxinzelelo lwangaphakathi lwekhonkrithi, kunye nokunyuka komxholo wegesi wekhonkrithi, kunye nokunyuka koxinzelelo oluchasayo kunye noxinzelelo lwe-osmotic.Baye bafumanisa ukuba ikhonkrithi efakwe nge-0.5% yevolumu yefayibha yenylon yokunciphisa ilahleko yemodulus eguqukayo kunye nokulahleka kobunzima nge-10.5% kunye ne-1.7%, ngokulandelelana, xa kuthelekiswa nekhonkrithi yebhentshi emva kwe-300 yomjikelo wokunyibilika komkhenkce.

2.3 Polyethylene ifayibha ikhonkrithi

Ngenxa yemodyuli ephantsi ye-elasticity, i-polyethylene fiber ayizange isetyenziswe kwii-composites zesamente ukuza kuthi ga ngoku, kwaye ayifundwanga kakuhle.I-KCG Ong, M. Basheerkhan, P. Paramasivam kuvavanyo lwempembelelo ephantsi kwesantya se-polyethylene fiber concrete slab, kwi-fiber content ye-0.5%, i-1% kunye ne-2%, ixabiso lamandla lokuphuka linyuke nge-19%, 53% kunye ne-80. %, ngokulandelelanayo.Nangona ezi xabiso zincinci kunexabiso le-fiber fibre zekhonkrithi ezinomxholo ofanayo (amaxabiso e-fiber fiber concrete slabs yi-40%, 100% kunye ne-136%, ngokulandelanayo), ixabiso labo lincinci kakhulu kune-fiber fiber, ukuba i-elastic. Imodyuli efikelela kwi-70GN/m2 inokuphuhliswa ifayibha enwebekayo ephezulu yokungunda ipolyethylene, olusinga olungabizi kakhulu lunamandla amakhulu kwimixube yesamente.

ILaizhou Kaihui Machinery Co., Ltd ngumvelisi oqeqeshiweyo weumgca wekhonkrithi wefiber extrusion.Wamkelekile ukuba uqhagamshelane nathi ukufumana ulwazi oluthe kratya.
