2.1 Polypropylene fiber ntau pob zeb
Los ntawm kev tshawb fawb qhov teeb meem nyob rau hauv xyoo tas los no, nws tuaj yeem pom tau tias polypropylene fiber reinforced pob zeb yog cov khoom siv dav siv fiber ntau ntxiv.Kev tshawb fawb nyob rau hauv tsev thiab txawv teb chaws tsom rau lub cev thiab txhua yam khoom ntawm fiber ntau pob zeb, uas muaj compressive kuj, dabtsi yog khoov kuj, toughness, impermeability, thermal stability, shrinkage thiab kev tsim kho kev ua tau zoo.Cov kev tshawb fawb tau pom tias piv nrog cov qauv ntsuas, nrog qhov nce ntawm fiber ntau piv (0% ~ 15%), lub zog compressive ntawm fiber ntau hloov me ntsis, lub zog flexural nce los ntawm 12% ~ 26%, thiab lub toughness kuj. nce.Sun Jiaying tau kawm txog lub zog flexural, brittleness thiab cuam tshuam tsis kam ntawm cov pob zeb ua haujlwm siab nrog ntau npaum li cas ntawm polypropylene fiber.Dai Jianguo thiab Huang Chengkui tau kawm cov txiaj ntsig ntawm kev tsim kho, compressive thiab khoov tsis kam, toughness, impermeability, tshav kub laus stability thiab shrinkage ntawm mesh polypropylene fiber ntau pob zeb.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov ntawm polypropylene fiber ntau, Zhu Jiang soj ntsuam lub waterproof mechanism ntawm polypropylene fiber ntau pob zeb, thiab qhia txog kev tsim kho ntawm ntxiv polypropylene fiber rau hauv qab daus pem teb ntawm Guangzhou Tshiab Tuam Tshoj Tsev thiab Guangzhou South Industrial Building.Gu Zhangzhao, Ni Mengxiang thiab lwm tus tau taw qhia tias nylon thiab polypropylene fiber ntau pob zeb muaj qhov ua kom tawg tau zoo, uas tuaj yeem txhim kho kev ua haujlwm thiab ua haujlwm ntev ntawm cov pob zeb, thiab tau ua tiav kev txhawb nqa thiab siv hauv Shanghai 80,000 chaw ntau pob, subway projects thiab Oriental Pearl TV Ntauwd. thiab lwm qhov project.
Nyob rau hauv xyoo tas los no, hauv Tebchaws Meskas, Tebchaws Askiv, Nyij Pooj thiab Tebchaws Europe sab hnub poob, daim ntawv thov nplai ntawm fiber ntau pob zeb tau maj mam nthuav dav, thiab polypropylene fiber ntau pob zeb yog thawj zaug siv hauv tub rog engineering hauv Tebchaws Meskas thaum xyoo 80s ntawm lub xyoo pua 20th, thiab ces sai sai tsim mus rau hauv civilian engineering.Los ntawm qhov xwm txheej tsis ntev los no ntawm kev tshawb fawb txawv teb chaws, kev tshawb fawb ntawm polypropylene fiber ntau pob zeb tau txuas ntxiv mus rau qee yam raws li kev tshawb fawb txog kev ua tau zoo.Sydney Furlan Jr. et al.ua kev ntsuam xyuas shear ntawm kaum plaub kab teeb, taw qhia tias lub zog shear, nruj (tshwj xeeb tshaj yog tom qab thawj lub sij hawm tawg) thiab toughness tau zoo dua piv nrog cov kab teeb ci, thiab kuj tau kawm txog cov txiaj ntsig ntawm stirrups ntawm fiber ntau cov kab teeb.GD Manolis et al.kuaj cov kev cuam tshuam thiab kev vibration ntawm tus kheej lub sij hawm ntawm ib tug series ntawm polypropylene fiber ntau pob zeb slabs nrog fiber ntau cov ntsiab lus thiab cov kev txhawb nqa sib txawv, thiab pom tias qhov cuam tshuam tsis kam ntawm cov pob zeb pob zeb los ntawm kev qhia cov fibers maj mam nce nrog cov ntsiab lus fiber ntau, tab sis yeej tsis muaj kev cuam tshuam rau lub sijhawm ntawm tus kheej vibration.
Laizhou Kaihui Machinery Co., Ltd yog cov chaw tsim khoom lag luam ntawmpob zeb fiber ntau extrusion kab.Txais tos tiv tauj peb kom tau txais xov xwm ntxiv.
