Ke kūlana noiʻi a me ka noi ʻana o ka Organic Synthetic Fiber Concrete

2.1Polypropylene fiber concrete
Mai ke kūlana noiʻi i nā makahiki i hala iho nei, hiki ke ʻike ʻia ʻo ka polypropylene fiber reinforced concrete ka mea i aʻo nui ʻia i ka fiber reinforced concrete material.ʻO ka noiʻi ma ka home a me nā ʻāina ʻē e kālele ana i nā waiwai kino a me nā mechanical o ka fiber concrete, e pili ana i ke kūpaʻa compressive, ke kūlou ʻana, ka paʻakikī, ka impermeability, ke kūpaʻa wela, ka emi ʻana a me ka hana hana.Ua hōʻike nā haʻawina i ka hoʻohālikelike ʻia me ka benchmark benchmark, me ka piʻi ʻana o ka ratio volume fiber (0% ~ 15%), ke loli liʻiliʻi ka ikaika compressive o ka fiber concrete, piʻi ka ikaika flexural e 12% ~ 26%, a me ka paʻakikī pū kekahi. mahuahua.Ua aʻo ʻo Sun Jiaying i ka ikaika flexural, brittleness a me ka pale ʻana i ka hopena o ke koki hana kiʻekiʻe me ka nui o ka polypropylene fiber.Ua aʻo ʻo Dai Jianguo lāua ʻo Huang Chengkui i nā hopena hoʻāʻo o ke kūkulu ʻana i ka hana, compressive a me ke kūlou ʻana, ka paʻakikī, ka impermeability, ka paʻa ʻana o ka wela a me ka emi ʻana o ka mesh polypropylene fiber concrete.

Ma nā ʻōlelo o ka noi ʻana o ka fiber polypropylene, ua loiloi ʻo Zhu Jiang i ka mīkini wai o ka polypropylene fiber concrete, a hoʻolauna i ke kūkulu ʻana i ka hoʻohui ʻana i ka fiber polypropylene i ka papahele haʻahaʻa o Guangzhou New China Building a me Guangzhou South Industrial Building.Ua kuhikuhi ʻo Gu Zhangzhao, Ni Mengxiang a me nā mea ʻē aʻe i ke kūʻē ʻana o ka nylon a me ka polypropylene fiber concrete, hiki ke hoʻomaikaʻi i ka hana a me ka lōʻihi o ka palaki, a ua hoʻomaikaʻi maikaʻi ʻia a hoʻohana ʻia ma Shanghai 80,000 mau kahua pāʻani, nā papahana subway a me Oriental Pearl TV Tower. a me nā papahana ʻē aʻe.

I nā makahiki i hala iho nei, ma ʻAmelika Hui Pū ʻIa, Beretania, Iapana a me ʻEulopa Komohana, ua hoʻonui nui ʻia ka pālākiō noi o ka fiber concrete, a ua hoʻohana mua ʻia ka polypropylene fiber concrete i ka ʻenekinia koa ma ʻAmelika Hui Pū ʻIa i ka hopena o 80s o ke kenekulia 20, a a laila ulu koke i ka ʻenekinia kīwila.Mai ke kūlana hou o ka noiʻi haole, ua hoʻonui ʻia ka noiʻi ʻana i ka polypropylene fiber concrete i kekahi ʻano ma ke kumu o ka noiʻi hana kumu.ʻO Sydney Furlan Jr. et al.ua hoʻāʻo ʻia ka ʻoki ʻana ma nā kaola he ʻumikumamāhā, e kuhikuhi ana i ka ikaika ʻako, ka ʻoʻoleʻa (ʻoi loa ma hope o ka wā māwae mua) a me ka paʻakikī ua hoʻomaikaʻi ʻia i ka hoʻohālikelike ʻia me nā kaola paʻa paʻa, a ua aʻo pū i ka hopena o nā stirrups ma nā kaola wiliwili.GD Manolis et al.ua ho'āʻo i ka hopena o ka hopena a me ka haʻalulu manawa o ka moʻo o ka polypropylene fiber concrete slabs me nā ʻokoʻa fiber ʻokoʻa a me nā kūlana kākoʻo like ʻole, a ʻike ʻia ua hoʻonui ʻia ka hopena o ka pale ʻana o ka pā pōhaku ma ka hoʻokomo ʻana i nā fibers me ka hoʻonui ʻana o ka fiber content. akā, ʻaʻohe hopena i ka wā haʻalulu ponoʻī.

ʻO Laizhou Kaihui Machinery Co., Ltd he mea hana ʻoihanalaina hoʻokuʻu ʻana i ka fiber concrete.Welina mai e hoʻokaʻaʻike mai iā mākou no ka ʻike hou aku.
