2.1 Polypropylene faibha kongiri
Kubva mumamiriro ekutsvagisa mumakore achangopfuura, zvinogona kuoneka kuti polypropylene faibha yakasimbiswa kongiri ndiyo yakanyanya kudzidzwa faibha inosimbisa kongiri zvinhu.Tsvagiridzo kumba nekune dzimwe nyika inotarisa pane zvemuviri uye zvemagetsi zvimiro zvefiber kongiri, zvinosanganisira compressive kuramba, kukotama kuramba, kuoma, kusamira, kugadzikana kwemafuta, shrinkage uye kuita kwekuvaka.Zvidzidzo zvakaratidza kuti zvichienzaniswa nebenchmark kongiri, nekuwedzera kwefiber volume ratio (0% ~ 15%), simba rekumanikidza refiber kongiri rinoshanduka zvishoma, simba rekuchinja rinowedzera ne12% ~ 26%, uye kuoma zvakare. inowedzera.Sun Jiaying akadzidza kushanduka kwesimba, brittleness uye kukanganisa kupikisa kwepamusoro-inoita kongiri ine huwandu hwakasiyana hwe polypropylene fiber.Dai Jianguo naHuang Chengkui vakadzidza mhedzisiro yekuedzwa kwekuita kwekuvaka, kumanikidza uye kukotama kuramba, kusimba, kusapinda, kupisa kuchembera kugadzikana uye shrinkage ye mesh polypropylene fiber kongiri.
Panyaya yekushandiswa kwepolypropylene faibha, Zhu Jiang akaongorora nzira isingapinde mvura yepolypropylene faibha kongiri, uye akatanga kuvaka kwekuwedzera polypropylene faibha pauriri hwepasi peGuangzhou New China Building neGuangzhou South Industrial Building.Gu Zhangzhao, Ni Mengxiang nevamwe vakaratidza kuti naironi nepolypropylene faibha kongiri zvine kutsemuka kwakasimba, izvo zvinogona kuvandudza kushanda uye kusimba kwekongiri, uye zvakabudirira kusimudzirwa uye kushandiswa muShanghai 80,000 nhandare yenhandare, mapurojekiti epasi pevhu uye Oriental Pearl TV Tower. nemamwe mapurojekiti.
Mumakore achangopfuura, muUnited States, Britain, Japan neWestern Europe, chiyero chekushandiswa kwefiber kongiri chakawedzera zvishoma nezvishoma, uye polypropylene fiber kongiri yakatanga kushandiswa muinjiniya yemauto muUnited States mukupera kwema80s ezana ramakore rechi20, uye. ipapo yakakurumidza kukura kuva mainjiniya asiri varwi.Kubva pane ichangoburwa mamiriro ekutsvagisa kunze kwenyika, tsvagiridzo yepolypropylene fiber kongiri yakatambanudzwa kusvika kumwero wakati pahwaro hwekutanga kuita tsvagiridzo.Sydney Furlan Mudiki nevamwe.yakaita bvunzo dzeshear pamatanda gumi nemana, zvichiratidza kuti simba rekugera, kuomarara (kunyanya mushure menguva yekutanga yekutsemuka) uye kuomarara kwakavandudzwa kana kuchienzaniswa nematanda ekongiri akajeka, uye akadzidzawo mhedzisiro yekumhanyisa pamatanda ekongiri.GD Manolis et al.akaedza kupikisa kwemaitiro uye nguva yekuzvivhima-vibration yemhando yepolypropylene fiber kongiri slabs ine akasiyana fiber content uye akasiyana anotsigira mamiriro, uye akawana kuti kukanganiswa kwekupikisa kwekongiri slab nekuunzwa kwemafiber zvishoma nezvishoma nekuwedzera kwefiber content, asi zvakange zvisina mhedzisiro panguva yekuzvidedera.
