Mutengo wepamusoro we2021 Polypropylene Crude Fiber - Polypropylene Fiber Micro Polypropylene Fiber Reinforced Concrete Fibers PPF Micro Fibers – Kehui

Polypropylene fiber (PPF) imhando yezvinhu zvepolymer zvine huremu hwakareruka, simba rakawanda, uye kuramba ngura. Kuramba kwekongiri kunogona kuvandudzwa nekuwedzera polypropylene fibers. PPF inogona kuwedzera kupararira kwepore size yekongiri. Nekuda kweizvozvo, kugara kwenguva refu kwekongiri kunowedzerwa zvakanyanya sezvo PPF inogona kuvharira kupinda kwemvura kana ma ions anokuvadza mukongiri. Kusiyana kwefiber content, fiber diameter, uye fiber hybrid ratio zvichave nemigumisiro yakasiyana pa durability indexes. Hunhu hwe durability hwekongiri hunogona kuvandudzwa zvakanyanya nekubatanidza PPFs nesimbi fibers. Zvikanganiso zvePPF mukushandiswa mukongiri ndiko kupararira kusina kukwana mukongiri uye kusasimba kwekubatana necement matrix. Nzira dzekukunda zvikanganiso izvi ndeyekushandisa fiber yakagadziriswa ne nanoactive powder kana chemical treatment.

Fiber iyi inodzivirira kutsemuka kwesimbi ifiber ine simba guru inoshandisa polypropylene yefiber sezvinhu zvakabikwa uye inogadziriswa nenzira yakakosha. Iine simba guru rekudzivirira acid, simba guru rekudzivirira alkali, simba shoma rekupisa, uye makemikari akasimba. Kuwedzera simbi kana kongiri kunogona kudzora zvinobudirira kuputika kunokonzerwa nekuchinja kwekushisa muchikamu chekutanga chekupwanya simbi nekongiri, kudzivirira nekudzivisa kuumbwa nekukura kwezvimedu, uye kuvandudza zvikuru simba rekudzivirira kutsemuka kwesimbi, kusapinda mvura, simba rekudzivirira kukanganiswa uye kudengenyeka kwenyika. Kudzivirira kudengenyeka kwenyika kunogona kushandiswa zvakanyanya muinjiniya yepasi pevhu kudzivirira mvura, matenga, madziro, pasi, madziva, makamuri epasi, migwagwa nemabhiriji mumapurojekiti ekuvaka eindasitiri neehurumende. Chinhu chitsva chakanakira simbi nekongiri ine simba rekudzivirira kutsemuka, kudzivirira kunyura kwemvura uye kukwesha.

Zviyero zvemuviri:
Rudzi rweFiber: Bundle Monofilament / Density: 0.91g/cm3
Dhayamita yakaenzana: 18~48 μm / kureba: 3, 6, 9, 12, 15, 54mm, inogona kuchekwa zvisina kufanira zvichienderana nezvinodiwa nemushandisi.

Nzvimbo yekunyunguduka: 160～180℃ / Nzvimbo yekubatidza: 580℃

Mabasa Makuru:
Sechinhu chechipiri chinotsigira kongiri, polypropylene fiber inogona kuvandudza zvikuru kusimba kwayo kutsemuka, kusapinda mvura, kusarova, kusabatwa nemhepo, kusadonha kwemvura, kusaputika, kusachembera uye kushanda, kusapomba mvura, uye kuchengetedza mvura.
● Kudzivirira kugadzirwa kwematombo ekongiri
● Kuvandudza kupindirana kwekongiri nekudzivirira kupinda kwemvura
● Kuvandudza kusimba kwekongiri pakunyunguduka kwechando
● Kuvandudza kusimba kwesimba rekongiri, kusimba kwesimba rekongiri, kusimba kwesimba rekongiri uye kushanda kwesimba rekongiri
● Kuvandudza kugara kwenguva refu uye kuramba kukwegura kwekongiri
● Kuvandudza kusimba kwekongiri pamoto

Nzvimbo dzeKushandisa:
Chimiro chakasimba chekongiri chisingapindi mvura:
Uriri hwepasi pevhu, madziro eparutivi, denga, slab yakagadzirwa panzvimbo yedenga, dziva, nezvimwewo. Mainjiniya, mapurojekiti ekuchengetedza mvura, nzira dzepasi pevhu, nzira dzendege, nzvimbo dzechiteshi, madhiri epamusoro penzira dzinopfuura nepakati, mapiers, zvivakwa zvakareba zvikuru zvine zvinodiwa zvakanyanya kuti zvisatsvedzerere, zvisatsvedzerere, uye zvisatsvedzerere.

Dura resimende:
Kupenda madziro mukati (kunze), kupurasita nekongiri ine mhepo, putty yekushongedza mukati uye thermal insulation mortar.
Injiniya inodzivirira kuputika uye inodzivirira moto:
Mapurojekiti emauto ekudzivirira mhepo, mapuratifomu emafuta, machimuni, zvinhu zvinodzivirira, nezvimwewo.

Shotcrete:
Mugero, madziro emugero, chimiro chine madziro matete, kusimbisa materu, nezvimwewo.
Mirayiridzo yekushandisa
Chipimo chinokurudzirwa:
Huwandu hunokurudzirwa hwedhaka pa sikweya imwe neimwe yedhaka replastering rakajairika i0.9 ～1.2kg
Huwandu hunokurudzirwa hwesimbi yekupisa patani: 1 ～3kg
Huwandu hwekongiri hunokurudzirwa pa cubic meter yekongiri ndeinotevera: 0.6 ~ 1.8kg (sekureva)

Tekinoroji yekuvaka uye matanho
①Zvichienderana nehuwandu hwekongiri yakasanganiswa nguva imwe neimwe, huremu hwefaibha inowedzerwa nguva imwe neimwe hunoyerwa nemazvo zvichienderana nezvinodiwa nechiyero chemusanganiswa (kana huwandu hunokurudzirwa hwekusanganisa).
② Mushure mekugadzirira jecha nejecha, wedzera fiber. Zvinokurudzirwa kushandisa muchina wekusanganisa. Wedzera aggregate pamwe chete nefiber mumuchina wekusanganisa, asi chenjerera kuti uve nechokwadi chekuti fiber yawedzerwa pakati pe aggregate woisanganisa yakaoma kwemasekondi angangoita makumi matatu. Mushure mekuwedzera mvura, sanganisa yakanyorova kwemasekondi angangoita makumi matatu kuti uparadzire fiber zvizere.
③ Torai mienzaniso nekukasika mushure mekusanganisa. Kana shinda dzacho dzakasanganiswa zvakaenzana kuita monofilaments, kongiri inogona kushandiswa. Kana kuchine shinda dzakasanganiswa, wedzerai nguva yekusanganisa nemasekonzi makumi maviri kusvika makumi matatu musati mashandisa.
④ Maitiro ekuvaka nekuchengetedza kongiri yakawedzerwa fiber akafanana chaizvo neaya ekongiri yakajairika. Yagadzirira kushandiswa.
