Kedu ihe bụ PP fiber?

PP eririna-anọchi anya eriri polypropylene, nke bụ eriri sịntetị nke sitere na propylene polymerized.Ọ bụ ihe dị iche iche nwere ngwa dị iche iche na ụlọ ọrụ dịka textiles, ụgbọala, ihe owuwu, na nkwakọ ngwaahịa.N'ihe gbasara ihe owuwu, a na-ejikarị eriri PP eme ihe dị ka ihe nkwado n'ime ihe iji melite njirimara na arụmọrụ ya.Nke a bụ nkọwapụta nke eriri PP:

Njirimara nke PP Fiber:

1. Ike: PP fibers nwere nnukwu ike ike, nke na-enye aka n'ịkwalite ihe na-eme ka ọ dịkwuo ogologo oge na iguzogide mgbawa.
2. Mgbanwe: eriri PP na-agbanwe ma nwee ike ịgwakọta ya ngwa ngwa n'ime ngwakọta ihe na-enweghị emetụta ọrụ nke ihe ahụ.
3. Nguzogide kemịkalụ: Polypropylene na-eguzogide ọtụtụ kemịkalụ, na-eme ka eriri PP dabara adaba maka ojiji na gburugburu ebe siri ike ebe enwere ike kpughee kọnta na ihe na-emebi emebi.
4. Nguzogide mmiri: PP fibers bụ hydrophobic ma ghara ịmịnye mmiri, nke na-enyere aka igbochi mmịpụta mmiri na mmebi nke ihe.
5. Dị fechaa: PP fibers dị fechaa, nke na-eme ka njikwa na ịgwakọta usoro dị mfe n'oge mmepụta ihe.
6. Thermal Stability: PP fibers nwere ezigbo nkwụsi ike na-ekpo ọkụ ma na-echekwa ihe onwunwe ha n'elu oke okpomọkụ.

Ngwa nke PP Fiber na Concrete:

1. Njikwa mgbawa: PP eriri na-enyere aka ịchịkwa plastic shrinkage cracking n'ime ihe site n'ibelata nguzobe na mgbasa nke cracks kpatara ihicha shrinkage.
2. Nguzogide mmetụta: eriri PP na-eme ka nguzogide mmetụta nke ihe dị mma, na-eme ka ọ dị mma maka ngwa ebe ntinye mmetụta bụ nchegbu, dị ka ala ụlọ ọrụ na pavement.
3. Abrasion Resistance: Mgbakwunye nke PP fibers na-eme ka nguzogide abrasion nke ihe dị n'elu, na-agbatị ndụ ọrụ ha na mpaghara okporo ụzọ dị elu.
4. Mmelite nke Ike: PP fibers na-abawanye ike na ductility nke ihe, nke na-eme ka ike ya guzogide ibu dị ike na ike seismic.
5. Shotcrete na Ndozi Mortars: A na-eji eriri PP eme ihe na ngwa shotcrete na ịrụzi ngwa agha iji kwalite arụmọrụ na ịdịte aka ha.
6. Fiber-Reinforced Concrete (FRC): A na-ejikarị eriri PP jikọtara ya na ụdị eriri ndị ọzọ (dịka ọmụmaatụ, eriri igwe) iji mepụta kọmpụta na-eme ka eriri na-arụ ọrụ nke ọma.

Nwụnye na ngwakọta:

• A na-agbakwunye eriri PP na ngwakọta kọmpat mgbe a na-agwakọta ma ọ bụ na-agwakọta, ma n'ụdị kpọrọ nkụ ma ọ bụ gbasasịa na mmiri.
• Usoro onunu ogwu nke PP fiber na-adabere na njirimara arụmọrụ achọrọ nke ihe ahụ ma na-akọwakarị ya site n'aka onye nrụpụta ma ọ bụ injinia.
• Ngwakọta kwesịrị ekwesị dị mkpa iji hụ na nkesa nke eriri ahụ n'otu n'otu n'ime matriks kọmpụta.

Mmechi:

Mgbakwunye PP fiber na-enye ọtụtụ uru na owuwu ihe, gụnyere njikwa mgbape ka mma, nguzogide mmetụta, nguzogide abrasion na ike.Site n'itinye eriri PP n'ime ngwakọta kọmpụta, ndị injinia na ndị ọrụ nkwekọrịta nwere ike ịkwalite arụmọrụ na ogologo ndụ nke ihe owuwu ihe, na-eduga n'ichekwa ọnụ ahịa yana ịba ụba ogologo oge.
