Hoʻopau ʻili i hoʻonui ʻia: Hiki i nā mea hoʻohui e like me nā mea hoʻokomo i ka ea ke hoʻomaikaʻi i ka hoʻopau ʻana a me ke ʻano o ke koneki ma o ka pale ʻana i nā hemahema e like me ka haki ʻana., honeycombing, aiʻole ka lepo lepo, hōʻoiaʻiʻo i ka maʻalahi, ili ʻoihana.

ʻO ke kikoʻī o nā pulupulu hana ʻo PVA Fiber i hoʻopaʻa ʻia i hoʻopaʻa ʻia i ka hoʻohui ʻana i ka ʻili ʻāʻī no ka UHPC.

ʻO ka pulupulu PVA hana no ka hana kiʻekiʻe

Ikaika, Manaʻo ʻia ʻo Fracture Control no UHPC a ma o aku

pulupulu PVA synthetic he mea hoʻohui kiʻekiʻe i hana ʻia mai ka waiʻona polyvinyl. Hana ʻia ia no ka hoʻoikaika ʻana i ke kaʻa a hōʻemi i ka haki ʻana. Hoʻohana maikaʻi kēia fiber i loko o ke koʻikoʻi ultra-high-performance (UHPC), pana pana, nā mea hana mua, a me nā noi ʻē aʻe e pono ai.

Nui nā fiber, laha like, a hoʻopaʻa paʻa me ka matrix sima. Kōkua kēia paʻa paʻa i ka hoʻoponopono ʻana i nā ʻokiʻoki i ʻike pinepine ʻia i ka wā mālama. Hoʻonui ia i ka hopena a me ka lōʻihi. ʻAʻole like me nā kaula kila, ʻAʻole ʻino nā pulu PVA. Kūpaʻa lākou i ka manawa a mālama i ka maʻemaʻe a me ka maʻemaʻe.

He lōʻihi mau a me ke anawaena o kēlā me kēia fiber. Hāʻawi kēia ʻano ʻaʻahu i ka hāʻawi like ʻana i ka wā i hui ʻia i loko o ke koneki. ʻOi aku ka maikaʻi o ka hana a me ka liʻiliʻi o nā puʻupuʻu. He mea maʻalahi loa ka hoʻonoho ʻana a me ka hoʻopau ʻana i nā wahi i luna me ka ʻole o ka manaʻo.

pulupulu PVA hoʻonui i ka flexural stamina a me ka mana absorption. E ʻoi aku ka ikaika o nā frameworks ma lalo o ka hopohopo, haʻalulu, a i ʻole nā ​​ukana i manaʻo ʻole ʻia. He kūpono kēia no nā papahele, alahaka, tunnels, and industrial slabs where long-lasting efficiency matters.

The item satisfies worldwide criteria for synthetic fibers in concrete. It is compatible with the majority of concrete kinds and common admixtures like superplasticizers. ʻAʻole pono nā mea hana kūikawā– simply include it throughout normal batching.

Because it is non-corrosive and alkali-resistant, pulupulu PVA maintains its residential properties in rough environments. It sustains sustainable building by expanding life span and decreasing upkeep needs.

Use this fiber to build much safer, longer-lasting concrete structures with fewer noticeable fractures and less repair in time.

Applications of Synthetic Fibers Plastic Synthetic PVA Fiber Reinforced Concrete Admixture Anti Crack Fiber for UHPC

Increase Concrete Performance with PVA Synthetic Fibers

ʻOi aku ka mana, Tougher, Crack-Resistant Concrete

PVA (waiʻona polyvinyl) artificial fibers are a clever option for modern concrete mixes. These tiny fibers mix evenly right into the concrete. They aid hold the material with each other when stress and anxiety or motion takes place. This considerably reduces splitting from shrinking, loli ka pae wela, or impact.

Contractors utilize PVA fibers in ultra-high-performance concrete (UHPC) and other sophisticated mixes. The fibers imitate interior reinforcement. They connect micro-cracks prior to they become larger troubles. This means longer life for frameworks like bridges, pauku, papahele, a me nā mea hana mua.

ʻAʻole like me nā kaula kila, ʻAʻole ʻino nā pulu PVA. They stay steady inside concrete for years. They additionally do not clump throughout blending. This gives a smooth, constant set each time. Specialists locate them easy to work with– no unique devices or actions are needed.

The fibers improve flexural toughness and durability. Hiki i ka palaki me ka PVA ke wili iki me ka poino ole. Hoʻonui ia i ka ikehu i ka wā i manaʻo ʻole ʻia. ʻO ia ka mea e ʻoi aku ka palekana ma nā wahi ʻōlaʻi a i ʻole nā ​​​​wahi kaʻa nui.

ʻO nā mea hoʻohui PVA fiber e hoʻokō i nā koi o ka ʻāpana koʻikoʻi. Nānā ʻia lākou no ka paʻakikī, paa paa, a me ka launa pū me ka sima. Hiki iā ʻoe ke hoʻohui pololei iā lākou ma ka hale batching a i ʻole ma ka pūnaewele. He haʻahaʻa ka nui o ka dosage– maʻamau maʻalahi 0.5% i 2% ma ka nui o ke koneki.

Hoʻemi kēia lawelawe i nā kumukūʻai hoʻoponopono a hoʻonui i ke ola. Kākoʻo ʻo ia i nā ʻāpana lahilahi a me nā hoʻolālā māmā. Koho nā mea hoʻolālā a me nā mea hoʻolālā i nā fibers PVA i ka wā e pono ai ka pono.

Nā pōmaikaʻi nui: .
– Haʻalele i ka wā ʻōpio a me ka haʻihaʻi lōʻihi.
– Hoʻonui i ka hopena a me ke kūpaʻa luhi.
– Hana maikaʻi ma UHPC, pana pana, a me ka hoʻopaʻa paʻa ponoʻī.
– Non-corrosive a me ka alkali-kue.
– Maʻalahi e hoʻohui a hui.

E hoʻohana i nā fiber synthetic PVA e hoʻomohala maʻalahi, ikaika aku, a me nā hale paʻa i hilinaʻi nui ʻia.

ʻO ka moʻolelo o ka hui

ʻO mākou ke alakaʻi o ka honua i nā ʻenehana māmā a me nā hoʻonā ʻenehana i hana ʻia. ʻIke ʻia ma ka honua holoʻokoʻa no kāna kūpaʻa i ka noiʻi, mea hou, a me ka ʻike noiʻi, ke hāʻawi nei mākou i nā hoʻonā ʻenehana i hana ʻia mai ka makahiki 2012.

Hiki iā mākou ke hāʻawi aku i ka hoʻohui ʻana i nā mea hoʻohui kiʻekiʻe kiʻekiʻe a me nā huahana pili i ka foam concrete a puni ka honua.

He keʻena ʻenehana ʻoihana a me ka ʻoihana kiaʻi maikaʻi ka hui, he hale hana i hoolako pono ia, a hoʻolako ʻia me nā lako hoʻāʻo kiʻekiʻe a me ke kikowaena lawelawe mea kūʻai aku ma hope o ke kūʻai aku.

5 Nā nīnau nīnau no nā pulupulu hana ʻo PVA Fiber i hoʻopaʻa ʻia i hoʻopaʻa ʻia i ka hui pū ʻana i ka pulupulu anti crack no UHPC.

Nā nīnau i nīnau pinepine ʻia e pili ana i ka fiber PVA no ka paʻa

He aha ka PVA fiber i hoʻohana ʻia no ka ʻuala?

PVA (waiʻona polyvinyl) hoʻohui ʻia ka fiber i ke kaʻa e hōʻemi ai i ka haki ʻana. Hana maikaʻi ʻo ia i ka ʻulaʻula ultra-high-performance (UHPC). Kōkua nā fiber i ka mālama ʻana i ka emi ʻana a hoʻomaikaʻi i ka paʻakikī. Hoʻoikaika kēia i ka huahana hope a ʻoi aku ka lōʻihi.

Pehea e pale ai ka fiber PVA i nā māwae?

Ke maloʻo ka lāʻau, emi a hiki ke pohā. Hoʻolaha like nā pulu PVA ma o ka hui ʻana. Hoʻopaʻa pū lākou i ka mea i ka wā e ulu ai ke kaumaha. Hoʻopau kēia i nā māwae liʻiliʻi mai ka ulu ʻana i mau māwae nui. He maʻalahi ka hopena, ʻoi aku ka paʻa o ka ʻili.

ʻOi aku ka maikaʻi o ka fiber PVA ma mua o nā fiber synthetic ʻē aʻe?

He paʻa ikaika ka PVA fiber me ka paʻi sima. Kūʻē ia i ka alkali a ʻaʻole e hoʻohaʻahaʻa i ka ʻeke. Hoʻohālikelike ʻia me ka polypropylene a i ʻole nylon, Hāʻawi ka PVA i ka ikaika tensile maikaʻi a me ka ductility. ʻO ia ke kumu i koho pinepine ʻia ai no nā noi kiʻekiʻe e like me UHPC.

ʻEhia ka nui o ka fiber PVA e hoʻohui ʻia i ke kaʻa?

ʻO ka dosage maʻamau mai 0.5% i 2.0% ma ka leo o ka hui nui. ʻO ka nui pololei e pili ana i ka pono o ka papahana. ʻOi aku ka nui o ka hoʻouku ʻana i ka paʻakai akā hiki ke hoʻopilikia i ka hana. E hahai mau i nā kuhikuhi a ka mea hana no nā hopena maikaʻi loa.

Hiki ke hui pū ʻia ka fiber PVA me nā mea hoʻohui ʻē aʻe?

ʻAe. Hana maikaʻi ʻia ka fiber PVA me nā mea hoʻohui paʻa maʻamau e like me nā superplasticizers, uahu silika, aiʻole lehu lele. E hoʻopaʻa pono i ke kaʻina hui ʻana. ʻO ka hoʻopuehu kūpono e pale i ka clumping a e hōʻoia i ka hana ʻana i loko o ke kaʻa.
