ʻO nā ʻāpana Polyurethane Extruded

ʻO nā ʻāpana extruded polyurethane he mau mea waiwai i hana ʻia mai ka resin polyurethane ma ke ʻano he mea matrix a hana ʻia ma o ka ʻenehana extrusion. Aia kāna hiʻohiʻona nui i ka hui pū ʻana o ka hana maikaʻi loa o ka polyurethane a me ka hana kiʻekiʻe o ka ʻenehana extrusion, i hoʻohana nui ʻia i nā kula e like me ke kūkulu ʻana, ka lawe ʻana, a me nā mīkini.

1. Mechanical waiwai

• Ka ikaika kiʻekiʻe: ʻO ka ikaika tensile ma mua o 50MPa, a hiki i ka ikaika kulou ke hiki i 50-75MPa, hiki ke hoʻololi i nā mea kila a me nā alumini.
• Māmā: me ka haʻahaʻa haʻahaʻa ma mua o ke kila a me nā alumini alumini, ʻoi aku ka haʻahaʻa o ka halihali a me nā kumukūʻai hoʻonohonoho. ?

2.Corrosion kū'ē

• Acid alkali paʻakai: hiki ke pale aku i ka nui o ka waikawa, ka alkali, ka paʻakai a me ka ʻino kūlohelohe, kūpono i nā kaiapuni a me ka wai.
• ʻO kaʻaila kū'ē: He kū'ē maikaʻi kona i nāʻaila likeʻole a kūpono i nā sila e like me nā silaʻaila. ?

3.Insulation a me ka thermal insulation hana

• ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa: ʻO 0.22W / m • k wale nō ka wela wela ma ka lumi wela, kahi e pili ana i ka 1/700 o ka alumini alumini a kūpono i nā mea insulation.
• Ka helu haʻahaʻa o ka hoʻonui wela laina: E like me nā mea pā, ʻaʻole maʻalahi ka hana ʻana i nā āpau ke loli ka ʻokoʻa wela. ?

4.Production kaʻina hana

• Pono: Hiki i ka wikiwiki extrusion ke piʻi i ka 0.6-2.0m / min, ʻo ia ka 2-5 mau manawa ʻoi aku ka maikaʻi ma mua o nā mea hana kuʻuna.
• Palekana Kaiapuni: He solvent-ka kaʻina hana a hoʻokō i nā koi o ka hana ʻōmaʻomaʻo. ?

5.Application scenario

• Hoʻolālā: Hoʻohana ʻia no nā ʻāpana e like me nā puka a me nā puka makani, nā pā pale, a me nā mea ʻē aʻe, e hoʻemi i ke kaumaha o nā hale a hoʻomaikaʻi i ka hana ʻana i ke kani. ?
• Kaʻahele: Ka hana ʻana i nā ʻāpana kaʻa a me nā moku e hōʻemi i ke kaumaha o ke kino a hoʻonui i ke ola lawelawe.
• Infrastructure: Hoʻohana ʻia no ke kākoʻo ʻana i nā ʻāpana o nā alahaka a me nā tunnels e hoʻomaikaʻi ai i ka lōʻihi o ke kūkulu ʻana.

ʻO ka Polyurethane (PU no ka pōkole) he ʻano o ka plastic polyurethane i loaʻa nā waiwai pono he nui, e like me ka elasticity, transparency, oil resistance, grease resistance, a me ke pale ʻaʻahu. ʻO ka ʻōlelo ʻenehana, he mau elastomers thermoplastic i haku ʻia me nā copolymers block linear o nā ʻāpana paʻakikī a palupalu.

Loaʻa i kā mākou huahana ka maikaʻi maikaʻi, hana kiʻekiʻe, a me nā kumukūʻai kūpono. Hiki iā mākou ke hana a hana i nā ʻāpana i hoʻoheheʻe ʻia ʻo PU e like me nā kiʻi a nā mea kūʻai aku.

1. Ho'ohana 'ia no ka 'oihana 'oihana pale lole ki'eki'e, ki'eki'e -sealing pressure a me nā huahana lā'au lapa'au, e like me ka hydraulic cylinder sealing.

2. Loaʻa nā mea like ʻole a me ka paʻakikī iā ʻoe e koho mai. Hiki iā ʻoe ke hāʻawi iā mākou i nā laʻana a i ʻole nā ​​kiʻi, a hāʻawi mākou iā ʻoe i nā huahana maikaʻi loa.

Nā huahana pale: polyurethane extruded 'āpana, China polyurethane extruded 'āpana mea hana, mea hoʻolako, hale hana
