Hoʻopaʻa paʻa polyurethane, i hana 'ia mai ka polyurethane rubber material, he mau mea ho'ohui i loko o ka nui o na hana 'oihana. Hele mai kēia mau sila i nā ʻano like ʻole, e like me nā O-rings, V-rings, U-rings, Y-rings, rectangular seal, custom-shaped sila, a me nā mea holoi sila.
ʻO ka polyurethane rubber, kahi polymer synthetic, e hoʻopaʻa i ka ʻokoʻa ma waena o ka ʻōpala maoli a me nā plastik maʻamau. Hoʻohana nui ʻia i ka hoʻoili ʻana i ka paʻi metala, ʻo ka polyurethane rubber i nīnau ʻia no ke ʻano hoʻolei polyester. Hoʻohui ʻia ia mai ka adipic acid a me ka ethylene glycol, ka hopena i kahi polymer me ke kaumaha molekala ma kahi o 2000. Hoʻopili hou ʻia kēia polymer e hana i kahi prepolymer me nā hui hope isocyanate. Hoʻohui ʻia ka prepolymer me MOCA (4,4′-methylenebis(2-chloroaniline)) a hoʻolei ʻia i loko o nā mole, a ukali ʻia e ka vulcanization lua e hana i nā huahana polyurethane rubber me nā pae paʻakikī.
Hiki ke hoʻopaʻa ʻia ka paʻakikī o nā sila rubber polyurethane e hoʻokō i nā koi hoʻoili metala kikoʻī, mai ka 20A a i ka 90A ma ka pā paʻakikī Shore.
Nā ʻano hana nui:
- Kūʻē Kūʻē Kūʻē: Hōʻike ka lāʻau polyurethane i ke kūpaʻa kiʻekiʻe loa ma waena o nā ʻano lāʻau āpau. Hōʻike nā hoʻokolohua Laboratory he 3 a 5 mau manawa o kona pale ʻana i ka lāʻau kūlohelohe, me nā noi honua maoli e hōʻike pinepine ana i 10 mau manawa o ka lōʻihi.
- Ka ikaika kiʻekiʻe a me ka elasticity: I loko o ka Shore A60 a i A70 paʻakikī, hōʻike ka polyurethane rubber i ka ikaika kiʻekiʻe a me ka elasticity maikaʻi loa.
- ʻO ka Cushioning Kiʻekiʻe a me ka Hoʻopiʻi Haʻalulu: Ma ka lumi wela, hiki i nā ʻāpana polyurethane rubber ke komo i ka 10% a i ka 20% o ka ikehu vibration, me nā kiʻekiʻe absorption kiʻekiʻe i ka piʻi ʻana o ka vibration frequency.
- ʻO ka ʻaila maikaʻi a me ka pale ʻana i ke kino: Hōʻike ka ʻaila polyurethane i ka liʻiliʻi loa no nā ʻaila mineral non-polar a ʻaʻole i hoʻopilikia ʻia e nā wahie (e like me ke kerosene a me ka ʻaila) a me nā ʻaila mechanical (e like me ka ʻaila hydraulic a me ka lubricating), ʻoi aku ka maikaʻi o nā rubbers kumu nui a me ka nitrile hoʻokūkū. Eia nō naʻe, hōʻike ia i ka pehu nui i nā waiʻona, nā esters, a me nā hydrocarbons aromatic.
- Kiekie Friction Coefficient: ʻOi aku ma luna o 0.5.
- Nā Pono'ē aʻe: Ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi, ka pale ozone, ka pale ʻana i ka radiation, ka pale uila, a me nā waiwai adhesion.
Nā noi:
Hāʻawi ʻia i kona ʻano kino kino a me ka mīkini, hoʻohana pinepine ʻia ka polyurethane rubber i nā noi hana kiʻekiʻe, me nā huahana pale ʻaʻahu, nā mea kūʻai aila ikaika kiʻekiʻe, a me nā mea paʻakikī kiʻekiʻe, modulus kiʻekiʻe. Loaʻa iā ia ka hoʻohana nui ʻana i nā ʻoihana like ʻole:
- Nā Mīkini a me nā Kaʻa: Ka hana ʻana i nā mea hoʻopaʻa braking frequency kiʻekiʻe, nā ʻāpana ʻāpana anti-vibration, nā puna wai, nā hui, a me nā ʻāpana mīkini lole.
- Nā Huahana Paʻi Aila: Ka hana ʻana i nā wili paʻi, nā sila, nā pahu wahie, a me nā sila ʻaila.
- ʻO nā Kaiapuni Kūʻē ʻino: Hoʻohana ʻia i loko o nā paipu conveyor, wili i nā linings, nā pale, nā kānana, nā kapuaʻi kāmaʻa, nā huila friction drive, bushings, brake pads, a me nā kaʻa kaʻa.
- Paʻi anu a me ke kulou: lawelawe ʻana ma ke ʻano he mea hana no ke kaomi anu hou a me nā kaʻina kuʻi, hoʻololi i nā mea make kila e hoʻopau i ka manawa a me ke kumu kūʻai.
- Foam Rubber: Ma ka hoʻohana ʻana i ka hopena o nā hui isocyanate me ka wai e hoʻokuʻu ai i ka CO2, hiki ke hana ʻia ka pahu pahu māmā me nā mea mechanical maikaʻi loa, kūpono no ka insulation, insulation wela, soundproofing, a me nā noi anti-vibration.
- Nā Lapaʻau Lapaʻau: Hoʻohana ʻia i loko o nā ʻāpana ʻōpala hana, nā kīʻaha koko kūlohelohe, ka ʻili synthetic, nā paipu infusion, nā mea hoʻoponopono, a me nā noi niho.
