ʻEhia kou ʻike e pili ana i nā kaula polyurethane? (Uea TPU)

Uea PolyurethanePili ʻo s i nā kaula e hoʻohana ana i nā mea polyurethane ma ke ʻano he insulation a sheath paha. ʻO ko lākou kūpaʻa super wear e pili ana i ke kūpaʻa super wear o ka sheath uwea a me ka papa insulation.

 

ʻO ka mea polyurethane i hoʻohana ʻia i nā kaula i kapa ʻia ʻo TPU, ʻo ia hoʻi ka thermoplastic polyurethane elastomer rubber. Ua māhele nui ʻia i ke ʻano polyester a me ke ʻano polyether, me ka pae paʻakikī (60HA-85HD), kūpaʻa i ke kapa, kūpaʻa i ka ʻaila, moakaka a me ka elastic. ʻAʻole wale ka TPU i loaʻa i nā waiwai kūpaʻa kiʻekiʻe maikaʻi loa, ke kūpaʻa kiʻekiʻe, ke kūpaʻa kiʻekiʻe, ikaika a me ka pale ʻelemakule, akā he mea aloha kaiapuni makua hoʻi.

 

I kēia lā, e alakaʻi ʻo Lansheng Cable iā ʻoe ma o nā hiʻohiʻona nui 8 a me nā wahi hoʻohana o ke kaula polyurethane.

 

8 mau hiʻohiʻona nui：

1. Ke kū'ē ʻana i ke kapa komo

 

Ke hoʻokomo pinepine ʻia ke kaula i nā hana mechanical e like me ka friction, ka ʻūlū ʻana a me ka wili ʻana i ka wā e hoʻohana ai, e hoʻoulu ai i kona ʻili e ʻaʻahu mālie, no laila he mea nui loa ka hiki ke koho ʻia o nā mea.

 

Loaʻa i nā mea maka plastik TPU ke kūpaʻa maikaʻi loa i ka ʻaʻahu ʻana a ʻoi aku ma mua o ʻelima mau manawa ke kūpaʻa i ka ʻaʻahu ma mua o nā kaula i uhi ʻia i ka laholio maoli. ʻO lākou kekahi o nā mea koho mua no nā huahana kūpaʻa i ka ʻaʻahu.

 

2. Hana tensile

 

ʻO ka ikaika tensile o nā kaula polyurethane a hiki i ka 38MPa, a ʻo ka ikaika tensile o nā kaula lima rapa maʻamau (kekahi o nā kaula maʻamau ma ka mākeke) he 8-12MPa wale nō.

 

Ke hoʻohana ʻia ke kaula i loko o kahi ʻano me ka hoʻoikaika ʻia ʻana o ka traction, he hopena tensile maikaʻi ʻole ka uhi kaula i uhi ʻia i ka rapa, a maʻalahi ka haki ʻana o ke kumu ma hope o ke kau ʻia ʻana i ka tensile o waho. ʻO ke kūpaʻa tensile maikaʻi loa o ka uhi kaula polyurethane a me ka insulation e pāʻani i kahi hana pale maikaʻi ma ke kumu uea, e hoʻomau a paʻa.

 

3. Hana haehae

 

ʻO ka ikaika haehae ka hiki o ka mea ke kū'ē i ka haehae. Ma keʻano laulā, he kiʻekiʻe ke kūpaʻa o ka TPU i ka haehae, a he maikaʻi loa ka ikaika haehae i hoʻohālikelikeʻia me kekahi mau laholio a me ka palakiko i hoʻohana pinepineʻia.

 

4. Hana wili

 

He nui nā kaula palaki (e like me RVV) e haki ma lalo o nā pilikia pinepine. Hiki i nā kaula polyurethane ke mālama i ke kūpaʻa kūlou maikaʻi loa ma lalo o nā ʻano like ʻole, e lilo ana lākou i kekahi o nā koho maikaʻi loa no nā ʻano kūlou pinepine.

 

5. Ke kū'ē'ē hydrolysis

 

He maikaʻi ke kūpaʻa wai o nā kaula polyurethane ma lalo o ka turbidity, a ʻaʻole e ʻike i ka hydrolysis maopopo i loko o 1 a 2 mau makahiki, ʻoi aku ka maikaʻi o ka moʻo polyether.

 

6. Ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa ʻokikene

 

Ma keʻano laulā, hiki ke hoʻopau maʻalahi ʻia nā mea maka plastik i kahi kaiapuni ma luna o 70 ℃ no ka manawa lōʻihi, a he maikaʻi ka hiki ke antioxidant o TPU; ma keʻano laulā, hiki i ke kū'ē ʻana o ka mahana TPU ke hiki i 120 ℃.

 

7. Ke kū'ē'ē'ana o ka'aila a me nā waiwai kū'ē'ē lā'au

 

He mea polymer polar kiʻekiʻe ka TPU me ka liʻiliʻi o ka pilina me nā aila mineral non-polar a aneane ʻaʻole pala i nā aila wahie (e like me kerosene, gasoline) a me nā aila mechanical (e like me ka aila hydraulic, ka aila mīkini, ka aila lubricating, a me nā mea ʻē aʻe); i waena o lākou, ʻoi aku ka maikaʻi o nā huahana polyester series i nā kaula polyurethane.

 

8. Hana mahana haʻahaʻa

 

He maikaʻi loa ke kūpaʻa ʻana o nā kaula polyurethane i ka mahana haʻahaʻa a hiki pinepine i ka -50℃. Hiki iā lākou ke pani i nā ʻano like ʻole kahi hiki ʻole ke hoʻohana ʻia nā kaula PVC a me nā kaula lima laholio ma muli o ka brittlement wela haʻahaʻa. He kūpono loa lākou no nā kaula i hoʻohana ʻia ma nā wahi anuanu loa.

01Uea noi moana

 

Hiki ke hoʻokaʻawale maʻalahi ʻia nā ʻano o nā kaula moana mai nā ʻano ʻehā.

 

Mai kahi hiʻohiʻona hoʻonohonoho, ua māhele nui ʻia i nā kaula submarine ʻekolu-core a me nā kaula submarine hoʻokahi-core. Hoʻohana nā laina voltage waena a me ka haʻahaʻa i nā kaula submarine ʻekolu-core, a hoʻohana nā laina voltage kiʻekiʻe i nā kaula submarine hoʻokahi-core; mai kahi hiʻohiʻona hana, hapalua kenekulia i hala aku nei, he hana hoʻoili mana maʻalahi wale nō nā kaula submarine. I kēia manawa, hoʻohui nā kaula submarine i ʻelua mau hana, e hoʻokō pono ana i ka hoʻoili ʻana o ka uila a me nā hōʻailona ma ka laina kaula like; mai ka hiʻohiʻona o ka hoʻohuihui insulation, ua māhele ʻia lākou i nā kaula submarine insulated i hoʻopiha ʻia me ka ʻaila a me nā kaula submarine insulated plastic extruded; mai ka hiʻohiʻona o ke ʻano ukana, ua māhele ʻia lākou i nā kaula submarine DC a me nā kaula submarine AC. ʻO nā ʻano o nā kaula submarine DC he mau pohō liʻiliʻi a maʻalahi hoʻi e hoʻokō i ka hoʻoili mamao loa, akā ʻaʻole waiwai ka ʻike noi o nā kaula submarine DC. Kiʻekiʻe ke kumukūʻai kūkulu kākoʻo o nā kikowaena hoʻololi DC, a nui nā kaula submarine AC, akā ua oʻo ka ʻenehana hana a me ka mālama ʻana a he liʻiliʻi ke kumukūʻai kūkulu kākoʻo. No laila, pono nā mea hoʻolālā laina kaula submarine e hana i nā kālepa loea a me ka hoʻokele waiwai e hoʻonui i nā pono.

02  Nā lopako ʻoihana a me nā Uea Lopakonā

 

Ua hoʻomaopopo ʻia ua hoʻokomo ʻia ma Kina ma mua o ka hapalua o nā robots ʻoihana hou o ka honua, a ʻo nā robots i hana ʻia ma Kina kekahi hapa nui. Ma ke ʻano he mau ʻāpana e kūlike me nā robots, ʻaʻole hiki ke hoʻohaʻahaʻa ʻia ke koi no ka hoʻomohala ʻana i ke kaula robot. Ke ulu nui nei ka ʻoihana robot ʻoihana ma Kina a ke huki nei hoʻi i ka hoihoi mai nā ʻoihana kaula. Ma ke ʻano he ʻāpana koʻikoʻi o nā robots, Uea a me ke kaula ua hōʻike i ka ulu nui ʻana o ke koi mākeke, a e hoʻolauna mai nā ʻoihana uea a me ke kaula i kahi manawa kūpono no ka hoʻomohala ʻana a me ka hoʻololi ʻana.

03 Mīkini awa a me ke kaula wili gantry crane

 

Pono ke kaula wili gantry crane e hiki ke hoʻopuni aunoa i ke kaula, a ʻaʻole pono ka torque hoʻokele o ka wili kaula e emi ma mua o ka torque hoʻopuni kiʻekiʻe loa e pono ai i ka wā e hoʻopuni ai i ke kaula. I ke kaʻina hana hoʻokuʻu kaula, pono e liʻiliʻi ka ikaika traction e hana ana ma ke alakaʻi kaula. No nā kaula me ka ʻole o kahi ʻiʻo i hoʻoikaika ʻia, ʻo ka ikaika tension kiʻekiʻe loa e hana ana ma ka ʻāpana keʻa o ke alakaʻi keleawe he 20N/mm². No ka wikiwiki o ka wili ʻana o ke kaula i koi ʻia a i ʻole ke kaumaha o ke kaula, pono e hoʻohui ʻia kahi kaula uea kila i hoʻoikaika ʻia e hiki ke kū i ka ikaika traction i koi ʻia ma ke ʻano he ʻiʻo.

04Nā kaula mīkini ʻenekinia mining

 

Pono nā uea a me nā kaula o nā mīkini ʻenekinia mining i ke kūpaʻa ʻoi aku ka maikaʻi o ka ʻaʻahu, ke kūpaʻa hydrolysis, ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa oxidation, no laila he paʻakikī hoʻi nā koi no nā mea uea a me nā kaula.
