ʻO nā paipu polyurethane he mau paipu ʻoihana kiʻekiʻe i hana ʻia me ka resin polyurethane. Ma muli o kā lākou mau waiwai mechanical maikaʻi loa, ke kūpaʻa corrosion kemika, a me ka hoʻololi ʻana i ke kaiapuni, hoʻohana nui ʻia lākou i nā ʻano ʻano like ʻole. E hoʻolauna ʻia kēia ʻatikala i nā ʻano loea a me ka waiwai kūpono o nā paipu polyurethane mai nā ʻano o nā waiwai waiwai, nā kaʻina hana, nā noi nui, a me nā ʻano hoʻomohala.
I. Nā ʻano waiwai a me nā pono hana
ʻO ka mea nui o nā paipu polyurethane he polyurethane (PU), he mea -molecular kiʻekiʻe i hana ʻia e ka hopena polymerization o nā polyols a me nā isocyanates, e hui pū ana i ka elasticity o ka lāʻau a me ka ikaika o nā plastics. ʻO kāna mau waiwai nui he:
1. Kū'ē Kū'ē kiʻekiʻe:ʻO ka pale abrasion o nā paipu polyurethane he 3-5 mau manawa o ka'ōpala maoli, e kūpono iā lākou no nā hiʻohiʻona kaʻa kaʻa wai me ke kiʻekiʻe kiʻekiʻe a me ka hopena kiʻekiʻe, e like me nā pipeline hydraulic i ka mining a me ka mīkini hana.
2. Ke kū'ē i ka po'e kemika: He kū'ē maika'i ko lākou i ka hapa nui o nā waikawa, nā alkali, nā pa'akai, a me nā mea ho'ohehe'e kino, a pa'a loa lākou i nā kaiapuni ho'okahe -ikaika.
3. ʻO ka ʻoluʻolu a me ka pale ʻana i ka wā: mālama i ka maʻalahi a hiki i nā haʻahaʻa haʻahaʻa (e kū mau ana -40 degere a 80 degere), a hōʻike i ke kūpaʻa o ka wā kahiko o UV i hoʻohālikelike ʻia me nā puʻupuʻu maʻamau.
4. Māmā a me ka ikaika kiʻekiʻe: Me ka mānoanoa 1/8 wale nō o nā paipu kila, hiki iā ia ke pale aku i nā puʻupuʻu o 20-30 MPa, i kūpono ia no nā noi kaumaha.
II. Ke Kaʻina Hana Hana a me ka Hoʻohālikelike ʻenehana Ua hana mua ʻia nā paipu polyurethane me ka hoʻohana ʻana i ka hoʻoheheʻe extrusion, me ke kaʻina kikoʻī e pili ana i ka prepolymerization maka, ka hui ʻana a me ka plasticizing, ka hoʻoheheʻe ʻana, a me ka hoʻoponopono hope. Ma muli o nā ʻokoʻa hoʻolālā, hiki ke hoʻokaʻawale ʻia lākou i ʻelua mau ʻāpana:
1. Nā paipu polyurethane papa hoʻokahi: He kūpono no ka lawe ʻana i ka wai kaomi haʻahaʻa haʻahaʻa, me ke kumu kūʻai haʻahaʻa, akā pale i ka puʻe.
2. Nā paipu polyurethane Composite: Loaʻa i nā hana he nui e like me ke kūpaʻa kiʻekiʻe, ka pale ʻana i ka ʻaʻahu, a me ka pale ʻana i ka waimaka ma o ka ʻaʻahu o loko -lining kūpaʻa, kahi papa hoʻoikaika waena (e like me ke uwea kila a i ʻole ka papa i hoʻopaʻa ʻia i ka fiber), a me kahi papa pale o waho. Hoʻohana maʻamau i nā ʻōnaehana hydraulic pressure -kiʻekiʻe.
Eia hou, ua ho'ololi 'ia kekahi -hose polyurethane kumu kūikawā me nā mea ho'opa'a ahi, nā lā'au antistatic, a me nā mea ho'ohui 'ē a'e no ka ho'okō 'ana i nā kūlana palekana ma nā 'oihana e like me ka petrochemical a me ka eli lanahu.
III. ʻO nā wahi hoʻohana maʻamau ʻo Polyurethane tubing, me kāna mau pono hana holoʻokoʻa, ke pāʻani nei i kahi koʻikoʻi ma nā wahi aʻe:
1. Nā Pūnaehana Hydraulic ʻOihana: Hoʻohana ʻia ma ke ʻano he -paipu ʻaila kiʻekiʻe a i ʻole nā laina pneumatic i ka mīkini ʻenekinia, nā mea hana metala, a me nā laina hana ʻakomi, e pani ana i nā paipu kīpē kuʻuna e hoʻolōʻihi i ke ola lawelawe.
2. Kaʻa Wai: Hoʻohana ʻia i loko o ka ʻoihana kemika, meaʻai, a me nā lāʻau lapaʻau no ka lawe ʻana i nā wai ʻino a i ʻole-maʻemaʻe kiʻekiʻe. Kūlike kona paipu polyurethane maʻemaʻe -maʻemaʻe i nā kūlana FDA a hiki ke hoʻohana ʻia no ka paipu inu a me nā huahana waiu.
3. Kaʻa kaʻa a me ke Kaʻa Kaʻa: Hoʻohana ʻia e like me nā laina wahie, nā laina hoʻoluʻu, a i ʻole nā pili hoʻopili haʻalulu; ʻO kāna mau hiʻohiʻona māmā e kōkua i ka hoʻemi ʻana i ka ikehu.
4. ʻEnekinia Moana: He mea kūpono nā paipu polyurethane hydrolysis -kūpono no ka hoʻopili ʻana i nā mea hana ma lalo o ka wai ma nā moku a me nā paepae o waho, e pale ana i ka ʻinoʻino o ke kai.
IV. Nā ʻano hoʻomohala a me nā pilikia Me ka hoʻomaikaʻi ʻana i ka ʻenehana ʻenehana, ke ulu nei ka paipu polyurethane i ka hana kiʻekiʻe a me nā hana multifunctionality:
• Nā Hoʻomaikaʻi Kaiapuni: Hoʻomohala ʻana i nā kumu waiwai polyurethane ma muli o ka bio no ka hoʻemi ʻana i ka hoʻokuʻu kalapona; ʻoi aku ka maikaʻi o ka hana hou ʻana e hōʻemi i ka pollution ʻōpala.
• Hoʻohui Naʻauao: Hoʻokomo i nā mea ʻike no ka loaʻa ʻana o ka - manawa maoli a me ka nānā ʻana i ka wela, i hoʻohana ʻia ma ke kahua o ka hana akamai.
• Extreme Environment Adaptability: For ultra-high temperature (>120 degere) a i ʻole ka media oxidizing nui, hoʻonui ka ʻenehana nanocomposite i ka palena hoʻomanawanui.
Eia nō naʻe, loaʻa i nā paipu polyurethane nā palena. No ka la'ana, hiki i ka -ho'olaha UV no ka manawa lō'ihi ke ho'opa'a 'ia ka ili, e koi ana i nā pale pale; hiki ke hoʻonui i nā kumukūʻai, pono ke kaulike ma waena o ka hana a me ka hoʻokele waiwai.
Ma ke ʻano he lālā koʻikoʻi o ka paipu ʻoihana hou, nā paipu polyurethane, me ko lākou pale ʻana i ka ʻaʻahu maikaʻi loa, ka pale ʻana i ka corrosion, a me ka maʻalahi, ua lilo ia i mea waiwai nui i koho ʻia i nā kula he nui. I ka wā e hiki mai ana, me ka holomua o ka ʻepekema waiwai a me ka ʻenehana hana, e hoʻonui hou ʻia ka hoʻohana ʻana o nā paipu polyurethane, ʻoiai ʻo ka hoʻomau mau ʻana i ka hoʻomau a me ka naʻauao e hāʻawi i nā hopena maikaʻi loa no ka hana pono o nā ʻōnaehana ʻoihana.
