Nā noi TPU i nā mea pale wai hale

TPU (Thermoplastic Polyurethane)hoʻohana ʻia i ke kūkulu ʻana i ka pale wai ma nā ʻano like ʻole, me nā membrane hanu pale wai, nā pepa pale wai, nā ʻiliʻili hoʻopili wela, a me nā uhi ʻana, e hoʻokō i nā pono pale wai, pale makū, a me ka sila ʻana o nā kūlana like ʻole.

√ Nā Palapala Noi Nui a me nā Laʻana

• Nā Pepa Pale Wai / Membranes: Hoʻohana ʻia ma ke ʻano he mau papa pale wai hana kiʻekiʻe no nā papahana ʻāpana nui e like me nā kaupaku, nā hale lalo, nā tunnels, nā alahaka, a me nā waihona wai.
• Nā Membrane Hanu Pale Wai: E ʻae i ka mahu wai e pakele me ka pale pono ʻana i ke komo ʻana o ka wai wai o waho - kūpono no ka ʻaoʻao o waho o nā papa insulation e hoʻoikaika i ka ea ea o ka hale, hoʻohana ʻia no nā paia, nā kaupaku, a me nā hale lāʻau.
• Nā Mea Sila Pale Wai: Hoʻohana ʻia no nā hono, nā lihi o ka pā, nā aʻa paipu a me nā kikoʻī ʻē aʻe, a i ʻole he mau mea sila hiki ke pehu i ka wai no nā hono hoʻonui a me ke kūkulu ʻana.
• Nā Uhi Pale Wai: Hoʻopili ʻia ma ke ʻano he uhi ma luna o ka sima, ka metala, a me nā mea ʻē aʻe e hana i kahi ʻili pale wai humuhumu ʻole - kūpono no nā loko wai, nā papahele ʻoihana, a pēlā aku.
• Aniani Palekana Laminated: Hoʻopaʻa pono ka ʻili TPU ikaika a paʻa i nā ʻāpana aniani e pale ai i ka haki ʻana - hoʻohana ʻia i nā paia pale kiʻekiʻe a me nā kukui lani.

√ Nā Kūlana ʻenehana maʻamau a me ka hana

• Nā Waiwai Kino/Mīkini:
  ʻO ka ikaika tensile o nā pepa pale wai he 30–45 MPa maʻamau, elongation i ka haki ʻana he 500–700%, a me ka mānoanoa he 0.2–0.5 mm.
  ʻO ke kūpaʻa o nā lole TPU hui pū ʻia he ≥80 N/mm² a me ka elongation i ka haki ≥300%.
• Ka Paʻa a me ke Kūpaʻa:
  Wahi heheʻe ma kahi o 90°C, mahana hoʻololi wela 70–90°C.
  Ma hope o 500 mau hola o ka ʻelemakule wela ma 80°C, ʻo ka pohō o ka ikaika tensile <5%.
  Hana paʻa ma -40°C; hiki ke hoʻohana ʻia kekahi mau papa a hiki i -65°C.
• Kaiapuni a me ka Palekana:
  ʻAʻohe mea ʻawahia, ʻaʻohe ala, a aloha i ke kaiapuni ka TPU.
  ʻO ke ʻano pauka paʻa 100% hāʻawi i ka ʻole o nā hoʻokuʻu VOC, e hoʻokō ana i nā koi kūkulu ʻōmaʻomaʻo.

√ Nā kiko hana kūkulu a me ka hoʻohana

• Nā Hana Hoʻohuihui: No ka laʻana, ʻo ke kāwili ʻana i ka 69.2% TPU, 30% pauka laholio, a me ka 0.8% defoamer hiki ke hana i nā mea wai ʻole hana kūpono no ke kumukūʻai no nā papa sila wai ʻole o ke kaʻaahi wikiwiki.
• Koho Hana:
  • Pauka TPU: uhi hoʻopuehu + kaomi wela
  • ʻO ke kiʻiʻoniʻoni hoʻoheheʻe wela TPU: kuʻi alapine kiʻekiʻe a i ʻole ka ultrasonic
  • Pepa TPU: ka hoʻoheheʻe ʻana i ka ea wela a i ʻole nā ​​​​mea hoʻopili kūikawā no ka uhi ʻana
• He mea koʻikoʻi ke kūpaʻa wela: He mea nui ke kūpaʻa wai no ka pale wai o ke kūkulu ʻana. Hoʻohaumia nui kekahi mau ʻano TPU i ka wai wela no ka manawa lōʻihi; hiki i ka makū kiʻekiʻe ke hoʻoulu i ka hydrolysis e alakaʻi ai i ka hāʻule ʻana o ka sila. No laila, he mea nui loa ke koho ʻana i kahi papa kūpaʻa hydrolysis.
• He mea nui ka mālama ʻana i ka ʻili: Ma nā substrates porous a laumania paha, ʻo ka hoʻohana ʻana i kahi primer kūpono e hoʻomaikaʻi nui i ka hoʻopili ʻana ma waena o ka uhi TPU a me ka substrate, e hōʻoiaʻiʻo ana i ka kūpaʻa holoʻokoʻa o ka papa pale wai.

• No ke kūkulu ʻana i nā hale me ka pale wai,TPU i hoʻokumu ʻia i ka polyetheri hana ʻia eYantai Linghua mea houʻo ia ke koho maikaʻi loa no ka mea ʻo kona mau pilina ether (-COC-) e hāʻawi i ke kūpaʻa hydrolysis ikaika a ʻoi aku ka kūpono no nā wahi pulu no ka manawa lōʻihi.
