Hoohana Huahana
ʻO HQEE kahi mea hoʻonui kaulahao diol aromatic symmetrical. Hiki iā ia ke hoʻomaikaʻi i ka tensile, paʻakikī, resilience waiwai i MDI-polyurethane elastomers. ʻO HQEE/MDI kahi pūʻulu elastomer PU e like me MOCA/TDI. ʻO nā huahana i hoʻopau ʻia e like me: nā sila punawai aila, nā kaila forklift, ke kāʻei conveyor, nā sila cylinder hydraulic a me nā huahana PU he nui.
Pono nā elastomers LCU i ʻelua ʻāpana kumu: kahi prepolymer i hoʻopau ʻia me nā pūʻulu isocyanate reactive a me kahi mea hoʻonui kaulahao i hoʻopau ʻia i ka hydrogen ikaika. ʻO ka prepolymer kahi huahana e pili ana i ka hopena o ka polyester a i ʻole polyether me isocyanate (TDI,MDI,ADI). ʻO ka mea hoʻonui kaulahao he kaulahao pōkole o diamine a i ʻole diol. Hoʻonui pinepine ʻia nā prepolymers MDI me nā diols.

25kg / pahu pahu a i ʻole e like me kāu mau koi.
Manaʻo: Hiki ke hoʻopaʻa ʻia ka haku melemele a me ka nui e nā koi o nā mea kūʻai aku
Waihona:
Paʻa paʻa. He hygroscopic ka HQEE a e hoʻololi ke kala ma lalo o ka lā. E hoʻopaʻa paʻa ʻia a mālama ʻia i kahi ea. E mālama i ka makū a me ka lā

Hoʻomalu no ka mālama pono ʻana
ʻO ka lawelawe ʻana ma kahi wahi maikaʻi. E hoʻokomo i nā lole pale kūpono. Hōʻalo i ka pili ʻana me ka ʻili a me nā maka. E pale i ka hana ʻana o ka lepo a me nā aerosol. E hoʻohana i nā mea hana ʻole. Kāohi i ke ahi i hana ʻia e ka mahu hoʻolele electrostatic.
