    Nā waiwai a me nā hiʻohiʻona

    ʻO RFE polyisocyanate kahi crosslinker maikaʻi loa no nā mea hoʻopili e pili ana i ka polyurethane, ka lāʻau kūlohelohe a me ka Synthesis rubber. ʻO RFE polyisocyanate kekahi mea pono no ka hoʻomaikaʻi ʻana i ka hoʻopili ʻana o nā mea i hoʻokumu ʻia i ka lāʻau. Hiki ke hoʻohana ʻia ma ke ʻano he crosslinker ma kahi o Bayer's Desmodur RFE.

    Hoʻohana

    Pono e hoʻohana ʻia nā mea hoʻopili ʻelua me ka manawa kūpono ma hope o ka hoʻokomo ʻana i RFE.
    ʻAʻole pili wale ka lōʻihi o ka manawa kūpono i ka ʻike polymer o ka adhesive, akā ʻo nā mea pili ʻē aʻe (e like me resin, Antioxygen, plasticizer, solvent, etc.
    Ke kokoke i ka manawa kūpono, maʻamau he mau hola a i ʻole hoʻokahi lā hana, ʻoi aku ka paʻakikī o ka hoʻopili ʻana, a piʻi koke ka viscosity.
    ʻO ka hope, lilo ia i ka jelly hiki ʻole ke hoʻololi. 100 mea hoʻopili maikaʻi, Hydroxyl polyurethane (Polyurethane account no kahi o 20%), RFE hana 4-7. Chloroprene rubber ( Rubber account for around 20%) , RFE hana 4-7.

    Hoʻopili

    Pākē: 0.75kg / ʻōmole, huina 20 mau hue i loko o ka pahu pahu pahu, 180kg / barela, OR e like me ke noi a nā mea kūʻai aku.

    Waihona

    - Ka waiho ʻana i loko o ka pahu Covestro i hoʻopaʻa ʻia.
    - Manaʻo mālama ʻia: 10 - 30 °C.
    - Pale i ka makū, ka wela a me nā mea ʻē aʻe.
    ʻIke nui: I ka wā o ka lawe ʻana a me ka mālama ʻana i nā wela haʻahaʻa,hiki ke hoʻokumu ʻia nā waihona crystalline.
    Hoʻoheheʻe hou kēia mau mea i ka lumi wela. ʻO kaʻoluʻolu loa ka huahana i ka makū a hana me ka wai e hana i ke kalaponadioxide a me ka urea hiki ole ke hooheheeia.
    No laila, pono e mālama pono i nā pahusila ʻia. ʻO ke komo ʻana o ka wai i kēlā me kēia ʻano (nā pahu wai, anhydrousnā mea hoʻoheheʻe, ea mākū) pono e pale ʻia e like me ke ʻano o ka hoʻokumu ʻana o ke kalaponahiki i ka dioxide ke hoʻonui i ka piʻi ʻana o ke kaomi i loko o nā pahu.
    ʻO ka ʻike ʻana i ka ea a/a i ʻole ka mālamalama e hoʻoikaika i ka ʻili akā ʻaʻohe hopena o kēianā waiwai hana ma ka laulā.
