Aia he 30000 mau hue RFE i loko o ka waihona. Hiki ke lawe wikiwiki. ʻOi aku ka nui me ka uku hoʻemi. Manaʻolana ʻaʻole ʻoe e poina.
Inā makemake ʻoe, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa

| Pūʻolo | 750 g / hue, huina 20 hue i hoʻokahi pahu pahu, 180kg / barela, A i ʻole e like me ke noi a nā mea kūʻai aku. |
Kahi mea hou aʻe：Hiki i ka hui ke noiʻi a hoʻomohala i nā huahana hou e like me ke koi kūikawā o kā mākou mea kūʻai.
Nā hiʻohiʻona:ʻO RFE polyisocyanate kahi crosslinker maikaʻi loa no nā adhesives 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 ʻikepili 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
hana, 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.
Waihona: E ʻoluʻolu e mālama ʻia i loko o ka ipu i hoʻopaʻa ʻia ma lalo o 23℃, hiki ke mālama mau ʻia nā huahana no ʻeono mahina. ʻO nā huahana Crosslinker moʻo a pau e maʻalahi loa i ka makū; e hana mai ia i kalapona kalapona a me ka urea hiki ole ke hooheheeia me ka wai. Inā ʻike ʻia i ka ea a i ʻole ka mālamalama, e wikiwiki ia i nā hoʻololi kala o nā huahana, akā ʻaʻole e pili ka hana kūpono.
