Desmodur RE / Isocyanate RE no nā mea hoʻopili CAS 2422-91-5

Hōʻike Pōkole:

ʻO kā mākou RE kahi mea hana loulou e pili ana i ke keʻa, hoʻohana ʻia i nā mea hoʻopili i hana ʻia e hydroxyl polyurethane, ʻāpana kūlohelohe a synthetic paha, he ikaika paʻa paʻa loa ia i ka pākeke a me ka cab e hoʻohana ʻia ai i ka resin, antioxidant, plasticizing agents, pressure-sensitive etc. hiki ke hoʻohana ʻia ma ke ʻano he crosslinker ma kahi o BAYER's Desmodur RE.

ʻO kā mākou RE kahi mea hana loulou e pili ana i ke keʻa, hoʻohana ʻia i nā mea hoʻopili i hana ʻia e hydroxyl polyurethane, ʻāpana kūlohelohe a synthetic paha, he ikaika paʻa paʻa loa ia i ka pākeke a me ka cab e hoʻohana ʻia ai i ka resin, antioxidant, plasticizing agents, pressure-sensitive etc. hiki ke hoʻohana ʻia ma ke ʻano he crosslinker ma kahi o BAYER's Desmodur RE.

Palapala noi

Pono e hoʻohana i ka lina ʻelua mau mea i loko o ka wā applicaable ma hope o ke kau ʻana iā RE. ʻAʻole pili ka lōʻihi o ka manawa pili i ka ʻike polymer o ka lina, akā ʻo nā mea ʻē aʻe e pili ana (e like me ke kēpau, antioxygen, plasticizer, solvent, a pēlā aku. Ke kokoke i ka wā kūpono, maʻamau i kekahi mau hola a i hoʻokahi lā hana, lina lilo i mea paʻakikī i ka hana, a piʻi koke ka viscosity. ʻO ka hope loa, lilo ia i jelly hiki ʻole ke hoʻololi ʻia. 100 lina kūpono, Hydroxyl polyurethane (helu Polyurethane ma kahi o 20%), RE mahele lāʻau 4-7. Chloroprene rubber (Rubber account ma kahi o 20%) , Ko mākou RE hana 4-7.

Nā Wehewehe Pili ʻē aʻe

Waihona:

E ʻoluʻolu e mālama i loko o ka hue i hoʻopaʻa ʻia ma lalo o 23 ℃, hiki ke mālama paʻa ʻia nā huahana no 12 mau mahina. Hoʻomaʻamaʻa loa ia i ka hānai; e hoʻopuka ia i carbon dioxide a me urea insoluble i ka hopena me ka wai. Inā kū i ka ea teh a i ʻole ka malamalama, e hoʻonui ia i nā loli kala, akā ʻaʻole e hoʻopili ʻia ka hana kūpono.
