Hoʻohana kumu
ʻO ka Neopentanediol dimethacrylate kahi mea hoʻopili crosslinking koʻikoʻi i hoʻohana nui ʻia i nā māla o ke aniani organik, ka uhi ʻana, sol-wikiwiki a me nā ʻoihana lāʻau.
Hoʻopili ʻia
ʻO nā pahu pahu a i ʻole ka pahu kila kila，200kg paona ʻupena.
ʻO ka lawe ʻana a me ka mālama ʻana
E hōʻalo i ka ua a me ka wela kiʻekiʻe i ka lawe ʻana. E mālama i nā huahana i loko o nā kūlana anuanu, malu a me ka ea, e mālama mamao mai ke ahi.
Nā ʻōlelo kuhikuhi maʻamau
Hiki ke ahi ! Hiki ke hoʻomaka ʻia ka polymerization e ka hoʻohaumia ʻana me nā peroxides, nā pūhui aze, nā ion metala kaumaha, tert. Amine, Scompounds. Hoʻokomo ʻia ka polymerization e ka mālamalama. Pono ka saturation oxygen i loko o ka monomer no ka paʻa. ʻAʻole pono ka mahana o ka mālama ʻana ma mua o 35.

ʻO ka Neopentanediol dimethacrylate kahi mea hoʻohana crosslinking nui i hoʻohana nui ʻia i nā māla o ke aniani organik, ka uhi ʻana, ka wikiwiki a me nā ʻoihana ʻōpala.
