HPMC F 50

ʻO EipponCell HPMC F 50 kahi mea hoʻopuehu nui i hoʻohana ʻia i ka ʻoihana polyvinyl chloride (PVC).I ka wā o ka polymerization o ka vinyl chloride, hana ia i kekahi mau hana.ʻO ka mea mua, hoʻemi ia i ka ʻāʻī ma waena o ka vinyl chloride monomer (VCM) a me ka wai, e hoʻomaʻamaʻa i ka ʻaʻahu a me ka hoʻopuehu paʻa o VCM i loko o ka wai.ʻO ka lua, pale ia i ka hoʻohui ʻana o nā droplets VCM i ka pae mua o ka polymerization.ʻO ka mea hope loa, ke kāohi nei ia i ka coalescence ma waena o nā ʻāpana polymer i ka waena a me nā pae hope o ke kaʻina hana.Ma ka ʻōnaehana polymerization hoʻokuʻu, hoʻokani ʻo EipponCell HPMC F 50 i ʻelua kuleana o ka hoʻopuehu ʻana i ka VCM a me ka hōʻoia ʻana i ka paʻa.

ʻO ka polyvinyl chloride (PVC) resin me kahi haʻahaʻa haʻahaʻa o ka polymerization e pili ana i ka resin PVC me kahi degere polymerization ma lalo o 800. ʻO kēia ʻano resin, no ka haʻahaʻa haʻahaʻa molekala, kiʻekiʻe ʻike ʻia, ka wai hehee maikaʻi, ka manawa plasticizing pōkole, a me ka maʻalahi. ʻO ka hana ʻana, loaʻa nā noi nui i ka hana ʻana i ka pepa, nā mea hoʻopili paipu hoʻoheheʻe ʻia, ka puhi ʻana, a me ka hana ʻana i nā resins i hoʻololi ʻia (e like me ka chlorinated polyvinyl chloride ma o ka chlorination hohonu o ka vinyl chloride resin), a me nā mea ʻē aʻe.Eia nō naʻe, ʻo ka resin PVC me kahi haʻahaʻa o ka polymerization e hōʻike ana i ka porosity haʻahaʻa a me nā ʻāpana resin compact.ʻO ke kiʻi ʻoniʻoni i hana ʻia e ka copolymerization graft o nā dispersants a me ka vinyl chloride ke ʻano mānoanoa, hiki ke hoʻopilikia i ka hana o ka resin a me ka hoʻololi ʻana.
