HPMC E 50
ʻO EipponCellHPMC E 50 Hydroxypropyl methylcellulose kahi ʻano dispersant kaulana i hoʻohana ʻia i ka ʻoihana polyvinyl chloride (PVC).Hoʻohana ʻia ia i ka wā o ka polymerization hoʻokuʻu ʻia o ka vinyl chloride e hōʻemi maikaʻi i ka ʻāʻī waena ma waena o ka vinyl chloride monomer (VCM) a me ka wai.ʻO kēia hoʻohaʻahaʻa ʻana i ka haʻalulu kōkua e hoʻopuehu like a paʻa i ka VCM i loko o ka wai.Eia hou, kōkua ia i ka pale ʻana i ka hoʻohui ʻana o nā kulu VCM i ka hoʻomaka ʻana o ke kaʻina polymerization a pale i ka coalescence ma waena o nā ʻāpana polymer i ka pae waena a ma hope.I loko o ka ʻōnaehana polymerization hoʻokuʻu, lawelawe ʻo EipponCellHPMC E 50 Hydroxypropyl methylcellulose i kahi kumu ʻelua o ka hoʻopuehu a me ka pale kūpaʻa.

HPMC F 50
ʻO EipponCellHPMC F 50, kahi hydroxypropyl methyl cellulose, hana ma ke ʻano he dispersant i ka ʻoihana PVC.I ke kaʻina hana polymerization hoʻokuʻu o vinyl chloride, hoʻohana mau ʻia nā dispersants i nā pūhui polymer e like me ka polyvinyl alcohol a me ka cellulose ether.I ka wā e hoʻoulu ai, hoʻomaʻamaʻa lākou i ka hoʻokumu ʻana o nā droplets me nā nui kūpono.Ua kapa ʻia kēia mana ʻo ka dispersing ability o ka dispersant.Hoʻohui ʻia, hoʻopili ʻia ka dispersant ma luna o ka ʻili o ka vinyl chloride monomer droplets, e hana ana i kahi papa pale e pale ai i ka hōʻuluʻulu droplet a hoʻopaʻa iā lākou.ʻIke ʻia kēia hopena ʻo ka hiki ke hoʻopaʻa colloid o ka dispersant.
