Nā hi?ohi?ona huahana: Dispersion: ?O ka hana ho?opuehu ho?omaha ho?omaha maika?i loa, ma ka ho?oponopono ?ana i ka ha?alulu o ka ?ili a me ka no?ono?o ?ana, e ho?opuehu ?ia ka monomer i nā ?āpana maika?i. Ho?oku?u: ho?omaika?i i ka resin thermal stability a me ka mālama ?ana i ka hā?awi ?ana i ka nui o nā ?āpana, ho?omaika?i i ke ?ano o nā ?āpana a me ka pu?upu?u viscosity, ho?emi i ka ulu ?ana o ka fisheye. Adsorbability: ho?omaika?i i ka maika?i o ka resin a me nā huahana i hana ?ia, i hiki ai i ka resin PVC ke hana i kahi kīnā ?ole, ho?onui i ka absorption o ka plasticizer.
?O ka ?ōnaehana polymerization PVC i ho?omākaukau ?ia e ka HPMC ki?eki?e, me ka hō?oia i ka ho?okō ?ana o ka hana i nā kūlana honua, akā loa?a pū kekahi mau waiwai kino maika?i, nā ?āpana ?āpana maika?i a me nā ?ano ho?ohehe?e rheological maika?i loa. I loko o ka ?ōnaehana dispersant pūhui, ?oi aku ka maika?i o ka polyvinyl alcohol (PVA) me nā degere like ?ole o ka alcoholysis a me ka polymerization a me ka hydroxypropyl methylcellulose (HPMC) hui hui ?oi aku ka maika?i, ?oi aku ka maika?i o ka porosity o ka resin, a ?oi aku ka maika?i o ka absorption o ka plasticizer.
