ʻO Hydroxypropyl Methylcellulose ma ke ʻano he mea hoʻokaʻawale, ʻo nā huahana i loaʻa i nā mea i hoʻonohonoho ʻia a wehe ʻole ʻia, kūpono i ka ʻike kūpono a me ka hana hoʻoponopono maikaʻi loa.Eia nō naʻe, hiki i ka hoʻohana ʻana i ka Hydroxypropyl Methylcellulose wale nō ke kōkua i ka invariance maikaʻi o ka resin.ʻAʻole maikaʻi ka hana holoʻokoʻa o ka resin.ʻO ka hoʻohana pū ʻana o ka hydroxypropyl methylcellulose a me nā ʻano like ʻole o ka alcoholysis degree o ka polyvinyl alcohol hiki ke hoʻomaikaʻi i ka hana o nā huahana, maʻalahi ka maikaʻi a ma ka manawa like hiki ke hōʻemi i ke kumukūʻai.ʻO ka mea hoʻopuehu ka mea nui e hoʻopili ai i ke ʻano o ke ʻano o ka polyvinyl chloride resin.ʻOi aku ka liʻiliʻi o ka neʻe ʻana o ka wai o nā mea hoʻopuehu maʻamau a me ka neʻe ʻana o ke alo me Vinyl chloride monomer, ʻoi aku ka maikaʻi o ka hoʻopuehu ʻana i nā kulu VCM.A pēlā e liʻiliʻi ai ke anawaena o ka PVC resin.ʻOi aku ka ikaika o ka pale ʻana o ka mea hoʻopuehu, ʻoi aku ka kokoke o nā ʻāpana resin PVC i loaʻa a ʻoi aku ka liʻiliʻi o ka porosity.A ʻoi aku ka paʻakikī o ka coalescence intergranular, no laila ua maʻalahi ka hana resins.
No ka laʻana, i loko o ka ʻōnaehana dispersion o ka PVA a me HPC, ʻoi aku ka kiʻekiʻe o ka pae waiʻona o PVA, ʻoi aku ka nui o ka ʻili o ka ʻili o ka wai a ʻoi aku ka ikaika o ka pale ʻana, ʻoiai ua loaʻa kekahi ʻano o ka hydroxypropyl methylcellulose. he hopena hoʻopuehu maikaʻi.No laila, e hoʻohana ana i ka PVA me ke kiʻekiʻe o ka alcoholysis ma ke ʻano he kumu mua
mea hoʻopuehu, a hui pū ʻia a
kekahi nui o ka hydroxypropyl methylcellulose
e like me ka dispersing agent no ka suspension polymerization, ʻoi aku ka maʻalahi o ka hoʻomākaukau ʻana i ka resin PVC e hiki ke hoʻokō i nā koi o ka morphology particle.No ka laʻana, i loko o ka ʻōnaehana dispersion o ka PVA a me HPC, ʻoi aku ka kiʻekiʻe o ka pae waiʻona o PVA, ʻoi aku ka nui o ka ʻili o ka ʻili o ka wai a ʻoi aku ka ikaika o ka pale ʻana, ʻoiai ua loaʻa kekahi ʻano o ka hydroxypropyl methylcellulose. he hopena hoʻopuehu maikaʻi.
