1. Hoʻokaʻawale ʻia ʻo HPMC i ke ʻano koke a me ke ʻano dispersing wikiwiki.
Loaʻa i ka ʻano hoʻopuehu wikiwiki HPMC ka leka S ma ke ʻano he suffix.Pono e hoʻohui ʻia ʻo Glyoxal i ka wā o ke kaʻina hana.
ʻAʻole hoʻohui ka ʻano hoʻopuehu wikiwiki HPMC i nā leka, e like me "100000" ʻo ia hoʻi "100000 viscosity fast-dispersing HPMC".
2. Me ka S a me ka ole, he okoa na ano
Puka koke ka HPMC i ka wai anuanu a nalowale i ka wai.ʻAʻohe viscosity o ka wai i kēia manawa no ka mea ua hoʻopuehu wale ka HPMC i ka wai a ʻaʻole i hoʻoheheʻe maoli ʻia.Ma hope o ʻelua mau minuke, piʻi mālie ka viscosity o ka wai, e hana ana i kahi wai viscous māmā.Colloid mānoanoa.
Hiki ke hoʻopuehu koke ʻia ka HPMC i ka wai wela ma kahi o 70°C.Ke hāʻule ka mahana i kahi mahana, ʻike mālie ka viscosity a hiki i ka hoʻokumu ʻana o kahi colloid viscous transparent.
3. Me ka S a ʻole paha, ʻokoʻa ke kumu
Hiki ke hoʻohana wale ʻia ka HPMC i ka pauka putty a me ka mortar.I loko o nā glues wai, nā pena a me nā lako hoʻomaʻemaʻe, hiki mai nā puʻupuʻu a lilo i mea hiki ʻole ke hoʻohana.
ʻO ka hoʻopuehu wikiwiki ʻana i ka HPMC he nui nā noi.Hiki ke hoʻohana ʻia no ka pauka putty, mortar, ke kāpili wai, pena, a me nā lako hoʻomaʻemaʻe me ka ʻole o nā contraindications.
ʻano hoʻoheheʻe
1. E lawe i ka nui o ka wai wela i makemake ʻia, e hoʻokomo i loko o kahi pahu a hoʻomehana iā ia ma luna o 80 ℃, a laila e hoʻohui mālie i kēia huahana me ka hoʻoulu lohi.Ke lana nei ka cellulose ma ka ʻili wai i ka wā mua, akā e hoʻopuehu mālie a hana i kahi slurry like.E hooluolu i ka hooluu ana.
2. A i ʻole e wela i ka 1/3 a i ʻole 2/3 o ka wai wela ma luna o 85 ° C, e hoʻohui i ka cellulose e loaʻa i kahi slurry wai wela, a laila e hoʻohui i ke koena o ka wai anuanu, e hoʻoulu mau, a hoʻomaha i ka hui ʻana.
3. 'O ka nui o ka mesh maika'i 'o Cellulose a noho 'ia ma ke 'ano he mau 'āpana li'ili'i i loko o ka pauka i ho'oulu 'ia.E hoʻoheheʻe koke ʻia ke ʻike ʻia i ka wai e hana i ka viscosity pono.
4. E hoʻohui i ka cellulose me ka mālie a me ke kaulike ma ka lumi wela, e hoʻoulu mau ana a hiki i ka puka ʻana o kahi hopena maʻemaʻe.
He aha nā mea e pili ana i ka paʻa ʻana o ka wai o ka hydroxypropyl methylcellulose?
ʻO ka paʻa ʻana o ka wai o nā huahana hydroxypropyl methylcellulose HPMC ponoʻī e hoʻopilikia pinepine ʻia e nā kumu penei:
1. Homogeneity o cellulose ether HPMC
Hāʻawi like ʻia nā hui HPMC methoxy a me hydroxypropoxy like ʻole a loaʻa ka paʻa wai kiʻekiʻe.
2. Cellulose ether HPMC wela gel wela
ʻO ke kiʻekiʻe o ka mahana o ka gel conductive thermal, ʻoi aku ka kiʻekiʻe o ka paʻa wai;ʻoi aku ka haʻahaʻa o ka mālama ʻana i ka wai.
3. Viscosity o cellulose ether HPMC
Ke piʻi ka viscosity o HPMC, piʻi pū ka nui o ka mālama ʻana i ka wai;ke piʻi ka viscosity i kahi pae, ʻoi aku ka maʻalahi o ka piʻi ʻana o ka paʻa wai.
ʻO ka helu hoʻohui HPMC cellulose ether
ʻOi aku ka nui o ka cellulose ether HPMC i hoʻohui ʻia, ʻoi aku ka kiʻekiʻe o ka pae paʻa wai a ʻoi aku ka maikaʻi o ka hopena paʻa wai.
Ma ka laulā o 0.25-0.6%, piʻi wikiwiki ka nui o ka mālama ʻana i ka wai i ka piʻi ʻana o ka nui o ka hoʻohui;ke piʻi aʻe ka nui o ka hoʻohui, e lohi ka piʻi ʻana o ka nui o ka mālama ʻana i ka wai.
