HPMC gel wela

He nui nā mea hoʻohana e hoʻolohe i ka pilikia o ka hydroxypropyl methyl cellulose HPMC gel wela. I kēia mau lā, ʻike ʻia ka hydroxypropyl methyl cellulose HPMC e ka viscosity, akā no kekahi mau wahi kūikawā a me nā ʻoihana kūikawā, ʻike wale ʻia ka viscosity o ka huahana. ʻAʻole lawa, hōʻike pōkole kēia i ka hydroxypropyl methylcellulose HPMC gel wela.

ʻO ka ʻike o ka hui methoxy e pili pono ana i ke kiʻekiʻe o ka etherification o ka cellulose ether. Hiki ke hoʻololi ʻia ka ʻike o ka pūʻulu methoxy ma ke kāohi ʻana i ke ʻano, ka wela o ka hopena a me ka manawa pane. I ka manawa like, pili ka pae o ka etherification i ke kiʻekiʻe o ka hoʻololi ʻana o ka hydroxyethyl a i ʻole hydroxypropyl. No laila, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai o cellulose ether me ka wela gel kiʻekiʻe. Pono e ʻimi ʻia kēia kaʻina hana, no laila ʻaʻole no ka haʻahaʻa o ka ʻike methoxy, haʻahaʻa ke kumukūʻai o ka cellulose ether, akā, ʻoi aku ka kiʻekiʻe o ke kumukūʻai.

He 25% ko QUALICELL hydroxypropyl methyl cellulose HPMC He wahi koʻikoʻi ka mahana gel no ka hoʻohana ʻana i ka cellulose ether. Ke ʻoi aku ka mahana o ka ambient i ka mahana gel, e kahe ka cellulose ether i waho o ka wai a nalowale kona paʻa wai. ʻO ka mahana o ka cellulose ether gel o Qualicell he 65 degere, hiki ke hoʻokō pono i nā pono o ka mortar a me ka hoʻohana ʻana i ka putty (koe wale no nā kaiapuni kūikawā). Inā kūʻai ʻoe iā QualiCell HPMC, e ʻoluʻolu e hoʻomaopopo mua inā loaʻa iā ʻoe nā koi kūikawā.
