Hydroxypropyl methylcellulose, nke a makwaara dị ka HPMC, bụ cellulose ether nke na-abụghị ionic nke e si na owu a nụchara anụcha, ihe e ji eme polymer eke, nweta site na usoro kemịkalụ dị iche iche. Ọ bụ ntụ ntụ ọcha ma ọ bụ odo odo nke a na-agbaze ngwa ngwa na mmiri. Ka anyị kwuo maka ụzọ mgbaze nke hydroxypropyl methylcellulose.
1. A na-ejikarị Hydroxypropyl methylcellulose eme ihe dị ka ihe mgbakwunye maka ntụ ntụ putty, moto na gluu. A na-etinye ya na moto simenti, enwere ike iji ya dị ka ihe na-ejide mmiri na ihe na-egbochi mmiri iji mee ka ọ dịkwuo mma; a na-etinye ya na ntụ ntụ putty na gluu, enwere ike iji ya dị ka ihe na-ejikọ. Iji melite mgbasa ma gbasaa oge ọrụ, anyị na-ewere Qingquan Cellulose dị ka ihe atụ iji kọwaa ụzọ mgbaze nke hydroxypropyl methylcellulose.
2. A na-ebu ụzọ kpalite hydroxypropyl methylcellulose nkịtị ma fesa ya na mmiri ọkụ, wee tinye ya na mmiri oyi, kpalite ma jụọ oyi ka ọ gbazee;
Kpọmkwem: were 1/5-1/3 nke mmiri ọkụ achọrọ, gwakọta ya ruo mgbe ihe e tinyere ya ga-aza nke ọma, wee tinye akụkụ fọdụrụ n'ime mmiri ọkụ ahụ, nke nwere ike ịbụ mmiri oyi ma ọ bụ ọbụna mmiri ice, wee gwakọta ya ruo n'okpomọkụ kwesịrị ekwesị (10°C) ruo mgbe ọ ga-agbaze kpamkpam.
3. Usoro mmiri mmiri sitere na ihe ndị na-agbaze mmiri nke organic:
Gbasaa hydroxypropyl methylcellulose n'ime ihe na-agbaze ihe dị ndụ ma ọ bụ mee ka ọ dị mmiri mmiri na ihe na-agbaze ihe dị ndụ, wee tinye ma ọ bụ tinye mmiri oyi ka ọ gbazee nke ọma. Ihe na-agbaze ihe dị ndụ nwere ike ịbụ ethanol, ethylene glycol, wdg.
4. Ọ bụrụ na ngwakọta ma ọ bụ mkpuchi emee n'oge ịgbaze, ọ bụ n'ihi na mgbagharị ahụ ezughi oke ma ọ bụ na etinyere ihe nlereanya nkịtị ozugbo na mmiri oyi. N'oge a, kpalie ya ngwa ngwa.
5. Ọ bụrụ na afụfụ na-apụta n'oge a na-agbaze, a pụrụ ịhapụ ha ruo awa 2-12 (oge a kapịrị ọnụ dabere na nha anya nke ihe ngwọta ahụ) ma ọ bụ wepụ ha site na iji ihe nhicha, nrụgide, wdg., ma ọ bụ tinye oke ihe na-eme ka mmiri ghara ịdị ọcha kwesịrị ekwesị.
