Hydroxypropyl methylcellulose, makwaara dị ka HPMC, bụ nonionic cellulose ether enwetara site na owu a nụchara anụcha, ihe polymer eke, site na usoro usoro kemịkal. Ọ bụ ntụ ntụ na-acha ọcha ma ọ bụ ntakịrị odo na-adị mfe soze na mmiri. Ka anyị kwuo maka usoro mgbasa nke hydroxypropyl methylcellulose.
1. A na-ejikarị Hydroxypropyl methylcellulose mee ihe dị ka ihe mgbakwunye maka ntụ ntụ, ngwa agha na gluu. Agbakwunyere na ciment ciment, a pụrụ iji ya mee ihe dị ka onye na-ejigide mmiri na-eme ka ọ dịkwuo elu; agbakwunyere na putty ntụ ntụ na gluu, enwere ike iji ya dị ka ihe nkedo. Iji meziwanye mgbasa na ịgbatị oge ọrụ, anyị na-ewere Qingquan Cellulose dịka ọmụmaatụ iji kọwaa usoro mgbasa nke hydroxypropyl methylcellulose.
2. A na-ebu ụzọ kpalie hydroxypropyl methylcellulose nkịtị ma fesaa ya na mmiri ọkụ, wee gbakwunye ya na mmiri oyi, kpalie na mma ka igbari;
Kpọmkwem: were 1 / 5-1 / 3 nke mmiri ọkụ achọrọ, kpalie ruo mgbe ngwaahịa agbakwunyere na-azacha kpamkpam, tinyezie akụkụ nke fọdụrụ na mmiri ọkụ, nke nwere ike ịbụ mmiri oyi ma ọ bụ ọbụna mmiri ice, ma kpalie ya. okpomọkụ kwesịrị ekwesị (10 Celsius C) ruo mgbe agbazere kpamkpam.
3. Organic mgbaze wetting usoro:
Gbasaa hydroxypropyl methylcellulose n'ime ihe mgbaze organic ma ọ bụ mee ya na ihe mgbaze organic, wee tinye ma ọ bụ tinye mmiri oyi ka ọ gbazee nke ọma. Ihe mgbaze organic nwere ike ịbụ ethanol, ethylene glycol, wdg.
4. Ọ bụrụ na agglomeration ma ọ bụ wrapping eme n'oge mgbasa, ọ bụ n'ihi na-akpali akpali ezughị ma ọ bụ ndị nkịtị nlereanya na-agbakwunyere ozugbo na mmiri oyi. N'oge a, kpalie ngwa ngwa.
5. Ọ bụrụ na a na-emepụta egosipụta n'oge mgbasa, ha nwere ike ịhapụ maka awa 2-12 (oge a kapịrị ọnụ na-adabere na nkwụsi ike nke ngwọta) ma ọ bụ wepụ ya site na ịmegharị ihe, nrụgide, wdg, ma ọ bụ na-agbakwụnye ego kwesịrị ekwesị nke onye na-emepụta ihe.
Mkpachapụ anya
A na-ekewa Hydroxypropyl methylcellulose n'ime ụdị mgbaze ngwa ngwa na ngwa ngwa. Enwere ike igbaze hydroxypropyl methylcellulose ozugbo na mmiri oyi.
