Karolo ea hydroxypropyl methylcellulose

Ts'ebelisong ea thepa ea moaho, hydroxypropyl methyl cellulose HPMC ke tlatsetso ea thepa ea moaho e sebelisoang hangata.hydroxypropyl methyl cellulosee sebelisoa haholo indastering, 'me e na le mefuta e fapaneng, hydroxypropyl methyl cellulose e ka aroloa ka Bakeng sa mofuta oa hang-hang oa metsi a batang le mofuta o chesang oa ho qhibiliha.

HPMC ea hang-hang ea metsi a batang e ka sebelisoa ka phofo ea putty, seretse, sekhomaretsi sa metsi, pente ea metsi le lihlahisoa tsa letsatsi le letsatsi tsa lik'hemik'hale. Hot melt HPMC e atisa ho sebelisoa ka lihlahisoa tsa phofo e omeletseng 'me e kopane ka ho toba le phofo e omeletseng bakeng sa kopo e ts'oanang, e kang putty phofo le seretse, hydroxypropyl methylcellulose e ka sebelisoa haholo ho ntlafatsa ts'ebetso ea samente, gypsum le lisebelisoa tse ling tsa mohaho o nang le metsi. Litšeng tse entsoeng ka samente, e ntlafatsa ho boloka metsi, e eketsa nako ea ho seta le nako e bulehileng, 'me e fokotsa ho emisoa ha phallo.

Hydroxypropyl methylcellulose e ka sebelisoa ho kopanya thepa ea mohaho le kaho, 'me metsoako e omileng ea motsoako e ka kopanngoa ka potlako le metsi ho finyella kapele ho lumellana ho lakatsehang. Cellulose ether e qhibiliha kapele ntle le ho hohla. Propyl methyl cellulose e ka kopanngoa le phofo e omileng ka thepa ea mohaho, e na le litšobotsi tsa ho hasana ha metsi a batang, e ka emisa likaroloana tse tiileng hantle 'me ea etsa hore motsoako o be motle le o ts'oanang. Ho feta moo, e ntlafatsa lubricity le polasetiki, e eketsa machinability, 'me e thusa kaho ea sehlahisoa. Ho boloka metsi ho ntlafalitsoe, nako e telele ea ho sebetsa, ho thusa ho thibela ho phalla ha seretse le lithaele, ho lelefatsa nako ea ho pholisa le ho ntlafatsa ts'ebetso e sebetsang hantle.

Hydroxypropyl methylcellulose e ntlafatsa matla a tlamahano ea li-adhesives tsa lithaele, e ntlafatsa ho hanyetsa ha mapheo a seretse le manonyeletso a boto, ha e eketse feela moea oa seretse, empa hape e fokotsa haholo monyetla oa ho phunyeha, e ka boela ea ntlafatsa Ponahalo ea sehlahisoa mme e ka khona. ntlafatsa ts'ebetso ea anti-sag ea sekhomaretsi sa lithaele.
