I-Etherification Synthetic Principle ye-Hydroxypropyl Methyl Cellulose (HPMC)
I-Hydroxypropyl methylcellulose (HPMC), i-cellulose eluhlaza, ingacolisiswa ukotini noma i-pulp yokhuni, kuyadingeka kakhulu ukuyichoboza ngaphambi kwe-alkalization noma ngesikhathi se-alkalization, futhi ukuchotshozwa kungokusebenzisa amandla omshini Ukubhubhisa isakhiwo esihlanganisiwe sezinto zokusetshenziswa kwe-cellulose ukunciphisa izinga cr...Funda kabanzi -
IHydroxypropyl methyl cellulose ether yokwakha
Izici zomkhiqizo we-hydroxypropyl methylcellulose ukuze kwakhiwe Incibilika emanzini nakwezinye izincibilikisi eziphilayo. Ingancibilika emanzini abandayo. Ukugxila kwayo okuphezulu kuncike kuphela ku-viscosity. I-solubility iyashintsha nge-viscosity. Lapho i-viscosity iphansi, i-solubi inkulu kakhulu ...Funda kabanzi -
Izakhiwo zebanga lezemithi HPMC
1. Izakhiwo eziyisisekelo ze-HPMC Hypromellose, igama eligcwele i-hydroxypropyl methylcellulose, elibizwa ngokuthi HPMC. Ifomula yayo yamangqamuzana ithi C8H15O8-(C10Hl8O6)n-C8Hl5O8, futhi isisindo sayo samangqamuzana silinganiselwa ku-86000. Lo mkhiqizo uyingxenye ye-semi-synthetic, eyingxenye ye-methyl nengxenye ye-polyhydroxypropyl ether ...Funda kabanzi -
Izakhiwo ze-sodium carboxymethyl cellulose kanye nesingeniso somkhiqizo
I-sodium carboxymethyl cellulose, ebizwa ngokuthi i-carboxymethyl cellulose (CMC) iwuhlobo lwe-fiber ether ephezulu ye-polymer elungiswe ukuguqulwa kwamakhemikhali kwe-cellulose yemvelo. Ukwakheka kwayo ngokuyinhloko iyunithi ye-D-glucose ngo-β (1→4) Okhiye baxhunywe ndawonye. I-CMC imhlophe noma i-milky white fibrous powder...Funda kabanzi -
Ukuhlakazwa nokuhlakazwa kwemikhiqizo ye-CMC
Xuba i-CMC ngqo namanzi ukuze wenze ingcina yeglue ukuze isetshenziswe kamuva. Lapho ulungisa iglue ye-CMC, qala wengeze inani elithile lamanzi ahlanzekile ku-batching ithangi ngethuluzi elinyakazayo, futhi lapho idivayisi enyakazayo ivuliwe, kancane kancane futhi ngokulinganayo ufafaze i-CMC ku-batching tank, ugovuze ngokuqhubekayo...Funda kabanzi -
Izici zohlelo lokusebenza lwe-CMC kanye nezidingo zenqubo ekudleni
Ukusetshenziswa kwe-CMC kunezinzuzo eziningi ngaphezu kwamanye ama-thickeners okudla: 1. I-CMC isetshenziswa kabanzi ekudleni nasezicini zayo (1) I-CMC inokuqina okuhle Ekudleni okubandayo njengama-popsicles no-ayisikhilimu, ukusetshenziswa kwe-CMC kungalawula ukwakheka kweqhwa. amakristalu, akhuphule izinga lokunwetshwa futhi agcine iyunifo...Funda kabanzi -
Yiziphi izici ze-carboxymethyl cellulose?
I-Carboxymethyl cellulose iyisithako samakhemikhali esivame kakhulu, esingahlukaniswa sibe yizinto ezibonakalayo kanye nezakhiwo zamakhemikhali. Ngokwendlela ebukeka ngayo, iwuhlobo lwefayibha emhlophe, kwesinye isikhathi impushana elingana nezinhlayiyana, ayinambitheki, iyinto engenaphunga nenganambitheki, kanye ne-carboxymeth...Funda kabanzi -
