Thepa le pono ea cmc

CARBOExxEMEMEBELLULO SONA (CMC) ke ts'ebetso e sebetsang haholo indastering e fapaneng e kang lijo, meriana, lipampiri le meepo. E nkiloe ho contleluulole ea tlhaho, e nang le limela le lisebelisoa tse ling tsa koetliso. CMC ke polymer ea qubu ea metsi ka thepa e ikhethang ho kenyeletsa le lipono, hydration, ho tšoarela.

Sebopeho sa CMC

CMC ke 'muelli oa celluulose e fetotsoeng ka lik'hemik'hale ka ho kenyelletsa lihlopha tsa carboxymemmethl mohahong oa eona. Phetoho ena e ntlafatsa sllubility le hydrophilicity ea cellulose, ka ho etsa joalo e ntlafatsang ts'ebetso. Meru ea cmc e itšetlehile ka tekanyo ea eona ea ho nka karolo (DS) le boima ba limolek'hule (MW). DS e hlalosoa e le palo e tloaelehileng ea lihlopha tsa carboxemeMe ka sehlopha sa Grokose se ka morao, ha MW e bonts'a boholo ba liketane tsa polymer.

E 'ngoe ea thepa ea bohlokoa ea CMC ke stlibility ea eona ea metsi. Cmc e qhibiliha habonolo metsing, e theha tharollo ea li-viscous ka thepa ea pseudoprostic. Boitšoaro bona ba mapolanka ana bo hlahisoa ke lipuisano tse amanang lipakeng tsa limolek'hule, tse bakang ho fokotseha ha Viscosy tlasa khatello ea maikutlo. Tlhaho ea pseudoplatic ea tharollo ea cmc e etsa hore e tšoane le lits'ebetso tse fapaneng tse kang lithibelo, mathata le basebeletsi ba ho emisoa.

Tšobotsi e 'ngoe ea bohlokoa ea CMC ke bokhoni ba eona ba lifilimi. Litharollo tsa cmc li ka bakoa lifiliming tse nang le thepa e ntle ea ho atisa ho lokisa, ponaletso le maemo. Lifilimi tsena li ka sebelisoa e le makhabane a lamate le thepa ea ho paka.

Ntle le moo, CMC e na le thepa e ntle le e bakang thepa. E theha tlamahano e matla ka bongata bo fapaneng, ho kenyelletsa lehong, tšepe, polasetiki le lesela. Thepa ena e lebisitse ho sebelisa cmc ho hlahiseng likotsi, lidheres le enk.

Viscosity ea cmc

Lits'oants'o tsa tharollo ea cmc li ipapisitse le lintlha tse 'maloa tse kang tsa ho tsepamisa mohopolo, li-DS, mocheso, mocheso le ph. Ka kakaretso, tharollo ea cmc e bontša liketsahalo tse phahameng tsa maikutlo a lerato, DS, le MW. Viscosity e boetse e eketseha ka mocheso o fokotsang le ph.

Lits'oants'o tsa tharollo ea cmc li laoloa ke tšebelisano lipakeng tsa liketane tsa polymer le limolek'hule tse solang ka tharollo. Limolek'hule tsa cmc li sebelisana le limolek'hule tsa metsi ka litlamo tsa haedrojene, ho etsa khetla ea Hydrojene ho pota-potiloeng. Le khetla ena ea hydration e fokotsa motsamao oa liketane tsa polymer, ka ho etsa joalo, ho eketsa pono ea tharollo.

Boitšoaro ba litakatso tsa CMC bo tšoauoa ka ho phalla, e hlalosang kamano e teng lipakeng tsa khatello ea kelello le sekhahla sa tharollo. SMC Tharollo e bonts'a boitšoaro bo senang bocha, bo bolelang hore litšoantšiso tsa bona li fetoha ka sekhahla sa shear. Ka litekanyetso tse tlase tsa li-Shear, pono ea likhomo e phahameng, ha e le ka litekanyetso tse phahameng, ha viscooty li fokotseha. Boitšoaro bona bo bobe ba hear bo ka bakoa ho li-polymer tsa polymer ho ea le khatello ea maikutlo, ho fella ka hore li qoelle sets'oants'o sa tikoloho pakeng tsa pono le ho fokotseha ha Vecosity.

Kopo ea CMC

CMC e sebelisoa haholo masimong a fapaneng ka lebaka la thepa ea eona e ikhethang le boitšoaro ba rheological ona. Indastering ea lijo, cmc e sebelisoa e le bolotsana, setaki sa emumuni, emmolifier le papiso e sa ntlafatsoang. E eketsoa lijong tse kang ice cream, lino, li-noas le thepa e halikiloeng ho ntlafatsa sebopeho sa bona, se feto-fetohang le se se nang maemo. CMC e boetse e thibela ho etsoa ha likristale tsa leqhoa lijong tse halikiloeng lijong, tse bakang sehlahisoa se boreleli, se bolila.

Indastering ea meriana, cmc e sebelisoa e le mokhoa oa ho hlaba, ho senyeha le ho laoloa ke tumello ea theko e laoloang. Ntlafatsa ho hatella le ho phoqa ha phofo le ho netefatsa ho tšoana le botsitso ba matlapa. Ka lebaka la thepa ea eona ea hlooho ea hau le ea bione, cmc le eona e sebelisoa e le ea hlokolosi ho ophlhalmic, ntal le mekhoa ea molomo.

Indastering ea pampiri, cmc e sebelisoa e le metsi a mangata a mangata, a kopanya mochine oa khatiso. Ho ntlafatsa ho boloka le ho ts'oara, ho eketsa matla a pampiri le letsoalo, 'me li fana ka sebaka se boreleli ebile se le makhasi. CMC e sebetsa e le tšitiso ea metsi le ea oli, e thibela enke kapa lino tse tsoang ho ho kenella pampiri.

Indastering ea mankale, cmc e sebelisoa e le moemeli oa ho inyenyeletsa, ho hatisa eckener le ho daea chelete. E ntlafatsa hodhesion ea fiber, e ntlafatsa ho kenella ha mebala le boitsebiso ba mebala le ho sebelisa likhohlano le likhohlano. CMC e boetse e fa bonolo le ho satalla ho lesela, ho latela DS le MW ea polymer.

Indastering ea Mine, CMC e sebelisoa e le lipalesa tsa lipalesa, Inhibitor le Rheology Morifier ka ts'ebetso ea liminerale. E ntse e loantša li-sodid le tokiso ea karohano, fokotsa karohano ho tloha sehlopha sa mashala, le ho laola pono ea ho emisoa le botsitso. CMC e boetse e fokotsa tšusumetso ea tikoloho ea ts'ebetso ea morara ka ho fokotsa tšebeliso ea lik'hemik'hale tse chefo le metsi.
