Tšebeliso ea sodium carboxymethyl cellulose mokelikeli oa ho cheka

Sodium carboxymethyl cellulose (CMC-Na ka bokhutšoanyane) ke motsoako oa bohlokoa o qhibilihang ka metsi oa polymer 'me o sebelisoa haholo mokelikeli oa ho cheka oli. Thepa ea eona e ikhethang e etsa hore e be karolo ea bohlokoahali tsamaisong ea mokelikeli oa ho cheka.

1. Lintho tsa motheo tsa sodium carboxymethyl cellulose

Sodium carboxymethyl cellulose ke anionic cellulose ether e hlahisoang ke cellulose kamora kalafo ea alkali le chloroacetic acid. Sebopeho sa eona sa limolek'hule se na le palo e kholo ea lihlopha tsa carboxymethyl, tse etsang hore e be le ho qhibiliha ha metsi hantle le botsitso. CMC-Na e ka etsa tharollo e phahameng ea viscosity ka metsing, e nang le thepa e teteaneng, e tsitsitseng le ea ho etsa lifilimi.

2. Ho sebelisoa ha sodium carboxymethyl cellulose mokelikeli oa ho cheka

Thickener

CMC-Na e sebelisoa e le motenya mokelikeli oa ho cheka. Mosebetsi oa eona o ka sehloohong ke ho eketsa viscosity ea mokelikeli oa ho cheka le ho ntlafatsa bokhoni ba oona ba ho jara likotoana tsa majoe le li-cuttings tsa ho cheka. Viscosity e loketseng ea mokelikeli oa ho cheka o ka thibela hantle ho putlama ha lerako le ho boloka botsitso ba seliba.

Mokelikeli o fokotsang tahlehelo ea metsi

Nakong ea ts'ebetso ea ho phunya, mokelikeli oa ho phunya o tla kenella ka har'a li-pores tsa sebopeho, ho baka tahlehelo ea metsi ka har'a mokelikeli oa ho phunya, o sa senyeng feela mokelikeli oa ho phunya, empa hape o ka baka ho putlama ha lerako le ho senyeha ha letamo. E le ho fokotsa tahlehelo ea mokelikeli, CMC-Na e ka etsa kuku e teteaneng ea filthara leboteng la seliba, ka katleho e fokotsa tahlehelo ea ho sefa ha mokelikeli oa ho cheka le ho sireletsa sebopeho le lebota la seliba.

Setlolo

Nakong ea ts'ebetso ea ho phunya, ho ferekanngoa pakeng tsa lerako la ho phunya le lebota la seliba ho tla hlahisa mocheso o mongata, e leng se tla etsa hore sesebelisoa sa ho phunya se be se eketsehileng. Lubricity ea CMC-Na e thusa ho fokotsa khohlano, ho fokotsa ho senyeha ha sesebelisoa sa ho cheka, le ho ntlafatsa ts'ebetso ea ho cheka.

Setsibotsi

Mokelikeli oa ho cheka o ka 'na oa phalla kapa oa senyeha tlas'a mocheso o phahameng le khatello e phahameng, kahoo o lahleheloa ke mosebetsi oa oona. CMC-Na e na le botsitso bo botle ba mocheso le ho hanyetsa letsoai, 'me e ka boloka botsitso ba mokelikeli oa ho cheka tlas'a maemo a thata le ho atolosa bophelo ba eona ba tšebeletso.

3. Mokhoa oa ts'ebetso ea sodium carboxymethyl cellulose

Tokiso ea viscosity

Sebopeho sa limolek'hule tsa CMC-Na se na le palo e kholo ea lihlopha tsa carboxymethyl, tse ka etsang li-hydrogen bond ka metsing ho eketsa viscosity ea tharollo. Ka ho fetola boima ba limolek'hule le tekanyo ea sebaka sa CMC-Na, viscosity ea mokelikeli oa ho cheka o ka laoloa ho finyella litlhoko tsa maemo a fapaneng a ho cheka.

Taolo ea ho sefa

Limolek'hule tsa CMC-Na li ka etsa sebopeho sa marang-rang se nang le mahlakore a mararo ka metsing, se ka etsang kuku e teteaneng ea filthara leboteng la seliba le ho fokotsa tahlehelo ea filtration ea mokelikeli oa ho cheka. Sebopeho sa kaka ea filthara ha se itšetlehe feela ka bongata ba CMC-Na, empa hape le boima ba limolek'hule le tekanyo ea ho fetola.

Lubrication

Limolek'hule tsa CMC-Na li ka adsorbed holim'a karolo ea ho cheka le lebota la seliba ka metsing ho etsa filimi e tlotsang le ho fokotsa coefficient ea likhohlano. Ho feta moo, CMC-Na e ka boela ea fokotsa khohlano pakeng tsa lerako la ho phunya le lebota la seliba ka mokhoa o sa tobang ka ho lokisa viscosity ea mokelikeli oa ho phunya.

Ho tsitsa ha mocheso

CMC-Na e ka boloka botsitso ba sebopeho sa eona sa limolek'hule tlas'a maemo a phahameng a mocheso 'me ha e na monyetla oa ho senyeha ha mocheso. Lebaka ke hobane lihlopha tsa carboxyl limolek'hule tsa eona li ka theha maqhama a tsitsitseng a hydrogen le limolek'hule tsa metsi ho hanela tšenyo e phahameng ea mocheso. Ntle le moo, CMC-Na e boetse e na le khanyetso e ntle ea letsoai mme e ka boloka ts'ebetso ea eona mefuteng ea letsoai. 

4. Mehlala ea Kopo ea Sodium Carboxymethyl Cellulose

Ts'ebetsong ea 'nete ea ho cheka, phello ea ts'ebeliso ea sodium carboxymethyl cellulose e ea hlolla. Ka mohlala, morerong o tebileng oa ho cheka seliba, mokhoa oa mokelikeli oa ho cheka o nang le CMC-Na o ile oa sebelisoa ho laola ka katleho ho tsitsa le ho sefa tahlehelo ea seliba, ho eketsa lebelo la ho phunya, le ho fokotsa litšenyehelo tsa ho phunya. Ho feta moo, CMC-Na e boetse e sebelisoa haholo ho cheka ka metsing, 'me ho hanyetsa letsoai ho etsa hore e sebetse hantle tikolohong ea leoatle.

Tšebeliso ea sodium carboxymethyl cellulose mokelikeli oa ho cheka haholo-holo e kenyelletsa lintlha tse 'nè: ho teteaneng, ho fokotsa tahlehelo ea metsi, ho tlotsa le ho tsitsisa. Sebopeho sa eona se ikhethang sa 'mele le lik'hemik'hale se etsa hore e be karolo ea bohlokoahali tsamaisong ea mokelikeli oa ho cheka. Ka nts'etsopele e tsoelang pele ea theknoloji ea ho cheka, menyetla ea ts'ebeliso ea sodium carboxymethyl cellulose e tla ba kholo. Lipatlisisong tsa nako e tlang, sebopeho sa limolek'hule le mekhoa ea ntlafatso ea CMC-Na e ka ntlafatsoa ho tsoela pele ho ntlafatsa ts'ebetso ea eona le ho fihlela litlhoko tsa tikoloho e rarahaneng ea ho cheka.
