Isiphumo sokuncamathela
Ukubambelela kwe-CMC kwi-slurry kubangelwa ukusekwa kwesakhiwo sothungelwano oluqinileyo ngokusebenzisa iibhondi ze-hydrogen kunye nemikhosi ye-van der Waals phakathi kwee-macromolecules.Xa amanzi engena kwibhloko ye-CMC, amaqela e-hydrophilic anomtsalane omncinci wamanzi adumba, ngelixa uninzi lwe-hydrophilic luhlukana ngokukhawuleza emva kokudumba.Amaqela e-hydrophilic angabonakaliyo kwimveliso ye-CMC ibangela ukungahambelani kobukhulu beqhekeza leemicelles.Ukudumba kwe-hydration kwenzeka ngaphakathi kweemicelles, okwenza umaleko wamanzi adibeneyo ngaphandle.Kwinqanaba lokuqala lokuchithwa, ii-micelles zikhululekile kwi-colloid.Amandla e-van der Waals ngokuthe ngcembe azisa ii-micelles kunye, kwaye umaleko wamanzi adibeneyo wenza isakhiwo sothungelwano ngenxa ye-asymmetry yobukhulu kunye nokumila.Ubume benethiwekhi ye-CMC ene-fibrous inomthamo omkhulu, ukunamathela okuqinileyo, kunye nokunciphisa iziphene ze-glaze.
levitation Effect
Ngaphandle kwezongezo, i-glaze slurry iya kuhlala ngenxa yobunzima ngokuhamba kwexesha, kwaye ukongeza inani elithile lodongwe akwanelanga ukukhusela oku kungenzeki.Nangona kunjalo, ukongezwa kwesixa esithile se-CMC kunokwenza isakhiwo sothungelwano esixhasa ubunzima beemolekyuli zeglaze.Iimolekyuli ze-CMC okanye ii-ion zolula kwi-glaze kwaye zithatha indawo, zithintela ukunxibelelana kweemolekyuli ze-glaze kunye namasuntswana, okuphucula ukuzinza kwe-dimensional ye-slurry.Ngokukodwa, i-anion ye-CMC ehlawuliswa kakubi igxotha iincinci zodongwe ezibiziweyo, ezikhokelela ekunyusweni kokunyuka kwe-glaze slurry.Oku kuthetha ukuba i-CMC inokumiswa kakuhle kwi-glaze slurry.Isakhiwo sothungelwano esenziwe yi-CMC sikwanceda ukunciphisa iziphene ze-glaze kunye nokuqinisekisa ukugqitywa komphezulu ogudileyo.Ngokubanzi, i-CMC idlala indima ebalulekileyo kuzinzo kunye nokunqunyanyiswa kwe-glaze slurry, ebalulekileyo ekufezekiseni iziphumo ezingaguqukiyo kunye nezikumgangatho ophezulu kwinkqubo yokukhenkceza.
Imibuzo emayithathelwe ingqalelo xa ukhetha i-CMC
Ukusetyenziswa ngokufanelekileyo kwe-CMC ekuveliseni i-glaze kunokuphucula kakhulu umgangatho wemveliso yokugqibela.Ukuqinisekisa isiphumo esihle, kukho amanqaku amaninzi aphambili ekufuneka alandelwe.Okokuqala, kubalulekile ukujonga ukucaciswa kwemodeli yeCMC ngaphambi kokuthenga kwaye ukhethe ingcaciso efanelekileyo yemveliso.Xa ukongeza i-CMC kwi-glaze ngexesha lokusila, kunokunceda ukuphucula ukusebenza kakuhle.Ingqalelo kufuneka ihlawulwe kwakhona kumlinganiselo wamanzi ukuya kwi-CMC xa ugalela amanzi ukuphumeza umphumo omkhulu.
I-glaze slurry kufuneka ivunyelwe ukubola usuku okanye ezimbini ukuqinisekisa ukuba izinzile ngokwaneleyo kwaye i-CMC inokudlala isiphumo esihle.Kwakhona kubalulekile ukulungelelanisa ngokufanelekileyo isixa se-CMC esidityanisiweyo ngokotshintsho lwamaxesha onyaka, kunye nelona longezwe ehlotyeni, ubuncinci ebusika, kunye noluhlu lwe-0.05% ukuya kwi-0.1% phakathi.Ukuba idosi ishiywe ingatshintshwanga ebusika, inokubangela ukugqabhuka kweglaze, ukoma okucothayo, kunye neglaze encangathi.Ngakolunye uhlangothi, ukungonelanga kwedosi kuya kubangela umphezulu oshinyeneyo kunye orhabaxa.
Ehlotyeni, ubushushu obuphezulu bunokuthoba i-viscosity ye-CMC ngenxa yempembelelo yebhaktiriya.Ngoko ke, kuyimfuneko ukwenza umsebenzi wokuchasana nokubola kunye nokongeza izongezo ezifanelekileyo zokugcina umgangatho weCMC.Ekugqibeleni, xa usebenzisa i-glaze, kuyacetyiswa ukuba uyihluze nge-sieve engaphezulu kwe-100 mesh ukukhusela intsalela ye-CMC ekuchaphazeni i-glaze surface ngexesha lokudubula.Ngokulandela ezi zikhokelo, i-CMC ingasetyenziswa ngokufanelekileyo kwimveliso ye-glaze ukuphucula umgangatho wemveliso.
