I-MC esetyenziselwa udaka lwepowder eyomileyo iyadingeka ukuba ibe ngumgubo, kunye nomxholo wamanzi aphantsi, kwaye i-fineness nayo ifuna i-20% ~ 60% ye-particle size ibe ngaphantsi kwe-63um.Ukucoleka kuchaphazela ukunyibilika kwe-methyl cellulose ether.I-coarse MC idla ngokufana ne-granules, kwaye kulula ukuyinyibilika emanzini ngaphandle kwe-agglomeration, kodwa izinga lokuchithwa licotha kakhulu, ngoko ke akufanelekanga ukusetyenziswa kwi-powder mortar.
Kwidaka elomileyo lomgubo, i-MC ihlakazwe phakathi kwee-aggregates, iifilisi ezintle kunye nesamente kunye nezinye izinto zesamente.Kuphela umgubo ocolekileyo ngokwaneleyo unokunqanda i-methyl cellulose ether agglomeration xa ixutywa namanzi.Xa i-MC yongezwa ngamanzi ukunyibilikisa i-agglomerates, kunzima kakhulu ukuchithwa kunye nokuchithwa.I-coarse MC ayinayo nje inkcitho, kodwa inciphisa amandla asekuhlaleni odaka.Xa udaka olunjalo olomileyo lusetyenziswa kwindawo enkulu, isantya sokunyanga sodaka lwendawo eyomileyo siya kuncitshiswa kakhulu, kwaye iintanda ziya kubonakala ngenxa yamaxesha ahlukeneyo okuphilisa.Ngodaka olutshiziweyo ngomatshini kunye nokwakhiwa komatshini, ngenxa yexesha elifutshane lokuxuba, imfuno yokucolwa iphezulu.
Ukulunga kwe-MC nako kuchaphazela ukugcinwa kwayo kwamanzi.Ngokubanzi, kwi-methyl cellulose ethers ezineviscosity efanayo kodwa ukucoleka okwahlukileyo, phantsi komyinge wokongeza ofanayo, kokukhona ucoleka kokukhona kungcono ugcino lwamanzi.
Ukugcinwa kwamanzi kwe-MC kuhambelana nobushushu obusetyenzisiweyo, kunye nokugcinwa kwamanzi kwe-methyl cellulose ether kunciphisa ngokunyuka kweqondo lokushisa.Ifakwe kwii-substrates ezishushu phantsi kweemeko eziphezulu zokushisa ukukhawulezisa ukunyangwa kwesamente kunye nokuqina kodaka olomileyo lomgubo.Ukuncipha kwezinga lokugcinwa kwamanzi kukhokelela kwimpembelelo yokusebenza kunye nokumelana nokuqhekeka, kwaye kubaluleke kakhulu ukunciphisa impembelelo yeqondo lokushisa phantsi kwale meko.
Nangona i-methyl hydroxyethyl cellulose ether additives okwangoku ithathwa njengeyona nto iphambili ekuphuhlisweni kwezobuchwepheshe, ukuxhomekeka kwabo kwiqondo lokushisa kuya kukhokelela ekubeni buthathaka kokusebenza kodaka olomileyo lomgubo.Ngonyango oluthile olukhethekileyo kwi-MC, olufana nokwandisa iqondo le-etherification, njl., isiphumo sokugcinwa kwamanzi sinokugcinwa kwiqondo lokushisa eliphezulu, ukwenzela ukuba linike ukusebenza okungcono phantsi kweemeko ezinzima.
