Maitiro eKuvandudza Kumisikidza Yekumhanyisa kweCarboxymethyl Cellulose

Kuvandudza iyo yekumisikidza kumhanya kwecarboxymethyl cellulose (CMC) kunosanganisira kukwidziridza kuumbwa, kugadzirisa mamiriro, uye michina paramita kuti uwedzere kupararira, hydration, uye kuparara kweCMC zvimedu. Hedzino nzira dzinoverengeka dzekuvandudza kukurumidza kwekumisikidza kweCMC:

1. Kushandisa Kwepakarepo kana Kukurumidza-Kuparadzira Magiredhi: Funga kushandisa ipapo kana nekukasira-kuparadzira mamakisi eCMC ayo akagadzirirwa kukurumidza hydration uye kupararira. Aya magiredhi ane madiki madiki saizi uye yakakwidziridzwa kunyungudika, ichibvumira kukurumidza kugadzirisa mune aqueous mhinduro.
2. Particle Kuderedza Saizi: Sarudza CMC mamakisi ane madiki madiki saizi, sezvo akatsetseka zvidimbu zvinogara hydrate uye kupararira nekukurumidza mumvura. Kukuya kana kugaya maitiro anogona kushandiswa kuderedza saizi yeCMC poda, kuvandudza kurongeka kwayo.
3. Pre-Hydration kana Pre-Dispersal: Pre-hydrate kana pre-disperse CMC powder mune chikamu chemvura inodiwa isati yawedzera kune iyo huru yekusanganisa mudziyo kana kuumbwa. Izvi zvinobvumira iyo CMC zvidimbu kuzvimba uye kupararira nekukurumidza kana yaunzwa mune yakawanda mhinduro, ichimhanyisa maitiro ekugadzirisa.
4. Optimized Mixing Equipment: Shandisa yakakwirira-shear kusanganisa michina yakadai sehomogenizers, colloid mills, kana high-speed agitators kukurudzira kupararira nokukurumidza uye hydration yeCMC particles. Ita shuwa kuti michina yekusanganisa yakarimwa uye inoshanda nekumhanya kwakaringana uye kusimba kwekugadzirisa kwakaringana.
5. Kudzorwa Tembiricha: Chengetedza tembiricha yemhinduro mukati meiyo yakakurudzirwa renji yeCMC hydration, kazhinji inotenderedza 70-80 ° C kune akawanda mamakisi. Kupisa kwepamusoro kunogona kukurumidza kuita hydration uye kunatsiridza configurability, asi kutarisirwa kunofanira kutorwa kudzivirira kupisa kana gelation yemhinduro.
6. pH Kugadziriswa: Gadzirisa iyo pH yemhinduro kune yakakwana renji yeCMC hydration, kazhinji ine acidic zvishoma kune kwaakarerekera mamiriro. pH mazinga ari kunze kweiyi chiyero anogona kukanganisa kurongeka kweCMC uye inofanirwa kugadziridzwa zvinoenderana uchishandisa asidhi kana mabhesi sezvinodiwa.
7. Shear Rate Kudzora: Dzora mwero wekugera panguva yekusanganisa kuti uve nechokwadi chekupararira uye hydration yeCMC zvimedu pasina kukonzera kushushikana kwakanyanya kana kuderera. Rongedza kusanganisa ma parameter senge blade kumhanya, impeller dhizaini, uye kusanganisa nguva kuti ugone kugadzirika.
8. Hunhu hweMvura: Shandisa mvura yemhando yepamusoro ine mwero wakaderera wetsvina uye yakanyungudika kuti uderedze kukanganiswa neCMC hydration uye kunyungudika. Mvura yakacheneswa kana deionized inokurudzirwa kuti igadziriswe zvakakwana.
9. Nguva yeAgitation: Sarudza iyo yakakwana yekuvhiringika kana kusanganisa nguva inodiwa kupararira kwakazara uye hydration yeCMC mukuumbwa. Dzivisa kusanganisa, izvo zvinogona kukonzera yakawandisa viscosity kana gelation yemhinduro.
10. Kudzora Hunhu: Ita yenguva dzose yemhando yekudzora bvunzo yekutarisa kumisikidzwa kweCMC magadzirirwo, kusanganisira viscosity kuyerwa, particle size yekuongorora, uye kuona kwekuona. Gadzirisa maparamita ekugadzirisa sezvinodiwa kuti uwane kuita kwaunoda uye kuenderana.

Nekushandisa nzira idzi, vagadziri vanogona kuvandudza kukurumidza kwekumisikidza kwecarboxymethyl cellulose (CMC) maumbirwo, kuve nechokwadi chekupararira nekukurumidza, hydration, uye kunyungudika mumashandisirwo akasiyana-siyana akadai sechikafu, mishonga, kutarisirwa kwevanhu, uye zvigadzirwa zvemaindasitiri.
