Kana zvasvika pakunyungudika kwemethyl cellulose, inonyanya kureva kunyungudika kwe sodium carboxymethyl cellulose.
Sodium carboxymethyl cellulose ichena kana yero flocculent faibha poda, isinganhuhwi uye isinganakidze. Inonyungudika nyore nyore mumvura inotonhora kana inopisa, ichigadzira mhinduro yakajeka ine imwe viscosity.
Chii chinonzi solubility? Kutaura zvazviri, zvinoreva huremu hwe solute yakanyungudutswa nechimwe chinhu chakasimba muchimiro chakazara mu100g yezvinonyungudutsa pane imwe tembiricha. Izvi zvinonyungudika. Iyo solubility yemethyl cellulose ine hukama nezvikamu zviviri. Kune rumwe rutivi, zvinoenderana nemaitiro e carboxymethyl cellulose, uye kune rumwe rutivi, ine hukama hushoma nekunze kwekushisa, humidity, pressure, solvent type, nezvimwewo. tembiricha, uye ichawedzera nekuwedzera tembiricha.
Pane nzira nhatu dzekunyungudutsa methylcellulose:
1. Organic solvent wetting nzira. Iyi nzira inonyanya kuparadzira kana kunyorova MC organic solvents senge ethanol uye ethylene glycol pachine nguva, uye wobva wawedzera mvura kunyungudika.
2. Nzira yemvura inopisa. Nekuti MC haina kunyungudika mumvura inopisa, MC inogona kuparadzirwa zvakaenzana mumvura inopisa padanho rekutanga. Pakutonhora, nzira mbiri dzinotevera dzinogona kuteverwa:
(1) Unogona kutanga wawedzera huwandu hwakakodzera hwemvura inopisa mugaba wopisa kusvika pa70°C. MC yakawedzerwa zvishoma nezvishoma zvishoma nezvishoma, zvishoma nezvishoma ichiita slurry, iyo yakabva yatonhodzwa nekukurudzira.
(2) Wedzera 1/3 yehuwandu hunodiwa hwemvura mumudziyo wakagadzika, kupisa kusvika ku70 ° C, uye kuparadzira MC maererano nenzira ichangobva kutaurwa, uye wozogadzira slurry yemvura inopisa; wobva wawedzera kumvura inotonhora Enda kune slurry, fambisa zvakanaka uye utonhodze musanganiswa.
3. Powder kusanganisa nzira. Iyi nzira inonyanya kuparadzira MC hupfu zvimedu uye zvakaenzana poda zvigadzirwa nekuoma kusanganisa, uyezve kuwedzera mvura kunyungudika.
