Methylcellulose (MC) imvura inonyungudika cellulose inobuda nekukora, kugadzira firimu, kudzikamisa uye zvimwe zvivakwa. Inowanzoshandiswa mune zvekudya, mishonga, kuvaka, cosmetics uye mamwe minda. Maitiro ayo ekunyungudika mumvura akasarudzika uye zviri nyore kugadzira colloidal mhinduro, saka iyo chaiyo yekusanganisa nzira yakakosha pakuita kwayo.
1. Hunhu hwemethylcellulose
Methylcellulose haisi nyore kunyungudika pane tembiricha yekamuri, uye kunyungudika kwayo kunokanganisa zvakanyanya nekushisa. Mumvura inotonhora, methylcellulose inogona kuumba homogeneous mhinduro nekupararira zvishoma nezvishoma; asi mumvura inopisa, ichakurumidza kuzvimba uye gel. Nokudaro, kutonga kwekushisa kwakakosha zvikuru pakusanganisa methylcellulose nemvura.
2. Kugadzirira
Methylcellulose: Inowanikwa kubva kune vatengesi vemakemikari mbishi zvinhu kana marabhoritari.
Mvura: Inokurudzirwa kushandisa mvura yakasvibiswa kana yakasvibiswa kuti irege kusvibiswa mumvura yakaoma kubva pakukanganisa kuparara kwemethylcellulose.
Kusanganisa Equipment: Zvichienderana nezvido zvako, musanganisi wemaoko ari nyore, musanganiswa wepamusoro-wekumhanya, kana michina yekusanganisa maindasitiri inogona kushandiswa. Kana iri diki-mwero murabhoritari kushanda, zvinokurudzirwa kushandisa magineti stirrer.
3. Kusanganisa danho
Method 1: Mvura inotonhora yekuparadzira nzira
Cold water premix: Tora huwandu hwakakodzera hwemvura inotonhora (zvichida 0-10 ° C) woiisa mumudziyo wekusanganisa. Ita shuwa kuti tembiricha yemvura iri pasi pe25°C.
Zvishoma nezvishoma wedzera methylcellulose: Zvishoma nezvishoma dururira methylcellulose poda mumvura inotonhora, uchikurudzira uchidira. Sezvo methylcellulose inowanzoita clump, kuiwedzera zvakananga kumvura kunogona kuumba mapundu, zvichikanganisa kunyange kupararira. Naizvozvo, iyo yekumhanyisa yekuwedzera inoda kunyatsodzorwa kudzivirira kuwedzera huwandu hukuru hwehupfu ipapo.
Sanganisa zvakanaka: Shandisa musanganisi pane yepakati kana yakaderera kumhanya kuparadzira zvizere methylcellulose mumvura. Nguva yekusimudzira zvinoenderana neinodiwa yekupedzisira mhinduro viscosity uye rudzi rwemidziyo, uye kazhinji inotora 5-30 maminetsi. Iva nechokwadi kuti hapana zviputi kana zviputi zvehupfu.
Kuzvimba: Paunenge uchikurudzira, methylcellulose inotora mvura zvishoma nezvishoma uye ichizvimba, ichigadzira colloidal solution. Izvi zvinogona kutora nguva, zvichienderana nerudzi uye huwandu hwemethylcellulose inoshandiswa. Yakakwira viscosity methylcellulose inotora nguva yakareba.
Rega tigare kuti tikure: Mushure mekukurudzira kwapera, zviri nani kurega musanganiswa ugare kwemaawa mashoma kana husiku hwese kuti uve nechokwadi chekuti methylcellulose yanyungudika zvachose uye yakazvimba zvizere. Izvi zvinogona kuwedzera kuvandudza homogeneity yemhinduro.
Nzira 2: Nzira mbiri dzemvura inopisa uye inotonhora
Iyi nzira yakakodzera kune yakanyanya viscous methylcellulose iyo yakaoma kuparadzira zvakananga mumvura inotonhora.
Mvura inopisa premix: Pisa chikamu chemvura kusvika ku70-80 ° C, wobva wakurumidza kunyura mumvura inopisa uye uwedzere methylcellulose. Panguva ino, nekuda kwekupisa kwakanyanya, methylcellulose ichawedzera nekukurumidza asi haizonyungudika zvachose.
Dilution yemvura inotonhora: Paunenge uchienderera mberi nekukuchidzira mugaba wetembiricha yakakwira, zvishoma nezvishoma wedzera mvura inotonhora yasara kusvika tembiricha yadzika kusvika kune yakajairika tembiricha kana pasi pe25°C. Nenzira iyi, iyo yakazvimba methylcellulose inonyungudika mumvura inotonhora uye inogadzira yakagadzikana colloidal mhinduro.
Kukurudzira nekurega kumira: Ramba uchikurudzira mushure mekutonhodza kuti uone kuti mhinduro yacho yakafanana. Musanganiswa wacho unozosiiwa kuti ugare kusvika wanyungudika zvizere.
4. Chengetedzo
Kudzora tembiricha: Kunyungudika kwemethylcellulose kunonzwa zvakanyanya kune tembiricha. Kazhinji inopararira zvakanaka mumvura inotonhora, asi inogona kugadzira gel isina kuenzana mumvura inopisa. Kuti udzivise mamiriro ezvinhu aya, zvinowanzokurudzirwa kushandisa nzira yekuparadzira mvura inotonhora kana inopisa uye inotonhora nzira mbiri.
Dzivisa clumping: Sezvo methylcellulose yakanyanya kunyura, kudira huwandu hwakawanda hwehupfu zvakananga mumvura kuchaita kuti pasi riwedzere nekukurumidza uye kuumba masumbu mukati mepakeji. Izvi hazvingokanganisa kuparara kwemhedzisiro, asi zvinogona zvakare kutungamira kune kusaenzana viscosity yechigadzirwa chekupedzisira. Naizvozvo, iva nechokwadi chekuwedzera hupfu zvishoma nezvishoma uye fambisa zvakanaka.
Kumhanyisa kumhanya: Kumhanyisa-kumhanyisa kunogona kuunza nyore huwandu hukuru hwemabhuru, kunyanya mumhinduro dzine yakakwira viscosity. Bubbles ichakanganisa kuita kwekupedzisira. Naizvozvo, kushandisa yakaderera-kumhanyisa kumhanyisa isarudzo iri nani kana iwe uchida kudzora viscosity kana bubble vhoriyamu.
Concentration ye methylcellulose: Iko kuiswa kwemethylcellulose mumvura ine simba guru pakuparara kwayo uye kugadzirisa zvinhu. Kazhinji kutaura, pakudzika kwakadzika (pasi pe1%), mhinduro itete uye iri nyore kumutsa. Pakukwirira kwakanyanya (kupfuura 2%), mhinduro yacho ichava viscous zvakanyanya uye inoda simba rakasimba pakukurudzira.
Nguva yakamira: Panguva yekugadzirira methylcellulose mhinduro, nguva yekumira yakakosha. Izvi hazvingobvumiri iyo methylcellulose kunyungudika zvachose, asi zvakare inobatsira mabhubhu mumhinduro kuti anyangare zvakajairika, kudzivirira matambudziko ebubble mumashandisirwo anotevera.
5. Unyanzvi hunokosha mukushandisa
Muchikafu chekudya, methylcellulose inowanzoshandiswa kugadzira thickeners, stabilizers kana colloids, zvakadai se ice cream, chingwa, zvinwiwa, nezvimwewo. Muzvikumbiro izvi, danho rekusanganiswa remethylcellulose nemvura inobata zvakananga muromo uye kugadzirwa kwechigadzirwa chekupedzisira. Huwandu hwekushandiswa kwegiredhi rekudya methylcellulose kazhinji idiki, uye kutarisisa kwakanyanya kunoda kubhadharwa pakuyera kwakaringana uye zvishoma nezvishoma kuwedzera.
Mundima yemishonga, methylcellulose inowanzoshandiswa sechinhu chinoparadzana chemapiritsi kana semutakuri wezvinodhaka. Muchiitiko ichi, kugadzirira zvinodhaka kunoda yakanyanya mhinduro homogeneity uye kugadzikana, saka zvinokurudzirwa kudzora yekupedzisira chigadzirwa chemhando nekuwedzera zvishoma nezvishoma viscosity uye optimizing inomutsa mamiriro.
Kusanganisa methylcellulose nemvura inzira inoda moyo murefu uye hunyanzvi. Nekudzora tembiricha yemvura, kurongeka kwekuwedzera uye kukurumidza kumhanyisa, yunifomu uye yakagadzikana methylcellulose mhinduro inogona kuwanikwa. Ingave iri nzira yekuparadzira mvura inotonhora kana inopisa uye inotonhora nzira mbiri, kiyi ndeyekudzivisa kuungana kwehupfu uye kuve nechokwadi chekuzvimba kwakakwana uye kuzorora.
