Methylcellulose yakajairika cellulose derivative inoshandiswa zvakanyanya mumishonga, chikafu uye indasitiri. Iyo polymer inonyungudika nemvura inonyanya kugadzirwa neakasikwa chirimwa cellulose nekugadziriswa kwemakemikari, uye ine akawanda akasiyana zvimiro, zvakaita sekukora, gelling, kumiswa, kugadzira firimu uye kuchengetedza mvura.
Hunhu uye mashandisirwo emethylcellulose
Thickener uye gelling agent: Muindasitiri yezvekudya, methylcellulose inowanzoshandiswa seyakakora uye gelling agent kubatsira kuvandudza magadzirirwo uye kuravira kwechigadzirwa. Semuenzaniso, mune zvigadzirwa senge ice cream, jamu uye saladhi kupfeka, methylcellulose inogona kupa viscosity yakanaka uye inovandudza kugadzikana kwechigadzirwa.
Vatakuri vezvinodhaka uye vabatsiri: Muindasitiri yemishonga, methylcellulose inowanzoshandiswa sechinhu chinobvisa zvinodhaka, senge binder uye filler yemapiritsi. Inogonawo kushandiswa semushonga unosimudzira-kuburitswa kudzora chiyero chekuburitswa kwemushonga uye kuve nechokwadi kugadzikana uye kusimba kweiyo dhizaini mhedzisiro.
Kushandisa muzvivakwa zvekuvaka: Mumunda wezvivakwa zvekuvaka, methylcellulose inoshandiswa seyakakora uye inochengetedza mvura musimende, gypsum uye machira kuvandudza mashandiro ekuvaka uye kusimba kwechinhu.
Musiyano pakati pemethylcellulose uye antifoaming agents
Antifoaming agents ikirasi yemakemikari anoshandiswa kudzvanya kana kubvisa mabhubhu muzvinwiwa, uye anowanzo kuwanikwa mukugadzira chikafu, mishonga yemishonga, zvizorwa, kugadzira mapepa, makemikari, uye kurapwa kwemvura. Antifoaming agents anowanzo shanda nekudzikisa kusimba kwepamusoro pemvura kudzivirira kuumbwa kwefuro, kana nekusimudzira kukurumidza kudonha kwefuro rakaumbwa. Zvakajairwa antifoaming agents zvinosanganisira silicone oiri, polyethers, fatty acid esters, uye zvimwe zvimedu zvakasimba, sesilicon dioxide.
Nekudaro, methylcellulose haisi antifoaming mumiriri mune zvakasikwa. Kunyange zvazvo methylcellulose inogona kugadzira viscous mhinduro kana yakanyungudutswa mumvura, uye viscosity yemhinduro iyi inogona kukanganisa kuumbwa kwefuro mune dzimwe nguva, haina nzvimbo inoshanda yeakajairika antifoaming agents. Mune mamwe mazwi, basa guru re methylcellulose nderekuti inoshanda seyakakora, gelling agent, suspending agent, nezvimwewo, pane kunyatso shandiswa kudzvanya kana kubvisa furo.
Zvinogoneka kuvhiringidzika uye zviitiko zvakakosha
Kunyangwe methylcellulose isiri antifoaming agent, mune mamwe magadzirirwo chaiwo kana zvigadzirwa, inogona kukanganisa zvisina kunanga maitiro efuro nekuda kwekukora kwayo uye maitiro ekugadzirisa. Semuenzaniso, mune zvimwe zvekudya kana zvinodhaka zvinogadzirwa, iyo yakakwira viscosity yemethylcellulose inogona kudzikamisa kuumbwa kwemabhuru kana kuita kuti mabhuru akaumbwa aparare nekukurumidza. Zvisinei, chiitiko ichi hachibvumiri kuti chionekwe sechigadziro chekudzivirira furo nokuti nzira yayo huru yekuita yakasiyana zvikuru nemakemikari uye maitiro ekuita kweanopikisa.
Methylcellulose inoshandiswa zvakanyanya selulosi kubva kune akawanda mabasa, asi haina kutorwa seantifoaming agent. Kunyangwe zvingave nemhedzisiro pamaitiro ekupupa mune mamwe mamiriro chaiwo, izvi hazviunze kushandiswa kwayo kukuru kana nzira yekuita. Antifoaming agents anowanzo kuve neaya chaiwo chiitiko chepamusoro uye furo kutonga masimba, nepo methylcellulose inonyanya kushandiswa kukora, gelling, kumiswa uye kuchengetedza mvura. Naizvozvo, kana uchishandisa methylcellulose, kana yakajeka antifoaming mhedzisiro ichidikanwa, yakakosha antifoaming agent inofanirwa kusarudzwa kuti ishandiswe pamwe chete.
