Methyl cellulose ndiyo chidimbu che sodium carboxymethyl cellulose. Inonyanya kushandiswa muzvokudya, kuvaka, mishonga, ceramics, mabhatiri, migodhi, machira, mapepa, kushambidza, zuva nezuva kemikari mazino emazino, machira kudhinda uye dhayi, kuchera mafuta, nezvimwewo mukati memunda. Basa guru nderokuita semukobvu, kuchengetedza mvura, binder, lubricant, suspending agent, emulsifier, biological product carrier, tablet matrix, nezvimwewo. Ko methyl cellulose inofanira kuenzaniswa sei panguva yekushandiswa?
1. Methylcellulose pachayo ipfu yakachena yakaoma, iyo isingagoni kushandiswa zvakananga mumhizha. Inoda kutanga yanyungudutswa mumvura kuti igadzire inoonekera viscous glue isati yasanganiswa nedhaka uye yozoshandiswa kune imwe interface kurapwa, sekunamira mataira.
2. Chii chinonzi methyl cellulose? Powder: mvura inoda kugadziriswa panguva zvichienderana nechiyero che1: 150-200, uye yobva yabvongodzwa, uchiwedzera PMC poda yakaoma paunenge uchikurudzira, uye inogona kushandiswa mushure mekushandisa kweawa imwe.
3. Kana methyl cellulose ichishandiswa kurapa kongiri, chiyero cheglue chinoda kutevedzera → glue: simende = 1:2.
4. Kana methyl cellulose ikashandiswa sedhaka resimende kuramba kutsemuka, glue reshiyo inoda kuteverwa → guruu: simende: jecha = 1:3:6.
Isu tinofanirwa kutarisisa kune mamwe matambudziko kana uchishandisa methyl cellulose:
1. Usati washandisa methyl cellulose zviri pamutemo, unofanira kutanga watarisa zvakatemwa nemhando. Mhando dzakasiyana dzinoshandisa nzira dzakasiyana: apo pH> 10 kana <5, viscosity yeglue inenge yakaderera. Kuita ndiko kwakanyanya kugadzikana kana pH = 7, uye viscosity ichasimuka nekukurumidza kana tembiricha iri pasi pe20 ° C; apo kutonhora kuri pamusoro pe80 ° C, iyo colloid ichave yakasvibiswa mushure mekupisa kwenguva refu, asi viscosity ichadonha zvakanyanya.
2. Methyl cellulose inogona kugadzirirwa nemvura inotonhora kana mvura inopisa maererano nechiyero chakatarwa. Paunenge uchigadzirira, unoda kuwedzera mvura paunenge uchikurudzira. Rangarira kuwedzera mvura yese uye PMC yakaoma hupfu panguva imwe chete. Zvakakosha kucherechedza kuti chigadziko chinoda kusungirirwa chinofanira kucheneswa pachine nguva, uye imwe tsvina, tsvina yemafuta, uye mashizha akasununguka anofanira kugadziriswa nenguva.
