Focus on Cellulose ethers

Nzira yekusarudza yakakodzera hydroxypropyl methylcellulose yemukati uye kunze kwemadziro putty

Nzira yekusarudza HPMC yakarurama

1. Maererano nemuenzaniso: Maererano nemaitiro akasiyana-siyana emaputi akasiyana-siyana, maitiro e viscosity yehydroxypropyl methylcellulose uye methylcellulose akasiyanawo. Vanoshandiswa kubva ku40,000 kusvika ku100,000. Panguva imwecheteyo, iyo fiber Vegetarian ether haigoni kutsiva basa remamwe mabhanhire, kuwedzera cellulose ether hazvirevi kuti zvigadzirwa zvezvimwe zvisungo zvinogona kuderedzwa.

2. Unoda mvura inotonhora inorasika cellulose ether: Cellulose ether (kusanganisira hydroxypropyl methylcellulose uye methylcellulose) is surfactant ine high viscosity mushure mekuparadzwa. Ndicho chikonzero chechimiro ichi kuti kana yakajairwa cellulose ether yakawedzerwa kumvura, zviri nyore kugadzira bhora, uye kunze kwebhora rakanyungudutswa kuita mushonga wakanyanya, uye mukati wakaputirwa, uye zvakaoma. kuti mvura ipinde mukati, zvichiita kuti isanyungudika zvakanaka. . Iyo yepamusoro-yakagadziriswa cellulose ether (iyo inogona kunonoka kupera) haizove seizvi, uye inogona kuparadzirwa zvakanaka mumvura inotonhora (kunonoka kupera, uye zvishoma nezvishoma kunyungudika mushure mekupararira). Icho chisarudzo chakanaka kunzwisisa kusiyana kwepamusoro.

1. Kune yakaoma-yakavhenganiswa mukati uye kunze kwemadziro emadziro putty, nokuti cellulose ether yakanyatsoparadzirwa muzvinhu panguva yekuoma-kusanganiswa kwekugadzirisa, hapazovi nekubatana. Naizvozvo, zvinokurudzirwa kushandisa zvakajairika mhando (isina-inotonhora mvura yekuparadzira mhando), nekuti chiyero chekunyungudika chemhando yakajairika inokurumidza kupfuura yemhando yemvura inotonhora yekuparadzira, iyo inopfupisa nguva yekumirira kubva pakusanganisa slurry kusvika pakuvaka.

2. Nekugadzirira kweputty inonyungudutsa zvakananga cellulose ether (kusanganisira hydroxypropyl methylcellulose uye methylcellulose) mumvura uye kuisanganisa nezvimwe zvinhu, zvinokurudzirwa kushandisa mvura inotonhora yekupararira rudzi rwecellulose ether. Iyo yepamusoro-yakagadziriswa cellulose ether inogona kunyatsoparadzirwa mumvura inotonhora uye yakanyungudutswa (inogona kunonoka kupera)
