Hydroxypropyl methylcellulose, inozivikanwawo seHPMC, is nonionic cellulose ether inowanikwa kubva kudonje rakanatswa, yakasikwa polymer zvinhu, kuburikidza neakatevedzana emakemikari maitiro. Ihupfu chena kana kuti yero zvishoma inonyungudika mumvura. Ngatitaurei nezve nzira yekunyungudutsa yehydroxypropyl methylcellulose.
1. Hydroxypropyl methylcellulose inonyanya kushandiswa sekuwedzera kune putty powder, dhaka uye glue. Yakawedzerwa kune simenti dhaka, inogona kushandiswa sechinhu chekuchengetedza mvura uye inononoka kuwedzera kupomba; yakawedzerwa kune putty powder uye glue, inogona kushandiswa sebhainda. Kuti tivandudze kupararira uye kuwedzera nguva yekushanda, tinotora Qingquan Cellulose semuenzaniso wekutsanangura nzira yekuparara kwehydroxypropyl methylcellulose.
2. Ordinary hydroxypropyl methylcellulose inotanga kubvongodzwa uye inoparadzirwa nemvura inopisa, yozowedzerwa nemvura inotonhora, yakavhenganiswa uye inotonhorera kuti iparadze;
Kunyanya: tora 1/5-1/3 yehuwandu hunodiwa hwemvura inopisa, kurunga kusvikira chigadzirwa chawedzera kuzvimba, wobva wawedzera chikamu chasara chemvura inopisa, inogona kunge iri mvura inotonhora kana mvura yechando, uye simbisa tembiricha yakakodzera (10°C) kusvikira yanyungudika zvachose.
3. Organic solvent wetting nzira:
Dispersa hydroxypropyl methylcellulose muorganic solvent kana kuinyorovesa neorganic solvent, wobva wawedzera kana kuwedzera mvura inotonhora kuinyungudutsa zvakanaka. Iyo organic solvent inogona kuva ethanol, ethylene glycol, nezvimwe.
4. Kana agglomeration kana kuputira kukaitika panguva yekuparara, imhaka yekuti kubvongodza hakuna kukwana kana kuti yakajairika modhi inowedzerwa zvakananga kumvura inotonhora. Panguva ino, kurumidzira nekukurumidza.
5. Kana mabhubhu akagadzirwa panguva yekuparara, anogona kusara kwemaawa 2-12 (nguva yakatarwa inobva pakuenderana kwemhinduro) kana kubviswa nekutsvaira, kudzvinyirira, nezvimwewo, kana kuwedzera chiyero chakakodzera che defoaming agent.
Zvekungwaririra
Hydroxypropyl methylcellulose yakakamurwa kuita inononoka-kunyungudika uye nekukasira-kunyungudika marudzi. Instant hydroxypropyl methylcellulose inogona kunyungudika zvakananga mumvura inotonhora.
