Daim ntawv thov

Polyvinylpyrrolidone yog dav siv nyob rau hauv lub teb ntawm cov tshuaj thiab yog ib tug ntawm peb lub tshiab tshuaj excipients tawm tswv yim thoob ntiaj teb. Feem ntau siv cov nplaum nplaum yog cov ntsiav tshuaj thiab granules. Nws kuj tseem siv tau los ua kev pab cuam rau cov tshuaj ntsiav, detoxification thiab lubricant rau qhov muag tshuaj, ib co-solvent rau kev txhaj tshuaj, dispersant rau kua npaj, thiab ib tug stabilizer rau enzymes thiab tshav kub-sensitive tshuaj. Povidone kuj tseem tuaj yeem ua ke nrog iodine povidone iodine (PVP-I) tshuaj tua kab mob. Hauv kev tiv thaiv lo ntsiab muag, PVP yog siv los ua ib feem ntawm cov lo ntsiab muag los ua kom lawv cov hydrophilicity. PVP tseem tuaj yeem siv los ua cov tshuaj tiv thaiv cryogenic hauv tshuaj.
