Lub npe tshuaj: Polyhexamethylene Guanidine Hydrochloride (PHMG). Molecular Formula: (C8H17N5)n·xHCl, qhov twg n=12–16. CAS Nr .: 27083-27-8 (EU), 32289-58-0 (USA). Cov tsos mob: tsis muaj xim rau cov kua daj daj, lossis cov hmoov dawb / crystalline khoom. Lub cev tsis muaj zog: Cov ntsiab lus ntawm cov khoom (kua daim ntawv) 19.0%–21.0%; pH ntawm 1% aqueous tov 4.0-7.0; density approx . 1.04 g/mL; decomposition kub siab tshaj los yog sib npaug rau 300 degree.
1. Ua tiav hauv dej; miscible nrog polar solvents xws li ethanol thiab ethylene glycol.
2. Cov tshuaj aqueous tsis muaj xim thiab tsis muaj ntxhiab. Cov kev tshawb fawb tshuaj toxicological qhia tias qhov ncauj tsis tshua muaj toxicity (mob qhov ncauj LD50 hauv cov nas> 5000 mg / kg) thiab tsis ua rau tawv nqaij lossis qhov muag [4]. Txawm li cas los xij, kev nqus pa (piv txwv li, hauv daim ntawv aerosol) tuaj yeem ua rau muaj kev pheej hmoo ntawm kev ua pa toxicity.
3. Tsis yog-flammable thiab non-explosive; qhia tau zoo heev stability thiab tsis yog -volatility. Nws tseem nyob ruaj khov nyob rau hauv pH ntau ntawm 1-11, nrog rau lub neej txee ntawm kwv yees li ob xyoos ntawm chav tsev kub.
4. Muaj cov kab mob bactericidal uas dav -spectrum, muaj txiaj ntsig zoo, thiab muab cov kab mob bacteriostatic ntev ntev. Nws cov tshuaj tiv thaiv kab mob yog ua raws li cov pab pawg guanidine hauv cov polymer, uas tau txais ib qho txiaj ntsig zoo thaum tawg hauv dej. Cov pab pawg tau txais txiaj ntsig zoo no khi los ntawm electrostatic adsorption mus rau qhov tsis zoo ntawm cov cell membranes ntawm cov kab mob, yog li inhibiting cell division thiab ua rau microbial tuag. Hom kev ua no suav nrog kev ua kom tsis muaj menyuam lub cev, ua rau txoj kev loj hlob ntawm microbial tsis zoo.
5. Tsis yog -corrosive rau ntau yam ntaub ntawv.
6. Tsis yog -corrosive hauv xwm.
7. Pub dawb los ntawm cov tshuaj phem xws li aldehydes, iodine, thiab cov tshuaj chlorine.
