Cov Ntawv Thov
1. PHEM HAUV INFID-LAX SCRATION
PhenolphatEin yog ib qho ntawm feem ntau dav siv cov kua qaub-paus-cov ntsuas hauv chaw soj ntsuam:
Xim hloov ntau yam: pH 8.2 (tsis muaj xim) rau 10.0 (qaim liab)
Feem ntau siv nyob rau hauv ib qho kev ntsuam xyuas alkalinity, cov npe, thiab dej hardness tsom
Siv nyob rau hauv cov chaw kawm txuj ci los ua kom pom cov kua qaub-hauv paus
2. Kev Tshawb Fawb Kev Ntsuas
Muaj nuj nqi raws li kev ua txhaum nyob rau ntau yam tshuaj lom neeg tshuaj xyuas
Ua haujlwm hauv cov lus sib txuas ua haujlwm nrog EDTA los txiav txim siab cov hlau ion ntau
3. Kev kho mob siv (keeb kwm)
Laxative siv (yav dhau los): ib zaug dav siv raws li kev tshaj tawm-cov txee kev txhawb zog vim nws lub peev xwm los txhawb txoj hnyuv txav
Tam sim no ntau txiav tawm rau cov phiaj xwm tshuaj muaj ntau lub teb chaws vim tias muaj kev txhawj xeeb txog cov tsiaj ntev
4. Kev Tshawb Fawb Kev Tshawb Fawb
Siv nyob rau hauv Latent ntshav nrhiav kom tau (phenolphhatale tes kuaj lossis kuaj cov meyer):
Reacts nrog hemoglobin nyob rau hauv cov ntshav nyob rau hauv muaj ntawm hydrogen peroxide, tsim cov xim liab
Muaj nqis rau kev ua ntej rau kev kuaj pom ntawm qhov kev ua txhaum scenes
5. Polymer thiab Plastics Kev Lag Luam
Siv raws li kev tivthaiv hauv pH-rhiab polymers, tshwj xeeb tshaj yog nyob rau hauv hydrogels thiab cov ntaub ntawv ntse
Ua raws li tus qauv sib txawv hauv polymer tsis zoo thiab kev sib cais kev kawm
Cov txiaj ntsig
Cov kev hloov pauv xim tau hloov: nws cov ntse thiab qhov sib txawv xim ua rau nws qhov ntsuas uas nyiam dua rau ntau lub sijhawm.
Stability: phenolphhatalein yog ruaj khov nyob rau hauv daim foos qhuav thiab muaj lub teeb ntev lub neej nyob rau hauv cov neeg muaj cai cia.
Qhov rhiab: kuaj pom txawm tias cov kev hloov me me hauv pH, tshwj xeeb hauv ib puag ncig ib puag ncig.
Ntau tus neeg ua haujlwm raws cai: nws pabcuam rau hauv kev kawm, kev kho mob, ua rau muaj kev lag luam, ua rau pom cov versatility.
Tag
Phenolphhalealein (CAS 77-09-8) yog cov cuab yeej siv tshuaj classic thiab muaj hwj chim siv nrog cov ntawv thov kev ntsuas dav dav los ntawm kev ntsuas tshuaj thiab kev kawm rau cov tshuaj ntsuam thiab cov ntaub ntawv tshawb fawb. Thaum nws siv raws li kev ntsuas ntawm kev ntsuas yog vim muaj kev txhawj xeeb txog kev nyab xeeb, nws tseem nyob hauv cov kua qaub-paps, kev tshawb nrhiav ntshav, thiab kev tshawb fawb polymer. Nws muaj zog Colorimetric cov khoom thiab cov lus sau ua zoo-ua kom ntseeg tau tias nws tau txuas ntxiv rau hauv chaw soj nstuam thiab kev tshawb fawb.
