Kev siv
Pentaerythritol yog siv dav hauv kev lag luam coatings rau kev tsim cov alkyd resins. Cov resins no yog ib qho tseem ceeb ntawm ntau cov txheej txheem, muab cov kav ntev, adhesion thiab corrosion kuj. Tsis tas li ntawd, pentaerythritol kuj tau siv dav hauv kev sib txuas ntawm cov roj nplua nyeem siab heev los muab kev ua tau zoo thiab kev tiv thaiv ntev ntev rau cov tshuab thiab tsheb.
Tsis tas li ntawd, pentaerythritol yog cov khoom tseem ceeb hauv kev tsim cov plasticizers thiab surfactants. Plasticizers txhim kho qhov yooj thiab ua haujlwm ntawm cov yas, ua rau lawv yog ib feem tseem ceeb ntawm ntau yam kev siv. Ntawm qhov tod tes, emulsifying thiab foaming zog ntawm surfactants yog ib qho tseem ceeb thiab siv hauv kev lag luam xws li kev tu tus kheej, tu thiab kev ua liaj ua teb.
Dhau li ntawm nws lub luag haujlwm hauv ntau daim ntawv thov kev lag luam, pentaerythritol kuj tseem siv rau hauv kev sib txuas ntawm cov tshuaj thiab cov khoom tawg. Nws cov khoom siv tshuaj lom neeg tshwj xeeb ua rau nws muaj txiaj ntsig zoo tshaj plaws hauv kev tsim tshuaj, pab ua kom muaj txiaj ntsig thiab ruaj khov ntawm qee cov qauv. Tsis tas li ntawd, cov khoom flammable ntawm pentaerythritol ua rau nws muaj qhov tseem ceeb hauv kev tsim cov khoom tawg, ua kom muaj kev ruaj ntseg thiab muaj zog ntawm cov ntaub ntawv no.
Zuag qhia tag nrho, pentaerythritol yog ib qho tseem ceeb heev organic compound uas muaj ntau yam kev siv hauv kev lag luam sib txawv. Nws versatility thiab tshwj xeeb chemistry ua rau nws ib tug nrov muaj nyob rau hauv lub tsim ntawm alkyd resins, advanced lubricants, plasticizers, surfactants, tshuaj thiab explosives. Nrog nws daim ntawv dawb crystalline hmoov, nws tau yooj yim muab tso rau hauv ntau yam txheej txheem, muab kev ua tau zoo thiab kev ntseeg siab. Tso siab rau pentaerythritol los txhawb koj cov khoom thiab txhim kho lawv cov txiaj ntsig.
