Phenolic khoom ceev

Qhov ntom ntawm cov khoom siv phenolic
Qhov ntom ntawm cov ntaub ntawv phenolic feem ntau yog nyob ntawm lawv daim ntawv thov tshwj xeeb. Qhov ceev ntawm phenolic foam insulation board feem ntau yog qis dua 100 kg / m3, thiab tuaj yeem ncav cuag li 50 kg / m3. Cov yam ntxwv no ua rau phenolic rwb thaiv tsev board muaj kev laus tiv thaiv zoo, thiab tuaj yeem txo qhov hnyav ntawm lub tsev, txo cov load ntawm lub tsev, thiab txo tus nqi ntawm cov qauv. Tib lub sijhawm, kev tsim kho yog yooj yim thiab ceev, uas tuaj yeem txhim kho kev ua haujlwm zoo1. Ntawm qhov tod tes, 201 phenolic resin yog cov kua liab-xim av nrog qhov ntom ntawm 1.20 thiab 1.30 g / cm3 thiab cov ntsiab lus ntawm 45% mus rau 55%. Cov resin no yog soluble hauv ethanol thiab nws cov viscosity tsis tshaj 40 mPa·s2 ntawm 25 degree. Txawm hais tias ob qho tib si yog cov khoom siv phenolic, lawv qhov ntom ntom sib txawv vim lawv cov ntawv thov sib txawv. Phenyico ua npuas ncauj rwb thaiv tsev board muaj qhov qis dua vim nws cov qauv sib tw thiab haum rau kev siv ua cov khoom siv rwb thaiv tsev; thaum 201 phenolic resin muaj qhov ntom ntom dua vim nws cov ntaub ntawv ua kua thiab cov ntsiab lus siab dua, thiab feem ntau yog siv los tsim cov txheej txheem tiv thaiv corrosion thiab cov nplaum.
