Cov yam ntxwv tseem ceeb ntawm pentaerythritol nyob rau hauv muaj plaub pawg hydroxyl nyob rau hauv nws cov molecule; Cov pab pawg no muaj qhov ua kom muaj zog thiab tuaj yeem ua rau muaj ntau yam sib txuas, xws li carboxylic acids, aldehydes, thiab isocyanates. Vim hais tias ib qho molecule muaj ntau qhov chaw reactive, pentaerythritol ua haujlwm tsis yog raws li tus qauv polyol hauv cov tshuaj tiv thaiv kab mob tab sis kuj yog ib qho txuas uas txuas cov saw hlau sib txawv, ua kom yooj yim tsim cov ceg ntoo lossis ntoo khaub lig- txuas cov qauv. Qhov kev ua haujlwm siab no txawv ntawm pentaerythritol los ntawm diols xws li ethylene glycol thiab propylene glycol.
Hauv kev tsim cov alkyd resins, pentaerythritol feem ntau dhau los ua cov tshuaj tiv thaiv esterification cuam tshuam nrog nws pawg hydroxyl thiab fatty acids lossis polyacids. Thaum lub sij hawm cov tshuaj tiv thaiv, condensation tshwm sim ntawm cov hydroxyl thiab carboxyl pawg nrog tshem tawm cov dej; Raws li cov tshuaj tiv thaiv zoo zuj zus, monomers txuas ua ke los tsim cov polymer loj dua. Nws plaub pawg hydroxyl muab ntau cov ntsiab lus sib txuas, qhia txog qib ntawm cov ceg ntoo thiab ntoo khaub lig-txoj kev muaj peev xwm txuas mus rau qhov kawg resin. Kho tus nqi ntawm pentaerythritol siv tso cai rau kev hloov kho ntawm cov khoom xws li hardness, yooj, dej tsis kam, thiab huab cua.
Nws cov txheej txheem ntawm kev ua haujlwm hauv nplaim taws- cov khoom siv retardant txawv. Pentaerythritol muaj cov pa roj carbon ntau thiab ntau pawg hydroxyl, ua kom nws koom nrog hauv cov txheej txheem xws li lub cev qhuav dej thiab charring thaum raug tshav kub. Thaum siv ua ke nrog cov kua qaub thiab lwm cov nplaim taws - cov khoom siv retardant, nws txhawb kev tsim cov txheej txheem ntom ntom thaum cua sov. Cov char txheej no coats cov khoom nto, inhibiting tshav kub hloov mus rau sab hauv thiab txwv kev sib cuag ntawm combustible gases thiab oxygen, yog li ua raws li ib tug thermal barrier thiab suppressing combustion. Yog li ntawd, pentaerythritol feem ntau ua hauj lwm raws li ib tug char- tsim tus neeg sawv cev nyob rau hauv intumescent nplaim- retardant systems.
