Isticmaalka
Pentaerythritol waxaa inta badan loo isticmaalaa warshadaha dahaarka. Waxaa loo isticmaali karaa in lagu sameeyo dahaarka resin alkyd, kaas oo hagaajin kara adkaanta, dhalaalka iyo adkeysiga filimka dahaarka. Waxaa sidoo kale loo isticmaalaa sidii walxo ceeriin ah oo loogu talagalay esters-ka rosin ee looga baahan yahay rinjiga, varnishes iyo khadadka daabacaadda, waxaana loo isticmaali karaa in lagu sameeyo saliidaha qalajinta, dahaarka qiiqaya iyo saliidaha duulista. Intaa waxaa dheer, waxaa sidoo kale loo isticmaalaa soo saarista daawada, sunta cayayaanka iyo alaabada kale. Molecule-ka pentaerythritol wuxuu ka kooban yahay afar kooxood oo hydroxymethyl ah oo u dhigma wuxuuna leeyahay heer sare oo isku dheelitiran. Sidaa darteed, waxaa badanaa loo isticmaalaa sidii walxo ceeriin ah oo loogu talagalay diyaarinta isku-dhafka polyfunctional. Nitrification-keeda wuxuu soo saari karaa pentaerythritol tetranitrate, kaas oo ah qarax xooggan; esterification wuxuu heli karaa pentaerythritol triacrylate, kaas oo loo isticmaalo dahaarka. Waxa kale oo loo isticmaali karaa sidii dab-celiye loogu talagalay dhejisyada. Marka lagu daro ammonium polyphosphate, dab-celiye iftiin leh ayaa la heli karaa. Waxa kale oo loo isticmaalaa sidii wakiil isku xidha polyurethane si loo bixiyo silsilado laamo ah oo ku jira polyurethane.
