Kagwiritsidwe Ntchito
Pentaerythritol imagwiritsidwa ntchito kwambiri mumakampani opanga utoto. Itha kugwiritsidwa ntchito popanga utoto wa alkyd resin, womwe ungathandize kuuma, kunyezimira, komanso kulimba kwa filimu yophimba utoto. Imagwiritsidwanso ntchito ngati zinthu zopangira ma rosin esters ofunikira pa utoto, ma varnish ndi inki yosindikizira, ndipo ingagwiritsidwe ntchito popanga mafuta owuma, zophimba zotentha komanso mafuta opaka ndege. Kuphatikiza apo, imagwiritsidwanso ntchito popanga mankhwala, mankhwala ophera tizilombo ndi zinthu zina. Molekyulu ya pentaerythritol ili ndi magulu anayi ofanana a hydroxymethyl ndipo ili ndi mulingo wofanana kwambiri. Chifukwa chake, nthawi zambiri imagwiritsidwa ntchito ngati zinthu zopangira zinthu zosiyanasiyana. Nitrification yake imatha kupanga pentaerythritol tetranitrate, yomwe ndi yophulika kwambiri; esterification imatha kupeza pentaerythritol triacrylate, yomwe imagwiritsidwa ntchito ngati utoto. Itha kugwiritsidwanso ntchito ngati choletsa moto cha zomatira. Ikaphatikizidwa ndi ammonium polyphosphate, choletsa moto cha intumescent chingapezeke. Imagwiritsidwanso ntchito ngati cholumikizira cha polyurethane kuti ipereke unyolo wolumikizana mu polyurethane.
Kulongedza ndi Kutumiza
Kulongedza: 25/kg,Mapepala opangidwa ndi pulasitiki kapena matumba a mapepala opangidwa ndi kraft kapena malinga ndi zomwe makasitomala akufuna.
Kutumiza: ndi mankhwala wamba ndipo amatha kutumizidwa ndi sitima, nyanja ndi mpweya.
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
