Kagwiritsidwe Ntchito
Kapangidwe kake ka MXDA kamatsimikizira kuti kali ndi zinthu zosiyanasiyana zabwino kwambiri zakuthupi ndi zamakemikolo, kotero kamagwiritsidwa ntchito kwambiri. MXDA ndi ma cyclic hydride ake angagwiritsidwe ntchito ngati zinthu zochiritsira ma epoxy resins, okhala ndi mphamvu yabwino kwambiri yochiritsira kutentha kwa chipinda, kukana kutentha bwino, kukana madzi, komanso kukana dzimbiri kwa mankhwala. Kuphatikiza apo, amatha kupanga ma resins owonekera bwino komanso omalizidwa bwino kwambiri okhala ndi kukhuthala kochepa komanso magwiridwe antchito abwino. Nthawi yomweyo, MXDA ndi chinthu chofunikira kwambiri cha mankhwala, chomwe chingapangitse ma polyamides ndi ma dibasic acid, ndipo chingapangitse m-xylene diisocyanate, monomer ya polyurethane. Ma hydride ake a benzene ring angagwiritsidwenso ntchito kupanga ma diisocyanates. Pakadali pano, yagwiritsidwa ntchito popanga zinthu zolumikizira mphira, mankhwala ophera tizilombo, zolimbitsa ulusi, ma surfactants, ndi zina zotero.
1,3-Benzenedimethylamine imagwiritsidwa ntchito makamaka popanga zinthu zochiritsira utomoni wa epoxy zomwe zimapirira kutentha, sizimayambitsa poizoni, zoyenera kupangidwa pansi pa madzi, komanso zimatha kuchira mwachangu zikatenthedwa. Imagwira ntchito ngati zopangira ma polyurethane resin ndi ma epoxy resin opangidwa, ndipo imagwiritsidwanso ntchito m'magawo othandizira a rabara, mapulasitiki osavuta kuwala, mankhwala ophera tizilombo, zokutira, zinthu zopangidwa ndi nayiloni, zinthu zomaliza ulusi, zoletsa dzimbiri, zinthu zothira mafuta, mafuta odzola, kukonza mapepala, ndi zina zotero.
Amagwiritsidwa ntchito pokonzekera zinthu zoyeretsera utomoni wa epoxy, mapulasitiki otha kuwala, zinthu zothandizira za rabara, ma resini a polyurethane, zokutira, ndi zina zotero. Amagwiritsidwa ntchito makamaka popanga zinthu zoyeretsera utomoni wa epoxy zomwe zimateteza kutentha, sizimayambitsa poizoni, zoyenera kumangidwa pansi pa madzi, ndipo zimatha kuchira mwachangu zikatenthedwa. Amagwiritsidwanso ntchito ngati zinthu zopangira ma resini a polyurethane ndi ma resini a epoxy opangidwa, ndipo amagwiritsidwanso ntchito m'magawo othandizira a rabara, mapulasitiki otha kuwala, mankhwala ophera tizilombo, zokutira, zinthu za nayiloni, zinthu zomaliza ulusi, zoletsa dzimbiri, zinthu zothira mafuta, mafuta odzola, kukonza mapepala, ndi zina zotero.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
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.
