Kagwiritsidwe Ntchito
4,4'-Diamino-3,3'-dichlorodiphenylmethane (MOCA) ndi mankhwala achilengedwe, ndipo njira zake zazikulu zogwiritsira ntchito ndi izi:
- Kupanga Zipangizo za Polyurethane: MOCA ndi chowonjezera unyolo chofunikira cha ma elastomer a polyurethane. Pakupanga polyurethane, ma prepolymer a isocyanate ayenera kuchitapo kanthu ndi ma extenders a unyolo kuti apange ma polima a polyurethane okhala ndi mamolekyulu ambiri. MOCA ili ndi reactivity yayikulu ndi ma isocyanate, zomwe zimatha kukulitsa bwino unyolo wa mamolekyu a polyurethane ndikuwonjezera kuuma, mphamvu, kukana kuvala, kukana kung'ambika ndi zina mwazinthuzo. Imagwiritsidwa ntchito kwambiri popanga zinthu za polyurethane elastomer zokhala ndi katundu wambiri, monga mbale zosiyidwa, ma roller a rabara, zisindikizo, ndi zina zotero zomwe zimagwiritsidwa ntchito m'mafakitale monga migodi, zitsulo, ndi mafuta. Zogulitsazi ziyenera kukhala ndi kukana kuvala bwino komanso mphamvu zamakanika.
- Chothandizira Kuchiritsa Ma Resin a Epoxy: MOCA ingagwiritsidwe ntchito ngati chothandizira kuchiritsa ma resin a epoxy. Imadutsa mu mgwirizano wolumikizana ndi ma resin a epoxy kuti ipange kapangidwe ka netiweki ya magawo atatu, motero imachiritsa ma resin a epoxy. Ma resin a epoxy ochiritsidwa ali ndi mphamvu zabwino zamakaniko, kukana dzimbiri kwa mankhwala, komanso kukana kutentha. Nthawi zambiri amagwiritsidwa ntchito popanga zinthu zina za epoxy zomwe zimafunikira magwiridwe antchito apamwamba, monga m'magawo azinthu zamagetsi zopangira miphika ndi zokutira pansi. Zipangizo zamagetsi zopangira miphika ziyenera kuteteza zigawo zamagetsi zamkati kuchokera ku chilengedwe chakunja. Resin ya epoxy yochiritsidwa ndi MOCA ingapereke chitetezo chabwino komanso chitetezo chamakina. Zophimba pansi za epoxy ziyenera kukhala ndi mphamvu monga kukana kukalamba ndi kukana dzimbiri kuti zikwaniritse zofunikira zogwiritsidwa ntchito m'malo monga malo ochitira mafakitale ndi malo oimika magalimoto.
Kulongedza ndi Kutumiza
25KG/thumba kapena malinga ndi zomwe makasitomala amafuna.
Kutumiza: Mitundu 6.1 ya katundu woopsa ndipo akhoza kutumizidwa kudzera panyanja.
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.
