MOCA,Chomwe chimadziwikanso kuti 4,4′-Methylenebis (2-chloroaniline), ndi kristalo woyera mpaka wachikasu wopepuka womwe umasintha kukhala wakuda ukatenthedwa. Chosakaniza chosiyanasiyanachi chimakhala chosakanikirana pang'ono ndipo chimasungunuka mu ma ketone ndi ma hydrocarbons onunkhira. Koma chomwe chimasiyanitsa MOCA ndi mitundu yosiyanasiyana ya ntchito zake ndi mawonekedwe ake.
Kapangidwe ka mankhwala:Krustalo wa singano wopepuka mpaka woyera, wotentha mpaka wakuda. Wosasinthasintha pang'ono. Amasungunuka mu ma ketone ndi ma hydrocarbon onunkhira.
MOCA imagwiritsidwa ntchito kwambiri ngati chopangira vulcanizing cha rabara ya polyurethane yopangidwa ndi chitsulo. Kapangidwe kake kogwirizanitsa zinthu kumapangitsa kuti ikhale chisankho chabwino kwambiri chowonjezera mphamvu ndi kulimba kwa zipangizo za rabara. Kuphatikiza apo, MOCA imagwira ntchito ngati chopangira crosslinking cha zokutira ndi zomatira za polyurethane, zomwe zimapangitsa kuti zikhale zolimba komanso zogwira ntchito bwino. Kuphatikiza apo, chopangira ichi chingagwiritsidwe ntchito pochiritsa ma epoxy resins, zomwe zimapangitsa kuti chikhale chofunikira kwambiri m'mafakitale osiyanasiyana.
Kuphatikiza apo, MOCA imagwira ntchito mosiyanasiyana m'njira zosiyanasiyana. MOCA yamadzimadzi ingagwiritsidwe ntchito ngati chotsukira cha polyurethane kutentha kwa chipinda, zomwe zimapangitsa kuti ikhale yosavuta komanso yosinthasintha. Ingagwiritsidwenso ntchito ngati chotsukira cha polyurea popopera, zomwe zimapangitsa kuti ikhale yosavuta kugwiritsa ntchito.
Ubwino ndi ntchito zake：
Ponena za ntchito ya rabara ndi zokutira za polyurethane, kupeza cholumikizira choyenera ndikofunikira kwambiri. Apa ndi pomwe MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) imatenga malo ofunikira. Chifukwa cha mawonekedwe ake apadera komanso ntchito zake zosiyanasiyana, MOCA yakhala yofunika kwambiri m'mafakitale osiyanasiyana.
MOCA imadziwika chifukwa cha mawonekedwe ake oyera mpaka achikasu opepuka, omwe amasanduka akuda akamatenthedwa. Kuphatikiza apo, ili ndi mphamvu zochepa zosakanikirana ndipo imasungunuka mu ma ketone ndi ma hydrocarbons onunkhira. Makhalidwe amenewa amawapangitsa kukhala oyenera kugwiritsidwa ntchito popanga zinthu zosiyanasiyana.
Chimodzi mwa zabwino zazikulu za MOCA ndi ntchito yake ngati chopangira vulcanizing cha rabara ya polyurethane yopangidwa ndi chitsulo. Mwa kulumikiza unyolo wa polima, MOCA imawonjezera mphamvu ndi kulimba kwa rabara. Izi zimatsimikizira kuti chinthu chomaliza chikhoza kupirira mikhalidwe yovuta ndikusunga umphumphu wake kwa nthawi yayitali.
Kuphatikiza apo, MOCA imagwira ntchito ngati cholumikizira chabwino kwambiri cha zokutira ndi zomatira za polyurethane. Imalimbikitsa mgwirizano wa mankhwala pakati pa mamolekyu a polima, zomwe zimapangitsa kuti zokutira ndi zomatira zikhale zogwira ntchito bwino kwambiri. Kaya ndi zokutira zoteteza kapena zomatira zomangira, MOCA imapereka mphamvu ndi kukhazikika kofunikira.
Kuwonjezera pa ntchito zake mu rabara ndi zokutira, MOCA ingagwiritsidwenso ntchito pochiritsa ma epoxy resin. Mwa kuwonjezera pang'ono MOCA, epoxy resin imatha kuyanjana, zomwe zimapangitsa kuti makina ndi kutentha zikhale bwino. Izi zimapangitsa MOCA kukhala chida chamtengo wapatali kwa mafakitale omwe amadalira ma epoxy resin pazinthu zawo ndi ntchito zawo.
Kuphatikiza apo, pali mtundu wamadzimadzi wa MOCA wotchedwa Moka. Mtundu uwu ungagwiritsidwe ntchito ngati mankhwala ochiritsira polyurethane kutentha kwa chipinda, zomwe zimapangitsa kuti ukhale wosavuta kupanga. Kuphatikiza apo, Moka ikhoza kugwira ntchito ngati mankhwala ochiritsira polyurea popopera. Kusinthasintha kwake komanso kugwiritsa ntchito mosavuta kumapangitsa kuti ikhale chisankho chodziwika bwino pakati pa opanga.
Kulongedza ndi kusungira：
Kupaka:50kg/DRUM
Malo Osungirako：ayenera kukhala ozizira, ouma komanso opatsa mpweya wabwino.
Kukhazikika:Kutentha ndi kufiyira, chinyezi pang'ono. Palibe mayeso atsatanetsatane a matenda ku China, ndipo sizikutsimikizika kuti mankhwalawa ndi oopsa komanso ovulaza. Chipangizochi chiyenera kulimbitsa kuti chichepetse kukhudzana ndi khungu ndi kupuma mpweya kuchokera m'njira yopumira, ndikuchepetsa kuvulaza thupi la munthu momwe zingathere.
Chidule：
Mwachidule, MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) ndi chinthu chogwiritsidwa ntchito kwambiri komanso chamtengo wapatali chogwirizanitsa zinthu. Kugwiritsa ntchito kwake kwakukulu mumakampani opanga mphira, zokutira, ndi zomatira za polyurethane kumapangitsa kuti ikhale chisankho chabwino kwa opanga. Chifukwa cha kuthekera kwake kowonjezera mphamvu, kulimba, komanso kulumikizana kwa mankhwala, MOCA mosakayikira imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti zinthu zosiyanasiyana zikuyenda bwino komanso zikuyenda bwino.
