99% MOCA 4,4′-Methylenebis(2-chloroaniline) CAS 101-14-4
4,4' - Methylenebis (2-chloroaniline), yomwe imatchedwanso MOCA, ndi chinthu chomwe chimagwiritsidwa ntchito ngati cholumikizira cholumikizira / chowonjezera unyolo pazinthu za polyurethane, makamaka pa ma polyurethane elastomers (CPU). Ma polyurethane elastomers ndi osinthasintha ndipo ali ndi mawonekedwe otanuka ngati rabara koma ali ndi mawonekedwe ofunikira, amaphatikiza kutakasuka kwakukulu kwa rabara ndi kulimba kwa pulasitiki. MOCA imakhala ndi kukhazikika kwa utoto kutentha kwambiri. Ma elastomers a MOCA ndi abwino pakukanda / kukhudza / mankhwala / mafuta / ozone komanso kukana kuzizira, kutakasuka mosasamala kanthu za kuuma kwakukulu kapena kochepa (Shore A to Shore D rating), mphamvu yayikulu yogwira / kung'ambika / kupsinjika, komanso kuyamwa kwa kugwedezeka. Ndi moyo wautali wa mphika, ndikosavuta kugwiritsa ntchito, mutha kugwira ngakhale ndi manja m'malo mwa makina. Chifukwa cha mawonekedwe ndi zabwino zake, MOCA ndiye cholumikizira cholumikizira / chowonjezera cha urethane elastomers (TDI system). Pakadali pano, ndi chothandizira padziko lonse lapansi pazinthu za Epoxy.
Poyerekeza ndi DETDA ndi DMTDA, pali ubwino woonekeratu wa MOCA motere.
1. Chopangidwa chomalizidwacho chili ndi mtundu wopepuka.
2. MOCA ndi yolimba, motero, ndi yosavuta kusunga komanso kuipitsa pang'ono.
3. Yosavuta kugwiritsa ntchito. Imakhala nthawi yayitali m'mbale.
4. Modulus ndi yapamwamba.
5. Mtengo wotsika.
MOCA ndi chowonjezera cha diamine chain extender kapena chochiritsira chomwe chimagwiritsidwa ntchito kwambiri popanga ma elastomer a polyurethane, zipangizo za elastomeric pavement, zokutira zosalowa madzi za PU, zomatira za PU, thovu la PU, ndi zina zotero.
Ma elastomer a MOCA-chain-extended PU amagwiritsidwa ntchito kwambiri m'magawo monga makina, nyumba, magalimoto, mayendedwe, mafakitale amigodi, zida zamagetsi zolumikizirana ndi malo ochitira masewera, ndi zina zotero.
MOCA ingagwiritsidwenso ntchito pokonza utomoni wa epoxy.
MOCA yathu ndi yoyera kwambiri, MOCA yosungunuka ndi madzi owonekera opanda utoto mpaka achikasu, imalimbikitsidwa kugwiritsidwa ntchito pazinthu monga gudumu la skateboard, chopukutira mpunga cha polyurethane, chopukutira, ndi chopepuka.
Zophimba za PU zamitundu yosiyanasiyana, ndi zina zotero zomwe zimafuna mawonekedwe abwino komanso mawonekedwe owonekera osawoneka bwino.
MOCA ndi chowonjezera cha aromatic diamine chain extender kapena chothandizira kuchiritsa cha polyurethane elastomers (PU). Ma elastomers a MOCA-base ali ndi makhalidwe abwino kwambiri, amagwiritsidwa ntchito kwambiri m'malo osiyanasiyana kuphatikizapo zomangamanga, zomangamanga, magalimoto, migodi, semi-conductor, epoxy, malo ochitira masewera ndi zina zotero.
1. Wothandizira kulumikiza makampani amagetsi.
2. Zipangizo zosalowa madzi / zokutira zogwiritsidwa ntchito pamakampani omanga ndi zomangamanga.
3. Chowonjezera unyolo cha ma elastomer a PU, mwachitsanzo cholumikizira cha rabara la jaw, kangaude wa PU.
4. Chothandizira kuchiritsa utomoni wa epoxy.
5. Zigawo zogwiritsidwa ntchito m'mafakitale, mwachitsanzo malamba otumizira katundu, ma caster, ma guide roller, ndi ma coupling.
6. Mapepala oyeretsera ma shock absorption a makampani opanga magalimoto.
7. Ma roller osindikizira, masamba a ng'oma, masamba otsekereza, masamba oyeretsera, masamba okhwinyata a makampani osindikizira.
8. Zinthu zotsekera.
9. Zipangizo zotetezera kutentha kwa epoxy.
10. Chipepala cha urethane choletsa mabakiteriya.
11. Chophimba cholekanitsa mchere.
12. Mapaipi olumikizirana.
Kulongedza: 25 kg kapena 50kg/ng'oma kapena thumba la ulusi
Kunyowa pang'ono kwa chinyezi; pewani kukhudzana ndi madzi. Sungani kutali ndi dzuwa.
