Macatalyst ePolyurethane anoita basa rinokosha mukugadzirwa kwepolyurethanes, achibatsira mukuita kuti zvinhu izvi zvishande zvakasiyana-siyana. Pakati pemacatalyst akasiyana-siyana aripo, MXC-T120 inoonekwa sesarudzo ine simba uye inoshanda yekushandiswa kwepolyurethane, kubva pakupfapfaidza furo kusvika kupolyurethane yakaoma uye zvigadzirwa zvekuumba zvinochinjika zvakanyanya. Kunzwisisa mashandiro emacatalyst epolyurethane uye zvakanakiraMXC-T120Zvakakosha pakuvandudza maitiro ekugadzira uye kuita kuti zvinhu zvishande zvakanaka.
Chinhu chinobatsira kuwedzera simba remakemikari pasina kushandiswa. Panyaya yekugadzira polyurethane, zvinhu zvinobatsira zvikuru pakukurumidzisa simba rekuita pakati pemapolyol nemaisocyanates, izvo zviri zvikamu zvikuru zvepolyurethane. Kuita uku, kunozivikanwa segelation, kunoumba polymer matrix yepolyurethane. MXC-T120, chinhu chinobatsira zvikuru mukuita kuti simba rekuita uku riwedzere, zvichipa simba rekuita kuti zvinhu zvishande zvakanaka uye kugadzikana kwehydrolytic kuwedzere.
Rimwe remabasa makuru e polyurethane catalysts seMXC-T120 nderekudzora nguva ye gelling. Nekukurumidzira maitiro e gelation, catalysts dzinobatsira mukugadzira network ye polymer yakasimba nekukurumidza uye zvinobudirira. Izvi zvakakosha zvakanyanya mukushandiswa kwakadai sekupfapfaidza furo, uko kukurumidza kupora kwakakosha kuchengetedza chimiro uye kusimba kwechimiro. Pamusoro pezvo, MXC-T120'Basa rakasimba rekugadzira zvinhu zvinovaka muviri rinovimbisa kushanda kwakasimba uye kwakavimbika mumaforoma akasiyana epolyurethane.
Kupfuura kudzora nguva yegelling, ma catalysts anoitawo basa rakakosha mukuenzanisa mativi ekuita, kusanganisira mafambiro emvura nema isocyanates kugadzira gasi re carbon dioxide (CO2). Maitiro aya akakosha mukuita kwefuro, izvo zvinopa hunhu hwakanaka senge insulation uye cushioning kuma polyurethane foams. Zvisinei, kugadzirwa kwegasi rakawandisa kunogona kukonzera zvikanganiso uye kukanganisa kunaka kwezvinhu. MXC-T120 inobudirira mukugadzirisa mativi aya, ichivimbisa kuenzana kwakakwana pakati pekugadzirwa kwe polymer nekugadzirwa kwegasi, zvichikonzera furo remhando yepamusoro rine chimiro chemasero chakafanana.
Zvichienzaniswa neamine catalysts, dzinobva kuammonia (NH3) uye dzinosiyana mukushanda zvichienderana nechimiro chadzo uye hunhu hwadzo, MXC-T120 inopa kushanda kwepamusoro maererano nekugadzikana kwehydrolytic. Amine catalysts, kunyanya tertiary amines, dzinowanzo shandiswa mukugadzira furo nekuda kwekukwanisa kwadzo kukurudzira kuumbwa kweCO2. Zvisinei, dzinogonawo kukonzera kusagadzikana uye kunzwa kwehunyoro, zvingangokanganisa kugadzikana kwenguva refu kwezvinhu. MXC-T120, ine dibutyltin composition yayo, inopa kuramba kwakanyanya kuhydrolysis, ichivimbisa zvigadzirwa zve polyurethane zvakasimba uye zvakagadzikana kunyangwe mumamiriro ezvinhu akaoma.
Mukupedzisa,polyurethane catalystMXC-T120 chinhu chine simba uye chinoshanda zvakasiyana-siyana chinovandudza zvakanyanya kushanda zvakanaka uye mhando yekugadzirwa kwepolyurethane. Basa rayo guru rekugadzirisa, kugadzikana kwayo kwakanyanya kwehydrolytic, uye kugona kwayo kuyera mativi emhedzisiro zvinoita kuti ive sarudzo yakakodzera kune akasiyana mashandisirwo, kubva pakupfapfaidza furo kusvika kuzvigadzirwa zvekuumba zvakaoma uye zvinochinjika. Nekushandisa mabhenefiti eMXC-T120, vagadziri vanogona kuwana zvinhu zvepolyurethane zvepamusoro nekushanda kwakawedzerwa uye kugara kwenguva refu.
