Zvinhu zvinokonzeresa polyurethaneine basa rakakosha mukuvandudza mashandiro uye kushanda zvakanaka kwezvigadzirwa zvepolyurethane. Pakati pezvinhu zvakawanda zvinowanikwa, MXC-t125 inoonekwa sechinosimudzira simbi chisina mutobvu chinozivikanwa nehunhu hwayo hwakanaka uye mashandisirwo ayo akasiyana-siyana. Chinyorwa chino chinotarisa zvinhu zvakasiyana zveMXC-t125 uye mashandisirwo ayo mumapolyurethane akaomarara.
Hunhu Hukuru hweMXC-t125
MXC-t125 isimbi isina mutobvu yakagadzirwa kuti ishande zvakanaka neamine cocatalysts. Kubatana uku kunowedzera basa re catalytic, zvichikonzera kushanda kwepamusoro mu polyurethane formulations. Kana tichienzanisa ne dibutyltin compounds yechinyakare, MXC-t125 inoratidza basa re catalytic rakawanda uye kusarudza kune polyurethane (polyol-isocyanate) reaction. Pamusoro pezvo, inopa kugadzikana kuri nani kwe hydrolysis, zvichiita kuti ive sarudzo yakavimbika kune akasiyana mashandisirwo e polyurethane.
Kushandiswa muRigid Polyurethanes
Ma polyurethane akaomarara anoshandiswa zvakanyanya muindasitiri yekudzivirira kupisa, kuvaka, uye mota nekuda kwehunhu hwavo hwakanaka hwekudzivirira kupisa, kunaka kwechimiro, uye kugara kwenguva refu. MXC-t125 inoita basa guru mukugadzirwa kwe polyurethane dzakaoma dzemhando yepamusoro nekuona kuti polymerization inoshanda uye inodzorwa.
1. Kuwedzerwa Kwebasa reCatalytic: Basa guru reMXC-t125 rinoita kuti polyurethane iite nekukurumidza uye nemazvo. Izvi zvinobatsira zvikuru mukugadzirwa kwemafuro akaomarara, uko nguva yekukurumidza kupora inokosha kuchengetedza kusimba kwechimiro uye hunhu hwekudzivirira hwechigadzirwa chekupedzisira.
2. Kugadzikana kweHydrolysis Kwakavandudzwa: Mapolyurethane akaomarara anowanzo sangana nemamiriro akasiyana-siyana ekunze, kusanganisira hunyoro. Kugadzikana kwehydrolysis kwakanyanya kweMXC-t125 kunoita kuti catalyst irambe ichishanda kunyangwe paine mvura, nokudaro zvichiwedzera kugara kwenguva refu uye kugara kwenguva refu kwezvigadzirwa zvepolyurethane zvakaoma.
3. Kugadziriswa Kwakafara: MXC-t125 inopa huwandu hwakakura hwekugadzirisa mumafomula ekutsungirira kwakanyanya. Kuchinjika uku kunobvumira vagadziri kugadzirisa maitiro ekugadzira kuti vawane hunhu hwefuro hwavanoda, hwakadai sekuwanda, simba rekumanikidza, uye kuputira thermal.
4. Kugadzikana Kwakanaka Kwekuchengetedza: Kugadzikana kwekuchengetedza chinhu chakakosha kune chero chinhu chinoshandiswa mumaindasitiri. MXC-t125 inoratidza kugadzikana kwakanaka kwekuchengetedza, ichivimbisa kuti hunhu hwayo hwekugadzirisa zvinhu hunoramba hwakafanana nekufamba kwenguva. Kugadzikana uku kunoshandura mashandiro anofungidzirwa uye akavimbika mukugadzirwa kwezvinhu.
Kushandiswa Kwakasiyana-siyana muCASE Applications
Pamusoro pekushandiswa kwayo muma polyurethane akaomarara, MXC-t125 yakakodzerawo maCoatings, Adhesives, Sealants, uye Elastomers (CASE). Kugona kwayo kushanda segel catalyst mumafomu aya kunoratidza kushanduka kwayo uye kushanda kwayo mumasisitimu akasiyana e polyurethane. Kushanduka uku kunoita kuti MXC-t125 ive chinhu chinokosha kune chero chishandiso chemugadziri we polyurethane.
Mhedziso
MXC-t125 haina leadchinowedzera simba resimbiiyo inopa basa guru rekugadzirisa zvinhu, kugadzikana kwepamusoro kwehydrolysis, uye kugadzikana kwakanyanya kwekuchengetedza. Kuenderana kwayo neamine cocatalysts uye huwandu hwakakura hwekugadzirisa kunoita kuti ive sarudzo yakakodzera yekushandiswa kwepolyurethane yakaoma. Ingave ichishandiswa mukudzivirira kupisa, kuvaka, kana maindasitiri emotokari, MXC-t125 inoita kuti pave nekugadzirwa kwezvigadzirwa zvepolyurethane yakasimba zvemhando yepamusoro, zvinogara kwenguva refu, uye zvinoshanda.
