Ma polyurethane elastomers zvinhu zvinoshandisika zvakasiyana-siyana zvinoratidza hunhu hwakanaka hwemakanika senge kuchinjika kwakanyanya, kuramba kupfeka uye kugara kwenguva refu. Hunhu uhwu hunoita kuti akwanise kushandiswa mumaindasitiri akasiyana-siyana, kusanganisira zvikamu zvemotokari, shangu, zvisimbiso uye machira. Kugadzirwa kwepolyurethane elastomers kunoda kudzora kwakaringana kwemakemikari anobatanidzwa, kunyanya kana paine chisungo cheurethane pakati pepolyol neisocyanate. Polyurethane catalysts inoita basa rakakosha pano.
Zvinhu zvinokonzeresa polyurethanezvinokwanisa kudzora kumhanya uye kushanda zvakanaka kwe polyurethane reaction. Zvinokanganisa kuenzana pakati pe gelation (polyol-isocyanate) uye furo (water-isocyanate), izvo zvinosarudza zvakananga hunhu hwekupedzisira hwe elastomer. Nekusarudza catalyst chaiyo, vagadziri vanogona kugadzirisa mamiriro ekugadzirisa uye kugadzirisa hunhu hwe elastomer kuti ienderane nezvinodiwa zvekushandisa.
Chimwe chinhu chikuru chinoshandiswa mukugadzira polyurethane elastomers iMXC-37, inozivikanwawo se dimethylethanolamine ether (DMAEE).MXC-37 imushonga weamine une hutsi hushoma, une hwema hushoma, unoshandiswa zvakanyanya mukushandiswa kusingadi maamine akawanda uye kushanda kwepamusoro. Hunhu hwakasiyana hweMXC-37 hunoita kuti ive yakakodzera zvakanyanya kune ester-based stabilizer soft foam, microcellular foam, elastomers, reaction injection molding (RIM) uye rigid foam packaging applications.
MXC-37muPolyurethane Elastomers
MXC-37ine mabhenefiti akati wandei mukugadzirwa kwe polyurethane elastomers. Inoshanda zvakanyanya mukusimudzira mashandiro efuro uye yakakodzera mafomura ane mvura yakawanda. Kushanda kwayo mufuro kunokurudzira kuumbwa kwemabubbles zvakanaka uye chimiro chemasero chakafanana, izvo zvakakosha pakushandiswa senge ma microcellular foams nema elastomers.
Mukushandiswa kwe elastomer, MXC-37 inoita kuti ikwanise kupora nekukurumidza uye zvakaenzana, izvo zvinovandudza hunhu hwe elastomer, zvakaita sekuwedzera simba rekudhonza uye kuchinjika. Izvi zvinoita kuti ive sarudzo yakakurumbira yekugadzira zvikamu zve elastomer zvinogara kwenguva refu zvinoda kuchinjika kwakanyanya, zvakaita se seals, gaskets uye zvikamu zvemota.
Pamusoro pezvo, hunhu hweMXC-37 hushoma uye hapana hunhu hwekuburitsa hunobva mumuviri zvinobatsirawo zvikuru, kunyanya mukushandiswa kusinganzwi hwema. Hwema hweamine hunowanzobatanidzwa ne polyurethane catalysts hunoderedzwa kana uchishandisa MXC-37, zvichiita kuti ive yakakodzera zvigadzirwa zvinosangana zvakananga nevatengi, zvakaita seshangu nezvinhu zvekushongedza.
Mashandisirwo Anoshanda Zvakasiyana-siyana
Kushanda nesimba kweMXC-37 hakungogumiri pa elastomers chete, asiwo kunosvika kune mamwe masisitimu e polyurethane foam. Mukushandiswa kwe microcellular foam, inobatsira kugadzira furo rine maburi madiki uye akafanana, izvo zvinowedzera kugona kwechinhu kunyudza uye kutsvedza. Mu reaction injection molding (RIM), MXC-37 inobatsira kuumba zvikamu zvakaoma nekukurumidza, kuwedzera kugona, uye kugadzira zvikamu zvakareruka, zvinoshanda zvakanyanya zvekushandisa mumotokari nemumaindasitiri.
Pamusoro pezvo, MXC-37 inogona kushandiswa mukushandisa foam packaging yakasimba, uko ichiita kuti furo riwedzere, zvichiita kuti insulation irambe ichidziya uye ichidzivirirwa zvakanaka. Chinhu ichi chinoita kuti catalyst isanhuwe zvakanyanya uye hachibudisi mweya zvakanaka chinobatsirawo mukushandisa uku, zvichideredza kukanganiswa kwezvakatipoteredza uye kugadzirisa mamiriro ebasa.
Mhedziso
Mukupedzisa, zvinhu zvinokonzeresa polyurethane zvakaita seMXC-37 (DMAEE)zvinhu zvakakosha mukugadzirwa kwe polyurethane elastomers nedzimwe nzira dzefuro. Kugona kwavo kudzora mwero wekuita, kuvandudza mhando yefuro, uye kuderedza kunhuhwirira kunoita kuti zvive zvakakosha mumaindasitiri akasiyana-siyana. MXC-37, ine simba rayo guru rekuburitsa furo uye hunhu hushoma hwekuburitsa furo, inopa vagadziri mhinduro yakavimbika yekugadzira zvigadzirwa zve polyurethane zvinoshanda zvakanyanya, kubva kuma elastomers kusvika kuma microcellular foam uye kurongedza furo kwakasimba.
