MXC-8 (DMCHA):Chinhu Chinoshandura Zvinhu Zvakasiyana-siyana Pakushandisa Foam Yakasimba
MXC-8, inozivikanwawo seDMCHA(Dimethylcyclohexylamine), chinhu chinoshanda zvikuru chinobva kuamine chinowanzoshandiswa mukugadzira furo repolyurethane rakagadzika, kusanganisiramapaneru esandwichuyemafuremu efenicha.
Mabhenefiti Akakosha eMXC-8 (DMCHA) mukugadzira Foam:
Nguva Yekukurumidza Kupora: DMCHA inokurumidzisa maitiro ekugadzirisa masisitimu epolyurethane, ichibatsira vagadziri kuwana nguva yekukurumidza yekugadzira furo rakaoma, sengekugadzira furemu yefenicha.
Maumbirwo eFuro Akavandudzwa: MXC-8 inowedzera kuumbwa kwemasero akanaka, akafanana mufuro, izvo zvinovandudzasimba rekumanikidza uyekugadzikana kwehukuru chekupedzisira chigadzirwa. Izvi zvakakosha pakushandisa zvakaita semafuremu efenicha akaomarara, uko kusimba kwechimiro kuri chinhu chakakosha pakuona kuti inogara kwenguva refu uye kuti inoshanda kwenguva refu.
Kuchinja-chinja muZvishandiso: Pamusoro pema sandwich panels, MXC-8 inoshandiswawo mune zvimwe zvikamu zvefuro rekushongedza, zvichibatsira kugadzira zvinhu zvakareruka asi zvakasimba zvekugadzira fenicha nezvinhu zvekuvaka. Inonyungudika muma polyols mazhinji uye organic solvents, asi hainyungudike mumvura. Inogona kushandiswa sechinhu chinobatsira pakushandisa zvakasiyana-siyana kusanganisira marudzi ese emafuro akasimba ekurongedza.

MXC-41:Kugona Kwepamusoro Kwekuburitsa Furo reMasisitimu Anobatana Nemvura
Chimwe chinhu chakakosha pakugadzira mafoam akaomarara epolyurethane, kunyanya mumapaneru esandwich, iriMXC-41. Inozivikanwa nekukwanisa kwayo kuburitsa furo zvakanyanya, MXC-41 inoshanda zvakanyanya mumasisitimu akaomarara emvura, uko mvura inoshandiswa kugadziraCO2gasi, zvichikurudzira kukura kwefuro panguva yekugadzika.
Mabhenefiti Akakosha eMXC-41 mukugadzira Foam:
Kugona Kuburitsa Furo Kwakanaka Kwazvo: MXC-41 inoshanda zvakanaka mumasisitimu anoshandisa mvura semushonga wefuro, zvichiita kuti furo rikure zvakanaka uye zvakaenzana. Kukwanisa uku kwefuro kwakakosha pakugadzira mapaneru esandwich, sezvo chimiro chemasero chakafanana chakakosha pakudzivirira kupisa uye kusimba kwemuchina.
Hunhu Hwakasimbiswa hweMagadzirirwo: Hunhu hwechinoburitsa furo hunobatsira kugadzira furo rakasimba risingaremi chete asiwo rine simba guru rekutakura zvinhu uye simba rekudzvanya, zvichiita kuti rive sarudzo yakakura yekushandisa muchimiro chakadai semasandwich panels nemafuremu efenicha.
Mashandisirwo muSandwich Panels uye Furemu dzefenicha
Mapaneru eSandwich: ZveseMXC-8 (DMCHA)uyeMXC-41zvakakosha pakugadzirwa kwemapaneru esandwich, ine furo rakasimba rakasungirirwa pakati pezvikamu zviviri zvezvinhu (zvinowanzo simbi kana plastiki). Mapaneru aya anoshandiswa zvakanyanya mukuvaka, kuputira, uye kutakura nekuda kwehunhu hwekudzivirira kupisauyesimba remakanika. MXC-8 inobatsira mukuita kutikupora nekukurumidzauyekuumbwa kwefuro kwakasimba, ukuwo MXC-41 ichivimbisa kuti furokushanda zvakanaka kwefurouye kusimba kwechimiro chose.
Mafuremu efenicha akaomarara eFoam: Iyofuro rakaomararainoshandiswa mumafuremu efenichavanobatsirwa nekushanda nekukurumidza uye hunhu hwakasimba hwemakanika hunopiwa neMXC-8. Hunhu uhwu hunobvumira kugadzirwa kwezvinhu zvefenicha zvakareruka, zvinogara kwenguva refu zvinoshanda uye zvinoyevedza.
