Musiyano pakati pe polyurethane MDI uye TDI masisitimu emashini elastomer
Nhanganyaya:
Polyurethane elastomer michina inoita basa rakakosha muindasitiri yemazuva ano.Zvisinei, kana zvasvika pakusarudza polyurethane system, pane nzira mbiri huru: MDI (diphenylmethane diisocyanate) system uye TDI (terephthalate) system.Ichi chinyorwa chichaongorora mutsauko uripo pakati peaya masisitimu maviri kubatsira muverengi kuita sarudzo ine ruzivo rweimwe application.
I. Elastomer Machines yePolyurethane MDI Systems
Tsanangudzo uye Maumbirwo: iyo MDI sisitimu ndeye polyurethane elastomer yakagadzirwa kubva ku diphenylmethane diisocyanate seyakanyanya mbishi zvinhu, kazhinji ine zvekubatsira senge polyether polyol uye polyester polyol.
Features uye Benefits:
Simba repamusoro uye abrasion kuramba: MDI system elastomers ine yakanakisa zvimiro zvemuviri uye inochengetedza kugadzikana munzvimbo dzakanyanya kushushikana.
Yakanakisa kuchembera kuramba: elastomers ane MDI masisitimu ane kuramba kwakanaka kune oxidation uye UV mwaranzi uye hupenyu hurefu hwesevhisi.
Kuramba kwakanaka kumafuta uye zvinonyungudutsa: MDI elastomers inoramba yakatsiga kana yaiswa kumakemikari akadai semafuta uye zvinonyungudutsa.
Nzvimbo dzekushandisa: Elastomers yeMDI system inoshandiswa zvakanyanya mukugadzira mota, zvishandiso zvemitambo uye zvigadzirwa zvemaindasitiri.
II.Polyurethane TDI system elastomer michina
Tsanangudzo uye maumbirwo: TDI system ndeye polyurethane elastomer yakagadzirwa ne terephthalate sechinhu chikuru mbishi, kazhinji iine zvinhu zvekubatsira senge polyether polyol uye polyester polyol.
Features uye Zvakanakira:
Yakanaka elasticity uye kupfava: TDI system elastomers ine yakakwira elasticity uye kupfava uye inokodzera zvigadzirwa zvinoda yakakwirira ruoko kunzwa.
Yakanakisa yakaderera-tembiricha yekukotama kuita: TDI system elastomers ichine yakanakisa kubhenda kuita munzvimbo dzakaderera-tembiricha, uye hazvisi nyore kukanganisa kana kutyora.
Inokodzera maumbirwo akaomarara: TDI elastomers inokunda mukugadzirwa kweakaomesesa maumbirwo kuti asangane neakasiyana dhizaini zvinodiwa.
Zvishandiso: TDI elastomers anoshandiswa zvakanyanya mufenicha uye metiresi, kugadzira shangu uye kurongedza zvinhu.
III.Kuenzanisa kweMDI uye TDI masisitimu
Mumunda we polyurethane elastomer michina, MDI neTDI masisitimu ane hunhu hwakasiyana uye zvakanakira.Matafura anotevera anozowedzera kuenzanisa misiyano yavo maererano nechimiro chemakemikari, zvimiro zvemuviri, kuchengetedza kwezvakatipoteredza uye chengetedzo, mutengo wekugadzira uye nzvimbo dzekushandisa:
| kuenzanisa chinhu | Polyurethane MDI system | Polyurethane TDI system |
| chimiro chemakemikari | Kushandisa diphenylmethane diisocyanate seyakanyanya mbishi zvinhu | Kushandisa terephthalate sechinhu chikuru mbishi |
| Maitiro ekupindura | High degree of crosslinking | shoma-yakabatana |
| zvinhu zvemuviri | - High simba uye kupfeka kuramba | - yakanaka elasticity uye kupfava |
| - Yakanakisa kuchembera kuramba | - Yakanakisa kukotama kuita pane yakaderera tembiricha | |
| - Mafuta akanaka uye kusagadzikana kwekunyungudika | - Inokodzera zvigadzirwa zvine maumbirwo akaomarara | |
| Kuchengetedzwa kwezvakatipoteredza uye kuchengeteka | yakaderera isocyanate yemukati | yakakwira isocyanate yemukati |
| Mutengo wekugadzira | mutengo wakakwirira | mutengo wakaderera |
| Nzvimbo yekushandisa | - Mugadziri wemotokari | - fenicha nemamatiresi |
| - Mitambo Equipment | - Kugadzira shangu | |
| - Industrial zvigadzirwa | - Packaging Materials |
Sezvinoonekwa kubva patafura iri pamusoro, elastomers e polyurethane MDI system ane simba rakawanda, kuramba kuchembera uye kuramba mafuta, uye akakodzera kushandiswa mukugadzira mota, midziyo yemitambo uye zvigadzirwa zvemaindasitiri.Kune rimwe divi, polyurethane TDI system elastomers ine yakanaka elasticity, kuchinjika uye yakaderera-tembiricha yekukotama zvivakwa, uye yakakodzera kushandiswa munzvimbo dzakadai sefenicha nemamatiresi, kugadzira shangu uye kurongedza zvinhu.
Izvo zvakakoshawo kuziva kuti iyo MDI system inodhura kugadzira, asi inopa zvirinani kuchengetedza kwezvakatipoteredza uye chengetedzo.Kusiyana neizvi, iyo TDI system ine yakaderera mutengo wekugadzira asi yakakwira isocyanate yemukati uye ine zvishoma zvishoma kune nharaunda hushamwari pane iyo MDI system.Naizvozvo, pakusarudza polyurethane sisitimu, vagadziri vanofanirwa kufunga nezvekuita kwechigadzirwa, zvinodiwa kwezvakatipoteredza uye zvipingamupinyi zvebhajeti kuitira kuti vagadzire chirongwa chakanyatsokodzera chekugadzira chinosangana nezvinodiwa zvekushandisa kwakasiyana.
IV.Sarudzo dzeKushandisa uye Kurudziro
Kusarudza iyo chaiyo sisitimu yemashandisirwo akasiyana: Tichifunga nezvechigadzirwa chinodiwa uye hunhu hwenzvimbo yekushandisa, kusarudza elastomers ane MDI kana TDI masisitimu inovimbisa kuita kwakanyanya uye mutengo-unoshanda.
Kuita Sarudzo zvine chekuita nekuita kwechigadzirwa uye bhajeti: kana uchisarudza sisitimu, kuita kwechigadzirwa, zvinodikanwa zvezvakatipoteredza uye zvipingamupinyi zvebhajeti zvinotariswa kugadzira mhinduro yakakodzera yekugadzira.
Mhedziso:
Polyurethane MDI uye TDI system elastomers imwe neimwe ine zvayakanakira uye yakakodzera kune zvigadzirwa zvinodiwa munzvimbo dzakasiyana.Kunzwisisa misiyano yacho kuchabatsira vagadziri kuita sarudzo dzine ruzivo kuti vaone kuti zvigadzirwa zvavo zvinoshanda nemazvo mumashandisirwo chaiwo.
