Masisitimu Ekugadzira Furo eHFO: Mhinduro Inobatsira Pakuchengetedza Mafuro ePolyurethane

Mahydrofluoroolefins (HFOs) anomiririra chizvarwa chitsva chezvishandiso zvekufema zvine hushamwari kune nharaunda zvinoshandiswa mu polyurethane foams. Nekuwedzera kwekutarisa pasi rose pakuderedza kukanganisa kwezvakatipoteredza, maHFO ari kuve sarudzo inofarirwa kushandiswa kwakasiyana-siyana, achitsiva mahydrofluorocarbons ekare (HFCs) nekuda kwechimiro chawo chakanaka chezvakatipoteredza.

Chii chinonzi HFO?

MaHFO iboka remakemikari anoshandiswa zvakanyanya semafiriji, ma blowing agents, ma propellants, uye solvents. Muma polyurethane foaming systems, maHFO anoshanda sema blowing agents anobatsira kugadzira chimiro chemasero emafuro, zvichibatsira mukudzivirira kwawo, kuomarara, uye kugadzikana.

MaHFO awana mukurumbira sezvo maHFC ari kubviswa zvishoma nezvishoma zvichienderana nemitemo yepasi rose yakanangana nekuderedza zvinhu zvine mukana wekupisa kwepasi rose (GWP). Kunyange hazvo maHFC, akadai seHFC-245fa, aishandiswa zvakanyanya mumaitiro efuro, ane GWP yakakwira uye anobatsira mukuderedza ozone. Kusiyana neizvi, maHFO haana mukana wekudzikisa ozone (ODP) uye anoderedza zvakanyanya GWP, zvichiita kuti ave imwe nzira inogara kwenguva refu.

Mabhenefiti eHFO Foaming Systems

1. Kukanganisika Kushoma Kwezvakatipoteredza: Chinhu chikuru chinobatsira zvikuru chemaHFO ndechekuti haanyanyi kukanganisa nharaunda. MaHFO haana ODP uye GWP shoma, izvo zvinobatsira kuderedza kuburitswa kwemagasi anodziya pasi pevhu.
2. Kushanda Nesimba Zvakanaka: Mafuro akavakirwa paHFO anoratidza hunhu hwakanaka hwekudzivirira kupisa, zvichiwedzera kushanda zvakanaka kwesimba remashandisirwo akaita semafiriji, mafiriji, mafiriji anopfapfaidza, uye zvinhu zvekuvaka.
3. Kuchengetedzeka uye Kuchinja-chinja: HFOs hadzibati, hadzina chepfu, uye dzinopa hunyanzvi hwakasiyana-siyana mumhando dzakasiyana dzemafuro, kusanganisira mafuro akaomarara uye anochinjika. Dzakakodzera zvakanyanya kune masisitimu anoshandisa mvura semushonga wekufema pamwe chete, zvichideredza kuvimba nemishonga yechinyakare.
4. Zvivakwa zveFoam Zvakavandudzwa: HFOs dzinobatsira mukuvaka masero akanaka, akafanana mumafuro epolyurethane, izvo zvinobatsira kuchengetedza simba remuchina, kugadzikana kwehukuru, uye kushanda kwefuro rose. Dzinoderedzawo kuputsika kwefuro, dzinovandudza kupora kwepamusoro, uye dzinowedzera kunamira pakati pemafuro.

Remangwana reHFOs muPolyurethane Foams

Sezvo kudiwa kwezvinhu zvisingakuvadzi nharaunda uye zvinoshandisa simba shoma pasi rose kuri kuramba kuchikura, masisitimu eforoma akavakirwa paHFO anotarisirwa kuwedzera mukurumbira muindasitiri yeforoma yepolyurethane. Kuchinja kubva kuHFC kuenda kuHFO hakungoenderane nemitemo yezvakatipoteredza chete asiwo kunovimbisa kuti vagadziri vanogona kuramba vachigadzira foroma dzinoshanda zvakanaka pasina kukanganisa nharaunda.

Kukambani yedu, takazvipira kusimudzira tekinoroji ye polyurethane catalyst kutsigira masisitimu eHFO foaming.Chinhu chinobatsira pakugadzira MXC-70, yakagadzirirwa kushandiswa nemasisitimu ane HFO, inovandudza kusimba kwenzvimbo, inokurudzira kukwira zvakanaka, uye inowedzera kunamira kwesubstrate. Yakakodzerawo masisitimu anoshandisa mvura semushonga wekubvisa furo pamwe chete, ichipa kuchinjika uye kuburitsa hutsi hwakaderera mukushandiswa kwefuro rinochinjika uye rakaomarara.

Kana uchifarira masisitimu ekugadzira furo eHFO kana eduChinhu chinobatsira pakugadzira MXC-70, ndapota taura nesu kuti uwane rumwe ruzivo painfo@mingxuchem.com.
