Zvinopihwa nePMDETA (MXC-5)reactivity ye catalytic yakaenzanapakati pekuita kwefuro ne gelling, zvichiita kuti pave nekudzora kwakanaka kwekugadzirisa. Kushanda kwayo kwepamusoro kunobvumiranguva dzinokurumidza kuporauyechimiro chesero chakafanana, zvichibatsira pakuvandudza mashandiro emuchina uye kupisa kwezvigadzirwa zvepolyurethane.
Mashandisirwo ePMDETA muindasitiri yePolyurethane
1. Mafuro ePolyurethane Akasimba
PMDETA (MXC-5) inoshandiswa zvakanyanya mukugadzirafuro rakasimba repolyurethane, uko kunowedzerakushanda zvakanakauyekufanana kweseroMafuro aya anowanzo shandiswa mu:
- Furo repurasitiki rinopfapfaidzwa (SPF)kuputira
- Masisitimu ekudzivirira firiji nefiriji
- Kugadzirwa kwebhodhi uye kugadzirwa kwepaneru kunoenderera mberi
- Kudzivirira mapaipi nemidziyo yemagetsi
Simba rayo guru rekugadzirisa zvinhu rinotsigira zvese zviri zviviriyakafuridzirwa nemvurauyeHFO-yakaputikamasisitimu, zvichiita kuti ive yakakodzera mishonga yemazuva ano, ine utsi hushoma.
2. Mafuro Anochinjika Zvishoma uye Madiki
In zvikumbiro zvemotokari uye zvekurongedza, PMDETA inoshanda sechinhu chinobatsira zvikuru pakubvisa furo chinokurudziramapurofayiri ekukwira akatsetsekauyemaumbirwo emasero akanaka, akafananaInobatsira vagadziri kuwana zvinhu zvepolyurethane zvakareruka asi zvakasimba zvinoshandiswa mumaganda edashboard, zvigadziko zvemusoro, uye zvinhu zvinobata kukanganiswa.
3. Thermoplastics, Elastomers, uye Coatings
Kupfuura furo repolyurethane, PMDETA inoshanda seligand inoshanda zvakasiyana-siyana kana kuti co-catalyst in polymerization uye maitiro ekuporesaInoita basa rakakosha mukusimudzirathermoplastics, elastomers, uye machira anoshanda zvakanyanya, zvichiita kuti mapolymers ave nekuchinjika kwakagadzirirwa, kunamira, uye kuramba makemikari.
Kukosha kwePMDETA (MXC-5) muMaindasitiri
Kuchinja-chinja kwePMDETA kuri mukushandiswa kwayomabasa maviri se ligand uye catalystInogona kushanda pamwe chete nemaion esimbi kuti iite kuti polymerization, crosslinking, uye kuporesa reactions zvive nyore — matanho akakosha mukugadziramasisitimu epamusoro epolyurethaneuyemapolima akakosha.
Mumakemikari epolyurethane, kushanda zvakanaka kwePMDETA kunobvumira vagadziri kuti:
- Deredza mushonga we catalyst pasina kukanganisa reactivity
- Kupfupisa nguva dzekugadzira uye nguva dzekupisa
- Kuvandudza chimiro chefuro uye kunaka kwenzvimbo yacho
- Deredza kuburitsa kwemhepo uye kudzora hwema zviri nani
Kuenderana kwayo nemaitiro akasiyana-siyana epolyol uye isocyanate kunotsigirawoisingakuvadzi nharaunda uye isingashandise simba zvakanyanyakugadzirwa kwefuro, zvichienderana nekudiwa kuri kukura kwezvinhu zvinodzivirira kutonhora zvinogara kwenguva refu.
Mabhenefiti ekushandisa PMDETA (MXC-5)
- Basa guru rekugadzirisa zvinhukune zvese maitiro e gelling uye blowing
- Kunyungudika kwakanaka kwazvomu polyol blends nezvimwe zvinonyungudutsa
- Kugadzikana kwefuro kwakawedzerwauye kufanana
- Rudzi rwakakura rwekushandisapakati pemafuro, ma elastomer, uye ma coatings
- Yakakodzera mafomura ane HFO, kuderedza kukanganisa kwezvakatipoteredza
Hunhu uhwu hunoita kuti MXC-5 ive chinhu chinokurudzirwa nevagadziri vane chinangwa chekugadzirisa mashandiro, deredza mutengo, uye simbisa kushanduka kwekugadzira.
