Intshayelelo

I-PMDETA, mfutshaneI-Pentamethyldiethylenetriamine, yiulwelo olucacileyo olungenambala ukuya kolutyheliyaziwa ngomsebenzi wayo onamandla wokutsala kunye nokuhambelana okubanzi ekuvelisweni kweekhemikhali.Inombolo ye-CAS 3030-47-5, i-PMDETA yiinyibilika lula emanzini nakwizinto eziphilayo, nto leyo eyenza ukuba ibe lukhetho olufanelekileyo kwiintlobo ngeentlobo zeukwenziwa kwepolymerization kunye nokusetyenziswa kwe-polyurethane.

Iimpawu eziphambili zeI-PMDETA (MXC-5)

Izibonelelo zePMDETA (MXC-5)reactivity elinganiselayo ye-catalyticphakathi kweempendulo ze-foam kunye ne-gelling, ukuqinisekisa ulawulo oluhle kakhulu lokucubungula. Umsebenzi wayo ophezulu uvumelaamaxesha okunyanga akhawulezayokwayeisakhiwo seseli esifanayo, inegalelo kwiipropati ezingcono zoomatshini nezobushushu zeemveliso ze-polyurethane.

Ukusetyenziswa kwe-PMDETA kwiShishini lePolyurethane

1. Amagwebu ePolyurethane aqinileyo

I-PMDETA (MXC-5) isetyenziswa kakhulu kwimveliso yeamagwebu e-polyurethane aqinileyo, apho kuphucula khonaukusebenza kakuhlekwayeukufana kweeseliEzi foams zisetyenziswa kakhulu kwezi:

• I-spray polyurethane foam (SPF)ubushushu bomzimba
• Iinkqubo zokukhusela iifriji kunye neefriji
• Isitokhwe sebhodi kunye nemveliso yephaneli eqhubekayo
• Ukukhusela imibhobho kunye nezixhobo

Amandla ayo aphezulu okubangela ucatalytic axhasa zombiniivuthelwe ngamanzikwayeI-HFO-eqhumisekileyoiinkqubo, nto leyo eyenza ukuba ifaneleke kwiifomyula zanamhlanje, ezinokukhupha umbane omncinci.

2. Amagwebu aguquguqukayo kancinci kunye namancinci

In izicelo zeemoto kunye nokupakisha, i-PMDETA isebenza njengesikhuthazi esisebenzayo sokukhupha amagwebu esikhuthazaiiprofayili zokunyuka okugudileyokwayeizakhiwo zeeseli ezintle nezihambelanayoInceda abavelisi ukuba bafumane izinto ze-polyurethane ezilula kodwa ezihlala ixesha elide ezisetyenziswa kwiizikhumba zedeshibhodi, iindawo zokubeka intloko, kunye nezinto ezithintela impembelelo.

3. Iithermoplastics, iiElastomers, kunye neeCoatings

Ngaphaya kweefoam ze-polyurethane, i-PMDETA isebenza njengei-ligand esebenza ngeendlela ezininzi okanye i-co-catalyst in ukwenziwa kwepolymerization kunye neempendulo zokuphilisaIdlala indima ebalulekileyo ekuphuhliseniiithermoplastics, ii-elastomers, kunye neengubo ezisebenza kakuhle, okuvumela iipolymers ezineukuguquguquka okulungiselelweyo, ukunamathela, kunye nokumelana neekhemikhali.

Ukubaluleka kwezeShishini kwe-PMDETA (MXC-5)

Ukuguquguquka kwe-PMDETA kuxhomekeke kwindlela yayo yokusebenza.indima ephindwe kabini njenge-ligand kunye ne-catalystIngasebenzisana nee-ion zesinyithi ukuze kube lula ukwenza i-polymerization, ukudibanisa, kunye nokulungisa ii-reactions - amanyathelo abalulekileyo ekuveliseniiinkqubo ze-polyurethane eziphambilikwayeiipolima ezikhethekileyo.

Kwikhemistri ye-polyurethane, ukusebenza kakuhle kwe-PMDETA kwe-catalytic kuvumela abavelisi ukuba:

• Nciphisa idosi ye-catalyst ngaphandle kokubeka emngciphekweni ukusabela kwi-reactivity
• Nciphisa imijikelo yemveliso kunye namaxesha okunyibilika
• Phucula ulwakhiwo lwefoam kunye nomgangatho womphezulu
• Fumana ukukhutshwa komoya okuncinci kunye nolawulo olungcono lwevumba

Ukuhambelana kwayo neenkqubo ezahlukeneyo ze-polyol kunye ne-isocyanate kuyaxhasainobuhlobo nokusingqongileyo kwaye igcina umbane ngendlela efanelekileyoukuveliswa kwefoam, okuhambelana nemfuno ekhulayo yeizixhobo zokukhusela ezizinzileyo.

Iingenelo zokusebenzisa i-PMDETA (MXC-5)

• Umsebenzi ophezulu wokutsala amandlazombini ii-gelling kunye nee-blowing reactions
• Ukunyibilika okugqwesileyokwiingxube ze-polyol kunye nezinye izinyibilikisi
• Uzinzo oluphuculweyo lwefoamkunye nokufana
• Uluhlu olubanzi lwezicelokuzo zonke iifoam, ii-elastomers, kunye neengubo
• Ifanelekile kwiifomyula ezisekelwe kwi-HFO, ukunciphisa impembelelo yokusingqongileyo

Ezi mpawu zenza i-MXC-5 ibe yinto ekhethwayo kubavelisi abajonge ukwenzayenza ngcono ukusebenza, inciphise iindleko, kwaye iqinisekise ukuguquguquka kokwenziwa.

Isiphelo

I-PMDETA (Inombolo ye-CAS 3030-47-5), yiimfundo ephakamileyo esebenzayo kakhuluisincedisi se-aminengezicelo ezibanzi kwiamashishini e-polyurethane kunye ne-polymerAmandla ayo okusebenza njengei-catalyst kunye ne-ligandkwenza kube yimfuneko ekuveliseniamagwebu aqinileyo, ii-elastomers, ii-thermoplastics, kunye neenguboeneempawu zokusebenza ezigqwesileyo.

Ngenxa yokusabela okunamandla, ukunyibilika okugqwesileyo, kunye neziphumo ezihambelanayo, i-PMDETA (MXC-5) iyaqhubeka nokudlala indima ebalulekileyo ekuphuculeniubuchwepheshe be-polyurethane banamhlanje— ukusukaizixhobo zokukhusela ezisebenzisa amandla ombane kakuhle to iingubo zoshishino ezihlala ixesha elide.
