Indima ephambili kunye nohlalutyo lobuchwephesha lwee-catalysts ze-polyurethane ekuvelisweni kwezinto zokukhusela i-spray foam

Umgaqo wokuvelisa izinto zokukhusela i-spray foam

I-Spray Foam Insulation (SPF) sisixhobo sokukhusela ubushushu esiphucukileyo esenziwe ngokulawula ngokuchanekileyo indlela esebenza ngayo ikhemikhali yezinto ezimbini ezibalulekileyo zolwelo, i-polyol resin kunye ne-isocyanate. Xa ezi zinto zimbini zixutywe kwisixhobo esikhethekileyo sokutshiza, kwenzeka i-polymerization reaction ekhawulezayo phantsi kwesenzo se-catalyst, kwaye igesi ye-carbon dioxide ikhutshwa ngaxeshanye, nto leyo ebangela ukuba umxube wande amaxesha angama-30-60 kwimizuzwana embalwa, ekugqibeleni yenze i-polyurethane foam eneempawu ezibalaseleyo zokukhusela ubushushu.
Eyona nto iphambili kule nkqubo yeekhemikhali kukongeza i-polymerization reaction ye-isocyanate (-NCO) kunye ne-polyol (-OH), kunye ne-foam reaction ye-isocyanate kunye namanzi ukuvelisa i-carbon dioxide. Ibhalansi yezi mpendulo zimbini zikhuphisanayo imisela ngokuthe ngqo ukusebenza kokugqibela kwe-foam, kwaye kulapho kanye ii-polyurethane catalysts zidlala khona indima ebalulekileyo.

Ukusebenza kakuhle kakhuluI-MXC-BDMAisikhuthazi

I-MXC-BDMA yethu (N,N-dimethylbenzylamine, CAS 103-83-3) sisincedisi se-amine esisebenza kakuhle kakhulu esilungiselelwe i-polyurethane rigid foam, esibonisa iingenelo ezininzi zobugcisa ekuveliseni izixhobo zokukhusela i-spray foam:

1. Ulawulo oluchanekileyo lokuphendula

- Ibonelela ngokulinganisela okufanelekileyo kwempendulo ye-foam/gelling
- Iqinisekisa ukuba ijika lihlala lizinzile kwaye ixesha lokuphola lihlala lizinzile
- Iyakwazi ukumelana nobushushu obuhlukeneyo kunye neemeko zomswakama

2. Umgangatho ogqwesileyo wefoam

- Yenza isakhiwo seeseli ezivaliweyo esifanayo nesincinci (umlinganiselo weeseli ezivaliweyo >90%)
- Iphucula ukugeleza kwegwebu kwangoko kwaye iqinisekisa ukuzaliswa ngokupheleleyo
- Yomeleza amandla okubopha phakathi kwefoam kunye neziseko ezahlukeneyo

3. Iingenelo zenkqubo

-Ifanelekile kwiinkqubo zokwenziwa komxholo oqinileyo
- Iyahambelana neendidi ezahlukeneyo zeearhente zokuvuthela (i-HFC, i-HFO, amanzi, njl.njl.)
- Yehlisa ivumba eliqhelekileyo le-amine kwaye iphucula indawo yokwakha

Isikhanyisiicebo lokukhetha inkqubo

Xa kusenziwa i-spray foam, ukukhethwa kwee-catalysts kufuneka kuqwalaselwe ezi zinto zilandelayo zibalulekileyo:
1. Iimeko zemozulu: impembelelo yobushushu kunye nokufuma kwimpendulo
2. Iimpawu ze-substrate: iimfuno zokubopha kwi-substrate ezahlukeneyo ezifana nesinyithi, umthi, ikhonkrithi, njl.
3. Inkqubo yokwakha: umahluko phakathi kokutshiza ngesandla kunye nemveliso eqhubekayo yoomatshini
4. Izalathisi zokusebenza: iimfuno ezithile ezifana nokuqhuba ubushushu, ukuvuleka okuvaliweyo, kunye novavanyo lomlilo
I-MXC-BDMA ingasetyenziswa kunye nee-organic metal catalysts (ezifana ne-stannous octoate) ukuze kuphuculwe ngakumbi i-reaction kinetics ngokusebenzisa iziphumo ze-synergistic. Izisombululo zobugcisa esizicebisayo ziquka:
- Ukhuselo lwangaphandle lwesakhiwo: I-MXC-BDMA yinkqubo ephambili yokukhusela ukuqinisekisa ukuphiliswa ngokukhawuleza
- Ukufakwa kobushushu kwindawo ebandayo: inkqubo ye-composite catalyst yokuphucula izinga leeseli ezivaliweyo kunye nozinzo olulinganayo
- Ukufakwa kwepayipi yemizi-mveliso: ifomula ekhethekileyo yokuziqhelanisa nolwakhiwo oluntsonkothileyo lomphezulu ogobileyo
