Ii-catalysts ze-polyurethane zidlala indima ebalulekileyo ekwenziweni kweepaneli zesandwich, iifreyimu zefenitshala ye-foam eqinileyo kunye nezinto zokuhombisa, ezinokuphucula ukusebenza kakuhle kunye nokusebenza kwe-polyurethane foam. Ii-catalysts ezisetyenziswa kwezi zicelo yi-MXC-8 (DMCHA) kunye ne-MXC-41, zombini ezivumela ukuveliswa kwee-foams ezihlala ixesha elide, ezikhaphukhaphu kunye nezisebenza kakuhle.
I-MXC-8 (DMCHA):Isincedisi Esisebenzayo Sokusetyenziswa Kwefoam Eqinileyo
I-MXC-8, kwaziwa njengeI-DMCHA(Dimethylcyclohexylamine), sisithako esisebenza kakuhle kakhulu esisekelwe kwi-amine esisetyenziswa kakhulu ekuveliseni amagwebu e-polyurethane aqinileyo, kuqukaiiphaneli zesandwichkwayeiifreyimu zefenitshala.
Iingenelo eziphambili ze-MXC-8 (DMCHA) kwiMveliso yeFoam:
Ixesha Lokunyanga Elikhawulezayo: I-DMCHA ikhawulezisa inkqubo yokunyanga iinkqubo ze-polyurethane, inceda abavelisi ukuba bafikelele kwixesha elikhawulezayo lokuguqula imveliso ye-foam eqinileyo, efanaukwenziwa kweefreyimu zefenitshala.
Ulwakhiwo lweFoam oluphuculweyo: I-MXC-8 iphucula ukwakheka kweeseli ezincinci nezifanayo kwi-foam, nto leyo ephuculaamandla oxinzelelo kwayeuzinzo olunemilinganiselo yemveliso yokugqibela. Oku kubalulekile kwizicelo ezifana neefreyimu zefenitshala yefoam eqinileyo, apho ukuqina kwesakhiwo kubalulekile ekuqinisekiseni ukuqina kunye nobomi benkonzo.
Ukuguquguquka kwizicelo: Ukongeza kwiipaneli zesandwich, iMXC-8 ikwasetyenziswa nakwezinye iindawo zefoam zokuhombisa, inceda ukuvelisa izinto ezilula kodwa ezomeleleyo zokuyila ifenitshala kunye nezinto zokwakha. Iyanyibilika kwiipolyol ezininzi kunye nezinyibilikisi zendalo, kodwa ngokusisiseko ayinyibiliki emanzini. Ingasetyenziswa njengesincedisi kwiintlobo ngeentlobo zezicelo kuquka zonke iintlobo zefoam zokupakisha eziqinileyo.
Inkunkuma Encitshisiweyo kunye NokungaguquguqukiNgokukhawulezisa impendulo phakathii-polyolkwayeisocyanateKwizinto ezisetyenziswa kwi-MXC-8, i-MXC-8 inceda ukugcina iipropati ze-foam zihambelana, inciphisa inkunkuma kwaye iqinisekisa ukufana kwimveliso yokugqibela.
I-MXC-41:Amandla Aphezulu Okukhupha Igwebu Kwiinkqubo Zokuxhasana Ngamanzi
Esinye isikhuthazi esibalulekileyo ekuvelisweni kwamagwebu e-polyurethane aqinileyo, ingakumbi kwiiiphaneli zesandwich, yiI-MXC-41. Eyaziwa ngokuba namandla ayo abalaseleyo okukhupha igwebu, i-MXC-41 isebenza kakhulu kwi-iinkqubo eziqinileyo ezihambelana namanzi, apho amanzi asetyenziselwa ukudalaI-CO2igesi, ekhuthaza ukwanda kwegwebu ngexesha lenkqubo yokunyanga.
Iingenelo eziphambili ze-MXC-41 kwiMveliso yeFoam:
Ubuchule obuGqibeleleyo bokuGxotha: I-MXC-41 isebenza kakuhle kwiinkqubo ezisebenzisa amanzi njengesixhobo sokukhupha igwebu, iqinisekisa ukwanda kwegwebu okusebenzayo nokulinganayo. Lo mthamo wokukhupha igwebu ubalulekile ekuvelisweni kweepaneli zesandwich, njengoko ulwakhiwo lweseli olufanayo lubalulekile kokubini ekugqumeni ubushushu kunye namandla oomatshini.
Iipropati zeZakhiwo eziphuculweyo: Iimpawu zokukhupha amagwebu ze-catalyst zinceda ekuveliseni amagwebu aqinileyo angapheleli nje ekubunzimeni kodwa akwanazo namandla okuthwala umthwalo omkhulu kunye namandla okucinezela, nto leyo eyenza ukuba abe lukhetho olubanzi lokusetyenziswa kwezakhiwo ezifana neepaneli zesandwich kunye neefreyimu zefenitshala.
Izicelo kwiiSandwich Panels kunye neeFanitshala Frames
Iiphaneli zeSandwichZombiniI-MXC-8 (i-DMCHA)kwayeI-MXC-41zibalulekile kwimvelisoiiphaneli zesandwich, equlathe isiseko sefoam esiqinileyo esibekwe phakathi kweengqimba ezimbini zezinto (ngesiqhelo isinyithi okanye iplastiki). Ezi paneli zisetyenziswa kakhulu ekwakheni, ekugqumeni nasekuthuthweni ngenxaiipropati zokukhusela ubushushukwayeamandla oomatshini. I-MXC-8 inceda ekufezekiseniukunyanga ngokukhawulezakwayeukwakheka kwefoam okuzinzileyo, ngelixa iMXC-41 iqinisekisa ukuba i-foamukusebenza kakuhle kokwenza amagwebukunye nokuthembeka kwesakhiwo ngokubanzi.
Iifreyimu zefenitshala yeFoam eqinileyo: Iamagwebu aqinileyoisetyenziswa kwiiifreyimu zefenitshalaZiyazuza kwiipropati zoomatshini ezikhawuleza ukubola kunye nezomeleleyo ezibonelelwa yi-MXC-8. Ezi propati zivumela ukwenziwa kwezinto zefenitshala ezikhaphukhaphu, ezomeleleyo nezisebenzayo nezinomtsalane.
Iindawo zokuhombisaUkongeza kwizicelo zesakhiwo, i-MXC-8 kunye ne-MXC-41 nazo ziyasetyenziswa ekudalweniiindawo zefoam zokuhombisayefenitshala kunye noyilo lwangaphakathi. Ukuguquguquka kwezi catalysts kuqinisekisa ukuba ifoam ihlala iphezuluumgangatho wokubonwayongelixaekhaphukhaphukwayeyomelelayo.
Isiphelo
Ukusetyenziswa kwee-catalysts ze-MXC-8 (DMCHA) kunye ne-MXC-41 ekuveliseni iiphaneli zesandwich, iifreyimu zefenitshala ye-foam eqinileyo kunye nezinto zokuhombisa kuphucula ukusebenza, ukuqina kunye nokusebenza kakuhle kweenkqubo ze-polyurethane foam. Zizonke, ezi catalysts zibalulekile ekwenzeni ii-foams ezisebenza kakhulu ezihlangabezana neemfuno ezifunekayo zamashishini okwakha, ifenitshala kunye noyilo lwanamhlanje.
