Iiphaneli zesandwich zibe sisiseko sokwakhiwa kwanamhlanje, zibonelela ngobushushu obugqwesileyo, amandla olwakhiwo kunye nokonga amandla. Embindini wezi paneli kukho i-polyurethane foam, into exhomekeke ekusebenzeni kwayo ngenxa ye-catalyst efanelekileyo. KwaMingxu Chemical, sigxile kwi-polyurethane catalysts eziphambili ukuze siphucule ukuveliswa kweepaneli zesandwich, siqinisekisa umgangatho ophezulu kunye nokusebenza kakuhle.
Kule nqaku, sihlola indima ephambili yee-polyurethane catalysts ekwenzeni iipaneli zesandwich kunye nendlela izisombululo zethu ezinokukunceda ngayo ukufezekisa iziphumo ezibalaseleyo.
Yintoni iphaneli yesandwich?
Iipaneli zesandwich zizinto ezidityanisiweyo eziqulathe iileya ezintathu:
1. Iileya ezimbini zangaphandle (ii-facers): Ngokwesiqhelo zenziwe ngesinyithi, iplastiki okanye umthi, zibonelela ngamandla nokhuseleko lwesakhiwo.
2. Umaleko ongundoqo: Ngokwesiqhelo wenziwe nge-polyurethane foam, ene-thermal insulation egqwesileyo kunye neempawu ezikhaphukhaphu.
Ezi paneli zisetyenziswa kakhulu ekwakheni, kwindawo yokugcina izinto ezibandayo, ekwakheni nasekuthuthweni kwemizi-mveliso ngenxa yokuqina kwazo, ukonga umbane kunye nokulula kokufakwa kwazo.
Indima yee-polyurethane catalysts ekuvelisweni kweepaneli zesandwich
I-polyurethane foam sisithako esibalulekileyo kwiipaneli zesandwich, kwaye ukusebenza kwayo kuxhomekeke kakhulu kwi-catalyst esetyenziswa kwinkqubo yemveliso. Ii-catalysts zidlala indima ebalulekileyo koku kulandelayo:
1. Ukulawula izinga lokusabela: IiCatalysts zilawula impendulo phakathi kweepolyols kunye nee-isocyanates, ziqinisekisa ukwanda kunye nokuphiliswa kwefoam okufanelekileyo.
2. Ukuqinisa ulwakhiwo lwe-foam: Zinceda ekwakheni ulwakhiwo lweseli olufanayo, oluphucula ubushushu kunye neempawu zoomatshini ze-foam.
3. Ukuphucula ukunamathela: IiCatalysts ziqinisekisa unxibelelwano oluqinileyo phakathi kwesiseko sefoam kunye nomaleko ongaphandle, nto leyo ephucula ukuqina kwephaneli.
4. Ukuphucula ixesha lokucubungula: Ngokukhawulezisa okanye ukulibazisa iimpendulo ezithile, ii-catalysts zivumela abavelisi ukuba balungise ukusebenza kakuhle kwemveliso.
