Oku kuphucula amandla egwebu okugcina intuthuzelo, ngakumbi kwiindawo zokuhlala kunye nezicelo zokulala apho ukuhamba komoya kubalulekile.
- Ukuguqulwa koxinzelelo oluphantsi: Enye into ebalulekileyo kwiifoam eziguquguqukayo kukuxhathisa iseti yokucinezelwa, okubhekiselele kumandla efoam okugcina imo yayo yokuqala emva kokusetyenziswa ixesha elide. Ukukhetha okufanelekileyo kwee-catalysts kunciphisa ukuguquguquka kokucinezelwa, kuqinisekisa ukuba ifoam igcina imo yayo kunye nokusebenza kwayo ngokuhamba kwexesha, nokuba iphantsi koxinzelelo oluphindaphindwayo.
I-MXC-DPA:Isihluzi-mveliso esincinci esine-Gelation ephezulu kunye nokunyibilika kwamanzi
Enye yezinto ezibangela umdla kakhulu kwindima yayo ekuveliseni amagwebu aguquguqukayo asebenza kakuhle yileI-MXC-DPA. Le catalyst yindlela yokukhupha ukungcola okuncinci, nto leyo eyenza ukuba ifaneleke kakhulu xa kusetyenziswe impembelelo yokusingqongileyo kunye nomgangatho womoya wangaphakathi. Ukongeza ekubeni inobuhlobo nokusingqongileyo, i-MXC-DPA inika iipropati ezibalaseleyo zokugaya, inegalelo ekwakhiweni nasekusasazweni kweeseli zefoam ngokufanelekileyo. Ukutyibilika kwayo okuphezulu kuqinisekisa inkqubo yokuvelisa egudileyo, kunciphisa imiba enxulumene nokungangqinelani kwisakhiwo sefoam.
Ukudibanisa kwe-MXC-DPA ukukhutshwa okuphantsi kunye nokusebenza okuphezulu kwenza kube yinto eguquguqukayo yokusetyenziswa kwi-foams eziguquguqukayo apho ukhuseleko kunye nomgangatho kubaluleke kakhulu.
I-MXC-T9:Ukulinganisela Impendulo kunye neempawu eziphantsi zevumba
Kwiindlela ezininzi zokwenziwa kwe-foam eziguquguqukayo, ukufezekisa ibhalansi efanelekileyo phakathi kwe-reactivity kunye neempawu zokugqibela ze-foam kubalulekile.I-MXC-T9Isebenza njenge-co-catalyst enefuthe elikhulu kwimpendulo iyonke. Iyaphucula inkqubo ye-gelling ngelixa isebenza njenge-gel amine catalyst, iqinisekisa ukuba impendulo ye-polyurethane iqhubeka ngesantya esifanelekileyo.
Inzuzo ephawulekayo ye-MXC-T9 kukuba ayinavumba lininzi, nto leyo eyenza ukuba ifaneleke kakhulu xa kusetyenziswa apho ukulawula ivumba kubalulekile, njengakwiibhedi, izihlalo, kunye nangaphakathi kweemoto. Ikwanceda ukugcina ukuthembeka kwefoam kunye nozinzo ngexesha lokwenziwa kwayo, nto leyo enegalelo ekuqineni nasekuqineni kwefoam ixesha elide.
