Imeko yangoku yetekhnoloji yokukhusela i-spray foam
Izixhobo zokukhusela i-polyurethane spray foam ziye zaba yiteknoloji ephambili kwiiprojekthi zanamhlanje zokonga amandla ezakhiwo. Ngenxa yokusebenza kwayo okuhle kakhulu kokukhusela ubushushu kunye neempawu zokwakha ezingenamthungo, ithatha indawo ebalulekileyo kwimarike yehlabathi yokukhusela ubushushu bezakhiwo. Le teknoloji yokwenza indawo itshiza umxube we-isocyanate kunye ne-polyol ngqo kumphezulu we-substrate, kwaye isabela ngokukhawuleza phantsi kwesenzo se-catalyst ukwenza isakhiwo se-closed-cell okanye se-open-cell foam ukuze kufezekiswe isiphumo esihle kakhulu sokukhusela ubushushu.
Ifoam yokutshiza iiseli ezivaliweyo iye yaba sisisombululo esithandwayo sokukhusela iindonga zangaphandle zesakhiwo, uphahla kunye nendawo yokugcina izinto ebandayo ngenxa yokusebenza kwayo okuhle kakhulu kokukhusela ubushushu (ukuqhuba ubushushu obuyi-0.020-0.028W/(m·K)) kunye neempawu zokuqinisa ulwakhiwo. Isitshixo sokufezekisa oku kusebenza kakuhle sikwindlela echanekileyo yokulawula inkqubo ye-catalyst ye-trimerization reaction ye-polyisocyanurate.
Impumelelo yobugcisaI-MXC-TMAisikhuthazi
I-MXC-TMA catalyst sisizukulwana esitsha se-trimerization catalyst eyenzelwe ngokukodwa i-spray foam. Ifomula yayo entsha isombulula iingxaki ezininzi zobugcisa ze-catalysts zemveli ezisekelwe kwi-potassium ngexesha lokwakhiwa. Le mveliso yolwelo engenambala ukuya kwephuzi elikhanyayo ifezekisa ulawulo oluchanekileyo lwe-polyurethane reaction kinetics ngokusebenzisa ukwakheka kwayo okwahlukileyo kweekhemikhali.
Ngokuphathelele ulawulo lokuphendula, i-MXC-TMA ibonelela ngegophe elinyukayo elifanayo nelilawulekayo, elinciphisa ngempumelelo ukwenzeka kokuwa ngexesha lokwakhiwa kokutshiza. Izixhobo zayo ezisebenzayo ezikhethekileyo zilungelelanisa ukusabela kwe-foam kunye ne-gelling, ziphepha ukuveliswa kweziphene zomphezulu, ngelixa ziphucula isantya sokuphiliswa kwaye zinciphisa kakhulu ixesha lesithuba sokwakha.
Ukuphucula ukugeleza kwamanzi yenye inzuzo enkulu yobuchwepheshe be-MXC-TMA. Le mveliso inokuphucula kakhulu iimpawu zokuhamba kweefomyula zomxholo oqinileyo kwaye ifezekise ukusasazwa kwefoam okufanayo, okufanelekileyo ngokukodwa ukwakhiwa kokutshiza kwiindawo ezintsonkothileyo zejometri. Xa kuthelekiswa nee-catalysts zemveli ezisekelwe kwi-potassium, i-MXC-TMA isenokugcina umsebenzi omhle wokusabela kwiindawo ezishushu eziphantsi, yandisa kakhulu uluhlu lokusetyenziswa kobushushu bokwakha.
Imigaqo yobugcisa kunye neenzuzo zokusebenza
I-MXC-TMAIkhuthaza ukusabela kwe-trimerization ye-isocyanates ukwenza isakhiwo sendandatho ye-isocyanurate esizinzileyo. Olu lwakhiwo lukhethekileyo lweekhemikhali lunika izinto ze-foam iingenelo ezintathu eziphambili: uzinzo lobushushu oluphuculweyo kakhulu, ubushushu bokubola bunokwandiswa ngama-30-50℃; ukumelana okuhle komlilo, isalathisi seoksijini sinokufikelela kuma-26-28; uzinzo oluhle kakhulu lobukhulu, izinga lokutshintsha komthamo lilawulwa ngaphakathi kwe-1%.
Kwimisebenzi ebonakalayo, sicebisa ukusetyenziswa kwe-MXC-TMA kunye nee-amine catalysts, kunye nomlinganiselo olawulwa kwi-30-50% ye-catalyst iyonke. Imveliso inoluhlu olubanzi lobushushu bokusebenza (15-35℃), iyahambelana neendidi ezahlukeneyo zee-agents ezikhupha amagwebu ezifana ne-HFC-245fa kunye ne-HFO-1234ze, kwaye ingasetyenziswa kunye nee-polyether/polyester polyols ezininzi kunye ne-flame retardants.
Inkxaso yobugcisa kunye nesiqinisekiso senkonzo
Sinikezela ngenkxaso yobugcisa epheleleyo kubavelisi be-spray foam behlabathi kunye neenkampani zokwakha, kubandakanya iinkonzo zovavanyo lwelebhu, isikhokelo sokwenza ngcono umgca wemveliso kunye nezisombululo zophuhliso ezenzelwe wena. Iqela lobuchwephesha elinobuchwephesha linokubonelela ngezisombululo zenkqubo ye-catalyst ezenzelwe wena ngokusekelwe kwizixhobo ezithile zomthengi kunye neemeko zenkqubo.
Ngokuphathelele inkqubo yokuqinisekisa umgangatho, siphumeza ngokungqongqo imigangatho yemveliso eqinisekisiweyo ye-ISO 9001 ukuqinisekisa ukuba uzinzo lwebhetshi yemveliso ludlula i-99%. Inethiwekhi yokubonelela ngeenkonzo zehlabathi inokukwazi ukuhlangabezana neemfuno zabathengi ezingxamisekileyo zeodolo kwaye iqinisekise inkqubela phambili yokwakhiwa kweprojekthi.
