Ubuchwepheshe bepaneli yesandwich yanamhlanje kunye nezixhobo eziphambili ze-polyurethane
Njengento entsha ebalulekileyo kwishishini lokwakha, iiphaneli zesandwich ze-polyurethane ziye zaba zezona zinto zikhethwayo kwizityalo zoshishino, indawo yokugcina izinto ezibandayo, iiworkshops ezicocekileyo kunye nezinye izakhiwo. Le nto idibeneyo equlathe iileya ezimbini zeephaneli zesinyithi kunye nesiseko se-polyurethane foam embindini ixhomekeke kakhulu kwinkqubo ye-polyurethane catalyst yobungcali ngenxa yokusebenza kwayo okugqwesileyo. Ii-catalysts zethu ze-MXC series zilungiselelwe ngokukodwa ukuveliswa kweephaneli zesandwich, ezinokuphucula kakhulu umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso.
Inkqubo yeCatalyst yeepaneli zesandwich
Iingenelo ezikhethekileyo zeI-MXC-37 (i-DMAEE)isikhuthazi
I-MXC-37 (2-(2-(dimethylamino)ethoxy)ethanol, i-CAS 1704-62-7) sisiqalelo se-amine esiguqulayo esizisa iimpumelelo ezininzi kwimveliso yeepaneli zesandwich:
- Iimpawu ezingenayo ivumba eliphantsi, ezingenayo ivumba eliphantsi: ukusombulula ingxaki yevumba lee-catalysts ze-amine zemveli kunye nokuphucula imeko yemveliso
- Umsebenzi wokwenza igwebu eliphezulu: ifanelekile ngakumbi kwimixube enamanzi amaninzi ukuqinisekisa ukwanda ngokupheleleyo kwegwebu
- Imo yokusetyenziswa kabini: ingasetyenziswa yodwa njengesixhobo esiphambili okanye xa idibene ne-BDMAEE
- Ukuhambelana okubanzi: kufanelekile kwiinkqubo ezahlukeneyo zepolyester kunye nepolyether polyol
Kumgca wemveliso oqhubekayo weephaneli zesandwich, i-MXC-37 inokubonelela nge-response curve ezinzileyo ukuqinisekisa ukufana kunye nokuhambelana kwezinto ezingundoqo zefoam, nto leyo ebalulekileyo ukuqinisekisa ukuba iiphaneli zesandwich zithe tyaba kwaye zizinzile ngobukhulu.
Inkqubela phambili kwezobuchwephesheI-MXC-15(isisombululo se-potassium octanoate)
I-MXC-15 (CAS 3164-85-0), njenge-catalyst esebenzayo ye-isocyanurate, inika inkxaso ephambili ekuvelisweni kweepaneli zesandwich ze-PIR:
- Izinga lokuguqulwa eliphezulu kakhulu: likhuthaza ukwenziwa kwe-isocyanate trimerization kwaye liphucula uzinzo lobushushu be-foam
- Isebenza kwifomula ye-viscosity ephezulu: yenza ngcono ukuchaneka kunye nokulingana kwempendulo kwiinkqubo zomxholo ophezulu oqinileyo
- Eyongayo nesebenzayo: ubungakanani obuncinci bokongeza bunokufezekisa isiphumo esihle kakhulu sokutsala amandla
- Inkqubo yePIR ehambelanayo yobungcali: eyenzelwe ngokukodwa iiphaneli zesandwich zepolyisocyanurate
I-MXC-15 inokuphucula kakhulu ukumelana nomlilo kunye nokuzinza kobukhulu beepaneli zesandwich, ukuze zikwazi ukugcina iipropati zoomatshini ezintle kakhulu kwiindawo ezinobushushu obuphezulu.
Indima ephambiliiikhatalystkwimveliso yeepaneli zesandwich
Kwinkqubo yokuvelisa iiphaneli zesandwich ze-polyurethane, inkqubo ye-catalyst ichaphazela ngokuthe ngqo ezi mpawu zilandelayo ziphambili:
1. Ukunyibilika kwegwebu: qinisekisa ukuba izinto ezikrwada ziyazalisa ngokupheleleyo umngxuma ophakathi kweephaneli ukuze kuthintelwe ukunqongophala kwezinto
2. Isantya sokunyanga: fanisa iimfuno zesantya zomgca wemveliso oqhubekayo ukuze kwandiswe amandla emveliso
3. Ulwakhiwo lweseli: luchaphazela ukuhanjiswa kobushushu kunye namandla oomatshini epaneli yesandwich
4. Ukusebenza kokuncamathela: kumisela amandla okudibanisa ujongano phakathi kwezinto eziphambili kunye nephaneli
5. Uzinzo lobukhulu: luthintela ukuguquguquka kwephaneli okubangelwa kukuncitshiswa kwefoam
