Questo articolo mette a confronto il nostro pannello isolante nano microporoso con il silicato di calcio sui numeri che contano per un progettista: la conduttivit\u00e0 termica nell'intervallo di esercizio e cosa significa la differenza in termini di spessore e peso del rivestimento. Tutti i valori microporosi riportati di seguito sono valori misurati dal nostro pannello standard; i valori di confronto per silicato di calcio, fibra ceramica, lana di roccia e mattone isolante sono gli stessi dati di riferimento che pubblichiamo sulla <a href=\"https:\/\/anchor-microporous.com\/it\/piastra-standard\/\">pannello isolante standard in nano<\/a> pagina.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Confronto della conducibilit\u00e0 termica (W\/m\u00b7K)<\/h2>\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Temperatura media<\/th><th>Mattone isolante<\/th><th>Lana di roccia<\/th><th>Fibra ceramica<\/th><th>Silicato di calcio<\/th><th>Aria calma<\/th><th>Microporoso<\/th><\/tr><\/thead><tbody><tr><td>-100 \u00b0C<\/td><td>0.1180<\/td><td>0.0320<\/td><td>0.0300<\/td><td>0.0380<\/td><td>0.0160<\/td><td>0.0200<\/td><\/tr><tr><td>0 \u00b0C<\/td><td>0.1200<\/td><td>0.0330<\/td><td>0.0320<\/td><td>0.0400<\/td><td>0.0180<\/td><td>0.0210<\/td><\/tr><tr><td>100 \u00b0C<\/td><td>0.1220<\/td><td>0.0370<\/td><td>0.0360<\/td><td>0.0460<\/td><td>0.0200<\/td><td>0.0220<\/td><\/tr><tr><td>200 \u00b0C<\/td><td>0.1250<\/td><td>0.0550<\/td><td>0.0440<\/td><td>0.0550<\/td><td>0.0220<\/td><td>0.0210<\/td><\/tr><tr><td>300 \u00b0C<\/td><td>0.1300<\/td><td>0.0800<\/td><td>0.0600<\/td><td>0.0650<\/td><td>0.0250<\/td><td>0.0240<\/td><\/tr><tr><td>400 \u00b0C<\/td><td>0.1350<\/td><td>0.1200<\/td><td>0.0800<\/td><td>0.0800<\/td><td>0.0360<\/td><td>0.0240<\/td><\/tr><tr><td>500 \u00b0C<\/td><td>0.1440<\/td><td>0.1800<\/td><td>0.1100<\/td><td>0.0960<\/td><td>0.0440<\/td><td>0.0280<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n<h2 class=\"wp-block-heading\">Cosa significano i numeri in un rivestimento<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Su tutta la gamma, il pannello microporoso presenta una conduttivit\u00e0 pari a circa la met\u00e0 o un terzo di quella del silicato di calcio \u2014 a 500 \u00b0C, 0,0280 contro 0,0960 W\/m\u00b7K. Ne derivano due conseguenze pratiche. Primo, a parit\u00e0 di temperatura della faccia fredda, uno strato di supporto microporoso pu\u00f2 avere uno spessore pari alla met\u00e0 o a un terzo di uno strato di silicato di calcio, restituendo volume utile al recipiente. Secondo, a parit\u00e0 di spessore il mantello si mantiene pi\u00f9 freddo e la dispersione termica diminuisce di conseguenza. Il pannello \u00e8 anche pi\u00f9 leggero: la nostra gamma standard ha una densit\u00e0 di 220\u2013280 kg\/m\u00b3, quindi un rivestimento pi\u00f9 sottile di materiale pi\u00f9 leggero riduce in modo significativo il peso totale del rivestimento.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Dove il silicato di calcio ha ancora senso<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Il silicato di calcio rimane una scelta ragionevole dove \u00e8 richiesta una capacit\u00e0 portante meccanica nello strato isolante stesso, dove il budget domina la decisione e dove lo spessore aggiuntivo del rivestimento non costa nulla perch\u00e9 il recipiente \u00e8 gi\u00e0 costruito. Il pannello microporoso ha una bassa resistenza meccanica e deve essere protetto dall'impatto diretto della fiamma e dall'abrasione mediante uno strato refrattario di lavoro \u2014 la stessa regola che indichiamo nella pagina del nostro prodotto. \u00c8 un isolante di supporto, non un rivestimento di lavoro.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Guida alla selezione<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Scegliete il pannello microporoso quando lo spessore o il peso del rivestimento sono vincolati, quando gli obiettivi di temperatura del mantello o di dispersione energetica sono stringenti, o quando state eliminando un collo di bottiglia in un recipiente esistente senza ingrandire il mantello. Restate sul silicato di calcio quando l'isolante deve sopportare carichi meccanici o quando il costo iniziale \u00e8 l'unico criterio.
