Ibhodi yokugquma i-phenolic elungisiweyo yenziwe nge-phenolic foam.Amacandelo ayo aphambili yi-phenol kunye ne-formaldehyde.I-Phenolic foam luhlobo olutsha lwe-flame-retardant, i-fireproof kunye ne-low-smoke insulation material (phantsi kweemeko ezilinganiselwe).Yenziwe nge-phenolic resin ene-ejenti ephuma ugwebu, igwebu eliqinileyo elivaliweyo elenziwe nge-ejenti yokunyanga kunye nezinye izongezo.I-Phenolic foam yiresin ye-phenolic njengeyona nto iphambili ekrwada, yongeza i-ejenti yokunyanga, i-ejenti enogwebu kunye nezinye izinto ezincedisayo, ngelixa i-resin idityaniswe ngokunqamlezileyo kwaye yoqina, i-agent enegwebu ivelisa igesi esasazwe kuyo kwaye inegwebu ukwenza igwebu.Ibhodi yokugquma i-phenolic elungisiweyo ineempawu ezininzi ezintle:
(1) Inesakhiwo esifanayo se-cell evaliweyo, ukuhanjiswa kwe-thermal ephantsi, kunye nokusebenza kwe-thermal insulation efana ne-polyurethane, engcono kune-polystyrene foam;
(2) Ngaphantsi kwesenzo esithe ngqo somlilo, kukho ukubunjwa kwekhabhoni, akukho ukuvuza, akukho ukugoba, kwaye akukho kunyibilika.Emva kokuba ilangatye livutha, uluhlu lwe "graphite foam" lwenziwa phezu komhlaba, olukhusela ngokufanelekileyo ulwakhiwo lwe-foam kwinqanaba kwaye luchasa ukungena komlilo.Ixesha lingafikelela kwi-1 h;
(3) Umda wesicelo mkhulu, ukuya kuthi ga ku -200～200 ℃, kwaye ungasetyenziswa ixesha elide kwi-140～160 ℃;
(4) Iimolekyuli zephenolic zineeathom zekhabhoni, ihydrogen, kunye neoksijini kuphela.Xa zibolile kwiqondo lokushisa eliphezulu, azikho ezinye iigesi ezinobuthi ngaphandle kwexabiso elincinci le-CO. Ubuninzi bobuninzi bomsi yi-5.0%;
5Ukutshatyalaliswa kwexesha elide elangeni, akukho nto icacileyo yokuguga, xa kuthelekiswa nezinye izinto eziphilayo zokufakelwa kwe-thermal, ubomi bayo benkonzo bude;
(6) Inesakhiwo esilungileyo seseli evaliweyo, ukufunxwa kwamanzi aphantsi, ukungena okunamandla okuchasa umphunga, kwaye akukho ukujiya ngexesha lokugcinwa okubandayo;
(7) Ubungakanani buzinzile, izinga lokutshintsha lincinci, kwaye izinga lokutshintsha ubungakanani lingaphantsi kwe-4% ngaphakathi komgangatho wokushisa wokusetyenziswa.
Ibhodi yokugquma i-phenolic eguquliweyo yokugquma umlilo iye yaba yeyona nto iphambili kwisicelo sayo njengento yokugquma ubushushu kunye nesixhobo sokwakha esinganyangekiyo kwidangatye.Isetyenziswe ngokubanzi kwiinkqubo zokugquma iindonga zangaphandle: iinkqubo ezinqabileyo zokutyabeka kwiindonga zangaphandle, i-glass curtain wall insulation, i-decorative insulation, i-insulation wall yangaphandle kunye namabhanti okucima umlilo, njl.
