Ibhodi lokufakwa kwe-phenolic eliguquliwe lenziwe ngegwebu le-phenolic.Izingxenye zayo eziyinhloko yi-phenol ne-formaldehyde.Igwebu le-Phenolic wuhlobo olusha lwezinto ezingavimbeli ilangabi, ezingashi kanye nentuthu ephansi (ngaphansi kwezimo ezilinganiselwe).Yenziwe nge-phenolic resin ene-foaming agent, igwebu eliqinile lamaseli avaliwe elenziwe nge-ejenti yokwelapha nezinye izithasiselo.Igwebu le-Phenolic liyi-phenolic resin njengento eluhlaza eyinhloko, enezela i-ejenti yokwelapha, i-ejenti enegwebu nezinye izingxenye ezisizayo, kuyilapho i-resin ixhumene futhi iqinisiwe, i-ejenti enegwebu ikhiqiza igesi ehlakazekile kuyo futhi ifakwe amagwebu ukuze yenze igwebu.Ibhodi lokufakwa kwe-phenolic eliguquliwe linezinto eziningi ezinhle kakhulu:
(1) Inesakhiwo esinamaseli avaliwe afanayo, i-thermal conductivity ephansi, nokusebenza kwe-thermal insulation okulingana ne-polyurethane, engcono kune-polystyrene foam;
(2) Ngaphansi kwesenzo esiqondile selangabi, kuba khona ukwakheka kwekhabhoni, akukho ukuconsa, akukho ukugoqa, futhi akukho ukuncibilika.Ngemuva kokuthi ilangabi lishise, kwakhiwa ungqimba lwe-"graphite foam" ebusweni, okuvikela ngokuphumelelayo isakhiwo segwebu kungqimba futhi simelane nokungena komlilo.Isikhathi singafika ku-1 h;
(3) Ububanzi bokusebenza bukhulu, bufika ku -200～200 ℃, futhi bungasetshenziswa isikhathi eside ku-140～160 ℃;
(4) Ama-athomu e-phenolic ane-athomu yekhabhoni, i-hydrogen, ne-oxygen kuphela.Uma zibola ezingeni lokushisa eliphezulu, awekho amanye amagesi anobuthi ngaphandle kwenani elincane le-CO. Ubuningi bentuthu obuphezulu bungama-5.0%;
(5) Ngaphezu kokugqwala ama-alkali aqinile, igwebu le-phenolic lingamelana cishe nawo wonke ama-asidi angaphili, ama-asidi aphilayo, nezinyibilikisi zemvelo.Ukuchayeka elangeni isikhathi eside, akukho mkhuba osobala wokuguga, uma kuqhathaniswa nezinye izinto eziphilayo ezishisayo, impilo yayo yesevisi yinde;
(6) Inesakhiwo esihle samangqamuzana avaliwe, ukumuncwa kwamanzi aphansi, ukungena okuqinile okunqanda umhwamuko, futhi akukho ukujiya ngesikhathi sokugcinwa okubandayo;
(7) Usayizi uzinzile, izinga lokushintsha lincane, futhi izinga lokushintsha usayizi lingaphansi kuka-4% phakathi kwebanga lokushisa lokusetshenziswa.
Ibhodi eliguquliwe le-phenolic elingangenwa umlilo seliyinsizakalo yokusetshenziswa kwalo njengento efaka ukushisa kanye nempahla yokwakha engayingeni ilangabi.Isetshenziswa kabanzi ezinhlelweni zokuvikela odongeni zangaphandle: izinhlelo zokukhonkoloza ezincanyana zezindonga zangaphandle, ukufakwa kwezindonga zamakhethini engilazi, ukufakwa kokuhlobisa okuhlobisa, ukufakwa odongeni lwangaphandle namabhande okuvikela umlilo, njll.
