Ko te papa whakamatao phenolic kua whakarereketia he mea hanga ki te pahuka phenolic.Ko ona waahanga matua ko te phenol me te formaldehyde.Ko te pahuka Phenolic he momo hou mo te mura-muri, te ahi, me te iti-paowa marara (i raro i nga tikanga iti).He mea hanga ki te kapia phenolic me te kaihoko hukahuka, Te pahuka i te pūtau kati i hangaia e te kaihoko whakaora me etahi atu taapiri.Ko te pahuka Phenolic he kapia phenolic hei rauemi mata matua, te taapiri i te kaihoko rongoa, te kaihoko hukahuka me etahi atu waahanga awhina, i te wa e hono ana te kapia me te whakakoi, ka whakaputahia e te kaihoko hukahuka te hau kua marara ki roto, ka pahuka ki te hanga i te pahuka.He maha nga ahuatanga pai o te papa whakamatao ahi phenolic kua whakarereketia:
(1) He rite tonu te hanganga o nga pūtau kati, he iti te kawe i te waiariki, me te mahi whakamaarama waiariki e rite ana ki te polyurethane, he pai ake i te pahuka polystyrene;
(2) I raro i te mahi tika o te mura, he hanga waro, kahore he pupuhi, kahore he koiri, kahore he rewa.Whai muri i te mura o te mura, ka hangaia he paparanga "graphite foam" ki runga i te mata, e tiaki pai ana i te hanga pahuka i roto i te paparanga me te aukati i te urunga o te mura.Ka taea te wa ki te 1 h;
(3) He nui te whānuitanga o te tono, tae atu ki te -200～200 ℃, ka taea te whakamahi mo te wa roa i te 140～160 ℃;
(4) Ko nga ngota ngota phenolic anake he waro, hauwai, me te ngota hāora.Ka pirau i te wera nui, karekau he hau paitini engari he iti noa te CO. Ko te 5.0% te teitei o te paoa auahi;
(5) I tua atu i te waikurahia e te kawakore kaha, ka taea e te pahukahu phenolic te tu tata ki nga waikawa pararopi katoa, waikawa waro, me nga whakarewa waro.Ko te wa-roa ki te ra, kaore he ahuatanga o te koroheketanga, ka whakatauritea ki etahi atu rauemi whakawera waiariki, he roa ake te ora o tana mahi;
(6) He pai te hanganga o te pūtau kati, te iti o te whakauru o te wai, te kaha o te whakauru anti-kohu, me te kore e pupuhi i te wa o te rokiroki makariri;
(7) He pumau te rahi, he iti te tere o te huringa, a ko te tere o te huringa rahi he iti iho i te 4% i roto i te awhe pāmahana whakamahinga.
Ko te poari whakaraerae ahi phenolic kua whakarereketia kua waiho hei kaupapa matua mo tana tono hei whakamaarama wera me nga mea hanga mura ahi.Kei te whakamahia nuitia i roto i nga punaha whakaraerae taiepa o waho: nga punaha raima angiangi mo nga pakitara o waho, te whakamarumaru taiepa arai karaehe, te whakamaarama whakapaipai, te whakamaarama o te pakitara o waho me nga whitiki whakamaarama ahi, etc.
