ngā purongo

Ngā matū whakapūkara phenolice rua ngā momo e whakarōpūtia ana i runga i ngā rerekētanga o ngā tukanga hanga:

Ngā Matū Whakarewa Pēhanga: Ka tukatukahia mā te whakarewa pēhanga, ka whakanohoia te rauemi ki roto i te pokepoke, ka tukuna ki te pāmahana me te pēhanga teitei (te tikanga 150-180°C, 10-50 MPa) kia pakari ai. He pai mō te hanga i ngā āhua uaua, ngā wāhanga e hiahia ana ki te tika o ngā āhuatanga, ngā wāhanga matotoru nui rānei pērā i ngā whāriki whakamahana i roto i ngā taputapu hiko me ngā wāhanga ātete wera huri noa i ngā miihini motuka. Mā te horapa ōrite o te whakakī, ka tukuna e ēnei he kaha miihini pai ake me te ātete pāmahana teitei. He whānuitia te whakamahinga i roto i ngā wāhanga ahumahi waenga-ki-teitei, ā, ko te momo hua matua tuku iho.

Ngā Matū Whakarewa Werohanga: He mea hanga mō ngā tukanga whakarewa werohanga, he tino pai ngā āhuatanga rere o ēnei rauemi. Ka tere te whakakī i ngā pokepokea, ka whakamaroke mā roto i ngā mīhini whakarewa werohanga, ka tuku i te pai o te whakaputa me te aunoatanga. He pai mō ngā wāhanga iti-ki-waenga te rahi e whakaputa papatipu ana me ngā hanganga ōrite, pērā i ngā panera pana mō ngā taputapu whare, ngā hononga hiko motuka, me ngā ārai hiko iti. Nā te whānui o te whakamahinga o te whakarewa werohanga me te rere rauemi kua arotauhia, kei te piki haere tonu te wāhi mākete o tēnei kāwai hua, inā koa te whakatutuki i ngā tono whakaputa tauine o ngā taonga ahumahi kaihoko.

Ngā Rohe Taupānga: Ngā Horopaki Whakatinanatanga Matua mōNgā Matū Whakarewa Phenolic

Ko ngā tono whakararo o ngā matū whakakikorua phenolic e tino arohia ana i roto i te hanga ahumahi, e whakarōpūtia ana ki ngā rāngai motuhake e whā:

Taputapu Hiko/Hiko: Ko te rohe tono matua ko ngā wāhanga ārai me ngā wāhanga hanganga mō ngā motuka, ngā whakawhiti hiko, ngā kaiwawao hiko, ngā whakawhiti hiko, me ngā taputapu rite. Hei tauira, ko ngā whakawhitiwhiti hiko, ngā matua ārai whakawhiti hiko, me ngā pūrua kaiwawao hiko. Ko te ārai teitei me te ātete wera o ngā kirihou whakarewa phenolic ka whakarite kia haumaru te mahi o ngā taputapu hiko i raro i ngā āhuatanga ngaohiko teitei me te wera nui, ka ārai i ngā ara iahiko poto i puta mai i te rahunga o te ārai. Ko ngā kirihou whakarewa kōpeketanga e whakamahia ana mō ngā wāhanga ārai nui, ko ngā kirihou whakarewa werohanga ia e pai ana mō te hanga papatipu o ngā wāhanga hiko iti.

Ahumahi Waka: Whakamahia i roto i ngā wāhanga ātete-wera mō ngā taputapu miihini motuka, ngā pūnaha hiko, me te anga, pērā i ngā gaskets pane rango miihini, ngā whare koiri mura, ngā whīra pūoko, me ngā wāhanga pūnaha parai. Me tu atu ēnei wāhanga ki te pāmahana miihini (120-180°C) me te wiri/pānga mō te wā roa. Ka tutuki i ngā kirihou whakarewa phenolic ngā whakaritenga me ō rātou ātete pāmahana teitei, ātete hinu, me te kaha miihini, me te tuku taumaha mama ake i ngā konganuku hei whakaiti i te papatipu waka me te whakapaunga wahie. He pai ngā kirihou whakarewa kōpeketanga mō ngā wāhanga matua miihini ātete-wera, ko ngā kirihou whakarewa werohanga ia e whakamahia ana mō ngā wāhanga hiko iti-ki-waenga.

Ngā Taputapu Kāinga: He pai mō ngā wāhanga hanganga me ngā wāhanga mahi ātete wera i roto i ngā taputapu pēnei i ngā oumu raihi, ngā oumu hiko, ngā ngaruiti, me ngā mīhini horoi. Hei tauira, ko ngā whāriki kohua o roto o te oumu raihi, ngā whakairinga huānga whakamahana oumu hiko, ngā wāhanga whakamahana kuaha ngaruiti, me ngā taupoki pito o te motuka mīhini horoi. Me tu atu ngā wāhanga taputapu ki ngā pāmahana reo-rahi ki te teitei (80-150°C) me ngā taiao makuku i te whakamahinga o ia rā. He nui ngā painga o ngā kirihou whakarewa phenolic i roto i te ātete ki te pāmahana teitei, te ātete ki te makuku, me te whai huatanga utu. Nā te pai o te whakaputa, kua noho ngā kirihou whakarewa werohanga hei whiringa matua i roto i te rāngai taputapu kāinga.

Ētahi atu Taupānga:Ngā kirihou i whakapūkarahia ki te phenolice whakamahia ana hoki i roto i te rererangi (hei tauira, ngā wāhanga whakamahana iti mō ngā taputapu o runga), ngā taputapu hauora (hei tauira, ngā wāhanga whakahoromata pāmahana teitei), me ngā takirere ahumahi (hei tauira, ngā nohoanga hiri takirere). Hei tauira, me tu atu ngā paepae whakahoromata pāmahana teitei i roto i ngā taputapu hauora ki te whakahoromata mamaoa pēhanga teitei 121°C, i te wā e tutuki ai ngā kirihou whakarewa phenolic i ngā whakaritenga ātete pāmahana me te akuaku. Me ātete ngā hiri nohoanga takirere ahumahi ki te waikura pāpāho me ngā pāmahana motuhake, e whakaatu ana i tō rātou urutau puta noa i ngā tono rerekē.
