I roto i te hoahoa tiaki wera o ngā hua rererangi, mō ngā wāhanga e hiahia ana ki te matotoru nui, he āhua uaua, he ngāwari rānei ki te pakaru i te ahotea, he maha ngā wā ka whakamahia ngā rauemi hiato hei whakakapi mō ngā paninga tiaki wera tuku iho. Hei tāpiri, he maha ngā kōwhiringa hanga a ngā hanganga tiaki wera hiato: ka taea te hanga tere tika ki te wāhi tiaki wera motuhake, ka taea rānei te here ki te wāhi tika mā te whakamahi i ngā ringaringa tiaki wera hiato kua oti te hanga, ā, ka tukuna he painga motuhake o te tukanga whakarite whai hua me te watea. I tēnei wā, he whānui te whakamahinga o ngā hiato muka karāhe phenolic i roto i ngā hanganga tiaki wera nā ō rātou painga maha, tae atu ki te pumau o te hanganga, te ātete pāmahana teitei, te nui o te hua waro, te iti o te tere tango, te kaha miihini teitei, me te pakari pānga pai.

Ngā hiato muka karāhe phenolicHe nui te kaha o tēnei rauemi hei whakamahi whānuitia i roto i te rāngai rererangi. Ko tā rātou tikanga tiaki wera he mahi tahi a ngā tukanga tiaki maha, tae atu ki te aukati i te kawe wera, te whakawera wera i roto i te wera, te whakamarumaru wera e whakaratohia ana e te paparanga waro, me te tautoko hanganga. Ka tātarihia e tēnei pepa te tikanga tiaki wera mai i ngā tirohanga o te aukati kawe wera, te whakawera wera i roto i te wera, me te whakamarumaru wera e whakaratohia ana e te paparanga waro.

1. Te aukati i te kawe wera

I roto i ngā rauemi muka karāhe phenolic, he iti te kawe wera o te matūriki kapia phenolic, e whakaroa ana i te kawe wera o waho. Ina tukuna te rauemi rauemi ki ngā taiao pāmahana teitei i te wā e rere ana, ka horapa te wera ki roto mai i te mata o waho. Heoi, ko te hanganga mekameka macromolecular o te matūriki kapia phenolic ka aukati i ngā ara kawe wera, ā, ka heke te tere o te whakawhiti wera. I te wā kotahi, ko te noho mai o ngā muka karāhe i roto i te rauemi rauemi ka whakarerekē anō i ngā ara kawe wera o roto. Heoi anō, ko te hononga i waenga i ngā muka karāhe me te kapia phenolic he ātete wera teitei; nō reira, ka tūtaki te wera ki te aukati tāpiri i a ia e whakawhiti ana i tēnei hononga, ka aukati anō i te tukanga kawe wera, ā, ka whakaheke pai i te tere o te pikinga pāmahana i roto i te rauemi rauemi rauemi.

2. Te Whakapūngao Iti-Pawera

Ina pāngia e ngā taiao o waho e te pāmahana teitei, ka pāngia tonutia te kapia phenolic e ngā tauhohenga pyrolysis. He tauhohenga endothermic tēnei tukanga pyrolysis: i te mimiti i te kaha wera, ka pakaru ngā hononga matū i roto i ngā ngota kapia phenolic, ka pirau te rauemi hei hau ngota iti me ngā toenga waro. Ka pau pai i tēnei tukanga te kaha wera i whakawhitia mai i te taiao o waho ki te mata o te rauemi hiato, ā, i te wā kotahi ka whakaheke i te pāmahana o te mata o te rauemi hiato. 3. Te Ārai Wera mā te Papa Waro

I te haere tonu o te tauhohenga pyrolysis, ka āta hangaia he paparanga waro ki runga i te mata o tete whakakotahitanga kapia phenolic. He hanganga pūwero tēnei paparanga waro, ā, kī tonu ōna pūwero i ngā hau e whakaatu ana i te kawe wera tino iti; ka whakarei ake tēnei āhuatanga i ngā kaha whakamahana o te rauemi hangai. I te wā kotahi, he kakano mata mārō te paparanga waro e kaha ana ki te tu atu i ngā pēhanga hau me ngā kawenga miihini, ā, ka tiaki i te rauemi kāore i wera i raro mai i ngā pānga horoi me te horo o ngā rere hau pāmahana teitei. Ehara i te mea he mahi whakamahana anake te paparanga waro i hangaia i runga i te mata hangai, engari, ki tētahi taumata, ka whakaiti i te ngaronga papatipu i roto i te rauemi hangai, ā, ka roa ake te ora o te hanganga tiaki wera.
