Arotakenga kounga ongā matū whakapūkara phenolic(i hangaia mai i te matū kapia phenolic me ngā whakakī tāpiri, ngā matū whakaora, ngā hinu whakahinuhinu, me ētahi atu, e whakamahia ana mō te hanga pēhi) me kapi ngā āhuatanga matua tae atu ki te āhua, te mahi tukatuka, ngā āhuatanga ā-tinana me te ā-mīhini, ngā āhuatanga wera, me te ātete matū kia tutuki ai ngā whakaritenga hanga me te mahi hua. Ko ngā tūemi me ngā whakaaro motuhake mō te tirotiro koia ēnei:

Tirotiro Āhua Taketake me te Kounga Tirohanga

He tohu mārama te āhua mō te aromatawai kounga tuatahi, e whakaata tika ana i te ōritetanga o te whakaranu rauemi mata me te whakapūtanga (te whakarite paura rānei) i te wā whakaputa. Ko ngā tūemi tirotiro motuhake ko:

Tae me te ōritetanga

Whakaritenga: Me whakaatu ngā hua o roto i te puranga kotahi i te tae ōrite, kāore he rerekētanga tae e kitea ana (ka taea te manatoko mā te whakataurite tirohanga ki ngā tūtohi tae paerewa, mā te ine tau rānei mā te whakamahi i te mita rerekētanga tae).

Hiranga: Tērā pea ka puta te rerekētanga o te tae mai i ngā rerekētanga o te puranga kapia, te horapa koretake o te whakakī, te piki me te heke o te pāmahana tukatuka, ka pā ki te āhua o te hua whakamutunga.

Āhua o te Paura/Granule

Ngā Matūriki: Tirohia mēnā he āhua porotaka, kāore he whakaemi, he pakaru rānei (me ≤ te tere pakaru i te uara kua tohua, ko te tikanga he ≤3%), me te tohatoha rahi matūriki ōrite (ka taea te manatoko mā te tātari tātari paerewa; hei tauira, me tutuki te ōrau 20-60 mata i ngā paerewa a te kamupene).

Paura: Kore he puranga, he mea ke rānei (hei tauira, ngā poke whakarewa, ngā puranga muka). Whakamātauria mā te whakamahi i tētahi mata 100-mata; me ≤0.5% te toenga.

Ngā poke me ngā hapa

Tirohia mā te titiro, mā te karāhe whakanui rānei. Kāore e whakaaetia ngā poke pēnei i te konganuku whakarewa, ngā kōhatu, ngā puranga kapia kāore anō kia marara. Me kore he paru hinu, he ira pokepoke rānei i ngā mata o te kirikiri/paura (hei ārai i ngā mirumiru, i ngā wehewehenga rānei i te wā e whakairohia ana).

Whakamātautau Mahi Tukatuka

Ko te mahi tukatuka o ngā matū whakakikorua phenolic te mea tika hei whakatau i te ngāwari o te whakakikorua pēhanga me te tere o te hua. Ko ngā tūemi whakamātautau matua ko:

1. Te Rerenga (Ngā Āhuatanga Rerenga Rewa)

Tikanga Whakamātautau: Ko te tikanga roa o te rere porowhita (mō ia GB/T 14049-2008)Ngā Matū Whakarewa Phenolic"Werohia te matū whakakoi ki roto i tētahi whakakoi porowhita i te pāmahana kua tohua (hei tauira, 160-180°C) me te pēhanga (hei tauira, 5-10 MPa), kātahi ka ine i te roa o te porowhita i hangaia e te rewa e rere ana.

Paearu Whakatau: Me ≤±10% te rerekētanga o te roa o te rere i roto i te puranga kotahi. Me ōrite ngā uara motuhake ki te hanganga o te hua (me nui te rere o ngā hua angiangi matatini, ko ngā hua matotoru ia me nui te rere o te rere hei ārai i te waipuke).

Hiranga: Ki te kore rawa e rere te wai, ka kore e oti te whakakī, ka puta rānei ngā āputa i ngā kokonga o ngā hua; ki te kore rawa e rere te wai, ka nui haere rānei te waipuke, ka piki ake te utu tukatuka.

2. Tere Whakamaroke (Wā Whakamaroke me te Wā Whakamaroke)

Wā Hāriki: E ine ana i te wā mai i te whakamahana ki te ngaronga o te rere (āhua hāriki) i tētahi pāmahana kua tohua (hei tauira, 175°C) (mō ia GB/T 14049). Ko te tikanga e hiahiatia ana: 50-150 hēkona (ka whakarerekētia i runga i te matotoru o te wāhanga; ko ngā wāhanga matotoru ake me roa ake te wā hāriki hei ārai i te kore e whakamaroke ā-roto).

Wā Whakamaroke: E ine ana i te wā e hiahiatia ana mō te whakamaroke katoa i te pāmahana me te pēhanga kua tohua (ka whakatauhia e ngā huringa pakeke i roto i ngā tauira whakamātautau kua whakarewaina; hei tauira, ko te pakeketanga o Barcol o te 80, neke atu rānei, e tohu ana i te whakamaroke katoa). Ko te tikanga he 3-5 ngā wā o te wā tiēre.

Hiranga: Mā te tere rawa o te whakamaroke ka pā te ahotea o roto me te ngatata o ngā hua; mā te puhoi rawa o te whakamaroke ka roa ake ngā huringa whakaputa me te whakaiti i te whai huatanga.

3. Te Tere Whakaiti (Te Pūmautanga o te Ahu i Muri i te Hanganga)

Tikanga Whakamātautau: Hangaia he tauira paerewa (hei tauira, 120mm × 120mm × 3mm). Kia whakamatao ki te pāmahana rūma, inehia ngā rahi tuturu o te tauira. Whakatauritehia ēnei ki ngā rahi o te pokepoke hei tatau i te tere mimiti (Reiti Mimi = (Ngā Ahu o te Pokepokea – Ngā Ahu o te Tauira) / Ngā Ahu o te Pokepokea × 100%).

Ngā Paearu Whakawa:Pūhui whakapūkara phenolicKo te whakahekenga i te nuinga o te wā kei waenga i te 0.4% ki te 1.2% (he iti iho me ngā whakakī kore-waro, he paku teitei ake me ngā whakakī waro). Me ≤±0.2% te rerekētanga whakahekenga puranga hei ārai i ngā rerekētanga ā-ahu o ngā hua kua oti.
