I te tere o te whanaketanga o ngā kirihou whakakaha muka karāhe hangarau,ngā rauemi e hangai ana ki te kapia phenolickua whānuitia te whakamahinga puta noa i ngā momo ahumahi. Nā te kounga ahurei, te kaha miihini teitei, me te mahi tino pai tēnei. Ko tētahi o ngā rauemi tino nui korauemi kapia muka karāhe phenolic.
muka karāhe phenolic, i roto i ngā kapia hangai ahumahi tuatahi, he polycondensate i hangaia e te polymerization o ngā phenols me ngā aldehydes i te aroaro o te whakakorikori kawakore. Kātahi ka whakaurua ētahi tāpiri hei whakawhiti i te hanganga macromolecular, ka hurihia hei hanganga macromolecular toru-ahu kore e rewa me te whakauru, ā, ka noho hei mea noa.rauemi pūmua whakaweraHe tino taonga ngā kapia phenolic mō ō rātou āhuatanga tino pai, tae atu ki te ātete mura pai, te pumau āhua, me te kaha miihini pai. Nā ēnei āhuatanga i akiaki te rangahau whānui me te whakamahinga o ngā rauemi kapia muka karāhe phenolic.
I te tere haere o te whanaketanga o ngā ōhanga ahumahi, ka piki haere ngā tono mō te mahi a ngā rauemi muka karāhe phenolic. Nō reira,muka karāhe phenolic whakarerekētia, he kaha teitei, he ātete wera hokikei te whakawhanakehia whānuitia, kei te whakamahia whānuitia hoki.Kapia phenolic whakarerekē kua whakakahangia ki te muka karāhe (FX-501)Ko tētahi o ngā rauemi kapia muka karāhe phenolic kua whakarerekētia te angitu i tēnei wā. He momo rauemi phenolic hou kua whakarerekētia, kua whakapakaritia hoki, i hangaia mā te whakauru i ngā muka karāhe ki roto i te hanganga kapia taketake mā te whakaranu.
Ngā Āhuatanga Ā-Mīhini me ngā Tūranga Ā-Wāhanga
Kapia muka karāhe phenoliche maha ngā wā ka whiriwhiria hei matihiko mōngā rauemi ātete ki te kakahu, ki te kume, me te pēhanganā tōna kaha kume pai, tōna ātete whakarewa, me ōna āhuatanga miihini pai rawa atu pērā i te ātete mura.rauemi matihikohe mea hono te mahi matua, arā, he mea honohono i ngā wāhanga katoa.muka karāhehei waeine kawe kawenga matua i roto i ngā rauemi ātete-kakahu, e whakarato ana i te kaha kawe kawenga, ā, ko tō rātou mahi pai rawa atu ka pā tika ki te pānga whakapakari i runga i te matihiko.
Ko te mahi a te rauemi matihiko he hono pūmau i ētahi atu wāhanga o te rauemi kume, kia rite ai te whakawhiti, te tohatoha, me te tohatoha i ngā kawenga ki ngā momo muka karāhe. Mā tēnei ka puta he kaha me te pakari ki te rauemi. Ko ngā muka noa, tae atu ki ngā muka karāhe, ngā muka rauropi, ngā muka maitai, me ngā muka kohuke, ka whai wāhi ki te whakatikatika i te kaha kume o te rauemi.
Te Whakapūmau Utaina i roto i ngā Hiko me te Pānga o te Ihirangi Muka
In rauemi hiato muka karāhe phenolicngā pūnaha, ngā mea e ruaka pikau te muka me te kapia matrix i te kawenga, ko ngā muka karāhe tonu te kawenga matua. Ina pāngia ngā muka karāhe phenolic e te ahotea piko, te ahotea pēhanga rānei, ka whakawhitia te ahotea mai i te kapia matrix ki ngā muka karāhe takitahi mā roto i te atanga, ka horapa pai te kaha i mau. Ka whakapai ake tēnei tukanga i ngā āhuatanga hangarau o te rauemi hiato. Nō reira, he pikinga tika oKa taea e te ihirangi muka karāhe te whakarei ake i te kaha o ngā hiato muka karāhe phenolic.
Ko ngā hua o te whakamātautau e whakaatu ana i ēnei e whai ake nei:
- Ngā hiato muka karāhe phenolic me te 20% o te ihirangi muka karāhekāore i te ōrite te tohatoha muka, ā, i ētahi wāhi kāore he muka.
- Ngā hiato muka karāhe phenolic me te 50% o te ihirangi muka karāhee whakaatu ana i te tohatoha muka ōrite, ngā mata whati koretake, ā, kāore he tohu nui o te kukume muka whānui. E whakaatu ana tēnei ka taea e ngā muka karāhe te pikau ngātahi i te kawenga, ka hua akekaha piko teitei ake.
- Ina 70% te nui o te muka karāhe, ko te nui rawa o te muka ka hua ake he iti noa te ihirangi kapia matrix. Ka taea e tēnei te whakaputa i ngā āhuatanga "kore kapia" i ētahi wāhi, ka aukati i te whakawhiti ahotea me te hanga i ngā kukū ahotea ā-rohe. Nō reira, ko ngā āhuatanga hangarau whānui o te rauemi hiato muka karāhe phenolicka heke iho.
Mai i ēnei kitenga, ko teKo te tāpiritanga mōrahi o te muka karāhe e whakaaetia ana ki ngā hiato muka karāhe phenolic he 50%.
Te Whakapai Ake i te Mahi me ngā Take Whakaawe
Mai i ngā raraunga tau,ngā hiato muka karāhe phenolickei roto ko te 50% muka karāhewhakaatu tata kie toru ngā wā o te kaha pikomee whā ngā wā o te kaha pēhiki te whakataurite ki te kapia phenolic parakore. Hei tāpiri, ko ētahi atu mea e pā ana ki te kaha o ngā kirihou whakakaha muka karāhe phenolic ko tete roa o ngā muka karāheme ā rātoute aronga.
