Hei rauemi whakakotahi,kapia polyester kore-mākūkua whakamahia pai i roto i ngā paninga, i ngā kirihou whakakaha muka karāhe, i te kōhatu horihori, i ngā mahi ā-ringa, me ētahi atu mara. Heoi, ko te kōwhaitanga o te tae o ngā kapia kore-mākū he raruraru tonu mō ngā kaihanga. E ai ki ngā tohunga, ko ngā take noa o te kōwhaitanga o ngā kapia kore-mākū ko ēnei e whai ake nei:
1. I te wā o te tukanga hanga esterification o te kapia kore mākū, nā te mea he nui te pāmahana e puta ai te kōwhai o te kapia kore mākū, ko te pāmahana whānui o te kapia kore mākū he 180 ~ 220 °, neke atu rānei. I tēnei pāmahana, he ngāwari te huri kōwhai o te kapia nā te mea he nui te pāmahana e puta ai, ka pā ki te āhua o ngā hua kapia.
2. Ko te kōwhai i puta mai i te pānga o te kapia ki ngā hihi ultraviolet, ko te nuinga o te wā, nā te noho mai o ngā mowhiti benzene i roto i te kapia (tae atu ki ngā waikawa dibasic kakara/anhydrides me ngā mowhiti benzene i whakaurua mai e te styrene), tērā pea nā te waikura wera o ngā matū kakara i ngā pāmahana teitei. Ka ngāwari te pirau ki ngā whakawhiti hiko, ka kōwhai te kapia.
3. I roto i te tukanga hanga kapia, ka pāngia ngā rauemi mata e te hāora nā te ngoikore o te mahi hiri o te taputapu. Ko te mekameka ngota o te polyester kore-mākū whānui ehara i te mea ko ngā rōpū ester, ngā rōpū meridian, me ngā rōpū antelope anake, engari ko ngā hononga takirua me ngā mowhiti kakara. Ka pāngia e te waikura wera, ā, ko te mahi kitea ko te huri o te tae o te kapia ki te kōwhai.
4. Te awe o ngā tāpiringa pēnei i ngā antioxidants, ngā aukati polymerization, ngā kaihoko whakaora, me ētahi atu. Ka ngāwari te huri i ngā antioxidants amine hei rauropi kore utu nitroxide hei tae i te hua. Ko ngā aukati polymerization e whakamahia whānuitia ana, pēnei i te hydroquinone, ko te whakahāngaitanga ki ngā quinones i te aroaro o ngā quinones, he tae anō hoki ō rātou, ā, ka pā ki te tae o te kapia. Kei te whakamahi tonu ētahi kaihanga o ngā kaihoko whakaora i ngā pūnaha acyl peroxide-tertiary amine me ngā pūnaha hopi whakarewa ketone peroxide. He kapia tae, he ngāwari ki te tae.
Heoi anō, tera atu anō ngā take e huri ai te kapia ki te kōwhai. Ko te tikanga whānui, ko te hāora wera me ngā hihi ultraviolet ngā tino take o te kōwhai. Ka whakamahia te waikawa dibasic kukū (te waikawa anhydride rānei) hei whakakapi mō te waikawa dibasic kakara (te waikawa anhydride rānei), ahakoa ka taea te whakamahi ki tētahi taumata, ka taea te whakamārama ake i te tae o te kapia, engari i runga i ngā āhuatanga maha pēnei i te mahi me te utu o te kapia, kāore tēnei tikanga i te pai.
E ai ki ngā tohunga, hei tāpiri atu ki te whakakī i te hau kore mahi i roto i te tukanga whakaputa me te rokiroki hei ārai i te pa atu ki te hāora i te nuinga o te wā, ko tētahi tikanga whai hua ake ko te tāpiri i ngā antioxidants me ngā absorbers ultraviolet, ka taea te ārai i te kōwhai o te polyester kua puhoi. Ko ngā otinga ārai-kōwhai e taunakihia ana e ngā tohunga mō ngā kapia kore-mākū ko:
Ka tīpakohia ngā antioxidants kāore he amines, ā, ka whakamahia ngātahitia ngā antioxidants tuatahi me ngā antioxidants āwhina. Ko ngā antioxidants tuatahi ko ngā phenols ārai, ka taea te hopu i ngā rauropi kore utu peroxide; ko ngā antioxidants āwhina ko ngā phosphites, e pirau ana i te hydroperoxide, ka taea hoki te whakakōpiko i ngā ion whakarewa hei ārai i te tae waikura o te kapia. Mena kei te hiahia koe ki te whakapai ake i te ātete ki te kōwhai me te ātete ki te huarere, me tāpiri he ngongo UV. Mā te tāpiri i te ngongo UV ka taea te aukati i te āhua kōwhai o ngā rauemi polymer i raro i te mahi a ngā hihi ultraviolet, ā, ka whakarato i te tiaki pai ki te hua, ka ārai pai i te whakaiti i te kanapa, te hanga kapiti, ngā mirumiru, me te wehewehe ka taea te whakapai ake i te ātete huarere o te hua, ā, he pai te pānga tahi ina whakamahia tahi me ngā antioxidants. Ko te tikanga, kāore e taea e te whakamahinga o ngā antioxidants me ngā ngongo UV te whakaoti rapanga o te kōwhai, engari i roto i tētahi whānuitanga, ka taea tonu te ārai i te kōwhai waikura o ngā hua polyester kore-mākū, te pupuri i te wai o te hua kia mārama, me te whakapai ake i te kounga o te hua.
