Epoxy kapia: he taputapu mahuinga i roto i ngä rängai katoa

Epoxy Resin - taonga he ātete nui ki te waikawa, turanga me kōnakonako. Ko te oligomer waihanga. Ka taea te whakamahi i te reira ki te amuiraa tata tetahi rauemi. I roto i te āhua wai ko te kapia epoxy mārama, e kua he tae kōwhai-karaka, a i muri i whakapakeke riro te reira parauri, me te ngā haumaru mō te hauora. Heoi, tona whakamahi wahi i reira kia kia whakapā pea ki whakarewa, hautanga Sol-leachable taea. I roto i te āhua wai ko reira rawa paitini, na titau tona whakamahi pipiki ki te huinga o ngā ture.

O te akoranga, mō te honohono i te rihi atu tūemi ranei e tae mai ki te whakapā ki te kai ranei te wai inu, e taea e kore te whakamahi i te reira mo tenei whakaaro i reira e te tahi atu matū. Heoi, e tika ana ki o ratou āhuatanga, te kāpia epoxy ko te taputapu mahuinga ia i roto i te whānuitanga rawa whanui o ahumahi. E rua ngā whakamahinga matua o te rauemi: hei piripiri me impregnation. Ki te tona awhina tiaki ki te waikura o te raima, whakarewa, pakete hanga, kāpia momo, ara he wahi tino nui i roto i tata manga katoa o engineering. Epoxy kapia me kaka kōata e tīmata rauemi mo te hanga o te muka karaihe, Kei te whānui i whakamahia i roto i te paturaa, boat- me te ahumahi rangi. Ano, whakamahia te tuatahi te ki te whakaki i roto i te hikohiko, me te ara i roto i te hoahoa.

whakamahia epoxy kapia e i roto i te taupiri ki te hardener. Kei hea he Kāore i roto i te taiao ā-whare te maimoatanga wera, kei te whakamahia ratou i roto i ngā awheawhe iti taonga matao. A mo hua nui, hangaia ki te mahi i te pikaunga pateko, me te hihiri tiketike i roto i ngā taiao ha'iriiri - wera te whakaora i āpiha. I roto i tenei take, he mātiti apiapi whakamau rāpoi polymer. I tua atu, i reira e he teriuma epoxy me hardeners, hangaia mō te tikanga o te haumākū nui, te wai tote.

Mahi ki tona ora, kia mohio ki taua mea e hangaia te pūhui, me tona hardener te tauhohenga putawera, me te nui te taimaha o te waerau, te nui te wera. I roto i tenei hononga ko reira e tika ana ki te whiriwhiri i te maha e tika ana o āpiha, a kia correlate reira ki te whakaaro o te whakamahi, rite ki te hua, kia whiwhi i te kākahu (kahore mirumiru) totoka. I tua atu, he tina heke te tauhohenga o te teriuma me te hardener, a muri thermoset, e kore e taea e rewarau pērā ngohe ranei tareka ki te rework hua. E whakaaro ana te rauemi tino noa, me te utu mo te oreraa o te rauemi epoxy inaianei Paper, DETA, TETA, TEPA ko №1 (hexamethylene tiamine rewa i roto i te Ethyl waipiro). Nā ki te meka e tikanga pūhui e rua-wae - he mea pai he pakarukaru, nui haere tona elasticity e mā te tāpiri i tētahi atu wae. huaina ana tēnei huānga ko "pūwhakakē pānga", kia whai i te reira i te hanganga matū rerekē, me te, i runga i tenei kei, i etahi āhuatanga. Kua kitea Utaina pono rauemi e whai i te kaha ki te mahi e rua rite te hardener, me he pūwhakakē pānga.
