Thermoplastic vs Thermoset

Thermoplastic vs Thermoset

Ko te Thermoplastic e tohu ana ki te taonga ka rere me te rerekee te matū ina whakamahana, ka mau tonu te ahua i muri i te whakamahana. Ko te nuinga o nga polymers raina e whakaatu ana i te thermoplasticity me te ngawari ki te tukatuka ma te tangohanga, werohia, pupuhi pupuhi ranei. Ko te Thermosetting e tohu ana ki te taonga e kore e taea te whakangwari me te hanga repeka whakamahana, kaore e taea te rewa ki te whakarewa. Ko nga polymers nui kei tenei taonga.

He huringa matū te whakamaarama. Whai muri i te whakamahana, kua huri te hanga, kua huri hei matū kē. Hei tauira, kaore e taea e koe te whakahoki mai i te hua i muri i te maoa. Ko te Thermoplasticity he huringa tinana. Ko te mea noa ka huri te ahua o te taonga i te wa e wera ana, engari kaore te hanganga e rereke. He tangata whenua tonu. Hei tauira, ka rewa te rama i te wera, ka taea te whakahoki ki te rama taketake, engari ko te wera o te rama he huringa matū.

1. Thermoplastics

Ka ngohe, ka rere ina wera, ka whakapakeke ina whakamatao. Ko tenei tukanga ka taea te huri, ka taea te repekai. polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyoxymethylene, polycarbonate, polyamide, acrylic plastic, other polyolefins and their copolymers, polysulfide, polyphenylene ether, chlorinated polyether, etc. He thermoplastic. Ko nga mekameka rāpoi kapia i roto i te thermoplastics he raina katoa, he peka ranei. Karekau he here matū i waenga i nga mekameka ngota, ka ngohe, ka rere ina wera. Ko te tukanga o te whakamatao me te whakapakeke he huringa tinana.

2. Hangaia nga kirihou

Ka whakamahana mo te wa tuatahi, ka ngawari, ka rere. Ka whakawerahia ki tetahi pāmahana, ka puta he tauhohenga matū ki te hono-whakawhiti, ka pakari kia whakapakeke. Ko tenei huringa kaore e taea te huri. I muri i tera, ka wera ano, kaore e taea te ngohe ka rere. Na tenei ahuatanga ka mahia te mahi hangai, ka whakamahia te rere kirihou i te wa o te whakamahana tuatahi hei whakaki i te kohao i raro i te pehanga, katahi ka whakakoi ki te hua o te ahua me te rahi. Ka kiia tenei rauemi he thermoset.

Ko te kapia o nga kirihou thermosetting he raina, he peka ranei i mua i te rongoa. Whai muri i te rongoa, ka hangaia nga here matū i waenga i nga mekameka ngota hei hanga i te hanganga whatunga ahu-toru. Ehara i te mea kaore e taea te rewa ano, engari kaore e taea te rewa i roto i nga whakarewa. Phenolic, aldehyde, melamine formaldehyde, epoxy, polyester unsaturated, silicone me etahi atu kirihou he kirihou whakamatao katoa.
