Me pēhea te whakapakari ake i te ātete ki te rakuraku me te ātete ki te kakahu kirihou

Kōwhiria te kapia taketake tika

Ko te polyethylene taumaha ngota tino teitei (PE-UHWM) tētahi o ngā kirihou tino ātete ki te kakahu, ā, mā te whiriwhiri i te PE-U·HWM ka taea te whakapai ake i te ātete kakahu o te rauemi. Hei tāpiri, ko te kirihou he nui te tioata, he nui te auau, he ātete kakahu ake i tērā he nui te pakeke. I roto i te whakarerekētanga polypropylene (PP), #mīhini whakapūkara pp Ko te elastomer polyolefin (POE), te rapa ethylene propylene terene (EPDM), te rapa whakamomona hihiri thermoplastic (TPV) (pērā i te PP/EPDM whakamomona hihiri) e whakamahia ana hei whakapakari i te PP, ā, ko te tāpiri i ngā elastomer ka heke te ātete ki te rakuraku, nō reira he mea tino nui te whiriwhiri i te elastomer tika. Ko te raupapa o te ātete ki te rakuraku penei: TPV > EPDM > POE. #mīhini hanga paura pp.

Whakamahia he whakakī ātete pai ki te kakahu

(1) Molibdenum disulfide

Ko te molybdenum disulfide, he tāpiringa ātete-kakahu, e whakamahia nuitia ana i roto i ngā kirihou nairona. Ka mahi te molybdenum disulfide hei kaihoko whakatio hei whakanui ake i te whakatio o te nairona, kia mārō ake ai te mata o te rauemi nairona, kia ātete hoki ki te kakahu. He nui te kaha o te molybdenum disulfide ki te konganuku, ā, ina piri ki te mata konganuku, ka whakakīia e ngā ngota molybdenum disulfide te mata konganuku ki ngā pūwero iti rawa, ā, ka maeneene ake te mata konganuku, ā, ka pai te molybdenum disulfide hei tāpiringa ātete-kakahu mō ngā wā waku nairona me te konganuku.

(2) Karāpiti

Ko te hanganga o te karāpeti he hanganga karaihe o te karāpeti kohuke, he paparanga hexagonal, nā tēnei hanganga matū ahurei ka ngawari te paheke o ngā ngota karāpeti tetahi ki tetahi ina iti te waku, he mea tino nui tēnei ātete kakahu i roto i te taiao wai, nō reira ko te karāpeti hei tāpiri ātete kakahu pai rawa atu ka whakamahia i roto i te maha o ngā wāhanga kua whakanohoia ki roto i te wai, pērā i te anga wai, te mata me te hiri. #mīhini papa tauira hanga pp #mīhini hanga pepa pahuka xpe

(3) Karāhe muka

Ka taea e te muka karāhe te hanga hononga ā-pūkaha i waenga i ngā pūmua, nō reira ka taea e te muka karāhe te whakapai ake i te pumau o ngā hanganga kirihou wera me te ātete ki te kakahu. Ka whakakaha te muka karāhe, ā, ka taea te whakapai ake i te kawe wera me te whakarerekētanga wera o ngā kirihou, ka tino whakapai ake i te ātete ki te kawenga me te ātete ki te kakahu o ngā kirihou.

(4) muka waro

#Mīhini Whakakotahi CFRTP

Pērā i te muka karāhe, ka taea e te muka waro te whakapai ake i te hanganga o te rauemi, te ātete ki te kawenga me te ātete ki te kakahu. Kāore i rite ki te muka karāhe, he ngawari ake te muka waro, ā, kāore e rakuraku, ā, e kore te muka waro e rakuraku i te mata waku o te rino, te maitai rānei e mirimirihia ana.

Tāpirihia ngā tāpiringa ātete-kākahu e tika ana

(1) Polytetrafluoroethylene (PTFE)

He tino iti te tauwehenga waku o te Polytetrafluoroethylene (PTFE), ā, ka hangaia e ngā ngota PTFE he kiriata whakahinuhinu i runga i te mata o te wāhanga i te wā waku. He pai te whakahinuhinu o te PTFE me te ātete ki te kakahu i raro i te waku, ā, koia te tāpiri pai rawa atu e ātete ana ki te kakahu i roto i ngā tono kawenga teitei. Kei roto i ēnei tono kawenga teitei ko ngā hiri mowhiti piston waipēhi me ngā horoi pana. Ko te ihirangi PTFE i roto i ngā kirihou kore-ahua he 15% te tikanga, ā, i roto i ngā kirihou tioata he 20%.
