Te Kōwhiringa Peera Mama me te Whai Hua: He Tātaritanga Whānui o ngā Rauemi Kete Kirihou Hangarau

 

I roto i te hurihuri houte whārikiI te hoahoa, he wāhanga matua te whare herehere, ā, ko te whiriwhiri rauemi ka pā tika ki te mahi a te peera, te roa o te ora, me ngā tono e tika ana. Ki te whakatauritea ki ngā rauemi whakarewa tuku iho, kei te piki haere te rongonui o ngā whare herehere kirihou hangarau i roto i ngā momo ahumahi nā ō rātou āhuatanga ā-tinana me te matū ahurei.

 

Ka arotahi tēnei tuhinga ki ngā kirihou hangarau matua pērā inairona (PA), polioksimetirene (POM), me te porimiti (PI), te tātari hōhonu i ō rātou painga mahi me ngā rohe e tika ana mō ngā tono whare herehere.

 

Whakataurite Mahi Rauemi Matua

 

Nairona (PA)

 

Nā tōna pakari, tōna whakahinuhinu-ā-roto, me ōna painga utu, he whānuitia te whakamahinga o te nairona i roto i ngā peera e mahi ana i raro i ngā kawenga reo me ngā pāmahana reo. Ko tōna tauwehenga waku iti ka āwhina i te whakaiti i te haruru mahi, ka tino pai mō ngā taputapu whare me ngā taputapu tari e hiahia ana ki ngā taumata tiketike o te ata noho. E ai ki te Rolling Bearing Application Handbook, he pāmahana mahi tonu a PA66 tae atu ki te 120°C, ā, ka taea te tu atu i ngā pāmahana poto tae atu ki te 150°C. Ko tōna uara PV (pēhanga × tere) he tata ki te 50 MPa·m/s, ka pai mō te mahi tere reo.

 

Polyoxymethylene (POM)

 

E mōhiotia ana te POM mō tōna pakari teitei, tōna iti o te ngoki, me tōna pumau āhua pai rawa atu. Nā tōna mata maeneene me tōna ātete pai ki te kakahu nairona, he pai mō ngā whare pupuri i roto i ngā tono taputapu tere-nui, kawenga māmā, tika rānei. Ko te awhe pāmahana whakahaere o te POM he -40°C ki te 100°C, me te mahi poto tae atu ki te 120°C. Ka taea e tōna uara PV te eke ki te 60 MPa·m/s, he mea pai mō ngā motuka tere-nui me ngā pūnaha horoi motuka.

 

Polyimide (PI)

 

Hei tohu mō ngā kirihou hangarau mahi-teitei, he tino pai te ātete pāmahana teitei a te PI (tae atu ki te 260°C mō te whakamahinga roa) me te pupuri tonu i te kaha miihini me te ātete irahiko. Ka taea e tōna uara PV te neke atu i te 100 MPa·m/s, e pai ai mō ngā taiao tino kino pēnei i te rererangi, ngā motuka pāmahana-teitei, me ngā pūnaha peera i roto i ngā taputapu korehau. Ahakoa te utu nui ake, kāore e taea te whakakapi i roto i ngā āhuatanga whakahaere motuhake.

 

Ngā Painga Whānui o te Hangarau i ngā Kete Kirihou

 

Māmā: Nā te mea he kotahi-whitu noa iho tōna mātotoru i te maitai, ka whakaitihia e te kirihou te taumaha katoa o te pikaunga, ka whakaitihia te ātete, ā, ka whakapai ake i te urupare hihiri.

 

Mahi Haruru-Iti: He iti te modulus pīngore o ngā kirihou, ā, ka mimiti pai i ngā wiri mō te mahi mārire.

 

Ngā Āhuatanga Whakahinuhinu-ā-roto: Ko te nuinga o ngā kirihou hangarau ka whakahinuhinuhia ki roto, ka whakaiti i te whakawhirinaki ki te whakahinuhinu o waho, ka roa ake hoki ngā wā tiaki.

 

Ātete ki te Waikura: He ātete ki te wai, ki te hinu, me ngā momo matū rerekē, he pai mō te whakamahi i roto i ngā taiao makuku, waikura rānei.

 

Ngā Taunakitanga me ngā Paerewa Kōwhiringa

 

E ai ki te paerewa JB/T 7048, me whai whakaaro whānui ki te kawenga, te tere, te pāmahana, me ngā āhuatanga taiao i te kōwhiringa o ngā kēke kirihou. He pai ake te POM mō ngā tono tere-tiketike, iti-haruru; he kōwhiringa te PA mō ngā āhuatanga mahi taurite; ā, e taunakihia ana te PI mō ngā pāmahana tino tiketike, ngā whakaritenga pono teitei rānei.

 

Ehara i te mea he whakakapinga noa iho ngā whare kirihou hangarau mō te konganuku; engari, kua arotauhia kia pai ai te mahi i roto i ngā tono motuhake. Mā te whiriwhiri rauemi pūtaiao, ka taea te whakapai ake i te whai huatanga, te marino, me te roa o te ora, me te pupuri tonu i te pono o te peera. Mā te whanaketanga o te hangarau rauemi, ka whānui haere tonu ngā rohe tono o ngā kirihou mahi-teitei i roto i ngā peera.
