PTFEe wātea ana i roto i te maha o nga Tohu rite Virgin PTFE, PTFE kua whakarereketia, Carbon Filled PTFE, Glass Filed PTFE, Carbon / Coke Filled PTFE, Graphite Filled PTFE, Bronze Filled PTFE, Bronze + Molybdenum Disulphide Filled PTFE, Aluminium Oxide Filled PTFE, Calcium Fluoride PTFE whakakiia, PTFE Kowiri tira whakakiia, PTFE whakakii Mica, Karaehe + MoS2 PTFE whakakiia, PTFE whakakii moS2, PTFE kua whakarerekehia matū etc.
Ko te whakapiri i waenga i nga papa reti e rua, na te waku e kore e taea te hanga i roto i te rohe whakapiri, ka puta he kakahu e whakawhirinaki ana te nui ki te kawenga, te tere me te wa o te paheketanga.Ko te tikanga, i waenganui i enei tawhā me te kakahu ka puta he hononga e rite ana ki:
R = KPVT
i roto i nga waeine ine o te ripanga:R = mau i roto i te mmP = uta motuhake i roto i te N/mm2 (e tohu ana ki te mata – Ø xl – ina he ngahere, nipples, etc.)V = tere retireti i roto i te m/secT = Wā i roto i te hāoraK = tauwehe mau i roto i te mm3 hēkona/Nmh.
Ko te uara o te tauwehe PV i muri mai ka ngaro te ahua o te whakarea o te kakahu, ki te whakaaro ko nga uara whakamiharo me te punaha mai i te ngoikore ki te ahua kakahu kaha, ka kiia ko "tepe PV".Ko tenei tepe PV me te take kakahu, na reira, he tawhā ahuatanga o ia rawa.I roto i te mahi, Heoi, ka taea te mohio ngawari, ko te take kakahu me te rohe PV o taua mea whakakiia ka rereke ano ki te ahua, te pakeke me te mutunga o te mata o tetahi atu "hoa" whakapā me te aroaro, kaore ranei, o nga wai whakamatao, whakahinuhinu hoki/ranei.
Deformation i raro i te kawenga me te kaha compressive PTFE, rite te nuinga atu rauemi kirihou, kahore "rohe rapa" i reira te kawenga ōwehenga / deformation (Young modulus) he uara tonu.Ko tenei taumahatanga o te taumahatanga/whakarereketanga ka whakawhirinaki ki te wa o te tono o te utaina me nga huringa ka whai ake;Ko tenei ahuatanga e mohiotia ana ko te "ngoki", a, i te tangohanga o te kawenga, he waahanga noa iho te hokinga mai o te huringa ki te ahua taketake ("whakaora elastic"), kia noho tonu ai tatou i te aroaro o te "whakarereketanga pumau. ”.
Ko te ngokingoki, karekau i te mahi ahorangi o te wa, ka puta i muri noa iho i te 24 haora i te ahua o te ahua o te ahua kaore i te whakaarohia.Na te piki haere o te pāmahana, ka heke te ahua o te ahua i raro i nga ahuatanga o te utaina, na reira ko te kaha o te kaha o te kopiri kei te 100°C rite ki te 1/2 o tera i te 23°C me te 200°C mo te 1/10th.
I roto i tetahi take, PTFE me i roto i ngāPTFE whakakiia, Ko tetahi o nga mea kirihou e pupuri ana, i nga wera teitei, nga ahuatanga rerekee tino pai i raro i te kawenga.Hei whakatau, ko te whakaora elastic i roto i te 50% o te deformations i raro i te kawenga, me te deformations pūmau he rite ki te 50% o te deformations i raro i te kawenga.
E pa ana tenei ki nga PTFE kua whakakiia me te kore whakaki.Ko nga taonga o te tuatahi he tino pai ake.Ko te mea pono, ko te whakarereketanga i raro i te kawenga o nga momo noa ake o te PTFE kua whakakiia e pa ana ki te 1/4 o nga mea kaore i whakakiia, ko te kaha o te kaha o te pupuhi e pa ana ki te rua.
Nga Taonga Ngawha o te PTFE kua whakakiia
Ko te roha waiariki o te PTFE kua whakakiia he iti ake i tera o te PTFE kaore i whakakiia, ka nui ake i te ahunga o te hangai i te whakawhiti.He pai ake te kawe i te waiariki ki tera o te PTFE kaore i whakakiia, ina koa ka whakamahi i nga whakakii e mau ana i a raatau ake te kawe waiariki.
Ko te PTFE kua whakakiia he pai ake nga waahanga waiariki i nga mea kaore i whakakiia.
Nga Taonga Hiko o te PTFE kua whakakiia
Ko enei ahuatanga ka whakawhirinaki ki te ahua o te whakakii.Ko te PTFE anake e whakakiia ana ki te muka karaihe ka mau i nga taonga dielectric pai, ahakoa he rereke ki era o te PTFE kaore ano kia whakakiia.Hei tauira, he rereke te nui o te rōrahi me te parenga o te mata, te taurua dielectric me te tauwehe tohanga i te rereketanga o te makuku me te auau.
