Ina kore e pai ngā whitiki paerewa, ka tino pai a Kevlar

I roto i ngā taiao ahumahi pāmahana teitei—te hanga karāhe, te tukatuka maitai, me ngā raina maimoatanga wera—ka tere te pirau o ngā whitiki kawe paerewa i raro i te ahotea wera, ka nui te utu mō te kore mahi me te whakakapinga pinepine. Mō ngā kaiwhakahaere tipu, ngā miihini hoko, me ngā kaiwhakauru taputapu e pāngia ana e ngā wero wera nui, he mea nui te pātai: He aha te whitiki kawe Kevlar pāmahana teitei, ā, he aha i pai ake ai i ngā kōwhiringa tuku iho?

Ko te whitiki kawe Kevlar pāmahana teitei he otinga whitiki ahumahi i hangaia ki te muka aramid DuPont™ Kevlar®—he ranunga rānei o Kevlar me ngā muka maitai kore waikura me te PBO—i hangaia hei tu atu i ngā pāmahana mahi tonu mai i te 260°C tae atu ki ngā tihi tere o te 550°C me te pupuri tonu i te kaha kume me te pumau o ngā āhuatanga. He rerekē ki ngā whitiki taura polyester/nylon (EP) me ngā whitiki taura maitai e totoro ana, e heke ana, e ngaro ana rānei te āhua i raro i te wera, ka roa te ora o ngā whitiki Kevlar i roto i ngā taiao wera tino uaua.

He aha ngā mea e hanga anaNgā Whitiki Kawe KevlarĀtete ki te pāmahana teitei?

Te Painga o Kevlar

He muka aramid kaha-teitei, māmā hoki a Kevlar i whakawhanakehia e DuPont, e tuku ana i:

• Ātete wera tino pai: Mahi tonu tae atu ki te 260°C; ka eke ngā tihi tere ki te 550°C
• Kaha kume teitei: Ka taea te whakahaere i ngā kawenga taumaha me te kore e totoro, e whati rānei
• Te roa iti: I raro iho i te 0.5%, e whakarite ana i te pumau o te taha i raro i te kawenga
• Māmā: Tae atu ki te 30% te māmā ake i ngā whitiki taura waea maitai he rite te kaha, ka whakaiti i te whakapaunga pūngao
• Ātete matū me te ātete waikura: Kāore e pāngia e te mamaoa wai, e ngā kohuke waikura, me te nuinga o ngā matū

Ngā Ranunga Whakakotahi mō te Mahi Whakapai Ake

He maha ngā whitiki kawe Kevlar pāmahana teitei e whakauru ana i ngā rauemi tāpiri hei arotau i ngā āhuatanga motuhake:

Ngā Momo Whitiki Kawe Kevlar Pāmahana Teitei

1. Whitiki Kevlar Whatu Papatahi

I hangaia mā te whakamahi i ngā tikanga whatu matotoru, maha-paparanga. Ko te matotoru noa mai i te 0.7mm ki te 6mm, me te whānui tae atu ki te 500mm, neke atu rānei. He pakari, he pakari hoki ēnei whitiki, ā, ka ārai i te tohu, i te ru wera rānei i runga i ngā taonga kawe.

2. Whitiki Mata Kevlar Panihia ki te PTFE

He mata kore-piri, ātete-matū hoki te papa Kevlar kua pania ki te PTFE (Teflon). He pai ēnei whitiki mata-tuwhera mō te whakamaroke i ngā oumu, te whakamaroke PCB, me ngā raina whakamaroke kakahu. Ka taea e te kaha kume te eke ki te 3,500/3,300 N/5cm.

3. Whitiki Wēra Kevlar

He mea hanga ki te whatu Kevlar maha-paparanga me te 5, neke atu rānei ngā paparanga whakakaha. Ka ātete ki te pāmahana tae atu ki te 510°C, me te matotoru mai i te 5mm ki te 14mm. E wātea ana te whatu mutunga kore, me ngā here ā-ringa rānei.

4. Whitiki Kakahu Kevlar Panihia ki te PTFE

He papanga turanga Kevlar kua pania ki te kapia PTFE mō ngā mahi e hiahia ana ki ngā mata kore-piri me te ātete matū. Awhe pāmahana: -140°C ki te 360°C. Kaha kume tae atu ki te 1,500/1,250 N/cm.

Ngā tono matua mā te ahumahi

Te Hanga Karāhe

Ko te tono tino uaua mō ngā whitiki kawe Kevlar pāmahana teitei. Ka kawe ngā whitiki i ngā mea karāhe wera—ngā oko kakau, ngā matapihi mīhini horoi, ngā oko tēpu—mai i te hanga mīhini pēhi ki ngā wāhi whakamahana, ina tino wera te pāmahana, ā, he mōrearea tonu te ru wera. Mā te ātete wera o te whitiki ka ārai i te tohu, te karaihe, te whakarerekētanga rānei o ngā mata karāhe.

Te Whakarewa me te Tukatuka Rino

Te kawe i ngā pepa maitai wera, ngā whakarewanga whakarewa, te konganuku kua whakakāhia, me te kirinike. I roto i ngā wheketere maitai, ka taea e ngā whitiki Kevlar te whakahaere i ngā rauemi wera mai i ngā tukanga whakarewa tonu, i ngā tukanga whakapūmau rānei, me te pupuri i te āhua pai i ngā wāhi ka whakapakeketia, ka pakaruhia hoki e ngā whitiki rapa paerewa. Ko ngā whitiki Super-K® e hangai ana ki te EPDM tētahi atu kōwhiringa ātete wera, engari he kaha ake te kaha kume me te hanganga mama a Kevlar.

Te Keri me te Ahumahi Taumaha

Ka whakakapia ngā whitiki kawe keri me ngā anga Kevlar® e ngā whitiki taura polyester/nylon me te maitai tuku iho. Ko ngā painga ko te roa ake o te ora, te whakaiti i te ātete hurihuri, te iti ake o te whakapaunga pūngao, me te iti ake o ngā hononga. Ka whakaitihia e te hoahoa mama ngā tono hanganga taputapu me ngā utu whakahaere.

Ngā Mahi Whakamaroke me te Whakaora

E whakamahia ana ngā whitiki mata Kevlar kua pania ki te PTFE i roto i:

• Ngā whakamaroke moenga papatahi me ngā aho whakarara kakahu
• Ngā kauhanga whakamaroke infrared-tawhiti
• Ngā oumu whakamaroke PCB
• Ngā raina whakamaroke kai ahumahi
• Te whakarārangi takai me te whakatakoto whakaheke kakahu

Mā te hoahoa mata tuwhera ka taea te rere o te hau, ā, mā te mata PTFE kore-piri ka māmā te tuku i ngā rauemi.
