I roto i te momo o te kopa puta papanga, tikanga nei ki te hanga i kākahu motuhake. Nuinga o ngā wā, e whakamahia ana i tēnei rauemi e ki te tiaki i te tangata, i roto i te mahi o te mahi mōrearea e kore anake, engari ano hoki i roto i ngā āhuatanga tino. He āhuatanga faahiahia aramid papanga.

He aha te mea te reira?

Hoki i hangaia e te rauemi taua whakamahia te he muka aramid. He whānui taua kiko. Ko te rauemi polymer whakamahia rite te wāhanga whakapakari i roto i te kakahu hanga.

I roto i te mau parau te tahi atu, overalls, koti, potae me ētahi atu oko - he hua i hanga o aramid papanga. E taea e ki te tiaki i matā me te ahi ratou. e kore e kaiurungi anake hōia, me te whakamatautau, engari ano hoki tāmate, steelworkers me ētahi atu māngai o te mahi ora-whakawehi enei hua.

He hītori iti

I hanga muka Aramid mo te wa tuatahi e Dupont kēmihi kamupene American i roto i 1964. I te tīmatanga, ko te rauemi whiwhi i Kevlar. Na ko reira tetahi o nga rama ārahi. āhuatanga rite o te rauemi i hangaia i roto i te USSR. Ko tōna ingoa SVM - rauemi ultra-tiketike. I muri i te i reira ko te hua Twaron.

Mai 1970, tīmata te hangaia Kevlar i runga i te tauine ahumahi.

Hea e whakamahia muka

Aramid papanga o Russian-hanga whānui. I teie mahana, e whakamahia ratou i roto i ngā wāhi maha. Kevlar i tono tuatahi:

1. I roto i te hanga o potae.
2. ngā muka e i roto i te taura taimaha-ohipa me kotaha.
3. I whakamahia te rauemi rite te wāhanga o ngā hanganga hiato mō te Aerospace me te ahumahi rererangi, i roto i te hanga o parahutihuti me cars nohopuku, tūemi roa, ruma pēhanga ā-, me ētahi atu tōhito nui-tere.
4. I runga i te pūtake o papanga aramid i hanga e te koti matā-tohu me potae.
5. Kei te whakamahia hoki muka mō te taputapu hākinakina, taputapu whare, te whakatauira, me mea whakatangi.

āhuatanga rauemi

He āhuatanga ahurei papanga Aramid. Ngā rāpoi ngota o te rauemi e roa mekameka. E herea ia te reira i te nuinga o amide here i te wa ano ki te maha o mowhiti kakara. Ko te painga matua o te aramid papanga tenei. No te mea he pūngao dissociation feunga nui taua pūhui. Ai nga mowhiti kakara whakarite rāpoi thermostability tiketike.

I roto i te āhuatanga o tenei rauemi, ko te ki te whakarato:

1. kaha High. Ko te ahei o te pato ake ki te 600 kg ia 1 mm ² papanga ^Aramid. Ko te taupū kaha o te rauemi, ko te teitei ake i taua o maitai.
2. resistance wera High. papanga Aramid He ahurei nei āhuatanga, e kore e ngohe. Kinonga o nga muka tīmata i pā ana ki 500 ° C. Material taea o pato whakapā ki te mura tuwhera mō te 50 hēkona. I roto i tenei take, e kore e te papanga popo me kore-he pūkākā. Heoi, tona kaha pānga i taua he tino heke.
3. kiato iti. Ko te tino marama papanga Aramid, e hanga ana e ia mahuinga noa i roto i te hanga o te kakahu paruru.
4. utu iti. Nuinga o ngā wā, ka taea te kite i te hoko i roto i te muka aramid. Ko te utu o te maumiro paerewa o te miro, ko te pā ana ki 20 tara. Length - e kore e iti iho i te 3 km.

āhuatanga papanga

papanga Aramid he taupū teitei o elasticity, i rite ki nga rauemi o te karaihe, me te waro muka. Waihanga i te tukutuku kia whakamahi i te taputapu raranga tikanga. I roto i tenei take kia interlacing muka tetahi. I tua atu, i te papanga oti, ki te hiahiatia, e taea te pania i roto i tetahi tae.

e kore te Aramid papanga i haea a ngā kore e tahu. Ko te rauemi e taea te tu ahi, nui pāmahana, te hinu me te whakarewa matū. I raro i te uta, e kore te te muka aramid hauā. Heoi, heke ratou kaha torsional te.

Ko te utu o te papanga o muka aramid, he reira e pā ana ki $ 30 ia 1 m ^2.

Ngā wāhanga o te tono o te kiko

whakamahia Aramid papanga te tenei ra mo te hanga o:

1. taputapu haumaru, me te kakahu mo metallurgists, welders me kaikawe. Nā ki ona āhuatanga ahurei, tiaki papanga kiri kaimahi i te pāmahana tino tiketike o te tomokanga whakarewa whakarewa, korakora, me tuwhera mura.
2. Founga o te tiaki me te kakahu mo kaimahi o maha pokapū uruhi ture me te hōia.
3. teneti Vzryvoukryvatelnyh me ētahi atu taputapu.

take utu o taua kikokiko tei runga i te hoahoa me te rauemi momo. Ko te utu o te na'ina'i ko $ 250. Heoi, whakaaturia rangahau kua e tiaki pai take tangata, te whakakotahi paparanga o kirihou me te aramid papanga.

Me pēhea te ki te te tiaki i te kakahu

Ka taea te horoi Products hanga o aramid papanga ki te tika. e kore e he rauemi taua holomui. Heoi, kua whakaaturia maha rangahau e rite ki te hua o horoinga tukurua, te rongo tika ki te ra me te UV hihi haafaufaa nga āhuatanga taketake o te kikokiko, haamata te reira ki te ngaro tona kaha.

e kore e tūtohu ki te tango stains i te mata o tenei rauemi i kaihoroi me te tikanga tikanga mo te horoi matū. waimaero ratou te kaha o te aramid papanga. Taua kore o rauemi huia, e kua he paninga parewai. I roto i te tahi atu te wā, horoi koutou Kevlar tu ki te tūpato tino.
