Ko te polyethylene rāpoi tiketike: tirohanga whānui, ngā āhuatanga, whānuitanga

I nga ra katoa, i roto i te ao o te mahi a te tangata whakamōhio rauemi hou whiwhi e te tikanga horihori. Ko tētahi o enei ko te polyethylene taimaha rāpoi tiketike, i te mea kua ki te 50-doma o te rau tau whakamutunga, kua riro te hua arumoni, engari kei te whiwhi i te reira rongonui tūturu noa nei.

whakaahuatanga

Ko te polyethylene taimaha rāpoi tiketike ko tetahi o nga momo o te ethylene polymerized rewarau. Ko tōna āhuatanga matua - he tino roa rāpoi mekameka. E matau ratou pai me te tuku i te pikaunga, "faitoraa" ratou taunekeneke intermolecular.

he kore rerekē i ētahi atu momo o kirihou ratou rauemi ahua. He kahore kakara, reka, e kore e riro i te reira āhuatanga paitini. Ka taea e te hanga e ia tetahi kaiwaea whakatinanatanga tae. I te wa ano kua reira he huinga o ngā āhuatanga e te wehe reira pai ki runga ki te tahi atu waerau.

Ko te polyethylene taimaha rāpoi tiketike ko te rauemi pakeke ki te kaha pānga tiketike. Ko te taea ki te tu atu ngaohiko nui nui ia. Te reira i kore e mimiti te houku, no te mea o te mea te reira e kore e pāhekoheko ki te tangata kiri a reira te mea pahekeheke. I tua atu, kua reira he ātete abrasion teitei (neke atu i te maitai) me te whakarea iti o te waku.

Ko te āhuatanga o tiketike polyethylene taimaha rāpoi

Ka rite ki kua tuhia, i te āhuatanga matua o te waerau tiketike nga mekameka rāpoi e roa. Ano, kei te hāngai ratou i roto i te ahunga kotahi. Whakaritea nui faitatau ki tahi i te tahi. whakamārama ana tēnei i te kaha o te rauemi.

Ahakoa te meka e hanga te polyethylene taimaha rāpoi tiketike mekameka roa, te hononga i waenganui i te rāpoi takitahi he ngoikore. Ko raro atu i taua o te Kevlar i te iti rawa rauemi roa tenei ahua. hanga ana tēnei āhuatanga e kore e te waerau te wera ātete - rewa reira i te pāmahana o te 144 degrees.

I roto i tenei polyethylene ui hanganga hākawa, amines rōpū hydroxyl ranei, e hanga nga rauemi i haria ki taiao kaha matū me te kino. No te mea o tenei taonga e kore he wai kaupapa, makuku, māngai pukuriri, microorganisms me hihi katinga.

Ko te tikanga matua o te tukatuka

Whakaritenga e Me hanga polyethylene nui-rāpoi, GOST 16338-85 kei. E ai ki a ratou, kawea ana te ariā o te rauemi i roto i runga i te mana o kaiwhakakökï metallocene waetahi - ethylene. Kua whakamahia hoki te hanga o ngā hua tika ki nga momo matua e whai ake nei o te maimoatanga:

1. Ko te rā-pōtaka. E konatunatua rauemi Raw ki te whakarewa. aki ana te papatipu hua te roto tatau ki te wai. tahu kakawaea kuraina i roto i oumu ki tukutahi toia me te tango i te whakarewa.
2. Hot akina me sintering. kōpeke te papatipu paura te kaha nui, ai whiwhi rauemi ōrite. Na ka ko reira wera-tukinotia - sintering i te pāmahana o te 150-200 nekehanga.
3. Rame Tangohanga. rewa te rauemi raw te ki te puranga rapa-rite ōrite, me te ka extruded roto i nozzles motuhake.

Nuinga whānui rā-pōtaka. Oia mau, i roto i tenei ara whiwhi tiketike muka polyethylene taimaha rāpoi he kaha nui.

Whakamahia i roto i te ahumahi hōia

Ko te muka whakamahia mo te hanga o tiketike waerau taimaha rāpoi Kei te whānui i whakamahia mo te hanganga o te taputapu whaiaro tiaki, i roto i ngā patu tinana. Ngā mihi ki enei āhuatanga kakawaea rite te iti te taimaha motuhake, me te tiketike kitea tukua te ahotea (te ōwehenga o enei kuputohu he 7-8 wa ki runga ake i taua o te maitai) whawhai whiwhi te marama, me te ātete ki matā, kongokonga me ētahi atu āhuatanga e totohu.

patu Body hanga o ngā rau i whiwhi e whakakotahi nga muka ki tahi i te tahi i koki rerekē. Ngā mihi ki taua hangarau puta papanga multiaxial - he ahua motuhake o te whare pungawerewere waiwai e mau taumahatanga i roto i tetahi aronga. Whakamahia ki te tiaki i te kātua me topito teitei polyethylene taimaha rāpoi. Ka taea e Āhuatanga papanga multiaxial tiaki me waka Armoured, me te te whakamahi o te muka ki te waihanga i tētahi tapahia karapu ātete.

Whakamahia i roto i te rongoā

I roto i te rongoā, whakamahia tiketike polyethylene taimaha rāpoi te nuinga mo te hanga o implants mo te hope, me te tuarā o te turi. Kua hoki te wa tuatahi kua whakamahia ai ki te whakaaro i taua i roto i tawhiti i te 1962. A mai reira ahau timata ki te nuinga.

Whānui whakamahia me whakarerekētia rauemi - reticulated polymer ripeka-hono ranei. Kei te whiwhi te reira e tiketike muka rāpoi polyethylene taimaha obstrelivaniya hihi kama irahiko ranei, e he crosslinked ki ia atu ngangana. I muri iho, e waiho i raro i te reira ki te mana waiariki, i te whakaiti i tona kaha piti hāora-whakaiti.

Muka e hāngai ana i runga i enei rauemi raw e whakamahia mō te suturing. Leader i roto i te hanga o enei hua ko te kamupene DSM, e te kaiwhakawhiwhi ki te hauora mākete miro mō hononga huaina Dyneema Haohaoa.

Whakamahia i roto i te ahumahi

Ko te tino whānui e whakamahia ana i roto i te ahumahi kua kitea he whārangi polyethylene rāpoi tiketike, tukua nei te ki te hanga mākete papa matotoru o te 2 cm. I runga i te pūtake o hangaia matapihi kirihou piha whaimana, whirihoranga pvc-rōpū, me te pvc teitei pūkete.

I roto i te engineering pūkaha mo te hanga o mowhiti taatiraa, ahunga, hanganga o nga wahi, mahi i roto i te hinu waipēhi reo ranei, a i roto i ngā pūnaha whāhauhau ki te pēhanga whakahaere tiketike, tino whakamahia nuitia nui-rāpoi polyethylene 1000 - tetahi o nga momo polymer matua.
