Aramid lesela: makgetheng, thepa, tlhokomelo

Har'a mefuta e fapaneng ya lisele tse le hlaha masela, e reretsoe ho etsa liaparo tse khethehileng. Hangata ka ho fetisisa, boitsebiso boo e sebelisoa ho sireletsa motho, e seng feela ka tshebetso ya mosebetsi le kotsi, empa hape le maemong a feteletseng. E na le thepa e sa tloaelehang aramid lesela.

ha e le eng?

Bakeng sa ho etsa thepa ea lintho tse joalo e sebediswa e aramid faeba. dinama tse nyenyane tse joalo ho atile. Ke polymer lintho tse bonahalang e sebelisoa e le eketsa karolo ka proizvodnje liaparo.

Ka mantsoe a mang, overalls, beilwe, lihelmete le ya disebediswa tse kathoko tse ling - sehlahiswa entsoe ka lesela aramid. Ba ba khona ho sireletsa ho tswa ho likulo le mollo. lihlahisoa tsena ha feela sesole le teko bakhanni, empa hape ithuthuntshitsweng, steelworkers le baemeli ba bang ba mesebetsi e behang bophelo kotsing.

A histori hanyane

Aramid faeba ka lekhetlo la pele o ne a bōpiloe ke Dupont setsebi sa k'hemistri American khampani ka 1964. Qalong, lintho tse bonahalang a fumana e ile ea bitsoang Kevlar. Hona joale ho ke ke e mong oa Brands pele. Similar thepa ya lintho tse bonahalang tse o ile a etsoa USSR. lebitso la lona SVM - marang-phahameng tse bonahalang. Ka mor'a nakoana ho ne ho sehlahisoa sa Twaron.

Ho tloha ka 1970, Kevlar ile ka qala ho etsoa ka tekanyo e liindasteri.

Moo likhoele li sebediswa

Aramid lesela la Russia e entsoeng atile. Kajeno di sebediswa libakeng tse ngata. Kevlar qalong o ne a etsa kōpo:

1. Ka tlhahisong ea lithaere.
2. Faeba e kenyelelitsoe liropo boima-mosebetsi le slings.
3. lintho tse bonahalang tse o ile a sebelisoa e le motsoako oa mehaho e le likarolo tse ngata tsa Aerospace le indasteri lifofane, ka kaho ea yachts le likoloi le tiile, tsoarellang dintho, likamore tse ka hare ho hatelloa ke batho ba bang e phahameng-lebelo flywheel.
4. Motheong oa masela aramid li ile tsa bōptjoa ke beilwe kulo-bopaki le lihelmete.
5. Masela a boela a sebelisa bakeng sa thepa ea lipapali, lisebelisoa ka tlung, modelling, le liletsa tsa 'mino.

thepa tse bonahalang

Aramid lesela na thepa e ikhethang. Limolek'hule tsa lintho tse bonahalang tse tse telele liketane. Ho fetisisa amide litlamo tse bonded ka nako e tšoanang le masale a 'maloa nkhang hamonate. Sena ke Molemo ka sehloohong sa lesela aramid. Hobane metsoako joalo ba le ka ho lekaneng kgolo dissociation matla. Moo meheleng nkhang hamonate netefatsa limolek'hule phahameng thermostability.

Har'a thepa ea boitsebiso boo ke ho fana:

1. Phahameng matla. Aramid lesela khonang ho withstanding kg 600 ka 1 limilimithara ^2. The matla index of lintho tse bonahalang tse ke phahameng ho feta tsa tšepe.
2. Phahameng mocheso ho hanyetsa. Aramid lesela bao thepa tse ikhethang, ha qhibiliha. Ho senyeha ha ya likhoele qala hoo e ka bang 500 ° C. Boitsebiso bo ka khona ho withstanding kopana le e lelakabe bulehileng bakeng sa metsotsoana 50. Tabeng ena, lesela ha smolder le batho bao e seng chang. Leha ho le joalo, khahlamelo e matla tsa lona ka jwalo haholo tsa fokotswa.
3. Tlaase segokanyipalo. Aramid lesela o bobebe haholo, e leng se etsang hore re mpa re ba bohlokoa haholo ho tlhahisong ea liaparo e sireletsang.
4. Varaa. Hangata ka ho fetisisa, ho rekisa ka bonoa ka aramid faeba. Litsenyehelo tsa ho ba le maemo a bobine ea khoele e ka bang 20 liranta. Bolelele - seng ka tlase ho 3 km.

Features lesela

Aramid lesela o na le li-index e phahameng ea elasticity, ho fapana le ka thepa ea khalase le k'habone likhoele. Bopa ho web le ka ho ba sebedisa tloaelehileng loha thepa. Tabeng ena interlacing likhoele le ka ba le leha e le efe. Ho phaella moo, lesela fela, haeba a lakatsa, ka penta ka mmala efe kapa efe.

Aramid lesela e sa tsekolotsoeng le hoo e batlang e ha e chesa. lintho tse bonahalang tse ka mamella mollo, mocheso phahameng, oli le solvents lik'hemik'hale. Tlas'a mojaro, le aramid faeba ha a holofala. Leha ho le joalo, matla a bona torsional e fokotsehile.

Ha e le theko ea lesela la likhoele aramid, ho ke ke ka $ 30 ka ho ya ka 1 limithara ^2.

Libakeng tsa kopo ya dinama tse nyenyane tse

Aramid lesela e sebediswa kajeno bakeng sa ho hlahisa:

1. thepa Safety le liaparo tsa metallurgists, welders le ralitima-mollo. Ka lebaka la thepa ea lona e ikhethang, lesela letlalo sireletsa basebetsi ho tswa mocheso ho fetisisa phahameng tsa tšepe kenoang entsoeng ka ho qhibilihisoa, litlhase, 'me lelakabe bulehileng.
2. Mokhoa oa ho sireletsa le ho liaparo bakeng sa basebeletsi ba tse ngata mekhatlo ea coercion molao le sesole.
3. litente Vzryvoukryvatelnyh le thepa e 'ngoe.

sutu theko ea dinama tse nyenyane tse joalo itšetlehile ka mofuta moralo le lintho tse bonahalang. Theko ea maleewana ke $ 250. Leha ho le joalo, phuputso e bontša hore molemo ka ho fetisisa ho sireletsa sutu ea batho, kopantseng magato aa polasetiki le aramid masela.

Tsela ea ho hlokomela lesela

Products entsoe ka lesela aramid ka hlatsoa haeba ho hlokahala. Joalo tse bonahalang le ha ikhule. Leha ho le joalo, lithuto tsa tse ngata li bontšitse hore ka lebaka la washings khafetsa, ho pepesehela ka ho toba letsatsi le UV mahlaseli degrade le thepa ea motheo ea dinama tse nyenyane tse, ho qala ho lahleheloa ke matla a lona.

Ha e ho kgothaletsa ho tlosa litsila tse teng ho tloha holim 'a lintho tse bonahalang sena ka bleaches le ho bolela o ne a rerile bakeng sa ho hloekisa lik'hemik'hale. Ba tsa fokodisa matla a lesela aramid. Joalo ho hloka lintho tse bonahalang hlobolisa, e leng o na le barbotage sa keneleng metsi. Maemong a mang, ho hlatsoa Kevlar hao a eme le hlokolosi feteletseng.
