Aramid Indwangu: izici, izakhiwo, ukunakekelwa

Phakathi ezihlukahlukene kwezicubu kwenzeka izindwangu, okuhloswe ngalo ukudala zokubhukuda ekhethekile. Ngokuvamile, le nto okokuvikela umuntu, hhayi kuphela e ukusebenza eziyingozi, kodwa futhi ezimweni ezimbi kakhulu. Ine izakhiwo okungavamile aramid Indwangu.

Kuyini lokhu?

Ukuze yokukhiqiza material ezinjalo kusetshenziswa i fibre aramid. izicubu okunjalo kwandile. Kuyinto impahla polymer esetshenziswa njengoba isakhi yokugcizelela ngezembatho womshini.

Ngamanye amazwi, ama-ovaloli, uwumnikazi wenkampani, nezigqoko, namabhantshi nezinye izesekeli - umkhiqizo eyenziwe aramid Indwangu. Bayakwazi ukuvikela kusuka zezibhamu umlilo. Le mikhiqizo hhayi ezempi kanye test pilot kuphela, kodwa futhi izicishamlilo, steelworkers kanye nabanye abameleli kuyimisebenzi ezisongela ukuphila.

Umlando omncane

fibre Aramid okokuqala sidalwe DuPont wemithi inkampani American ngo-1964. Ekuqaleni, indaba etholwe owayemuhle wayebizwa ngokuthi Kevlar. Manje ingenye brand eziholela. izakhiwo Okufanayo we indaba wawenziwe e-USSR. Igama layo SVM - impahla ultra-high. Ngemva kwesikhashana, kwakukhona umkhiqizo Twaron.

Kusukela ngo-1970, Kevlar waqala kokuba ekhiqizwa ngezinga ezimbonini.

Lapho kusetshenziswa Imicu yotshani

Aramid kudala Russian ezenziwe okwandile. Namuhla bajwayele ezindaweni eziningi. Kevlar ekuqaleni isicelo:

1. Ngo womshini amathayi.
2. Fibre likhona izindophi ezisindayo-duty futhi intambo.
3. Indaba lalisetshenziswa njengesibhedlela ingxenye izakhiwo esiyinhlanganisela ukuze aerospace kanye izindiza umkhakha, ekwakhiweni yezikebhe nezimoto okusheshayo, izinto eziqinile, yangaphakathi ingcindezi emakamelweni, kanye nezinye ligcina uthi lokuphotha luzungeza ngesivinini.
4. Ngesisekelo aramid izindwangu adalwa uwumnikazi wenkampani inhlamvu-ubufakazi nezigqoko.
5. Ukotini Wekhethelo nazo ezisetshenziselwa yezemidlalo, izinto zasendlini, yokumodela, nezinsimbi zomculo.

izakhiwo impahla

Indwangu Aramid anezakhi esiyingqayizivele. Ama-molecule ye ezibonakalayo ngamaketanga eside. It izibopho amide kakhulu zihlanganiswa ngesikhathi esifanayo izindandatho eziningana elimnandi. Lona Inzuzo enkulu aramid Indwangu. Ngenxa compounds ezifana abe dissociation amandla ngokwanele ezinkulu. Kulokhu-ke amacici elimnandi ukuqinisekisa okusezingeni eliphezulu thermostability molecule.

Phakathi nendawo le nto wukunikeza:

1. Izikhwepha High. Indwangu Aramid uyakwazi withstanding kuze kufinyelele 600 kg 1 mm ^2. Inkomba ngamandla okokusebenza kunakunoma steel.
2. High ukushisa ukumelana. Indwangu Aramid kabani izakhiwo ahlukile, akusho ancibilike. Ukucekelwa phansi kwezinga le micu iqala cishe 500 ° C. Material uyakwazi withstanding contact nge ilangabi evulekile amasekhondi 50. Kulokhu, indwangu akusho lungaqhubeka futhi okungezona oluvuthayo. Nokho, amandla nethonya layo ngaso onjalo ziyancipha.
3. inhlanganiso okuphansi. Indwangu Aramid ulula kakhulu, okwenza kube umane esisemqoka ekwakhekeni izingubo ezivikelayo.
4. eziphansi. Ngokuvamile, ukudayiswa kungabonwa ku fibre aramid. Izindleko a bobbin ejwayelekile ntambo imayelana 20 zamaRandi. Ubude - hhayi ngaphansi kuka 3 km.

Izici Indwangu

Indwangu Aramid has a Inkomba ephakeme okunwebeka, ngokungafani mathiriyeli ingilazi futhi carbon zesivikelo sesifuba. Dala webhu kungenzeka ukuthi usebenzisa ezivamile imishini ukwelukwa. Kulokhu Imicu yotshani kunokubhanqanisa kungenzeka iyiphi. Ngaphezu kwalokho, le ndwangu siphelile, uma uthanda, kungenziwa ababethi noma yimuphi umbala.

Aramid ndwangu alidabukanga futhi cishe akabi. Indaba zingamelana umlilo, izinga lokushisa eliphakeme, uwoyela kumakhemikhali awuketshezi zamakhemikhali. Ngaphansi umthwalo, fiber aramid akuyona zikhubazekile. Nokho, amandla abo torsional sinciphile.

Njengoba for izindleko kudala aramid endwangwini, kumayelana $ 30 per 1 m ^2.

Izindawo kwesicelo kwezicubu

Aramid Indwangu isetshenziswa namuhla ukwenziwa:

1. imishini Safety nezingubo metallurgists, welders nabacishi bomlilo. Ngenxa izakhiwo zayo eziyingqayizivele, Indwangu isikhumba ivikela izisebenzi ezivela ezingeni lokushisa eliphezulu kakhulu of oncibilikisiwe ekungeneni metal, izinhlansi nelangabi evulekile.
2. Esebenzisa Ukuvikelwa nezingubo abasebenzi kwabaningi ejensi wokukatelela ngomthetho futhi kwezempi.
3. amatende Vzryvoukryvatelnyh nezinye izinto.

Isudi izindleko izicubu enjalo incike ekuklanyweni kanye impahla hlobo. Intengo eshibhe kuyinto $ 250. Nokho, ucwaningo luye lwabonisa ukuthi ivikela engcono suit womuntu, ngokuhlanganisa zamatshe plastic okuphakeme ne-aramid izindwangu.

Indlela anakekele ngendwangu

Imikhiqizo ezenziwe aramid Indwangu kungenziwa wageza uma kunesidingo. Okubalulekile okunjalo a akusho shwabanisa. Nokho, ucwaningo oluningana luye lwabonisa ukuthi ngenxa nokugeza okuphindaphindiwe, ukuchayeka ngqo ilanga futhi UV imisebe zilulaza izakhiwo eziyisisekelo nezicubu, uqala ukulahlekelwa amandla ayo.

Ayitusi ukususa amabala ebusweni le nto by bleaches futhi izindlela senzelwe chemical yokuhlanza. Bona ona ngamandla aramid Indwangu. kuntuleka impahla zihlubule, okuyinto has a enamathela amanzi. Kwezinye izimo, geza Kevlar yakho imi ngokucophelela okukhulu.
