Aramid ngelaphu: iimpawu, iimpawu, ukhathalelo

Phakathi ezahlukeneyo izicwili kwenzeka eyolukiweyo, nejonge ukuyila iimpahla ezikhethekileyo. Amaninzi, le nto kusetyenziswa ukukhusela umntu, hayi kuphela xa esenza eziyingozi, kodwa kwiimeko kakhulu. Ngaba iimpawu ezingaqhelekanga aramid ilaphu.

Yintoni na?

Kuba mveliso a izinto ezifana usetyenziswa ifayibha aramid. inyama enjalo isagquba. Kuyinto izinto Polymer esetyenziswa njengecandelo yandisa in ngawo iimpahla.

Ngamanye amazwi, iiovaroli, vests, nezigcina-ntloko kunye nezinye izincedisi - imveliso eyenziwe aramid ilaphu. Bona bayakwazi sizikhusele iimbumbulu nomlilo. Ezi mveliso nje yabaqhubi zomkhosi kunye novavanyo, kodwa abacimi, steelworkers kunye nabanye abameli kwemisebenzi ezisongela ubomi.

A incinane

ifayibha Aramid okwesihlandlo sokuqala lwenziwa yi Dupont usomichiza inkampani American ngo-1964. Ekuqaleni, izinto ndiwazuze igama Kevlar. Ngoku yenye brand abaziintloko. iimpawu ezifanayo impahla eyayifumaneka kwi-USSR. igama layo SVM - izinto ultra-high. Emva kwethuba kwabakho imveliso Twaron.

Ukususela ngo-1970, le Kevlar beqala ukuba ziveliswe ngendlela engazange mveliso.

Apho ngefayibha zisetyenziswa

Aramid okwakha Russian-ezenziwe ngokubanzi. Namhlanje zisetyenziswa kwiindawo ezininzi. Kevlar ekuqaleni isicelo:

1. Ekwenziweni lwamavili.
2. Ifayibha ibandakanyiwe iintsontelo heavy-msebenzi kunye okusawula.
3. Le nkcazelo iye isetyenziswe njengenxalenye izakhiwo oyintlanganisela ukuze aerospace kunye noshishino moya, kulwakhiwo elwandle kunye neemoto fast, izinto eziluqilima, amagumbi soxinzelelo lwangaphakathi, kunye nezinye-high speed flywheel.
4. Ngokusekelwe amalaphu aramid sadalwa vests bullet-proof nezigcina-ntloko.
5. Imisonto nazo zisetyenziselwa izixhobo zokudlala, izixhobo zombane zasekhaya, ucikizeko, kunye nezixhobo zomculo.

iimpawu ezibonakalayo

Ilaphu Aramid uye iipropati ezizodwa. Molecule umbandela zingamakhamandela elide. It iibhondi kakhulu amide ukuba yesondo ngexesha elifanayo ngamakhonkco eziliqela enuka kamnandi. Le ukugqithisela iphambili aramid ilaphu. Ngenxa ezinjalo khompawundi kuba amandla dissociation enkulu ngokwaneleyo. Apho amakhonkco enuka ukuqinisekisa iimolekyuli eliphezulu thermostability.

Phakathi iimpawu yale ncwadana kukunika:

1. amandla High. Ilaphu Aramid iyakwazi withstanding ukuya kwi 600 kg nganye 1 mm ^2. Isalathisi Amandla izinto ingaphezulu koko ngentsimbi.
2. ukunganyangeki ubushushu High. Ilaphu Aramid kabani na iimpawu ezikhethekileyo, akuthethi anyibilike. Ukwehla kwezinga imicu uqala ngo 500 ° C. Amanqaku ekwaziyo withstanding ukuqhagamshelana emlilweni imizuzwana 50. Kulo mzekelo, eli laphu akuthethi lungaqhubeka and non-ezinokutsha. Noko ke, amandla ayo ifuthe elinjalo yehla kakhulu.
3. mninzi Low. Ilaphu Aramid ilula kakhulu, nto leyo yenza kube nje sele ekwenziweni iimpahla zokuzikhusela.
4. iindleko Low. Amaninzi, ukuthengiswa bunokubonwa ifayibha aramid. Nendleko nesondo eqhelekileyo vulu imalunga 20 zeerandi. Ubude - hayi ngaphantsi kwe-3 km.

iimpawu yengubo

Ilaphu Aramid uba index ephezulu luthambe, ngokungafaniyo izinto zeglasi kunye carbon. Yenza yewebhu ingase usebenzisa izixhobo ngokufaka oluqhelekileyo. Kulo mzekelo Imicu interlacing kungaba na. Ukongeza, eli laphu ndigqibile, ukuba oyifunayo, ukuze zipeyintwe ezinguwo nawuphi na umbala.

Aramid Ilaphu akukho eqwengiweyo nangokusebenzayo lingatshi liphele. Le nto enokumelana nomlilo, amaqondo obushushu aphezulu, i-oyile kunye izinyibilikisi imichiza. Phantsi umthwalo, ifayibha aramid ayikho zikhubazekile. Noko ke, amandla abo torsional lifinyele.

Njengoko iindleko yemeko imicu aramid, oko kumalunga $ 30 nganye-1 m ^2.

Iindawo isicelo yethishyu

Aramid lebatik lisetyenziswa namhlanje ekuveliseni:

1. izixhobo zokhuseleko kunye nempahla metallurgists, ukuwelda kunye mlilo. Ngenxa kwiipropati yayo ekhethekileyo, ilaphu isikhumba ukhusela abasebenzi ukusuka amaqondo obushushu aphezulu kakhulu wokungenela otyhidiweyo isinyithi, iintlantsi, nelangatye evulekileyo.
2. Iindlela zokhuseleko kunye nempahla abasebenzi abaninzi arhente zokunyanzeliswa komthetho kunye nabezomkhosi.
3. neentente Vzryvoukryvatelnyh kunye nezinye izixhobo.

iindleko suit yethishyu enjalo kuxhomekeke kuyilo kunye eziphathekayo uhlobo. Ixabiso le ibiza i $ 250. Noko ke, uphando lubonise ukuba best ikhusela isuti yabantu, edibanisa iimaleko amalaphu zeplastiki kunye aramid.

Indlela yokunyamekela ngelaphu

Iimveliso ezenziwe aramid ilaphu nga zihlanjwe xa kuyimfuneko. Loo nto akayeki. Noko ke, uphando olwenziweyokwakunye lubonisa ukuba ngenxa ezinjengeentlambo ngokuphindaphindiweyo, sesichengeni ngqo elangeni UV nakwimitha kwehlisa iimpawu ezisisiseko esiqwini, uqala ukuphelelwa ngamandla alo.

Ngaba singacebisi ukususa amabala phezu kwalo mbandela ngu bleaches kunye neendlela ezilungiselelwe nokucoca chemical. Bona angafundisi amandla aramid ilaphu. yokungakwazi izinto Ambhunyula, nto leyo iba ukutyabeka manzi. Kwezinye iimeko, uhlambe Kevlar ukuma kwakho ngononophelo obukhulu.
