Kuvunguza Nichrome: izici, isicelo

Nichrome yasungulwa ngo-1905, u-Albert Marsh, okuyinto uxhuma nickel (80%) kanye chromium (20%). Namuhla sekunoFakazi eziyishumi ukushintshwa Alloys amamaki ezehlukene. Njengoba dopants letengetiwe aluminium, manganese, insimbi, Silicon, titanium, molybdenum, futhi t. D. Ngenxa izimfanelo zalo ezinhle lokhu metal iye kabanzi ukwenziwa Ihluzo Elingafaki Ukuqoka.

Basic izinga Nichrome

Nichrome lihlukile:

• okusezingeni eliphezulu ukushisa ukumelana. impahla yayo mechanical musa ukushintsha ngamazinga ashisa kakhulu;
• plasticity, okuvumela kukhishwe ingxubevange Nichrome Kuvunguza wire, iribhoni, intambo;
• lula ukucubungula. Imikhiqizo ezenziwe Nichrome ashiselwe kahle, wanyathela;
• ukumelana ukugqwala ezindaweni ezihlukahlukene.
• okusezingeni eliphezulu ukumelana nichrome.

izakhiwo Key

• I kwabantu ka 8200-8500 kg / M3.
• Ukuma nichrome - 1400 C.
• Maximum Ithempelesha yokusebenzela - 1100 ° C.
• Ukuvikeleka - 650-700 MPA.
• I resistivity nichrome 1,05-1,4 ohms.

Ukumaka wire Nichrome

wire Nichrome - okokusebenza ephelele ezihlukahlukene kagesi Ukushisa izakhi, ezisetshenziswa cishe zonke izimboni. Cishe zonke kulelo nalelo khaya heater inezici eyenziwe nichrome.

incwadi Ikhodi wire:

• "N" - lisetshenziswa Ukushisa izakhi.
• "C" - isetshenziswa izakhi ukumelana.
• "ELITJHUMI" - senzelwe ijabulise heater kagesi.

Ngokusho namazinga kazwelonke, kukhona brand eziningana ezinkulu:

• Double wire Cr20Ni80. Ukwakheka ingxubevange zihlanganisa: nickel - 74% chromium - 23% kanye no-1% yensimbi, i-silicon kanye manganese.
• H15N60 Kathathu. Ingxubevange siqukethe 60% nickel futhi 15% chromium. Esesithathu ingxenye - yensimbi (25%). yensimbi ingxubevange ukugcwaliswa kungaba kakhulu ukunciphisa izindleko nichrome, intengo zazo impela high, ngenkathi sigcina ekushiseni kwalo ukumelana. Ngaphezu kwalokho, kwandisa workability yayo.
• Eshibhe inketho Nichrome - Kh25N20. Lokhu ingxubevange okunothe lapho izakhiwo mechanical kuyagcinwa, kodwa izinga lokubanda ukusebenza kukhawulwe 900 ° C.

Ukusetshenziswa nichrome

Ngenxa izinga layo kanye azifani imikhiqizo nichrome singasetshenziswa lapho ukuthembeka kudingekile, ukuqina, ukumelana imvelo amakhemikhali nolaka futhi amazinga okushisa aphakeme kakhulu.

Kuvunguza Nichrome kanye wire ziyingxenye ebalulekile cishe zonke izinhlobo Ukushisa amadivaysi. Nichrome elikhona into yokucocobalisa, Amabhikawozi, heater, Ohhavini. Ingxubevange futhi wathola isicelo e resistors futhi ezisebenza ngaphansi ukushisa okukhulu. Kube Nichrome kanye Isibani sikagesi kanye yensimbi nokunamathisela ngomthofu. Kuvunguza Nichrome ifa baphikisana kakhulu nokushisa ukumelana, okuvumela ukusetshenziswa kwabo okusezingeni eliphezulu lokushisa amaziko omiswe bese labadubuli.

Isetshenziswa kanye Scrap Nichrome. Yena elicibilikile phansi, kanye material uya emuva ku ibhizinisi. nickel-chromium ingxubevange elisetshenziswa laboratories zamakhemikhali. Lokhu Ukwakheka akasabeli nge acid kakhulu futhi alkalis. Sikhubazekile Ukushisa Nichrome Kuvunguza isetshenziswa ugwayi electronic.

Kuqhathaniswa ngaphambilini ukusetshenziselwa lokhu yensimbi injongo, imikhiqizo Nichrome kuphephe, akusho yenhlansi, akusho nokugqwala, ayinayo ingxenye spliced.

Ukuma nichrome 1400 ° C, ngakho lapho upheka akuyona wazizwa iphunga futhi intuthu.

Onjiniyela asaphenya sezindawo eziyingqayizivele le nto, sanda kwenkululeko uhlelo lwayo lokusebenza.

Ekhaya, bentambo Nichrome isetshenziswa womshini ezenziwe ekhaya imishini, jigsaws futhi bezihlahla, ezifana, isibonelo, umshini ukusika Foam noma ngokhuni, insimbi nokunamathisela ngomthofu, idivayisi for izinkuni evutha, imishini Welding, heater yasekhaya, nokunye. D.

Ethandwa kakhulu futhi wacabangela wire Cr20Ni80 H15N60.

Ngingalutholaphi ukuthenga wire Nichrome

Ukuqala kokusetshenziswa kwalo mkhiqizo ikhiqizwa ohlobo (ikhoyili, ohlobo lwe) noma ngesimo tape. I Ingxenye evundlile ucingo nichrome kungaba ngesimo okweqanda, umbuthano, isikwele kanye trapezoid, ububanzi ungaphakathi uhla kusuka 0.1 kuya 1 milimitha.

Ngabe sithola noma thenga imikhiqizo kusuka nichrome? Siphakamisa ukuba ucabangele ezivamile kanye ongakhetha kunokwenzeka:

1. Okokuqala, ungaxhumana nenhlangano, ukhiqiza mikhiqizo kanye oda. Thola ikheli esiqondile amabhizinisi okunjalo kungaba e ekhethekile okubhekiselwa ku izimpahla namasevisi atholakala cishe kuzo zonke emadolobheni amakhulu nasemadolobheni. I-opharetha uzokwazi ngitshele lapho ukuthenga, futhi unikeze inombolo yocingo. Ngaphezu kwalokho, ulwazi mayelana ezahlukene imikhiqizo enjalo zingatholakala kumawebhusayithi ezisemthethweni abakhiqizi.
2. Thenga Nichrome izihloko ezitolo ezikhethekile kungaba, isibonelo, ukuthengisa izingxenye umsakazo, ukwaziswa okuzocatshangelwa abaculi ezifana "izandla unamakhono" nokunye. D.
3. Ukuthengwa kusuka ngabanye ezizimele ukuthengisa izingxenye umsakazo, izingxenye ezisele kanye neminye imikhiqizo metal.
4. Kunoma yikuphi esitolo sezinto zokwakha.
5. Ezimakethe ungathenga noma eliphi iyunithi ubudala, isibonelo laboratory rheostat, futhi uthathe Nichrome.
6. Nichrome wire lungatholwa ekhaya. Ngokwesibonelo, esenziwe hotplate Kuvunguza.

Uma ufuna ukwenza i-oda enkulu ke ofanele kakhulu ukhetho lokuqala. Uma udinga esincane Nichrome wire, zonke ezinye izinto uhlu kungabonwa kuleli cala. Uma ukuthenga njalo kumelwe asinake mshini.

Nichrome coiling Kuvunguza

Namuhla Nichrome Kuvunguza liyisici esibalulekile of heater eziningi. Ngemva lwaluyophola Nichrome uyakwazi ukugcina plasticity yazo, zenza Kuvunguza elinama enjalo zisuswe kalula ukushintsha ukwakheka kwalo noma, uma kunesidingo, ulungise usayizi ezifanele. Kuvunguza izinkampani wenziwa khona ngaphansi kwezimo zezimboni ngendlela okuzenzakalelayo. Ekhaya, ungakwazi futhi afeze manual emazombezombe. Ake sicabangele indlela yokukwenza.

Uma nemingcele ebaluleke kakhulu usuqedile Nichrome Kuvunguza zisesimweni yayo ukusebenza, lapho izinkampani kungaba axazulule, ngomqondo ongokomfanekiso, "amehlo". Ukuze wenze lokhu, khetha inombolo oyifunayo ematfuba kuncike wire Ukushisa nichrome, le Kuvunguza kuhlanganise ngezikhathi kunethiwekhi, futhi ngokwandisa noma ukunciphisa inani ematfuba. Le nqubo emazombezombe silula, kodwa kungase kuthathe isikhathi eside, futhi ngaleyo ndlela iyingxenye Nichrome esichithekayo.

Ukuze uthuthukise kalula futhi ukunemba ekubalweni Kuvunguza emazombezombe, ungasebenzisa wokubala ekhethekile inthanethi.

Ibala inani elidingekayo ematfuba kungenzeka ukuqala emazombezombe ku induku. Hhayi ukusika wire kumele ixhunywe ngokucophelela ikhoyili nichrome ukuba umthombo voltage. Khona-ke hlola ngokunemba we izibalo wathola Kuvunguza emazombezombe. Kubalulekile ukukhumbula ukuthi i-lemiklamo elibiyelwe emazombezombe obuphelele ukuba sanda ngengxenye yesithathu kulesi sibalo amagugu okuholela.

Ukuqinisekisa elifanayo ekujikiseni eduze we emazombezombe ukuba iphathwe izintambo ezimbili - owodwa nichrome, kwesibili - noma ithusi noma se-aluminium, ngenhloso ububanzi okuyinto ilingana imvume oyifunayo. Lapho emazombezombe iphelile, bentambo asizayo kumele kube ngokucophelela emoyeni.

Izindleko nichrome

Okuwukuphela ethile, okuyinto has a Nichrome - intengo. Ngokwesibonelo, ingxubevange kanambambili lapho uthenga okudayisa balinganiselwa ku ruble mayelana 1,000 kilogram per. Izindleko a ligature emamaki Nichrome - ruble mayelana 500-600.

isiphetho

Nge ukukhiqizwa nickel-chromium, kubalulekile ukuba acabangele idatha ye-akhawunti ukubunjwa amakhemikhali umkhiqizo kwezinhloso zenzuzo, futhi ukumelana layo kagesi, ubunjalo bomzimba ububanzi, cross-section, ubude nokunye. D. Kubalulekile futhi ukubuza amabhuku afanele. Futhi, udinga ukwazi zibukeke lihlukaniswe ingxubevange, ngomqondo ongokomfanekiso, "izimbangi". Ukukhetha impahla Proper kuyisihluthulelo nokwethenjelwa kagesi.
