Nichrome ulusi makamaka ntchito

Technology kwa ulimi wa kasakaniza wazitsulo wapadera zitsulo zina zamanja akhala bwinobwino kuimirira nsanganizo. Zimenezi sasiya, koma pali zina zimene akulamulirabe zipangizo zambiri makolo. Izi, makamaka, anati Nichrome ulusi umene, chifukwa osiyanasiyana wapadera makhalidwe luso ndi thupi, wapeza ntchito zosiyanasiyana mafakitale.

Nichrome ndi chiyani?

aloyi Izi aumbike mwa zitsulo ziwiri m'munsi - faifi tambala, ndipo chromium. M'menemo woyamba zina 80% ya kapangidwe ndi aloyi. Komanso zitsulo zina anadzetsa nichrome, pakati zomwe chitsulo, zotayidwa, pakachitsulo ndi ena. Sewerolo makhalidwe a zinthu monga mkulu magetsi kukana, kutentha kukana ndi ductility. Ndi makhalidwe amenewa ali pawokha chinthu chinachake chapadera zitsulo miyambo, koma Umapeza nichrome filament chifukwa osakaniza awo mu dongosolo limodzi. Mwachitsanzo, nthawi yomweyo monga ductility ndi amalola kupanga filament ulusi aloyi zina ndi kuwagwiritsa ntchito pa ng'anjo kumene madzimadzi ntchito akhale pa kutentha mu dongosolo la 1200 chinkafunika C. Komanso, malingana ndi cholinga cha aloyi mwina zina akumane ndi doping kuti kuupereka katundu watsopano kapena kusintha makhalidwe. Choncho, kuonjezera ntchito moyo nichrome kuchepetsedwa osowa lapansi zitsulo zigawo zikuluzikulu.

NKHANI nichrome filament

Pali zosintha angapo filaments nichrome, amene makhalidwe awo yapadera, koma pa mitundu yosiyanasiyana ya makhalidwe inali yomweyo yopapatiza osiyanasiyana. Mwachitsanzo, mwa mawu a osalimba a aloyi ndi pakhoma kuchokera 8200 mpaka 8500 makilogalamu / mamita ^3. Opaleshoni kutentha limafanana zopangidwa kwambiri 1000-1200˚C osiyanasiyana. Pankhaniyi, kukula kwa kufala kwa akamagwiritsa ndi yaikulu. Wotchuka kwambiri nichrome filament amene awiri ndi 0.01-0.08 mm. Palinso mankhwala kupitirira kuchuluka kwa kukula izi, koma m'malo zosiyana, cholinga ntchito mfundo za m'minda kwambiri apadera. Koma mtendere thupi, ulusi pafupifupi kuima 0,65-0,7 GPa, koma kukhalabe mlingo ayenera kuonedwa ndi kusamala technologists mawu a ntchito chitetezo cha chuma. Mwachitsanzo, ulusi sangakhoze anachoka mu mlengalenga sulfurous, kuyambira ngati sing'anga ndi zimawononga zotsatira pa katundu wa nichrome, ndi pa matabwa ake.

ulimi wa faifi tambala-chromium

Kuyamba, tiyenera anatsindika kuti ulusi ndi chimodzi mwa Nichrome akamagwiritsa kumasulidwa. Ndi wapafupi wa ku khalidwe mankhwala waya. Ndisonyezeni zinthu pressurized njira broaching. Koma pamaso opaleshoni workpiece si poyera kuti kutentha, kotero njira amatchedwa ozizira okokedwa. Zingathenso kugwiritsidwa ntchito njira etching - iwo qualitatively kusintha thupi katundu amene amalandira linanena bungwe Nichrome ulusi. Kodi ndingapeze zinthu izi? Kawirikawiri chinkhoswe mu kupanga mphero zitsulo. Koma m'pofunika kudziwa kuti ndondomeko kulenga zinthu nichrome si munthu wamba. Ichi ndi chifukwa cha mlili wa ntchito yeniyeni ndi aloyi. Komabe, pali makampani chinkhoswe katundu zitsulo, amene anaikira mu uthunthu wake wa zamitundu wotchuka kwambiri ndi zopangidwa wa filaments nichrome.

Features ya ntchito

Chifukwa zonyamula magetsi ulusi otere ntchito mu Kutentha zida. malangizowo Amayesetsanso ntchito mphamvu aloyi ndi kutentha kukana dongosolo. ulusi kuti ntchito yaing'ono ng'anjo ozungulira mawonekedwe kamangidwe. Komanso, yapeza malo ake nkhaniyi a zachipatala, kumene ntchito ngati njira stitching. Kumanga malo ndi wopanda aloyi yake yapadera. Choncho, mankhwala lathyathyathya gulu, mwachitsanzo, thovu kapena drywall, ntchito ulusi kudula nichrome mizere lopotana. Mosiyana ndi miyambo jigsaw ulusi amalola yeniyeni ndi molondola kuchita kudula kuwonongeka kwenikweni kwa workpiece lapansi. Komabe, khalidwe la chifukwa amadalira ntchito za mawonekedwe kudula zida, komanso zikhalidwe za ndondomeko bungwe.

Kodi m'malo Nichrome ulusi?

Chuma zoweta kawirikawiri anakumana ndi vuto kasinthidwe zinthu Kutentha mu zipangizo zosiyanasiyana. M'malo abwino kwambiri imatengedwa mwauzimu ntchito, amene angapezeke mu cookers magetsi, zitsulo, maketulo ena zitsanzo, ndi zina. Pa. Koma ngati mukufuna kupereka onse kutetezedwa zotsatira electrochemical, m'pofunika kunena kuti zosapanga dzimbiri. Monga mmene kumapeto, Nichrome filament kawirikawiri amakhala index yomweyo kukaniza monga zosapanga nkhaniyo, koma wotaya katundu wake woteteza mawu a makutidwe ndi okosijeni. The mulingo woyenera kwambiri njira ngati M'MALO kungakhale kudula wakale kumanga payipi, mmene ulusi ikuthandizira chagwiritsidwa zosapanga dzimbiri.

Pomaliza

Ntchito nichrome Mkhalidwe amapereka zambiri za ubwino kwa wosuta a chipangizo makamaka kapena kamangidwe. Nkhanizi sangathe nthawi zonse kupikisana ndi Akhristu mu mawu a avale kukana, koma chitetezo motsutsana kuwonongeka matenthedwe ndi kukana magetsi nachiyika pa nkhani zosiyana kale maonekedwe luso ndi ntchito. Pankhaniyi, Nichrome ulusi sayenera kuonedwa ngati njira chilengedwe kwa zipangizo zofanana. Ndiponso, ena masitampu ali kuwonetseredwa ubwino wake monga mchitidwe wa zida kudulana, ena - onse kugonjetsedwa Kutentha waya zomangamanga. Kupereka katundu zina kumadalira kupanga modifiers zina. Kwenikweni Nichrome koyera pafupifupi zimachokeradi lero, ngati ndi kuchuluka kwa makhalidwe a zida chandamale akukulira ndi zofunika consumables. Choncho pali kufunika kusintha khalidwe ndi nichrome filament.
