Njira Yopangira Zojambula Zamkuwa mu Fakitale

Ndi kukopa kwakukulu pazinthu zambiri zamafuta, zamkuwa zimawoneka ngati zinthu zosunthika kwambiri.

Zojambula zamkuwa zimapangidwa ndi makina opanga makina opangira zojambulazo omwe amaphatikizapo kutentha komanso kuzizira.

Pamodzi ndi aluminiyamu, mkuwa umagwiritsidwa ntchito kwambiri muzogulitsa zamafuta ngati zinthu zosunthika kwambiri pazitsulo zosapanga dzimbiri. Makamaka m'zaka zaposachedwa, kufunika kwa zojambulazo zamkuwa kwakhala kukukwera pazinthu zamagetsi kuphatikiza mafoni, makamera a digito, ndi zida za IT.

Zojambulazo yonama

Zojambula zazing'ono zamkuwa zimapangidwa ndi ma electrodeposition kapena ma rolling. Kuti electrodeposition mkuwa wamkuwa uyenera kusungunuka mu asidi kuti apange electrolyte yamkuwa. Njira yotereyi ya electrolyte imaponyedwa m'makombelo ena omiza pang'ono, omwe amayendetsedwa ndi magetsi. Pa ng'oma izi filimu yopyapyala yamkuwa imakhala pamagetsi. Izi zimadziwikanso kuti kupaka.

Pakapangidwe kazitsulo kopangidwa ndi ma electrodeposited, zojambulazo zamkuwa zimayikidwa pa ng'oma yozungulira ya titaniyamu kuchokera kumayankho amkuwa komwe imalumikizidwa ndi magetsi a DC. Cathode imalumikizidwa ndi ng'oma ndipo anode imizidwa mumayankho amkuwa a electrolyte. Munda wamagetsi ukamagwiritsidwa ntchito, mkuwa umayikidwa pa ng'oma pomwe imazungulira pang'onopang'ono. Pamwamba pamkuwa pamakhala bwino pomwe mbali inayo ndi yovuta. Kuthamanga kwa ng'oma kumachepetsa, mkuwa umakulirakulira komanso mosemphanitsa. Mkuwawo umakopeka ndikuwunjikira pamwamba pa ng'oma ya titaniyamu. Mbali ya matte ndi ng'oma ya zojambulazo zamkuwa zimadutsa munthawi zosiyanasiyana zamankhwala kuti mkuwa ukhale woyenera kupanga PCB. Mankhwalawa amalimbikitsa kulumikizana pakati pa mkuwa ndi ma dielectric interlayer panthawi yamkuwa yopangira lamination. Ubwino wina wamankhwalawa ndikuchita ngati anti-tarnish othandizira pochepetsa makutidwe ndi okosi amkuwa.

Chithunzi 1: Chithunzi 2 chikuwonetsa njira zopangira zinthu zamkuwa zokutidwa. Zida zogubuduza zimagawika m'magulu atatu; ndiye, mphero zotentha zokugudubuza, mphero zozizira zodzigudubuza, ndi mphero zojambulazo.

Ma coil of the thin foils amapangidwa ndikuyamba kulandira mankhwala ndi makina mpaka atapangidwa mawonekedwe awo omaliza. Chithunzi chazithunzi zakujambula kwa mkuwa chimaperekedwa mu Chithunzi 2. Mzere wamkuwa (makulidwe oyambira: 5mx1mx130mm) umatenthedwa mpaka 750 ° C. Kenako, imakhala yotentha mozungulira masitepe angapo mpaka 1/10 ya makulidwe ake oyamba. Asanaziziritse ozizira oyamba masikelo omwe amachokera pachithandizo cha kutentha amachotsedwa pamphero. Pakazizira kozizira makulidwe amachepetsa mpaka 4 mm ndipo mapepala amapangidwa kuti akhale ma coil. Njirayi imayendetsedwa m'njira yoti zinthuzo zimangokhala zazitali komanso sizisintha m'lifupi mwake. Popeza ma sheet sangathe kupangidwanso kwina (nkhaniyi yagwira ntchito molimbika kwambiri) amachiritsidwa kutentha ndipo amatenthedwa mpaka 550 ° C.
