Kodi olemba engineering amapangidwa bwanji?

Zida
	Cholembera nsonga Pali mitundu inayi yazinthu zomwe zimagwiritsidwa ntchito popanga maupangiri aukadaulo: chitsulo cholimba, chitsulo chachitsulo, tungsten carbide, ndi chitsulo cha diamondi. Chizindikiro thupi Thupi la wolemba uinjiniya litha kupangidwa kuchokera kuzinthu zingapo, zomwe zimakonda kukhala zitsulo kapena aluminiyamu. Olemba zitsulo ali ndi nickel-plated for corrosion resistance, pamene matupi a aluminiyumu amatha kukhala anodized, ngakhale kuti izi ndizovuta kwambiri. Olemba ena otsika mtengo amakhala ndi thupi la pulasitiki la PVC.
Kutentha kwaukhondo
	Chithandizo cha kutentha ndi kutentha ndi njira zopangira zomwe zimagwiritsidwa ntchito posintha mawonekedwe achitsulo ndi zinthu zina. Chithandizo cha kutentha chimakhala ndi kutentha kwachitsulo mpaka kutentha kwambiri ndikuumitsa (kuzizira kofulumira). Izi zimawonjezera kuuma kwachitsulo, koma nthawi yomweyo zimapangitsa kuti zikhale zovuta kwambiri.
mkwiyo
	Kutentha kumachitidwa pambuyo pa chithandizo cha kutentha komanso kumaphatikizapo Kutenthetsa zitsulo, koma kutentha kochepa kusiyana ndi kutentha kwa kutentha, kutsatiridwa ndi kuzizira pang'onopang'ono. Kuumitsa kumachepetsa kuuma ndi kuphulika kwachitsulo, kumawonjezera kulimba kwake. Poyang'anira kutentha komwe chitsulo chimatenthedwa panthawi yotentha, kukhazikika komaliza pakati pa kuuma ndi kulimba kwachitsulo kungasinthidwe.
	Chifukwa chiyani kutentha ndi kutentha kuli kofunika kwa mainjiniya opanga? Malangizo a zolembera za uinjiniya amathandizidwa ndi kutentha kuti awaumitse. Kuwumitsa uku ndikofunikira kuti nsonga ikhale yovuta kuposa ntchito yomwe imagwiritsidwa ntchito, kulola nsongayo kujambula mzere. Olembawo amawumitsidwa pang'ono kuti achotse zina mwazovuta zomwe zimaperekedwa panthawi yotentha kuti zisawonongeke panthawi yogwiritsira ntchito.
nickel plating
	Nickel plating ndi pamene chinthu (kawirikawiri chitsulo) chimakutidwa ndi faifi tambala. Izi zitha kuchitika pazifukwa zingapo monga chitetezo cha dzimbiri, kukana kuvala komanso mawonekedwe.
	electroplating Kupaka kwa nickel kumachitika kawirikawiri ndi njira yotchedwa electroplating, yomwe nthawi zina imatchedwa electroplating. Izi zimachitika poyika workpiece mu njira ya electrolyte pomwe imatchedwa cathode pamodzi ndi ndodo ya faifi tambala yomwe imatchedwa anode.
	Kuthamanga kwachindunji kumagwiritsidwa ntchito ku anode ndi cathode, chifukwa chake anode imayendetsedwa bwino, ndipo cathode imayimbidwa molakwika. Maoni a nickel mu electrolyte amakopeka ndi cathode ndikuyika pa workpiece pamwamba. Ma ion awa mu electrolyte amasinthidwa ndi ayoni a nickel anode, chifukwa chake anode ya nickel imasungunuka mu electrolyte.
	Chophimba chopanda magetsi Kupaka mankhwala sikufuna kugwiritsa ntchito magetsi. M'malo mwake, preform imayikidwa mu njira yamadzimadzi yomwe imakhala ndi nickel ions, ndipo chochepetsera (nthawi zambiri sodium hypophosphite) chimawonjezeredwa ku yankho.
	The workpiece pamwamba amachita ngati chothandizira zimene anachita, kuchititsa nickel ayoni njira kusungitsa pa workpiece. Njira yamadzi yokhala ndi ayoni ya nickel imatha kutenthedwa mpaka pafupifupi 90 ° C kuti ifulumire.
	Kodi ubwino ndi kuipa kwa njira iliyonse yokutira ndi chiyani? Chemical plating imapanga faifi tambala yofanana komanso yofananira kuposa plating, makamaka pamabowo, ndi m'mphepete mwa zogwirira ntchito. Kupaka mankhwala sikutanthauza kuti workpiece ikhale ndi mphamvu, kotero kuti tizigawo tating'ono tating'ono titha kuphimbidwa mosavuta nthawi imodzi mu njira yamadzimadzi. Komabe, electroplating nthawi zambiri ndi njira yotsika mtengo yopangira zinthu.
Anodizing
	Anodizing ndi pamene chitsulo (kawirikawiri aluminium kapena magnesium) chimakutidwa ndi wosanjikiza wokhazikika wa oxide panthawi ya electrolysis. Anodizing itha kugwiritsidwa ntchito poteteza dzimbiri koma imagwiritsidwa ntchito kwambiri pakukongoletsa.
	Kodi anodizing imachitika bwanji? Anodizing imachitika kudzera mu njira yotchedwa electrolysis. Izi zimaphatikizapo kuyika chogwirira ntchito mu electrolyte ya acidic komwe imakhala anode ikalumikizidwa ndi terminal yabwino yamagetsi a DC. Cathode yachitsulo imayikidwa mu electrolyte ya acidic ndikulumikizidwa ku terminal yoyipa ya gwero la DC.
	Kuyenda kwapano kumayambitsa kusinthika kwa gasi wa haidrojeni pa cathode yoyipitsidwa moyipa ndi okosijeni pa preform ya anode, yomwe imapanga wosanjikiza wa alumina pa preform. Komabe, wosanjikiza wa alumina umadzazidwa ndi pores ang'onoang'ono omwe amatha kulimbikitsa dzimbiri. Kenako timabowo timeneti timadzaza ndi utoto wamitundumitundu ndi zinthu zoletsa corrosion inhibitors, zomwe zimapatsa ziwalo za anodized mitundu yosiyanasiyana.
Ndi zinthu ziti zomwe zili bwino?
	Zolemba za thupi la PVC sizichita dzimbiri, koma nsonga za zolemberazi nthawi zambiri sizingasinthidwe, motero sizoyenera kwa iwo omwe akufuna kugwiritsa ntchito chida cholembera pafupipafupi. Olemba thupi lachitsulo amatha dzimbiri ngati alibe nickel, zomwe zingayambitse mavuto ndi makatiriji omwe amawapangitsa kupanikizana, kotero kusintha nsonga kungakhale kovuta kwambiri. Olemba aluminiyamu alibe zovuta zachitsulo kapena PVC, koma anthu ena amawapeza pang'ono ndipo amakonda olemba olemera kwambiri. Izi, ndithudi, ndi zokonda zaumwini.
