Guryaha jirka iyo kiimikada ee biraha

Kala guryaha farsamada, jirka, farsamo iyo kiimikada ee biraha. sifo jirka cuf gaar ah, midab, conductivity korontada. Sifooyinka kooxdan ayaa sidoo kale conductivity kaamerada, dhaqanka barafka iyo cufnaanta ee biraha.

By sifooyinka farsamo waxaa ka mid ah dabacsanaan, barti, qalbi engegnaantooda aawadeed, xoog, qalleyf.

guryaha Chemical biraha ka mid ah ragaasi iska caabin ah, milmi oo lagu qayilo.

Astaamaha sida "castability", hardenability, weldability, ductility, waa farsamada.

guryaha jirka

1. Color. Biraha ha iftiin ma idlaan dhex, aan waa hufan. In iftiinka ka muuqataa, element kasta wuxuu leeyahay hooska u gaar ah - color. Ka mid ah biraha midabaynta farsamo ayaa copper iyo Alloys la kaliya. Waayo, sifo xubno kale waa cado ah oo lacag caddaan ah si ay Bula-birta.
2. Fusibility. soocista Tani waxay muujinaysaa awoodda element hoostiisa kulayl si ay u noqdaan dareere ka adag. Fusibility waxaa loo arkaa sifooyinka ugu muhiimsan ee birta. Inta lagu guda jiro kulaylinta, oo dhan biraha ka adag si ay u dareere ah. Marka qaboojinta, walax la shubay ah, kala guurka dambe - ka dareere gobolka adag.
3. conductivity korontada. dabeecad Tani waxay muujinaysaa awoodda si ay u gudbiyaan ka electrons free of korontada. conductivity korontada ee jirka biraha waa kun jeer in ka badan non-macdan ah. Iyada oo la kordhiyo heerkulka qayb hoos conductivity korontada, iyo sida heerkulka hoos u, siday u kala horreeyaan kordhiyaa. Waa in la ogaadaa in conductivity ee Alloys had iyo jeer waxay noqon doontaa hoose ka badan bir wax dhismaha daawaha.
4. guryaha magnetic. Si aad si cad u magnetic (ferromagnetic) xubno ka mid ah Cobalt kaliya, nickel, bir iyo tiro ka mid ah Alloys dhanba. Si kastaba ha ahaatee, inta lagu guda jiro kululaynta si heer kulka cayiman ayaa sheegay in walxaha lumiyaan magnetism. Alloys bir ah oo la xushay heerkulka qolka aan waa ferromagnetic.
5. conductivity kaamerada. soocista Tani waxay muujinaysaa awoodda kulaylka for guurka ka jirka ka yar kulul kululeeyo aan barakaca muuqata qayb ay dastuurka ka. heerka sare ee conductivity kaamerada ogolaanaya kulaylka iyo biraha qabow si siman oo si deg deg ah. Waxaa ka mid ah arrimaha farsamo ayaa heerka ugu sareeya ee copper.

Biraha ee kimistari mashquulin meel gaar ah. Joogitaanka sifooyinka baahisey ogolaanaya in aad isticmaasho walax ku meel gaar ah.

guryaha Chemical ah macdanaha

1. Daxalka. Daxalka loo yaqaan baabbi'inta wax by xiriirka electrochemical ama kiimiko leh deegaanka. Tusaale ahaan ugu badan waxaa loo arkaa bir abuurmeena. caabin daxalka ka mid ah sifooyinka ugu muhiimsan ee dabiiciga ah ee tiro ka mid ah biraha. Marka tan la eego, qalabka sida lacag, iyo dahab, platina, waxaa loo yaqaan sharaf leh. Waxay leedahay iska caabin ah daxalka sare ee nickel oo kale cuntrooyinka biraha. Biraha Ferrous ku xiran yihiin burburinta dhaqso iyo ka xoog badan midabka.
2. Oxidizability. dabeecad Tani waxay muujinaysaa awoodda element ah ee fal la O2 sarkhaansan yihiin wakiilada oksidheeyeyaal ah.
3. Milmi. Biraha isagoo ah milmi aan xad lahayn oo dareere ah marka adkaansho sameysmi karaa xal adag. In xal waxay atamka ka mid ah qayb gundhig ee daaqaddii crystal ah ee qaybaha kale kaliya oo ilaa xad ah.

Waa in la ogaadaa in guryaha jireed iyo kiimikada ee biraha ku jira qaar ka mid ah sifooyinka ugu muhiimsan ee arimahan.
