Qiimaha Mashinka Drewiye Kaabi: Horumarinta Caafimaadka Keymuugga Siyaasadda Iibinta
Qalloocidda iyo warshadaha sanaadu waa qaybta muhimma ee loo isticmaalaa mashin khaaska ah, la sameeyo talo toosan oo la dhaxeeya qiimaha. Mashinkani way abuuraan khaasaska noocaha khaasaska ah—sida khaaska fulayska weyn ee fulayska gacanta ee dhexe, fulayska fulayska weyn ee fulayska sanaadu, iyo fulayska aluminiamka ee furfurka sanaadu. Haddii horumarinta caalamiga ah ay ku soo ammaan doonto kororarka cusub iyo dheelitirrada sanaadu, warshaduhu waa inay eegto qiimaha mashinka iyagoo la dhigaya hawlaha dherer-dhaqameed; mudulal aabeeleeya qiimaha yar iyo farsamada weyn waxay leedahay raaxo si loo gaaro dalool weyn oo khaasaska caadiga ah, taasoo noqonayo qodob muhiim ah ee ku qorsta kulaylka.
Qorsheyaasha sayniska guriga iyo elektronikada waxay iibsaan fassax dhexeeya in kordhin, halka aagga mashinka xidhida khariicda ay ku habboon tahay doonayaasha sax ah ee khariicda iyo khariicda awood u leh. Sareynta guriga wuxuu tegey mashinkan si ay u sameyso khariic cadmium yar oo loo isticmaalayo khabalka moorka, khariic dhulka dharkaaga oo loo isticmaalayo qaybta ophanging, iyo khariic aluminom oo loo isticmaalayo nidaamka elektrikuksa yar—gaar ahaan marka guriga elektrikuks (EV) u baahan tahay khariic badan oo awood u leh. Qorsheyaasha elektronikada, mashinkan wuxuu abuura khariic yar ka yar oo loo isticmaalayo qaybaha telefoonka saambanka, bogaalaha sirkaytka, iyo sensarka. Qofka korontada qorsheyaasha, aagga mashinka waxaa la waanaansanaya awoodda saxsan; mashin kheyr-ila-dhexe-ila-kolbadood waxay leedahay aagga bilowga sare, laakiin waxay ka sara khaangeli kartaa, taasoo noqonaysa mid awood u leh qaybta shabakadda korontada.
Qayamahoyinkii ka soo baxa sida taajiyadda caafimaadka iyo xoolo-tibaabada inay furto horizonto cusub oo loo isticmaali kara, halka aagga tooska warshadaha dhaawacida ay ka caawinayo sakhraacidda production-ka gaarka ah iyo u fiican qiimaha. Wajahadooyinka taajiyadda caafimaadka (sida paanelada shamsiga, turbaayndhaha cir-cirka) waxaa ugu baahan tahay wararka la'aanta korrosionka (sida copper-ka la saanayo ama korrusiyada midabka) si ay uga haysato xaaladaha waqtiyaha dibedda, haddas shakhsiga warshadaha xoolo-tibaabada waxaa ugu baahan tahay warar biocompatible-ka si ay u isticmaaleen catheters, pacemaker leads, iyo tools-ga jidhkada. Qayamahyadaas waxaa ugu baahan tahay warshadaha leh hejinta shaqsiyaadka awoodsiga leh, waxa kale haddaba aagga ay ka weyn tahay kulaylka caadi, focus-ka dugsiga ee dunida ku saabsan isku-dhafka iyo nooc-saadisinta caafimaadka wuxuu si habboon u hubin kara doonorro badan dheer-sanaad. Si aad ugu fahmataan fagaaraha aagga ka mid ka mid ah warshadaha caadi iyo warshadaha gaarka ah, waa muhiim in lagu ogaado in aad uga saaran tahay qayamahoyinka ugu badan qiimaha.
