Kodi zinthu zabwino kwambiri zopalamula?

M'malo a metallirgy, chemistry, ndi sayansi ya zakuthupi, kusankha kumanjachochimwaZinthu ndizofunikira kuti mudziwe kupambana njira zosiyanasiyana, kuyambira zitsulo zazitali kwambiri zazitsulo zotentha ku kaphatikizidwe kambiri zotsogola ndi magalasi. Pali zinthu zingapo zochimirira zomwe zilipo, iliyonse ndi malo ake okhala ndi mapindu ake. Tiyeni tiwone zinthu zabwino kwambiri zokhudzana ndi zolimba mwatsatanetsatane:

 

Quartz zopingasa

 Milandu ya Quarz, yomwe imapangidwa kuchokera ku silika yayikulu yopanda tanthauzo, imadziwika kuti ndi mikhalidwe yawo yapadera. Amapambana pokana kutentha kwambiri, onjezerani mavuto obwera chifukwa cha asidi ndi zitsulo, ndikusungabe kukhazikika pansi pamafuta. Izi zolimbazi zimapeza niche awo akusungunuka monga silika, aluminium, ndi chitsulo. Kuphatikiza apo, mawonekedwe awo ochititsa chidwi amayenda bwino amasintha bwino. Komabe, mtundu wa ma quartz amabwera pamtengo wapamwamba.

 

Curamic zida

Mitundu ya ceramic imafanana ndi magulu awiri akuluakulu: aluminiyamu oxide cyramics ndi zirsensium oxide cirramics. Izi zolimbazi zimaperekanso kukana kwa kutentha ndi kukhazikika kwamankhwala, kuwapangitsa kupanga zisankho zokhazikika chifukwa cha zida zambiri, kuphatikiza zitsulo ,galasi, glaramic, ndi zina zambiri. Komabe, kukana kwawo kutentha kwawo kumakhala kotsika kuposa kambiri ka quartz, zomwe zimawapangitsa kuti azikhala oyenereradi zinthu zosungunuka zomwe zili m'munsi mwa 1700 ° C.

 

Ziphuphu zojambula

Zovala zojambulajambula ndizomwe zimachitika kutentha kwambiri, malo okhala ndi mapiko ambiri, nthawi zambiri amagwira ntchito monga zida zofunikira pazitsulo zosafunikira komanso zamankhwala. Izi zolimbazi zikupezeka m'mitundu iwiri yoyambirira: Zachilengedwe zojambula ndi zodzikongoletsera. Mphamvu zachilengedwe zojambulajambula zanyama zimadzitamandira kwambiri komanso kukana kwamphamvu, kugwiritsa ntchito njira zambiri zamagetsi. Kumbali inayo, ziphuphu zojambula zokongola ndi zotsika mtengo koma zimatha kuchepetsedwa pang'ono ndi kukana kuwonongeka.

 

Ziwawa Zitsulo

Ziwawa zachitsulo zimapangidwa ndi zida zokhala ngati chitsulo chosapanga dzimbiri, molybdenum, platinamu, ndi zina zambiri. Iwo ndi omwe akupita kukachita ndi zida zosenda kwambiri ndi mfundo zapadera kapena mukakumana ndi acidic kwambiri kapena alkaline. Zingwe zachitsulo zikuwonetsa kukana kwamphamvu kuti zisawonongeke komanso kukhala ndi bata lokhazikika. Komabe, kugwiritsa ntchito kwawo kumalumikizidwa ndi mtengo wapamwamba poyerekeza ndi zina zopachikidwa.

 

Swammanda

TAkusankha zinthu zolimba ziyenera kuthamangitsidwa ndi zinthu zomwe zakonzedwa komanso zosungunuka. Mtundu uliwonse wa chibwibwi umapereka mwayi wake wapadera, ndipo kusankha woyenera ndi wofunikira kwambiri chifukwa chokwaniritsa zotsatira zapamwamba komanso zamankhwala, ndi sayansi yathupi.
