Melting point - xa wonke

Njengoko yaziwa, naziphi na izinto inokuba sukube, eqinileyo kunye engamanzi, kwaye sishintshe ukusuka kwimo enye ukuya kwenye. Kwanele ukuba ukukhumbula amanzi. Ngokuqhelekileyo kwiqondo lobushushu HIV ulwelo kwi negative - eqinileyo, kwaye xa amaqondo obushushu aphezulu, nokuba litshatshazi, laba umphunga, ngamanye embusweni sukube. Ukutshintsha ukusuka okuqinileyo ukuya kwimeko ulwelo kuthiwa yokunyibilika kunye lobushushu apho le nkqubo lwenzeka - kwiqondo lokunyibilika.

wenza njani inkqubo ukunyibilika? Xa siqwalasela metal, sifumanisa ukuba isakhiwo yayo yi yeglasi emkhusaneni-athom ukuba zicwangciswe ngendlela isalamane ethile omnye komnye, ukwenza okunzulu ezincinane. Xa kokufumana energy lwangaphandle okanye amandla ubushushu atom na ukunyuka umzimba, baze baqalise ukuba oscillate kunye namandla awo enkulu. Xa iqondo lobushushu emzimbeni kunye nobushushu yokunyibilika ka iziyobisi alingane, inkqubo wentshabalalo lobume metal iqala, ngamanye inkqubo ukunyibilika le.

Noko ke, oko waqalisa inkqubo yokunyibilika akuthethi ukuba ziqhube ngokwayo. Ukugcina kuyimfuneko ukuba gqolo kubonelela ubushushu kungachithwa ukutshatyalaliswa imixokelelwane ngembonakalo yikristale ngekroba.

Zonke izinto zazo. Kwaye metal ngalinye kwithempritsha yayo yokunyibilika lakhe. Ixhomekeka yikristale emkhusaneni nokwakhiwa mbandela. Izinto ehlambulukileyo ubushushu yedwa, aluminiyamu, eyenziwe ngentsimbi ezininzi - omnye. Umzekelo, indawo intsimbi ukunyibilika 1100-1130 ° C. Loo uluhlu lwamaxabiso emiselwe into yokuba umxholo ubumdaka kule wentsimbi itshintshiwe, koko, akhiwa ngokufudumeza le oxides eliyinjubaqa. Zinelungelo indawo yokunyibilika ngaphezu koko yentsimbi.

Ngokuba nobhedu lobushushu 1084 ° C, ukuze zinc - 419 ° C. Ingongoma yokunyibilika sobhedu ekubeni intsila sobhedu nezinki - 1000 ° C. Loo sentengo lobushushu kuxhomekeke yokuba kuxhomekeke kwipesenti umxholo kwamalungu. Ukuba ukwakheka ingxubevange lubhedu ngakumbi, oku kuya kukhokelela ekubeni lobushushu yokunyibilika ingxubevange liya kuba ngaphezulu ukuba zinc ngakumbi - ngezantsi.

Kufuneka kuqatshelwe ukuba iqondo lobushushu apho iziyobisi inyibilikiswa, kuxhomekeke nje kuphela yokusulungeka, kodwa kwi uxinzelelo. Noxinzelelo okwandayo, kwenyusa xa xi kunciphisa.

Njengoko sele kukhankanyiwe, bayinyibilikisa igalelo rhoqo ubushushu kuyimfuneko. Ukuziqhelisa, kubonakala ukuba kukho zokufudumeza lomgadi eziphathekayo, kodwa amaqondo obushushu lihlala rhoqo. Yaye kuphela emva kokuba imali ethile lowo uwutshisileyo ubushushu, ngokuba ukuvutha Fusion, kuza kwandisa kwamaqondo obushushu, kodwa into engamanzi.

Kukho nenye inkalo kwi ukunyibilika zesinyithi. Ukuba uyayeka unikezelo ubushushu, umsebenzi ukunyibilika le nto wayeka kwaye inkqubo umva - intsimbi ulwelo ingena karhulumente esiqinileyo. Le nkqubo ibizwa ngokuba crystallization. Kwi olupholisa intsimbi ulwelo kunye nokwenza kube okuqinileyo yakhupha imali efanayo ubushushu leyo Lonakele ngexesha yokunyibilika yayo.

Indima Fusion kwindalo, inzululwazi neteknoloji kunzima ukuba zazi. Ngokusebenzisa le nkqubo, singakwazi ukufumana isinyithi okanye aluminium ngempahla ezinqwenelekayo. Phantse yonke lasisiseko senkcubeko yoluntu isekelwe phezu intsimbi kunye aluminium zayo, yaye ngenxa yoko phezu constants ebonakalayo ezifana kwiqondo lokunyibilika. Ngapha koko, phantse akukho shishino enye nto leyo liphele metal.

Ngoko wajonga yintoni ubushushu yokunyibilika, sizimisele oko kuxhomekeke, yaye wachaza inkqubo ngokunyityilikiswa. Eli nqaku kwakhona inika inkcazelo crystallization zesinyithi.
