Wazi kangakanani “ngepuleti yokushisisa”?

I-Heating plate:Iguqula amandla kagesi abe amandla ashisayo ukushisisa into. Kuwuhlobo lokusebenzisa amandla kagesi. Uma kuqhathaniswa nokushisa okujwayelekile kukaphethiloli, ukushisa kukagesi kungathola izinga lokushisa eliphakeme (njengokushisa kwe-arc, izinga lokushisa lingaba ngaphezu kuka-3000 ℃), kulula ukufeza ukulawulwa kokushisa okuzenzakalelayo nokulawula kude, inkomishi yokushisa kagesi yemoto.

Kungenziwa evuthayo into ukugcina ukusatshalaliswa lokushisa ethile njengoba kudingeka. Ukushisa kukagesi kungashiswa ngqo ngaphakathi kwento ezoshiswa, ngaleyo ndlela ukusebenza kahle kokushisa okuphezulu, isivinini sokushisa esisheshayo, futhi ngokuya ngezidingo zenqubo yokushisa, ukufeza ukushisa okufanayo okuphelele noma ukufudumeza kwendawo (okubandakanya ukushisa kwendawo), kulula ukufeza ukushisa kwe-vacuum kanye lawula ukushisa komkhathi. Enqubweni yokushisa kagesi, igesi ekhishwayo ekhiqizwayo, izinsalela kanye ne-soot kuncane, okungagcina into eshisayo ihlanzekile futhi ingangcolisi imvelo. Ngakho-ke, ukushisa kukagesi kusetshenziswa kabanzi emkhakheni wokukhiqiza, ucwaningo nokuhlola. Ikakhulukazi ekukhiqizeni i-crystal eyodwa kanye ne-transistor, izingxenye zemishini kanye nokucinywa kwe-surface, ukuncibilika kwe-iron alloy kanye nokukhiqizwa kwe-graphite yokufakelwa, njll, kusetshenziswa ukushisa kukagesi.

Isimiso sokusebenza:Imvamisa ephezulu yamanje igeleza iye kwikhoyili yokufudumeza (imvamisa eyenziwe ngeshubhu lekhopha elinsomi) elihlanganiswa libe yiringi noma okunye ukuma. Ngenxa yalokho, ugongolo oluqinile lukazibuthe olunoshintsho olusheshayo lwe-polarity lukhiqizwa kukhoyili, futhi izinto ezishisiwe njengensimbi zifakwa kukhoyili, ugongolo lukazibuthe luzodlula kuyo yonke into eshisayo, futhi i-eddy current enkulu izoba khona. okukhiqizwa ngaphakathi kwento evuthayo ngokuphambene nendawo yokushisa. Njengoba kukhona ukumelana entweni eshisayo, ukushisa okuningi kwe-Joule kukhiqizwa, okubangela ukushisa kwento ngokwayo kukhuphuke ngokushesha. Inhloso yokushisa zonke izinto zensimbi ifinyelelwa.
