Imvelaphi
Ukuphumeza ukupholisa ngesifunxa kwishishini lokubhaka kuye kwavela njengempendulo kwimfuno yeebhaka-bhaka yokunciphisa ixesha ukusuka kwinyathelo lokwandisa izithako ngokupakisha imveliso.
Yintoni Ukupholisa iVacuum?
Ukupholisa ivacuum yeyona ndlela ikhawulezayo nesebenza ngakumbi kuneatmospheri yemveli okanye ukupholisa kwe-ambient.Bubuchwephesha obutsha obusekwe ekwehliseni umahluko phakathi koxinzelelo lweatmospheri kunye noxinzelelo lomphunga wamanzi kwimveliso.
Ngokusebenzisa impompo, inkqubo yokupholisa ivacuum isusa umoya owomileyo nofumileyo kwindawo yokupholisa ukuze yenze ivacuum.
Oku kukhawulezisa i-vaporization yokufuma okukhululekile kwimveliso.
Iibhakabhaka ezinesantya esiphezulu ziyaxhamla kobu buchwephesha ngokunciphisa amaxesha omjikelo kunye nokusetyenziswa ngokufanelekileyo kwendawo yomgangatho wemveliso.
Ingaba isebenza kanjani
Kule nkqubo, izonka eziphuma kwi-oven kumaqondo obushushu asondele kwi-205 ° F (96 ° C) zibekwe okanye zihanjiswe ngokuthe ngqo kwigumbi lokucoca.Ilinganiswe ngokusekwe kwiimfuno zokusetyenzwa, amaqhekeza ngomzuzu avelisiweyo, kunye nokusetyenziswa komgangatho.Emva kokuba imveliso ilayishiwe, igumbi le-vacuum liyavalwa ukuze lithintele ukutshintshwa kwegesi.
Impompo yokufunxa iqala ukusebenza ngokususa umoya kwigumbi lokupholisa, ngoko ke yehlisa uxinzelelo lomoya (atmospheric) kwigumbi.Ivacuum eyenziwe ngaphakathi kwesixhobo (inxalenye okanye iyonke) yehlisa indawo yokubilisa yamanzi kwimveliso.Emva koko, ukufuma okukhoyo kwimveliso kuqala ukuphuma ngokukhawuleza kwaye ngokuthe ngcembe.Inkqubo yokubilisa ifuna ubushushu obufihliweyo bomphunga, oburhoxiswa nge-crumb yemveliso.Oku kubangela ukuhla kweqondo lokushisa kwaye kuvumela ukuba isonka siphole.
Njengoko inkqubo yokupholisa iqhubeka, impompo yokufunxa ikhupha umphunga wamanzi ngecondenser eqokelela ukufuma ize ibuse kwindawo eyahlukileyo.
Izinto eziluncedo zokupholisa ivacuum
Amaxesha amafutshane okupholisa (ukupholisa ukusuka kwi-212 ° F / 100 ° C ukuya kwi-86 ° F / 30 ° C kunokufezekiswa kwi-3 kuphela kwi-6 min).
Umngcipheko ophantsi wongcoliseko lokungunda emva kokubhaka.
Imveliso inokupholiswa kwisixhobo se-20 m2 endaweni ye-250 m2 yokupholisa inqaba.
Inkangeleko ye-crust ephezulu kunye ne-symmetry engcono njengoko ukuncipha kwemveliso kuncitshiswa kakhulu.
Imveliso ihlala i-crusty ukunciphisa ithuba lokuwa ngexesha lokusika.
Ukupholisa ivacuum sele kukho amashumi eminyaka, kodwa kunamhlanje kuphela apho itekhnoloji ifikelele kwinqanaba lokuvuthwa okuphezulu ngokwaneleyo ukufumana ukwamkelwa ngokubanzi ngakumbi kwizicelo zokubhaka.
