Ukupheka point: iimpawu

Yethumba - into leyo uphawu naziphi na izinto ezimanzi. Kuyabonakala ukuba kulo lonke isisombululo akhiwa maqampu umphunga. Kufuneka kuqatshelwe ukuba abilayo liyasetyenziswa kuphela kwiqondo elithile, ngokuxhomekeke kuhlobo kweziyobisi. Esi salathisi yi luphawu ebalulekileyo. Ingasetyenziswa ukuba ukwahlulwa iikhompawundi ulwelo, kwakunye ukujonga zimsulwa.

Esi salathisi ezahlukeneyo izinto ezahlukeneyo. Ngenxa yoko, iqondo lobushushu oyile injini ifikelela iqondo 300-490 ° C, yaye amanzi oko 100 ° C. Le ubungakanani ebonakalayo kuxhomekeke eziliqela parameters, kuquka iimeko abilayo kunye nokwakhiwa kwento itshiswa.

Kufuneka ke ukuba abilayo uneempawu ezithile. Ngoko ke, lo engamanzi ingcinezelo umphezulu Umphunga wadala oluthi luqokelelane kunokuba kancinci phambi kumphezulu free. Xa sithetha ngalo phakathi kokusingqongileyo, oko kube shushu ngakumbi kakhulu kwi kwethumba. Oku kucacisa lo mkhuba "nobushushu", apho ulwelo akuthethi loo nto, kodwa uphawuleka aphezulu obushushu yokusebenza.

Kufuneka kuqatshelwe ukuba ubushushu abilayo ixhomekeke ubushushu eyodwa ekufuneka ukuxakeka ngababini kweziyobisi hayi ulwelo. Kulo mzekelo, i mercury akusoloko kusenzeka ukuba ndibhaptize ngokupheleleyo, ngoko kufuneka ithathele ingqalelo ulungiso ithermometer. eli xabiso yahlukile ulwelo ezahlukeneyo. I-avareji kucingwa ukuba utshintsho womoya ngu malunga 26 mm kukhokelela ekubeni ubushushu abilayo batshintshwa yi isidanga mnye.

Njani le salathisi kunceda ukufumanisa ukusulungeka kwimixube kunye nezisombululo? ulwelo eyohlobo luphawulwa abilayo kuyo rhoqo. lutshintsho - ngumqondiso oqinisekileyo lobukho ubumdaka ukuba zingahlukaniswa kwinkqubo neyanamhlanje, kwakunye nokusebenzisa izixhobo ezikhethekileyo - dephlegmators.

Kubalulekile ukuphawula ukuba udibaniso lwe ngezinto ezahlukeneyo zisetyenziswa ngokukodwa kwezinye iimeko. Oku kunika nkcukacha ulwelo. Umzekelo, ethylene ecocekileyo ethers amathumba ku 197 ° C kunye abilayo ubushushu nokubanda ngandlel ezincinane - malunga ne-110 ° C.

Emini yolwelo umphunga kwenzeka ngexesha xa ubushushu abilayo engqinelanayo sifikelelwe. Xa lo mphunga befumile ngaphezu kwamanzi ulwelo inani elifanayo kunye noxinzelelo lwangaphandle, nto leyo ekhokelela ukuba ukuyilwa amaqamza phezu mqulu.

Kufuneka ke ukuba abilayo kuthatha indawo ikwiqondo lobushushu enye, kodwa kusenokwenzeka ukuba sigcine utshintsho engqinelanayo ukuncitshiswa okanye ukwanda yengcinezelo lwangaphandle.

Oku kuchaza isenzeko xa belungiselela ukutya ezintabeni ixesha elide njengoko noxinzelelo omalunga 60 kPa amanzi amathumba esele 85 ° C. Ngenxa yesi sizathu, izidlo zilungiselelwa ngendlela cooker xi kakhulu ngokukhawuleza ngenxa yokuba oku kwandisa xi, kwaye oku kukhokelela ekwandeni kwamanani kwamaqondo elibilayo kulwelo olo.

Kufuneka kuqatshelwe ukuba indlela ukubila yi kweentsholongwane luqhelekileyo emzimbeni. Ngaphandle kwale nkqubo, akunakwenzeka ukulungisa nayiphi na ukutya. Kubalulekile kwakhona ukuba ulwelo lwe petroleum ukuvelisa izinto lokuqalisa uhlambulukile.
