Iinkcukacha zenqaku
I-EJER yamkela i-molekyuli sieve emoyeni owomileyo, inkqubo yonke ilawulwa yi-microcomputer, xa ukufuma kuphezulu, Iya kuqala ukufunxa ukufuma, xa ukufuma kufikelela kwixabiso elibekiweyo, kuya kuyeka ukufunxa, kwaye emva koko ikhuphe amanzi ngaphandle kwekhabhinethi ngokufudumeza, ngokuphindaphindiweyo ngolawulo oluzenzekelayo. Eyona nto isebenzayo kunye nengqongileyo yokufuma i-desiccant yimolekyuli sieve, Imolekyuli sisixhobo se-microporous crystal esenziwe yi-silicon kunye ne-aluminium oxide. Ukugcina umnatha wokukhutshwa kwekristale ukuba ube yi-zero, ii-athom ezine-cation zibekwe kwisakhiwo sekristale. Kwaye i-cation esetyenziswe kwezikristalu zokwenziwa zihlala ziyisodium. Okwangoku, kukho iintlobo ezimbini zeemolekyuli zisetyenziswa ngokubanzi kwishishini lebhokisi eyomileyo: Iklasi A kunye neKlasi X. Iimvume zeemolekyuli zihlanganisiwe, zimile kwaye zisebenze phantsi kweenkqubo zemveliso elawulwa ngokungqongqo. Inkqubo yonke elawulwayo yokuhlanganiswa inokuqinisekisa ukungaguquguquki kobungakanani obunamacala amathathu. 3A molecular sieve pore ubungakanani be-3 angstroms, 4A molecular sieve pore ubungakanani be-4 angstroms; Ubungakanani be-molekyuli ye-13X yi-8.5 angstroms. Umgaqo wokusebenza wemolecular sieve: Iimolekyuli zeemolekyuli adsorb iimolekyuli kumphezulu wekristale ngamandla omtsalane. Kuba i-95% indawo yomphezulu we-molekyuli iphakathi kwe-vulture, kufuneka ikhangele iimolekyuli ezikufutshane ngobukhulu obahlukeneyo. Kuphela iimolekyuli ezincinci ezinokungena kumphezulu we-adsorption ye-molekyuli sieve ngokuvula kwekristale. Esi siganeko sokukhetha sibizwa ngokuba siziphumo zemolekyuli. Umthamo we-molekyuli sieve adsorption kunye nokuxinana kwentlawulo (i-polarity) kunxulumene namamolekyuli adsorbed. Iimolekyuli zeemolekyuli zinokuphinda zahlule ukuba zeziphi iimolekyuli ezixubeneyo ezinokuthi zisebenze kwaye zimisele ukuya kuthi ga kwinqanaba lokuxinana kwentlawulo iimolekyuli eziza kufakwa kwikristale. Iimolekyuli zamanzi zincinci ngakumbi (2. Ii-angstroms ezingama-6), ezikwiimolekyuli ze-polar kakhulu (ubuninzi obuqinisekileyo kunye nobubi be-electron), kwaye zihlaziya ibethwe ngeemolekyuli, Nokuba phantsi kwemeko yokufuma ephantsi kakhulu, xa iimolekyuli zamanzi ziye zafakwa, ziya kulungiswa ngokuqinileyo kwikristale. Isixhobo sokufunxa ukufuma esingqongileyo sixhotyiswe ngeemolekyuli. Xa ifunxa, isilawuli se-alloy yememori sikwimeko yokuxinana, kwaye intwasahlobo ikwimeko yesivumelwano, ekwenzeni uqhagamshelwano lwe-valve lungaphandle, oku kugquma umoya ongaphandle ukusuka ngaphakathi kwebhokisi yomoya owomileyo ukufezekisa injongo yokuphelisa; kwaye emva kokufuma kwemolekyuli kufunxwe ngaphakathi kwebhokisi eyomileyo kwaye igcwaliswe, Inkqubo iya kulawula ngokuzenzekelayo isixhobo se-alloy yememori ukuyinciphisa ukuze i-valve ifike kwindawo yangaphakathi ye-baffle. Okwangoku, ngenxa yokunciphisa i-alloy yememori, intwasahlobo yolulekile kwaye ivalve iyakhutshwa ngaphandle kwe-baffle, ukwenzela ukufuma kwi-seve yemolekyuli ikhutshwe ngaphandle. Emva kokuba inkqubo yokuphelisa igqityiwe, inkqubo ngokuzenzekelayo ilawula kwaye iphinde i-alloy yememori kunye nentwasahlobo, ukuqala kwakhona imeko yokufunxa….
