Mu kupanga mafakitale amakono ndi kafukufuku wa sayansi,MolecularDkusungunukaEzidachakhala chida chofunikira kwambiri m'mafakitale monga mankhwala abwino, mankhwala, ndi kukonza chakudya chifukwa cha mfundo zake zapadera zolekanitsa ndi ubwino wake waukadaulo.
MamolekyuluDkusungunukaNdi njira yolekanitsira thupi kutengera kusiyana kwa kayendedwe ka mamolekyulu. Poyerekeza ndi njira zachikhalidwe zoyeretsera, kusungunuka kwa mamolekyulu kumachitika pansi pa mikhalidwe yokwera ya vacuum, zomwe zimathandiza kuti mamolekyulu omwe ali mu chisakanizo chamadzimadzi alekanitsidwe bwino kutengera njira zawo zosiyana (mtunda wapakati womwe molekyulu imadutsa pakati pa kugundana kawiri). Chifukwa kusungunuka kwa mamolekyulu kumachitika kutentha kochepa, ndikoyenera kwambiri kulekanitsa zinthu zomwe zimakhudzidwa ndi kutentha monga mavitamini, zonunkhira, ndi mafuta ofunikira.
Mu zida zoyeretsera mamolekyulu, mtunda pakati pa malo otenthetsera (evaporator) ndi malo oundana (condenser) ndi waufupi kwambiri, nthawi zambiri umakhala pakati pa masentimita angapo mpaka masentimita angapo. Pamene chisakanizocho chikutenthedwa, mamolekyu a zigawo zosiyanasiyana amasanduka nthunzi m'magawo osiyanasiyana, kutengera njira zawo zapakati. Mamolekyu opepuka, okhala ndi njira zazitali zapakati, amatha kufika pa condenser ndikusonkhanitsidwa, zomwe zimawasiyanitsa bwino ndi zigawo zolemera.
Ukadaulo wothira mamolekyulu umagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana:
● Mankhwala Abwino: Pakupanga mankhwala abwino, kusungunuka kwa mamolekyulu kungagwiritsidwe ntchito kuyeretsa zinthu zomwe zimachitika ndikuchotsa zinthu zosagwiritsidwa ntchito komanso zinthu zina zomwe sizinachitike.
● Makampani Opanga Mankhwala: Amagwiritsidwa ntchito popangira zosakaniza za mankhwala zoyera kwambiri, makamaka zomwe zimakhudzidwa ndi kutentha kapena zovuta kuziyeretsa pogwiritsa ntchito njira zina.
● Makampani Ogulitsa Zakudya: Pochotsa zokometsera zachilengedwe, mafuta ofunikira, ndi mavitamini, kusungunuka kwa mamolekyulu kumathandiza kusunga zinthu zachilengedwe ndi ntchito ya zamoyo ya zinthuzo.
● Kupanga Zodzoladzola: Amagwiritsidwa ntchito popanga mafuta ofunikira apamwamba komanso zotulutsa zomera, kuonetsetsa kuti zinthu zomaliza zimakhala zotetezeka komanso zothandiza.
● Chitetezo cha Zachilengedwe: Pochiza madzi otayira ndi mpweya wotulutsa utsi m'mafakitale, kusungunuka kwa mamolekyulu kumathandiza kubwezeretsa mankhwala ofunika ndikuchepetsa kuipitsa chilengedwe.
Kutchuka kwa zida zoyeretsera mamolekyulu kungachitike chifukwa cha zabwino zotsatirazi zaukadaulo:
● Kutentha Kochepa Ntchito: Amaletsa kuwonongeka kwa zinthu zomwe zimakhudzidwa ndi kutentha, kusunga khalidwe la chinthucho komanso kukhazikika kwake.
● Kupatukana Kwambiri Mwachangu: Kutengera kusiyana kwa kayendedwe ka mamolekyu, zimathandiza kulekanitsa zinthu bwino komanso kukonza kuyera kwa zinthu.
● Kusinthasintha Kwamphamvu: Yoyenera kulekanitsa mitundu yosiyanasiyana ya zipangizo, kaya zogwiritsidwa ntchito m'magulu ang'onoang'ono kapena zazikulu.
● Kuteteza Zachilengedwe ndi Kugwiritsa Ntchito Mphamvu Mwanzeru: Ndi kutentha kochepa kogwira ntchito, mphamvu zomwe zimagwiritsidwa ntchito zimakhala zochepa, ndipo mpweya woipa umachepa.
● Zosavuta KulamuliraZipangizo zamakono zoyeretsera mamolekyulu zili ndi njira zamakono zowongolera kutentha, kuthamanga, ndi kayendedwe ka madzi zomwe zimathandiza kuti kutentha, kuthamanga, ndi kayendedwe ka madzi ziziyenda bwino.
Ngati muli ndi mafunso okhudza ukadaulo wa mamolekyulu kapena magawo ena ofanana, kapena ngati mukufuna kudziwa zambiri, chonde musazengereze kuyankha.CLumikizanani nafegulu la akatswiri. Tadzipereka kukupatsani ntchito yabwino kwambiri komansoKutembenukiraSmayankho.
