Nayitrojeni wamadzimadzi: Mpweya wa nayitrojeni mumadzi. Wosatentha, wopanda mtundu, wopanda fungo, wosapsa, wosapsa, kutentha kwambiri kwa cryogenic. Nayitrojeni imapanga mlengalenga wambiri (78.03% ndi voliyumu ndi 75.5% kulemera kwake).Nayitrojeni sagwira ntchito ndipo sathandizira kuyaka. Frostbite chifukwa kwambiri endothermic kukhudzana pa vaporization.
Nayitrogeni wamadzimadzi ndi gwero lozizira bwino. Chifukwa cha mawonekedwe ake apadera, nayitrogeni yamadzimadzi imaperekedwa pang'onopang'ono ndikuzindikiridwa ndi anthu. Zakhala zikugwiritsidwa ntchito mochulukirachulukira pakuweta ziweto, m'makampani azachipatala, m'makampani azakudya, komanso m'magawo ofufuza a cryogenic. Mu zamagetsi, zitsulo, mlengalenga, makina opanga makina ndi zina za ntchito zakhala zikukula ndikukula.
Maluso amadzimadzi a nayitrogeni cryogenic tizilombo toyambitsa matenda
Mfundo ya njira yosonkhanitsira nayitrogeni yamadzimadzi, yomwe imasonkhanitsa mitundu ya mabakiteriya pa -196 ℃, ndikusonkhanitsa tizilombo mogwira mtima pogwiritsa ntchito mwayi woletsa kagayidwe kake ka tizilombo toyambitsa matenda pansi -130 ℃. Macrofungi ndi gulu lofunika la bowa (bowa omwe amapanga matupi akuluakulu okhala ndi zipatso mu bowa, nthawi zambiri amatanthauza bowa kapena bowa m'njira yotakata). Mitundu yambiri imakhala ndi mtengo wokwera wa zakudya komanso mtengo wamankhwala, ndipo imakhala ndi chiyembekezo chogwiritsa ntchito bwino pakati pa mafangasi. Kuphatikiza apo, mafangasi ena akuluakulu amatha kusanthula mbewu zakufa, zomwe zimagwira ntchito yofunika kwambiri posunga kufalikira kwa zinthu zachilengedwe komanso kukhazikika kwachilengedwe, ndipo zitha kupangidwa ndikugwiritsidwa ntchito kumakampani opanga mapepala komanso kuyeretsa chilengedwe. Bowa zina zazikulu zimatha kuyambitsa matenda amitengo kapena kuwononga mitundu yosiyanasiyana yamitengo. Kupititsa patsogolo kumvetsetsa kwa bowa woyambitsa matendawa kumathandizira kupewa ndikuchotsa zovulaza. Kusonkhanitsa kwachitsanzo kwa macrofungi ndikofunika kwambiri pakukhala chete ndi kusonkhanitsa zamoyo za tizilombo tating'onoting'ono, kusonkhanitsa kosatha ndi kothandiza kwa majini, ndi kugawana zamoyo zosiyanasiyana m'malo osiyanasiyana.
Kupulumuka kwa chibadwa cha zamoyo zaulimi
Dziko la Shanghai laika ndalama zoposera 41 miliyoni kuti likhazikitse ndi kutumiza nkhokwe yatsatanetsatane yamitundu yazaulimi ku China. Makampani opanga mbewu, omwe ali ndi kuthekera kotsegulira msika wapadziko lonse lapansi, agwiritsa ntchito banki ya majini ngati gwero la zoweta, atero azaulimi. Shanghai Agricultural Biological gene Bank, yokhala ndi malo okwana masikweya mita 3,300, ipezeka ku Shanghai Academy of Agricultural Sciences. Idzasonkhanitsa mitundu isanu yazinthu zachilengedwe zaulimi kuphatikiza mbewu za mbewu, zida zopangira ma cell, maselo obereketsa a nyama, tizilombo tating'onoting'ono ndi zida zopangira majini.
Mankhwala ozizira
Kukula mwachangu kwamankhwala a cryogenic kwalimbikitsa kukula kwa mankhwala oyika mafupa, makamaka m'mafupa, ma cell a hematopoietic tsinde, khungu, cornea, zotupa zamkati zamkati, mitsempha yamagazi ndi ma valve, ndi zina zambiri. tsinde maselo. Mu kuzizira ndi kuzizira kwa zitsanzo zamoyo, panthawi ya kusintha kuchokera kumadzi kupita ku olimba, kutentha kwina kumatulutsidwa ndipo kutentha kwake kumakwera. Kuzizira kozizira popanda kuwongolera kuzizira kumabweretsa kufa kwa maselo opangidwa. Chinsinsi chothandizira kupulumuka kwa zitsanzo zowuma ndikuzindikira molondola gawo la kusintha kwa zitsanzo zamoyo ndikugwiritsa ntchito microcomputer kuziziritsa mayendedwe kuti muwonjezere kuchuluka kwa nayitrogeni wamadzimadzi panthawi yakusintha, kupondereza kukwera kwa kutentha. magawo kusintha zitsanzo ndi kupanga maselo kudutsa gawo kusintha mwakachetechete ndi mofulumira.
Mankhwala achipatala
Nayitrogeni wamadzimadzi ndi refrigerant yomwe imagwiritsidwa ntchito kwambiri mu cryosurgery. Ndi firiji yomwe idapangidwa mpaka pano, ndipo mukayibaya mu chipangizo chachipatala cha cryogenic, imakhala ngati scalpel, ndipo mutha kuchita opaleshoni iliyonse. Cryotherapy ndi chithandizo chomwe chimagwiritsa ntchito kutentha kwa cryogenic kuphwanya kapangidwe ka zilonda. Chifukwa cha kusintha kwakukulu kwa kutentha kwa selo, mapangidwe a kristalo mu kapangidwe pamwamba, kotero kuti kuchepa kwa madzi m'thupi, kuchepa, electrolytes ndi kusintha kwina, kuzizira kungapangitsenso kuti magazi aziyenda pang'onopang'ono, kuchepa kwa magazi kapena embolism. imfa ya cell hypoxia.
HL Cryogenic Equipment
HL Cryogenic Equipmentyomwe idakhazikitsidwa mu 1992 ndi mtundu womwe umagwirizana nawoHL Cryogenic Equipment Company Cryogenic Equipment Co., Ltd. HL Cryogenic Equipment yadzipereka kupanga ndi kupanga High Vacuum Insulated Cryogenic Piping System ndi Zida Zothandizira Zothandizira kukwaniritsa zosowa zosiyanasiyana za makasitomala. The Vacuum Insulated Pipe ndi Flexible Hose amapangidwa mu vacuum yayikulu komanso yosanjikiza yamitundu ingapo ya zida zapadera zotchingidwa, ndipo amadutsa munjira zingapo zamankhwala okhwima kwambiri komanso ma vacuum apamwamba, omwe amagwiritsidwa ntchito kusamutsa mpweya wamadzimadzi, nayitrogeni wamadzimadzi. , argon yamadzimadzi, haidrojeni yamadzimadzi, helium yamadzimadzi, mpweya wa ethylene LEG ndi mpweya wachilengedwe wa liquefied LNG.
Mndandanda wazinthu za Vacuum Valve, Vacuum Pipe, Vacuum Hose ndi Phase Separator mu HL Cryogenic Equipment Company, yomwe idadutsa mndandanda wamankhwala okhwima kwambiri, amagwiritsidwa ntchito ponyamula mpweya wamadzimadzi, nayitrogeni wamadzi, argon wamadzimadzi, hydrogen yamadzimadzi, yamadzimadzi. helium, LEG ndi LNG, ndipo zinthuzi zimatumizidwa ku zida za cryogenic (mwachitsanzo, akasinja a cryogenic ndi ma flasks a dewar etc.) m'mafakitale amagetsi, superconductor, tchipisi, MBE, pharmacy, biobank / cellbank, chakudya & chakumwa, msonkhano wodzichitira okha, ndi sayansi. kafukufuku etc.
