Kung'anima-mfundo

Kung'anima - yomweyo kuyaka kwa chisakanizo cha mpweya ndi nthuzi zinthu flammable, limodzi ndi lalifupi yowala chowala. kuyaka khola ndi ichi. Flashpoint - osachepera kutentha zinthu Zachepetsedwa, imene padziko awo anapanga awiri lonyezimira ngati nthethe, malawi kapena incandescent thupi.

Luso kung'anima pa kutentha wotsika ndi madzimadzi zokhudza gulu flammable. Zolemba malire flashpoint zinthu zoterozo mu crucibles chatsekedwa ndi + 61 ° C, lotseguka - + 66 ° C. Ena zinthu akhoza azinyadira zokha, kufika lililonse kwa kutentha awo poyatsira.

Khama la kuthamanga nthunzi ya zimalimbikitsa n'zotheka madzi aliyense flammable. Izo kumawonjezera mogwirizana ndi kuonjezera kutentha kwa nkhaniyo. Kamodzi mfundo kung'anima umalandira yovuta (pazipita) index, ndipo akhala kukhalabe kuyaka.

Komabe, isanayambike mgwirizano "nthunzi - madzi" mufunikira nthawi, imene ndi njila kwa mlingo wa mapangidwe nthunzi. kuyaka Khola chingapezeke, kufika ena (kwa aliyense thunthu) poyatsira kutentha, chifukwa kutentha kuyaka nthawi zonse kuposa mfundo kung'anima.

Direct kusintha kutentha pa zimene nkhani kung'anima ali ndi mavuto ena. Choncho, mfundo kung'anima akuti ndi kutentha kwa zimene chotengera makoma, imene kung'anima izi zimawonedwa. Zimatengera mwachindunji pa zinthu kutentha zochitika mu kutentha kuwombola chotengera ntchito zake othandizira pa chilengedwe, buku la madzi mu chotengera.

Indicators kulola mayesero kuwerengera kololeka zoyendera ndi kusunga kutentha zinthu flammable. Anayeza kutentha kung'anima mu crucibles chatsekedwa, kawirikawiri Pensky-Martens. COC ndi chinaneneratu experimentally.

zakumwa oopsa kwambiri, makamaka angathe mwamsangamsanga kutentha m'munsimu -18 ° C mu crucibles chatsekedwa pansipa - 13 ° C - lotseguka. Kupitiriza ankaganiza zakumwa woopsawo amene akhoza kudzauka pa kutentha + 23 ° C mu crucibles chatsekedwa kwa + 27 ° C lotseguka. Indicators kutentha zakumwa woopsawo kwa + 60 ° C Ponena mu crucibles chatsekedwa kwa + 66 ° C Ponena - pamene lotseguka.

Kung'anima kutentha kusiyana, ndi poyatsira ndi kuyaka zimasiyanasiyana kwambiri, ndipo munthu aliyense mankhwala. Pophulikira ya dizilo Mwachitsanzo - osapitirira + 70 ° C. kuyaka kutentha kwake - + 1100 ° C. Flashpoint - kuchokera + 100 ° kwa + 119 ° C. Koma mafuta kung'anima kutentha, chifukwa osakhalitsa kwambiri, ndi + 40 ° C, ndi zina zochepa. poyatsira ake kutentha - + 300 ° C. Indicators petulo, zambiri zowombetsa mkota. Iwo ayenera kuonedwa sing'anga, chifukwa pali mitundu yosiyanasiyana ya mafuta (msewu (chilimwe, yozizira), mpweya) ndi makhalidwe zayamba osiyana ndi moyenera, kutentha zosiyanasiyana kung'anima poyatsira kuyaka.

Kuyaka - ndondomeko limodzi ndi kumasula wambirimbiri kutentha ndi umuna khalidwe la kuunika (luminescence), lingathe pa kutentha ena lililonse chinthu ndi mpweya mwayi kapena wothandizila ena (sulfure, bromine nthunzi ndi zina zotero.).

The owopsa ndi mabomba, yodziwika ndi yomweyo mankhwala anachita kumasula mphamvu kwambiri, ndi kuthandiza ntchito makina. Moto kuphulika akhoza kufalitsa kwa mamita 3,000 pa mphindi. Kuyaka wa osakaniza Pa mtengo wotchedwa detonation. Kodi chotsatira cha detonation mafunde mantha zambiri kuwononga kwambiri ndi ngozi.
