Ka hoʻohana o acetylene. acetylene kuʻihao

E maopopo kahi acetylene ua hoʻohana ', e mea pono e hoʻopaʻa haʻawina a me ka ike i ia mea. Kēia mea o ka colorless, flammable kinoea. Kona Nine Inch haʻilula - C ₂ H _2. Kinoea mai ka'ātoma nuipa a like ke 26,04. He O ka iki māmā ma mua o ke ea, a mai ka pungent ala. E hoomakaukau ai a me ka hoʻohana 'ana o ka acetylene ua lawe mai wale nō i loko o ka hanalima' ia. I ka waiwai a ua hoomakaukauia mai kalipuna carbide ma ka decomposing ke keʻena i loko o ka wai.

Pehea pilikia loa acetylene

Palapala noi acetylene kaupalena 'ia e kona kekahi waiwai. He kinoea ignites. Kēia ia lŘlŘ i ka wela o ka 335 ° C, a me ka läÿau, o ia me ka o oxygen, - i ka wela o ka 297 a hiki i 306 ° C, me ka lewa - i ka wela o ka mai 305 a hiki i 470 ° C.

It E e hoʻomaopopo i ka oaoieei-acetylene mea pahū. Keia i hanaia i ka wa:

1. e hoohaunaele ana i ka mahana i 450-500 ° C, a ma ka manaʻo koikoi o 150-200 kPa, ua like ia 1.5-2 me ka lewa.
2. A hui o acetylene a me ka oxygen ma ma ka lewa puʻe mea i pilikia ina mea iloko ona acetylene 2,3-93%. An Naita me ke'ākoʻakoʻa mai kiʻekiʻe wela, hamama lapalapa ahi a me nā hunaahi ahiahi.
3. Ma lalo o kēia mau ia keia, he läÿau, o ka ea Naita me ia lŘlŘ me acetylene, ina ia he 2,2-80,7% acetylene.
4. Inā ke kinoea ka lōʻihi ma ka hui 'ana me ke keleawe a me ke kala mea ke'ākoʻakoʻa atsetilenistoe ka pahū kala, a me ke keleawe. Kēia waiwai a pau ka noho pilikia loa. An Naita me ke'ākoʻakoʻa mai excessive hawewe a me ka hopena o ke ana wela ala. E hana ana i ke kinoea E e akahele.

hiʻona waiwai

Acetylene, ka mea, aole i hiki maopopo hoomaopopo ka waiwai a me ka noi o ka a, ka Naita me ke i ka ulia a me ka loa poino. Eia nō kekahi lāliʻi. Me ka Naita o kekahi kilogram o ka waiwai ua hookuu i loko o 2 manawa hou wela ikehu ma mua ma ka Naita o ka ia nui o TNT, a me ka hapalua kona manawa i oi aku mamua i Naita o kekahi kg o nitroglycerin.

noi acetylene

Acetylene - he combustible kinoea, a ua hoʻohana 'ia no ka kinoea kuʻihao. Pinepine ka mea, ua hoʻohana 'ia no ka lapalapa ana. It E e hoʻomaopopo i ka'ā mahana o ka läÿau, o ka o oxygen, a acetylene i hiki 3300 ° C. Aie i keia waiwai, i ka waiwai loa pinepine ia i loko o kuʻihao. Acetylene IeAUPIIe, IAa IO puku maoli kinoea , a LPG. Ka waiwai eaaaony i ka hana ana a me ka weld mea e like ai.

Kinoea lako wahi no kuʻihao, a ana hiki ke lawe mai ma ka acetylene mīkini hana wāwahie a mai nā paukūʻolokaʻa me ka acetylene. No ka pūnaewele o ka mea waiwai ua nui hoʻohana keʻokeʻo ipu. E like me ka rula, e lawe mai i ka palapala "Acetylene" ua hehi hoʻi i loko o ulaula ka inika. It O ke kumukuai o 'ana i kumumanaʻo ia he mea GOST 5457-75. E like me keia palapala ua hoʻohana 'ia no ka aaioee ke hooheheeia mea hoʻoheheʻe acetylene oaoieei-papa B a me ka waiwai i loko o ka gaseous palapala.

Acetylene kuʻihao: o kéu

E like me ke kinoea kuʻihaoʻano hana mea he mea. Naʻe, i ka wa a me ka mea ana koi ahonui a me ka attentiveness. No ka kuʻihao ōlelo maʻamau a kūikawā burners, 'ae' ia 0-5. Kona koho hilinaʻi nui ma luna o ka mānoanoa o ia mea i welded wahi. E noke i ka nui o ka puhiʻino, ka mea i oi aku i ka lehulehu.

acetylene kuʻihao ua lawe mai wale nō ma hope o ka ipu mai i ke kulana kupono, a like. Pela ka mea, Ua pono, e hoʻolohe i ke kihi pele helu a me ke kinoea kīʻamo, a ua hoʻonohonoho a puni i ka puhiʻino lima ma lalo o ka Nut. Oe E hoi ka huli a pau wepa.

Ke kuʻihao kaʻina

pono e lawe mai E ho ohana o ka acetylene ka wā kuʻihao akahele, a e like me kekahi mau rula. E hoʻomaka i ke kukui e e hoʻomaʻemaʻeʻana kinoea. Kēia E e hana a laila, a hiki i ke ala o ka acetylene. Mahope, ke kinoea ua ignited. Pela ka mea, Ua pono, e hoʻouka hou i oxygen a ka lapalapa i oi hale lio. Mai ka ia auoiaea kapa mokuna acetylene puʻe e ia mai ka 2 a hiki i 4 me ka lewa, a me ka oxygen ma - mai ka 2 me ka lewa.

No ka mea kuʻihao o ferrous ke hooheheeia pono he'ākilikai nā lapalapa. Ua Ua maopopo i ho'ākāka 'leialii, a conditionally hiki ke maheleia i ekolu vivid māhele: kāna mau' ōlelo - olinolino uliuli ano me ka omaomao iki tinge, hoihoi hou ia i ka lapalapa ahi - he haikea uliuli hue, lapalapa. Ka hope elua mau mea e hana.

Mua e hoʻomaka ana i ka hana, pono e ua holoiʻia nā māhele, a laila, hoʻomaʻa i kekahi i kekahi. I ka hana, i hana i ke puhiʻino ano no ka hema a me ka pololei. Ma ka hope neo he mea he kali hoʻi koʻu anuanu maila 'o ka weld. Ke fillerʻia nō kāu kolo ana ma luna o ka puhiʻino. I ka haʻalele hana maoli he elasticity a me ka ikaika o ka weld. Ma keia hihia, o ka lapalapa ahi ua olelo mai ka weld wahi. Ke fillerʻia E e pili ana i ka weld wai ma hope o ka hele a hiki i ka aʻe kulana o ka puhiʻino wale nō.

maluhia rula

Ka hoʻohanaʻana i acetylene me ka mākau a me ka hoao ana ua pāpā. Aia i kekahi mau rula e pono e hahai hana ana me ka mea i ka wa:

1. Ka maʻiʻo o ka acetylene i loko o ka lewa lumi pono e mau ua hoʻonānā. E hana i kēia, e hoʻohana i ka hana 'akomi manaʻo, a e hiki ke hai aku e pili ana i ka liki ole kinoea lehulehu. Kēia uku E ole e oi aku mamua o 0,46%.
2. Noi acetylene i loa okoa, akā loa pinepine ka mea, ua hoʻohana 'ia no ka kuʻihao. I ka hana ana me ka ipu piha i like keia kinoea, mālama nui e e hana. Ua Ua papaia e waiho i ka pahu kokoke i ka hamama lapalapa ahi a kokoke paio hahana maoli nō nenoai. Eia hou, ka mea, ua papaia e hana me nā paukūʻolokaʻa i ka mea i loko o ka papamoe kulana, a ina ka mea, i ole paʻa a me ka mea hemahema.
3. I ka hana ana me acetylene, ole-sparking hana, uila lako a pan, a kau iho Naita me-maopopo hoʻohana wale.
4. Inā he mea i liu mai i ka paukūʻolokaʻa o acetylene, ia mea pono e koke pani i ka nohona kiwikā 'auhau. Hiki nō ke hoʻohana 'ole-sparking kūikawā kī. Ho oholo kulu hiki wale nō ia i ka leo a me ka ala.

He aha ina ua he ahi

Kūpono 'ana o ke acetylene ke alakai i ka lono kaumaha hopena. He kinoea explodes, a lawe mai i ka ikaika luku. ina ke ahi, mai hemo mai He aha e hana ai?

1. Ina o ke ahi pono e koke wehe 'ia mai ka pilikia ciia a pau i nā ipu piha i acetylene. ʻO ka pahu i koe, e e mālama me me ka akaka ka wai a me ke kupaianaha hui. Pahu e hooluolu loa.
2. Inā ignited kinoea e hele mai ana mai loko mai o ka huewai, ia lakou e ike koke pani i ka ipu. E hana i kēia, oe e hoʻohana 'ole-sparking wrench. Ma hope iho o ia, pono e me ka 'auhau.
3. Inā he ikaika ke ahi pio ke ahi e halihaliia oia iwaho wale mai i ka mamao palekana. Ma ia he kulana home 'ole mea e hoʻohana i ke ahi extinguisher piha me ka haku mele i loaʻa ka phlegmatizing naikokene lehulehu o ka 70% ma ka buke, a me carbon dioxide i 75% ma ka buke, ke one, ka wai mokulele hēkī,'opihia naikokene, asbestos lole, a no laila, ma luna o.
