Ko te whakamahi o te acetylene. fehokotaki'anga acetylene

Hei te mārama te wahi whakamahia acetylene te, ko reira e tika ana ki te ako me te matau he aha te mea te reira. Ko tēnei rauemi ko te hau koretae, he pūkākā. Ko tōna tātai matū - C ₂ H _2. Gas he papatipu ngota rite ki te 26,04. Ko ia he bit māmā ake i te hau, me te kua he kakara titohea. Te whakarite me te whakamahi o te acetylene kawea i roto i anake i roto i te taiao ahumahi. rite te taonga kei te i konupūmā carbide mā te decomposing wāhanga i roto i te wai.

Kia pehea te kino acetylene

acetylene Taupānga iti e ona āhuatanga faahiahia. tahuna ana tēnei hau. puta tenei i te pāmahana o te 335 ° C, me te ranunga ona ki te hāora, - i te pāmahana o te 297 ki te 306 ° C, ki te rangi - i te pāmahana o i 305 ki te 470 ° C.

Me kï reira e he taikaha te acetylene hangarau. I tupu tenei ka:

1. te whakatairanga i te pāmahana ki te 450-500 ° C me i te pēhanga o te 150-200 kPa, rite ki te 1.5-2 atmospheres.
2. Ko hoki te ranunga o te acetylene me te hāora i te pēhanga kōhauhau kino ki te kei reira acetylene 2,3-93%. Ka taea e tētahi pahūtanga puta i te wera nui, tuwhera mura me koraahi noa.
3. Raro i ngā āhuatanga ōrite reira he he ranunga o te rangi, me te pahūtanga acetylene ki te kei reira 2,2-80,7% acetylene.
4. Ki te he roa te hau i roto i te whakapā ki te parahi hiriwa ranei ahanoa kia puta atsetilenistoe te hiriwa taikaha parahi ranei. Tenei taonga ko te tino mōrearea. Ka taea e tētahi pahūtanga puta i te ru nui rite ki te hua o te pāmahana whakatika ranei. Mahi hau kia āta.

āhuatanga taonga

Acetylene, e kore e matau tino āhuatanga, me te tono o nei, te pahūtanga taea meinga he aituā me te kino kino. Here te tahi mau kōrero. Ki te tukua te pahūtanga o tetahi kirokaramu o te taonga i roto i te 2 nga wa atu pūngao wera atu i pahūtanga o te rahinga taua o TNT me ngā wā i te hawhe nui atu i pahūtanga o tetahi kg o nitroglycerin.

tono acetylene

Acetylene - he hau combustible, e whakamahia nei mō te hau fehokotaki'anga. E mea pinepine te whakamahia reira mo te tapahi mura. Me kï reira e kia tae te pāmahana ngingiha o te ranunga o te hāora, me te acetylene 3300 ° C. Nā ki tenei taonga, te taonga tino pinepine whakamahia i roto i te fehokotaki'anga. Acetylene te tikanga whakakapi hau māori , me te LPG. Ko te taonga whakarato te mahi me te Weld kounga.

Ka taea te kawea teihana Gas supply mō fehokotaki'anga me te whakairo i roto i te taha o te generator acetylene ranei i ipurau ki acetylene. Hoki te rokiroki o te taonga kei te tikanga e whakamahia ana ipu ma. Ka rite ki te tikanga, tapaea ana e ratou te tuhituhinga "Acetylene" takatakahia i roto i te waituhi whero. He mea utu te tuhituhi e reira he GOST 5457-75. E ai ki tenei tuhinga e whakamahia mō te tukanga konganuku rewa acetylene B kōeke hangarau te taonga i roto i te puka haurehu waihā ranei.

fehokotaki'anga Acetylene: taki

E ai ki te tikanga hau fehokotaki'anga ko tino ohie. Heoi, titau manawanui me te aro, ka pā ana ki te mea. tikanga hoki fehokotaki'anga whakamahi muratahi motuhake, tapaina 0-5. Tei Ko tōna kōwhiringa i runga i te āhua o matotoru kua paiherea wāhanga. Kia mōhio e te nui te pūwera, te nui te utu.

kawea fehokotaki'anga acetylene te i muri anake kua ki te kia tirohia, ka whakaritea te taputapu. Ko te kupu he mea e tika ana ki te aro ki te tau rere matamata me te pupuha hau, whakaritea nei a tawhio noa te ringa pūwera raro i te nati. kia tirohia hoki e koe hiri e katoa.

Ko te tukanga fehokotaki'anga

Me kawea Whakamahi o acetylene ina kakano ia i roto i āta, me te rite ki etahi tikanga. Hei tīmata kia te rama, hei pure hau. kia meatia tenei ra ano ka, tae noa ki te haunga o te acetylene. I muri iho, mura te hau te. Ko te kupu he mea e tika ana ki te tāpiri hāora noa riro te mura atu eu. Mai i te kōwae putanga taputapu kia pēhanga acetylene i 2 ki te 4 atmospheres, me he hāora - i 2 atmospheres.

Hoki te fehokotaki'anga o konganuku ferrous titau te mura kūpapa. Kua āta tāutuhia te reira i te karauna me te herenga e taea te wehea e toru nga wahi oraora: matua - tae puru kanapa ki te urukehu puwhero, whakahokia te mura - he hue puru koma, mura. Kei te mahi i te wāhi e rua whakamutunga.

I mua i te tīmata te mahi, me horoia nga wahi katoa, a ka whakarite ki tahi i te tahi. I roto i te mahi, mahi hoki te pūwera tikanga mo te maui, me te tika. I roto i te take whakamutunga i reira ko te tautauā puhoi o te Weld. Ko te rauemi filler tikanga neke i runga i te umu. A, no te mahue faarahi tikanga elasticity me te kaha o te Weld. I roto i tenei take, whakahaua te mura te i te rohe Weld. kia tono te rauemi filler ki te poka wai Weld i muri noa i te nekehanga ki te tūranga i muri o te pūwera.

ture haumaru

rāhuitia te whakamahi o acetylene waho nga pūkenga me wheako te. He maha ngā ture e me aru ka mahi ki te rauemi:

1. Me aroturuki tonu te ihirangi o te acetylene i roto i te rangi ruma. Ki te mahi i tenei, te whakamahi i te whakaaro aunoa motuhake, e e taea ki te whakamōhio e pā ana ki te kukū hau i te taikaha. e kore e tenei auau e neke atu i te 0,46%.
2. He tino rerekē Applications acetylene, engari tino maha te whakamahia reira mo kakano ia. A, no te mahi ki te ipu ki tonu ki rite tenei hau, kia hei whakararu tūpato. Kei te riria te reira ki te waiho i te ipu e tata ana te flame tuwhera tata pūnaha whakawera ranei. I tua atu, kua riria reira ki te mahi ki te ipurau e te hunga i roto i te tūnga whakapae, a ki te kahore e ratou pūmau me he hapa.
3. A, no te mahi ki acetylene, whakamahi anake taputapu sparking-kore, taputapu hiko, me te rama pahūtanga-tohu.
4. Ki te reira te mea he turuturu i te rango o te acetylene, he mea e tika ana ki te kati hohoro te kaha takirere. Ka taea e koe te whakamahi i sparking-kore kī motuhake. Ka taea e anake whakatau leakage kia te tangi kakara ranei.

He aha te ki te reira ko te ahi

whakamahi hē o te acetylene taea arahi ki nunu'a fakamamahi. Tenei pahū te hau, me te hopoi mai i te whakangaromanga kaha. Aha ki te mahi, ki te wawahi i te ahi i roto i?

1. I roto i te take o te ahi me nekehia tonu i te rohe ati nga oko katoa ki tonu i te acetylene. kia puritia hauhautanga ki te wai mania he pūhui motuhake ranei aua ipu e toe,. kia whakamatao ipu tino.
2. Ki te mura hau e tae mai i roto o te pounamu, kia kati tonu te reira i te ipu. Ki te mahi i tenei, kia koutou te whakamahi i wāwāhi kore-sparking. I muri i taua, me kia hauhautanga te aravihi.
3. Ki te kia kawea te ahi ahi whakanoatanga kaha i roto i anake i te tawhiti haumaru. I roto i te āhuatanga i taua, ko te ki te whakamahi i te whakapoko ahi ki tonu ki te hanganga kei roto phlegmatizing hauota kukū o 70% i te rōrahi, me te hauhā 75% i te rōrahi, onepu, jet wai, hauota kōpeke, kakahu papa kiripaka, me te pera i runga i.
