Ibicuruzwa bya molekuline structure
Kalisiyumu karbide (formula ya molekile: CaC2), ni ubwoko bwibikoresho byingenzi bya chimique biva mu gutunganya imiti ya hekeste. Mu 1892, H. Maysan (Igifaransa) na H. Wilson (Leta zunze ubumwe) icyarimwe bateje imbere uburyo bwo gukora kariside ya calcium ishingiye ku kugabanya itanura. Leta zunze ubumwe z’Amerika zageze ku musaruro w’inganda mu 1895. Umutungo wa kariside ya calcium ujyanye n’ubuziranenge bwayo. Ibicuruzwa byayo mu nganda ahanini bivanze na kariside ya calcium na oxyde ya calcium, kandi bikubiyemo urugero rwa sulfure, fosifore, azote n’ibindi byanduye. Hamwe nubwiyongere bwibintu byanduye, ibara ryerekana imvi, umukara kugeza umukara. Ingingo yo gushonga hamwe nu mashanyarazi byombi bigabanuka hamwe no kugabanuka kwera. Ubuziranenge bwibicuruzwa byinganda mubusanzwe ni 80% hamwe mp ni 1800 ~ 2000 ° C. Ku bushyuhe bwicyumba, ntabwo yifata numwuka, ariko irashobora kugira okiside hejuru ya 350 and, kandi ikagira reaction ya azote kuri 600 ~ 700 ℃ kugirango itange calcium cyanamide. Kalisiyumu karbide, iyo ihuye namazi cyangwa amavuta, itanga acetylene ikarekura ubushyuhe bwinshi. CaC2 + 2H2O─ → C2H2 + Ca (OH) 2 + 125185.32J, 1kg ya kariside nziza ya calcium irashobora gutanga 366 L ya acetylene 366l (15 ℃, 0.1MPa). Kubwibyo, kububiko bwayo: kariside ya calcium igomba kubikwa kure yamazi. Ubusanzwe ipakirwa mu cyuma gifunze, kandi rimwe na rimwe ikabikwa mu bubiko bwumye bwuzuyemo azote nibiba ngombwa.
Carbide ya calcium (CaC2) ifite impumuro imeze nka tungurusumu kandi ifata amazi kugirango ikore gaze ya acetylene hiyongereyeho calcium hydroxide nubushyuhe. Mu bihe byashize, yakoreshwaga mu matara y'abacukuzi kugira ngo ikomeze gutanga urumuri ruto rwa acetylene kugira ngo rutange urumuri mu birombe by'amakara.
Kalisiyumu karbide ikoreshwa nka desulfurizer, umwuma wibyuma, lisansi mugukora ibyuma, deoxidizer ikomeye kandi nkisoko ya gaze ya acetylene. Ikoreshwa nkibikoresho byo gutangiza gutegura calcium cyanamide, Ethylene, reberi ya chloroprene, aside acike, dicyandiamide na cyanide acetate. Ikoreshwa mu matara ya karbide, ibikinisho by'ibikinisho nka top-bang nini na bamboo. Ifitanye isano na calcium ya fosifike kandi ikoreshwa mukureremba, kwiyitirira ibimenyetso byo mu maziCalcium karbide ni karbide yingirakamaro cyane mu nganda kubera uruhare rwayo nkishingiro ryinganda za acetylene. Ahantu habuze peteroli, Kalisiyumu Carbideikoreshwa nkibikoresho byo gutangiza umusaruro wa acetylene (kg 1 ya karbide itanga ~ litiro 300 acetylene), nayo, ishobora gukoreshwa nkigice cyubaka imiti itandukanye (urugero nka vinyl acetate, acetaldehyde na acide acetike) ). Mu turere tumwe na tumwe, acetylene nayo ikoreshwa mu gukora vinyl chloride, ibikoresho fatizo byo gukora PVC.
Gukoresha bike cyane Kalisiyumu Carbide ifitanye isano n'inganda za ferilizers. Ifata na azote ikora calcium cyanamide, nicyo kintu gitangira kubyara cyanamide (CH2N2). Cyanamide nigicuruzwa gisanzwe cyubuhinzi gikoreshwa mugukangura amababi hakiri kare.
Kalisiyumu Carbide irashobora kandi gukoreshwa nkibikoresho bya desulfurizasi yo gukora ibyuma bya karubone nkeya. Nanone, ikoreshwa nkigikoresho cyo kugabanya ibyuma biva mumunyu wabo, urugero, kugabanya sulfide y'umuringa kugeza kumuringa. Umuriro. Byongeye kandi, igira uruhare mukugabanya umuringa sulfide kumuringa wumuringa.
Chemwin irashobora gutanga ibintu byinshi bya hydrocarbone hamwe nu muti wa chimique kubakiriya binganda.Mbere yibyo, nyamuneka soma amakuru y'ibanze akurikira yerekeye gukora ubucuruzi natwe:
1. Umutekano
Umutekano nicyo dushyira imbere. Usibye guha abakiriya amakuru ajyanye no gukoresha ibicuruzwa byacu neza kandi bitangiza ibidukikije, twiyemeje kandi ko umutekano w’abakozi n’aba rwiyemezamirimo wagabanuka kugeza ku gipimo cyiza kandi gishoboka. Kubwibyo, turasaba abakiriya kwemeza ko ibipimo bikwiye byo gupakurura no kubika ibicuruzwa byujujwe mbere yo gutanga (nyamuneka reba umugereka wa HSSE mumagambo rusange nuburyo bwo kugurisha hepfo). Impuguke zacu HSSE zirashobora gutanga ubuyobozi kuri aya mahame.
2. Uburyo bwo gutanga
Abakiriya barashobora gutumiza no gutanga ibicuruzwa biva muri chemwin, cyangwa barashobora kwakira ibicuruzwa biva muruganda rwacu rukora. Uburyo buboneka bwubwikorezi burimo amakamyo, gari ya moshi cyangwa ubwikorezi butandukanye (ibintu bitandukanye birakurikizwa).
Mugihe cyibisabwa abakiriya, turashobora kwerekana ibisabwa bya barge cyangwa tanker hanyuma tugashyiraho umutekano wihariye / gusuzuma ibipimo nibisabwa.
3. Umubare ntarengwa wateganijwe
Niba uguze ibicuruzwa kurubuga rwacu, umubare ntarengwa wateganijwe ni toni 30.
4. Kwishura
Uburyo busanzwe bwo kwishyura ni kugabanywa bitarenze iminsi 30 uhereye kuri fagitire.
5. Inyandiko zitangwa
Inyandiko zikurikira zitangwa na buri gutangwa:
· Umushinga w'itegeko, CMR Waybill cyangwa izindi nyandiko zijyanye no gutwara abantu
· Icyemezo cyo gusesengura cyangwa guhuza (niba bikenewe)
· Inyandiko zijyanye na HSSE zijyanye n'amabwiriza
· Inyandiko za gasutamo zijyanye n'amabwiriza (niba bikenewe)
