N-Butane yoyera kwambiri: Zipangizo zamtengo wapatali za mankhwala, zomwe zimathandiza bwino zinthu zosiyanasiyana ndi zinthu zochepa zodetsedwa, khalidwe lokhazikika, magwiridwe antchito abwino kwambiri oyaka, kuwongolera khalidwe lonse, komanso kupereka malo amodzi.

Chiyambi cha zinthu zazikulu

n-Butane (CAS: 106-97-8) ndi chinthu chopangidwa ndi alkane chemical chowongoka. Ndi mpweya wopanda mtundu, wowonekera, komanso woyaka pansi pa mikhalidwe yabwinobwino, wosavuta kusungunuka, wopanda fungo, komanso wokhala ndi makhalidwe okhazikika komanso achilengedwe. Ndi chinthu choyambira mumakampani opanga mankhwala chokhala ndi mitundu iwiri ya mafuta komanso chopangidwa ndi zinthu zina. Chogulitsachi chimakonzedwa kudzera mu njira yowongolera molondola, kuwongolera mosamala zizindikiro zodetsa monga kuchuluka kwa sulfure, kuchuluka kwa madzi, methanol, dimethyl ether, ndi zina zotero. Zinthu zazikulu ndi ≥99.5% (mafotokozedwe apamwamba a kuyera akhoza kusinthidwa). Chimayaka kwathunthu popanda utsi wakuda, kapangidwe kake ndi kofatsa komanso kowongoleredwa, ndipo ndi chosavuta kusungira ndi kunyamula, choyenera njira zosiyanasiyana zopangira mafakitale. Chimakwaniritsa miyezo yadziko lonse komanso miyezo yapadziko lonse lapansi yazinthu zopangira mankhwala, ndipo chimagwiritsidwa ntchito kwambiri mumafuta amafakitale, kupanga mankhwala, kuzizira ndi kuwotcha thovu, ma aerosol ndi madera ena. Ndi chinthu chapamwamba kwambiri cha mankhwala chomwe chimagwira ntchito bwino komanso chokhazikika.

Ubwino waukulu wa zinthu

Kuyera kwambiri ndi zinyalala zochepa, kuwongolera bwino khalidwe: Zomwe zili mkati mwake nthawi zambiri zimakhala ≥99.5%, ndipo 99.9% zomwe zili mkati mwake zimakhala zoyera kwambiri zimatha kusinthidwa; zizindikiro zazikulu za zinyalala monga kuchuluka kwa sulfure, kuchuluka kwa madzi, ndi zotsalira za nthunzi zimakhala zochepa kwambiri kuposa miyezo yamakampani, palibe fungo, palibe zotsalira zovulaza, zomwe zimaonetsetsa kuti njira yopangira zinthu kuchokera ku gwero ikhale yokhazikika.

Kugwira ntchito kokhazikika komanso kusinthasintha kwamphamvu: Ili ndi mphamvu zokhazikika za mankhwala, yosavuta kusungunuka, kusungidwa ndi kunyamulidwa pansi pa kutentha ndi kupanikizika kwabwinobwino, mphamvu yoyaka kwambiri komanso kuyaka kwathunthu, palibe utsi wakuda, palibe coking; monga zopangira zopangira, yankho lake ndi lofatsa, lopanda zotsatira zoyipa zambiri, loyenera njira zosiyanasiyana zamafakitale monga kukonzanso, catalysis, polymerization, ndi zina zotero, popanda kukhudza mtundu wa zinthu zomwe zili pansi pa madzi.

Zogwiritsidwa ntchito zosiyanasiyana komanso zosiyanasiyana: Zili ndi mphamvu ya mafuta komanso kapangidwe ka mankhwala. Zingagwiritsidwe ntchito mwachindunji ngati mafuta oyera, komanso ngati chothandizira kukonza zinthu zosiyanasiyana zamakemikolo, kukwaniritsa zosowa za mafakitale osiyanasiyana nthawi imodzi ndikuwonjezera kugwiritsa ntchito bwino zinthu zopangira.

Kusungirako ndi mayendedwe osavuta, kupereka kosinthasintha: Kumathandizira njira zosiyanasiyana zosungiramo ndi mayendedwe monga madzi osungunuka (thanki yaying'ono / thanki yayikulu) ndi mayendedwe a magalimoto a thanki, oyenera kugwiritsidwa ntchito poyesa magulu ang'onoang'ono komanso kupereka kwakukulu kokhazikika; ndi mapangidwe angapo a nyumba zosungiramo katundu mdziko lonselo, malonda odutsa malire amatha kufananizidwa ndi mayankho apadziko lonse lapansi monga mayendedwe apanyanja ndi mayendedwe apamtunda, kuonetsetsa kuti kutumiza kutumizidwa nthawi yake.

Kutsatira miyezo ndi magwiridwe antchito okwera mtengo: Chogulitsachi chikukwaniritsa miyezo yadziko lonse ya mankhwala opangira zinthu zopangira ndi zoyezera kutumiza kunja ndi kutumiza kunja, ndi kutsata kwathunthu ndi malipoti athunthu oyesera, omwe angagwiritsidwe ntchito mwachindunji pabizinesi yotumiza kunja; njira yokonzanso ndi yokhwima, kupanga kwakukulu kumachepetsa mtengo wa unit, ndipo palibe kusintha kwina kofunikira kuti muwonjezere, kuthandiza makasitomala kuchepetsa ndalama ndikuwonjezera magwiridwe antchito.

Ntchito zazikulu m'magawo angapo

Chifukwa chodalira mphamvu zake zabwino zakuthupi ndi zamakemikolo komanso ubwino wake woyeretsa kwambiri, n-Butane yakhala yofunika kwambiri.zipangizo zoyambira zopangira mankhwala, mafuta a mafakitale, firiji ndi thovu, ndi zochitika zogwiritsira ntchito zomwe zimakhudza unyolo wonse wa mafakitale akumtunda ndi akumunsi:

Mafuta a mafakitale: Pambuyo pothira madzi, amagwiritsidwa ntchito ngati gasi woyera, mafuta otenthetsera mafakitale, mafuta a barbecue akunja, okhala ndi ma calories ambiri, kuyaka koyera, malo osungiramo ndi mayendedwe abwino, oyenera mabanja, mafakitale, chakudya ndi zina zotero; ingagwiritsidwenso ntchito ngati chowonjezera cha mafuta a injini yoyaka mkati kuti iwonjezere mphamvu yoyaka.

Mankhwala opangidwa mwapadera: Monga chinthu choyambira cha alkane, chimatha kukonza zinthu za mankhwala monga butadiene, isobutane, acetic acid, acrylic acid, maleic anhydride kudzera mu catalysis, cracking ndi njira zina, ndipo ndi chinthu chofunikira kwambiri cha rabara yopangidwa, mapulasitiki, zokutira, ndi zinthu zina zopangira mankhwala.

Malo osungiramo zinthu mufiriji ndi thovu: Monga chosungiramo zinthu mufiriji ndi thovu, chimatha kusintha ma freon ena, oyenera zida zosungiramo zinthu monga mafiriji ndi mafiriji, komanso chimagwiritsidwanso ntchito popanga thovu pogwiritsa ntchito zinthu za rabara ndi pulasitiki monga polyurethane ndi polystyrene, ndi thovu lofanana komanso magwiridwe antchito okhazikika a zinthu zomalizidwa.

Ntchito zina zamafakitale: Monga chotenthetsera mpweya, chimagwiritsidwa ntchito popanga zinthu za tsiku ndi tsiku za mankhwala ndi mankhwala; monga chogwirizira cha labotale, chimagwiritsidwa ntchito pofufuza mankhwala ndi kafukufuku wa sayansi; chingagwiritsidwenso ntchito ngati chowonjezera cha madzi ophwanyika mafuta kuti chiwongolere bwino mafuta ndi mpweya.
