Kodi pali kusiyana kotani pakati pa ufa wouma ndi ufa wa mankhwala ouma?

Pa ntchito ya tsiku ndi tsiku ya osakaniza ufa, ogwiritsa ntchito angakumane ndi funso lovuta ili:

N’chifukwa chiyani ufa wina umasakanikirana bwino komanso moyenera, pomwe wina umafuna kuwongolera kutentha ndi chinyezi? Izi nthawi zambiri zimachokera ku lingaliro lalikulu lomwe limasokonezeka mosavuta—“ufa wouma” poyerekeza ndi “ufa wa mankhwala ouma.”Ngakhale kuti zonsezi zimawoneka ngati ufa wouma, malinga ndi sayansi ya zinthu, zimasiyana kwambiri.

I. Matanthauzo

"Ufa wouma" ndi mawu ambiri otanthauza zipangizo zopangira mafakitale. M'magawo a mafakitale ndi ukadaulo wa ufa, amatanthauza zinthu zonse zomwe zilipo mu mawonekedwe a tinthu tolimba touma.

Zipangizo zotere zimapezeka kwambiri m'mafakitale opanga tsiku ndi tsiku, monga ufa ndi mkaka wa ufa m'makampani opanga chakudya, ufa wa mankhwala, komanso utoto ndi zodzaza m'makampani opanga mankhwala.

Ponena za osakaniza ufa, cholinga chachikulu pokonza "ufa wouma" uwu nthawi zambiri chimakhala kukwaniritsakusakaniza kofanana kwa thupiAkatswiri osakaniza zinthu amayang'ana kwambiri zinthu monga kufalikira kwa tinthu tating'onoting'ono, mawonekedwe a tinthu tating'onoting'ono, kuchuluka kwa tinthu tating'onoting'ono, komanso kuyenda bwino kuti atsimikizire kuti zinthu zosiyanasiyana sizimasiyana pambuyo posakaniza.

Mosiyana ndi zimenezi, “ufa wouma wa mankhwala” ndi lingaliro lodziwika bwino komanso losavuta kulimvetsa bwino lomwe limagwira ntchito bwino komanso momwe mankhwalawo amachitira zinthu.

Mu nkhani za uinjiniya ndi chitetezo cha moto, mawuwa amatanthauza gulu la ufa wopangidwa ndi akatswiri opangidwa pogwiritsa ntchito mankhwala apadera. Sizinthu zakuthupi zokha, komanso zinthu zothandiza zomwe zili ndi ntchito zinazake za mankhwala.

Ntchito yawo yodziwika bwino ndi yozimitsira moto. Mwachitsanzo, ufa wa mankhwala owuma wa ABC umapangidwa makamaka ndi ammonium phosphate, pomwe ufa wa mankhwala owuma wa BC umapangidwa makamaka ndi sodium bicarbonate. Ufa uwu umapangidwa kuti uchite zinthu zinazake (monga kukhudzana ndi moto) kuti uchepetse kuyaka.

II. Kusiyana kwa Kupanga Zosakaniza

Pa ufa wamba wouma, ntchito yayikulu ya chosakanizira ndi kukonzakhalidwe losakaniza thupi.

Ogwiritsa ntchito ayenera kusintha liwiro la kusakaniza ndi nthawi yake malinga ndi zinthu monga ngodya yopumulira ndi kuchuluka kwa zinthu, kuti apewe kugawikana pambuyo posakaniza. Cholinga chake ndikupeza "mofanana" weniweni.

Njira yonseyi ndi yosinthasintha pang'ono. Ngakhale kuti ukhondo wa chilengedwe, kutentha, ndi chinyezi ziyenera kuganiziridwabe, nthawi zambiri palibe chiopsezo chachikulu cha mankhwala chomwe chingakhalepo.

Komabe, pa ufa wouma wa mankhwala, mavuto osakaniza amasandukakukhazikika kwa mankhwala ndi kulondola kwa kapangidwe kake.

Pokonza ufa woterewu, cholinga chake si kungosakaniza kokha, komanso:

● kupewa zotsatira za mankhwala zosayembekezereka

● kuonetsetsa kuti pali ma ratio olondola a kapangidwe kake

● kusunga bata la magwiridwe antchito

Mwachitsanzo, popanga ufa wozimitsa moto, chiŵerengero cha ammonium phosphate ndi zowonjezera chiyenera kukhala cholondola kwambiri. Ngakhale kusiyana pang'ono pa kapangidwe kake kungachepetse kwambiri magwiridwe antchito ozimitsa moto kapena kupangitsa kuti mankhwalawa asagwire ntchito.

Kuphatikiza apo, ufa uwu nthawi zambiri umakhala wofanana ndi wa hygroscopic ndipo ukhoza kukhala ndi zinthu zina zowononga kapena zokwiyitsa. Chifukwa chake, makina osakaniza angafunike kukhala ndi:

● makina oteteza fumbi komanso oteteza kutayikira kwa madzi amphamvu kwambiri

● makina oteteza mpweya wopanda mphamvu (ngati pakufunika)

● machitidwe owongolera kutentha kuti achepetse kutentha komwe kumachitika chifukwa cha kukangana panthawi yosakaniza

Njira izi zimathandiza kupewa kuphwanyika, kuwonongeka, kapena dzimbiri la zida panthawi yokonza.

III. Madera Ogwiritsira Ntchito

Kusiyana kumeneku kumaonekera makamaka mu ntchito zozimitsa moto.

Mu miyezo yapadziko lonse lapansi monga machitidwe ogawa a NFPA, "ufa wouma" nthawi zambiri umagwiritsidwa ntchito kutanthauza zozimitsira moto zapadera zachitsulo za Class D, pomwe "ufa wa mankhwala ouma" nthawi zambiri umatanthauza zozimitsira moto zambiri za Class A, B, ndi C.

Komabe, m'mabizinesi ndi m'masiku onse, chifukwa ufa wa mankhwala ouma a ABC ndiwo amagwiritsidwa ntchito kwambiri, mawu awiriwa nthawi zambiri amagwiritsidwa ntchito mosinthana.

Komabe, mosasamala kanthu za kusiyana kwa mawu, mfundo yaikulu imakhalabe yofanana:
Ufa wouma wa mankhwala ndi chinthu chogwiritsidwa ntchito popanga mankhwala enaake, pomwe ufa wamba wouma ndi chinthu chogwiritsidwa ntchito popanga zinthu zosakaniza.
