Menene Na'urar bushewa?

Na'urar bushewa tana cire ruwa daga wani abu mai lalacewa don adana shi, tsawaita rayuwarsa da/ko sanya shi ya fi dacewa da sufuri.Masu bushewa masu daskarewa suna aiki ta daskarewa kayan, sannan rage matsa lamba da ƙara zafi don ƙyale daskararren ruwa a cikin kayan don canzawa kai tsaye zuwa tururi (sublimate).

Na'urar bushewa tana aiki a matakai uku:
1. Daskarewa
2. Bushewa na Farko (Sublimation)
3. Yin bushewa na biyu (Adsorption)

Daskarewa mai kyau na iya rage lokutan bushewa da kashi 30%.

Mataki na 1: Matakin Daskarewa

Wannan shine lokaci mafi mahimmanci.Masu bushewa suna amfani da hanyoyi daban-daban don daskare samfur.

Ana iya yin daskarewa a cikin injin daskarewa, wanka mai sanyi (firiza harsashi), ko a kan shiryayye a cikin injin daskarewa.

· Na'urar bushewa tana sanyaya kayan da ke ƙasa da maki uku don tabbatar da cewa sublimation, maimakon narkewa, zai faru.Wannan yana adana sigar zahirin kayan.

Na'urar bushewa mafi sauƙi daskare tana bushewa manyan lu'ulu'u na kankara, waɗanda ana iya yin su ta hanyar daskarewa a hankali ko annealing.Koyaya, tare da kayan ilimin halitta, lokacin da lu'ulu'u suka yi girma suna iya karya bangon tantanin halitta, kuma hakan yana haifar da daskarewa mara inganci.Don hana wannan, ana yin daskarewa da sauri.

· Don kayan da suka saba yin hazo, ana iya amfani da annealing.Wannan tsari ya ƙunshi daskarewa da sauri, sannan haɓaka yanayin samfurin don ba da damar lu'ulu'u suyi girma.

Mataki na 2: Bushewar Farko (Sublimation)
· Mataki na biyu shine bushewa na farko (sublimation), wanda ake saukar da matsi kuma a sanya zafi a cikin kayan don ruwa ya nutse.

Wurin daskare na bushewa yana saurin haɓakawa.Na'urar bushewa mai sanyi ta daskare tana ba da fili ga tururin ruwa don mannewa da ƙarfi.Har ila yau, na'urar na'urar tana kare famfo daga tururin ruwa.

Kimanin kashi 95% na ruwan da ke cikin kayan ana cire su a wannan lokaci.

· Bushewa na farko na iya zama aiki a hankali.Yawan zafi zai iya canza tsarin kayan.

Mataki na 3: bushewa na biyu (Adsorption)
Wannan lokaci na ƙarshe shine bushewa na biyu (adsorption), lokacin da ake cire ƙwayoyin ruwa masu ɗaure da ionically.
Ta hanyar haɓaka yanayin zafi sama da na farkon lokacin bushewa, haɗin gwiwa yana karye tsakanin kayan da kwayoyin ruwa.

Daskare busassun kayan yana riƙe da tsari mara kyau.

Bayan na'urar bushewa ta gama aikinta, za'a iya karye injin ɗin tare da iskar gas mara ƙarfi kafin a rufe kayan.

Yawancin kayan ana iya bushewa zuwa 1-5% saura danshi.

Daskare Matsalolin bushewa don Gujewa:
Dumama samfurin da yawan zafin jiki na iya haifar da narke baya ko rugujewar samfur

Yawan na'ura mai ɗaukar nauyi ya haifar da yawan tururi da ke bugun na'urar.
o Yawaita samar da tururi

o Wurin da ya yi yawa

o Karamin wurin dandali

o Rashin isasshen firiji

· Haɗawar tururi - ana samar da tururi a cikin sauri fiye da yadda zai iya shiga ta tashar jiragen ruwa, tashar jiragen ruwa tsakanin ɗakin samfurin da na'ura, yana haifar da karuwa a matsa lamba.
