iyo vacuum flask inoshanda sei

Wakambozvibvunza here kuti zvinwiwa zvinopisa zvinogara zvichipisa sei mu thermos kwemaawa?Iyi blog post inoburitsa zvakavanzika kuseri kweiyo thermos 'yepamusoro insulation kuita uye kuongorora sainzi inonakidza kuseri kwekuita kwayo.Kubva pakuzvarwa kwavo kusvika pakuita basa ravo muhupenyu hwedu hwemazuva ese, ngatimbonyura zvakadzama kuti midziyo ine njere iyi inoshanda sei.

Chii chinonzi vacuum flask?
A vacuum flask, inowanzonziwo vacuum flask, igaba rine madziro maviri rakagadzirwa negirazi kana simbi isina simbi.Iwo mabhodhoro maviri anopatsanurwa nenzvimbo yevacuum, achigadzira nzvimbo yekutsvaira.Ichi chivakwa chinoderedza kutamisa kupisa, zvichiita kuti thermos ive yakanaka yekuchengeta zvinwiwa zvinopisa uye zvinotonhora patembiricha yaunoda kwenguva yakareba.

Insulation process:
Kuti tinzwisise kuti thermos inoshanda sei, isu tinofanirwa kuongorora mukati mezvinhu zvakakosha izvo zvinobatsira kune yayo insulating zvivakwa:

1. Chigaba chemukati nekunze:
Madziro emukati nekunze e thermos anowanzo kugadzirwa nesimbi isina tsvina, girazi kana plastiki.Simbi isina tsvina inopa yakanakisa insulating zvivakwa, nepo girazi rinopa kujeka kwakanyanya uye makemikari kuramba.Zvinhu izvi zvinoshanda sechivharo, kudzivirira kunze kwekupisa kusvika kune zviri mukati meflask.

2. Vacuum chisimbiso:
Vacuum seal inoumbwa pakati pemadziro emukati nekunze.Maitiro acho anosanganisira kubvisa mhepo mugomba, kusiya nzvimbo yekutsvaira ine mashoma egasi mamorekuru.Sezvo kupisa kufambiswa ne convection uye conduction kunoda svikiro semhepo, vacuum inotadzisa kutamiswa kwesimba rinopisa kubva kunharaunda yekunze.

3. Reflective coating:
Mamwe ma thermoses ane reflexive metallic coating mukati mekunze kwemadziro.Kupfeka uku kunoderedza kupisa kwemwaranzi, kutamisa kupisa kuburikidza nemagetsi emagetsi.Inobatsira kuchengetedza tembiricha yezviri mukati meflask nekuratidzira kumashure kwemwaranzi yekupisa yakaburitswa.

4. Chivharo:
Chivharo kana chivharo che thermos, chinowanzo gadzirwa nepurasitiki kana rabha, chinoita basa rakakosha kuchengetedza vacuum nekuderedza kupisa kwekushisa kuburikidza nekuvhura kuchengetedza vacuum.Iyo yekumisa zvakare inodzivirira kurasika uye kudonha, kuve nechokwadi chekuti insulation inoramba yakasimba.

Iyo Sayenzi Yekumashure Insulation:
Basa re thermos rinonyanya kuenderana nenzira nhatu dzekudzivirira kutamisa kupisa:

1. Kuitisa:
Kufambisa (conduction) ndiko kutamisa kupisa nekusangana kwakananga pakati pezvinhu.Mune thermos, iyo vacuum gap uye insulation inhibit conduction pakati pemadziro emukati nekunze, kudzivirira kunze kwekunze tembiricha kusakanganisa zviri mukati.

2. Convection:
Convection inoenderana nekufamba kwemvura kana gasi.Sezvo mukati nekunze madziro e thermos ari vacuum akaparadzaniswa, hapana mhepo kana mvura kufambisa convection, zvakanyanya kuderedza kupisa kurasikirwa kana kuwana kubva kunharaunda.

3. Mwaranzi:
Kupisa kunogona zvakare kutamiswa nemasaisai emagetsi anonzi radiation.Nepo chivharo chinopenya pamadziro emukati meflask chichideredza kupisa kwemwaranzi, vacuum pachayo inoita sechidziviso chakanakisa kurwisa iyi fomu yekupisa.

mukupedzisa:
Iyo thermos inyanzvi yeinjiniya, ichishandisa misimboti yekupisa kupisa kupa yakavimbika insulation.Nekubatanidza iyo insulating zvivakwa zvevacuum gap nezvinhu zvinoderedza conduction, convection uye radiation, maflask aya anovimbisa chinwiwa chako chaunofarira chinogara patembiricha yaunoda kwemaawa pakupera.Saka nguva inotevera yaunonakidzwa nekapu inopisa yekofi kana kuti inozorodza iced tii kubva muthermos, tarisa kune yakaoma kunzwisisa sainzi yekuichengeta sezvaunoda iwe.
