Ubwino wa galasi lopaka thermos Kodi galasi lopaka thermos limapangidwa bwanji?

Galasi imagwiritsidwa ntchito kwambiri masiku ano ndipo nthawi zonse yakhala chinthu chomwe chikufunika kwambiri pamsika. Pogwiritsa ntchito njira zinazake zochizira, sitingathe kungoyang'ana kwambiri mawonekedwe a galasi, komanso kubwezera zofooka zake, zomwe sizikugwirizananso ndi mawonekedwe achilengedwe a galasi. Mwachitsanzo, galasi lopaka utoto silimangotenthetsa kutentha kokha, komanso zidutswa zake sizingaphulike ndikuvulaza anthu, zomwe ndi zotetezeka komanso zodalirika. Kenako, ife monga awogulitsa mabotolo a madziadzafotokoza ubwino wa galasi lamkati lama thermondi njira yopangira galasi.

二. Ubwino wagalasi lopaka la thermos

1. Ponena za chitetezo, zinthu zambiri zimachitapo kanthuzotengera zachitsulo monga chitsulo chosapanga dzimbiri pa kutentha kwambiri kuti chipange zinthu zovulaza thupi; Makamaka mankhwala achi China ochotsedwa, yesetsani kuti musathire supu ya mankhwalawo mu chidebe chachitsulo, chifukwa zinthu zothandiza zomwe zili mumadzi a mankhwalawo zimagwirizana ndi chitsulocho ndikuyambitsa zotsatira zoyipa.

2. Ponena za mtengo, poyerekeza ndi mtengo wa chitsulo chosapanga dzimbiri kapena zipangizo zina, mtengo wa galasi lophimba ndi wotsika kwambiri;

3. Ponena za mphamvu ya kutentha,choyikapo galasi chopanda vacuumali ndi zabwino kwambirikutchinjiriza kutentha mphamvu pakati pa ma liners osiyanasiyana ndipo imakhala ndi mtengo wokwera; Ichi ndichifukwa chake ma liners agalasi akhala akugwiritsidwa ntchito nthawi zonse m'malo otenthamabotolo amadzikunyumba;

4. Kuteteza chilengedwe, ukhondo ndi kuyeretsa kosavuta;

Kodi chidebe cha galasi cha mphika wa thermos chimapangidwa bwanji?

① Chokonzekera chopanda kanthu m'botolo. Galasi lomwe limagwiritsidwa ntchito pa thermos ndi la galasi la sodium calcium silicate lomwe limagwiritsidwa ntchito kwambiri. Tengani madzi agalasi otentha kwambiri opanda zodetsa ndikuwuzira mubotolo lamkati lagalasibotolo lopanda kanthu ndi lakunja lopanda kanthu lokhala ndi makulidwe a khoma la 1 ~ 2mm mu chikombole chachitsulo.

② Chikhodzodzo chopanda kanthu. Botolo lamkati limayikidwa mu botolo lakunja, pakamwa pa botolo limatsekedwa mu chimodzi, ndipo njira yolumikizira siliva ndi kutulutsa mpweya imayikidwa pansi pa botolo lakunja. Kapangidwe ka galasi kameneka kamatchedwa botolo lopanda kanthu. Pali mitundu itatu ya botolo lagalasi lopanda kanthu: njira yolumikizira pansi, njira yolumikizira phewa ndi njira yolumikizira m'chiuno. Njira yolumikizira pansi ndikudula pakamwa pa botolo lamkati lopanda kanthu ndi pansi pa botolo lakunja lopanda kanthu, kulowetsa botolo lamkati kuchokera pansi pa botolo lakunja ndikulikonza ndi asbestos plug insert pad, kenako kuzungulira ndi kutseka pansi pa botolo lakunja, kulumikiza njira yaying'ono yamchira, ndikusungunula kutseka pakamwa pa mabotolo awiriwa. Njira yolumikizira mapewa ndikudula botolo lamkati lopanda kanthu, kudula botolo lakunja lopanda kanthu, kulowetsa botolo lamkati kuchokera kumapeto kwa botolo lakunja ndikulikonza ndi asbestos plug insert pad, kuchepetsa botolo lakunja mu botolo la phewa, kusungunula ndi kutseka mabotolo awiri, ndikulumikiza chitoliro chaching'ono chamchira. Njira yotsekera botolo la m'chiuno ndiyo kudula botolo lamkati lopanda kanthu ndi botolo lakunja lopanda kanthu, kudula chiuno m'magawo awiri, kuyika botolo lamkati mu botolo lakunja, kulumikizanso chiuno ndikulumikiza chitoliro chaching'ono cha mchira.

③ Chokutidwa ndi siliva. Kuchuluka kwa yankho la siliva la ammonia ndi yankho la aldehyde monga chochepetsera kumathiridwa mu botolo lopanda kanthu kudzera mu katheta kakang'ono ka mchira kuti galasi lizigwira ntchito. Ma ayoni asiliva amachepetsedwa ndikuyikidwa pamwamba pa galasi kuti apange galasi lopyapyala ngati filimu yasiliva.

④ Vacuum. Lumikizani chitoliro chakumbuyo cha botolo lokhala ndi zigawo ziwiri lokhala ndi siliva ndi makina oyeretsera ndi kutentha kufika pa 300 ~ 400 ℃, kuti galasi litulutse mpweya wosiyanasiyana wothira ndi chinyezi chotsalira. Nthawi yomweyo, pampu yoyeretsera imagwiritsidwa ntchito kutulutsa mpweya. Pamene mlingo wa vacuum m'malo olumikizirana a botolo ufika pa 10-3 ~ 10-4mmhg, chitoliro chakumbuyo chimasungunuka.
