Inxalenye ephambili yebhotile ye-thermos sisinyi. Ukuvelisa izinyini zebhotile kufuna la manyathelo mane alandelayo: ① Ukulungiswa kwebhotile. Izinto zeglasi ezisetyenziswa kwiibhotile ze-thermos ziqhele ukusetyenziswa kwiglasi ye-soda-lime-silicate. Thatha ulwelo lweglasi yobushushu obuphezulu obufanayo kwaye obungenabumdaka, kwaye uyivuthele kwiglasi yangaphakathi yepreform kunye ne-preform yangaphandle enobunzima bodonga lwe-1 ukuya kwi-2 mm kwi-metal mold (jonga i-Glass Manufacturing). ② Yenza inyongo ingabi nanto. Ibhotile yangaphakathi ifakwe ngaphakathi kwibhotile yangaphandle, umlomo webhotile uvalwe kunye, kwaye ipleyiti yesilivere inikezelwa phantsi kwebhotile yangaphandle.Iinxalenye zebhotile zeThermos
I-conduit yokusebenza kwe-air extraction, esi sakhiwo seglasi sibizwa ngokuba yibhotile engenanto. Kukho iindlela ezintathu eziphambili zokwenza iibhotile zeglasi ezingenanto: indlela yokutywina esezantsi, indlela yokutywina emagxeni kunye nendlela yokutywina esinqeni. Indlela yokutywinwa komzobo ongezantsi kukusika i-preform yangaphakathi kunye nokusika umzantsi webhotile yangaphandle. Ibhotile yangaphakathi ifakwe ukusuka ngaphantsi kwebhotile yangaphandle kwaye ilungiswe ngeplagi ye-asbestos. Emva koko i-bottom yebhotile yangaphandle ijikelezwe kwaye ivalwe, kwaye ityhubhu encinci yomsila ixhunyiwe. Umlomo webhotile uyadityaniswa kwaye uvalwe. Indlela yokutywinwa kwamagxa kukunqumla i-preform yebhotile yangaphakathi, ukusika i-preform yebhotile yangaphandle, ukufaka ibhotile yangaphakathi ukusuka ekupheleni kwebhotile yangaphandle kwaye uyilungise ngeplagi ye-asbestos. Ibhotile yangaphandle iyancitshiswa ububanzi ukuze yenze igxalaba lebhotile kwaye imilomo yeebhotile ezimbini zixutywe kwaye zitywinwe, kwaye ityhubhu encinci yomsila ixhunyiwe. . Indlela yokutywina edibeneyo yokuqhawula isinqe kukusika i-preform yebhotile yangaphakathi, ukusika i-preform yebhotile yangaphandle kwaye usike isinqe sibe ngamacandelo amabini, ubeke ibhotile yangaphakathi kwibhotile yangaphandle, uphinde udibanise isinqe, kwaye udibanise ityhubhu encinci yomsila. ③Isilivere efakwe kwipleyiti. Isixa esithile sesilivere ye-ammonia yesisombululo esiyinkimbinkimbi kunye nesisombululo se-aldehyde njenge-arhente yokunciphisa igalelwa kwisandwich engenanto yebhotile ngokusebenzisa i-catheter yomsila omncinci ukwenza i-mirror mirror reaction, kwaye i-ion zesilivere ziyancitshiswa kwaye zifakwe kumphezulu weglasi ukuze zenze into encinci. ifilimu yesilivere yesipili. ④ Vacuum. Umbhobho womsila wesilivere-efakwe kwi-double-layer bottle engenanto idibene nenkqubo ye-vacuum kwaye ishushu kwi-300-400 ° C, ibangela ukuba iglasi ikhuphe iigesi ezahlukeneyo ze-adsorbed kunye nomswakama oseleyo. Kwangaxeshanye, sebenzisa impompo yokufunxa ukukhupha umoya. Xa i-vacuum degree kwi-interlayer space yebhotile ifikelela kwi-10-3 ~ 10-4mmHg, umbhobho womsila uyancibilika kwaye utywinwe.
