Raws li ib qho ntawm cov khoom siv dav siv niaj hnub no, ntau qhov kev lag luam muaj qee qhov kev xav tau rau cov lus qhia tshwj xeeb thiab zoo ntawm aluminium-yas npog. Lub sealing kev ua tau zoo ntawm aluminium-yas npog kuj yog ib qho tseem ceeb rau kev ntsuam xyuas lawv qhov zoo. Yog li ntawd, kev txhim kho kev sib khi ua haujlwm ntawm aluminium-yas npog kuj yog ib qho teeb meem uas ntau lub tuam txhab yuav tsum tau daws.
Txawm hais tias cov roj hmab ntuj, ua ib qho tseem ceeb ntawm cov kaus mom yas, muaj kev ua tau zoo, nws tseem muaj qee yam tsis muaj roj hmab xws li cov protein, acetone extract, noo noo, tshauv, thiab lwm yam. Yog li ntawd, ntau yam khoom ntawm lub kaus mom yas tsim. los ntawm cov khoom siv roj hmab ntuj no yuav tsis tas ua kom tau raws li qhov yuav tsum tau ua ntawm sealing ntim hauv kev lag luam kws tshuaj. Qhov tsis ua pa ntawm cov kaus mom impermeability thiab kev laus ruaj ntseg tsis zoo rau ntim ntim hauv kev lag luam kws tshuaj, uas tuaj yeem ua rau muaj kev nqus dej thiab ua kom tsis zoo ntawm qee cov dej rhiab heev thaum lub sijhawm khaws cia.
Txhawm rau daws qhov teeb meem no, cov chaw muag tshuaj thaum ntxov tau txais txoj hauv kev tsis qhib lub kaus mom txhuas, tom qab ntawd dov lub kaus mom thiab siv cov txheej txheem paraffin rau sab nraud. Txawm li cas los xij, txoj kev no yog qhov nyuaj heev thiab siv zog ua haujlwm, thiab nws kuj cuam tshuam rau cov tsos ntawm cov khoom ntim sab nraud. Qee lub chaw muag tshuaj kuj tseem siv cov txheej txheem ntawm polyester zaj duab xis rau sab nraud ntawm aluminium-yas npog, uas ua rau cov txheej txheem ntim khoom tsis yooj yim thiab tsis tuaj yeem tsim tawm ntawm ib kab sib dhos, ua rau muaj kev tsis yooj yim rau tag nrho cov txheej txheem tsim khoom.
Lwm qhov tseem ceeb yog khi lub raj mis cap. Muab lub raj mis uas tau ntim cov kua thiab capped rau hauv lub tais qis, thiab muab tso rau ntawm V-shaped txhawb nqa. Tuav lub raj mis kom nruj nrog ib txhais tes thiab rub tus tuav rov qab thiab downwards nrog rau lwm tes. Lub sijhawm no, tuav lub raj mis thiab nqa lub tais rau saum. Tom qab lub txhuas-yas cap thiab capping lub taub hau raug kaw, peb qhov txuas txuas txuas txuas capping hniav tig ob peb zaug ua ntej zawm lub raj mis cap. Nws yog tsim nyog rau lub cev muaj zog ua hauj lwm clockwise. Thaum kawg, thawb tus kov rau pem hauv ntej kom rov qab lub capped aluminium-yas cap rau nws qhov chaw qub nrog rau lub tais. Tag nrho cov txheej txheem kev ua haujlwm tiav, thiab cov haujlwm saum toj no tuaj yeem rov ua dua rau txhua lub raj mis cap dov yav tom ntej.
