IV. Kev Cuam Tshuam Ib Puag Ncig ntawm Cov Khob Kas Fes
Cov khob ntawv khov nab kuab yog ib hom khob ntawv pov tseg uas siv ntau hauv lub neej txhua hnub. Kev nrov npe thiab kev txhim kho ntawm cov tswv yim tiv thaiv ib puag ncig tseem niaj hnub nce ntxiv. Tib neeg tsis txaus siab rau cov khob ntawv khov nab kuab ib txwm muaj lawm. Lawv cov kev xav tau rau kev siv tshuab tiv thaiv ib puag ncig tab tom nruj heev. Yog li, nws yog ib qho tseem ceeb heev uas yuav tsum kawm thiab tshawb nrhiav qhov cuam tshuam rau ib puag ncig ntawm cov khob ntawv khov nab kuab.
Cov thev naus laus zis tiv thaiv ib puag ncig rau cov khob ntawv khov nab kuab tau maj mam siv. Qhov no feem ntau yog vim muaj ntau yam teeb meem ib puag ncig uas cov khob ntawv khov nab kuab ib txwm muaj. Cov khob ntawv khov nab kuab ib txwm yog ua los ntawm cov yas lossis cov ntaub ntawv ntawv. Thiab lawv feem ntau siv ua cov khoom noj ntim. Txawm li cas los xij, kev siv mus sij hawm ntev tuaj yeem ua rau muaj teeb meem ib puag ncig hauv kev tsim khoom, kev siv, thiab kev pov tseg cov khob. (Xws li cov khib nyiab pov tseg, CO2 thiab lwm yam pa roj av, thiab kev ua qias tuaj ib puag ncig.)
Peb siv tau cov thev naus laus zis uas tsis ua rau ib puag ncig puas tsuaj los tsim cov khob ntawv ice cream. Thiab cov teeb meem ib puag ncig tuaj yeem txhim kho los ntawm cov hauv qab no.
1. Siv cov khoom siv uas lwj tau
Kev siv cov khoom siv PE/PLA uas lwj tau tuaj yeem lwj mus ua carbon dioxide thiab dej hauv av. Lawv muaj kev cuam tshuam tsawg heev rau ib puag ncig thiab ua raws li cov cai ntawm ib puag ncig.
2. Kev txuag hluav taws xob thiab kev txo qis pa phem
Cov chaw tsim khoom tuaj yeem siv cov thev naus laus zis txuag hluav taws xob thiab txo cov pa phem. Qhov ntawd suav nrog cov khoom siv tsim khoom siab heev thiab cov khoom siv cua sov. Lawv tuaj yeem ua kom zoo dua cov txheej txheem luam ntawv thiab tsim khoom. Qhov ntawd tuaj yeem txo kev siv hluav taws xob, cov pa roj av uas ua rau lub ntiaj teb sov, thiab pab txo cov pa phem ib puag ncig.
3. Kev siv dej dua tshiab
Cov thev naus laus zis siv dej rov qab tuaj yeem txo qhov kev pov tseg dej hauv cov txheej txheem tsim khoom. Yog li ntawd nws tuaj yeem pab txo qhov ua rau muaj kuab paug rau ib puag ncig.
4. Kev siv cov khoom pov tseg
Los ntawm kev siv cov thev naus laus zis siv cov peev txheej, cov ntawv pov tseg thiab cov yas pov tseg tuaj yeem rov ua dua tshiab. Nws tseem tuaj yeem txo qhov ua rau muaj kuab paug rau ib puag ncig thiab txhim kho kev siv cov peev txheej kom zoo.
Cov thev naus laus zis uas tsis ua rau ib puag ncig puas tsuaj ntawm cov khob ntawv ice cream tau coj ntau yam txiaj ntsig. Ua ntej, nws txo cov khoom pov tseg hauv cov txheej txheem tsim khoom, txuag hluav taws xob. Thiab nws pab txhim kho kev siv cov peev txheej kom zoo. Qhov thib ob, nws txo cov pa phem ib puag ncig los ntawm kev tsim khoom. Thiab nws pab tiv thaiv ib puag ncig thiab tswj kev noj qab haus huv ntawm tib neeg. Tsis tas li ntawd, kev siv cov thev naus laus zis no kuj tseem tuaj yeem txhim kho lub koob npe thiab tus nqi ntawm lub tuam txhab. Yog li, nws tuaj yeem tsim kom muaj kev lag luam ruaj khov thiab zoo rau ib puag ncig.
Tib lub sijhawm, kev siv cov thev naus laus zis tiv thaiv ib puag ncig no kuj tau ua rau muaj kev pab loj rau cov lag luam thiab cov neeg siv khoom. Rau cov lag luam, kev siv cov thev naus laus zis no tuaj yeem txhim kho lawv lub koob npe nrov thiab tus nqi lag luam. Yog li, nws tuaj yeem ua rau lawv qhov kev sib tw zoo dua. Thiab qhov no kuj tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub luag haujlwm niaj hnub ntawm cov tuam txhab. Rau cov neeg siv khoom, cov khob dej khov nab kuab zoo li no tuaj yeem lwj zoo tom qab siv. lawv ua rau muaj kuab paug me ntsis rau ib puag ncig. Thiab tom qab ntawd, nws tuaj yeem ua rau cov neeg siv khoom lub neej zoo dua thiab noj qab haus huv.
