III. Cov ntaub ntawv thiab cov txheej txheem tsim khoom ntawm cov txheej txheej sab hauv

Cov txheej txheej sab hauv khob yog ib txheej tiv thaiv uas tiv thaiv sab hauv ntawm cov khob ntawv khov nab kuab. Cov hom ntaub sab hauv uas siv ntau yog raws li nram no.

A. Hom khoom siv rau txheej txheej ntawm cov khob ntawv, xws li polyester, polyethylene, thiab lwm yam

1. Polyethylene

Polyethylene siv dav hauv kev txheej txheej ntawm cov khob ntawv vim nws cov yam ntxwv zoo tiv taus dej thiab roj, nrog rau nws tus nqi qis. Cov no ua rau nws tsim nyog rau kev tsim cov khob ntawv ice cream loj.

2. Polyester

Cov txheej polyester tuaj yeem muab kev tiv thaiv ntau dua. Yog li, nws tuaj yeem tiv thaiv cov ntxhiab tsw, roj nkag mus, thiab cov pa oxygen nkag mus. Yog li ntawd, polyester feem ntau yog siv rau hauv cov khob ntawv zoo dua.

3. PLA (polylactic acid)

PLA muaj kev ua haujlwm tsis zoo hauv dej, tab sis nws cuam tshuam nrog kev tiv thaiv ib puag ncig thiab siv dav hauv qee lub khw muag khoom kim heev.

B. Qhia txog cov txheej txheem tsim khoom, xws li cov txheej txheem tshwj xeeb thiab kev vuam.

Cov txheej txheem tsim cov txheej txheej rau cov khob ntawv yog raws li nram no:

1. Cov txheej txheem tshwj xeeb

Hauv cov txheej txheem tsim cov khob ntawv, cov txheej txheej sab hauv yog siv dav kom ntseeg tau tias cov khob tsis muaj dej thiab tsis muaj roj. Txoj kev los xyuas kom meej tias cov txheej txheej tau faib thoob plaws hauv tag nrho lub khob yog siv cov thev naus laus zis txhaj tshuaj niaj hnub. Ua ntej, cov av noo uas tsim tau raug ntes thiab npaj, thiab tom qab ntawd txhaj rau hauv sab hauv ntawm lub khob ntawv.

2. Kev vuam

Qee zaum, cov txheej txheem tshwj xeeb tsis tsim nyog. Hauv qhov no, sab hauv ntawm lub khob ntawv tuaj yeem siv cov txheej txheem kaw cua sov (lossis vuam). Qhov no yog ib qho txheej txheem ntawm kev nias ntau txheej ntawm cov ntaub ntawv sib txawv ua ke, ua kom sab hauv thiab lub cev khob nruj nreem ua ke. Los ntawm kev muab ib txheej tiv thaiv txhim khu kev qha, cov txheej txheem no ua kom ntseeg tau tias lub khob ntawv ruaj khov rau qee qhov thiab yuav tsis xau.

Cov saum toj no yog kev qhia txog cov hom ntaub ntawv thiab cov txheej txheem tsim khoom rau kev txheej txheej ntawm cov khob ntawv. Cov ntaub ntawv xws lipolyethylene thiab polyester yog tsim rau ntau qib ntawm khob ntawvs. Thiab cov txheej txheem tshwj xeeb thiab cov txheej txheem tsim khoom vuam tuaj yeem ua kom zoo thiab ua tau zoo ntawm cov ntawv khob sab hauv.

IV. Cov yam ntxwv cuam tshuam rau kev xaiv cov txheej txheej sab hauv

A. Tej yam uas cuam tshuam rau ib puag ncig

Nrog kev txhim kho tas mus li ntawm kev paub txog ib puag ncig, cov txheej txheej ntawm cov khob ntawv feem ntau siv cov khoom siv rov ua dua tshiab. (Xws li PLA thiab ntawv ntoo pulp). Cov khoom siv ntawd tuaj yeem lwj tag nrho thiab muaj kev cuam tshuam tsawg dua rau ib puag ncig.

B. Cov yam ntxwv ua haujlwm yooj yim

Kev xaiv cov txheej txheej uas yooj yim tsim thiab ntim khoom tuaj yeem txhim kho kev tsim khoom zoo dua thiab txo cov nqi. Piv txwv li, kev siv thiab kev tsim cov txheej polyethylene yooj yim heev. Qhov ntawd tuaj yeem ua rau lawv tsim nyog rau kev tsim cov khob ntawv loj.

C. Cov yam ntxwv cuam tshuam

Qhov zoo nkauj, tiv taus qhov xau, thiab tiv taus cov dej khov yog txhua yam uas yuav tsum tau xav txog rau kev txheej txheej ntawm lub khob ntawv. Yuav kom tswj tau qhov kub thiab saj ntawm ice cream, tiv taus qhov xau thiab tiv taus icing yog qhov tsim nyog los muab kev noj mov zoo dua.

Yog li ntawd, thaum xaiv cov txheej txheej rau cov khob ntawv, nws yog qhov tsim nyog los ntsuas cov yam saum toj no kom txiav txim siab cov khoom siv txheej tsim nyog tshaj plaws.

V. Kev Txheeb Xyuas

Ntxiv rau kev xaiv cov txheej txheej sab hauv uas tsim nyog, kev ceev faj thaum lub sijhawm tsim khoom kuj tseem ceeb heev. Nov yog ob peb lub ntsiab lus tseem ceeb:

A. Khaws cov khoom siv raw

Cov khoom siv raw rau txheej txheej ntawm cov khob ntawv, suav nrog cov txheej txheej, khob ntawv, thiab lwm yam, yuav tsum tau khaws cia rau hauv qhov chaw qhuav, cua nkag, thiab tiv thaiv dej noo kom tiv thaiv dej noo thiab kuab paug, uas tuaj yeem cuam tshuam rau qhov zoo thiab lub neej ua haujlwm ntawm cov txheej txheej.

B. Kev kuaj xyuas nruj

Yuav tsum tau kuaj xyuas cov khoom siv raw thiab cov khoom tiav thaum lub sijhawm tsim khoom kom paub tseeb tias qhov zoo ntawm cov txheej txheej hauv khob ntawv ua tau raws li cov qauv.
