Txoj Cai NtawmYas qhwv
Yas qhwv ncua kev noj zaub mov tsis zoo thiab khaws cia nws cov tshiab los ntawm kev cais cov huab cua, txo cov dej noo evaporation, thiab thaiv cov kab mob sab nraud. Nws lub luag haujlwm tseem ceeb suav nrog:
1. Kev cais cov pa oxygen: tiv thaiv cov pa oxygen los ntawm kev sib cuag nrog cov zaub mov, ua rau cov tshuaj tiv thaiv oxidation qeeb thiab tiv thaiv cov khoom noj los ntawm kev lwj, discoloring, los yog tsim cov ntxhiab tsw.
2. Moisturizing: Txo cov dej noo, ua kom cov zaub mov noo, thiab tiv thaiv kom qhuav.
3. cais cov kab mob: tiv thaiv cov kab mob sab nraud thiab cov plua plav nkag mus rau hauv cov zaub mov, txo qhov kev pheej hmoo ntawm kev lwj.
4. Sealing: xauv rau hauv cov khoom noj muaj ntxhiab thiab tiv thaiv nws los ntawm kev sib xyaw nrog lwm cov khoom noj.
Feem ntau sivYas qhwvKhoom siv
1. Polyethylene (PE):
Nta: Tsis yog - lom, tsis muaj ntxhiab, muaj kev nyab xeeb heev, thiab qhov kub thiab txias - tiv taus ntawm -60℃thiab 110℃.
Daim ntawv thov: Haum rau lub tub yees thiab luv luv -lub sij hawm khaws cia. Tsis pom zoo rau siv nyob rau hauv siab - qhov kub thiab txias (xws li microwave cua sov).
2. Polyvinyl Chloride (PVC):
Nta: Cov pob tshab siab, zoo yoog raws, thiab muaj zog adhesion, tab sis tej zaum yuav muaj cov yas yas (xaiv cov zaub mov- qib, tsis yog- cov khoom muaj kuab lom).
Daim ntaub ntawv: Siv dav hauv ntim cov khoom tshiab, txiv hmab txiv ntoo thiab zaub, tab sis tsis tuaj yeem tiv tauj ncaj qha nrog cov khoom noj muaj roj ntau lossis ua kom sov ntawm qhov kub thiab txias.
3. Polyvinylidene Chloride (PVDC):
Nta: Cov khoom muaj zog muaj zog, tiv thaiv cov pa oxygen thiab noo noo nkag mus, thiab ua haujlwm kub zoo.
Daim ntaub ntawv: Feem ntau siv los khaws cov khoom noj zoo (xws li cov nqaij thiab cov khoom siv mis nyuj), tab sis kim dua.
Yuav xaiv li casYas qhwv
1. Kev Nyab Xeeb Khoom Noj:
Paub meej tias cov khoom yog khoom noj khoom haus - qib cling zaj duab xis thiab tsis txhob muaj teeb meem plasticizers (xws li phthalates).
Cov khoom siv PE feem ntau muaj kev nyab xeeb dua thiab haum rau kev siv hauv tsev txhua hnub.
2. Daim Ntawv Thov:
Cov Khoom Noj Txias Txias: Cov khoom siv PE lossis PVC yog qhov tsim nyog, vim tias lawv muaj kev yooj yim thiab adhesion.
Cov khoom muaj kev tiv thaiv siab yuav tsum muaj: PVDC cov khoom siv tuaj yeem siv tau los ua kom lub neej ntev dua.
Microwave cua sov: Siv cov ntaub qhwv yas cim "siab kub resistant", xws li PE khoom haum rau microwave ncu, thiab tsis txhob siv PVC.
3. Them Nyiaj Rau Cov Ntawv Sau:
Tshawb xyuas lub ntim rau daim ntawv pov thawj kev tiv thaiv zaub mov (xws li FDA daim ntawv pov thawj lossis lwm cov cim kev nyab xeeb zaub mov).
Xaiv qhov tsim nyog ntsuas qhov ntsuas kub raws li qhov ntsuas kub.
Lub Ntsiab Tseem Ceeb NtawmYas qhwv
1. Kev txuag zaub mov:
Qhwv cov zaub mov tshiab, zaub mov siav, txiv hmab txiv ntoo, zaub, qhob cij, thiab lwm yam kom ncua sij hawm cia khoom noj.
2. Kev tiv thaiv lub Freezer:
Tiv thaiv kom tsis txhob ya raws ntawm qhov chaw ntawm cov khoom noj khov thiab tiv thaiv lub freezer hlawv.
3. Tiv thaiv kom tsis txhob muaj ntxhiab hloov:
Muab cov khoom noj sib txawv cais kom tsis txhob muaj ntxhiab hloov thaum lub tub yees lossis cia.
4. Cov cua sov kaw:
Koj tuaj yeem microwave cov zaub mov uas siv cov cua sov- cov hnab yas tiv taus kom khaws cov dej noo (kom paub tseeb tias cov ntaub qhwv yas tsis tuaj yeem cuam tshuam nrog cov zaub mov).
5. Tsis yog-Kev siv zaub mov:
Cov dej noo-Kev pov thawj: Siv los tiv thaiv phau ntawv, khaub ncaws, lossis khoom siv hluav taws xob.
Temporary Sealing: Muab cov fwj uas tsis siv thiab cov thawv ntim khoom kom tiv thaiv kom tsis txhob muaj kab mob los yog kis kab mob.
Kev ceev faj rau kev sivYas qhwv
1. Tsis txhob tiv tauj nrog qhov kub thiab txias: Feem ntau cov ntaub qhwv yas tsis haum rau kev sib cuag ncaj qha nrog - cov zaub mov kub thiab tej zaum yuav tso cov khoom tsis zoo.
2. o tsis txhob qhwv cov khoom noj oily ncaj qha: tshwj xeeb tshaj yog cov ntaub ntawv PVC, uas tuaj yeem ua rau muaj roj thiab yaj cov khoom tsis zoo.
3. Tsis haum rau ntev - lub sij hawm cia: yas qhwv yog tsim rau luv luv - lub sij hawm preservation, thiab nws yog pom zoo kom siv cov kev cia ntim rau ntev - lub sij hawm cia.
