1. Cua sov thiab cua txias:
Kev txuag hluav taws xob yog qhov tseem ceeb tshaj plaws ntawm cov hnab nqa tawm. Cov hnab ntim tshwj xeeb nrog lub sijhawm luv luv tiv thaiv tshav kub tuaj yeem khaws cov cua sov / txuag hluav taws xob. Cov khoom siv hluav taws xob txuag hluav taws xob siv cov paj rwb pearl, aluminium ntawv ci, thiab tin foil los muab cov txiaj ntsig zoo thaum tshav kub kub.
2, Durability:
yuav tsum muaj kev tiv thaiv zoo tshaj plaws, tsis yooj yim tawg lossis puas nyob rau hauv lub siab hnyav lossis kev sib tsoo.
3, seal:
Qhov no yog lwm qhov kev txiav txim siab thaum xaiv lub hnab nqa khoom. Txawm hais tias cov khoom lag luam sib txawv muaj ntau txoj kev sib khi, kev ua tau zoo sealing yog qhov tsim nyog rau kev khaws cia tsis tu ncua ntawm cov khoom noj khoom haus.
4. Reservation:
Cov txheej txheem sealing thoob ntiaj teb yog ntsuas los ntawm kev ntsuas av noo. Cov av noo ntawm cov hnab ntim khoom zoo yog 200 npaug qis dua li cov khoom zoo sib xws, uas tuaj yeem khaws cov khoom noj tshiab kom ntev dua.
5, ntau qhov ntau thiab tsawg:
Lub hnab nqa tawm tuaj yeem tsim muaj ntau qhov ntau thiab tsawg raws li kev xav tau ntawm kev xa khoom, thiab siv nrog cov pob khov nab kuab rov siv tau. Cov pob khov nab kuab tuaj yeem khaws cov cua sov (cov pob khov nab kuab tuaj yeem khov rau qhov tsawg kawg ntawm -190 degrees, thiab tuaj yeem ua kom sov siab tshaj 200 degrees), thiab tuaj yeem txiav ntawm qhov siab.
6. Kev tiv thaiv ib puag ncig:
Khoom noj khoom haus-qib ib puag ncig cov ntaub ntawv, tsis muaj tshuaj lom, tiv thaiv ultraviolet, tsis yooj yim hloov xim
