Yogurt hau yog dab tsi?

Lawv feem ntau yog ua los ntawm txhuas ntawv ci, nrog rau ib sab coated los yog laminated nrog lwm cov ntaub ntawv, thiab lwm sab coated nrog tshav kub- sealing nplaum. Piv txwv li, tus neeg sawv cev tiv thaiv yog coated rau ntawm ib sab los tsim cov txheej txheem tiv thaiv (txhim kho tus nqi kwv yees li 0.8-1.2 g / m²), lossis nws yog laminated nrog qee cov yas, xws li PP thiab PET, thiab cua sov- sealing nplaum yog coated rau lwm sab los tsim cov cua sov-sealing txheej (coating ntau npaum li cas 1.0 g / m²).

Tom qab txheej txheej, cov txheej yuav tsum tau cua sov thiab ziab (piv txwv li, 160-210 degree) thiab txias (piv txwv li, txias rau 35-45 degree).

Lub tshav kub- txheej sealing, feem ntau yog tsim los ntawm acrylic resin, polyolefin resin, los yog cov ntaub ntawv zoo sib xws, yog ib qho tseem ceeb heev rau kev ua tiav lub foob muaj zog nrog lub khob ntug thaum tseem yooj yim los tsim kua muag.

Aluminium ntawv ci yog cov khoom siv zoo tshaj plaws rau ntim lub hau vim nws cov khoom thaiv zoo heev, kev nyiam huv, thiab kev ua haujlwm ruaj khov. Los ntawm cov txheej txheem dov thiab dyeing, aluminium ntawv nyiaj tau txais txiaj ntsig nrog ob tus nqi ntawm kev tiv thaiv zaub mov thiab muab kev yooj yim ntawm kev siv.

Mengjiang Aluminium tau tsimaluminium ntawv ci rau 17 xyoo, txais tos nug.
