Kodi chimachitika PVC filimu ndi mmene umaonekera

Kenaka zipangizo akhala m'modzi wa mitundu ikuluikulu ya mankhwala ankadya ndi makampani mu XX atumwi. Pali zifukwa kuganiza kuti phindu m'nthawi ichi chidzachulukira yekha. A malo apadera mwa zinthuzi amatenga PVC filimu (PVC).

Kenaka ayenera ntchito zingapo. cholinga chake chachikulu - Mankhwala kutetezedwa njiru kunja makhalidwe, dothi ndi kuwonongeka pa mayendedwe ndi ndondomeko malonda. Ndi zinthu zina zofunika kuti kulimbikitsa zolinga wogula, monga maonekedwe yokongola ndi chidaliro chakuti poyamba phunziro anasankha palibe munthu ntchito kapena ngakhale anamukhudza. PVC filimu akuyerekeza akutsutsana ndi katundu bwino pulasitiki kuwala ndi kuthekera ntchito kwa ma CD zakudya zambiri.

PVC zimalimbikitsa kufala kwa kuphweka wachibale wa sayansi. A granular MABUKU (polima) zimalowa ndi extruder kumene kusungunula. Ndiye izo Nkhuntho kuchokera kuwira lalikulu, mumakhala gwero la wosanjikiza mosalekeza, kudula kwa anakhumba m'lifupi ndi bala pa bobbins.

PVC filimu ntchito makampani chakudya ndi malonda lili ndi mitundu iwiri ya Tambasula ndi kutentha shrinkable. Aliyense ali ndi cholinga chake.

Tambasula - PVC filimu ntchito kukulunga malonda ake popanda kulenga china chotulutsa. Iwo amakhala ndi katundu wapadera makina, monga luso kutambasula ndi interlayer guluu wolimba chifukwa mapangidwe a minda electrostatic ndi intermolecular kukopa. Ambiri ntchito ndi mabungwe malonda kulenga zinthu ukhondo pa yosungirako ndi kugulitsa katundu.

PVC kuotcha filimu yodziwika ndi luso la kuchepa miyeso geometrical mchikakamizo cha kutentha. Kuti awutenge katundu mu izo, muyenera kuchita ntchito zofunikira ziwiri: solder dera ndi mpando. Izo zinabala mu mawonekedwe a theka malaya (i.e., apangidwe mu theka m'lifupi) kapena manja, youmba mu masikono. Anatsekera ntchito pa weldres mafakitale, nthawi zambiri, okhota, ndipo anapanga atakhala, amangoona mkangano mpweya otaya.

Malinga ndi katundu n'cholinga kunyamulidwa, kuchokera osiyanasiyana zilipo pa msika, wosuta amasankha kukula ankafuna. Makhalidwe shrinkable filimu bwinobwino bwino ankachita. Mwachitsanzo, malamulo izikhala pa chizindikiro PVCT 400 * 750 * 15 zikutanthauza kuti theka-malaya mayina ndi m'lifupi mwake masentimita 40, kutalika 750 m, ndi makulidwe a wosanjikiza ndi 15 microns.

Opanga PVC ndiye kuti misa. Mbiri yakale, kuti PVC filimu zimagulitsidwa ndi kulemera.

Pali mtundu uwu zipangizo CD ndi kupanda - pa filimu kuotcha sangathe kusindikiza lemba kapena mafano, monga zolemba afuna molakwika pamene kusintha miyeso zojambula. Komabe, yosalala pamwamba n'zosavuta kumamatira chizindikiro kapena, Kapenanso, enclose pansi pake. Posankha njira ya kalembera wa ntchito, tiyenera kukumbukira kuti kuotcha filimu amalenga kunja wosanjikiza optically mandala amateteza zimakhalapo, fumbi, dothi, ndi kupereka aliyense, ngakhale chinazilala bokosi glossy kuwala.

Chodetsa filimu PVC Tambasula za mofanana kutentha shrinkable, kusiyana kwagona kuti chilonda mu wosanjikiza limodzi, choncho amakonda falitsani kutalika kawiri.
