Kodi Zotengera Zakudya Zapulasitiki Zimapangidwa Bwanji? Chidule Chachidule

Zotengera zakudya za pulasitiki, omwe amagwiritsidwa ntchito tsiku ndi tsiku, angawoneke ngati osavuta, koma amafunikira mmisiri waluso komanso kuwongolera bwino kwambiri kuti zitsimikizire chitetezo ndi kulimba. Mukufuna kudziwa momwe amasinthira kuchokera pamapulasitiki apulasitiki kukhala zotengera patebulo lanu lodyera? Nkhaniyi ipereka chidule cha njira yopangira, ndikuwonetseni mwachangu njira zazikulu zopangira.

Gawo loyamba popanga zotengera zakudya zapulasitiki ndikusankha zida zoyenera. Chakudya chodziwika-mapulasitiki agiredi ndi:
• Polypropylene (PP):Kutentha kwapamwamba komanso kusasunthika kwa mankhwala, koyenera kuti muzitha kukhala ndi ma microwave, mabokosi ophimbidwa ndi nkhomaliro, ndi zotengera -zosunga kutentha kwambiri.
• Polyethylene (PE):Zosinthasintha komanso zotsika-zosatentha, zomwe zimagwiritsidwa ntchito ngati zoonda-zotengera zokhala ndi mipanda ndi matumba olongedza zakudya.
• Polystyrene (PS):Kuwonekera kwapamwamba komanso kusasunthika kwabwino, kungagwiritsidwe ntchito kupanga zotengera zakudya zotayidwa ndi mabokosi owonekera.
• Polyethylene Terephthalate (PET):Zowoneka bwino kwambiri komanso zotchinga, zoyenera mabotolo a zakumwa, zotengera zakudya zomveka bwino, komanso zokonzeka-ku{1}}kudya.

Nkhungu zili pamtima pakupanga zidebe za pulasitiki zopangira chakudya, ndipo kapangidwe kake kamadziwikiratu mawonekedwe a chidebecho, kulondola kwake, mphamvu zamapangidwe, komanso magwiridwe antchito. Maonekedwe apamwamba-amawonetsetsa kuti zinthu zikuchulukirachulukira, pomwe mapangidwe apadera amatha kukhala ndi zinthu monga stackability, airtight sealing, kapena compartmentalization. YANGRUI ikupereka mathero-ku-kutha ntchito za nkhungu, kuyambira pamalingaliro azinthu mpaka kupanga nkhungu, kuwongolera mosamalitsa kulekerera kwapang'onopang'ono ndi kutsirizika kwapamwamba kuwonetsetsa kuti chidebe chilichonse chikukwaniritsa zofunikira zachitetezo chazakudya pomwe chimakhala chothandiza komanso chokongola, chopereka mayankho ogwira mtima komanso odalirika pazosowa zosiyanasiyana zonyamula zakudya.

Kupanga zotengera zakudya za pulasitiki nthawi zambiri kumaphatikizapo njira zitatu zowumba:

1. Kuumba jekeseni

Ma pellets a pulasitiki amasungunuka kenaka amabayidwa mopanikizika kwambiri mu nkhungu pogwiritsa ntchito screw kapena jekeseni. Ukazizira ndi kulimba, chidebecho chimachotsedwa mu nkhungu. Njirayi ndi yoyenera kupanga zotengera zovuta, zolimba monga mabokosi otsekedwa ndi ma tray ambiri-odya chakudya m'chipinda.

2. Kuwomba Kuumba

Pulasitiki yosungunuka imapangidwa kukhala tubular preform, yoyikidwa mkati mwa nkhungu, ndikukulitsidwa kumakoma a nkhungu pogwiritsa ntchito mpweya woponderezedwa kuti apange zotengera zopanda kanthu. Pambuyo pozizira, chidebecho chimaphwanyidwa. Njirayi ndi yoyenera mabotolo a zakumwa komanso -zotengera zazikulu zosungirako.

3. Thermoforming

Pepala lapulasitiki limatenthedwa ndikufewetsa, kenako limayikidwa pamwamba pa nkhungu. Chidebecho chimapangidwa pogwiritsa ntchito vacuum suction kapena pressure. Pambuyo pozizira, mawonekedwe a nkhungu amasungidwa. Njira imeneyi ndi yoyenera kupanga mabokosi a nkhomaliro, mathireyi, ndi zopaka zoonda-zokhala ndi mipanda.

Akapangidwa, zotengera zakudya za pulasitiki zimasinthidwa kangapo-kukonza masitepe, kuphatikiza kudula, kusindikiza, kumaliza pamwamba, ndi kusindikiza kapena kulemba zilembo, kuti zitsimikizire kukongola komanso magwiridwe antchito. Kuwongolera kwaubwino kumayendera nthawi yonse yopanga, kuyambira pakuwunika kwazinthu zopangira ndikuwunika kulondola kwa nkhungu mpaka kuwunika komaliza, kulimba, komanso kutsata chitetezo cha chakudya. YANGRUI imagwiritsa ntchito zida zoyezera zapamwamba komanso njira yoyendetsera bwino kuti iunike mozama-zotengera zomwe zapangidwa, kuwonetsetsa kuti chilichonse chili chotetezeka, chodalirika, komanso chikugwirizana ndi miyezo yapadziko lonse yokhudzana ndi chitetezo cha chakudya.

Mukatha kuumba, -kukonza, ndi kuyang'anitsitsa bwino, zotengera zakudya zapulasitiki zimayikidwa kuti zisawonongeke panthawi yoyendetsa ndi kusunga. Kutengera mtundu wa chinthu komanso zomwe makasitomala amafuna, makontena atha kupakidwa molingana ndi gulu, kuunikidwa pamapallet, kapena osindikizidwa-osindikizidwa kuti atsimikizire zadongosolo, chitetezo, ndi kugwidwa mosavuta.

Kupanga motengera chakudya cha pulasitiki kumayamba ndi kusankha zakudya{{0}zopangira zakudya, zotsatiridwa ndi kapangidwe ka nkhungu ndikusintha mwamakonda. Chidebecho chimapangidwa kudzera mu jakisoni, blow molding, kapena thermoforming ndipo chimasinthidwa-kukonzedwa ndikuwunikiridwa mosamalitsa. Pomaliza, imapakidwa ndikugawidwa, ndikufikira m'manja mwanu mosamala.

YANGRUI imapereka mayankho abwino kwambiri-pamitundu yonse yazakudya, kuwonetsetsa kuti chinthu chilichonse chimakhala chokoma kwambiri kuyambira paziwisi mpaka zomalizidwa.Lumikizanani nafelero chifukwa cha mayankho a akatswiri.
