M'dziko lamakono lomwe likuyenda mofulumira, matumba apulasitiki akhala gawo lofunika kwambiri pa moyo wathu watsiku ndi tsiku. Kuyambira kugula zakudya mpaka kulongedza katundu, matumba amenewa amagwiritsidwa ntchito m'njira zosiyanasiyana. Komabe, kupanga matumba apulasitiki ndi njira yovuta yokhudza makina apadera otchedwa makina opangira matumba apulasitiki. M'nkhaniyi, tifufuza momwe makinawa amagwirira ntchito ndikuyang'ana kwambiri zipangizo zomwe zimagwiritsidwa ntchito popanga matumba apulasitiki.
Makina opangira matumba apulasitikiapangidwa kuti apange matumba apulasitiki moyenera komanso mochuluka. Makinawa amatha kupanga mitundu yosiyanasiyana ya matumba, kuphatikizapo matumba athyathyathya, matumba a gusset, matumba a vest, ndi zina zotero. Njirayi nthawi zambiri imakhala ndi masitepe angapo ofunikira:
1. Zipangizo zopangira: Zipangizo zazikulu zopangira matumba apulasitiki ndi polyethylene, yomwe ili ndi makulidwe osiyanasiyana, monga polyethylene yotsika kwambiri (LDPE) ndi polyethylene yotsika kwambiri (HDPE). Makina opangira matumba apulasitiki amayamba kupatsa ma pellets a utomoni wa pulasitiki mu extruder.
2. Kutulutsa: Chotulutsa chimasungunula ma pellets a pulasitiki ndikupanga chubu chopitilira cha pulasitiki yosungunuka. Njirayi ndi yofunika kwambiri chifukwa imatsimikizira makulidwe ndi mtundu wa chinthu chomaliza.
3. Kuumba ndi Kuziziritsa: Pankhani ya kutulutsa filimu yophwanyidwa, mpweya umalowetsedwa mu chubu chosungunuka kuti chifutukuke kuti chipange filimu. Kenako filimuyo imaziziritsidwa ndi kulimba pamene ikudutsa mu ma rollers angapo.
4. Kudula ndi Kutseka: Filimu ikapangidwa, imadulidwa kutalika kofunikira ndikutsekedwa pansi kuti ipange thumba. Njira yotseka ikhoza kuphatikizapo kutseka kutentha kapena kutseka kwa ultrasound, kutengera kapangidwe ka makina ndi mtundu wa thumba lomwe likupangidwa.
5. Kusindikiza ndi Kumaliza: Makina ambiri opangira matumba apulasitiki ali ndi luso losindikiza lomwe limalola opanga kusindikiza ma logo, mapangidwe, kapena mauthenga mwachindunji m'matumba. Pambuyo posindikiza, matumbawo amayesedwa bwino asanapakedwe kuti agawidwe.
Chonde onani zomwe kampani yathu yachita pankhaniyi,Makina Opangira Makina Opangira Matumba a Pulasitiki a LQ-700 Opanda Zowononga Zachilengedwe
Makina a LQ-700 ndi makina oboola pansi otsekera thumba. Makinawa ali ndi mayunitsi awiri opindika ndi V, ndipo filimu imatha kupindika kamodzi kapena kawiri. Chabwino kwambiri ndichakuti malo opindika ndi katatu asinthidwe. Kapangidwe ka makina kotsekera ndi kuboola poyamba, kenako kupindika ndi kubwerera m'mbuyo kumapeto. Ma V-fold awiri amapangitsa filimu kukhala yaying'ono komanso yotseka pansi.
Zipangizo zomwe zimagwiritsidwa ntchito kwambiri popanga matumba apulasitiki ndi polyethylene ndi polypropylene. Chida chilichonse chili ndi mawonekedwe akeake, zomwe zimapangitsa kuti chigwiritsidwe ntchito mosiyanasiyana.
1. Polyethylene (PE):Ichi ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri popanga matumba apulasitiki. Chimabwera m'njira ziwiri zazikulu:
- Polyethylene Yochepa Kwambiri (LDPE): LDPE imadziwika ndi kusinthasintha kwake komanso kufewa kwake. Imagwiritsidwa ntchito kwambiri popanga matumba ogulitsa zakudya, matumba a buledi, ndi zina zopepuka. Matumba a LDPE si olimba ngati matumba a HDPE, koma amalimba kwambiri ku chinyezi.
- High Density Polyethylene (HDPE): HDPE ndi yolimba komanso yolimba kuposa LDPE. Nthawi zambiri imagwiritsidwa ntchito popanga matumba okhuthala, monga omwe amagwiritsidwa ntchito m'masitolo ogulitsa. Matumba a HDPE amadziwika kuti satha kung'ambika ndipo nthawi zambiri amagwiritsidwa ntchito kunyamula zinthu zolemera.
2. Polypropylene (PP):Polypropylene ndi chinthu china chodziwika bwino chopangira matumba apulasitiki, makamaka matumba ogulira omwe angagwiritsidwenso ntchito. Ndi olimba kuposa polyethylene, imakhala ndi malo osungunuka kwambiri, ndipo ndi yoyenera kugwiritsidwa ntchito yomwe imafuna mphamvu komanso kukana kutentha. Matumba a PP nthawi zambiri amagwiritsidwa ntchito polongedza chakudya chifukwa amapereka chotchinga chabwino ku chinyezi ndi mankhwala.
3. Mapulasitiki osinthika:Popeza anthu akuda nkhawa kwambiri ndi nkhani zachilengedwe, mapulasitiki otha kuwonongeka akhala otchuka kwambiri m'zaka zaposachedwa. Zipangizozi zimawonongeka mofulumira kuposa mapulasitiki akale, zomwe zimachepetsa kuwonongeka kwa chilengedwe. Ngakhale kuti matumba otha kuwonongeka akadali ochepa poyerekeza ndi matumba a polyethylene ndi polypropylene, akugwiritsidwa ntchito kwambiri ndi ogula komanso mabizinesi omwe amasamala za chilengedwe.
Kupanga ndi kugwiritsa ntchito matumba apulasitiki kwabweretsa mavuto aakulu azachilengedwe. Mapepala apulasitiki amayambitsa kuipitsa chilengedwe ndipo angatenge zaka mazana ambiri kuti awonongeke m'malo otayira zinyalala. Chifukwa cha zimenezi, mayiko ndi mizinda yambiri yakhazikitsa ziletso kapena ziletso pa matumba apulasitiki ogwiritsidwa ntchito kamodzi kokha, zomwe zalimbikitsa kugwiritsa ntchito njira zina zomwe zingagwiritsidwenso ntchito.
Opanga makina opangira matumba apulasitikiakusinthanso malinga ndi kusinthaku, akupanga makina omwe angapange matumba kapena matumba owonongeka opangidwa kuchokera ku zinthu zobwezerezedwanso. Kusinthaku sikungothandiza kuchepetsa kuwonongeka kwa matumba apulasitiki, komanso kukwaniritsa kufunikira kwakukulu kwa njira zosungiramo zinthu zokhazikika.
Makina opangira matumba apulasitiki amagwira ntchito yofunika kwambiri popanga chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri pamoyo wathu watsiku ndi tsiku. Kumvetsetsa zipangizo zomwe zimagwiritsidwa ntchito popanga matumba apulasitiki, monga polyethylene ndi polypropylene, ndikofunikira kwambiri kwa opanga ndi ogula. Pamene makampani akukula, ndikofunikira kuganizira za momwe kugwiritsa ntchito matumba apulasitiki kungakhudzire chilengedwe ndikufufuza njira zina zokhazikika. Mwa kulandira luso latsopano komanso machitidwe abwino, titha kugwira ntchito kuti tipeze tsogolo lomwematumba apulasitikiamapangidwa ndikugwiritsidwa ntchito m'njira yochepetsera mphamvu zawo padziko lapansi.
