M'zaka zaposachedwapa, gawo logwiritsira ntchito machubu lakula pang'onopang'ono. Mu makampani opanga zodzoladzola, zodzoladzola, kugwiritsa ntchito tsiku ndi tsiku, kutsuka ndi kusamalira zinthu zimakonda kwambiri kugwiritsa ntchito machubu odzola, chifukwa chubucho ndi chosavuta kufinya, chosavuta kugwiritsa ntchito, chopepuka komanso chosavuta kunyamula, ndipo chikhoza kusinthidwa kuti chigwirizane ndi zofunikira ndi kusindikiza.Chubu cha PE(chubu chopangidwa ndi pulasitiki yonse) ndi chimodzi mwa machubu odziwika bwino. Tiyeni tiwone chomwe chubu cha PE chili.
Zigawo za PETube
Thupi lalikulu: thupi la chubu, phewa la chubu, mchira wa chubu
Kufananiza:chubu cap, rmpira wa mpira, mutu wotikita minofu, ndi zina zotero.
Zipangizo za PE Tube
Zinthu zazikulu: LDPE, Zomatira, EVOH
Zinthu zothandizira: LLDPE, MDPE , HDPE
Mitundu ya PETube
Malinga ndi kapangidwe ka thupi la chitoliro: chitoliro chokhala ndi gawo limodzi, chitoliro chokhala ndi magawo awiri, chitoliro chophatikizika
Malinga ndi mtundu wa thupi la chubu: chubu chowonekera, chubu choyera, chubu chamitundu
Malinga ndi zinthu zomwe zili m'thupi la chubu: chubu chofewa, chubu wamba, chubu cholimba
Malinga ndi mawonekedwe a thupi la chubu: chubu chozungulira, chubu chathyathyathya, chubu cha triangular
Kuyenda kwa Njira ya PE Chubu
Kukoka Machubu → Kuyika Machubu → Kusindikiza (Kusindikiza kwa Offset, Kusindikiza Silika Screen, Kusindikiza kwa Flexo)

Ubwino ndi Kuipa kwa PE Tube
Ubwino:
a. Wosamalira chilengedwe.Poyerekeza ndi machubu opangidwa ndi aluminiyamu ndi pulasitiki, machubu opangidwa ndi pulasitiki yonse amagwiritsa ntchito mapepala opangidwa ndi pulasitiki yonse otsika mtengo komanso osavuta kubwezeretsanso, zomwe zimachepetsa kuipitsidwa kwa chilengedwe chifukwa cha zinyalala zolongedza. Machubu opangidwa ndi pulasitiki yonse yokonzedwanso amatha kupangidwa atakonzedwanso akhoza kupanga zinthu zochepa.
b. Mitundu yosiyanasiyana.Malinga ndi makhalidwe a zodzoladzola ndi zosowa zosiyanasiyana za ogula, machubu opangidwa ndi pulasitiki yokha amatha kupangidwa kukhala mitundu yosiyanasiyana, monga yopanda utoto ndi yowonekera, yowonekera, yowoneka bwino, ndi zina zotero, kuti ogula azisangalala kwambiri ndi mawonekedwe awo. Makamaka chubu chopangidwa ndi pulasitiki yokha chomwe chimaonekera bwino chimatha kuwona bwino momwe zinthu zilili, kupatsa anthu mawonekedwe amphamvu komanso kulimbikitsa kwambiri chikhumbo cha ogula chogula.
c. Kulimba mtima kwabwino.Poyerekeza ndi chubu chopangidwa ndi aluminiyamu-pulasitiki, chubu chopangidwa ndi pulasitiki yonse chimakhala ndi mphamvu yolimba, zomwe zimatsimikizira kuti chubucho chimatha kubwerera msanga ku mawonekedwe ake oyambirira mutakanikiza zodzoladzola, ndikukhalabe ndi mawonekedwe okongola nthawi zonse. Izi ndizofunikira kwambiri pakulongedza zodzoladzola.
Zoyipa:
Kapangidwe ka chotchinga cha chubu chopangidwa ndi pulasitiki yonse kamadalira kwambiri mtundu ndi makulidwe a chotchingacho. Potengera EVOH ngati chotchinga cha chubu chopangidwa ndi pulasitiki yonse mwachitsanzo, kuti chikhale chotchinga chomwecho komanso kuuma kwake, mtengo wake ndi wokwera ndi pafupifupi 20% mpaka 30% kuposa payipi yopangidwa ndi aluminiyamu. Kwa nthawi yayitali mtsogolomu, izi zidzakhala chinthu chachikulu chomwe chimachepetsa kusintha kwathunthu kwa machubu opangidwa ndi aluminiyamu-pulasitiki ndi machubu opangidwa ndi pulasitiki yonse.
