Kusankha lamba loyenera la PP (chingwe cha polypropylene) m'lifupi ndikofunikira pachitetezo cha katundu, kugwirizana kwa zida, komanso kugwiritsa ntchito bwino ndalama. Chingwe cha PP chimapezeka m'lifupi mwake kuyambira 5mm mpaka 19mm. Zingwe zocheperako (5-9mm) zimakwanira makatoni opepuka ndi malonda a e-commerce, pomwe zingwe zokulirapo (12-19mm) zimanyamula ma pallet olemetsa ndi katundu wamafakitale.

Chingwe cha PP (chingwe cha polypropylene) chimapereka mphamvu zopumira kuyambira 45kg mpaka 230kg kutengera m'lifupi ndi makulidwe. Izi zimagwira ntchito kuyambira kusindikiza makatoni opepuka mpaka kumangirira pallet zolemera.

PP zomangira (zomangira polypropylene) likupezeka makulidwe kuchokera 0.35mm mpaka 0.80mm, ndi mtundu uliwonse woyenererana ndi zofunikira za katundu, mitundu ya zida, ndi zosowa zosindikiza. Zingwe zoonda (0.35-0.45mm) zimagwiritsa ntchito makatoni opepuka komanso ma e-commerce, pomwe zosankha zokulirapo (0.55-0.80mm) zimagwira makatoni amankhwala, katundu wapallet, komanso kugulitsa mafakitale.

Kumanga kwa PP (polypropylene strapping) kumatenga mphamvu zake kuchokera ku magawo atatu opanga: extrusion, kutambasula, ndi kuyanjanitsa kwa maselo. Pa extrusion, utomoni wa polypropylene umasungunuka ndikupangidwa kukhala gulu lathyathyathya mosalekeza.

Chingwe cha PP (chingwe cha polypropylene) chimakhala ndi moyo wosungirako wovomerezeka wa miyezi 12-24 pansi pamikhalidwe yoyenera. Kutentha, chinyezi, kuwonekera kwa UV, ndi kukhulupirika kwa phukusi zonse zimakhudza momwe chingwe cha PP chimakhalira nthawi yayitali.

Chingwe cha PP (chingwe cha polypropylene) chimapeza mphamvu kudzera munjira yopangira yotchedwa molecular orientation. Pakupanga, chingwe chowonjezera chimatambasulidwa pansi pamikhalidwe yoyendetsedwa, kugwirizanitsa maunyolo a polima mozungulira kutalika kwa chingwecho.

Zomangira za PP (zomanga za polypropylene) zimapezeka m'lifupi mwake kuyambira 5mm mpaka 19mm, ndi 9mm, 12mm, 15mm, ndi 19mm kukhala makulidwe ambiri. Kusankha m'lifupi kumatsimikizira kugawa katundu, mphamvu yopuma, ndi kugwirizanitsa zipangizo. Zingwe zocheperako (5-9mm) zimakwanira makatoni opepuka komanso ma e-commerce, pomwe zosankha zazikulu (15-19mm) zimanyamula ma pallet olemetsa ndi katundu wamafakitale. Bukhuli likufotokoza m'lifupi mwake momwe PP zomangira zingwe zimakhalira, momwe m'lifupi zimakhudzira magwiridwe antchito, ndi momwe mungasankhire zomwe mukufuna kugwiritsa ntchito.

Chingwe cha PP (chingwe cha polypropylene) chimapezeka mu makulidwe kuyambira 0.35mm mpaka 0.80mm, ndipo mtundu uliwonse umagwirizana ndi zofunikira zinazake komanso mitundu ya zida. Zingwe zoonda (0.35-0.45mm) zimagwiritsa ntchito makatoni opepuka komanso ma e-commerce, pomwe zosankha zokulirapo (0.65-0.80mm) zimanyamula ma pallet olemetsa ndi katundu wamafakitale. Makulidwe amakhudza mwachindunji mphamvu yopuma, magwiridwe antchito a chisindikizo, ndi kudalirika kwa kudyetsa makina. Bukhuli likufotokoza za makulidwe omwe amapezeka pa chingwe cha PP, momwe makulidwe amagwirizanirana ndi kuswa mphamvu, ndi momwe mungasankhire zomwe mukufuna kugwiritsa ntchito.

Kusankha pakati pa PP zomangira magiredi kumakhudza magwiridwe antchito anthawi yayitali kuposa momwe ogula ambiri amaganizira. Zomangira za polypropylene zowoneka bwino kwambiri - zopangidwa kuchokera ku utomoni wokhala ndi kukhuthala kwamkati pakati pa 0.60 ndi 0.95 dl/g - zimapereka utali wa mamolekyu apamwamba kwambiri, zomwe zimapangitsa kuti azikhala ndi mphamvu zolimba kwambiri, kukana kukwawa bwino, komanso kusunga magwiridwe antchito pakapita nthawi. Zomangira za PP zokhazikika zimatha kugwira ntchito mokwanira kwakanthawi kochepa kapena zopepuka koma zimatha kutaya mphamvu mwachangu ponyamula katundu wokhazikika. Nkhaniyi ikufanizira magiredi onse pamitundu yonse ya mamolekyu, mawonekedwe amakanika, ndi magwiridwe antchito anthawi yayitali kuthandiza ogula kusankha zoyenera.

Zomangira za PP (zomangira za polypropylene) ndiye zida zomangira zomwe zimagwiritsidwa ntchito kwambiri popaka utoto wopepuka mpaka wapakatikati. Wopangidwa kuchokera ku utomoni wa polypropylene kudzera mu njira zowonjezera ndi zotambasula, PP zomangira zimaphatikiza kusinthasintha, kutsika mtengo, komanso kugwiritsa ntchito mosavuta. Malinga ndi Signode, wopanga zingwe zotsogola, zomangira za PP zidapangidwa kuti zizipanga palletizing, kugwirizanitsa, kumanga, kutseka makatoni ndi kulimbikitsa.
