Zolinga zolongedza, lamba la polypropylene PP mosakayikira ndilofunika kwambiri. Zomangira zopepuka izi ndizambiri chifukwa ndizotsika mtengo, zitha kugwiritsidwa ntchito m'njira zambiri, ndipo zimagwira ntchito bwino nthawi zonse. Chifukwa amapangidwa kuchokera ku polima wosinthika, chingwe cha polypropylene PP ndichotsika mtengo kwambiri

Kuti musankhe kukula kwa zingwe za PP, muyenera kuganizira mozama za katundu wanu komanso zosowa za pulogalamu yanu. Magulu a PP, omwe amapangidwa kuchokera ku polypropylene, ndi osinthika kwambiri komanso otsika mtengo kuti agwiritse ntchito kuwala kwapakati. Zofunika kwambiri ndi kulemera kwa katundu, kukula kwa phukusi

Kufananiza lamba la PP ku makina anu omangira ndikoposa kusankha m'lifupi moyenerera—ndizokhudza kuwonetsetsa kuti makina amagwirizana pamiyeso yonse, mawonekedwe amipukutu, ndi zinthu zakuthupi. Zingwe zosagwirizana zimatha kuyambitsa zolakwika za chakudya, zosindikizira zofooka, kukangana kosagwirizana, komanso kutsika mtengo.

Zomangira za PP (zomangira za polypropylene) zimapereka kusinthasintha kuti zigwirizane ndi zomwe mukufuna. M'lifupi kuchokera pa 5mm mpaka 19mm ndi makulidwe kuchokera ku 0.35mm mpaka 1.2mm amalola chilichonse kuyambira makatoni opepuka mpaka katundu wolemetsa. Bukhuli likuwunika momwe mungasankhire makonda, njira zosankhidwa, ndi zotsatira za kusankha kwatsatanetsatane pakugwirizana kwa zida ndi momwe mumapangira.

Kusankha wogulitsa zingwe za thonje kumafuna kuunika koyenera kwa luso la kupanga, machitidwe otsimikiza, ndi kutsata malamulo. Zolinga zazikuluzikulu zikuphatikiza kutsimikizira kwamphamvu, zolembedwa za certification, ndi kutsata kwa JCIBPC. Bukuli limathandiza ogula kuwunika mwadongosolo ogulitsa zingwe za thonje.

Kwa makina onyamula okha, kusankha chingwe choyenera cha PP kumatanthauza kudziwa momwe mungakwaniritsire zofunikira za njira zothamanga kwambiri. Zinthu zambiri zimatha kupangidwa ndi polypropylene kumanga chifukwa ndizopepuka komanso zamphamvu kuti zisunge mawonekedwe ake pakapita nthawi. Zomangira zomwe zimadya mosavuta, nyanja

Kusankha lamba loyenera la thonje ndikofunikira poteteza mtundu wa thonje panthawi yotumiza kunja. Bukuli likuphatikiza zofunikira za mphamvu yopuma pamiyezo ya USDA ndi JCIBPC, m'lifupi ndi makulidwe ake, komanso zabwino za PET pazingwe zachitsulo. Ogulitsa kunja akuyenera kuwonetsetsa kuti zingwe zawo zikugwirizana ndi mphamvu yopuma yochepera 2,400-3,200 mapaundi kutengera mtundu wa bale, ndikuyika koyenera kuti ateteze zida zomangira kuti zisamagwire mphamvu.

Funso loti chingwe cha PET (chingwe cha poliyesitala) chingalowe m'malo mwa zingwe zachitsulo ndi chimodzi mwamafunso omwe amapezeka kuchokera kwa ogula mafakitale. Ndi mphamvu zolimba mpaka 600 N/mm², zomangira PET zimatha kukwaniritsa zofunikira zambiri zolemetsa kwinaku zikupereka maubwino olemera, chitetezo, ndi mtengo. Komabe, zosankha zolowa m'malo zimatengera zomwe mukufuna komanso momwe mungagwiritsire ntchito. Bukuli likufanizira PET ndi zingwe zachitsulo pamiyeso yayikulu yogwirira ntchito kuti athandize ogula kupanga zisankho mwanzeru.

Zingwe zachitsulo zachikhalidwe ndi polypropylene sizabwino ngati zomangira za PET pankhani yosankha lamba labwino kwambiri lolongedza thonje. Mafakitole amakono omwe amakonza thonje amafunikira zida zonyamulira zomwe zimakhala zamphamvu kwambiri, zomwe sizizimiririka ndi kuwala kwa UV, komanso kutentha. Zingwe za thonje za PET

Zomangira za PET (polyester) zimadziwikiratu ngati njira yabwino kwambiri paulimi wamakono ndi ntchito zoyendera mukamayang'ana lamba labwino kwambiri la kuponderezana kwa thonje ndi kusunga. Kulimba kwamphamvu kwazinthu zotengera zachilengedwezi kumachokera ku 180 kg mpaka 1360 kg mphamvu yopuma. Iwo ali bwino pa
