Magadzirirwo ePET (Polyester) Strapping Band anosiyana zvichienderana nekushandiswa kwayo (kurongedza kwakareruka, kwepakati, kana kwakaoma). Pazasi pane zvinhu zvakakosha zvehunyanzvi uye magadzirirwo akafanana:
1. Zvinhu & Zvivakwa
- Zvinhu: Polyethylene Terephthalate (PET)
- Kureba: 2% - 3% (kutambanudza kwakaderera, kwakanakira kugadzikana kwemutoro)
- Simba rekusimba: 300 MPa – 800 MPa (yakasimba kupfuura PP & strapping yesimbi mune dzimwe nguva)
- Tembiricha yekushanda: -40°C kusvika +85°C (inodzivirira kupisa, yakakodzera mamiriro ekunze akaomarara)
- Kudzivirira UV: Yakanaka kwazvo (yakakodzera kuchengeterwa panze)
- Kuramba Hunyoro: Haipindi mvura, haigari ngura kana kuora
- Inogona kushandiswazve: Inoshamwaridzana nezvakatipoteredza, inogona kushandiswazve
2. Saizi Dzakafanana (Upamhi & Ukobvu)
| Upamhi (mm/inch) | Ukobvu (mm) | Simba reKupwanya (kN) | Kushandiswa Kwakajairika |
|---|---|---|---|
| 9 mm (3/8″) | 0.6 – 0.8 mm | 2.5 – 4.0 kN | Kurongedza kwakareruka, makatoni |
| 12 mm (1/2″) | 0.7 – 1.0 mm | 3.5 – 6.0 kN | Kubatanidza zvinhu zvine basa repakati nepakati |
| 15 mm (5/8″) | 0.8 – 1.2 mm | 5.0 – 8.0 kN | Mapallet anorema, zvidhinha |
| 19 mm (3/4″) | 1.0 – 1.5 mm | 7.0 – 12.0 kN | Makoiri esimbi, matanda, kuvaka |
| 25 mm (1″) | 1.2 – 1.8 mm | 10.0 – 20.0 kN | Mitoro inorema zvakanyanya |
3. Sarudzo dzeRuvara
- Standard: Dema, Girini, Chena, Rakajeka
- Zvakagadzirwa: Inowanikwa mumavara akasiyana-siyana (semuenzaniso, bhuruu, tsvuku, yero) yekunyora makodhi kana kuisa mabrandi
4. Kurongedza & Kureba kweRoll
- Kureba kweRoll: Kazhinji 500m, 1000m, kana kureba kwakagadzirwa
- Dhayamita yepakati: 200mm, 300mm (yakajairika)
- Kurema paRoll: Zvinoenderana nehupamhi neukobvu (semuenzaniso, 12mm x 1000m ≈ 8-12 kg)
5. Nzira dzekubatanidza
- Zvishandiso zveKuvhara: Kubatanidza kupisa (zvinowanzoonekwa), zvisimbiso zvesimbi kana zvepurasitiki, makiyi emabhandi
- Zvishandiso Zvinoenderana: Manual tensioners, pneumatic strapping tools, otomatiki michina
6. Mabhenefiti Akakosha vs. Mamwe Mhando dzeStrapping
| Chinhu | Kusunga Zvipfuyo | Kusunga kwePP | Kusunga Simbi |
|---|---|---|---|
| Simba | Yakakwira (300-800 MPa) | Pakati nepakati (200-400 MPa) | Yakakwira Zvikuru (600-1000 MPa) |
| Kureba | Yakaderera (2-3%) | Yakakwira (10-25%) | Zvakaderera Zvikuru (<1%) |
| Huremu | Chiedza | Chiri Chireruka Zvikuru | Zvinorema |
| Ngura | No | No | Ehe (ngura) |
| Mutengo | Zviri pakati nepakati | Zvakaderera | Yakakwirira |
7. Mashandisirwo Akajairika
✔ Zvinhu Zvinoshandiswa & Kutumira (kusunga mabhokisi, kusungirirwa kwemapareti)
✔ Kuvaka (zvidhinha, matanda, madziro emadziro)
✔ Maindasitiri esimbi nepepa (simbi, marongero emapepa)
✔ Kurima (mabhero euswa, mabhegi efetiraiza)
✔ Kurongedza Kunze Kwenyika (kunodzivirira hunyoro, kunogara kwenguva refu)
