Iikhompawundi ze-LSZH
Intshayelelo yeMveliso
Iikhompawundi ze-LSZH zenziwa ngokuxuba, ukwenza iplastiki, kunye nokwenza i-polyolefin ibe yi-pelletizing njengezinto ezisisiseko kunye nokongezwa kwezinto ezithintela ilangatye ezingaphiliyo, ii-antioxidants, izinto zokuthambisa, kunye nezinye izongezo. Iikhompawundi ze-LSZH zibonisa iipropati ezibalaseleyo zoomatshini kunye nokusebenza okuthintela ilangatye, kunye neempawu ezibalaseleyo zokucubungula. Isetyenziswa kakhulu njengezinto zokugquma kwiintambo zamandla, iintambo zonxibelelwano, iintambo zolawulo, iintambo ze-optical, nokunye.
Isalathisi sokuSebenza
Iikhompawundi ze-LSZH ziyakwazi ukucutshungulwa kakuhle, kwaye zinokucutshungulwa kusetyenziswa izikrufu ze-PVC okanye ze-PE. Nangona kunjalo, ukuze kufezekiswe iziphumo ezilungileyo zokukhupha, kucetyiswa ukusebenzisa izikrufu ezinomlinganiselo woxinzelelo we-1:1.5. Ngokwesiqhelo, sicebisa le miqathango ilandelayo yokucubungula:
- Ubude be-Extruder ukuya kwi-Diameter Ratio (L/D): 20-25
- Iphakheji Yesikrini (I-Mesh): 30-60
Useto lobushushu
| Indawo yokuqala | Indawo yesibini | Indawo yesithathu | Indawo yesine | Indawo yesihlanu |
| 125℃ | 135℃ | 150℃ | 165℃ | 150℃ |
| Ubushushu obungentla bubhekiselele kuphela, ulawulo oluthile lobushushu kufuneka lulungiswe ngokufanelekileyo ngokwezixhobo ezithile. | ||||
Iikhompawundi ze-LSZH zingakhutshwa ngentloko yokukhupha okanye ngentloko yetyhubhu yokucinezela.
