Iphepha le-PP elithintela ilangatye liphepha leplastiki elenziwe nge-resin ye-PP, elinezongezo ezahlukeneyo ezisebenzayo ezongezwayo ngokusebenzisa i-extrusion, i-calendar, i-cooling, i-cutting kunye nezinye iinkqubo. Iphepha le-PP elithintela ilangatye liyimpahla ye-semi-crystalline. Linzima kune-PE kwaye linendawo ephezulu yokunyibilika. Ngenxa yokuba ubushushu be-PP ye-homopolymer bubuthathaka kakhulu ngaphezu kwe-0C, izinto ezininzi ze-PP zorhwebo zii-copolymers ezingahleliweyo ezinomxholo we-ethylene we-1-4% okanye ii-block copolymers ezinomxholo ophezulu we-ethylene. Izinto ze-PP ze-Copolymer zinobushushu obuphantsi bokujika kobushushu (100°C), ukukhanya okuphantsi, ukukhanya okuphantsi, kunye nokuqina okuphantsi, kodwa zinamandla amakhulu empembelelo. Ke, ungawubona njani umgangatho wephepha le-PP elithintela ilangatye?

1. Jonga i-gloss yayo engaphezulu. I-gloss engalunganga yiplastiki esetyenzisiweyo.

2. Qaphela ukuqina kwayo. Iphepha lePP eligcina ilangatye elicocekileyo linokuqina okugqwesileyo kwaye linokugobeka kancinci.

3. Jonga umphezulu wokusika. Emva kokusika iplastiki esetyenzisiweyo, kuya kubakho iintlobo ngeentlobo zeenkunkuma ezinemibala eyahlukeneyo.

4. Jonga uxinano lwayo. Uxinano lwe-PP polypropylene yi-0.92 ~ 0.93. Zonke izinto ezidada emanzini ziyi-polypropylene.

5. Iphepha le-PP elithintela ilangatye liyafudunyezwa kwaye lifakwe i-weld. Umsi uyaphuma xa kudityaniswa iplastiki esetyenzisiweyo.

6. Ukuhanjiswa kokukhanya, iiplastiki ezisetyenzisiweyo azidluliseli ukukhanya kakuhle.

7. Ukuqina, iplastiki ephinde yasetyenziswa nayo imbi kakhulu.

8. Uxinano lwephepha le-PP elithintela ilangatye, liphose emanzini ukuze ubone ukuba liyadada phezu kwamanzi, uninzi lwamanzi asetyenzisiweyo ayatshona ezantsi.
