Iindaba

1, umahluko kwisicelo.
Isikali sokusetyenziswa kweIphepha le-PE: isetyenziswa kakhulu kushishino lweekhemikhali, oomatshini, kushishino lweekhemikhali, kumbane, kwiimpahla, ekupakisheni, ekutyeni nakwamanye amashishini. Isetyenziswa kakhulu kuthutho lwegesi, kubonelelo lwamanzi, ekukhutshweni kwamanzi amdaka, ekunkcenkcesheleni kwezolimo, ekuthuthweni kwemigodi emincinci, kwintsimi yeoyile, kushishino lweekhemikhali, kwiposi nakwiinkonzo zonxibelelwano nakwamanye amacandelo, ingakumbi kuthutho lwegesi.

Ububanzi bokusetyenziswa kweiphepha le-pp: izixhobo ezichasene ne-asidi kunye ne-alkali, izixhobo zokukhusela okusingqongileyo, amanzi amdaka, izixhobo zokukhupha igesi emdaka, inqaba yokukrwela, igumbi elicocekileyo, izixhobo zeefektri ze-semiconductor kunye namashishini anxulumene noko, kwaye ikwayeyona nto ikhethwayo yokwenza iitanki zamanzi zeplastiki, phakathi kwazo amaphepha amakhulu e-PP asetyenziswa kakhulu. Isetyenziselwa ukunyathela ipleyiti, ipleyiti yokubuyisela umva, njl.njl.

2. Umahluko kwiimpawu.

Ibhodi ye-PEithambile, inomlinganiselo othile wokuqina, inamandla okuchasana nempembelelo kunye nokusebenza kakuhle kokuthomalalisa, kwaye ukusebenza kwebhodi ebunjiweyo kungcono; ibhodi ye-PP inobunzima obuphezulu, iimpawu zoomatshini ezingalunganga, ubunzima obuphantsi, kunye nokumelana nokuphazamiseka kunye nokuthomalalisa okubi.

3. Umahluko kwizinto ezisetyenziswayo.

Ibhodi yePP, ekwaziwa ngokuba yiphepha le-polypropylene (PP), yinto enemibala ecacileyo. Iqinile kwaye inendawo yokunyibilika ephezulu kune-PE. Iphepha le-PE liyi-resin ye-thermoplastic enemibala ecacileyo kakhulu, engeyiyo i-polar. Inkangeleko ye-HDPE yokuqala imhlophe njengobisi, kwaye icandelo elincinci likhanya ukuya kwinqanaba elithile.
