Iipropati Mechanical
I-PP bile iye crystallinity ophezulu kunye nesakhiwo rhoqo, kwaye wenjenje iipropati kakhulu ngoomatshini. Noko ke, bushushu kunye kubushushu obuphantsi, amandla impembelelo ulihlwempu ngenxa iqondo eliphezulu ezinto isakhiwo njalo. Indlela eziqhuba ebalaseleyo ngakumbi umbhobho PP na ukumelana ayeguqa ukudinwa, ngokuqhelekileyo eyaziwa ngokuba le ngcina oluphindwe-ezilikhulu.
Komsebenzi thermal
I-PP umoya bile enokumelana elungileyo ubushushu, kwaye imveliso nga zicocwe kwaye inzala obushushu ka-100 ° C okanye ngaphezulu, kwaye akukho gqitha ku 150 ° C phantsi imeko akukho amandla lwangaphandle. Iqondo lobushushu embrittlement yi 35 ° C, embrittlement kwenzeka ngaphantsi 35 ° C, yaye ukumelana yengqele mgangathweni njengoko polyethylene.
Uzinzo Chemical
Le uzinzo eekhemikhali duct PP kuhle kakhulu. Ngaphandle zihlaselwa sulphuric acid kanzulu ngokwendawo nitric acid, oko uzinzile amanye wezenzi ezahlukeneyo imichiza. Nangona kunjalo, ubunzima molekyuli hydrocarbon ephantsi aliphatic, hydrocarbon ibhedolaki hydrocarbon ikhlorini nga kubongoza umbhobho PP. Kwaye ukudumba, kunye nozinzo yayo ngemichiza kunye nokwanda crystallinity nangakumbi, ngoko PP inqawe ikufanele ukuvelisa kwemibhobho ezahlukeneyo imichiza nokulinganiswa, isiphumo anti-umhlwa ilungile.
Komsebenzi Electrical
I-PP bile uye phezulu-frequency yokusebenza egqwesileyo yokugquma, yaye ekubeni ngenkankulu afunxa amanzi, ukusebenza yokwambathisa alichatshazelwa ukufuma. It has a rhoqo aphezulu Heating kwaye zingasetyenziswa ukwenza iimveliso yokugquma zombane liyavutha ubushushu. Kwakhona unalo ombane aphezulu kwesimilo ilungele ukusetyenziswa njengoko ngesixhobo sombane. It enokumelana ezilungileyo ombane kunye nokumelana arc, kodwa umbane ophezulu engatshintshiyo kwaye kulula yobudala ngobhedu.
Ukumelana Weather
I-PP bile uvakalelo ekukhanyeni yelanga, kunye nokongeza zinc oxide, dilauryl thiodipropionate, icarbon emnyama okanye efanayo lokufaka ezimhlophe unako ukuphucula ukuxhathisa yayo abakhulileyo.
