Mawotchi katundu
The PP ritsa ali crystallinity mkulu ndi dongosolo zonse, n'kukhala ndi katundu kwambiri makina. Komabe, firiji ndi kutentha otsika, mphamvu amadza ndi osauka chifukwa digiri yapamwamba ya maselo dongosolo mosalekeza. Sewerolo chapadera cha PP chitoliro ndi kukana kuti kupinda kutopa, lodziwika bwino ndi dzina zomatira zana khola.
Matenthedwe ntchito
The PP mpweya ritsa ali wabwino kutentha kukana, ndi mankhwala akhoza chosawilitsidwa ndi chosawilitsidwa pa kutentha 100 ° C kapena kuposa, ndipo si olumala pa 150 ° C pa chikhalidwe cha palibe mphamvu kunja. The embrittlement kutentha ndi -35 ° C, embrittlement amapezeka m'munsimu -35 ° C, ndi kulimbikira ozizira si abwino monga polyethylene.
Chemical bata
Kukhazikitsidwa kwa PP ritsa mankhwala ndi zabwino kwambiri. Kuwonjezera akuukira ndi moyikirapo sulfuric asidi ndipo ankaganiza asidi nitric, ndi khola kuti zosiyanasiyana reagents zina. Komabe, otsika maselo kulemera aliphatic chimasanduka, chimasanduka onunkhira chimasanduka chlorinated akhoza pansi PP chitoliro. Ndi kutupa, ndi mankhwala bata ake ndi kuchuluka kwa crystallinity ndi kuchita bwino, kotero PP chitoliro ndi oyenera kupanga mipope zosiyanasiyana mankhwala ndi zovekera, zotsatira odana ndi dzimbiri zabwino.
Magetsi ntchito
The PP ritsa ali kwambiri mkulu-pafupipafupi kutchinjiriza ntchito, ndipo popeza nkomwe zimatenga madzi, kutchinjiriza ntchito si bwanji ndi chinyezi. Iwo ali mkulu dielectric zonse ndipo angagwiritsidwe ntchito kuti mkangano mankhwala magetsi kutchinjiriza monga limatuluka kutentha. Lilinso ndi mkulu kusokonezeka voteji ndipo ndi oyenera ntchito ngati chowonjezera magetsi. Iwo ali kukana zabwino voteji ndi kukana Arc, koma ali mkulu magetsi malo amodzi ndi yosavuta zaka ndi mkuwa.
Weather kukana
The PP ritsa amakhudzidwa kuwala ultraviolet, ndi Kuwonjezera okusayidi nthaka, dilauryl thiodipropionate, mpweya wakuda kapena ofanana woyera filler kusintha kukana ake okalamba.
