Menene Halayen Polypropylene (PP)?

Wasu daga cikin mahimman kaddarorin polypropylene sune:
1.Chemical Resistance: Diluted tushe da acid ba su amsa da sauri tare da polypropylene, wanda ya sa ya zama mai kyau zabi ga kwantena na irin wannan taya, kamar tsaftacewa jamiái, farko-aid kayayyakin, da sauransu.
2.Elasticity da Tauri: Polypropylene zai yi aiki tare da elasticity a kan wani nau'i na juzu'i (kamar duk kayan aiki), amma kuma zai fuskanci nakasar filastik da wuri a cikin tsarin nakasa, don haka ana la'akari da shi a matsayin "m" abu.Tauri kalma ce ta injiniya wacce aka ayyana a matsayin ikon abu na lalacewa (plastically, ba na roba) ba tare da karyewa ba.
3.Fatigue Resistance: Polypropylene yana riƙe da siffarsa bayan mai yawa torsion, lankwasawa, da / ko sassauƙa.Wannan kayan yana da mahimmanci musamman don yin hinges na rayuwa.
4.Insulation: polypropylene yana da matukar juriya ga wutar lantarki kuma yana da amfani sosai ga kayan lantarki.
5.Transmissivity: Ko da yake Polypropylene za a iya sanya m, shi ne kullum samar ya zama ta halitta opaque a launi.Ana iya amfani da polypropylene don aikace-aikace inda wasu canja wurin haske ke da mahimmanci ko kuma inda yake da darajar kyan gani.Idan ana son babban watsawa to robobi kamar acrylic ko polycarbonate sune mafi kyawun zaɓi.
An rarraba polypropylene a matsayin "thermoplastic" (kamar yadda ya saba da "thermoset") abu wanda ke da alaƙa da yadda filastik ke amsa zafi.Abubuwan thermoplastic sun zama ruwa a wurin narkewa (kimanin digiri 130 ma'aunin celcius a yanayin polypropylene).
Babban sifa mai amfani game da thermoplastics shine za'a iya mai da su zuwa wurin narkewa, sanyaya, kuma a sake sake yin zafi ba tare da raguwa mai yawa ba.Maimakon kona, thermoplastics kamar polypropylene liquefy, wanda ke ba su damar yin allura cikin sauƙi sannan a sake yin amfani da su.
Sabanin haka, robobi na thermoset za a iya dumama sau ɗaya kawai (yawanci yayin aikin gyaran allura).Na farko dumama yana sa kayan thermoset saita saita (kama da epoxy part 2) wanda ke haifar da canjin sinadarai wanda ba za a iya juyawa ba.Idan kayi ƙoƙarin dumama robobin thermoset zuwa babban zafin jiki a karo na biyu zai ƙone kawai.Wannan halayyar ta sa kayan thermoset su zama matalauta masu neman sake amfani da su.
