Kugwiritsa ntchito
Ndodo ya PP (polypropylene) ndi chinthu cha semi-crystalline chomwe chimadziwika bwino chifukwa cha kuphatikiza kwake kwapadera kwa thupi ndi makina. Chimodzi mwazodziwika kwambiri ndi kuuma kwake komanso malo osungunuka kwambiri, omwe amasiyanitsa ndi zinthu zina monga PE (polyethylene). Ngakhale kuti mtundu wa homopolymer wa PP ukhoza kukhala wosasunthika ukakhala wotentha kwambiri kuposa 0 ° C, zida zambiri zamalonda za PP zimapangidwa ngati ma copolymers mwachisawawa kapena ma clamp copolymer okhala ndi magawo osiyanasiyana a ethylene.
Ma copolymers osasintha amakhala ndi 1 mpaka 4% ethylene, pomwe ma clamp copolymers amakhala ndi chiŵerengero chapamwamba cha ethylene. Njira iyi ya copolymerization imapangitsa kuti zinthu za PP zikhale ndi kutentha kochepa kwa kutentha (100 ° C) poyerekeza ndi homopolymer PP. Ngakhale zinthu zamtundu wa PP zamtundu wa copolymer zitha kukhala zowonekera pang'ono, zonyezimira, komanso zolimba, zimawonetsa mphamvu yamphamvu. Pamene zomwe zili mu ethylene mu copolymer zikuwonjezeka, mphamvu zonse za PP zakuthupi zimawonjezekanso, zomwe zimapangitsa kukhala njira yosinthika pazinthu zosiyanasiyana.
Chikhalidwe china chofunikira cha PP ndi kutentha kwake kwa Vicat, komwe ndi 150 ° C. Kukana kutentha kumeneku, kuphatikizidwa ndi digiri yapamwamba ya crystallinity, kumabweretsa kuuma kwapamwamba kwambiri komanso kukana kukanika. Izi zimapangitsa PP kukhala chisankho chabwino pamapulogalamu omwe kulimba komanso kukana kuvala ndikofunikira.
Kuphatikiza apo, PP imadziwika chifukwa cha kukana kusokonezeka kwa chilengedwe, yomwe ndi nkhani yofala muzinthu zina zambiri. Izi zimapangitsa kukhala chisankho chodalirika kuti chigwiritsidwe ntchito m'malo omwe kukhudzana ndi mankhwala, chinyezi, kapena zovuta zina.
Kuphatikiza pa mawonekedwe ake amakina, PP imaperekanso magwiridwe antchito abwino kwambiri. Ikhoza kupangidwa mosavuta ndikupangidwa pogwiritsa ntchito njira zosiyanasiyana zopangira, monga jekeseni, extrusion, ndi kuwombera. Kusinthasintha uku, kuphatikiza ndi zina zake, kumapangitsa PP kukhala chisankho chodziwika bwino pamagwiritsidwe osiyanasiyana, kuphatikiza ma CD, zida zamagalimoto, ndi zinthu za ogula.
Ponseponse, ndodo ya PP ndizinthu zosunthika komanso zokhazikika zomwe zimapereka kuphatikiza kwapadera kwakuthupi ndi makina. Malo ake osungunuka kwambiri, kuuma kwapamwamba kwambiri komanso kukana kukankha, komanso kukana kusokonezeka kwa chilengedwe kumapangitsa kukhala chisankho choyenera pa ntchito zosiyanasiyana. Kaya mukuyang'ana chinthu chomwe chingathe kupirira kutentha kwakukulu, kukana kuvala ndi kung'ambika, kapena zonsezi, ndodo ya PP ndi njira yodalirika komanso yodalirika yomwe imakwaniritsa zosowa zanu.
