Sonke siyazi ukuba iplastiki eninzi ilula ukukhupha i-carcinogens emva kokufudumeza, echaphazela impilo yabantu, i-polypropylene, iplastiki ye-PP yeyona nto ingcono yokuxhathisa i-thermal kwiiplastiki ezinkulu ezintlanu.Isetyenziswa kakhulu kwipakethe yokutya.Iplastiki ifudunyezwe nge-oven microwave.
I-Polypropylene, ebizwa ngokuba yi-PP ngokufutshane, yintlaka eyenziwe kakuhle ye-thermoplastic enezinto eziqinileyo ezingenambala, ezingenavumba, ezingenatyhefu, eziguquguqukayo, uxinano oluncinci kunye nokukhanya: I-PP yeyona nto inxinaniswayo yeplastiki ekrwada, enoxinano lwe-0.89 kuphela. ~ 0.91g/cm (incinci kunamanzi)
Ukumelana nobushushu obuhle: Ngokubanzi iiplastiki, iplastiki yePP yeyona nto ingcono yokuxhathisa ukushisa, kunye nokushisa kwayo kwe-thermal deformation yi-80-100 ° C. Inokupheka emanzini abilayo.
Ukuqina okuhle: Iplastiki yePP inokumelana kakuhle nokuqhekeka, kunye nobomi bokudinwa okugoba okuphezulu, okulula ukubunjwa.
Ukumelana nemichiza: Iplastiki ye-PP inokumelana ne-asidi, i-alkali, isisombululo setyuwa kunye nezinyibilikisi ezahlukeneyo zezinto eziphilayo ezingaphantsi kwe-80 ° C, kwaye zinokubola phantsi kobushushu obuphezulu kunye nefuthe le-oxidation.
Kwangaxeshanye, iplastiki yePP ikwanazo zokugquma kombane, iipropathi zoomatshini bokuqina obuphezulu kunye nezinto ezilungileyo zokunxiba ezixhathisayo.
Ukungalungi kweplastiki yePP: ukuchaneka kobungakanani obuphantsi, ukungonelanga kokuqina, ukumelana nemozulu embi, kunye "nokulimala kobhedu".Inento ye-post-contraction phenomenon.
Njengenye yeeplastiki ezinkulu ezintlanu zeplastiki, iPlastiki yePP isetyenziswa kakhulu kubomi bemihla ngemihla:
A. Indawo yoshishino lweemoto:I-PP enezongezo zetsimbi: iipads, iipayipi zokungenisa umoya, abalandeli, njl.
B Ifanitshala yeKhaya:
C ibhokisi yokugcina entsha
D isikhongozeli/isixhobo sokutywina
Njengomvelisi wesikoiimveliso zeplastiki kunye nokubumba, ungahlangabezana neemfuno ezininzi e Zhongda.Ukuba unomdla kuthi, nceda uqhagamshelane nathi nangaliphi na ixesha.
