Uthini umahluko phakathi kwekomityi yeplastiki ye-pc kunye ne-pp yeplastiki yekomityi

ikomityi yeplastiki ye-pc ibhekisa kwikomityi yeplastiki eyenziwe ngezinto ze-polycarbonate, inani elisezantsi ngu-7;i-pp yeplastiki yekomityi ibhekiselele kwikomityi yeplastiki eyenziwe nge-polypropylene, inani elisezantsi ngu-5. ikomityi yeplastiki ye-pc kunye ne-pp yeplastiki yekomityi umahluko kakhulu inezi ngongoma zilandelayo:

1, PC impahla yeplastiki ikomityi transmittance ilungile, kwaye ukukhanya ngaphezu kweglasi, ixabiso eliphantsi, PC impahla yeplastiki ikomityi inokumelana -30 ℃ ~ 140 ℃ lobushushu, sitsho nje ukuba le nto kule ubushushu ayiqhekezi, ukunyibilika.

I-2, ikomityi yeplastiki yezinto zePP ilula kakhulu, akukho lula ukuyiqhekeza;Ukumelana nokushisa okulungileyo, ngokungathandabuzekiyo kwezinto ezinobuthi, ezinzile kwaye zikhuselekile;Ukungalungi kokuhanjiswa kokukhanya kumbi kancinci.

I-3, ukuqina kwePC yeplastiki kuphezulu kunobulukhuni beplastiki ye-PP yendalo yonke, imathiriyeli ye-PP eluhlaza i-translucent milky emhlophe, i-PC ekrwada iyabonakala.I-PP ikwabizwa ngokuba bubulukhuni berabha ephindiweyo bungcono, iPC ikwabizwa ngokuba bubulukhuni berabha yerabha engangembumbulu kunye namandla empembelelo aphezulu kakhulu.

I-4, i-PP yiplastiki eqhelekileyo, ubuninzi be-PP bungaphantsi kwe-1.0cm / g, i-PP idada emanzini;I-PC yiplastiki yobunjineli, ubuninzi bePC bungaphezulu kwe-1.0cm/g, iPC intywiliselwe emanzini.

I-5, i-PC impahla yeplastiki indebe emva kokufudumeza ngokuphindaphindiweyo iya kuvelisa i-bisphenol -A kunye nezinye i-carcinogens, i-PP indebe yeplastiki ayiyi .

ikomityi yeplastiki ye-pc kunye ne-pp yeplastiki yekomityi zixhaphake iindidi ezimbini zekomityi yamanzi yeplastiki, umahluko omkhulu phakathi kwezi zimbini kukuba ikomityi yeplastiki ye-pc ayinakugcwaliswa ngamanzi abilayo kunye ne-pp yeplastiki yekomityi inokuzaliswa ngamanzi abilayo.Ukongeza, ezi zimbini ekuxhathiseni ubushushu, ubulukhuni, ukuxinana kunye neminye imiba inomahluko othile.ikomityi yeplastiki ye-pc ngenxa yokumelana nobushushu obuphantsi, equkethe amanzi abilayo okanye ukukhululwa kwezinto ze-bisphenol, ingozi kwimpilo yabantu, ngoko ayinakusetyenziswa ukuzalisa amanzi abilayo;I-pp impahla yeplastiki ikomityi ezaliswe ngamanzi abilayo ayinayo ityhefu, kwaye ukumelana nobushushu obuphezulu kunamandla.
