1. Izinto ezahlukeneyo
Iisutikheyisi zePPzizinto ze-polypropylene resins.Ngenxa yokuba i-homopolymer PP i-brittle kakhulu xa ubushushu bungaphezulu kwe-0C, izixhobo ezininzi ze-PP zorhwebo zi-copolymers ezingahleliwe kunye ne-1 ~ 4% ye-ethylene eyongeziweyo okanye i-clamps enomxholo ophezulu we-ethylene.ifomula copolymer.
I-PC kwisutikheyisi yePC ibizwa ngokuba yi "polycarbonate".I-Polycarbonate yintlaka eqinile ye-thermoplastic efumana igama layo kumaqela e-CO3 ngaphakathi kuyo.Nge-bisphenol A kunye ne-carbon oxychloride synthesis.Eyona ndlela isetyenziswa kakhulu yi melt transesterification method (ibisphenol A kunye ne diphenyl carbonate zenziwe nge transesterification kunye ne polycondensation).
2. Iimpawu ezahlukeneyo
I-suitcase ye-PP: Isixhobo se-PP sohlobo lwe-copolymer sineqondo lokushisa eliphantsi lokuguqula i-thermal (100C), ukukhanya okuphantsi, i-gloss ephantsi, ubulukhuni obuphantsi, kodwa inamandla eempembelelo ezinamandla.Amandla e-PP ayanda ngokunyusa umxholo we-ethylene.Iqondo lokushisa le-Vicat lokuthambisa le-PP yi-150C.Ngenxa yezinga eliphezulu le-crystallinity, le nto inobunzima obuhle bomgangatho kunye neempawu zokumelana nokuqala.
PC suitcase: I-resin ye-amorphous thermoplastic eneempawu ezigqwesileyo ezibanzi, kunye ne-insulation yombane egqwesileyo, i-elongation, i-dimensional stability kunye nokumelana neekhemikhali, amandla aphezulu, ukumelana nobushushu kunye nokumelana nokubanda;Ukwanayo nokuzicima, ukunqanda umlilo, okungeyotyhefu, okunemibala, njl.
3. Amandla ahlukeneyo
Isuitcase yePP: inamandla efuthe elinamandla.Ukuqina komphezulu kunye neepropathi zokumelana nokukrala kwesi sixhobo zibalaseleyo.
I-PC suitcase: Amandla ayo anokwanelisa iimfuno ezahlukeneyo ukusuka kwiifowuni eziphathwayo ukuya kwiglasi engangenwa bulletproof.Xa kuthelekiswa nesinyithi, ukuqina kwayo akwanelanga, okwenza ukuba ukubonakala kwayo kube lula ukukrazula, kodwa amandla kunye nokuqina kwayo kuhle kakhulu, nokuba ingcinezelo enzima okanye ngokubanzi , ngokude nje ungazami ukuyishukumisa, ide ngokwaneleyo.
