Funda okwengeziwe Nge-Plastic Material?I-Pp Plastic - Okuwukuphela Kwepulasitiki Engashiswa Kuhhavini We-Microwave

Sonke siyazi ukuthi ipulasitiki eminingi kulula ukukhulula ama-carcinogens ngemva kokushisa, okuthinta impilo yomuntu, i-polypropylene, ipulasitiki ye-PP iyona engcono kakhulu yokumelana nokushisa epulasitiki emihlanu emikhulu.Isetshenziswa kakhulu ekufakweni kokudla.Ipulasitiki eshiswe nge-oven microwave.

 

I-Polypropylene, ebizwa ngokuthi i-PP ngamafuphi, iyinhlaka yokwenziwa ye-thermoplastic esebenza kahle enezinto eziqinile ezingenambala, ezingenaphunga, ezingenabuthi, ezishintshashintshayo, ukuminyana okuncane nokukhanya: I-PP iwumthamo wepulasitiki owugqinsi kakhulu, enobuningi obungu-0.89 kuphela. ~ 0.91g/cm (okuncane kunamanzi)

Ukumelana nokushisa okuhle: Ngokujwayelekile amapulasitiki, ipulasitiki ye-PP iyona engcono kakhulu yokumelana nokushisa, futhi izinga lokushisa layo le-thermal deformation liyi-80-100 ° C. Ingaphekwa emanzini abilayo.

Ukuqina okuhle: Ipulasitiki ye-PP inokumelana okuhle nokuqhekeka, kanye nempilo yokukhathala ephezulu, okulula ukuyibumba.

Ukumelana namakhemikhali: Ipulasitiki ye-PP ingamelana ne-asidi, i-alkali, isixazululo sikasawoti kanye nezinyibilikisi ezihlukahlukene eziphilayo ezingaphansi kuka-80 ° C, futhi ingabola ngaphansi kwezinga lokushisa eliphezulu nomphumela we-oxidation.

Ngasikhathi sinye, ipulasitiki ye-PP nayo inokufakwa kukagesi, izakhiwo zemishini ezinamandla kakhulu kanye nezakhiwo ezinhle zokucubungula ezigqokekayo.

Ububi bepulasitiki ye-PP: ukunemba kosayizi ophansi, ukuqina okunganele, ukumelana nesimo sezulu esibi, kanye "nokulimala kwethusi".Ine-post-contraction phenomenon.

Njengenye yamapulasitiki amakhulu amahlanu epulasitiki, i-PP Plastic isetshenziswa kabanzi empilweni yansuku zonke:

A. Umkhakha wemboni yezimoto:I-PP enezithako zensimbi: amaphedi, amapayipi okungenisa umoya, abalandeli, njll.

B Impahla Yasekhaya:

C ibhokisi lokugcina elisha

D isiqukathi/idivayisi yokuvala

Njengomkhiqizi wesikoimikhiqizo yepulasitiki kanye nesikhunta, ungahlangabezana nezidingo eziningi eZhongda.Uma unentshisekelo kithi, sicela usithinte nganoma yisiphi isikhathi.
