Kutanga, ngatitangei kuziva zvinhu zviviri izvi:

Chii chinonzi PC material?

Muindasitiri, polycarbonate (Polycarbonate) inonzi PC. Muchokwadi, PC zvinhu ndeimwe yemapurasitiki edu akagadzirwa. Chikonzero nei ichishandiswa zvakanyanya mukugadzira inotemwa nehunhu hwayo. PC ine yakasarudzika mabhenefiti ekusapisa moto, isiri-chepfu uye ine ruvara. Chinokosha ndechekuti ine simba guru rekuwedzera, tembiricha yakakwira uye yakaderera-tembiricha kuramba, uye yakanaka extensibility. Chinokosha ndechekuti hutano hwechigadzirwa chakapedzwa hwakanaka. Idzi dzave sarudzo yefenicha yakawanda yekusarudza PC seyakagadzirwa. Chikonzero chakakosha.

Chii chinonzi PP zvinhu?

PP ndiyo chidimbu chepolypropylene (Polypropylene), uye zvakare ndiyo yatinowanzo kudaidza kuti Fold-fold plastic, inovawo mhando yepurasitiki yekugadzira maindasitiri. PP chigadzirwa chepurasitiki chekugadzira, asi inewo zvayakanakira nezvayakaipira. Mabhodhoro mazhinji evacheche anozogadzirwa nePP zvinhu nekuti inoshingirira kune tembiricha yakanyanya uye yakanyatsonaka kupfuura 100 madhigirii Celsius, saka inokodzera zvinodiwa zvekugara uchifashaira mvura yekuuraya hutachiona hwemabhodhoro evana. Kugadzikana kwePP kwakanaka.

Saka nei muindasitiri yefenicha, izvo zvePC zvinotsiviwa zvishoma nezvishoma nePP zvinhu? Zvikonzero ndezvizvi:

Cost factor

Mutengo wekutenga zvinhu zvePC resin wakakwira zvakanyanya kupfuura wePP. Iyo yakaipisisa mbishi yePC inodarika zviuru makumi maviri patani, uye iyo yakabikwa mutengo wePP i10,000. PP zvakare ndeimwe yeanonyanya kushandiswa mapurojekiti.

Fashoni pfungwa

Panyaya yekufambiswa kwechiedza kwemapurasitiki, PC resin inokunda. PC ndeimwe yeatatu mapurasitiki akajeka ane yakanakisa mwenje transmittance. Iyo yakapedzwa fenicha yakajeka uye isina ruvara. Kupinda kwe pp kwakashata kwazvo, uye PP yakajairwa ine hutsinye hwekunzwa kwemhute, iyo inopfumisa magadzirirwo echinhu uye inoita kuti ruvara ruwedzere matte, izvo zvinoita kuti iwedzere mberi. Sarudzo yemavara akawanda yakavewo yaidiwa nayo. Zvikonzero zvekugamuchirwa. Sarudzo dzakapfuma, kwete imwechete sePC zvinhu.

Hunhu hwezvinhu

Kuoma uye kuoma kwemapurasitiki maviri aya akasiyana. PC ine kuomarara kwakanyanya, PP ine kuomarara kwakadzika patembiricha yekamuri, uye inogona kuremara nyore nyore uye kukotama nechisimba chekunze. Nekudaro, PP ine kusimba kwakanaka kwazvo, inowanzozivikanwa seBaizhe glue, uye inoshandiswa zvakanyanya mufenicha. Kuomarara kwayo kunoita kuti iwedzere kusimba uye ine zviri nani kutakura mutoro.

Manufacturability

Iyo fluidity yePP jekiseni yakanaka kwazvo uye iri nyore kuumba, nepo fluidity yePC yakashata uye zvakaoma kufambisa glue. Uye zvakare, PC iri nyore kuora uye kushandura ruvara pakupisa kwakanyanya mukuumbwa kwejekiseni, uye jekiseni kuumba kunoda yakagadziridzwa PC sikuru. Saka muchokwadi, mutengo wekugadzirisa wezvigadzirwa zvePC wakakwira. Panguva imwecheteyo, kana zvigadzirwa zvemajekiseni ePC zvichigadzirwa, nekuda kwehunhu hwavo hwakajeka uye nyore kuona mabhuru uye kusvibiswa mukati, goho rakaderera zvakanyanya. Kana iri musika wepamusoro-soro, zvakaoma zvikuru kudzora kunaka kwezvigadzirwa zvePC, izvo zvinowedzerawo zvakanyanya mari yekugadzira.

Safety factor

Zvigadzirwa zvePC zvinogona kuora bisphenol A, izvo zvinokuvadza kuhutano hwevanhu. PC tembiricha yepamusoro haiburitse bisphenol A, asi bisphenol A ndiyo mbishi yekugadzira mapurasitiki ePC. Mushure mekugadzirwa kwebisphenol A, PC inogadzirwa. Mushure mekugadzirwa kwemakemikari, bisphenol A yepakutanga haisisipo. Kungoti iyi synthesis process inzira, uye pane kutsauswa mukuita, zvinonetsa kuti 100% izere kuita, uye panogona kunge paine yasara bisphenol A (pamwe). Kana PC ikasangana nekupisa kwakanyanya, zvinokonzeresa kuti bisphenol A ibude mupurasitiki. Naizvozvo, kana muine bisphenol A yasara, kunaya kwemvura inopisa uye kunaya kwechando kuchavapo, uye kunaya kwechando kunononoka.

Zvose mune zvose, kushanda kwePC nePP kwakasiyana, uye hazvibviri kungoziva kuti ndiani akanaka uye ndiani akaipa. Izvo zvichiri kudikanwa kusarudza chakanakisa chigadzirwa chechikamu chekushandisa. Uye PP inonyanya kushandiswa mumunda wefenicha, ndosaka PP fenicha iri kutsiva PC fenicha zvishoma nezvishoma.
