Sei mitengo yemwenje yePS nePC iri pamusika yakasiyana kudaro? Nhasi, ndichakuratidza hunhu hwezvinhu zviviri izvi.
1. Polystyrene (PS)
• Hunhu: Amorphous polymer, Kuoma kwechinhu mushure mekuumbwa kusingasviki 0.6; density yakaderera inoita kuti chinhu chibudiswe ne20% kusvika 30% kupfuura zvinhu zvese.
• Zvakanakira: mutengo wakaderera, unoonekera, unodhayiwa, saizi yakatarwa, kuomarara kwakanyanya
• Zvakaipa: kupatsanuka kwakanyanya, kusasimba kwe solvent, kusasimba kwekupisa
• Mashandisirwo: zvinhu zvekushandisa, matoyi, keji yemidziyo yemagetsi, tafura yestyrofoam
2. Polycarbonate (PC)
• Hunhu: Thermoplastics isina chimiro
• Zvakanakira: simba rayo guru uye elastic modulus, simba rayo guru, tembiricha yayo inoshanda zvakasiyana-siyana, kujeka kwayo kwakanyanya uye kudhaya pasina muripo, HDT yakawanda, kuramba kuneta kwakanaka, kuramba mamiriro ekunze akanaka, hunhu hwemagetsi hwakanaka, kunaka kwazvo, kunaka kwayo uye kunhuwa kwayo, kusakuvadza muviri wemunhu, hutano nekuchengetedzeka, kuderera kwechimiro uye kugadzikana kwayo.
• Zvakaipa: Kusagadzirwa zvakanaka kwechigadzirwa kunogona kukonzera matambudziko emukati memuviri
• Kushandiswa:
√ Zvemagetsi: maCD, maswichi, dzimba dzemidziyo yepamba, mabhomba ezviratidzo, nharembozha
√ Mota: mabumpers, mabhodhi ekuparadzira, magirazi ekuchengetedza
√ Zvikamu zvemaindasitiri: makamera, dzimba dzemuchina, ngowani, magogorosi ekunyudza, magirazi ekuchengetedza
3. Mamwe mamiriro ezvinhu
• Kutumira chiedza kwePS i92%, ukuwo kuPC i88%.
• Kusimba kwePC kuri nani pane PS, PS inogwamba uye inogona kutyoka zviri nyore, ukuwo PC inotsungirira zviri nani.
• Tembiricha yekushanduka kwekupisa kwePC inosvika madhigirii zana nemakumi maviri, nepo PS iri madhigirii makumi masere nemashanu chete.
• Kuyerera kwezviviri izvi kwakasiyanawo zvikuru. Kuyerera kwePS kuri nani pane kwePC. PS inogona kushandisa magate epoint, nepo PC ichida geti hombe.
• Mutengo wezviviri wakasiyanawo zvikuru. Iye zvinozvakajairikaPC inodhura mari inodarika mayuan makumi maviri, ukuwo PS ichidhura mayuan gumi nerimwe chete.
PS plastic inoreva ClassⅠplastic inosanganisira Styrene muMacromolecular chain, uye inosanganisirawo Styrene neCopolymers. Inonyungudika muAromatic hydrocarbons, Chlorinated hydrocarbons, Aliphatic Ketones uye esters, asi inogona kuzvimba muacetone chete.
PC inonziwo Polycarbonate, kana ichipfupikiswa sePC, chinhu chisina ruvara, chinoonekera, chisina chimiro chethermoplastic. Zita racho rinobva kuboka reInternal CO3.
Ndinovimba kuti zvinogona kubatsira vatengi kunzwisisa kuti sei paine musiyano wemitengo pakati pePC nePS. Ndinovimbawo kuti vatengi vacharamba vakasvinura pavanosarudza marambi, musanyengerwa nemutengo. Pamusoro pezvose, munowana zvamunobhadhara.
Semugadziri wemwenje wehunyanzvi, Liper, tine hungwaru pakusarudza zvinhu, saka unogona kusarudza nekuishandisa nechivimbo.
