N’chifukwa chiyani mitengo ya nyali za PS ndi PC pamsika ndi yosiyana kwambiri? Lero, ndikudziwitsani za makhalidwe a zipangizo ziwiri.
1. Polystyrene (PS)
• Kapangidwe: Polima yopanda mawonekedwe, Kuchepa pambuyo poumba zosakwana 0.6; kukhuthala kochepa kumapangitsa kuti zotulutsa zikhale zazikulu ndi 20% mpaka 30% kuposa zinthu zonse.
• Ubwino: mtengo wotsika, wowonekera bwino, wopaka utoto, kukula kokhazikika, kulimba kwambiri
• Zoyipa: kugawanika kwakukulu, kukana kusungunuka bwino, kukana kutentha
• Kugwiritsa ntchito: zolembera, zoseweretsa, chivundikiro cha zida zamagetsi, mbale za styrofoam
2. Polycarbonate (PC)
• Katundu: Thermoplastics yopanda mawonekedwe
• Ubwino: mphamvu yayikulu komanso yotanuka, mphamvu yayikulu yogwira ntchito, kutentha kwakukulu kogwirira ntchito, kuwonekera bwino komanso utoto wopanda pake, HDT yayikulu, kukana kutopa bwino, kukana nyengo yabwino, mawonekedwe abwino amagetsi, osakoma komanso opanda fungo, osavulaza thupi la munthu, thanzi ndi chitetezo, kuchepa pang'ono kwa mawonekedwe ndi kukhazikika bwino kwa mawonekedwe.
• Zoyipa: Kapangidwe kolakwika ka zinthu kungayambitse mavuto amkati mwa munthu.
• Kugwiritsa Ntchito:
√ Zamagetsi: ma CD, ma switch, ma housing a zida zapakhomo, mfuti zolumikizirana, mafoni
√ Galimoto: mabampala, mabolodi ogawa, magalasi otetezera
√ Zigawo zamafakitale: makamera, malo osungira makina, zipewa, magalasi oteteza madzi, magalasi oteteza
3. Zochitika zina
• Kutumiza kuwala kwa PS ndi 92%, pomwe kwa PC ndi 88%.
• Kulimba kwa PC kuli bwino kwambiri kuposa PS, PS ndi yofooka ndipo imatha kusweka mosavuta, pomwe PC ndi yolimba kwambiri.
• Kutentha kwa kutentha kwa PC kumafika madigiri 120, pomwe PS ndi madigiri 85 okha.
• Kusinthasintha kwa zinthu ziwirizi nakonso n'kosiyana kwambiri. Kusinthasintha kwa PS n'kwabwino kuposa kwa PC. PS ingagwiritse ntchito zipata za point, pomwe PC imafuna chipata chachikulu.
• Mtengo wa ziwirizi ndi wosiyana kwambiri. TsopanowabwinobwinoMtengo wa PC ndi woposa mayuan 20, pomwe mtengo wa PS ndi mayuan 11 okha.
PS pulasitiki imatanthauza ClassⅠplastic yomwe imaphatikizapo Styrene mu unyolo wa Macromolecular, komanso imaphatikizapo Styrene ndi Copolymers. Imasungunuka mu Aromatic hydrocarbons, Chlorinated hydrocarbons, Aliphatic Ketones ndi esters, koma imatha kuphulika mu acetone yokha.
PC imatchedwanso Polycarbonate, chidule chake ndi PC, ndi chinthu chopanda utoto, chowonekera, komanso chosapanga mawonekedwe a thermoplastic. Dzinali limachokera ku gulu la Internal CO3.
Ndikukhulupirira kuti izi zingathandize makasitomala kumvetsetsa chifukwa chake pali kusiyana kwa mitengo pakati pa PC ndi PS. Ndikukhulupiriranso kuti makasitomala azikhala otseguka posankha nyali, musanyengedwe ndi mtengo. Kupatula apo, mumapeza zomwe mumalipira.
Monga kampani yopanga magetsi ya Liper, timasamala kwambiri posankha zinthu, kotero mutha kusankha ndikugwiritsa ntchito molimba mtima.
