Kodi pali kusiyana kotani pakati pa pulasitiki PS ndi PC?

Chifukwa chiyani mitengo ya nyali za PS ndi PC pamsika ndizosiyana kwambiri?Lero, ndikuwonetsa mawonekedwe azinthu ziwiri.

Chifukwa chiyani mitengo ya nyali za PS ndi PC pamsika ndizosiyana kwambiri?Lero, ndikuwonetsa mawonekedwe azinthu ziwiri.

1. Polystyrene (PS)

• Katundu: Amorphous polima, Shrinkage pambuyo poumba zosakwana 0.6;otsika kachulukidwe linanena bungwe 20% mpaka 30% kuposa zinthu wamba

• Ubwino: mtengo wotsika, wowonekera, wonyezimira, wosasunthika, wosasunthika kwambiri

• Zoipa: kugawanika kwakukulu, kusagwirizana kwa zosungunulira, kukana kutentha

• Ntchito: zolembera, zoseweretsa, chotengera chamagetsi chamagetsi, styrofoam tableware

2. Polycarbonate (PC)

• Katundu: Amorphous thermoplastics

• Ubwino: kulimba kwambiri ndi zotanuka modulus, mphamvu yamphamvu kwambiri, kutentha kosiyanasiyana kogwiritsa ntchito, kuwonekera kwambiri komanso utoto waulere, HDT yapamwamba, kukana kutopa kwabwino, kukana nyengo yabwino, mawonekedwe abwino kwambiri amagetsi, osakoma komanso osanunkhiza, osavulaza thupi la munthu, thanzi. ndi chitetezo, otsika akamaumbidwe shrinkage ndi wabwino dimensional bata

• Zoipa: Kusapanga bwino kwa mankhwala kungayambitse mosavuta mavuto amkati

• Ntchito:

√ Zamagetsi: ma CD, masiwichi, nyumba zopangira zida zapanyumba, mizinga yamawu, mafoni

√ Galimoto: mabampa, matabwa ogawa, galasi lachitetezo

√ Zigawo za mafakitale: matupi a kamera, nyumba zamakina, zipewa, magalasi osambira, magalasi otetezera

3. Zochitika zina

• Kuwala kwa PS ndi 92%, pamene kwa PC ndi 88%.

• Kulimba kwa PC kuli bwino kwambiri kuposa PS, PS ndi yolimba ndipo imatha kusweka mosavuta, pomwe PC imakhala yolimba.

• Kutentha kwa kutentha kwa PC kumafika madigiri 120, pamene PS ndi pafupifupi madigiri 85 okha.

• Madzi amadzimadzi awiriwa ndi osiyana kwambiri.The fluidity ya PS ndiyabwino kuposa PC.PS imatha kugwiritsa ntchito zipata zakumalo, pomwe PC imafunikira chipata chachikulu.

• Mtengo wa awiriwo ndi wosiyana kwambiri.TsopanozabwinobwinoPC imawononga ndalama zoposa 20 yuan, pomwe PS imawononga yuan 11 yokha.

Pulasitiki ya PS imatanthawuza ClassⅠpulasitiki yomwe imaphatikizapo Styrene mu unyolo wa Macromolecular, ndikuphatikizanso Styrene ndi Copolymers.Amasungunuka mu ma hydrocarboni onunkhira, ma chlorinated hydrocarbons, Aliphatic Ketones ndi esters, koma amangotupa mu acetone.

PC imatchedwanso Polycarbonate, yofupikitsidwa ngati PC, ndi zinthu zopanda mtundu, zowonekera, za amorphous thermoplastic.Dzinali limachokera ku gulu la Internal CO3.

Ndikukhulupirira kuti zitha kuthandiza makasitomala kumvetsetsa chifukwa chake pali kusiyana kwamitengo pakati pa PC ndi PS.Ndikukhulupiriranso kuti makasitomala azikhala otseguka posankha nyali, musapusitsidwe ndi mtengo wake.Pambuyo pake, mumapeza zomwe mumalipira.

Liper monga katswiri wopanga zowunikira, ndife okhwima kwambiri pakusankha zinthu, kotero mutha kusankha ndikuzigwiritsa ntchito molimba mtima.
