Xaashiyaha polystyrene

Waa maxay xaashida polystyrene?

Waraaqaha polystyrene waa kuwo adag, balaastig ah oo khafiif ah oo laga sameeyay monomers styrene polymerized. Caadi ahaan waxaa loo isticmaalaa baakadaha, dahaarka, calaamadaynta, iyo qaabaynta iyadoo ay ugu wacan tahay kala duwanaanshahooda iyo sahlanaanta wax-soo-saarka. Waxaa lagu heli karaa dhumucyo kala duwan iyo dhameystir, xaashida polystyrene waxay u adeegtaa ujeedooyin ganacsi iyo mid warshadeed labadaba.

Waa maxay noocyada ugu muhiimsan ee xaashida polystyrene?

Waraaqaha polystyrene ayaa marka hore loo kala saaraa laba nooc: Ujeedada Guud ee Polystyrene (GPPS) iyo Polystyrene Saamaynta Sare (HIPS). GPPS waxay bixisaa hufnaan iyo qallafsanaan aad u wanaagsan, taasoo ka dhigaysa mid ku habboon codsiyada daah-furnaanta ah. HIPS waa mid aad u waara oo u adkaysata saamaynta, oo inta badan loo isticmaalo baakadaha iyo bandhigyada alaabta.

Waa maxay codsiyada caadiga ah ee xaashida polystyrene?

Waraaqaha polystyrene ayaa si weyn loogu isticmaalaa warshadaha sida baakadaha, xayeysiinta, dhismaha, iyo farsamada gacanta. Waxay u adeegaan sidii qalab aad u fiican oo loogu talagalay bandhigyada goobta-iibka, moodooyinka qaab dhismeedka, iyo xidhitaanka gidaarka. Intaa waxaa dheer, waxaa inta badan loo isticmaalaa hababka heerkulbeegga si loo abuuro badeecooyin qaabaysan.

Go'yaal polystyrene ah ma ku habboon yihiin isticmaalka dibadda?

Waraaqaha polystyrene maaha kuwo u adkaysta UV waxaana laga yaabaa inay hoos u dhacaan soo-gaadhista iftiinka qorraxda ee dheer. Codsiyada dibadda, noocyada UV-dejiyay ama dahaarka leh ayaa lagula talinayaa. Ilaalin la'aan, maaddadu waxay noqon kartaa mid jajaban oo midabkeedu waqti ka dib.

Ma dib loo warshadayn karaa xaashida polystyrene?

Haa, xaashida polystyrene waa dib loo warshadayn karaa, inkasta oo doorashooyinka dib u warshadaynta ay ku xidhan yihiin tas-hiilaadka deegaanka. Waxay ku hoos dhacaan resin code #6 waxayna u baahan yihiin habayn gaar ah. Polystyrene dib loo warshadeeyay ayaa inta badan dib loogu isticmaalaa agabka baakadaha, alaabta dahaarka, iyo sahayda xafiiska.

Xaashiyaha polystyrene ammaan ma u yihiin cunnada?

Saamaynta Sare ee Polystyrene (HIPS) ayaa guud ahaan loo arkaa cunto-ammaan ah marka la soo saaro si loo buuxiyo heerarka sharciga. Waxaa caadi ahaan loo isticmaalaa saxarada cuntada, daboolka, iyo weelasha. Had iyo jeer hubi in alaabtu u hoggaansanto FDA ama xeerarka EU ka hor inta aanad u isticmaalin codsiyada cuntada.

Sideed u gooysaa xaashida polystyrene?

Go'yaasha polystyrene waa la gooyn karaa iyadoo la isticmaalayo qalabyo kala duwan sida mindiyaha tamarta, xargaha kulul, ama jarista laysarka. Cidhifyada saxda ah iyo kuwa nadiifka ah, gaar ahaan go'yaal dhumuc weyn, miis miinshaar ama router CNC ayaa lagula talinayaa. Had iyo jeer raac taxaddarrada badbaadada oo isticmaal qalabka ilaalinta markaad gooynayso.

Ma ku rinjin kartaa ama ku daabacan kartaa go'yaal polystyrene?

Haa, xaashida polystyrene waxay bixiyaan daabacaad heer sare ah waxaana si weyn loogu isticmaalaa daabacaadda shaashadda iyo daabacaadda dhijitaalka ah. Waxay sidoo kale aqbalaan inta badan rinjiga ku salaysan dareeraha iyo akriliga leh diyaarinta saxda ah ee dusha sare. Sare u qaadista dusha ka hor waxay kor u qaadi kartaa adhesion iyo adkeysiga.

Waraaqaha polystyrene ma yihiin kuwo u adkaysta kiimikooyinka?

Polystyrene waxay muujisaa iska caabin dhexdhexaad ah oo kiimiko ah, gaar ahaan biyaha, asiidhka, iyo alkolada. Si kastaba ha ahaatee, ma aha mid u adkaysata dareerayaasha sida acetone, kaas oo milmi kara ama wax u dhimi kara walxaha. Had iyo jeer hubi in ay la socdaan kiimikooyin gaar ah ka hor codsiga.

Waa maxay dulqaadka heerkulka xaashida polystyrene?

Xaashiyaha polystyrene waxay caadi ahaan u adkeysan karaan heerkulka u dhexeeya -40°C ilaa 70°C (-40°F ilaa 158°F). Heerkulka sare, maaddadu waxay bilaabi kartaa inay galooto, jilciso, ama qallafsanto. Laguma talinayo jawi kuleyl sare leh ama codsiyada ku lug leh ololka furan.
