Amaphepha ePolystyrene

Zithini iishethi ze-polystyrene?

Iishethi zePolystyrene ziishethi zeplastiki eziqinileyo nezikhaphukhaphu ezenziwe ngeemonomers ze-styrene ezenziwe ngepolymer. Zisetyenziswa kakhulu ekupakisheni, ekugqumeni, ekubekeni imiqondiso, nasekuboniseni ngenxa yokuguquguquka kwazo kunye nokulula kokwenziwa kwazo. Ezifumaneka ngobukhulu obahlukeneyo kunye nokugqitywa, iishethi zePolystyrene zisebenza kuzo zombini iinjongo zorhwebo kunye nezemizi-mveliso.

Ziziphi iintlobo eziphambili zeeshiti ze-polystyrene?

Iiphepha zePolystyrene zahlulwe zibe ziintlobo ezimbini: iGeneral Purpose Polystyrene (GPPS) kunye neHigh Impact Polystyrene (HIPS). I-GPPS inika ukucaca okugqwesileyo kunye nokuqina, okwenza ifaneleke ukusetyenziswa okucacileyo. I-HIPS ihlala ixesha elide kwaye ayichaphazeleki, isetyenziswa rhoqo ekupakisheni nasekuboniseni imveliso.

Ziziphi iindlela eziqhelekileyo zokusebenzisa amaphepha e-polystyrene?

Iisheyiti zePolystyrene zisetyenziswa kakhulu kumashishini afana nokupakisha, ukuthengisa, ukwakha, kunye nemisebenzi yezandla. Zisebenza njengezixhobo ezilungileyo kakhulu zokubonisa izinto ezithengiswayo, iimodeli zokwakha, kunye nokugqunywa eludongeni. Ukongeza, zihlala zisetyenziswa kwiinkqubo ze-thermoforming zokwenza iimveliso zeplastiki ezimile okwesimo.

Ngaba amaphepha e-polystyrene afanelekile ukusetyenziswa ngaphandle?

Iiplastiki zePolystyrene azimelani ne-UV ngokwemvelo kwaye zinokonakala xa zichatshazelwa lilanga ixesha elide. Kwiinkqubo zangaphandle, kucetyiswa ukuba zenziwe ngohlobo oluzinzileyo okanye olugqunywe nge-UV. Ngaphandle kokhuseleko, izinto ezisetyenzisiweyo zinokuba buthathaka kwaye zitshintshe umbala ngokuhamba kwexesha.

Ngaba amaphepha e-polystyrene anokuphinda asetyenziswe?

Ewe, amaphepha e-polystyrene angasetyenziswa kwakhona, nangona iindlela zokusebenzisa kwakhona zixhomekeke kwizixhobo zasekuhlaleni. Ziphantsi kwekhowudi ye-resin yeplastiki #6 kwaye zifuna ukucutshungulwa okukhethekileyo. I-polystyrene esetyenziswa kwakhona idla ngokusetyenziswa kwakhona kwizixhobo zokupakisha, kwiimveliso zokukhusela ubushushu, nakwizinto zeofisi.

Ngaba amaphepha e-polystyrene akhuselekile ekunxibelelaneni nokutya?

I-High Impact Polystyrene (iiHIPS) ngokubanzi ithathwa njengekhuselekileyo ekutyeni xa yenziwe ukuze ihlangabezane nemigangatho emiselweyo. Isetyenziswa kakhulu kwiitreyi zokutya, izivatho, kunye nezikhongozeli. Soloko uqinisekisa ukuba le nto ihambelana nemigaqo ye-FDA okanye ye-EU ngaphambi kokuba uyisebenzise ekutyeni.

Uzisika njani iishethi ze-polystyrene?

Amaphepha ePolystyrene angasikwa kusetyenziswa izixhobo ezahlukeneyo ezifana neemela zombane, izixhobo zokusika ucingo ezishushu, okanye izixhobo zokusika nge-laser. Ukuze ufumane imiphetho echanekileyo necocekileyo, ingakumbi kwiiphepha ezityebileyo, kucetyiswa isarha yetafile okanye i-CNC router. Soloko ulandela amanyathelo okhuseleko kwaye usebenzise izixhobo zokukhusela xa usika.

Ngaba ungapenda okanye uprinte kwiimashiti ze-polystyrene?

Ewe, amaphepha e-polystyrene anika ukuprintwa okuhle kakhulu kwaye asetyenziswa kakhulu ekuprinteni kwesikrini nasekuprinteni ngedijithali. Akwamkela uninzi lweepeyinti ezisekwe kwisinyibilikisi kunye ne-acrylic ezilungiselelwe kakuhle umphezulu. Ukuyibeka kakuhle umphezulu ngaphambi kokuba ipeyinti ibonakale kunokuphucula ukunamathela kunye nokuqina.

Ngaba amaphepha e-polystyrene ayamelana neekhemikhali?

I-Polystyrene ibonakalisa ukumelana okuphakathi kweekhemikhali, ingakumbi emanzini, kwiiasidi, nakwii-alcohols. Nangona kunjalo, ayixhathisi kwizinyibilikisi ezifana ne-acetone, ezinokunyibilikisa okanye zitshintshe izinto. Soloko uqinisekisa ukuba iyahambelana neekhemikhali ezithile ngaphambi kokuba uyisebenzise.

Ingakanani imilinganiselo yobushushu enokunyamezelwa ngamashiti e-polystyrene?

Iiphepha zePolystyrene zihlala zikwazi ukumelana namaqondo obushushu aphakathi kwe -40°C ukuya kwi-70°C (-40°F ukuya kwi-158°F). Kumaqondo obushushu aphezulu, izinto zisenokuqala ukugoba, ukuthamba, okanye ukuguquguquka. Azikhuthazwa kwiindawo ezinobushushu obuphezulu okanye ukusetyenziswa okubandakanya amalangatye avulekileyo.
