Amashidi e-polystyrene

Ayini amashidi e-polystyrene?

Amashidi e-polystyrene angamashidi epulasitiki aqinile, alula enziwe ngama-monomers e-styrene afakwe i-polymer. Avame ukusetshenziswa ekupakisheni, ekushiseni, ekuboniseni izimpawu, nasekubumbeni ngenxa yokuguquguquka kwawo kanye nokulula kokwenziwa. Atholakala ngobukhulu obuhlukahlukene kanye nokuqedwa, amashidi e-polystyrene asebenza kokubili ngezinjongo zezentengiselwano kanye nezezimboni.

Yiziphi izinhlobo eziyinhloko zamashidi e-polystyrene?

Amashidi e-polystyrene ahlukaniswe kakhulu ngezinhlobo ezimbili: i-General Purpose Polystyrene (GPPS) kanye ne-High Impact Polystyrene (HIPS). I-GPPS inikeza ukucaca okuhle kakhulu nokuqina, okwenza ifaneleke ukusetshenziswa okusobala. I-HIPS ihlala isikhathi eside futhi imelana nokushayisana, ivame ukusetshenziselwa ukupakisha nokubonisa imikhiqizo.

Yiziphi izindlela ezivamile zokusebenzisa amashidi e-polystyrene?

Amashidi e-polystyrene asetshenziswa kabanzi kuzo zonke izimboni ezifana nokupakisha, ukukhangisa, ukwakha, kanye nemisebenzi yezandla. Asebenza njengezinto ezinhle kakhulu zokubonisa izindawo zokuthengisa, amamodeli ezakhiwo, kanye nokumbozwa kodonga. Ngaphezu kwalokho, avame ukusetshenziswa ezinqubweni zokushisa ukuze kudalwe imikhiqizo yepulasitiki enomumo.

Ingabe amashidi e-polystyrene afanele ukusetshenziswa ngaphandle?

Amashidi e-polystyrene awamelani ne-UV ngokwemvelo futhi angase anciphe uma echayeka elangeni isikhathi eside. Ezinhlelweni zangaphandle, kunconywa izinhlobo eziqiniswe yi-UV noma ezimboziwe. Ngaphandle kokuvikelwa, izinto zingaba buthakathaka futhi zishintshe umbala ngokuhamba kwesikhathi.

Ingabe amashidi e-polystyrene angaphinde asetshenziswe?

Yebo, amashidi e-polystyrene angaphinde asetshenziswe, yize izinketho zokuphinda kusetshenziswe zincike ezindaweni zasendaweni. Awela ngaphansi kwekhodi ye-resin yepulasitiki #6 futhi adinga ukucutshungulwa okukhethekile. I-polystyrene ephinde yasetshenziswa ivame ukusetshenziswa kabusha ezintweni zokupakisha, imikhiqizo yokuvikela ukushisa, kanye nezinto zasehhovisi.

Ingabe amashidi e-polystyrene aphephile ukuthi angathintana nokudla?

I-High Impact Polystyrene (ama-HIPS) ngokuvamile ibhekwa njengephephile ekudleni uma ikhiqizwa ukuze ihlangabezane nezindinganiso zomthetho. Ivame ukusetshenziswa kumathileyi okudla, izivalo, kanye neziqukathi. Njalo qiniseka ukuthi izinto zihambisana nemithetho ye-FDA noma ye-EU ngaphambi kokuyisebenzisa ekusetshenzisweni kokudla.

Ungazisika kanjani izingcezu ze-polystyrene?

Amashidi e-polystyrene angasikwa kusetshenziswa amathuluzi ahlukahlukene njengemimese yokusetshenziswa, izicucu zensimbi ezishisayo, noma izicucu ze-laser. Ukuze uthole imiphetho eqondile nehlanzekile, ikakhulukazi kumashidi amakhulu, kunconywa i-table saw noma i-CNC router. Njalo landela izinyathelo zokuphepha futhi usebenzise izinto zokuzivikela lapho usika.

Ungakwazi yini ukupenda noma ukuphrinta kumashidi e-polystyrene?

Yebo, amashidi e-polystyrene anikeza ukuphrinta okuhle kakhulu futhi asetshenziswa kabanzi ekuphrinteni kwesikrini nasekuphrinteni kwedijithali. Amukela futhi upende oluningi olusekelwe ku-solvent kanye ne-acrylic olunokulungiswa okufanele kwendawo. Ukuhlobisa indawo kusengaphambili kungathuthukisa ukunamathela nokuqina.

Ingabe amashidi e-polystyrene amelana namakhemikhali?

I-Polystyrene ikhombisa ukumelana okulinganiselwe kwamakhemikhali, ikakhulukazi emanzini, kuma-asidi, kanye notshwala. Kodwa-ke, ayimelani nezinyibilikisi ezifana ne-acetone, ezingancibilikisa noma ziguquguquke. Njalo qinisekisa ukuhambisana namakhemikhali athile ngaphambi kokusebenzisa.

Kuyini ukubekezelela izinga lokushisa kwamashidi e-polystyrene?

Amashidi e-polystyrene ngokuvamile angamelana namazinga okushisa aphakathi kuka--40°C kuya ku-70°C (-40°F kuya ku-158°F). Emazingeni okushisa aphezulu, izinto zingase ziqale ukugoba, ukuthamba, noma ukuguquka. Azinconywa ezindaweni ezishisa kakhulu noma ukusetshenziswa okubandakanya amalangabi avulekile.
