I-polystyrene ene-foamed. Uthini?

I-polystyrene enezinyosi ivele phakathi nekhulu lama-20. Yenziwe ngamapelitiki e-polystyrene akhiqizwa ngesikhathi kusetshenzwa amafutha. Ngakho-ke, i-polystyrene inezizathu eziphilayo. Into emangalisa kakhulu ukuthi lokhu kutholakala ngisho nokudla okunjengokweshizi, isitibhele, isinamoni, iwayini kanye nabanye. I-Polystyrene ibhekwa njengeyena enobuhlungu futhi engathathi hlangothi eziphilayo eziphilayo. Lokhu kusho ukuthi lezinto azikwazi ukulimaza abantu futhi zingasetshenziswa ezindaweni ezihlukahlukene zomsebenzi wesintu.

I-polystyrene ene-foam ishicilelwa ngokugcoba nokukhwabanisa ubuhlalu be-polystyrene. Ama-granules agonywa nge-pentane (lokhu kuyimfucumfucu yegesi yemvelo) kanye nokufudumala kwe-steam ngesikhathi esisodwa. Ngenxa yalokho, i-granule yanda cishe izikhathi ezingu-50, iphenduka ibhaluni eligcwele umoya. Leli bhola likhulu kakhulu futhi lizinzile, futhi inqubo ehlanekezelayo, okungukuthi, "ukuqhuma," akuveli. Ngakho-ke i-polystyrene foams etholakalayo iyasondwa yi-steam. Kutholakala impahla ehambisanayo. Izinqubo zokugcoba nokukhwabanisa zikanyekanyekanye.

Ngeshwa, eRussia ukukhiqizwa kwe-polystyrene kwenzeka ngokusetshenziswa kobuchwepheshe obungapheli. Ibizwa ngokuthi "indlela yokumisa ukukhishwa kwe-styrene phambi kwe-generator ye-steam." Ngenkathi imboni yomhlaba isebenzisa indlela yokupholisa okuqhubekayo ngobuningi. Le ndlela yenza kube lula ukuthola impahla yekhwalithi ephezulu ngezindleko eziphansi.

I-polystyrene ene-Foamed ingaba yi-100% emoyeni. Akuqukethe amakhemikhali engeziwe. Lezi zinto ziqinile kakhulu, aziwa phansi ngaphansi kwethonya lemvelo. Ngakho-ke, lisetshenziselwa ukusebenza ekwakhiweni. Njengoba polystyrene ine conductivity okuhle ezishisayo, cishe ayidluli umswakama, akuyona eyingozi empilweni yabantu kanye nemvelo.

Ukwakhiwa kwe-polystyrene eneziphukuphuku kuyasetshenziswa njenge-heater. Isibonelo, ipulatifomu ye-polystyrene enobukhulu obuyizingamamitha angu-12 ithatha udonga olwenziwe ngokhuni olunamamitha angu-45 noma ubude bamamitha amabili!

Ubuchwepheshe bokufakelwa okushisa kwezindonga ngamapulangwe e-polystyrene kulula. Zihlanganiswe emhlabathini ngeglue ekhethekile. Amajoyina amandla phakathi kwamapuleti aqiniswa amathaya ane-bonnet ebanzi eplastiki. Umshini wokushisa unamathele emgodini, okuvimbela ukubukeka kwemifantu nokubola. Isakhiwo sihlanganiswa futhi ngesisombululo seglue. Bese kulandela ukuqedela nge-plaster okuhlobisa noma ezinye izinto.

Kulula kakhulu ukuthenga i-polystyrene enwetshiwe. Kungenziwa kukhethwe kunoma yisiphi isitolo sokwakha. Kuyinto eshibhile kunezinye izinto zokuqapha. Ekuthengeni kubalulekile ukuchazwa, yikuphi ngempela i-polystyrene edingekayo. Kungaba ngezinhlobo ezimbili - ukufudumala izindonga nokufudumala phansi. Owokuqala awunzima njengesibili. Kukhona umehluko phakathi kwe-polystyrene nobukhulu beshidi - kusuka ku-20 mm ukuya ku-120 mm. Ukuzikhethela kuxhomeke emsebenzini ohlongozwayo. Ngokuvamile, ukufudumala kwezindonga esimweni sethu sezulu ngesilinganiso sobude obujwayelekile, i-polystyrene enobukhulu obuyi-50 mm yanele. Uma isakhiwo esinamabhande amancane, i-polystyrene kufanele ibe yimbi. Umthetho ofanayo usebenza ekukhethweni kokukhethwa kokufakwa kokufaka phansi.
