Polystyrene Expanded: izici, izinzuzo, nebubi

Eminyakeni engaba ngu-ayisithupha edlule, i-material amasha wokwakha ngokuthi polystyrene. Izici ke kude uvelile ngaphambi eziningi aziwa isikhathi ukwahlukanisa. ukuthandwa PPP lakhuphuka e inchubekelembili weJiyomethri. Namuhla, ovulekile futhi adale esihle esisha ngoba nangokuvikela izinto, kodwa PPP, owaziwa kakhulu kithi njengoba Foam (nakuba Foam futhi polystyrene akhiqizwa ngezindlela ezahlukene), namanje omunye the best. Yini kanjalo ukhangwa polystyrene abakhi?

izici Material kanye nezinzuzo

Indlela engcono kakhulu kwagezi - ukushisa ukwahlukanisa kwezindlu. Ukuze "minza mgwaqo" kufanele kube ikhaya elihle efudumele. Indlela elula yokwenza lokhu nge-PPP engabizi kodwa enokwethenjelwa kakhulu. zithutha Plastic, egcwele igesi-, abaqhubi ompofu kakhulu ukushisa. Lokhu kusiza ukuba uyigcine ngaphakathi endlini zonke ukweqisa sezulu. zifudumele ka polystyrene enwetshiwe Futhi ungagwema izindlu kusuka ngokweqile umswakama. PPP akesabi dampness: ngisho ezinsukwini ezimbalwa ngaphansi kwamanzi, cishe engakutholi ezimanzi. Polystyrene Foam, izimfanelo angafaniswa isihlahla zemvelo, kungaba "ukuphefumula." Umhwamuko permeability ke imayelana kuyafana ukuthi amabhodi noma izitini, ngakho ochwepheshe belulekwa ukuba vimbela emizini yalaba izinto kuyinto Foam. PPP akusho ukubola ayinikezi ukhunta, kuba ngokuphelele muffles umsindo, ngakho ingasetshenziswa hhayi nje njengomuntu heater, kodwa futhi njengendlela yisivikelo umsindo. Yini enye engingabuye styrofoam ezithakazelisayo? Izimpawu nemigomo yalo yokuthakwa kwamakhemikhali kuyinto eyinqaba kakhulu. Akazange afikelwe kwesaba umbala, nosawoti, acid (ngaphandle nitric futhi acetic), ngakho-PPP isetshenziswa ukwakhiwa cishe kuyo yonke indawo. Izindleko eliphansi indaba kuhlangene siyohlale sikhona (PPP akusho ubudala, akusho deform ngaphansi kwanoma yiziphi izimo). Uma indlu luphahlekwa usebenzisa PPP, ungakwazi ukukhohlwa ngakho: heater ngeke kudingeke zishintshe. PPP kunhlobo ezahlukene, kodwa ikakhulukazi amathayili adumile styrofoam. Kungaba Ubukhulu ezahlukene (isib 60x120, 50x100), ngakho abakhi Ungakhetha ifomethi, okufaneleyo isebenze. Yiqiniso, i-PPP, kanye nakho konke okunye, enezinto eziningi kahle. Noma kunjalo, mancane kakhulu ukuthi phakathi sebuningini heater ethandwa kakhulu namanje akwaziwa ukuthi polystyrene.

Izici nemibi

• PPP nokwesatshwa-benzene, dichloroethane nezinye yokususa ingcekeza elenkani.
• Indaba ukungena nakwamanye amazwe ngezinye izikhathi ukwenza Burrows igundane noma imigudu: kunjalo futhi kakhulu othanda ukushisa. Okwesabisa away izilwane zingaba usebenzisa amakhemikhali senzelwe zona.
• foam uqobo oluvuthayo. Ukuze kuncishiswe flammability yayo, abakhiqizi namuhla kunezelwa impahla eluhlaza ilangabi retardants - izinto ukuvimbela amandla omlilo. Etholakala nge-PPP usebenzisa incwadi yabo ephawulwe.
• PPP kokucindezelwa is kahle ibekezelelwe, kodwa ngempela enhle. Ubuchwepheshe banamuhla buye basiza ukuxazulula le nkinga. polystyrene extruded Sinemandla kunokuvamile, noma kancane okubi kakhulu ukwedlula maqembu umusi. Kodwa ukuntuleka kahle ukupholisa uhlelo anyamalale.

Ingabe ufuna izinga ezishibhile kodwa ophakeme futhi ikujabulise endlini isikhathi eside? Khetha polystyrene. Awukwazi ukuya engalungile.
