Iningi labathengi licabanga ngale nkinga: Foam noma i-polystyrere Foam, yini okungcono ukufaka isicelo sokufakelwa kanye nokufakwa okuzwakalayo? Abanye baze bakholelwe ukuthi kungokwezinto ezifanayo.
Leli qiniso liqinisekisa imininingwane kwi-Intanethi. Ngokunokwenzeka, lokhu kwenzeka ngenxa yokuthi zenziwe nge-polystyrene, kodwa ngendlela ecophelela ukuthi ubona ukuthi umehluko usatholakala.
Umehluko we-foam ne-polystyrene
Lapho ucubungula ama-polystyrere pellets, umusi owomile uphenduka igwebu
Umehluko omkhulu phakathi kwalezi zinto ezikulandelayo:
- Kubuchwepheshe bokukhiqiza balawa masampula kunomehluko omkhulu. I-Polyfoam yenziwa kusetshenziswa ukucutshungulwa kwama-polystyrere pellets ngomusi owomile. Ukunwebeka ngaphansi kwethonya lokushisa, baqinisa ngokuqinile ngomunye nomunye, ngalesi sikhathi ama-mispopores akhiwa. I-Polystyrere Foam noma iPenlexpl – Leli igama lakhe lokuhweba, elikhiqizwa yindlela "yokukhishwa". Ama-polystyrene granules ancibilika kuzo zombili lezi zimo, kwakhiwa izibopho zamangqamuzana, kwenzeka isakhiwo esisodwa.
- Kukhona nomehluko phakathi kwezimpawu zomzimba nezobuchwepheshe ngenxa yobuchwepheshe bokukhiqizwa kwabo. Uma sikhuluma ngokunganana iqiniso, kwandiswa i-polystyrere ezimpawu ezihlukile kuphakeme kunegwebu.
Umehluko wezindawo ezisebenzayo ngokusebenza okushisayo
Ukuthuthuka okusebenzayo okusebenzayo, okuncane kungaba yinto ebonakalayo
Yini engcono ukufaka isicelo sokufakwa kwe-insulation - i-polystyrere Foam noma igwebu?
Ukuhlaziya amandla wezinto zokwakha ezibhekwayo, umehluko wazo ungaphawulwa.
Isici esiyinhloko sokufakelwa kokusebenza okushisayo.
Ngokwehla kwayo, ukusebenza kahle kwezinto ezibonakalayo kuyanda, futhi kuba mncane.
- Idijithi ye-thermal countnivity of polystyrene kwakungu-0.028 W / MK;
- Polyfoam - 0.039 w / mk.
Uma kucatshangelwa lezi zinkomba, kungabonakala ukuthi i-polystyrere floam idlula izici zegwebu, hhayi kuphela, kodwa ngokuvamile, okunye ukufakwa okukhona.
Qinisekisa lokhu kungaba yilokho okulandelayo:
Isihloko ngesihloko: Indlu yangasese engenacala - kusuka ekukhetheni kuya kokufaka
| № | Into uqobo lwayo | Ukusebenza okushisayo |
|---|---|---|
| okukodwa | Styrofoam | 0.039 |
| 2. | Minvata. | 0.041 |
| 3. | Ukhonkolo oqinisiwe | 1,7 |
| okune | Isitini esibi esibi | 0.76 |
| isihlanu | Ubumbano lwezitini nge izimbobo | 0.5 |
| 6. | Ibha yokhuni egciniwe | 0.16. |
| 7. | Ceramzitobeton | 0.47 |
| isishiyagalombili | Gazilikat | 0.5 |
| isishiyagalolunye | Ukhonkolo foam | 0,3. |
| Okuthenyalwayo | I-Slagobeton | I-0,6 |
Ngenqaba yemishini
Ukunwetshwa kwe-polystyrere kancane kancane kune-foam plastic
Kuyadingeka ukuthi ungakhohlwa ukuthi i-polystyrere foam iyinhlangano enhle ye-monolith, futhi izinhlayiya zingamagwebu. Lokhu kuthinta kakhulu amandla ezinto zokwakha.
I-PolyStyrere Foam iyamelana nokuqhekeka kusuka ku-0.4 kuya ku-1 MPA, ukumelana kwayo ku-Compression kungu-0.25-0.5 MPA, futhi igwebu linezinga lemingcele, ngokulandelana, 0.05-0.2 MPA kanye no-0.05-0.2 MPA.
Kuyaziwa ukuthi igwebu, elivezwe emathonyeni amakhulu emishini, iqala ukuchoboza amabhola amancane futhi iphule. I-polystyrene ibuye yagcinwa umthwalo oqinile kanye nokwehluka kokushisa.
Ubuningi be-polystyrere ekwehlisiwe buyehluka kusuka ku-30 kuye ku-45 kg / m3, kanye negwebu - uketshezi luyehluka ohlwini lwama-15-35 kg.
Ngekhono lokuthola amanzi
IPolyfoam ithola kangcono amanzi, okuyisici esingesihle
Lesi ngesinye sezimpawu ezibalulekile zezinto zokufaka okushisayo, futhi le mpahla kufanele ibe mincane. Ngokuthola umswakama, ukufakwa kuzolahlekelwa izici zayo ezibaluleke kakhulu, kuzovuvukala futhi, kubo bonke, kuzoqala ukubola nokuwa.
E-polystyrene, enokwakheka kwamaselula, umswakama we-absorption zero. Ukucwilisa isikhathi eside futhi kungenamanzi ngokuphelele, kungaphawulwa ukuthi ukumuncwa kukaketshezi kungafinyelela ku-0,2% yevolumu yayo.
I-Polyfoam, ehlukaniswe ngukwakheka, lesi sici siphansi kakhulu. Ukucwilisa amahora angama-24 emanzini, kungaphawulwa ukuthi izinto ezithola i-2% yevolumu, ngezinsuku ezingama-30 kuzodonsa ama-4%.
Ngakho-ke yini okungcono: Foam noma i-polystyrere foam? Konke lokhu okungenhla kufakazela futhi izinzuzo zezinto ezibonakalayo zesibili ze-hydrophobic, ikakhulukazi uma kusetshenziselwa ukufaka izingxenye ezinjalo zesakhiwo njengesitezi somhlabathi, isisekelo kanye ne-facade.
Ngokuya kabusha
I-Flammity isebenza njengengxenye ebalulekile lapho izinto zidinga ukufakwa khona nokuba khona kwezakhiwo zokhuni - i-attic, ukuphapha. Kumele kwaziwe ukuthi zombili izinto zibalwa emaqenjini anekhono elivuthayo elivuthayo. Ngemininingwane engaphezulu mayelana nokwehluka kwezinto zokwakha, bheka le vidiyo:Isihloko ngesihloko: I-Woodrovnik ezweni lenze ngokwakho
Umkhiqizi waqala ukwengeza antipiren ekwakhekeni kwe-foam ne-polystyrene enwetshiwe - ngosizo lokuzivikela. Uma kunokuxhumana ngqo nomlilo, izinto zokwakha zizodonswa ngemizuzwana.
Ku-PredisoPhositions to shrinkage
Ngokungafani ne-Foam Plastic, i-polystyrene ayinakuguqukiswa eShrikage
Ukungathandeki okuyinhloko kwawo wonke ama-infartion kuyinto shrinkage. Ngento enjalo, kunezikhala ezinciphisa ukusebenza kwenqubo.
I-Polyfoam lapho kufudunyezwa kutholakala ku-shrinkage, ngakho-ke akunconywa ukuyisebenzisa kuhlelo "olufudumele lwaphansi".
Uma i-FOAM isetshenziselwa ukufakwa kwe-facade, kuyadingeka ukuyimboza ngodaka olumhlophe, oluvikela ngokumelene nemisebe ye-ultraviolet.
I-PolyStyrere Foam cishe ayiholwanga yi-shrinkage ngesikhathi sohlelo lokusebenza.
Ekushiseni lokushisa
Ibhalansi yokushisa evunyelwe ukusebenza nazo zombili izinto zokwakha - kusukela ku-50 kuye ku-75 degrees.
Uma weqa lezi zinkomba, impahla iqala ukuzidela.
I-Polyfoam ikhala ngama-310 degrees, anwebeka i-polystyrene - ngama-degrees angama-450.
Imvelo
Ukwakheka kwalezi zinto ezibonakalayo akukho zakhi eziyingozi, njengeFreyoni ne-Phenol. Ngemuva kwesikhathi, ukufakwa kungaqali ukwaba izinto eziyingozi, zisetshenziselwa ngokwesibindi ukuhlukanisa izakhiwo zomphakathi kanye nezakhiwo zokuhlala.Ngempilo yenkonzo
Ucwaningo luye lwabonisa ukuthi i-Pestlex, efakwe kahle, ingahlala iminyaka engama-50, ilondoloze ifomu.
Uma amakhono ezezimali womthengi awakufinyeleli ngaphambi kokuyithenga, igwebu lingasetshenziswa. Yebo, kuphansi kwe-polystyrere Foam ngokuchazwa, kepha kuzoba yinto engcono kakhulu evela ekufakweni okushibhile. Ngolwazi oluthe xaxa mayelana nezakhiwo ze-polystyrene foams, bheka le vidiyo:
Uma ubheka konke okunye, khona-ke impendulo yombuzo: I-Foam noma i-Polystyrere Foam, okungcono - inethempeli lempendulo: Yebo, i-polystyrerererenerererererererere esiteji kuzo zonke izinkomba.
