Styrofoam, penopolx: iimpawu, ukuthelekisa nokuhlaziywa

Abaninzi bakholelwa ukuba i-styrofoam, i-penopollex yinto efanayo. Abanye abaphathi bezindlu bathi abo magama bafana. Kodwa ukuba ukhangele ngakumbi, kulezi zimbini iziganeko sithetha ngazo iintlobo ezahlukahlukeneyo zokuxhoma.

Impawu

Ukuze uqonde ukuba yeyiphi enye imveliso ekhankanywe apha ngasentla, kubalulekile ukuziqonda ngeempawu. I-Penoplex yenziwe nge-polystyrene, ukunyunyibilika kwenzeka ngexesha lomveliso, ngenxa yoko, isakhiwo esidibeneyo sakha. Ekugqibeleni, izinto zifumana iimpawu zokuqina, amandla aphezulu, ukungathobeli ukubola, i-plasticity, i-coefficient ephantsi kunye nokuqhuba umthambo, ukukhusela ukuguquka kweqondo lokushisa. Phakathi kwezinye izinto, i-penoplex inesisindo esinyanisekileyo. Kodwa kukho ezinye izithintelo, eziziindleko eziphezulu, ukukhutshwa kweminye imisebe ye-ultraviolet, ukuncibilika phantsi kwefuthe lokushisa okuphezulu, kunye nokubonakaliswa kwamagundane.

Izixhobo eziphathekayo

I-Styrofoam, i-penopolx yilezi zinto ekubonweni kokuqala zibonakala zifana. Nangona kunjalo, owokuqala uneminye impawu, nangona iyenziwe nge-polystyrene pellets. Ziye zacutshungulwa ngexesha lokuveliswa kwe-steam ezomileyo, ekugqibeleni zihlanganiswe ndawonye, zenze i-pores microscopic. I-polystyrene eyandisiweyo ibonakaliswe njengenkunkuma ngenxa yempawu zayo zobunjani, phakathi kwazo ziyakwazi ukwahlukana: ukukhuselwa kwamakhemikhali, utshintsho lokushisa, ukulungiswa kofakelo, ubunzima obuphantsi kunye neendleko ezibiza. Nangona kunjalo, unemingcipheko ethile, umzekelo, ukugoba impahla ingakwazi ukudiliza, ukukhulula izinto ezinobuthi ngexesha lobushushu, kwaye utshabalalise xa ubonakala kwintlambo. Ngaphantsi kwempembelelo yezinto ezenziwe ngopende kunye nezinto zokugcoba i-varnish ziyachithwa, kwaye zibonakaliswe nakwiigundane.

The lekiswa

Nangona i-styrofoam, i-penopolx zizinto ezihlukeneyo, zininzi ezifanayo. Usuke uqaphele, zilula, zibonakalisa iimpawu eziphezulu zokushushumbisa i-thermal kwaye kulula ukuyifaka. Nangona kunjalo, kukho ukungafani, oku kukuxhalabisa ubukhulu bamandla, ukhuseleko lomlilo, ukuphepha kwamanzi kunye nobomi benkonzo. Kodwa olu luhlu alukwazi kuthiwa luphelele. Ukuba uhamba ngokubanzi malunga neempawu, amandla ezi zinto ziphezulu, kodwa i-foam inamandla kakhulu, kuba ibonisa ubunzima bonke.

Ngokuphathelele ukhuseleko lomlilo, zombini izinto ezisetyenziswayo zivuthayo, zikhulula izinto ezinobungozi emoyeni. Nangona kunjalo, i-foam iyakwazi ukubola ngokuzimela. Ukuba ufuna ukuxhobisa i-facade ye-ventilation, ngoko kukulungele ukusebenzisa i-polystyrne eyandisiweyo, ekubeni ikwazi ukuphefumula, ngokungafani ne-penopolix. Ubomi benkonzo buyakucingelwa kakhulu, kodwa abaninzi abathengi bakholelwa ukuba i-polystyrene eyandisiweyo iyakwazi ukugqithisa ngokukhawuleza, ilahlekelwa yimpawu zayo zomoya. Emva kokufakela, uya kuqaphela ukuba ipenkix ayikwazi ukunqumla umphunga, kuba akukho zimbalo kwisakhiwo sayo.

Ukubhekisela

Umthengi wanamhlanje unika ingqalelo kuyo yonke into, kuquka neendleko. Ukuba ufuna ukugcina, kulungile ukuthenga i-polystyrne eyandisiweyo, kodwa iindleko ezipheleleyo ziya kuxhomekeka kumenzi.

Impendulo kwiindawo zokusetyenziswa

I-Styrofoam, i-penopollex zixhobo ezingasetyenziselwa uluhlu lwemisebenzi eyahlukileyo. Nangona kunjalo, abasebenzisi bacebisa ngaphambi kokukhetha i-heater ukuba baqwalasele iimpawu zezi zinto. Ngokomzekelo, ukuba i-facade icetyiswa ukuba isebenzise i-polystyrene enwetshiwe, eneempawu zomoya ukuphelela. Ngethuba lologi kunye namabhaloni, i-penoplex ifanelekile, engaphantsi kobunzima, ngenxa yokuba kunokwenzeka ukuba ugcine indawo ekhululekile.

Ngaphakathi kwindlu, kucetyiswa ukuba ucinge ngenye indlela, ukuze ungaphazamisi ukufuduka kwendawo yamanzi kunye nokukhutshwa kwezinto ezinobungozi emoyeni. Ngokwabasebenzisi, akukho ntlukwano ebalulekileyo phakathi kweentlobo ezimbini zokutshitshiswa kwe-thermal xa ulungisa isilingi, umgangatho kunye nophahla. Ngaloo ndlela, i-foam ibonakaliswe ngamandla angaphezulu, okuvumela ukuba ushiye ukufakwa kwesiteji kwinkqubo ye-attic space. Phakathi kwezinye izinto, ingasetyenziselwa ukutshitshiswa kwamafutha emibhobho, ngenxa yokuba inamandla aphakamileyo, enokubaluleka kwedwala, kunye nesiseko.

Unzima ukhetho

Ukuba uqhuba uphando, abathengi baya kuthi i-polystyrene eyandisiweyo yinto engaphantsi kwezinto ezikhoyo, kuya kuthatha okungakumbi ukuyibeka, iya kuthatha umswakama ngexesha lokusebenza. Nangona kunjalo, ukusetyenziswa kweentlobo ezithile ze-penoplex kwezinye iimeko akunjalo.

Iinkcukacha zePenopolix 35

Kungekudala, i-polystyrene eyandisiweyo ilahlekelwa yintando yayo. I-Penoplex 35, eneempawu eziza kuboniswa ngezantsi, zisetyenziswa kakhulu. Xa kuthengiswa namhlanje ungayifumana ukutshitshiswa kwe-thermal yalolu hlobo ngokusekwa kunye nophahla. Kwimeko yokuqala, iiplate ziyakwazi ukumelana nemithwalo enzima, evumela ukusetyenziswa kwe-thermally insulation for paths, floors and socles, apho ukumelana nokutsha komlilo akubalulekanga.

Ubuninzi bolu xwebhu buyahlukahluka ukusuka kwi-29 ukuya kwi-33 kg / m³, ngelixa amandla okhathazekayo angama-0.27 MPa. Kwiintsuku ezingama-28 ezi zinto ziyakuthabatha amanzi angama-0.5% ngexabiso. Ukuba uqala nje ukwakha indlu yakho, kungcono ukuba ungathengi i-polystyrene eyandisiweyo. I-Penoplex 35, ene-conductivity ye-thermal yi-0.33 W / (m × ° K), igqibelele isiseko. Izinto eziphathekayo zingasetyenziselwa ubuninzi beqondo lokushisa, ezihluka ukusuka -50 ukuya kwi -75 ° C.

Ububanzi bezinto eziphathekayo bunokuba ngu-600 mm, ngelixa ubude buyi-1200. Unokulinganisa ubukhulu obufanayo kunye nokwandisa i-polystyrene. I-penoplex 50 mm iyona nto ixhaphakileyo, kodwa kuthengiswa ungayifumana enye ubukhulu, obuya kwi-20 ukuya kwi-100 mm. Ukuba kuyimfuneko, i-foam ingasetyenziselwa ukufaka uphahla. Idizayini inokuthi ibe nayiphi na uhlobo, kodwa ngokuqhelekileyo le nto isetyenzisiweyo isetyenziselwa ukuphahla okulula.

Iindawo zokusebenzisa "uphahla lwePenoplex" ziphahla eziphefumlelweyo, kunye namagumbi okugubha. Njengoko umkhuba ubonisa, kwiminyaka yamuva nje, ukusetyenziswa kwe-polystyrne foam ekhutshwe ngokungaqhelekanga, ipenoplex 35 (i-penoplex - yile ndlela eyaziwa ngayo kumthengi wanamhlanje) isetyenziselwa ukukhutshwa kwephahla lohlobo lwe-inversion, oluvumela ngempumelelo ukusetyenziswa kwesakhiwo ngeenjongo ezahlukeneyo. Kuyo unokwenza isiqithi esiluhlaza, uvelise iintyatyambo kunye nemithi. Kufanelekile ukukhumbula ukuba i-foam iyakwazi ukunyathela imithwalo ephakamileyo, ngoko kuyaqheleke kakhulu ekugxineni kweziseko kunye negazi.

Impawu zePenopolix 45

Ukuba awukwazi ukuba yiyiphi into ekufuneka uyithathe, unako ukubeka ingqalelo kuloo ozayo ngokumakisha "45". Isetyenziselwa ukugxilwa kwetransti yeendlela zomzila, izithuthi zeendlela kunye neendlela zokuhamba nge-aerodrome. Ukuba umphezulu uphantsi kwemithwalo ephezulu, ngoko akufanelekile ukuthenga i-polystyrene foam, ipenokleks 45 ifanelekile ukuxhoma, xa kufuneka ibe namandla kangangoko. I-coefficient conductivity ye-thermal conductivity yale ngcaciso ngu-0.03 W / (m × ° K), kanti ubuninzi bungahluka ukusuka kwi-35 ukuya kwi-47 kg / m³.
