Uninzi lwabathengi bacinga ngale ngxaki: I-foam okanye i-polystyrene foam, yintoni ebhetele ukufaka isicelo sokufakelwa kunye nokufakwa kwesandi? Abanye bade bakholelwe ukuba zizixhobo ezifanayo nezifana.
Le nyaniso iqinisekisa ulwazi kwi-Intanethi. Eyona nto inokwenzeka, oku kuyenzeka ngenxa yokuba zenziwe nge-polystyrene, kodwa ngendlela enononophelo ungabona ukuba umahluko usekhona.
Umahluko kwi-foam kunye ne-polystrene
Xa iqhubela phambili i-Polystyrene Pellets, i-steam eyomileyo ijika igwebu
Umahluko omkhulu phakathi kwezi zinto zilandelayo:
- Kwitekhnoloji yemveliso yezi sampuli kukho umahluko omkhulu. I-Polyfoam yenziwa kusetyenziswa i-polystyrene pellets ene-steam eyomileyo. Ukwanda phantsi kwempembelelo yobushushu, bayabopha ngokuqinileyo omnye komnye, ngale ndlela imicrosores yenziwa. I-polystrene foam okanye ipenilex – Eli ligama lakhe lokurhweba, eliveliswa yindlela "yokuphuma". I-Polystyrene Granules inyibilikisiwe kuzo zombini iimeko, iibhondi zemolekyuli zisenziwa, isakhiwo esinye senzekile.
- Kukho umahluko phakathi kweempawu zomzimba nezobuchwephesha ngenxa yetekhnoloji yemveliso yazo. Ukuba sithetha ngokungagungqiyo, esandisiweyo i-polystyrene kwimiqondiso eyahlukeneyo ingaphezulu kwegwebu.
Umahluko weepropathi ezisebenzayo yiMpazamo
Ukuqhubela phambili kwengqondo esebenzayo ngakumbi, i-bimbile inokuba lonto
Yintoni ebhetele ukufaka isicelo sokufakelwa - i-polystrene foam okanye igwebu?
Ukuhlalutya amandla ezinto eziphantsi kokuqwalaselwa, ukungaboni ngasonye kunokuqatshelwa.
Owona mlinganiswa uphambili wokufakwa kwe-subrmas yokuqhutywa.
Ngokuncipha kwawo, ukusebenza ngokukuko kwezinto zonyuso kwezinto, kwaye iqhina.
- Idijithali yokuphumelela kwe-polystrene yayingu-0.028 W / MK;
- I-Polyfoam - 0.039 w / mk.
Ukuqwalaselwa kwezi zikhombisi, kunokubonwa ukuba impundu ye-polystrene ingaphezulu kweempawu zengqokelela, kwaye ayingeyiyo kuphela, kodwa ngokubanzi, enye i-inshusithisi.
Qinisekisa oku kunokuba zezi zibakala zilandelayo:
Inqaku ngesihloko: Indlu yangasese engenalo ngaphandle-ukusuka ekukhetheni ukuze ufakelo

Ngenqaba yoomatshini
I-Polystrene eyandisiweyo ingaphantsi kweplastikhi ye-foam
Kuyimfuneko ukuba ungalibali ukuba i-Polystyrene Fom yi-monolith elungileyo, kwaye amasuntswana ayabile. Oku kuchaphazela kakhulu amandla esixhobo.
I-Polystrene Fom ixhaphakile ukuba ihlukane ne-0.4 ukuya kwi-1 MPA, ukuxhathisa i-MPA ngu-0,25-0.5 MPA kunye ne-0.05-0.2 MPA.
Kuyaziwa ukuba i-foam, ityhilwe kwiimpembelelo ezinzulu zendlela, iqala ukutyhoboza iibhola ezincinci kunye nekhefu. I-polystyrene ikwagcinwa nomthwalo oqinileyo kwaye inobushushu umahluko.
Ukuxinana kwe-Polystyrene ye-polystyrene yahluka ukusuka kwi-30 ukuya kwi-45 kg / m3, kunye ne-foam-fluid yahluka kuluhlu lwe-15-35 kg.
Ngokukwazi ukufunxa amanzi
I-Polyfoam ibhetele ifumana amanzi, eliyinto engeyiyo
Le yenye yeempawu ezibalulekileyo zezinto zokufakwa kwe-insholm, kwaye le propati kufuneka incinci. Ngokufumana umswakama, i-fanser iya kuphulukana neempawu eziphambili, ziya kudumba kwaye, kubo bonke, ziya kuqala ukujikeleza kwaye ziwa.
Kwi-polystyrene, enokwenziwa iselfowuni, ukufunxa kwe-zero. Ukuntywilisela ixesha elide kwaye kubini amanzi, kunokuqatshelwa ukuba ukufunxa ulwelo kunokuba yi-0.2% yevolumu yayo.
I-Polyfoam, yahlulwe kukuqulunqwa, eli nqaku liphantsi kakhulu. Ukuntywilisela iiyure ezingama-24 ukuya emanzini, kunokuqatshelwa ukuba izinto ezibonakalayo zithathe i-2% yevolumu, kwiintsuku ezingama-30 ziya kutshabalalisa iipesenti ezi-4.
Ke yintoni engcono: igwebu okanye i-polystrene foam? Zonke ezi zinto zilapha ngasentla ziphinde zingqina izibonelelo zezinto ezimbini ze-hydrophobic ze-hydrophobic, ngakumbi ukuba isetyenziselwa ukudibanisa iinxalenye zesakhiwo njengomgangatho womhlaba, isiseko kunye ne-foude.
Ukwalathisa
Ukuvuselelwa kwezenzo njengecandelo elibalulekileyo xa izinto kufuneka zifakwe i-arhente yobukho bamaplanga - i-attic, aphaphandle. Kufuneka iqatshelwe ukuba zombini izixhobo zibalwa ngokwamaqela amandla anyukayo anyukayo. Ngolwazi oluthe kratya malunga nomahluko kwizixhobo, jonga le vidiyo:Inqaku lesihloko: I-Woodrovnik kwilizwe lenza ngokwakho
Umenzi waqala ukongeza i-Antipheren ukuya kwi-foam ye-foam kwaye yandiswa i-polystyrene-kunye ne-insulture yayo yokuzithemba. Ukuba akukho nxibelelwano ngqo nomlilo, ziya kutsalwa imizuzwana.
Kwindawo eqingqiweyo kwi-shrinkage
Ngokungafaniyo neplastiki ye-foam, i-polystrene ayinakuphepheka kwi-shrinkage
Eyona nto igwenxa kuyo yonke into yokufakelwa i-speinkige. Ngento enjalo, kukho izithuba ezinciphisa ukusebenza ngempumelelo kwenkqubo.
I-Polyfoam xa ishushu ibekwe kwindawo yokuhluza, ngenxa yoko ayicetyiswanga ukuyisebenzisa kwinkqubo ethi "suble".
Ukuba inyibiliki isetyenziselwa ukufunyanwa kwebala, kuyimfuneko ukuyigubungela ngodaka olumhlophe, olukhuseleka kwimitha ye-ultraviolet.
Umgwebi wepolystyrene phantse akakhokelwa nguShiys ngexesha lesicelo.
Kwiqondo lokushisa
Ibhalansi yeqondo lobushushu ivunyelwe ukusebenza kunye nezixhobo zombini - ukusuka kwi-50 ukuya kwi-75 degrees.
Ukuba ugqibile ezi zikhombisi, umbandela uqalisa ukufezekisa.
I-Polyfoam izibane ngama-310 degrees, eyandisiweyo i-polystyrene-nge-450 degrees.
I-ecology
Ukuqulunqwa kwezi ndawo azinazinto ziyingozi, ezinjenge freon kunye ne-phenol. Emva kwethuba, ukufakelwa akuqali ukwabela izinto eziyingozi, zinokusetyenziselwa ngokuzithemba ukwahlula izakhiwo zikarhulumente kunye nezakhiwo zokuhlala.Ngobomi benkonzo
Izifundo zibonakalisile ukuba i-piestelex, efakwe ngokuchanekileyo, inokuhlala iminyaka engama-50, ilondoloze ifom.
Ukuba ubuchule bezezimali bomthengi abayifikeleli ngaphambi kokuthenga, i-foam ingasetyenziswa. Ewe kunjalo, iphantsi kwe-polystyrene foam ngokubhekisele kwinkcazo, kodwa iya kuba yeyona nto ibalaseleyo yokufakelwa kwexabiso eliphantsi. Ngolwazi oluthe kratya malunga neepropathi ze-polystyrene foam, funda le vidiyo:
Ukuba ucinga yonke enye into, emva koko impendulo yombuzo: I-foam okanye i-polystyrene foam, enesigwebo esigqibeleleyo - igwetywe i-pilystyrene ye-polystyrene kwi-foam yenqanaba ngaphezulu kwegwebu elingaphezulu kwegwebu kuzo zonke izikhombisi.
