Ho kenyelletsa foam. Ho hlahisa liphaephe ka ho kenya li-polyurethane

Hona joale ho ruruha ha polari ea polyurethane ho nkoa e le eona e atlehileng ka ho fetisisa, kaha thepa ena e na le coefficient e tlaase ka ho fetisisa ea conductivity, hape e na le thepa e ntle ea ho thibela metsi. Tšobotsi ea ho qetela e bakoa ke ho ba teng ha karolo ea 99 lekholong ea pores e koetsoeng ha ho etsoa boitsebiso boo. FPU ho kenya letsoho ha e nke lehlakore liphellong tsa lik'hemik'hale, li-media tsa alkaline le metsoako ea acidic. Ke ea sehlopha sa ho chesa G2 'me se na le tšusumetso e phahameng ho tšusumetso e ka ntle.

Tlhaloso e akaretsang

Phofu e nang le li-polyurethane tse nang le li-polyurethane tse nang le limela tse ngata li na le matlotlo a matle a ho boloka mocheso. Ka lebaka la thepa ena, e loketse ho rarolla mathata a litsebi tsa ho qhoqha mocheso, e leng mabaka a moruo le a theknoloji a bonts'ang ho boloka matla a ho boloka matla. Ho kenngoa ha metsi ha boitsebiso ha bo felle ka 1.2-2.1% ea palo eohle. Ho kenya letsoho ho thata ho chesa esita le ho pepeseha ka ho toba mollong.

Ho qhoqhoa ha PPU ho na le boima ba 'mele bo fokolang, bo fapaneng ho fihlela ho lik'hilograma tse 60 ka k'hilograma. E khetholloa ke matla a maholo le ho sireletsoa ha lichelete mehaho ea tšepe. Ha u kenya, ha ho hlokahale hore u sebelise li-fasteners tse eketsehileng, ha ho ntse ho etsoa, marokho a batang ha a thehoa . Ho arohana le boitsebiso bona ho ka etsa leha e le efe tlhahlobo le boholo.

Ho tsitsa

Ho qhibiliha ha polari ea polyurethane ho khetholloa ke ts'ebetso ea eona ea nako e telele, e bakoang ke taba ea hore boitsebiso ha bo boliloe 'me ha bo lumelloe tlasa tšusumetso ea linako tse sa tšoaneng tsa mocheso le mocheso. Ha ho pelaelo hore re na le botsoalle bo phahameng ba tikoloho, kahoo, litekanyetso tsa bohloeki, thepa e ka sebelisoa theknoloji e batang, e reretsoeng ho boloka lihlahisoa tsa lijo.

Ho qhoqhoa ho entsoe ke theknoloji ea ho tšollela folase ea polyurethane ka hlobo, eo ho eona ho ka khonehang hore ho thehoe likhetla tse bitsoang likhetla. Li sebelisetsoa tokisetso ea liphaephe, ho hlahisa li-sandwich panels le slabs. Polyurethane foam e ka tšeloa holim'a lisebelisoa leha e le life tse kang tšepe, lehong, litene, khalase le konkreite. Tabeng ena, tlhophiso ea holim'a metsi ha e na taba.

Ho etsa liphaephe tse nang le polyurethane insulation

Thibelo ea PPU, ho etsoa ha eona ho tla hlalosoa ka tlase, e sebelisoa ho etsa liphaephe tse hlokang tšireletso e khethehileng. Phello ke sehlahisoa sa thermally insulated, se etsoang ho latela GOST 30732-2006. E le thepa ea ho kenya letsoho mofuteng tabeng ena, ho sebelisoa polase ea polyurethane, athe ho sireletsa mongobo ho netefatsoa ke boteng ba polyethylene. Liphaephe tse joalo li reretsoe ho hlophisa mahlakoreng a futhumatsang, ho kenngoa ha sepakapaka. Ha ho etsoa lisebelisoa tsena tse tharo, lisebelisoa tse boleng bo phahameng li sebelisoa, tseo ho tsamaisoang ho pholileng ho tla etsoa ka tsona.

Lisebelisoa li sireletsoa ke polase ea polyurethane, eo ka ho feletseng e felisang ho lahleheloa ke mocheso. Lisebelisoa tsa tšepe le polyurethane li sireletsoa metsing a mongobo, e leng ho netefalitsoeng ka ho ba le sekoahelo se khethehileng, se entsoeng ka polyethylene. Liphalaipi tsa tšepe ka ho kenya likhahla tsa PPU li ka ba mefuta e 'meli, e' ngoe le e 'ngoe ea eona e nka tšebeliso ea boima ba eona.
