Tlhahiso ea foam ea memori ke mohlolo oa 'nete oa k'hemistri le indasteri ea sejoale-joale.Foam ea memori e etsoa ka ho sebetsana le lintho tse fapaneng ka mokhoa o ts'oanang le polyurethane, empa ka li-agent tse ling tse etsang viscous, thepa e teteaneng e amanang le foam ea memori.Mona ke ts'ebetso ea mantlha e amehang tlhahisong ea eona:
1.Polyols (lino tse tahang tse tsoang lihlahisoa tsa petroleum kapa oli ea limela), li-isocyanate (li-organic amine-derived compounds) le li-reacting agents li kopantsoe hammoho pele ho tlhahiso.
2.Motsoako ona o ntan'o shapuoa ka froth ebe o tšela ka hlobo.Karabelo ea exothermic, kapa e lokollang mocheso, ke phello, e etsang hore motsoako o phatlohe ebe o hlahisa lekoeba.
3.Motsoako o nang le lekoeba o ka tšeloa ka khase kapa lisebelisoa tse butsoelang, kapa o tiisitsoe ka vacuum ho theha matrix a lisele tse bulehileng.Palo ea motsoako oa polymer khahlano le moea o tsamaisana le bongata bo hlahisoang.
4.Nakong ena, karolo e kholo ea foam e bitsoa "bun".Ebe bun e ea pholile, ebe e futhumatsoa hape ka mor'a moo e tloheloa hore e phekole, e ka nka lihora tse 8 ho isa matsatsing a 'maloa.
5.Ka mor'a ho phekola foam ea memori ke inert (ha e sa sebetsa).Thepa e ka 'na ea hlatsuoa le ho omisoa ho tlosa mesaletsa,' me joale e ka hlahlojoa boleng ba eona.
6. Hang ha bun ea foam ea memori e felile, joale e khaola likotoana bakeng sa ho sebelisoa materaseng le lihlahisoa tse ling.Likotoana tsa boholo ba materase joale li se li loketse ho kopanngoa betheng e felileng.
Phatlalatso: Tse ling tsa litaba/litšoantšo tse sengolong sena li tsoa Marang-rang, 'me mohloli o hlokometsoe.Li sebelisoa feela ho bontša lintlha kapa maikutlo a boletsoeng sehloohong sena.Li etselitsoe feela puisano le ho ithuta, 'me ha li molemong oa khoebo.Haeba ho na le tlolo ea molao, ka kopo ikopanye le rona ho hlakola hanghang.
