Liphanele tsa sandwich tsa polyurethane, tse tsejoang haholo e le liphanele tsa PU, ke likarolo tse sebelisoang haholo kahong ea sejoale-joale le indastering ka lebaka la matla a tsona, ho tšoarella le thepa ea ho thibela mocheso. Liphanele li entsoe ka mekhahlelo e meraro e meholo: motheo oa foam ea polyurethane o sireletsang mocheso haholo 'me o kopantsoe pakeng tsa maqephe a mabeli a tšepe a tiileng. Sebopeho sena se kopaneng se na le botsitso bo botle ba sebopeho, ho sireletsa mocheso le ho hanyetsa boemo ba leholimo, e leng se etsang hore e be se loketseng libaka tse fapaneng. Li-catalyst tsa polyurethane tlhahisong ea liphanele tsena li netefatsa tlhahiso e sebetsang hantle le ts'ebetso ea li-core tsa foam.
Sehlopha sa Sandwich ke eng?
Phanele ea sandwich ke mofuta oa thepa ea kaho e kopanyang khubu ea foam ea polyurethane le likarolo tse ka ntle, hangata tšepe, ho etsa thepa e kopaneng e sebetsang hantle. Khubu ea foam, e entsoeng ka karabelo ea lik'hemik'hale e susumetsoang ke li-catalyst tsa polyurethane, e fana ka ho thibela mocheso o motle, e thusang ho boloka mocheso o tsitsitseng oa kahare mehahong le lisebelisoa. Likarolo tsa tšepe tse ka ntle li eketsa ho tiea ha sebopeho, tšireletso le ho tšoarella. Motsoako ona o fana ka tharollo e bobebe empa e tšoarella bakeng sa mabota, marulelo, polokelo e batang, le lits'ebetso tse ling moo ts'ebeliso ea matla, boima le matla li leng bohlokoa.
Karolo ea Li-Catalyst tsa Polyurethane ho Liphanele tsa Sandwich
Li-catalyst tsa polyurethane li bohlokoa haholo ho hlahiseng foam core ea liphanele tsa sandwich. Li-catalyst tse kang MXC-T le MXC-C15, e 'ngoe le e 'ngoe e na le thepa e ikhethang, li potlakisa liketso lipakeng tsa li-polyol le li-isocyanate, e leng se lebisang ho thehoeng ha foam ka bongata le sebopeho se lakatsehang.
1.MXC-Te sebediswa haholoholo tlhahisong ya foam e bonolo e thehilweng hodima polyether, foam e bopilweng, foam e thata hanyane, le foam e thata. Diphanele tsa sandwich, MXC-T e thusa ho laola sebopeho sa foam, e fana ka sekgahla se leka-lekaneng sa karabelo le sebopeho se tsitsitseng sa sele. Ho tsitsa hona ho netefatsa ho kwahela mocheso ho tshwanang mme ho ntlafatsa botshepehi ba sebopeho sa phanele.
2.MXC-C15, e leng amine catalyst, e loketse haholo bakeng sa ho bopa ka bonolo le hanyane-bonolo hammoho le ts'ebeliso ea foam e thata. Liphanele tsa sandwich, e thusa ho fihlella sebopeho se tsitsitseng sa foam se bolokang thepa ea sona ea ho thibela mocheso tlas'a mocheso o fapaneng. Taolo ea MXC-C15 holim'a karabelo e thusa ho fihlela bongata bo loketseng ba foam le botsitso ba litekanyo, e leng se etsang hore liphanele li haneloe haholoanyane ke ho fetoha le khatello ea tikoloho.
Litšebeliso tsa Liphanele tsa Sandwich tsa PU
Liphanele tsa sandwich tsa polyurethane li sebelisoa haholo libakeng tsa polokelo ea lintho tse batang, mehahong ea indasteri, mehahong ea khoebo le lipalangoang tse sehatsetsing, moo ho boloka taolo ea mocheso ho leng bohlokoa. Liphanele tsa sandwich tsa polyurethane li bobebe, li potlakile ho kenngoa, li na le moroalo o fokolang oa sebopeho, 'me li hanela maemo a leholimo a feteletseng bakeng sa bophelo bo bolelele ba ts'ebeletso. Tšebeliso ea li-catalyst tsa polyurethane tse inehetseng ts'ebetsong ea tlhahiso e ntlafatsa thepa ena, e leng se etsang hore liphanele tsa sandwich tsa polyurethane e be khetho e pharaletseng bakeng sa litharollo tsa moaho tse bolokang matla le tse tšoarellang.
Ka bokhutšoanyane, motsoako oa foam ea polyurethane le li-catalyst tse sebetsang hantle tse kang MXC-T le MXC-C15 li hlahisa liphanele tsa sandwich tse nang le ho thibela mocheso o motle, matla le ho hanyetsa boemo ba leholimo, tse tšehetsang mekhoa ea kaho e tsitsitseng le e sebetsang hantle.
