Makala a indasteri le a kaho a hlōlisanang kajeno, liphanele tsa sandwich li fetohile tsa bohlokoa bakeng sa ho theha meaho e bobebe, e matla le e sebetsang hantle mochesong. Motheong oa ts'ebetso ea tsona ho na le foam ea polyurethane (PU)—e leng thepa e khonehang ka lebaka la ts'ebetso e phahameng.li-catalyst tsa polyurethaneJwalo ka moetsi ya ka sehloohong wa di-catalyst tsa PU, re ikgethile ka ditharollo tse ikgethileng tse susumetsang bokgoni, botsitso le boqapi tlhahisong ya diphanele tsa sandwich.
Liphanele tsa Sandwich ke Eng?
Diphanele tsa sandwich ke meaho e kopaneng e entsweng ka dikarolo tse pedi tse ka ntle—hangata maqephe a tshepe—le thepa ya mantlha jwalo ka foam ya polyurethane. Karolo ya mantlha e fana ka ho kwahela le ho tiya, ha matlalo a kantle a fana ka matla a sebopeho le ho tshwarella. Diphanele tsena di sebediswa haholo ho:
Likamore tsa polokelo e batang
Meaho e modular
Likamore tse hloekileng
Marulelo le li-cladding tsa indasteri

Hobaneng Foam ea Polyurethane e Loketse Bakeng sa Liphanele tsa Sandwich
Foam ea polyurethane e ratoa ka lebaka la ho thibela mocheso hantle, boima bo tlase, le ho khomarela ka matla thepa e ka holimo. Sebopeho sa eona sa lisele tse koetsoeng se thusa ho hanela mongobo le ho ntlafatsa ts'ebeliso e ntle ea matla—e leng ea bohlokoa lits'ebetsong tse kang lipalangoang tse sehatsetsing le lits'ebeletso tse laoloang tikolohong.
Empa ho hlahisa foam ea PU ka sebopeho se nepahetseng sa sele, nako ea ho fola le matla ho hloka taolo e nepahetseng. Ke moo li-catalyst tsa polyurethane li kenang teng.
Karolo eaLi-Catalyst tsa PolyurethaneTlhahisong ea Liphanele tsa Sandwich
Li-catalyst tsa polyurethane ke metsoako ea lik'hemik'hale e laolang karabelo lipakeng tsa li-isocyanate le li-polyol—karabelo ea mantlha ho thehoeng ha foam ea PU. Lits'ebetsong tsa pane ea sandwich, li-catalyst tsena li netefatsa:
1. Linako tsa Karabelo tse Potlakileng le tse Laoloang: Li-catalyst li ntlafatsa lebelo la ho fola, li ntlafatsa katleho ea tlhahiso ha li ntse li boloka botsitso ba litekanyo.
2. Ho Sebetsana ka Tsela e Lekaneng: Tekanyo e nepahetseng pakeng tsa ho foka (ho etsa khase) le ho kopanya gelling (ho kopanya) e hlahisa li-cores tse matla, tse tšoanang tsa foam.
3. Sebopeho se Setle sa Sele: Li-catalyst tsa rona li khothalletsa boholo bo tsitsitseng ba lisele, li ntlafatsa ho thibela mocheso le matla a ho hatella.
4. Tshebetso ya ho kgomarela: Kgomarelo e ntlafetseng pakeng tsa foam le difahleho e netefatsa ho tshwarella nakong ya ho tsamaiswa, ho kenngwa le ho sebeletswa.
5. Ho Latela Tikoloho: Re fana ka dikgetho tsa catalyst tse nang le VOC e tlase le tse se nang thini tse lumellanang le maemo a tikoloho a lefatshe ka bophara.
Litšebeliso tsa Bohlokoa tsa Li-Catalyst tsa PU ho Liphanele tsa Sandwich
1. Ketane e batang le sehatsetsing:
Liphanele tsa sandwich tse nang le li-core tsa foam tsa PU li netefatsa hore ho na le mocheso o motle.
Li-catalyst tsa rona li thusa ho fihlella boleng bo phahameng ba ho thibela mocheso (boleng bo tlase ba λ) bakeng sa ho boloka matla.
2. Kaho ea Liindasteri le Khoebo:
Li-catalyst tse folisang ka potlako li tšehetsa mela ea tlhahiso ea liphanele tse lebelo le phahameng.
Thepa e ntlafetseng ea mechini e netefatsa bophelo bo bolelele ba ts'ebeletso le botšepehi ba sebopeho.
3. Meaho e Meholo le e Entsoeng Pele:
Li-catalyst li nolofalletsa liphanele tse bobebe empa li le matla, tse loketseng matlo a nkehang habonolo le kaho ea sebaka se hole.
4. Likamore tse Hloekileng le Libaka tsa Bongaka:
Foam e tšoanang e netefatsa tikoloho e sa keneleng moea le e se nang litšila.
Hobaneng re lokela ho khetha li-catalyst tsa rona tsa polyurethane?
Mekhoa e Ikhethileng: Re etsa liphutheloana tsa catalyst ho latela sistimi ea hau ea PU le mohala oa tlhahiso.
Tšehetso ea Tekheniki: Litsebi tsa rona li fana ka likeletso tse tebileng ho ntlafatsa boleng le tlhahiso ea phanele ea hau.
Ketane ea Phepelo ea Lefatše: Tsamaiso e tšepahalang ea thepa le ho latela melao ho pholletsa le libaka.
Tsepamiso ea Tšireletso: Litharollo tsa thepa ea ho thibela mocheso e se nang halogen le e nang le setifikeiti se setala.
Qetello
Hore na o hlahisa diphanele tsa sandwich bakeng sa indasteri ya kaho, ditsamaiso tsa sehatsetsi, kapa meaho ya modular, boleng ba foam ya hao ya polyurethane—le catalyst e ka morao ho yona—e ka etsa phapang e kgolo. Sebetsa mmoho le rona ho ntlafatsa tlhahiso ya hao ka ditharollo tsa catalyst tsa polyurethane tse sebetsang hantle, tse ka fetolwang tse etseditsweng ditshebediso tsa sejwalejwale tsa diphanele tsa sandwich.
Ikopanye le Rona Kajeno
Ikopanye le sehlopha sa rona sa botekgeniki ho buisana ka litlhoko tsa phanele ea sandwich ea hau le ho fumana hore na li-catalyst tsa rona tsa polyurethane li ka phahamisa sehlahisoa sa hau joang.
