Sibolla Karolo ea Bohlokoa ea Li-Catalyst tsa Boleng bo Holimo Liphanele tsa Sandwich tsa PU tse Tšoarellang le tse Sebetsang Hantle
1. Selelekela sa Diphanele tsa Sandwich tsa Polyurethane
Liphanele tsa sandwich tsa polyurethane (PU) li sebelisoa haholo kahong, polokelong e batang, le ho kenya mocheso indastering ka lebaka la bokhoni ba tsona bo ikhethang ba mocheso, sebopeho se bobebe, le matla a mechini. Karolo ea bohlokoa ea tlhahiso ea tsona ke: li-catalyst tsa polyurethane, tse khethollang ts'ebetso ea foam, bongata le thepa ea ho qetela.
2. HobanengLi-catalystBohlokoa ho Tlhahiso ea Liphanele tsa Sandwich tsa PU
Khetho ea catalyst e ama ka kotloloho:
- Boleng ba Foam: Dikarabelo tse leka-lekaneng tsa gelling/blowing di netefatsa sebopeho se tshwanang sa sele.
- Lebelo la ho Folisa: Linako tsa ho fokotsa peo ka potlako li eketsa katleho ea tlhahiso.
- Ho Tsitsisa Thempereichara: Ke habohlokoa bakeng sa diphanele tse sebediswang maemong a feteletseng a mocheso.
- Ho Thibela Mollo: Di-catalyst di ka ntlafatsa di-formula tse sa cheng.
3. Litšebeliso tsa Bohlokoa tsa RonaLi-Catalyst tsa Polyurethane
Li-catalyst tsa rona tse khethehileng li entsoe bakeng sa:
a. Diphanele tsa Kaho le Meaho
- Metswako e nang le sekgahla se phahameng bakeng sa botsitso ba sebopeho.
- Metswako e tlase ya VOC e dumellanang le maemo a moaho o motala (mohlala, LEED).
b. Polokelo e batang le Lipalangoang tse Sehatsetsing
- Tshebetso e phahameng ea ho kenya mocheso (boleng bo tlase ba k).
- Ho hanyetsa mongobo bakeng sa ho tšoarella nako e telele.
c. Ho Sireletsa Litšila Liindastering
- Li-catalyst tse hananang le asiti bakeng sa libaka tse thata.
- Liprofaele tsa reactivity tse ikhethileng bakeng sa mela e tsoelang pele ea lamination.
4. Melemo ea Tekheniki ea Litharollo tsa Rona tsa Catalyst
- Mekhoa e Nepahetseng: E etselitsoe tlhahiso ea phanele e otlolohileng/e otlolohileng.
- Dikgetho tse Sireletsang Tikoloho: Mekgwa e meng e fumanehang e se nang amine le e fokotsang mosi o tswang.
5. Sebelisana le Mofani oa Catalyst ea Tšepahalang
Jwalo ka moetsi ya ka sehloohong wa di-catalyst tsa polyurethane, re thusa bahlahisi ba diphanele tsa sandwich:
✅ Fokotsa linako tsa potoloho ka 15-20% ka ts'ebetso e ntlafalitsoeng.
✅ Seha litšila tsa thepa ka taolo e nepahetseng ea foam.
✅ Finyella sehlopha sa boleng bo tsitsitseng kamora sehlopha.
Pitso ea ho Nka Khato (CTA)
Na o hloka catalyst e ntlafatsang tshebetso ya phanele ya hao ya sandwich?
