Liphanele tsa sandwich li fetohile karolo ea bohlokoa kahong ea sejoale-joale ka lebaka la ho thibela mocheso ho ikhethang, matla a sebopeho le bokhoni ba ho kenya. Har'a mefuta e fapaneng ea liphanele tsa sandwich, tse nang le thepa ea mantlha ea polyurethane (PIR) li ntse li khethoa haholo liindastering ka lebaka la ts'ebetso ea tsona e phahameng. Joaloka moetsi oa li-catalyst tsa polyurethane tse sebetsang hantle, re motlotlo ho tšehetsa tlhahiso ea liphanele tsena ka litharollo tse tšepahalang le tse sebetsang hantle joalo kaMXC-T, MXC-C15,leMXC-37.
Liphanele tsa Sandwich ke Eng?
Liphanele tsa sandwich ke thepa ea moaho e kopaneng e entsoeng ka mekhahlelo e meraro: thepa ea mantlha e nang le botebo bo tlase, joalo kapolystyrene e atolositsoeng (EPS), ulu ea diminerale,orpolyurethane (PIR), le mealo e 'meli ea letlalo la ka ntle, hangata e entsoe ka maqephe a tšepe. Kaho ena e nang le mealo e fana ka litekanyo tse phahameng tsa matla ho ea boima, e leng se etsang hore liphanele li be tse loketseng merero e fapaneng ea sebopeho le ea ho thibela ho ruruha.
Hobaneng ho Hlophisoa Liphanele tsa Sandwich tsa Polyurethane (PIR)?
Har'a mefuta e fapaneng ea thepa ea mantlha ea ho thibela ho ruruha,polyisocyanurate (PIR)Liphanele tsa sandwich tse thehiloeng holim'a tsona li tsebahala haholo kaconductivity e tlase ea mocheso,ho bolelang hore li fana ka tšireletso e betere ka liphanele tse tšesaane. Sephetho ke ho sebelisa matla hantle, e leng sa bohlokoa bakeng sa:
- Libaka tsa polokelo e batang le lifeme tsa ho sebetsana le lijo
- Mehaho ea indasteri le ea khoebo
- Litsamaiso tsa marulelo le tsa ho koahela mabota
- Matlo a hahiloeng esale pele le meaho e tloaelehileng

Karolo eaLi-Catalyst tsa PolyurethaneTlhahisong ea Liphanele tsa Sandwich
Li-catalyst tsa polyurethane li bapala karolo eakarolo ea bohlokoatlhahisong ea liphanele tsa sandwich. Li-catalyst tsena li potlakisa karabelo lipakeng tsali-polyol le li-isocyanate,ho nolofalletsa ts'ebetso e laoloang ea ho fofonela le ho folisa e hlokahalang ho theha motheo oa PIR.
At Lisebelisoa tse Ncha tsa Mingxu, re fana ka mefuta e fapaneng ea li-catalyst tse khethehileng tsa polyurethane tse etselitsoeng lits'ebetso tsa panel ea sandwich, ho kenyeletsoa:
- MXC-T:Sesebediswa se tshepahalang sa ho kenya di-gelling se kgothaletsang dikarabelo tse potlakileng le tse tshwanang tsa urethane. Se thusa ho laola nako e sa thekeseleng mme se netefatsa sebopeho se setle sa foam nakong ya tlhahiso.
- MXC-C15:Sesebediswa se sebetsang haholo sa amine se tsebahalang ka ho ntlafatsa ho phekolwa ha bokaholimo le phallo ya foam. Se nolofalletsa botsitso bo betere ba boholo mme se fokotsa diphoso tsa bokaholimo.
- MXC-37:E etselitsoe lits'ebetso tse nang le mosi o fokolang le tse sebetsang hantle, sesebelisoa sena sa ho thusa ho ntlafatsa phallo ea metsi 'me se netefatsa ts'ebetso e ntle ea ho thibela ho ruruha ea phanele e felileng.
Hammoho, di-catalyst tsena di netefatsataolo e leka-lekaneng ea karabelo, ho phahama ha foam ka mokhoa o ts'oanang,leboleng bo tsitsitseng ba ho thibela ho ruruha, ho fihlela maemo a holimo a hlokahalang thepa ea kaho ea sejoale-joale.
