Indasitiri yemasandwich panel inoshandisa zvinhu zvinoshandisa simba repamusoro zvinopa kudzivirira kupisa, kudzivirira moto uye kugadzikana kwechimiro.MXC-5, MXC-8, MXC-41) inoita basa rakakosha mukugadzirwa kwezvinhu izvi, zvichibatsira kuwana mashandiro emakemikari nekukurumidza uye zvinobudirira mukugadzirwa kwefuro. Zvinhu zvinonyanya kushandiswa mu sandwich core zvinhu zvisina organic zvakaita se polyurethane (PUR), polyisocyanurate (PIR), polystyrene, phenolic foam (PF) uye rock wool. Pepa iri rinopa ruzivo rwezvinhu izvi uye kuti polyurethane catalysts dzinogona sei kubatsira mukugadzirwa nekushandiswa kwazvo muma sandwich panels.
Zvinhu Zvakajairika Zvekuzadza zveSandwich Panels
Zvinhu zvinoshandiswa muma sandwich panel cores zvinogona kukamurwa kuita zvikamu zviviri zvikuru: zvinhu zvakagadzirwa nefuro uye zvinhu zvisina kugadzirwa nefaibha. Rudzi rwechinhu chimwe nechimwe rune hunhu hwakasiyana hunoita kuti chikwanise kushandiswa zvakasiyana, zvichienderana nezvinodiwa nekupisa, chimiro, uye kudzivirira moto zvepaneru.
Zvinhu zveFuro
1. Polyurethane (PUR) uye Polyisocyanurate (PIR):
Polyurethane (PUR) nepolyisocyanurate (PIR) ndizvo zvinhu zviviri zvinonyanya kushandiswa mukugadzira mapaneru esandwich. Zvinhu izvi zvinogadzirwa nekuita kwepolyols uye isocyanates zvinokonzereswa nezvinhu zvakaita seMXC-5,MXC-8, uye MXC-41. Basa rekugadzira zvinhu zvinoita kuti furo riwedzere kukura, ripore uye ribatane zvinobudirira mukati mechimiro chesandwich plate.
- Kunamatira uye Kusimba kweMagadzirirwo:Chimwe chezvikonzero zvikuru zvekushandisa PUR/PIR muma sandwich panels ndechekuti ine hunhu hwakanaka hwekubatanidza. Munguva yekuputira furo, PUR nePIR zvinonamatira zvakanaka pazvinhu zvakaita sesimbi kana simbi yealuminium, zvichiita kuti pave nekusimba kwechimiro chepaneru. Hunhu uhwu hunoita kuti furo idzi dzive sarudzo yakakura yemitsetse yekuputira, sezvo chisungo chakasimba chakakosha kuti pave nekugadzikana.
- Kudzivirira Moto Kwakavandudzwa:Kugadzirwa kwemakemikari ePUR/PIR furo kwakavandudzika nekufamba kwemakore, pamwe chete nekudzivirira kwayo moto, chinhu chakakosha pakuvaka uko mitemo yakasimba yekuchengetedza moto inofanira kutevedzerwa. PIR, kunyanya, inodzivisa moto zviri nani pane PUR, zvichiita kuti ive sarudzo yakakura yekushandiswa kune njodzi huru.
2. Polystyrene (EPS/XPS):
Polystyrene, kusanganisira expanded polystyrene (EPS) uye extruded polystyrene (XPS), ndeimwe furo inoshandiswa muma sandwich panels. Kunyange zvazvo isingawanzo shandiswa sePUR/PIR, polystyrene inopa hunhu hwakanaka hwekudzivirira kupisa. Zvisinei, hunhu hwayo hwekunamira hahuna kusimba sePUR/PIR, saka ingasakodzera kushandiswa kunoda simba rakawanda rekuvaka.
- Kudzivirira Kupisa:Polystyrene inopa insulation yakanaka kwazvo yekupisa nemutengo wakaderera kana tichienzanisa nezvimwe zvinhu, zvichiita kuti ive sarudzo inozivikanwa kune mapurojekiti anonyanya kudhura. Zvisinei, haina simba rekudzivirira moto uye kubatana kunopihwa nePUR nePIR.
3. Foam yePhenolic (PF):
Foromu yePhenolic ichangobva kushandiswa kana tichienzanisa nezvimwe zvinhu zvefuro uye haiwanzo shandiswa mukugadzira sandwich panels. Zvisinei, ine mukana mumwe chete mukuru: inodzivisa moto zvakanyanya. Foromu yePhenolic ine simba rakanakisisa rekudzivirira moto pakati pezvinhu zvefuro, zvichiita kuti ikwanise kushandiswa uko kuchengetedzeka pamoto kuri iko kunonyanya kukosha.
- Kuramba Moto:Makemikoro akasiyana efoam yephenolic anoibvumira kutsungirira tembiricha yakakwira pasina kukanganisa kunaka kwechimiro chayo. Pasinei nekushanda kwayo zvakanaka pamoto, foam yephenolic haishandiswi zvakanyanya nekuda kwekudhura kwayo kwakanyanya uye kuwanikwa kwayo kushoma.
Zvinhu Zvisina Kugadzirwa zveFiber
1. Makushe eRock:
Uswa hweRockwool, chinhu chisina kugadzirwa nefiber, chinoshandiswa muma sandwich panel cores nekuda kwesimba rayo rekudzivirira moto uye kudzivirira ruzha. Kusiyana nezvinhu zvine furo, uswa hwedombo hahutsvi, zvichiita kuti ive sarudzo yakanaka yekushandisa pamoto.
- Kudzivirira Kupisa uye Ruzha:Rockwool inopa kudzivirira kupisa kunoshanda, kunyange zvazvo isina kukwirira sezvimwe zvinhu zvefuro. Uyezve, chimiro chayo chefiber chinobatsira kuderedza ruzha, zvichiita kuti ive yakakodzera kushandiswa kunoda kuderedza ruzha.
- Kuramba Moto:Chinhu chikuru chinobatsira Rockwool ndechekuti haitsvi. Inogona kutsungirira tembiricha yakakwira zvakanyanya, zvichiita kuti ive sarudzo inofarirwa nezvivakwa zvinoda dziviriro yakawedzerwa pamoto.
Basa rePolyurethane Catalysts mukugadzirwa kweSandwich Panel
Zvishandiso zvePolyurethane zvakaita seMXC-5, MXC-8, uye MXC-41 zvakakosha pakugadzirwa zvakanaka kwezvinhu zvefuro zvinoshandiswa mumasandwich panels. Zvishandiso izvi zvinokurumidzisa mashandiro emakemikari pakati pemapolyol nemaisocyanates, zvichiita kuti furo rikure zvakaenzana uye riporeswe zvinobudirira. Pasina zvishandiso, maitiro acho angave anononoka uye asina kukwana, zvichikonzera furo risina kunaka rine hunhu hwakakwana hwekubatanidza uye kudzivirira.
- Kudzora Kupindura:MaCatalyst anodzora mwero wekuumbwa kwefuro, zvichiita kuti furo riwedzere kukura kuti rizadze mukati mese wesandwich panel. Anobatsirawo pakuenzanisa pakati pema "blowing" uye "gelation reactions", zvichivandudza huwandu hwefuro uye chimiro chemasero.
- Kufunga Nezvezvakatipoteredza:Mazhinji ema "polyurethane catalysts" emazuva ano akagadzirwa kuderedza kuburitswa kwemhepo inoputika (VOC) uye kuvandudza kuchengetedzeka kwezvakatipoteredza. Ma "catalysts" asina kunhuhwirira kwakawanda, akadai seMXC-41, anobatsira mukugadzirwa kwema "sandwich panels" asingakuvadzi nharaunda.
Mhedziso
Mukugadzirwa kwema sandwich panels, kusarudza zvinhu zvakakodzera zvekuzadza kwakakosha kuti zvizadzise zvinodiwa pakupisa, chimiro, uye kuchengetedzwa kwemoto. Zvinhu zvakagadzirwa nefuro zvakaita sePUR, PIR, polystyrene, uye phenolic foam, pamwe chete nezvinhu zvisina kugadzirwa senge rockwool, chimwe nechimwe chine zvakanakira zvakasiyana. Polyurethane catalysts dzakadai seMXC-5, MXC-8, uye MXC-41 dzinoita basa rakakosha mukuona kuti zvinhu zvakagadzirwa nefuro zvinoshanda zvakanaka. Izvi zvinokatyamadza zvinokurumidzisa makemikari anogadzira furo, zvichipa hukama hwakanaka, kuputira kupisa, uye kudzivirira moto kwakakosha pakuvaka kwemazuva ano.
