Tekinoroji yemazuva ano yemasandwich panel uye zvinhu zve polyurethane core
Sechinhu chitsva chakakosha muindasitiri yekuvaka, mapaneru esandwich epolyurethane ave chinhu chinodiwa pakugadzira maindasitiri, nzvimbo inotonhorera, maworkshop akachena nedzimwe zvivakwa. Izvi zvinhu zvine zvidimbu zviviri zvemapaneru esimbi uye pakati pe polyurethane foam zvinotsamira zvakanyanya pahurongwa hwehunyanzvi hwe polyurethane catalyst nekuda kwekushanda kwayo kwakanaka. Ma catalyst edu eMXC series akagadzirwa zvakanyanya kuti agadzire mapaneru esandwich, izvo zvinogona kuvandudza zvakanyanya kunaka kwechigadzirwa uye kushanda zvakanaka kwekugadzira.
Sisitimu yeCatalyst yemapaneru esandwich
Mabhenefiti akasiyana eMXC-37 (DMAEE)kataviridzi
MXC-37 (2-(2-(dimethylamino)ethoxy)ethanol, CAS 1704-62-7) chinhu chinobatsira zvikuru mukugadzira sandwich panels:
- Hunhu husina kunhuhwirira, husina kunhuhwirira kwakanyanya: kugadzirisa dambudziko rekunhuhwirira kwemaamine catalysts echinyakare uye kugadzirisa mamiriro ekugadzira
- Kuburitsa furo rakawanda: zvinonyanya kukodzera mafomura ane mvura yakawanda kuti furo riwedzere kukura
- Maitiro ekushandisa kaviri: anogona kushandiswa ega sechinhu chikuru chinobatsira kana pamwe chete neBDMAEE
- Kuenderana kwakakura: kwakakodzera kune akasiyana ma polyester uye polyether polyol systems
Mumutsara wekugadzirwa kwesandwich panels, MXC-37 inogona kupa curve yakagadzikana yekuita kuti ive nechokwadi chekuti foam core material yakafanana uye yakafanana, izvo zvakakosha kuti pave nechokwadi chekuti flat uye divi rakagadzikana resandwich panels.
Kubudirira kwetekinoroji yeMXC-15(mushonga we potassium octanoate)
MXC-15 (CAS 3164-85-0), senzira inoshanda yekubvisa tsvina kubva mumafuta, inopa rutsigiro rwakakosha pakugadzirwa kwemapaneru esandwich ePIR:
- Kuchinja kwakanyanya kwazvo: kunokurudzira kutemwa kwe isocyanate uye kunovandudza kugadzikana kwekupisa kwe furo
- Inoshanda kune fomura ine viscosity yakakwira: inogadzirisa kufanana kwemvura uye maitiro ehurongwa hwakasimba hwezvinhu
- Inodhura uye inoshanda zvakanaka: huwandu hushoma hwekuwedzera hunogona kuita kuti pave nemhedzisiro yakanaka yekukonzera matambudziko
- Sisitimu yePIR inoenderana nehunyanzvi: yakagadzirirwa zvakanyanya mapaneru esandwich epolyisocyanurate
MXC-15 inogona kuvandudza zvakanyanya kusimba kwemoto uye kugadzikana kwezvikamu zvemasandwich panels, kuitira kuti arambe achigona kuchengetedza hunhu hwakanaka hwemakanika munzvimbo dzinopisa zvakanyanya.
Basa guru rezvinokonzeresamukugadzirwa kwema sandwich panel
Mukugadzirwa kwemapaneru esandwich epolyurethane, sisitimu ye catalyst inokanganisa zvakananga zviratidzo zvepakati zvinotevera:
1. Kuyerera kwefuro: iva nechokwadi chekuti zvinhu zvakagadziriswa zvazadza nzvimbo iri pakati pemapaneru kudzivirira kushomeka kwezvinhu.
2. Kumhanya kwekugadzirisa: enzanisa zvinodiwa nekumhanya kwemutsara wekugadzira unoenderera mberi kuti uwedzere kugona kwekugadzira
3. Maumbirwo emasero: anokanganisa mafambiro ekupisa uye simba remakanika repaneru yesandwich
4. Kushanda kwekubatanidza: kunosarudza simba rekubatanidza pakati pechinhu chikuru nepaneru
5. Kugadzikana kwehukuru: kunodzivirira kushanduka kwepaneru kunokonzerwa nekuderera kwefuro
Chikwata chedu chehunyanzvi chinogona kupa mhinduro yakanakisisa yekuwedzera simba rekugadzira zvinhu zvakasiyana-siyana uye zvinodiwa nezvigadzirwa nekudzora zvakakwana chiyero cheMXC-37 neMXC-15, zvichibatsira vatengi kuwana:
- Wedzera kumhanya kwemutsetse wekugadzira ne20-30%
- Wedzera huwandu hwekukodzera chigadzirwa kusvika pamusoro pe98%
- Deredza kushandiswa kwesimba ne15-20%
- Kuchengetedza mari yakawanda pagore
Rutsigiro rwehunyanzvi hwehunyanzvi uye masevhisi
Isu tinopa rutsigiro rwehunyanzvi rwakakwana kune vagadziri vema sandwich panels:
- Sevhisi yekugadzirisa fomura: gadzirisa sisitimu ye catalyst zvichienderana nefomura iripo yemutengi
- Nhungamiro yeparamende yemaitiro: ipa tembiricha yakakwana yezvinhu, tembiricha yemukuvhuvhu uye mamwe mazano akakosha eparamende
- Kutangwa kwekambani yekugadzira: Vashandi vehunyanzvi vachatungamira kutanga kwekugadzira panzvimbo iyi
- Rutsigiro rwekuongorora mhando: Kubatsira mukugadzira sisitimu yekudzora mhando yakanaka
Wana ruzivo nezvechigadzirwa uye kubvunzana kwehunyanzvi
Tinokoka nemwoyo wese vagadziri vemasandwich panel kuti vadzidze zvakawanda nezvekushanda kwakanaka kweMXC series catalysts. Kana uchida ruzivo rwakadzama rwehunyanzvi kana kunyorera sampuro dzemahara, ndapota taura nesu uchishandisa nzira dzinotevera:
