Polystyrene resins, lwm yam raw khoom, polymers, catalysts
Lub ntsiab Cheebtsam ntawm XPS rwb thaiv tsev board muaj xws li polystyrene resin, lwm yam raw khoom thiab polymers, uas yog tov los ntawm tshav kub thiab txhaj tshuaj catalysts, thiab ces extruded thiab nias rau hauv lub kawg rigid foam board.
Cov khoom muaj pes tsawg leeg
Polystyrene resin: Qhov no yog qhov tseem ceeb ntawm XPS rwb thaiv tsev board, uas muab cov qauv yas yooj yim thiab kev ua tau zoo.
Lwm cov ntaub ntawv raw: suav nrog qee cov khoom ntxiv thiab cov khoom siv ntxiv, uas yog siv los txhim kho lub cev thiab tshuaj lom neeg ntawm cov rwb thaiv tsev.
Polymers: Siv los txhim kho tag nrho cov khoom thiab ruaj khov ntawm cov ntaub ntawv.
Catalyst: Ua raws li catalyst thaum lub sij hawm cua sov txheej txheem, yooj yim rau molding thiab kho cov khoom.
Cov txheej txheem ntau lawm
Cov txheej txheem tsim khoom ntawm XPS rwb thaiv tsev board suav nrog cov kauj ruam hauv qab no:
Kev npaj cov khoom raw: polystyrene resin yog tov nrog lwm cov ntaub ntawv raw.
Cua sov thiab sib tov: Cov sib tov yog rhuab mus rau qhov tsim nyog kub kom cia cov ntaub ntawv raw kom yaj zoo.
Txhaj tshuaj catalyst: Txhaj catalyst thaum lub sij hawm cua sov txheej txheem los txhawb cov tshuaj tiv thaiv ntawm cov khoom.
Extrusion extrusion molding: Cov khoom siv molten yog nias tawm los ntawm extruder los tsim cov txheej txheem rwb thaiv tsev uas xav tau.
Kev ua kom txias thiab kho: Cov txheej txheem rwb thaiv tsev yog txias thiab kho kom tsim tau lub rooj tsav xwm XPS zaum kawg.
Cov yam ntxwv ntawm kev ua haujlwm:
XPS rwb thaiv tsev board muaj cov yam ntxwv ua haujlwm hauv qab no:
Kev nqus dej tsawg heev: Vim nws qhov kaw-cell honeycomb qauv, XPS daim hlau tsis nqus dej.
Tsawg thermal conductivity: Nws muaj cov thermal conductivity tsawg thiab muaj cov thermal rwb thaiv tsev zoo.
High compressive zog: siab compressive zog, muaj peev xwm tiv taus siab loj.
Anti-aging: Yuav luag tsis muaj kev laus decomposition nyob rau hauv ib txwm siv.
