Taw qhia rau polyurethane pu ua npuas ncauj
1. Kev ua kom zoo thaum tshav kub kub, thawj cov ntaub ntawv pov thawj;
2. Cov kev tua hluav taws ua tau raws li GB8624 chav kawm B1 refractory thiab American ASTM E 84 tus qauv;
3. Kev ua tau zoo nyob rau qhov chaw kub tsis tshua muaj qhov kub, xws li muaj zog compressive, tsis thermal conductivity thiab ruaj ntseg;
4. Txiav thiab shaping yuav ua tau raws li kev tsim cov qauv ntawm cov txheej txheem ntau txheej txheem nrog ntau yam tuab thiab xyuas kom zoo tsim;
5. Kev ntsuas kub muaj peev xwm tuaj yeem ncav tau; - 196 ° C mus rau + 196 ° C
Tswvyim ntawm polyurethane npuas ncoo
PIR yog cov ntaub ntawv keeb kwm pej xeem cov ntaub ntawv uas muab cov ntsiab lus ntawm kev ua kom muaj protein ntau los txhawb kev mob genomic / proteomic.The PIR, nrog kev koom tes nrog lwm cov koom haum, cov ntaub ntawv pir-international ntawm protein sequences (PSD), 250,000 cov nqaijrog.Qhov kev ua tau zoo ntawm PIR
PIR yog ib yam tshiab ntawm cov organic polymer rwb thaiv tsev cov ntaub ntawv, uas yog Isocyanate cob (Isocyanate) hauv polyether (Ployol) ua cov ntaub ntawv tseem ceeb, ua ke nrog cov catalyst, hluav taws kub retardant thiab environment-friendly foaming agent, cov mis tshwj xeeb thiab cov txheej txheem nruj nyob rau hauv qhov kev ntsuas ntawm qhov sib xyaw, ua rau lub cev ua kom sov, ua rau lub cev ua kom sov ua kom sov, ua kom muaj hluav taws xob, ua kom muaj zog, ua kom muaj hluav taws xob zoo, Cov dej tsis muaj zog, qhov hluav taws xob tsis zoo, cov nplaim hluavtaws thiab qhov muag tsis pom zoo zoo zoo. Cov khoom siv high-tech organic polymer, cov hluav taws kub zoo, cov coefficient thermal conductivity, , yog siv nyob rau hauv cov ntaub ntawv pov thawj cov khoom hluav taws xob polymer thiab cov huab cua txias txias itable adiabatic kub ntau rau - 196 ° C mus + 120 ° C.
Daim ntawv thov kev kub ceev pu ua npuas dej
Cyanuric acid polyester npuas (PIR) raws li thoob ntiaj teb nyob rau hauv cov kab mob ntawm cov kab mob tshiab txias, nyob rau hauv European tsim lub teb chaws tau pib nyob rau hauv lub petrochemical zog engineering, kev tsim kho thiab ib puag ncig kev tiv thaiv thiab lub zog txuag nyob rau hauv cov chaw xws li dav siv nyob rau hauv peb lub teb chaws, PIR tsuas yog nyob rau hauv nws cov theem ntawm kev loj hlob, tsuas yog hauv LNG (165 ° C, liquefied natural gas) thiab kua ethylene (104 ° C) xws li roj thiab petrochemical thiab lwm qhov chaw tau siv.
