Siv cov khoom pov tseg ua npuas dej ua cov khoom siv thermal rwb thaiv tsev
Nrog rau txoj kev loj hlob ntawm kev lag luam tshuaj, polystyrene ua npuas ncauj tau tig los ntawm kev siv los ua cov khoom ntim, cov ntaub ntawv pov tseg, thiab lwm yam mus rau lub tshav pob ntawm cov ntaub ntawv rwb thaiv tsev nrog ntau lub khw muag khoom. Lub defoamed pov tseg polystyrene ua npuas ncauj yog ntxiv rau ib koob tshuaj uas tsis tshua muaj boiling kua modifier, foaming agent, catalyst, stabilizer, thiab lwm yam., thiab polystyrene hlaws yuav pre-foamed los ntawm cua sov, thiab ces rhuab nyob rau hauv lub pwm Ib rigid polystyrene ua npuas ncauj. board nrog nplua kaw pores tau npaj. Lub rooj tsavxwm no tuaj yeem siv ib leeg, lossis nws tuaj yeem muab qhwv nrog nyias nyias phaj tom qab tsim los ua ib lub rooj tsavxwm aluminium-yas. Nws cov thermal rwb thaiv tsev ua tau zoo heev, thiab nws tau raug sim los ntawm kev siv tiag tiag ntawm lub ru tsev ntawm lub tsev. Yog li ntawd, tsis muaj Frost thiab condensation tshwm sim, thiab qhov project tus nqi yuav raug txo, thiab kev tsim kho thiab kev ua haujlwm tau yooj yim. Yog li ntawd, nyob rau sab qaum teb cua sov cheeb tsam, polystyrene ua npuas ncauj rwb thaiv tsev board ua los ntawm cov qauv no muaj ntau yam kev siv thiab kev loj hlob zoo.
Kev npaj cov txheej txheem dej tsis zoo los ntawm khib nyiab Foamed yas
Siv cov khoom tsim nyog los hloov cov khoom pov tseg ua npuas ncauj tuaj yeem npaj cov dej-emulsion waterproof coatings uas ceev ceev-qhuav ntawm chav tsev kub thiab tiv taus dej ntev. Cov txheej txheem yog yooj yim nyob rau hauv tus txheej txheem, thiab nws kuj yog heev yooj yim mus kho lub viscosity nrog dej. Cov txheej txheem dej tsis zoo tuaj yeem siv rau cov thawv corrugated es tsis txhob ya raws cov roj pov thawj, thiab tseem tuaj yeem siv rau kev tiv thaiv dej ntawm fiberboard.
Siv cov khoom pov tseg ua npuas ncauj los tsim p-nitrobenzoic acid
P-nitrobenzoic acid (PNBA) feem ntau yog siv rau hauv kev tsim cov fibers muaj zog, tshuaj tua kab, dyes, resins, hlau nto xeb inhibitors, tshuaj pleev thaiv hnub, xim zaj duab xis couplers thiab lim thiab lwm yam khoom. Cov khib nyiab yas tuaj yeem tau txais los ntawm nitrification thiab oxidation. Kev siv cov qauv no muaj qhov zoo ntawm qhov yooj yim ntawm cov khoom siv raw, cov txheej txheem yooj yim thiab muaj txiaj ntsig ntxiv ntawm cov khoom, thiab tsim nyog rau kev nce qib hauv cov tuam txhab hauv nroog.
Siv cov khoom pov tseg ua npuas ncauj kom tawg los tsim styrene
Muaj 3 txoj hauv kev los tsim cov styrene los ntawm kev tawg ntawm cov khib nyiab yas, uas yog thermal cracking, catalytic cracking thiab anaerobic catalytic cracking, thiab thaum kawg cov khib nyiab npuas yas tuaj yeem hloov mus rau styrene, ib qho tseem ceeb ntawm cov khoom siv raw.
Tam sim no, kev siv thev naus laus zis ntawm cov khoom siv pov tseg yog niaj hnub tshawb nrhiav thiab tsim tawm. Kev siv cov khib nyiab pov tseg los hloov kho cov khoom siv hauv tsev tsim nyog tau txais kev saib xyuas ntau dua thiab tshawb nrhiav.
