Kev Siv
Pentaerythritol feem ntau yog siv rau hauv kev lag luam txheej. Nws tuaj yeem siv los tsim cov alkyd resin coatings, uas tuaj yeem txhim kho qhov tawv, ci ntsa iab thiab ruaj khov ntawm cov zaj duab xis txheej. Nws kuj tseem siv ua cov khoom siv raw rau rosin esters uas xav tau rau cov xim pleev xim, cov varnishes thiab cov number case luam ntawv, thiab tuaj yeem siv los ua cov roj qhuav, cov txheej smoldering thiab cov roj nplua nyeem aviation. Tsis tas li ntawd, nws kuj tseem siv rau hauv kev tsim tshuaj, tshuaj tua kab thiab lwm yam khoom. Lub molecule pentaerythritol muaj plaub pawg hydroxymethyl sib npaug thiab muaj qib siab ntawm symmetry. Yog li ntawd, nws feem ntau siv ua cov khoom siv raw rau kev npaj cov tshuaj polyfunctional. Nitrification ntawm nws tuaj yeem tsim pentaerythritol tetranitrate, uas yog lub zog tawg; esterification tuaj yeem tau txais pentaerythritol triacrylate, uas yog siv ua txheej. Nws kuj tseem siv tau ua cov nplaim taws retardant rau cov nplaum. Thaum ua ke nrog ammonium polyphosphate, ib qho intumescent nplaim taws retardant tuaj yeem tau txais. Nws kuj tseem siv ua tus neeg sawv cev crosslinking rau polyurethane los muab cov saw hlau hauv polyurethane.
Ntim thiab Xa Khoom
Ntim: 25 / kg,Cov hnab yas woven lossis cov hnab ntawv kraft lossis raws li cov neeg siv khoom xav tau.
Kev xa khoom: yog cov tshuaj lom neeg thiab tuaj yeem xa los ntawm tsheb ciav hlau, dej hiav txwv thiab huab cua.
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
