Silicone roj yog cov organic silicon compound, cov kua pob tshab uas muaj cov kab los yog cyclic dimethyl polysiloxane, nrog zoo heev nto nro thiab kub stability. Silicone roj yog dav siv hauv chemistry, electronics, textiles, lubrication thiab lwm yam kev lag luam.
Lub luag haujlwm ntawm silicone roj hauv polyurethane mos ua npuas ncauj yog:
1. Optimizing lub pore qauv
Raws li lub pore stabilizer, silicone roj tuaj yeem qhia tau rau hauv kev npaj ntawm polyurethane mos ua npuas ncauj, synergistically nrog foaming tus neeg sawv cev los txhawb cov tiam ntawm cov roj, thiab tuaj yeem kho qhov pore loj thiab ntom thaum tsim lub qhov hws, kom lub pore txheej txheem ntau dua. thiab ruaj khov, yog li optimizing lub pore qauv ntawm polyurethane mos ua npuas ncauj.
2. Txhim kho qhov pore stability
Thaum lub sij hawm npaj ntawm polyurethane mos ua npuas ncauj, silicone roj tuaj yeem hnov mob nrog isocyanate lossis polyol hauv cov khoom siv ua npuas ncauj los tsim cov qauv sib txuas nrog muaj zog affinity rau polyurethane molecules. Cov qauv no tuaj yeem txhim kho qhov ruaj khov ntawm qhov pores, tiv thaiv qhov pore rupture thiab txawm tias polymer decomposition, thiab thaum kawg txhim kho lub cev ntawm cov khoom ua npuas ncauj.
3. Txhim kho lub cev muaj zog ntawm cov npuas dej mos
Vim qhov sib ntxiv ntawm cov roj silicone rau polyurethane mos ua npuas ncauj, lub cev ntawm cov khoom ua npuas ncauj tuaj yeem txhim kho. Qhov sib ntxiv ntawm cov roj silicone tuaj yeem txhim kho qhov ntom ntom thiab elastic modulus ntawm cov ntaub mos mos, ua kom lub zog ruaj khov thiab ruaj khov ntawm cov npuas dej, thiab ua rau cov polyurethane mos ua npuas ncauj muaj kev ua haujlwm zoo dua thaum siv.
Raws li feem ntau siv additives, silicone roj yog dav siv nyob rau hauv polyurethane mos ua npuas ncauj. Qhov sib ntxiv ntawm cov roj silicone tuaj yeem ua kom zoo dua qhov pore qauv ntawm polyurethane mos ua npuas ncauj, txhim kho lub pore stability thiab txhim kho lub cev lub cev ntawm mos ua npuas ncauj. Yog li ntawd, daim ntawv thov ntawm silicone roj nyob rau hauv polyurethane mos ua npuas ncauj tsis tau tsuas yog txhim kho qhov zoo ntawm cov khoom, tab sis kuj coj ntau zog impetus rau txoj kev loj hlob ntawm kev lag luam.
