Product Application
Inoshandiswa mukugadzira marara, mapurasitiki, uye mapolymers.
a) Kugadzirwa kwe: expandable polystyrene (EPS);
b) Kugadzirwa kwepolystyrene (HIPS) uye GPPS;
c) Kugadzirwa kwe styrenic co-polymers;
d) Kugadzirwa kweunsaturated polyester resins;
e) Kugadzirwa kwe styrene-butadiene rubber;
f) Kugadzirwa kwe styrene-butadiene latex;
g) Kugadzirwa kwe styrene isoprene co-polymers;
h) Kugadzirwa kwe styrene based polymeric dispersions;
i) Kugadzirwa kwema polyols akazadzwa.Styrene inonyanya kushandiswa semonomer kugadzira mapolymers (senge polystyrene, kana imwe rabha uye latex)
Styrene maleic anhydride (SMA kana SMAnh) i polymer yekugadzira iyo yakavakirwa-kumusoro ye styrene uye maleic anhydride monomers.Mamonomers anogona kunge akanyatso kuchinjika, achiiita alternating copolymer, [1] asi (random) copolymerization ine isingasviki 50% maleic anhydride yemukati inogoneka zvakare.Iyo polima inoumbwa neiyo radical polymerization, uchishandisa organic peroxide seyekutanga.Hunhu hukuru hweSMA copolymer chitarisiko chayo chakajeka, kupisa kwakanyanya kwekudzivirira, kugadzikana kwepamusoro-soro, uye kunyatsoitazve kwemapoka eanhydride.Iyo yekupedzisira ficha inoguma mukunyungudika kweSMA mune alkaline (mvura-yakavakirwa) mhinduro uye kupararira.
SMA inowanikwa muhuwandu hwakawanda hwemamorekuru huremu uye maleic anhydride (MA) zviri mukati.Mumusanganiswa wakajairwa wezviviri izvi zvivakwa, SMA inowanikwa sekristaro yakajeka granule inogona kushandiswa mumhando dzakasiyana dzekushandisa.SMA polymers ane huremu hwemamorekuru anoshandiswa zvakanyanya muinjiniya mapurasitiki ekushandisa, kazhinji mune yakagadziridzwa uye sarudzo yegirazi fiber izere akasiyana.Neimwe nzira, SMA inoiswa ichishandisa kujeka kwayo pamwe chete nezvimwe zvinhu zvakajeka sePMMA kana kupisa kwekudzivirira kupisa-kukwidza zvimwe zvinhu zvepolymers seABS kana PVC.Iko kunyungudika kweSMA mune alkaline mhinduro inoita kuti ive yakakodzera kune akasiyana maapplication mumunda we saizi (bepa), mabhainda, anoparadzira uye machira.Iyo chaiyo reactivity yeSMA inoita kuti ive yakakodzera mumiriri wekuenderana anowanzo asingaenderane mapolymers (semuenzaniso ABS/PA musanganiswa) kana kuyambuka-kubatanidza.Iyo tembiricha yekuchinja kwegirazi yeStyrene maleic anhydride ndeye 130 - 160 °C.
