Cov tshuab luam ntawv yas no yog cov khoom sib zog yas pob tshab uas tsim los ntawm kev sib koom ua ke-polymerization ntawm styrene thiab acrylonitrile. Nws yog kev sib xyaw ua ke ntawm kev pom tseeb thiab nruj ntawm polystyrene nrog hardness, lub zog thiab hnyav tsis kam ntawm polyacrylonitrile.
Styrene-based cov ntaub ntawv muaj cov yam ntxwv zoo suav nrog kev ua haujlwm siab, kev ua haujlwm siab, kev nplua nuj ntawm kev tsim qauv, kev yooj yim ntawm kev tsim khoom thiab kev lag luam. SAN cov khoom lag luam muab kev nyiam huv, kev huv thiab kev nyab xeeb. Lawv kuj muab cov rwb thaiv tsev zoo thiab kuj tuaj yeem rov ua tau yooj yim.
Nws thiab siv feem ntau hauv tsheb, qhov teeb meem roj teeb, khoom siv hauv chav ua noj, khoom siv, rooj tog thiab khoom siv kho mob. Nws yog feem ntau siv nyob rau hauv qhov chaw ntawm polystyrene vim nws ntau dua thermal ua tau.
Cov khoom ntawm Styrene Acrylonitrile
SAN resins muaj kev siv zoo sib xws rau polystyrene. Zoo li polystyrene, lawv kuj tseem muaj qhov pom kev zoo, nkig thiab muaj kev coj tus yam ntxwv. Qee cov khoom theem pib uas cov khoom sib txuas polymer no yog raws li hauv qab no:
Siab lub zog thiab tshuaj lom neeg kuj
Muab qhov dej ntws zoo thiab qhov chaw ruaj khov
Heev tiv ntawm tshav kub
Cia nws ntws zoo
Tiv taus ntawm kev ntxhov siab tawg, roj, thiab khoom noj stains
Nws muaj iav txoj kev hloov pauv kub tshaj 100 ° C
Siv rau cov hom phiaj dav dav (cov neeg siv yas khoom kawg)
Lub cev nqaij daim tawv
Lub zog Tensile yog 3.40 - 3.90 N / mm Not thiab Notched Impact Strength yog 250 Kj / m²
