Zeolite molecular sieves hian tun hnaiah plastics industry-a stabilizer angin ngaihven a hlawh hle a, polyvinyl chloride (PVC) leh polypropylene (PP) te hi a ni. Degradation reaction tihtawp nan leh thermal stability tihsan nan an hmang tlangpui a, chu chuan service life a ti rei thei a ni.
PVC Zeolite Stabilizer hmanga siam a ni
PVC hi a pianphungah chuan lumna lakah a sensitive a, thermal stability tha lo tak a nei a, temperature sang takah pawh a chhe thei hle. PVC material a chhe lo, a rawng a danglam lo, leh mechanical property a hloh loh nan thermal stabilizer a ngai a ni.
PVC hian lumna avanga hydrogen chloride a chhuah tir a, hei hi PVC rawng a dum a, a performance a tichhe theitu direct factor a ni. Chuvangin thermal stabilizers te hian hydrogen chloride neutrality leh chain degradation titawptu an ni.
Zeolite molecular sieves hian hydrogen chloride adsorb theihna a nei a, calcium emaw zinc stabilizers te nen pawh thawhhona tha tak neiin PVC thermal stability zawng zawng a tichak thei a, PVC initial discoloration leh long{0}}term aging problems te pawh a ti tha thei bawk.
PP Zeolite Stabilizer hmanga siam a ni
PP hi oxidation, thermal cracking, emaw photodegradation emaw a hlauhawm hle a, chuvangin antioxidants leh heat stabilizers te dah tel a ngai a ni. A bik takin filled masterbatch leh recycled material-ah chuan bawlhhlawh (tui, acid) te hian a chhe chak zawk ang.
Zeolite molecular sieves hian PP system-a tui awmsa chu a hip lut a, processing stability a ti tha a, acidic impurities peroxides leh organic acids te chu a absorb a, antioxidant property a ti sang a, additive dangte nen pawh thawhhona tha tak neiin heat leh oxygen transmission a block thei bawk a, chu chuan PP service life a ti rei thei bawk.
PP composite atanga PP stabilizer emaw filler emaw angin molecular sieves te hi migrate emaw volatilize emaw an ni lo va, thermal stability tha tak an nei a, PP materials te hnathawh that nan inorganic fillers emaw additives emaw nen an pawlh thei bawk.
PVC/PP Stabilizers atan Zeolite Molecular Sieves hman a ni
PVC/PP stabilizer atana hman theih zeolite molecular sieves te hi type A, P, X leh Y te an ni a, mahse, type A molecular sieve (eg. 4A zeolite powder) hi a hman dan leh a man tlawm zawk avangin a tha zawk a ni.
Type 3A zeolite molecular sieve: PVC emaw PP system-a tui awmte hip lut turin desiccant atan hman a ni fo. PP system-a free acid (oxidative degradation atanga lo chhuak trace acid ang chi) te man kawngah pawh nghawng engemaw chen a nei bawk.
Type 4A zeolite molecular sieve: PVC stabilizer-ah chuan hydrogen chloride molecule te te a hip lut a, degradation reaction a veng a, thermal discoloration a ti tha bawk. PP stabilizer-ah chuan moisture leh acidic impurities a absorb a, processing stability a ti sang a, degradation rates a ti tlem bawk.
Type 5A zeolite molecular sieve: PVC processing-a hydrogen chloride leh bawlhhlawh molecule chhuakte chu a absorb a, adsorption capacity leh temperature resistance tihchangtlunna atan hman a ni ber.
Type 13X zeolite molecular sieve: Adsorption capacity lian zawk a nei a, hydrogen chloride, sulphur dioxide leh acidic gas dangte a absorb thei bawk. PVC additive system bik emaw, composite stabilizer carrier atan emaw hman a ni tlangpui.
