Zeolite molecular sieves ni gaw, lai wa sai shaning ni hta, plastic hpaga lam hta, n-gun n rawng hkra galaw ya ai ni hku nna, grai myit lawm wa sai. Dai ni hpe laksan hku nna, hkrat sum ai lam ni hpe pat shingdang na matu hte nbung n-gun hpe jat ya ai majaw, magam bungli prat hpe galu shangun ai.
PVC Zeolite n-gun ja ai
PVC gaw shingra tara hku nna katsi ai hpe hkam sha chye ai, katsi ai hpe n kaja ai, katsi ai aten hta hten za chye ai. PVC arung arai ni a n-gun yawm mat ai, nsam galai mat ai, jak rung arung arai ni hpe n sum mat hkra makawp maga na matu thermal stabilizers ni ra ai.
PVC gaw katsi ai hte hkrum katut ai shaloi hydrogen chloride hpe shapraw kau ya ai majaw, PVC a nsam nsam nsam hpraw mat nna, bungli galaw ai lam hta mung hkra machyi mat ai direct factor rai nga ai. Dai majaw, thermal stabilizers ni gaw hydrogen chloride a n-gun n rawng ai lam hte n-gun n rawng ai lam hpe pat shingdang na matu lit nga ai.
Zeolite molecular sieves ni gaw hydrogen chloride hpe hkap la lu ai atsam nga ai, dai hta n-ga, calcium (sh) zinc stabilizers ni hte mung rau jawm galaw lu ai majaw PVC a nbung n-gun yawng hpe jat ya lu ai, PVC a shawng nnan na nsam galai mat ai hte aten galu-asak kaba wa ai manghkang ni hpe mung gram lajang ya lu ai.
PP Zeolite ngang grin ai
PP gaw oxidation, thermal cracking, shing nrai nhtoi hte n-gun yawm mat ai majaw, antioxidants hte heat stabilizers ni hpe jat bang ra ai. Grau nna, hpring tsup ai masterbatches hte bai jai lang ai arung arai ni hta, n san seng ai arung arai ni (hka, acid) ni gaw, n kaja ai lam hpe lawan ladan galaw ya na re.
Zeolite molecular sieves gaw PP system hta ngam nga ai hka hpe hkap la nna, galaw shapraw ai lam hpe grau kaja hkra galaw ya ai, peroxides hte organic acid zawn re ai acidic n san seng ai ni hpe hkap la nna antioxidant atsam hpe jat ya ai, kaga additives ni hte mung rau jawm galaw nna, katsi ai hte oxygen hpe shalai ya ai hpe pat shingdang ya lu ai majaw, PP a service life hpe galu kaba shangun lu ai.
PP stabilizers (sh) PP composite a fillers ni hku nna, molecular sieves ni gaw n htawt sit ai (sh) n-gun n rawng ai, nbung n-gun kaja ai, inorganic fillers (sh) additives ni hte kayau nna PP arung arai ni a bungli hpe grau kaja hkra galaw mai ai.
PVC/PP ngang grin ai jak ni a matu Zeolite n-gun rawng ai hka htung ni
PVC/PP n-gun shayawm ai tsi ni a matu lang mai ai zeolite molecular sieve ni hta A, P, X hte Y amyu ni lawm ai.Raitim, A molecular sieve (ga shadawn. 4A zeolite powder) gaw jai lang ai akyu hte manu jahpu-htuk manu ai majaw grau htuk manu ai.
3A zeolite molecular sieve: PVC (sh) PP system ni hta hka hpe hkap la na matu hka hpe hka ja ai tsi hku nna lang chye ai. PP system ni hta lawt lu ai acid ni hpe (oxidative degradation hku nna byin pru wa ai trace acid zawn re ai) ni hpe rim la lu ai hta mung, n-gun langai ngai nga ai.
Type 4A zeolite molecular sieve: PVC n-gun shayawm ai jak ni hta, hydrogen chloride a n-gun kaji ni hpe hkap la nna, n-gun shayawm ai lam ni hpe pat shingdang ya ai hte n-gun shayawm ai lam hpe grau kaja hkra galaw ya ai. PP stabilizers ni hta, hka hte acidic n san seng ai lam ni hpe hkap la nna, galaw shapraw ai lam hta ngang grin ai lam hpe jat ya nna, hten za ai lam hpe shayawm ya ai.
Type 5A zeolite molecular sieve: PVC galaw ai shaloi pru wa ai hydrogen chloride hte n san seng ai molecule ni hpe hkap la nna, madung hku nna hkap la lu ai atsam hte nbung katsi ai hpe hkam sharang lu ai atsam hpe jat ya na matu jai lang ai.
13X zeolite molecular sieve amyu: Dai gaw grau kaba ai hka hpe hkap la lu ai atsam nga ai rai nna, hka hpe hkap la lu ai, hka hpe hkap la lu ai. Dai hpe madung hku nna PVC additive system langai ngai hta (sh) n-gun rawng ai stabilizer hpe htaw ai hku nna lang ai.
