Yas Polystyrene (PS)
* Yas PS - polystyrene. Nws yog ib chav kawm ntawm cov yas suav nrog pawg styrene hauv cov saw hlau macromolecular, cov hom tseem ceeb suav nrog polystyrene dav dav (GPPS), polystyrene cuam tshuam siab (HIPS), polystyrene nthuav dav (EPS) thiab metallocene polystyrene (SPS) thiab lwm yam. Nws cov yam ntxwv tsis muaj xim, tsis muaj ntxhiab thiab tsis qab.
* Cov khoom yas PS customized
Polystyrene yog ib qho thermoplastic tsis muaj xim thiab pob tshab, cov polystyrene resin dav dav yog ib qho amorphous polymer, uas nthuav dav polystyrene feem ntau hu ua Styrofoam. Nws muaj qhov kub hloov iav siab dua 100 degrees Celsius, yog li nws feem ntau siv los ua ntau yam thawv pov tseg uas yuav tsum tau tiv taus qhov kub ntawm dej npau, xws li cov thawv styrofoam.
Koj tuaj yeem ua dab tsi nrog PS Yas?
PS muaj qhov pom tseeb zoo (qhov kis tau lub teeb ntawm 88% -92%) thiab qhov ci ntsa iab, yooj yim rau zas xim, siab tawv, zoo rigidity, ntxiv rau, muaj kev tiv thaiv dej zoo, tiv thaiv tshuaj lom neeg thiab kev ua haujlwm ntws. Nws cov qhov tsis zoo tseem ceeb yog: brittle, tsis tshua muaj zog cuam tshuam, yooj yim rau kev ntxhov siab tawg, tsis tiv taus kub.
PS yog qhov qis tshaj plaws ntawm tus nqi tsim khoom ntawm cov yas, siv dav hauv cov khoom siv pov tseg. Nws yog siv dav hauv cov khoom siv pov tseg, xws li cov khoom siv hauv tsev pov tseg, cov ntawv sau thiab lwm yam khoom siv niaj hnub.

Cov yam ntxwv ntawm Polystyrene (PS)
* Nyob ntawm hom PS nws tuaj yeem raug cais ua "thermoplastic" lossis "thermoset". Lub npe muaj feem cuam tshuam nrog txoj kev uas cov yas teb rau cua sov. Cov khoom siv thermoplastic ua kua tag nrho ntawm lawv qhov chaw yaj (210-249 degrees Celsius hauv rooj plaub ntawm Polystyrene), tab sis lawv pib ntws ntawm lawv qhov chaw hloov iav (100 degress Celsius rau PS).
* Ib qho tseem ceeb ntawm cov thermoplastics yog tias lawv tuaj yeem raug cua sov mus rau lawv qhov chaw yaj, txias, thiab rov ua kom sov dua yam tsis muaj kev puas tsuaj loj. Hloov chaw hlawv, thermoplastics ua kua, uas tso cai rau lawv kom yooj yim txhaj tshuaj pwm thiab tom qab ntawd rov ua dua tshiab. Los ntawm qhov sib piv, cov yas thermoset yuav tsis rov ua kua thaum lawv "teem" rau hauv daim ntawv khov.
Cov khoom siv PS ua li cas?
Polystyrene (PS) yog npaj los ntawm kev sib xyaw ua ke (polymerization) cov txheej txheem xws li propriety polymerization, suspension polymerization, emulsion polymerization, ionic polymerization thiab lwm yam. Kev siv hauv kev lag luam yog ntau dua lub cev polymerization thiab suspension polymerization. Tam sim no kev tsim khoom lag luam ntawm PS series resins yog tsim los ntawm kev sib txuas ntxiv polymerization.
Cov PS resin uas tsim los ntawm polymerization muaj pob tshab zoo thiab cov khoom siv hluav taws xob, tab sis muaj qhov faib tawm ntawm cov molecular tsis sib xws, thaum lub sijhawm polymerization ncua vim qhov kub thiab txias yooj yim tswj, qhov kub ntawm cov tshuaj tiv thaiv yooj yim rau disperse, kev tsim cov PS resin muaj qhov faib tawm ntawm cov molecular hnyav sib xws, cov yam ntxwv ntawm kev ua tau zoo, tab sis cov khoom yuav tawm me me ntawm kev dispersion hauv cov khoom, thiab lwm yam.
