Iplastiki yePolystyrene (PS)
* Iplastiki yePS - ipolystyrene. Ludidi lweeplastiki oluquka iqela lestyrene kwikhonkco le-macromolecular, iintlobo eziphambili ziquka i-general polystyrene (GPPS), i-high impact polystyrene (HIPS), i-expandable polystyrene (EPS) kunye ne-metallocene polystyrene (SPS) njalo njalo. Iimpawu zayo azinambala, azinavumba kwaye azinancasa.
* Iimveliso zeplastiki zePS ezenziwe ngokwezifiso
I-Polystyrene yi-thermoplastic engenambala necacileyo, i-polystyrene resin esetyenziswa ngokubanzi yi-polymer e-amorphous, apho i-polystyrene ekhulisiweyo yaziwa ngokuba yi-Styrofoam. Inobushushu bokutshintsha kweglasi obungaphezulu kwe-100 degrees Celsius, ngoko ke idla ngokusetyenziselwa ukwenza iintlobo ngeentlobo zezikhongozeli ezilahlwayo ezifuna ukumelana nobushushu bamanzi abilayo, njengeebhokisi ze-styrofoam.
Yintoni onokuyenza ngePS Plastiki?
I-PS inokukhanya okuhle (isantya sokudlulisa ukukhanya yi-88% -92%) kunye nokukhazimla komphezulu, kulula ukuyidaya, ubulukhuni obuphezulu, ukuqina okuhle, ukongeza, kukho ukumelana kakuhle kwamanzi, ukumelana neekhemikhali kunye nokusebenza kakuhle kokucubungula. Iingxaki zayo eziphambili zezi: ukuqhekeka, amandla aphantsi okuchaphazeleka, ukuqhekeka okulula kokuxinezeleka, ukumelana nobushushu obuthathaka.
I-PS yeyona xabiso liphantsi kakhulu lemveliso yeplastiki, isetyenziswa kakhulu kwiimveliso ezilahlwayo. Isetyenziswa kakhulu kwiimveliso ezilahlwayo, ezifana nezitya zokutyela ezilahlwayo, kunye nezinto zokubhala nezinye izinto eziyimfuneko zemihla ngemihla.

Iimpawu zePolystyrene (PS)
* Ngokuxhomekeke kuhlobo lwe-PS, ingahlulwa njengezinto ezibizwa ngokuba yi-“thermoplastic” okanye “thermoset”. Eli gama linxulumene nendlela iplastiki esabela ngayo kubushushu. Izinto ezibizwa ngokuba yi-Thermoplastic ziba lulwelo ngokupheleleyo kwindawo yazo yokunyibilika (210-249 degrees Celsius kwimeko yePolystyrene), kodwa ziqala ukugeleza kwindawo yazo yokutshintsha iglasi (100 degress Celsius kwi-PS).
* Uphawu olubalulekileyo oluluncedo malunga nee-thermoplastics kukuba zinokufudunyezwa zide zifikelele kwinqanaba lazo lokunyibilika, zipholiswe, kwaye ziphinde zifudunyezwe kwakhona ngaphandle kokuwohloka okukhulu. Endaweni yokutsha, ii-thermoplastics ziyanyibilika, nto leyo evumela ukuba zifakwe ngokulula zize ziphinde zisetyenziswe. Iiplastiki ze-thermoset, ngokwahlukileyo, aziyi kuphinda zinyibilike xa "zibekwe" kwimo eqinileyo.
Zenziwa njani izinto zePS?
I-Polystyrene (PS) ilungiswa ngeendlela zokwenziwa (polymerization) ezifana ne-propriety polymerization, i-suspension polymerization, i-emulsion polymerization, i-ionic polymerization njalo njalo. Ukusetyenziswa kwemizi-mveliso kukwandisa i-body polymerization kunye ne-suspension polymerization. Ngoku imveliso yemizi-mveliso yee-resin ze-PS series iveliswa ngendlela ye-continuous polymerization.
I-resin ye-PS eveliswa yi-polymerization ineempawu zombane ezibonakalayo nezicacileyo, kodwa kukho ukusasazwa kobunzima be-molecular okufanayo, ngelixa i-polymerization yokumiswa ngenxa yobushushu kulula ukuyilawula, ubushushu bokusabela kulula ukuyisasaza, imveliso ye-resin ye-PS inokusasazwa kobunzima be-molecular obufanayo, iimpawu zokusebenza okubanzi, kodwa imveliso iya kushiya inani elincinci lokusasazeka kwimveliso, njl.
