Abakhiqizi abaningi be-PS bakhiqiza amashidi e-polystyrene anobukhulu obungamafilamenti angu-40. Uma amashidi angu-50 esikwa ngesikhathi esisodwa, ubuso bomkhiqizo bunobukhazikhazi besilika (njengoba kuboniswe esithombeni), obungahlangabezani nezidingo zomkhiqizo. Njengoba umkhiqizo we-PS unokuqina okuhle, ezinye izithasiselo zingangezwa ukuthuthukisa ukuqina komkhiqizo.
Lapho ukhetha izithasiselo, kufanele kuqashelwe isisindo sama-molecule ezithasiselo, ukuthi ngabe isithwali siyahambisana yini ne-PS, kanye nomphumela wokuhlakazeka. Ngakho-ke, eziningiAbakhiqizi beshidi le-PSizonikeza kuqala izithasiselo ze-silicone.
Ngaphezu kokuthambisa, izithasiselo ze-silicone zingathuthukisa ukuhambisana kokuxhumana phakathi kwamaminerali angaphili angewona awe-polar kanye nezinto eziphilayo, ngaleyo ndlela zidlale indima ekumanziseni. Ngakho-ke, izithasiselo ze-silicone zabathwali be-PE zingaxazulula inkinga.
I-PS ne-PE ziyaxutshwa ngenani elincane. Akukho nkinga yokwengeza okungaphezu kuka-5% wesithwali se-PE ezintweni ze-PS. Ngakho-ke, kunconywa ukuthi amakhasimende engeze cishe u-1% kuya ku-3%, futhi kunezingxenye ezingaphili ezithasiselweni ze-silicone. Yi-silicon esikhuluma ngayo (lapha ibhekisela ku-silicon noma i-silicate, okungukuthi, i-silicon ezithasiselweni ze-silicone kanye ne-fiber yengilazi noma i-silicate ezithasiselweni ezingaphili, kanti izithasiselweni kuma-polymer cishe zonke ziyi-silicate), igoqwe ngezinto ze-polymer (i-polysiloxane) ngesakhiwo esihlanganisiwe, futhi amandla ayo aphakathi kwama-molecule anamandla kunalawo ama-polymer nezinto ezingaphili. Emakethe, izimboni eziningi zepulasitiki manje zisebenzisa izithasiselweni ze-polymer silicone ukuze zithathe indawo yezithasiselweni eziphansi zokugcoba zama-molecule. Umkhiqizo usebenza kahle, awunamvula, umelana nokushisa okuphezulu, futhi ngesikhathi esifanayo ushintsha ukumelana kwawo nokuguguleka. Ubulukhuni bungalungiswa futhi.
Ubuso beshidi le-PS elinezithasiselo ze-silicone bungathuthukiswa kakhulu, ukucwebezela nokuqina nakho kuyathuthukiswa, ukuqina kobuso bomkhiqizo kungcono, futhi kubushelelezi lapho kusikwa, futhi inkinga yokukhuhla ishidi le-PS iyaxazululwa.
Okuqukethwe
Njengoba eseneminyaka ecishe ibe ngu-20 embonini yemishini yokukhipha izinto ezihlakaniphile, ubelokhu ephethe izindima ezibalulekile eJwell Machinery, okuhlanganisa noMphathi Jikelele kanye noSihlalo Ojikelezayo. Kusukela ngo-2024, uphathe izinkampani eziningi ezingaphansi kwakhe, eqhuba ukwanda kwebhizinisi kanye nokuthuthukiswa kwezimboni, ngenkathi ehola ukusungula izinto ezintsha ekukhiqizeni izinto ezihlakaniphile kanye nokukhula komhlaba wonke.
