Zapulasitikiakhala mbali yofunika ya moyo wathu watsiku ndi tsiku.Pulasitiki imalowa pafupifupi mbali zonse za dziko lamakono, kuchokerakhitchini to zamagetsi, zida zamankhwalaku zipangizo zomangira.Komabe, nkhawa zomwe zikukulirakulira za kukhudzidwa kwa chilengedwe ndi mapulasitiki kwapangitsa kuti afufuze zinthu zina monga ma silicones.
Silicone ndi chinthu chopangidwa kuchokera ku silicon, chinthu chopezeka mwachilengedwe chomwe chimapezeka mumchenga ndi quartz.Lili ndi makhalidwe ambiri ofunikira, monga kukana kutentha kwakukulu, kusinthasintha ndi kukhazikika, zomwe zimapangitsa kuti zikhale bwino kwambiri m'malo mwa mapulasitiki muzinthu zosiyanasiyana.Kugwiritsiridwa ntchito kwake mu kitchenware, zamagetsi, zipangizo zachipatala ndi zomangira zakhala zikuchulukirachulukira.
Chimodzi mwazofunikirazotsatira za chilengedwezinthu zapulasitiki ndi kuipitsidwa ndi zinyalala.Pulasitiki imatenga zaka mazana ambiri kuti awole, zomwe zimapangitsa kuti zinyalala ziwunjikane m'malo otayirako ndikuwononga nyanja zathu ndi mitsinje yamadzi.Kumbali inayi, zinthu za silicone zimakhala ndi zotsatira zochepa pa chilengedwe chifukwa zimakhala zolimba kwambiri ndipo zimatha kugwiritsidwanso ntchito.Kuphatikiza apo, ma silicones ndi ochezeka kutayira pansi ndipo amawola kukhala zinthu zopanda vuto monga silika ndi carbon dioxide.
Palinso nkhawa kuti mankhwala omwe ali muzinthu zapulasitiki amatha kulowa muzakudya ndi zakumwa.Phthalates ndi bisphenol A (BPA) ndizowonjezera zomwe zimagwiritsidwa ntchito popanga pulasitiki ndipo zimalumikizidwa ndi nkhawa zaumoyo.Mosiyana ndi izi, zinthu za silikoni zimatengedwa ngati chakudya ndipo sizitulutsa mankhwala owopsa akakumana ndi chakudya kapena zakumwa.Izi zimapangitsa silikoni kukhala chisankho chotetezeka cha zophikira, kuwonetsetsa kuti palibe zinthu zomwe zitha kuipitsa chakudya chathu.
Mu zamagetsi, kukhudzidwa kwa chilengedwe kwa pulasitiki kumawonekera pakukula kwavuto la e-waste.Zipangizo zamagetsi zimakhala ndi zigawo zapulasitiki zomwe zimakhala zovuta kuzibwezeretsanso ndipo nthawi zambiri zimakhala m'malo otayiramo kapena zotenthetsera.Silicone imapereka yankho lokhazikika chifukwa cha kulimba kwake komanso kukana kutentha kwambiri.Imatha kupirira zovuta ndipo ndiyosavuta kuyikonzanso kuposa pulasitiki, kuchepetsa kulemedwa kwa chilengedwe chonse chokhudzana ndi zinyalala zamagetsi.
Zida zamankhwala ndi gawo lina lomwe likuchulukirachulukira kukhala silikoni.Zigawo za pulasitiki m'zida zamankhwala zitha kubweretsa zoopsa monga kusamvana komanso kutayikira kwa zinthu zovulaza m'thupi.Silicone, kumbali ina, ndi biocompatible, yopanda poizoni komanso hypoallergenic, zomwe zimapangitsa kukhala chisankho choyamba pazachipatala.Kukhoza kwake kupirira kutsekereza mobwerezabwereza kumawonjezeranso kukopa kwake.
Zikafika pazinthu zomangira, mapulasitiki amagwiritsidwa ntchito kwambiri chifukwa cha kusinthasintha kwawo, kukwanitsa kwawo komanso kulemera kwawo.Komabe, zida zomangira pulasitiki zimatulutsa zinyalala zambiri panthawi yopanga ndikutaya.Silicone imapereka njira ina yosamalira zachilengedwe chifukwa imatha kubwezeretsedwanso, yokhazikika komanso yopatsa mphamvu.Makampani akuwunika kwambiri kugwiritsa ntchito zida za silicone pomanga kuti achepetse kuwonongeka kwa chilengedwe komwe kumakhudzana ndi mapulasitiki.
Pomaliza, pali kusiyana kwakukulu pakukhudzidwa kwa chilengedwe chasilicone ndi zinthu zapulasitiki.Ngakhale kuti zinthu zapulasitiki zimayambitsa kuipitsa, kusonkhanitsa zinyalala komanso ngozi zomwe zingawononge thanzi, ma silicones amapereka yankho lokhazikika.Kukhalitsa kwake, kubwezeretsedwanso komanso chilengedwe chosakhala ndi poizoni kumapangitsa kuti chikhale chosinthika m'malo osiyanasiyana m'mafakitale osiyanasiyana monga khitchini, zamagetsi, zida zamankhwala ngakhalenso zomangamanga.Pamene dziko likufuna kuchepetsa zovuta za pulasitiki, kutengera zinthu za silikoni kumatha kutenga gawo lofunikira pomanga tsogolo lobiriwira.
