Polystyrene ifuro (EPS)

EPS ni polymer yoroheje.Bitewe nigiciro cyayo gito, nabwo ni ibikoresho bikoreshwa cyane mu murima wose wapakira, bingana na 60%.Amababi ya polystirene yakozwe mugushyiramo ibibyimba binyuze mbere yo kubira, gukiza, kubumba, kumisha, gukata nibindi bikorwa.Imiterere ya cavity ifunze ya EPS igena ko ifite ubushyuhe bwiza bwumuriro nubushyuhe buke bwumuriro.Ubushyuhe bwumuriro bwibibaho bya EPS muburyo butandukanye buri hagati ya 0.024W / mK ~ 0.041W / mK Ifite uburyo bwiza bwo kubika ubushyuhe ningaruka zo kubika ubukonje muri logistique.

Nyamara, nkibikoresho bya termoplastique, EPS izashonga iyo ishyushye kandi igakomera iyo ikonje, kandi ubushyuhe bwayo bwo guhindura ubushyuhe buri hagati ya 70 ° C, bivuze ko incubator ya EPS yatunganijwe mubipfunyika ifuro igomba gukoreshwa munsi ya 70 ° C.Niba ubushyuhe buri hejuru cyane, 70 ° C, imbaraga z'agasanduku zizagabanuka, kandi hazavamo ibintu bifite uburozi kubera guhindagurika kwa styrene.Kubwibyo, imyanda ya EPS ntishobora kuba ikirere gisanzwe, ntanubwo ishobora gutwikwa.

Mubyongeyeho, ubukana bwa EPS incubator ntabwo ari bwiza cyane, imikorere yo kuryama nayo ni rusange, kandi biroroshye kwangirika mugihe cyo gutwara, bityo ikoreshwa cyane mugukoresha rimwe, kubukonje bwigihe gito, intera ndende ubwikorezi bwurunigi, ninganda zibiribwa nkinyama ninkoko.Inzira n'ibikoresho byo gupakira ibiryo byihuse.Ubuzima bwa serivisi bwibicuruzwa mubusanzwe ni bugufi, hafi 50% byibicuruzwa bya Styrofoam bifite ubuzima bwumurimo wimyaka 2 gusa, naho 97% byibicuruzwa bya Styrofoam bifite ubuzima bwigihe kitarenze imyaka 10, bigatuma ifuro rya EPS rivaho umwaka ku mwaka, Ariko,EPS ifurontabwo byoroshye kubora no kuyitunganya, niyo mpamvu nyirabayazana w’umwanda wanduye muri iki gihe: EPS ifite ibice birenga 60% by’imyanda yera mu kwanduza inyanja!Nkibikoresho byo gupakira EPS, ibikoresho byinshi bya HCFC bifashisha mugukoresha ifuro, kandi ibicuruzwa byinshi bizaba bifite impumuro yihariye.Ubushobozi bwa ozone bushobora kugabanuka bwa HCFC bukubye inshuro 1.000 za dioxyde de carbone.Kubera iyo mpamvu, guhera mu myaka ya za 2010, Umuryango w’abibumbye, Amerika, Umuryango w’ubumwe bw’ibihugu by’Uburayi, Ubushinwa, Koreya yepfo, Ubuyapani n’ibindi bihugu (amashyirahamwe) n’uturere byemeje amategeko abuza cyangwa abuza ikoreshwa rya plastiki imwe rukumbi, harimo na Styrofoam , kandi abantu bashizeho ku gahato "Umuhanda wavuguruwe".
