Polystirene ni imwe muri plastiki zikoreshwa cyane.Kwagura polystirene, thermoplastique, gushonga iyo bishyushye kandi bigahinduka bikomeye iyo bikonje.Ifite ubushyuhe buhebuje kandi burambye bwo gukonjesha, kwihanganira umwihariko no kurwanya ihungabana, kurwanya gusaza no kwirinda amazi, bityo yagiye ikoreshwa cyane mubice bitandukanye nko kubaka, gupakira, ibikoresho bya mashanyarazi na elegitoronike, amato, ibinyabiziga no gukora indege, ibikoresho byo gushushanya, no kubaka amazu.ikoreshwa cyane.Kurenga 50% muribo ni ibikoresho bya elegitoroniki n’amashanyarazi bikurura ibikoresho, udusanduku tw’amafi n’ibikomoka ku buhinzi n’ibindi bikoresho bibika bishya, byorohereza ubuzima bwacu.
Gukora amavuta ya EPS - inzira nyamukuru mu nganda
Mubisanzwe uburyo bwo kubumba EPS burimo intambwe zingenzi zikurikira: mbere yo kubira ifuro → gukiza → gushushanya.Mbere yo kumurika ni ugushira amasaro ya EPS muri barri yimashini ibanziriza flashing, hanyuma ukayishyushya hamwe na parike kugeza yoroshye.Umuti ubira ifuro (mubisanzwe 4-7% pentane) ubitswe mumasaro ya EPS utangira kubira no guhumeka.Gazi ya pentane yahinduwe yongerera umuvuduko imbere mumasaro ya EPS, bigatuma yaguka mubunini.Mu muvuduko wemewe wo kubira ifuro, igipimo gikenewe cyo kubira ifuro cyangwa uburemere bwa garama ya garama irashobora kuboneka muguhindura ubushyuhe mbere yo kwaguka, umuvuduko wamazi, ingano y'ibiryo, nibindi.
Ibibyimba bishya byavutse byoroshye kandi bidakomeye kubera guhindagurika kwa agent ifuro hamwe no guhuza ibintu bisigaye byifuro, kandi imbere biri mumyuka kandi byoroshye kandi bidakomeye.Kubwibyo, hagomba kubaho igihe gihagije kugirango umwuka winjire muri micropores imbere mubice byinshi kugirango uburinganire bwimbere ninyuma.Muri icyo gihe, ituma ibice bifatanye bifatanye bigabanya ubushuhe kandi bigakuraho amashanyarazi ahamye asanzwe yegeranijwe no guterana kwinshi.Iyi nzira yitwa gukira, mubisanzwe bifata amasaha agera kuri 4-6.Amasaro yabanje kwagurwa no gukama yimurirwa mubibumbano, hanyuma hongewemo amavuta kugirango amasaro ahuze, hanyuma akonje hanyuma aramanuke kugirango abone ibicuruzwa byinshi.
Urashobora kuboneka mubikorwa byavuzwe haruguru ko amavuta ari isoko yingirakamaro yingufu zumuriro kugirango EPS ibe ifuro.Ariko gushyushya amavuta hamwe no gukonjesha umunara wamazi nabyo ni ingenzi cyane mu gukoresha ingufu no guhuza ibyuka bihumanya ikirere.Hariho ubundi buryo bukoreshwa neza muburyo butandukanye bwo guhuza ifuro rito ridakoresheje amavuta?
Umuyoboro wa elegitoroniki ya elegitoroniki ushonga, itsinda rya Kurt Esa (nyuma bita "Kurt") ryaturutse mu Budage ryatanze igisubizo cyabo.
Ubu bushakashatsi bwikoranabuhanga hamwe niterambere ryiterambere bitandukanye nuburyo gakondo bwamazi, bukoresha umurongo wa radio mugushyushya.Gushyushya radiyo ni uburyo bwo gushyushya bushingiye ku kintu cyo gukuramo ingufu za radiyo no kuyihindura ingufu z’ubushyuhe, ku buryo umubiri wose ushyuha icyarimwe.Intandaro yo kubimenya ni dielectric ihinduranya umurima.Binyuze mu muvuduko mwinshi wo gusubiranamo wa molekile ya dipole imbere mu mubiri ushyushye, "ubushyuhe bwo guterana imbere" butangwa kugirango ubushyuhe bwibintu bishyushye.Hatabayeho uburyo bwo gutwara ubushyuhe, imbere no hanze yibikoresho birashobora gushyuha.Gushyushya icyarimwe no gushyushya icyarimwe, umuvuduko wo gushyushya urihuta kandi umwe, kandi intego yo gushyushya irashobora kugerwaho gusa nigice cyangwa kimwe cya cumi cyingufu zikoreshwa muburyo busanzwe bwo gushyushya.Kubwibyo, iyi nzira idahwitse irakwiriye cyane cyane gutunganya amasaro yagutse hamwe na polarike ya molekulari.Kubuvuzi bwibikoresho bitari inkingi harimo amasaro ya EPS, birakenewe gusa gukoresha inyongeramusaruro zikwiye.
Mubisanzwe, polymers irashobora kugabanywamo polar polymers na polymers itari polar, ariko ubu buryo bwo gutondekanya ni rusange kandi ntabwo byoroshye kubusobanura.Kugeza ubu, polyolefine (polyethylene, polystirene, nibindi) byitwa cyane cyane polymers itari polar, na polymers zirimo amatsinda ya polar mumurongo wuruhande bita polar polymers.Muri rusange, irashobora gucirwa urubanza ukurikije imiterere yitsinda ryimikorere kuri polymer, nka polymers ifite amide amide, amatsinda ya nitrile, ester group, halogène, nibindi ni polar, mugihe polyethylene, polypropilene na polystirene Nta matsinda ya polar ihari. kumurongo uringaniye, polymer nayo ntabwo ari polar.
Nukuvuga ko uburyo bwo gukora radiyo yumuriro wa electromagnetic yumurongo wa radiyo gushonga bikenera amashanyarazi numwuka gusa, kandi ntibikeneye gushyiraho sisitemu ya parike cyangwa igikoresho cyo gukonjesha amazi yo mu kibaya cyamazi, cyoroshye kandi cyoroshye, kandi kizigama ingufu kandi kirengera ibidukikije .Ugereranije nuburyo bwo kubyara ukoresheje amavuta, irashobora kuzigama 90% yingufu.Mugukuraho icyifuzo cyo gukoresha amavuta namazi, ukoresheje Kurtz WAVE FOAMER irashobora kuzigama litiro miliyoni 4 zamazi kumwaka, ibyo bikaba bihwanye no gukoresha amazi buri mwaka byibuze byibuze abantu 6.000.
Usibye kuzigama ingufu no kurengera ibidukikije, amashanyarazi yumuriro wa radiyo yumurongo wa elegitoronike ashobora no kubyara ibicuruzwa byiza cyane.Gusa ikoreshwa rya electromagnetic waves mumirongo yumurongo irashobora kwemeza gushonga neza no gukora uduce duto duto.Mubisanzwe, ibyangombwa bisabwa byumuvuduko wamazi ni mwinshi cyane ukoresheje uburyo bwa parike gakondo, bitabaye ibyo bizatuma ibicuruzwa bigabanuka kandi bito kuruta ubunini bwateganijwe nyuma yo gukonja.Bitandukanye no guhinduranya amavuta, igabanuka ryibicuruzwa byakozwe na electromagnetic yumurongo wa radiyo yumurongo wo gushonga bigabanuka cyane, ituze ryikigereranyo riratera imbere kuburyo bugaragara, hamwe no kwinjiza amavuta yibice bya furo hamwe nubushuhe bwasigaye hamwe nifuro yabyimbye mubibumbano biterwa na kondegene. byagabanutse cyane.Video, reka tuyibone hamwe!
Byongeye kandi, tekinoroji ya radiyo yo gushonga itezimbere cyane igipimo cyo kugarura ibikoresho byifuro.Mubisanzwe, gutunganya ibicuruzwa biva mu ifuro bikorwa haba muburyo bwa shimi cyangwa imiti.Muri byo, uburyo bwo gutunganya imashini bukoreshwa ni ugukata no gushonga mu buryo butaziguye, hanyuma ukayikoresha mu gutegura ibikoresho bito bitunganijwe neza, kandi ibikoresho bikunze kuba munsi ya polymer y'umwimerere (Ishusho 1).Molekile ntoya yabonetse noneho ikoreshwa nkibikoresho fatizo kugirango bategure uduce dushya.Ugereranije nuburyo bwa mashini, ituze ryimyanya mishya mishya iratera imbere, ariko inzira ifite ingufu nyinshi nigipimo gito cyo gukira.
Dufashe urugero rwa plastike ya polyethylene, ubushyuhe bwangirika bwibi bikoresho bugomba kuba hejuru ya 600 ° C, kandi igipimo cyo gukira kwa monyle ya Ethylene kiri munsi ya 10%.EPS ikorwa nuburyo gakondo bwamazi irashobora gutunganya kugeza kuri 20% yibikoresho, mugihe EPS yakozwe na tekinoroji ya radiyo yumurongo wa radiyo ifite igipimo cyo gutunganya 70%, gihuye neza nigitekerezo cy "iterambere rirambye".
Kugeza ubu umushinga wa Kurt "Gutunganya imiti idafite ibikoresho bya EPS na Radio Frequency Fusion Technology" yatsindiye igihembo cy’ingufu za Bavariya 2020.Buri myaka ibiri, Bavariya iha igihembo ibihembo byindashyikirwa mu bikorwa by’ingufu, kandi igihembo cy’ingufu cya Bavariya kikaba kimwe mu bihembo bihebuje mu rwego rw’ingufu.Kuri iyi ngingo, Rainer Kurtz, umuyobozi mukuru wa Kurtz Ersa, yagize ati: “Kuva yashingwa mu 1971, Kurtz yakomeje kuyobora iterambere ry’inganda zikora ifuro, kandi akomeza guteza imbere inzira zirambye kugira ngo atange umusanzu urambye ku isi; .Umusanzu.Kugeza ubu, Kurtz yateje imbere inganda zitandukanye ziyobora inganda zemewe.Muri byo, Kurtz WAVE FOAMER - tekinoroji yo gutunganya amaradiyo ya radiyo ya radiyo, ntabwo ikiza ingufu gusa kandi yangiza ibidukikije, ariko kandi ishobora no kubyara ifuro ryiza cyane, ryahinduye rwose Umusaruro w’ibicuruzwa gakondo, bituma ejo hazaza h'icyatsi. yo gutunganya ifuro rirambye ”.
Kugeza ubu, tekinoroji ya Kurt ya radiyo ya Kurt yatangiye gukora ibicuruzwa byinshi bya EPS.Mu bihe biri imbere, Kurt arateganya gukoresha iri koranabuhanga mu bikoresho byangirika ndetse n'ibikoresho bya EPP.Mu nzira yiterambere rirambye, tuzagenda tujya kure hamwe nabakiriya bacu.
