SUNNYJOINT kommenta ka sebopeho sa plastiki sebakeng sa lipapali sa sekolo se ka ho khatholla mele ea motho
Shenyang SUNNYJOINT joaloka moemeli oa Rubber Additives, ka lilemo tse 'maloa tse fetileng, track ea polasetiki e se e amanang haholo le litekanyetso le libapali. Le fa ho ntse ho na le tlaleho e ncha e reng "track ea polasetiki e tla lokolla me gase e kotsi" e sokelisitsi batho. Ka lebaka la litlaleho tsena, litekanyetso li lemositsoe hore li se ke tsa lula track ea polasetiki nako e telele, 'me libaka tse ngata li sitisiwe ho qhomisa runway e ntse e tsoela pele, 'me likolo tse ling li nahana ho senya track ea polasetiki e theko e phahameng. Ho latela tlhaloso ea moqolotsi, boholo ba likolo tse ka sehloohong le tse sekondari Beijing, Shanghai le Guangzhou li se li lokisitsoe ka libaka tsa polasetiki. Likolo tse 'maloa tse nang le maemo a matle li na le lipapali tse fetang tse peli tsa polasetiki. Mesebetsi e mengata, track ea polasetiki e se e fetohile sesebediswa se hlokahalang le maemo a tekanyo bakeng sa libaka tsa sechaba.
So, is it really toxic to use such a wide plastic track? Where does the toxicity start? In this regard, our reporter interviewed the production companies of plastic track, academic experts and authoritative organizations in the industry.
Mokhatlo oa li-catalyst le Professor Li Baoshan, motsamaisi oa Khemistri ho Beijing University of Chemical Technology, e ne e le motsamaisi oa pele eo reporter a buileng le eena. Monahano oa hae ke hore ho tloha ho tlhahiso le sebopeho sa khemikhale sa sehlahisoa sa likarolo tsa polasetiki, ho na le menyetla ea ho baka tšenyo e itseng ho 'mele oa motho. Le fa e le joalo, kaha likarolo tsa polasetiki hangata li behiloe libakeng tse majaneng tse nang le moea o motle, monyetla ona ke o monyane.
He said from a professional point of view that the plastic track is generally made of a combination of organic molecules and inorganic fillers (calcium carbonate). Inorganic fillers are generally stable, and organic compounds are mostly composed of low molecular weights containing chlorine. Under sunlight irradiation and certain temperature conditions, the compounds may decompose and may cause some harm to the human body after decomposition. In addition, in order to make the product more stable, at the same time soft and elastic, some additives need to be added during the processing, mainly sulfide-based antioxidants, which may become harmful substances under certain environmental conditions, causing respiratory tract. And skin diseases.
Mokhatlo oa China oa thepa e sa fetoheng, mookameli oa Laboratori ea Tlhahlobo ea Rubble ea Sechaba sa Boithabiso sa China, le Profesa Chen Jianding oa Sekolo sa Saense le Theknoloji ea thepa ea Univesithi ea East China ba na le maikutlo a tšoanang. Nakong ea puisano ka mohala le mecha ea phatlalatso, o boletse hore haeba lebopo la polasetiki le hlahisa monko, ka mokhoa oa maikutlo, mohlomong ha se ho lekana le phetiso ea kemik'hale nakong ea ts'ebetso ea thepa ea lebopo la polasetiki, kapa thepa ea toluene e kenngoa bakeng sa kaho ea lebopo la polasetiki. Le fa ho ntse ho le joalo, ho tloha ka lilemo tsa hae tsa liphuputso, haholoholo eksibiteng ea tlhahlobo ea sehlopha sa litlhōrō tsa synthetic sa sebaka sa Tianxie, ha ho na a hu e 'ngoe e lumelang ho hlahisoa ha mosi oa toxic ho tsoa lebopong la polasetiki.
Kamora ho fumana potso ea moqolotsi, Ma Zhenzhu, moqolotsi oa Sehlopha sa Tjusto le Lihlahisoa sa China Academy of Building Materials Science, moqolotsi oa Setsi sa Naha sa Tjusto ea Lihlahisoa tse Ahiloeng, le moqolotsi oa Setsi sa Naha sa Ts'ebetso ea Indasteri ea Lebone le Tlhahlobo, o ile a boela a hlokomela plastiki tseo sehlopha se li entseng ka lilemo tsa morao tjena. Mohlahlobisisi o ile a joetsa meqolotsi ea litaba hore ho tsoa ho lifoto tsena tsa tlhahlobo, merero e meholo ea borai ba tikoloho eo batho ba e tšoenyang haholo, joalo ka formaldehyde le benzene, ha e so fumanoe, empa lihlahisoa tsa likhoebo tse itseng li fumanoe li le tlas’a maemo a phahameng a metal a boima joalo ka lead.
Mohlahlobi another, Xin Haobo, motsamaisi wa Functional Polymer Research Institute of Qingdao University of Science and Technology, o ile a boela a rialo ho boraihan, hore sebaka se tšepahalang sa polasetiki se ke ke sa ama 'mele oa motho sebakeng se bulehileng. O ile a re: karolo e ka sehloohong ea polasetiki e tla nyane e futhumetse gase ea toluene diisocyanate ka letsatsi kapa mocheso o mofuthu. Le fa substance ena e na le toxin, palo ea volatilization e nyenyane haholo. Sebakeng se bulehileng, boleng ba concentration ka kakaretso bo sitwa ho fihla 'meleng oa motho. Bokhoni ba phello.
Ho latela toxicology ea track e entsoeng ka polasetiki ho feta ho ba le borai ba litsebi, 'me karabelo ea k'hamphani ea tlhahiso e ntse e le matla haholo. Baoding Great Wall Synthetic Rubber Co., Ltd ke e 'ngoe ea baetsi ba baneng ba kholo ka ho fetisisa ba tlhahiso ea track e entsoeng ka polasetiki China. Wang Xianwen, molaoli e moholo oa khamphani, o itse ka puisano ka mohala le moqolotsi ena hore ho na le mehlala e mengata le formula bakeng sa track e entsoeng ka polasetiki, joalo ka k'hamphani e etellang pele, ho tsoa ho lik'hamphani tse ngata.
Ho latela mekhoa ea tlhahiso ea selemo, ha feela e na le ts'ebetso e nonnetseng, mokhoa oa sayense, le haholoholo e nepahetseng, e ke ke ea bakela kotsi ho bophelo bo botle. Hona joale, 'mala oa' 'me o hlahisa' 'emoheng ke ho tšoenyeha ha sechaba ka 'marakeng oa litsela tse entsoeng ka polasetiki le ts'ireletso ea sehlahisoa, empa sena se statement se ntse se latsoa ebile se ama tlhahiso le thekiso ka mokhoa o tebileng. Seo se khoptjoang ke hore indasteri ha e so bone motheo o amanang le litsela tse entsoeng ka polasetiki tse chesang.
