Muraho, barwanyi b’ibidukikije, abakunzi b’ibikoresho byo mu gikoni, n’undi wese wigeze areba ibikoresho biri inyuma y’ibintu bya buri munsi! Wigeze wibaza uburyo imifuka yawe ukunda yo kubikamo ibiryo ishobora kongera gukoreshwa igumana ishusho yayo, cyangwa ni iki kirimo gukora cyane inyuma y’ibishushanyo kugira ngo agasanduku k’ibiribwa gafite isura nziza ka PVC gakomeze kuba gashya? Injira mu bikoresho bikomeza calcium zinc, intwari zitazwi cyane zihindura isi ya PVC imwe imwe. Reka dufungure laboratwari ya chimie turebe icyatuma ibi bikoresho biba ibya mbere mu nganda zigezweho!

Ikipe y'Inyenyeri zose iri mu bwoko bwa Molekuli

Tekerezaibintu bitera imbaraga zinc muri kalisiyumunk'ikipe y'inzozi z'intwari z'ibinyabutabire, buri munyamuryango azana ubuhanga budasanzwe mu rugamba. Mu by'ingenzi, izi mpumekezo zivanga karusiyamu na zinki karubokisilate - tekereza ko ari abakapiteni b'ikipe - hamwe n'imbaraga zishyigikiwe - gutera imbere nka polyols, amavuta ya soya ya epoxidized, antioxydants, na fosfite organic. Ni nko guteranya itsinda aho buri munyamuryango afite uruhare rwihariye, kuva ku mitsi kugeza ku bwonko!

Karubokisilate ya kalisiyumu na zinc ni byo bintu bikomeye birwanya ikibazo gikomeye cya PVC: kwangirika guterwa n'ubushyuhe. Polyols zikora nk'ingabo zirinda amahoro, zigabanya amakimbirane yose ya molekile mu gihe cyo gutunganya. Amavuta ya soya yakuwemo ogisijeni? Ni umufasha mwiza ku bidukikije, yongeraho uburyo karemano mu gihe yongera ubusugire. Kandi antioxydants? Ni abarinzi bari maso, birinda radicals zitagira ingaruka mbi zigerageza kwangiza ishyaka. Bafatanyije, bakora itsinda rya molekile Avengers, biteguye kurokora PVC kwangirika.

Gukingira ubushyuhe bwa pulasitiki yawe, Molekuli imwe icyarimwe

Tekereza ibi: Uri kurambura ifu ya pizza mu itanura rishyushye. Ubushyuhe bwinshi, irashya; irashya gato, kandi irashya. PVC ihura n'ikibazo nk'icyo mu gihe cyo kuyikora. Ubushyuhe bwinshi ni ingenzi mu kuyihinduramo ibintu byose kuva ku macupa y'amazi kugeza ku gupfunyika, ariko iyo idafite uburinzi bukwiye, PVC ishobora guhinduka akajagari gakomeye kandi kadahindagurika.

Aho niho ibipimo by'ubushyuhe bya kalisiyumu byinjira mu mpande nk'iz'ubushyuhe. Mu gihe cyo gusohora, gukoresha inshinge, cyangwa gukoresha uburyo bwo gusohora, ibi bipimo by'ubushyuhe bitangira gukora. Bikorana n'ibice bidakomeye bya molekile za PVC, bikarinda kwangirika no kurekura ibintu byangiza. Ingaruka zabyo ni izihe? PVC yawe – yatumye amarido yo kwiyuhagira aguma akomeye, imiyoboro y'ubusitani bwawe irinda kwangirika ku zuba, kandi ibikoresho byawe by'ibiribwa bigumana imiterere yabyo, nubwo byuzuyemo ibisigazwa bishyushye.

Ifite umutekano, irasesenguye - IsukuAmahitamo

Mu isi aho "ibiri imbere ari ingenzi," ibintu bitera imbaraga mu kubungabunga calcium zinc ni ingenzi mu kurinda umutekano. Bitandukanye n'ibintu bisanzwe bitera imbaraga mu kubungabunga ibidukikije bitanga ibimenyetso by'uburozi, aba bantu ni abantu beza. Ni abanyamaboko make - bakomeye mu kurwanya uburozi, bigatuma baba aba mbere mu kugura ibintu birushaho kuba byiza mu biribwa byacu.

Tekereza kuri ibi: iyo ufashe agafuka k'ibirayi cyangwa ugasuka amazi mu icupa rya pulasitiki, uba ushaka kumenya ko ipaki yawe idategura kukwihisha. Ibikoresho bigabanya ubushyuhe bya calcium zinc ntabwo byujuje gusa amahame agenga umutekano w'ibiryo, ahubwo binatsinda ikizamini cyo guhumeka - mu by'ukuri! Ntabwo bizahumanya ibyo kurya byawe n'impumuro idasanzwe cyangwa ngo bishyire mu biryo byawe imiti idakenewe. Byongeye kandi, niyo mpamvu ibikoresho byawe bya pulasitiki bisukuye biguma bisukuye, bigaragaza ibyo urya mu gihe bibikomeza ari bishya kandi bitekanye.

Imbunda y'ingabo z'Ubusuwisi yo mu Isi y'Ibipfunyika

Izi mashini zituma amazi adahindagurika si imwe gusa - amafarashi y'amayeri; ni zo mashini zikora ibintu byinshi ku isi ya PVC. Injira mu iduka iryo ari ryo ryose ry'ibiribwa, uzahabona ibikorwa byazo byose. Amashuka yoroshye yo gupfunyika ibiryo? Reba neza. Bigumana foromaje yawe nshya kandi sandwiches zawe zifunze neza nta kubangamira ubworoherane. Amacupa y'amazi akomeye? Reba neza kabiri. Byongerera imbaraga no kuramba mu gihe bireba ko icupa riguma ridafite BPA - kandi ritekanye kunywerwa.

Ndetse n'agapfunyika gafata neza gatuma igice cy'ibisigazwa by'imyanda biribwa, gafite imbaraga nyinshi zituruka ku bikoresho bitera imbaraga za calcium zinc. Bifasha agapfunyika gufata neza bihagije kugira ngo umwuka utangire ariko bikureho byoroshye, bidasize ibisigazwa bifatana. Kandi ntitwibagirwe ibyapa bya PVC biri ku byo ukunda cyane—ibi bikoresho bituma amabara aguma meza kandi ibikoresho bigakomeza kubaho, ndetse no mu kajagari k'amaduka y'ibiribwa.

Ejo hazaza - InshutiKosora

Muri iki gihe aho ibidukikije biramba, ibintu bitera imbaraga mu kubungabunga ibidukikije birimo kalisiyumu zinc ni byo biri ku isonga. Bikozwe mu bintu birengera ibidukikije nk'amavuta ya soya akomoka ku bimera, ni intambwe igana ku nganda ziharanira ibidukikije. Bishobora kandi kongera gukoreshwa, bivuze ko ibikoresho byawe bya PVC bishobora kongera gukoreshwa aho kuziba imyanda.

Rero, ubutaha uzapfuka agafuka kawe gashobora kongera gukoreshwa cyangwa ukavanaho umupfundikizo w'icupa ryawe ry'amazi, fata ukuboko bucece ku ntwari nto zikora cyane imbere. Ibikoresho bikomeza kalisiyumu bishobora kutagaragara ku maso, ariko ingaruka zabyo ku buzima bwacu bwa buri munsi - no ku isi - ni nini cyane. Ni igihamya cy'uko ibintu byiza koko biza mu dupaki duto (twa molekile)!
