Forula ya molekile:C₃H₈O
Isopropyl Alcohol (IPA) ni igikoresho cy’ingenzi kandi gifite ubushobozi bwinshi, ahanini gikora nk'umusemburo mwiza kandi kikaba igikoresho cy’ingenzi mu nganda. Nk'umusemburo, Isopropyl Alcohol ni ingenzi cyane kubera imbaraga zayo zo gukuraho amavuta no guhumeka vuba. Ni ingenzi cyane mu miterere y’imiti yica udukoko, imiti isukura intoki, isuku y’ikoranabuhanga, n’imyambaro. Uretse uruhare rwayo nk'umusemburo, Isopropyl Alcohol ikora nk'ikintu cy’ingenzi mu guhuza ibinyabuzima, cyane cyane mu gukora acetone n’imiti itandukanye. Gukenera isuku nyinshi, cyane cyane mu bikoresho by’ikoranabuhanga no mu buvuzi, bigaragaza akamaro kayo. Yaba ikoreshwa nk'ikintu kivura indwara cyangwa nk'umusemburo wo gusukura neza no guhuza imiti, Isopropyl Alcohol iracyari igice cy’ingenzi mu nganda, kubungabunga no kubungabunga isuku ku isi yose. Ubwiza bwayo buhoraho n'itangwa ryayo ryizewe ni ingenzi ku bikorwa remezo by’inganda n’ubuzima rusange ku isi.

Styrene yo mu rwego rw'inganda: Ikintu cy'ingenzi mu gukora Resin
Forula ya molekile: C8H8
Styrene ni igikoresho cy'ingenzi cya peteroli na monomer ya polymer ikoreshwa cyane mu nganda mpuzamahanga. Iki gikoresho cy'amavuta kidafite ibara kandi gisobanutse neza gifite impumuro nziza ntigishongesha mu mazi ariko gishobora kuvangwa n'ibintu byinshi bivangwa n'ibinyabuzima, bigatuma styrene iba igikoresho cy'ingenzi mu gukora pulasitiki. Nk'igice cy'ingenzi, styrene ikoreshwa cyane cyane mu gukora polystyrene, resin ya ABS, na rubber ya sintetike, bigatuma habaho udushya mu gupakira, kubaka no mu bijyanye n'imodoka. By'umwihariko, styrene ikunze kugaragara mu bushyuhe bw'icyumba, bityo imiti nka hydroquinone ni ingenzi mu kubika no gutwara ibintu mu buryo bwizewe. Kubera imiterere yayo ihamye ya shimi n'uburyo ikoreshwa mu buryo bwagutse, styrene ikomeje kuba inkingi ikomeye mu nganda zigezweho za polymer, ishyigikira urusobe rw'inganda zitandukanye ku isi.

Cyclohexanone yo mu rwego rwo hejuru: Umushongi ukoreshwa mu nganda ukoreshwa mu buryo butandukanye
Forula ya molekile:C₆H₁₀O
Cyclohexanone ni ikintu cy'ingenzi cyane mu bimera gikoreshwa cyane nk'umusemburo mwiza cyane mu nganda. Imbaraga zayo zidasanzwe zituma iba nziza cyane mu gukora uruhu rw'ubukorano, gutunganya irangi rya polyurethane, no gukora irangi ryandika, aho ituma habaho ubwumvikane bwiza no gufatana neza. Uretse uruhare rwayo nk'umusemburo, cyclohexanone ni ingenzi cyane mu gukora imiti, cyane cyane mu gukora imiti yica ibyatsi, imashini zihutisha imirasire, n'imiti imwe n'imwe. Iyi mikorere ibiri nk'umusemburo w'ingenzi n'umusemburo w'ibanze bigaragaza akamaro kayo mu nzego zitandukanye z'inganda, bigatuma habaho udushya n'ubwiza mu bicuruzwa bya nyuma.

Igiciro cyiza cy'umukozi aside oxalic CAS：144-62-7
Aside ya Oxalic ni aside ikomeye ya dicarboxylike iboneka mu bimera byinshi n'imboga, akenshi ikaba ari umunyu wayo wa kalisiyumu cyangwa potasiyumu. Aside ya Oxalic ni yo yonyine ishoboka aho amatsinda abiri ya karboxylike ahurizwa hamwe; kubera iyo mpamvu aside ya Oxalic ni imwe muri aside organic zikomeye cyane. Bitandukanye n'izindi aside za karboxylike (usibye aside formike), ihita ihinduka oxidized; ibi bituma iba ingirakamaro mu gufotora, gusiba, no gukuraho wino. Aside ya Oxalic ikunze gutegurwa hakoreshejwe gushyushya sodium formate na sodium hydroxide kugira ngo habeho sodium oxalate, ihinduka sodium oxalate hanyuma igaterwa na aside sulfuric kugira ngo haboneke aside oxalic free.
Ingano ya aside oxalic iri hasi cyane mu bimera byinshi n'ibiribwa bikomoka ku bimera, ariko hari ihagije mu mboga za epinari, chard na beetroot kugira ngo bivange calcium mu kwinjiza ibi bimera.
Ikorerwa mu mubiri binyuze mu ihinduka rya aside glyoxylic cyangwa aside ascorbic. Ntabwo ihinduka ahubwo isohoka mu nkari. Ikoreshwa nk'ikintu gisesengura kandi kigatuma igabanuka. Aside oxalic ni umuti w’uburozi karemano ukoreshwa mu kuvura udukoko twa varroa mu matsinda y’udukoko tudafite/tudafite abana, udupaki, cyangwa amatsinda y’udukoko. Aside oxalic ivamo umwuka ikoreshwa na bamwe mu bavumvu nk'umuti wica udukoko twa Varroa duterwa n’udukoko. -
Igiciro cyiza cy'umukozi Xanthan Gum CAS yo mu rwego rw'inganda: 11138-66-2
Xanthan gum, izwi kandi nka Hanseonggum, ni ubwoko bwa exopolysaccharide ya mikorobe ikorwa na Xanthomnas campestris hamwe na karubohidrati nk'ibikoresho by'ingenzi (nk'ibinyampeke by'ibigori) binyuze mu buhanga bwo gushyushya. Ifite rheology yihariye, ishonga neza mu mazi, ihamye mu bushyuhe n'aside base, kandi ihura neza n'ubwoko butandukanye bw'imyunyu. Nk'ikintu gikomeza ubushyuhe, icyuma gihagarika, gitera imbaraga, gishobora gukoreshwa cyane mu biribwa, peteroli, ubuvuzi n'izindi nganda zirenga 20, ubu ni cyo gihingwa kinini ku isi kandi gikoreshwa cyane na mikorobe polysaccharide.
Xanthan gum ni ifu yimukanwa y'umuhondo woroshye kugeza ku wera, ihumura gato. Irashonga mu mazi akonje n'ashyushye, ifite umuti utagira aho ubogamiye, irwanya ubukonje cyangwa gushonga, ntishongera muri ethanol. Amazi akwirakwira, ahinduka ingano ihamye y'amazi.

Uruganda Igiciro Gishimishije DINP Urwego rw'inganda CAS：28553-12-0
Diisononyl phthalate (DINP):Iki gicuruzwa ni amazi abonerana kandi afite impumuro nke. Ni pulasitiki ikomeye ikoreshwa mu buryo butandukanye kandi ifite imiterere myiza. Iki gicuruzwa kirashongeshwa muri PVC, kandi ntikizangirika nubwo cyakoreshwa ku bwinshi. Guhindagurika kw'ikirere, kwimuka no kudahumanya ni byiza kurusha DOP (dioctyl phthalate), ishobora guha iki gicuruzwa ubushobozi bwo guhangana n'urumuri, kudashyuha, kudasaza no gukingira amashanyarazi, kandi imikorere yacyo yose ni myiza kuruta DOP. Kubera ko ibicuruzwa bikorerwa muri iki gicuruzwa bifite ubushobozi bwo guhangana n'amazi no gukurura amazi, uburozi buke, kudasaza, ubushobozi bwo kwirinda amashanyarazi, bityo kikaba gikoreshwa cyane mu gikinisho, insinga, insinga.
Ugereranyije na DOP, uburemere bwa molekile ni bunini kandi burebure, bityo bugira ubushobozi bwo gusaza neza, burwanya kwimuka, burwanya cairy, kandi burwanya ubushyuhe bwinshi. Mu buryo nk'ubwo, mu bihe bimwe, ingaruka za DINP zo gushushanya pulasitiki ni mbi gato kurusha DOP. Muri rusange abantu bemera ko DINP itangiza ibidukikije kurusha DOP.
DINP ifite akamaro mu kunoza inyungu zo gusohora. Mu gihe gisanzwe cyo gutunganya gusohora, DINP ishobora kugabanya ubushyuhe bwo gushonga bw'uruvange kurusha DOP, ibi bifasha kugabanya igitutu cy'icyitegererezo cy'umuyoboro, kugabanya kwangirika kw'imashini cyangwa kongera umusaruro (kugeza kuri 21%). Nta mpamvu yo guhindura formula y'ibicuruzwa n'uburyo bwo kubitunganya, nta shoramari ryinshi, nta ngufu z'inyongera zikoreshwa, no kubungabunga ubuziranenge bw'ibicuruzwa.
Ubusanzwe DINP ni amazi y'amavuta, ntashongesha mu mazi. Muri rusange itwarwa n'amato, indobo nto z'icyuma cyangwa utudomo twa pulasitiki twihariye.
Kimwe mu bikoresho by'ingenzi bya DINP -INA (INA), ubu ni amasosiyete make gusa ku isi ashobora gukora, nka Exxon Mobil ya Leta Zunze Ubumwe za Amerika, isosiyete yatsindiye mu Budage, isosiyete ya Concord yo mu Buyapani, na sosiyete yo muri Aziya y'Epfo yo muri Tayiwani. Kuri ubu, nta sosiyete n'imwe ikora INA mu gihugu. Inganda zose zikora DINP mu Bushinwa zose zisabwa kuva mu bicuruzwa bitumizwa mu mahanga.
