1. Isingeniso Isihlabathi se-quartz esicwengisisiwe, i-quartz powder, ukusetshenziswa kokucubungula i-quartz ore okumsulwa okuphezulu, umkhiqizo unezinga eliphezulu (SiO2=99.82%, Fe2O3=0.37, Al2O3=0.072, CaO=0.14), umbala omhlophe, ubulukhuni obuqinile (Mohs degrees eziyisikhombisa noma ngaphezulu...

1. Iyini i-ammonia nitrogen? I-ammonia nitrogen ibhekisela ku-ammonia ngesimo se-ammonia yamahhala (noma i-non-ionic ammonia, i-NH3) noma i-ionic ammonia (NH4+). I-pH ephezulu kanye nengxenye ephezulu ye-ammonia yamahhala; Ngokuphambene nalokho, ingxenye ye-ammo...

I-Chelate, i-chelate eyakhiwe yi-chelating agents, ivela egameni lesiGreki elithi Chele, elisho uzipho lwenkala. Ama-Chelate afana nezinzipho zenkala eziphethe ama-ion ensimbi, azinzile kakhulu futhi kulula ukuwasusa noma ukuwasebenzisa la ma-ion ensimbi....

1. I-Acid vitriolIfomula ye-molecular H2SO4, uketshezi olunamafutha olungenambala noma olunsundu, i-oxidizing agent enamandla, umshini oqothulayo umunca kakhulu, inani elikhulu lokukhishwa kokushisa emanzini, i-asidi kumele ifakwe emanzini uma ixutshwe, futhi ...

I-Sodium carboxymethyl cellulose (CMC) iyi-anionic, i-straight chain, i-water-soluble cellulose ether, i-derivative ye-cellulose yemvelo kanye ne-chloroacetic acid ngokuguqulwa kwamakhemikhali. Isixazululo sayo samanzi sinemisebenzi yokujiya, ...

I-Sodium tripolyphosphate uhlobo lwenhlanganisela engaphili, i-white crystalline powder, encibilikayo emanzini, isixazululo se-alkaline, iyi-polyphosphate eqondile encibilikayo emanzini. I-Sodium tripolyphosphate inemisebenzi yokuchela, ukumiswa...

I-potassium chloride iyinhlanganisela engeyona engokwemvelo, ikristalu emhlophe, ayinaphunga, inosawoti, ibukeka njengosawoti. Incibilika emanzini, i-ether, i-glycerin kanye ne-alkali, incibilika kancane ku-ethanol (ayincibiliki ku-ethanol engenamanzi), i-hygroscopic, kulula ukuyibamba;...

Imboni ye-elekthronikhi I-Selenium inezakhiwo ze-photosensitivity kanye ne-semiconductor, futhi ivame ukusetshenziswa embonini ye-elekthronikhi ukukhiqiza ama-photocell, ama-photosensor, amadivayisi e-laser, abalawuli be-infrared, ama-photocell, ama-photoresistor, ama-photoresistor,...

I-calcium chloride ihlukaniswe ibe yi-calcium chloride dihydrate kanye ne-calcium chloride engamanzi ngokuya ngamanzi ekristalu aqukethwe. Imikhiqizo itholakala ngesimo sempuphu, i-flake kanye ne-granular. Ngokusho kwebanga ihlukaniswe yaba yi-indu...

Indima ye-glacial acetic acid embonini yokuwasha 1. Umsebenzi wokuncibilikisa i-asidi ekususweni kwamabala I-Acetic acid njengeviniga ephilayo, ingancibilikisa i-tannic acid, i-fruit acid nezinye izici ze-organic acid, amabala otshani, ijusi...

I-Aliphatic alcohol polyoxyethylene ether sodium sulfate (AES) iyi-gel paste emhlophe noma ephuzi ekhanyayo, encibilika kalula emanzini. Inezakhiwo ezinhle kakhulu zokususa ukungcola, i-emulsification kanye ne-foam. Kulula ukubola, i-biodegradation deg...

Amanzi amdaka ane-asidi yilawa manzi amdaka anenani le-pH elingaphansi kuka-6. Ngokwezinhlobo ezahlukene kanye nokuhlushwa kwama-asidi, amanzi amdaka ane-asidi angahlukaniswa abe amanzi amdaka ane-asidi engaphili kanye namanzi amdaka ane-asidi e-organic. Imfucuza enamandla ye-asidi...
