Kwinkqubo yokuphinda kusetyenziswe iibhetri ze-lithium ze-ternary kunye neebhetri ze-lithium iron phosphate, i-sulfuric acid kunye ne-caustic soda ngokungenakuphepheka ziguqulwa zibe ziityuwa ze-sodium sulfate ngenxa yeemfuno zobuchwepheshe. Isisombululo esiluhlaza...

1. Intshayelelo Isanti ye-quartz ecociweyo, umgubo we-quartz, kukusetyenziswa kokucubungula i-quartz ore ecocekileyo kakhulu, imveliso inomgangatho ophezulu (SiO2=99.82%, Fe2O3=0.37, Al2O3=0.072, CaO=0.14), umbala omhlophe, ubunzima obuqinileyo (ii-Mohs degrees ezisixhenxe nangaphezulu...

1. Yintoni i-ammonia nitrogen? I-ammonia nitrogen ibhekisa kwi-ammonia ngohlobo lwe-ammonia ekhululekileyo (okanye i-non-ionic ammonia, i-NH3) okanye i-ionic ammonia (NH4+). I-pH ephezulu kunye nenxalenye ephezulu ye-ammonia ekhululekileyo; Ngokwahlukileyo koko, inxalenye ye-ammo...

I-Chelate, i-chelate eyenziwe zii-chelating agents, ivela kwigama lesiGrike elithi Chele, elithetha uzipho lwenkala. Ii-Chelates zifana neenzipho zenkala eziphethe ii-ion zesinyithi, ezizinzileyo kakhulu kwaye kulula ukuzisusa okanye ukuzisebenzisa ezi i-ion zesinyithi....

1. Iiasidi vitriolIfomula yemolekyuli i-H2SO4, ulwelo olunamafutha olungenambala okanye olumdaka, iarhente enamandla yokuxova, umatshini okonakalisayo ufunxa kakhulu, ukukhutshwa kobushushu okuninzi emanzini, i-asidi kufuneka yongezwe emanzini xa ixutyiwe, kwaye ...

I-Sodium carboxymethyl cellulose (CMC) yi-anionic chain, straight, water-soluble cellulose ether, i-derivative ye-cellulose yendalo kunye ne-chloroacetic acid ngokuguqulwa kweekhemikhali. Isisombululo sayo samanzi sinemisebenzi yokutyeba, ...

I-Sodium tripolyphosphate luhlobo lwekhompawundi engaphiliyo, umgubo omhlophe wekristale, onyibilikayo emanzini, isisombululo se-alkaline, yi-polyphosphate engqamanayo enganyibilikiyo emanzini. I-Sodium tripolyphosphate inemisebenzi yokuchela, ukumisa...

I-potassium chloride yikhompawundi engaphiliyo, ikristale emhlophe, ayinavumba, inetyuwa, ibukeka njengetyuwa. Inyibilika emanzini, kwi-ether, kwi-glycerin nakwi-alkali, inyibilika kancinci kwi-ethanol (ayinyibiliki kwi-anhydrous ethanol), i-hygroscopic, kulula ukuyibamba;...

Ishishini le-elektroniki. I-Selenium ineempawu ze-photosensitivity kunye ne-semiconductor, kwaye isetyenziswa rhoqo kwishishini le-elektroniki ukwenza ii-photocells, ii-photosensors, izixhobo ze-laser, abalawuli be-infrared, ii-photocells, ii-photoresistor, i-opt...

I-calcium chloride yahlulwe yaba yi-calcium chloride dihydrate kunye ne-calcium chloride engamanzi ngokweekristale eziqulathwe kuyo. Iimveliso zifumaneka ngomgubo, ii-flake kunye ne-granular form. Ngokweeklasi yahlulwe yaba yi-indu...

Indima ye-glacial acetic acid kwishishini lokuhlamba 1. Umsebenzi wokunyibilikisa i-asidi ekususeni amabala I-acetic acid njengeviniga yendalo, inokunyibilikisa i-tannic acid, i-fruit acid kunye nezinye iimpawu ze-organic acid, amabala engca, ijusi...

I-Aliphatic alcohol polyoxyethylene ether sodium sulfate (AES) yintlama yejeli emhlophe okanye etyheli ekhanyayo, enyibilikayo lula emanzini. Ineempawu ezintle zokucoca ukungcola, ukuxubha kunye nokukhupha amagwebu. Kulula ukubola, ukubola kwe-biodegradation deg...
