Mawu Oyamba
Boric acid amatchedwanso "orthoboric acid". Amachokera ku mgwirizano pakati pa chilengedwe borax (sodium borate) ndi asidi. Chemical formula H3BO3. Kulemera kwa molekyulu 61.83. Mamba a triclinic oyera okhala ndi makristalo onyezimira. Kachulukidwe wachibale ndi 1.43514, ndipo refractive index ndi 1.337, 1.461, ndi 1.462. Zosungunuka m'madzi, ethanol Chemicalbook ndi glycerol. Njira yamadzimadzi ndi acidic ndipo ndi monovalent ofooka asidi (Ka = 6 × 10-10). Kusungunuka m'madzi kumawonjezeka ndi kutentha. Kutenthedwa mpaka 169 ℃ (± 1 ℃), kutaya madzi m'thupi kudzatulutsa metaboric acid, ndipo 300 ℃ ipanga boric anhydride. Neutralized ndi alkali wamphamvu kuti mupeze metaborate. Tetraborate imapezeka pansi pamikhalidwe yofooka ya alkaline.
Katundu
Njira yokonzekera: Hydrochloric acid kapena sulfuric acid akhoza kuwonjezeredwa ku borax solution, kapena angapezeke powola boraxite ndi hydrochloric acid. Kagwiritsidwe: Zomwe zimagwiritsidwa ntchito kwambiri popanga borate, galasi lamadzi, borate ester, galasi lamagetsi lamagetsi, enamel, utoto, pigment, zodzoladzola, zosungira zakudya, kutsirizitsa zikopa, kusindikiza ndi utoto zothandizira ndi mankhwala, etc. Ikhoza kugwiritsidwanso ntchito ngati antiseptic mankhwala ophera tizilombo toyambitsa matenda, astringent.
Malangizo
Moni, ndakondwa kukumana nanu pano. Kodi mumakonda malondawa? Izi ndikuziyika pamashelefu ndi ine. Ndikudziwa zambiri za mankhwalawa. Ngati mukufuna kufunsana kulikonse, mutha kundilumikizana nane nthawi iliyonse ndikuyesetsa kukupatsirani zokhutiritsa kwambiri zogulitsa zisanachitike komanso zogulitsa pambuyo pogulitsa. Mauthenga anga ali pansipa, landirani mafunso anu.

Maoda operekedwa isanakwane 17:00 kuyambira Lolemba mpaka Lachisanu kaŵirikaŵiri adzatumizidwa kuchokera kufakitale kupita kwa wotumiza katundu tsiku lomwelo (kaŵirikaŵiri osati kutumizidwa Loweruka ndi Lamlungu), ndipo adzafika kwa wotumiza katundu mkati mwa masiku atatu kapena anayi.
Wotumiza katundu adzapereka nambala yotsatiridwa yapadziko lonse lapansi patsiku kapena tsiku lotsatira lofika.
Kutengera dziko, tidzagwiritsa ntchito njira zosiyanasiyana zotumizira. Nthawi zambiri, mizere yodzipatulira, katundu ndi ntchito za positi ndizo zikuluzikulu, ndipo zina zimatumiza ku DHL, Fedex, UPS, ndi zina.
