P-Phenylenediamine (Chingerezi p-Phenylenediamine), yomwe imadziwikanso kuti Ursi D, ndi imodzi mwamadiamine osavuta onunkhira. Chovala choyera ndi choyera mpaka kristalo wa lavender, womwe umasanduka wofiirira kapena woderapo ukakhala pamlengalenga. Kusungunuka pang'ono m'madzi ozizira, kusungunuka mu ethanol, ether, chloroform ndi benzene. Itha kugwiritsidwa ntchito popanga utoto wa azo, ma polima apamwamba kwambiri, ndipo itha kugwiritsidwanso ntchito kupanga utoto waubweya, ma antioxidants amphira ndi opanga zithunzi Chemicalbook. Amagwiritsidwa ntchito makamaka ngati utoto wa aramid, azo, utoto wa sulfure, utoto wa asidi, komanso ungagwiritsidwe ntchito ngati ubweya. Kupanga kwakuda D, ubweya wakuda wakuda DB, ubweya wakuda N2, ndi mphira wa antioxidants DNP, DOP, ndi MB. Amagwiritsidwanso ntchito ngati zopangira zodzikongoletsera tsitsi la Ursi D mndandanda, petulo polymerization inhibitor ndi wopanga. Monga utoto wamankhwala, p-phenylenediamine panopa amaloledwa kugwiritsidwa ntchito popanga utoto wa tsitsi, koma pali zoletsa zomveka pa kuchuluka kwa ntchito.
Katundu
Makristalo oyera mpaka lavender. Amakhala wofiirira kapena woderapo akakumana ndi mpweya. Amasungunuka m'madzi, ethanol, ether, chloroform ndi benzene. Ndiwofunika utoto wapakatikati ndipo umagwiritsidwa ntchito makamaka popanga utoto wa azo ndi utoto wa sulfure. Itha kugwiritsidwanso ntchito kupanga ubweya wakuda D ndi rabara antioxidant DNP. Amagwiritsidwa ntchito ngati chizindikiritso cha fulorosenti, chowunikira chowunikira ndi utoto waubweya, komanso chimagwiritsidwa ntchito popanga utoto.

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.
