Kodi kukonza ndalama

Njira kuyeretsa zimatengera pa zitsulo za ndalama. Chinthu chovuta mu zotsatira m'nyumba maonekedwe yachibadwa ndalama mkuwa, mkuwa, mkuwa. Chifukwa kukhudzana ndi mpweya, iwo ataphimbidwa ndi ❖ kuyanika mdima. Zimakhala wakuda, wobiriwira kapena buluu (nthawi zina kolakwika kwa nkhungu). Chinthu ndi mu mlengalenga pali madzi nthunzi, mpweya woipa ndi sulfide wa hydrogen. Malinga mipweya, amene ankagwira ntchito pa ndalama, ndi mtundu anatsimikiza ndi zolengeza.

• Red mtundu ndi chitumbuwa zolengeza popangidwa ndi okusayidi mkuwa. Tayani izo, akusunsa mankhwala mu 5-15% njira ammonia. Nkofunika kwathunthu kumiza ndalama mu njira, kuyambira zotsatira zina mpweya kungasokoneze pa zitsulo. Mu mkuwa ndi siliva ndalama akhoza kugwiritsidwa ntchito 5-10% ammonium carbonate njira.
• Pamene chikasu mtundu wa zolengeza ntchito asidi acetic. Choncho, ngati 10%.
• Chophweka njira kuyeretsa pa ❖ kuyanika yochitidwa. Chakwanira kusiya ndalama kwa masiku angapo mu madzi otchezedwa kenako kuyeretsa mankhwala ndi burashi zofewa.
• Ndi wakuda kukhudza kwambiri. Poyamba, pamwamba ayenera lilipoli ndi swab ankawaviika amoniya, pambuyo rinsing ndalama madzi otentha sopo. Njira ina ndi ntchito mayeso a viniga. Kusakaniza ndi amsupuni ka ufa ndi yofanana viniga ndi osakaniza chifukwa yomweyo kabati ndalama. Pambuyo atayanika padziko mayeso ikhoza kuchapidwa ndi nsalu zofewa kapena burashi.
• Kukonza ndalama, monga malata, wosiyana ndi ena. Mukhoza kugwiritsa ntchito mafuta Frying. mafuta ndi bwino kugwiritsa ntchito Vaselini, koma saizi ndi masamba. Ziyenera adzanyamula kukumbukira kuti kuwira mfundo ya mafuta kwambiri kuposa madzi.

Kukonza ndalama siliva ali ndi makhalidwe yake. Chifukwa n'zotheka ntchito wamba soda. Lifunika kusungunuka mu pang'ono madzi ndi slurry chifukwa kuyeretsa pamwamba. The njira yomweyo angagwiritsidwe ntchito kupereka kuwala. Ngati ntchito kumaphatikizapo kuchotsa ndalama zobiriwira zolengeza, ndi bwino ntchito sulfuric asidi njira. Lifunika anazitsanulira mwa chikho zadothi, kusiya ndalama mu izo. Patapita nthawi kuti icho, burashi ndi kuviika mu chidulo kachiwiri. Bwerezani stepi ino n'kofunika kupeza chifukwa zogwira mtima.

Njira zamakono - ndi kukonza electrolysis ndalama. Ntchito makina Tisaiwale za chitetezo. Ndalama kuyeretsa ndondomeko kutenga mphindi zingapo, onse amadalira makulidwe a matope. Makamaka ndalama zovuta malo ayenera kutsukidwa ndi mpeni.

ndalama Shoe zikhoza kupangidwa ndi ndodo. Ali reagents zina zosiyana ndi iwo akhoza kupulumutsa bukuli ndi chitetezo. Ambiri oyamba umbuli amawononga ndalama pamene inu muyesera kuyeretsa nokha. Kotero ngati inu muli Ndi chipeneko pa chiyambi cha anapeza, ndi bwino kupereka akatswiri kuyeretsa. Kotero inu kupulumutsa bukuli. Ngati ina kusankha kugulitsa ndalama, maonekedwe ake adzakhala chinthu akuganizira mwa mapangidwe mitengo.
