Ndi angati njerwa mu poto - m'pofunika kudziwa kuti mayendedwe Katundu

Pa ntchito yomanga Boom kuti chinawononga dziko linati chiwerengero wopandamalire. Anatsegula yomanga chofunika zomangira, kumanga zomera latsopano kupanga awo. Wotchuka kwambiri ndi njerwa, amene khalidwe kusintha sayansi ya ntchito mosalekeza.

Origin njerwa

Zikuoneka kuti njerwa yomanga nyumba nthawi zonse ntchito, icho chinali kugwiritsidwa ntchito pomanga mapiramidi, zinadziwika kwa 3-2 zaka BC. Calcined dongo, njerwa kupanga anthu wosazindikira ndi akale kwambiri. Pa zaka, matabwa ake anasintha. Fomu zonse zinali bokosi lili kachulukidwe wa zomangamanga. Only anasintha kutalika, kufika akadakwanitsira ntchito - 25-6-6,5 (monga angathe kudziwa chiwerengero cha njerwa pa mphasa - CD wapadera zoyendera).

Mitundu ndi makulidwe a njerwa

Kwa zaka zambiri mu nyumba miyala ya dongo ndi zidina. Masiku ano, pali njerwa silicate, ceramic ndi hyperpressed. Zikupereka kusiyana amenewa - wofiira, woyera ndi kukongoletsa. Aliyense ali ndi cholinga ndi wosatsutsika yake ubwino - ena ndi chisanu wabwino, ena wabwino phokoso kutchinjiriza. Mitundu ya njerwa ndi zotsatirazi: bala, yuro, mbeta, limodzi ndi theka, muyezo awiri ndi yosalala, pali ovutika imodzi kapena ziwiri nkhope. Onsewo ali ndi magawo awo.

Makulidwe a kumanga mwala osiyana, ngakhale ndekha, koma wotsatira nkhani msewu:

• 25h12h6,5 - deta muyezo umodzi kapena yosalala (osati nthawi yomweyo angati njerwa osakwatira mphasa kwa - 275 zidutswa);
• 25h6h6,5 - bala, ovutika njerwa konsekonse ong'ambika, pansi. Pa avareji iwo mphasa kukula aikidwa zidutswa 375;
• 25h9h6,5 - ovutika njerwa - kuchuluka kwa ndalama 307 pa mphasa ndi.

Kuwerengetsera chofunika zoyendera

Kodi ndikudziwa angati njerwa mu poto? Kwa mawerengedwe zolondola wa mphasa kukula kugawidwa ndi kukula kwa njerwa, ndiye kuchulukitsa ndi wovomerezeka pa mtundu wa mwala chiwerengero cha mizere (salinso - musaime mphasa), ndi kupeza chiwerengero chofunika. deta kuti muli sing'anga-kakulidwe tatchula pamwambapa. Koma njerwa zakhala zikuzunza m'miyoyo pa mphasa m'njira ina, mwinanso - "herringbone", pa makona a madigiri 45, kenako kuchuluka kwa zomangira adzakhala osiyana. Iwo ayenera kutengedwa.

Itanitsani zofunika zakuthupi nyumba zambiri lamanja, kudziŵa njerwa ambiri mu mphasa ndi chidebe unalonga ndi yabwino kwambiri, kasitomala akhoza napitirira.

Miyeso ya njerwa muyenera kudziwa kuphatikizapo zoyendera mosavuta. A nthawi yaitali mulibe pambuyo nkhondo magalimoto aakulu odzaza ndi njerwa popanda ma CD. Safunsa iwo ku malo unsembe "dzanja". Njerwa tsopano chikusuntha muli ndi wapadera - muli, pallets, phukusi. Wotchuka kwambiri phukusi - pallets, amenenso zidzasankhidwa ndi mtundu - ndi ngowe ndi mipiringidzo, kukula - ambiri akuthamangira kwa iwo 520h1030, 600h1915 ndi 520h1740.

mtengo wotsika zoyendera - kuchepetsa mtengo wa chinthu

Pallets (dzina lina la ma CD) anapangidwa wa matabwa, zitsulo ndi matabwa zachitsulo. Zitsulo muli ntchito osati chifukwa kunyamula, komanso kuchotsa kuchokera kilns njerwa. Funso la "momwe njerwa ambiri mu poto" si ulesi. Kuyambira zimatengera kulipira zoyendera - pallets ochepa, malipiro ochepa. Ndipo apa m'pofunika kupereka kwa onse, kuti asapitirire mtengo wa zomangamanga wa chinthu.

Chiwerengero cha njerwa zofunika kumanga nyumba, ndi kuwonjezekeredwa ntchito chitsanzo. Kudziwa chiwerengero cha muli chofunika chingapezeke mwa kugawa chiwerengero cha mtundu uwu zomangila pa chiwerengero chawo mu mphasa lapansi. Yankho la funso njerwa angati pa poto, kuthandiza kuzindikira ndi zoyendera - mmene magalimoto ambiri ndi mphamvu katundu ayenera kugwiritsa ntchito katundu wa.
