Ubuninzi benani - indlela yokuchaza ngayo?

Ubuninzi bezinto eziphathekayo bubungakanani bobunzima beli qumrhu kwilizwe elitsha elichithwe ngokutsha. Oku kuqwalasela kokubili umthamo wezinto ngokwawo, kunye nomthamo we-voids ngaphakathi kwawo kunye nomthamo phakathi kweengqungquthela zomntu ngamnye (umzekelo, kwilahle.). Ngezizathu ezicacileyo, olu hlobo loxinano luphantsi kobuninzi bokwenene, obungabandakanyi i-voids ekhankanywe ngasentla.

Ukuchonga ubuninzi benani, izixhobo ezinjengezinga, umlawuli, "I-standard standard", isitya esilinganiselweyo somqulu othile sisetyenzisiweyo. Ubuninzi bomthamo obuthile bunqunyanyiselwe umxholo othile ngomxholo othile omswakama. Ukuba isampuli ayinakuhlangabezana neemfuno zobuncitshisi, iyanqunyulwa okanye, ngokuphindaphindiweyo, yomiswe.

Xa sichaza ukuba ubuninzi bomnxeba bunjani , i-algorithm yezenzo kufuneka ibe ngolu hlobo:

1. Isitya sokulinganisa sisilinganisiwe kwaye sifakwe phantsi kwe-funnel ejwayelekile (ine-shutter esuka ngaphantsi).

2. Isanti ithululwa kwi-funnel, emva koko i-bolt ivuliwe ukuze isanti ithole ngokukhawuleza kwisitya sokulinganisa, igcwalise kwaye yenze intaba ukusuka phezulu.

3. Umnxuwa ogqithisiweyo "unqunyulwe" ngumlawuli ngokunyakaza ngaphezulu kwesitya sokulinganisa.

4. Isitya esinesihlabathi sisilinganisiwe, ubunzima besitya ngokwayo sisuswe kwi-mass mass.

5. Ubuninzi bobuninzi bubalwa.

6. Uvavanyo luphindwaphindwa kabini amaxesha amathathu, emva koko ixabiso eliqhelekileyo libalwe.

Ukongeza kokuxininisa kwimeko ephosakeleyo, ubuninzi beenguqu ezihlanganisiweyo zilinganiswa. Ukwenza oku, isanti kwisitya iyahlanganiswa encinane kwisitrato esishukumisayo kwi-0.5-1 imizuzu. Bala ubuninzi bomninzi we-samente, ungenza ngendlela efanayo.

Ngokuhambelana neGOST 10832-2009, isanti yoluthile oluthile (olwandisiweyo) ngobuninzi bobuninzi luhlulwe ngamabakala athile - ukusuka kwi-M75 (i-index index 75 kg / m3) ukuya kwi-M500 (ubuninzi be-400-500 kg / m3). Ukunikezelwa kwinqaku elithile, isanti kufuneka ibe ne-conductivity ethile kunye namandla xa ucima. Ngokomzekelo, ukuqhuba kwe-thermal ye-brand M75 kwiqondo lokushisa kwama-25 C + -5 C akufanele kube ngaphezu kwe-0.043 W / m 3 C. Yaye amandla okhathalela i-M500 isanti ichazwa njenge-0.6 mPa (engekho ngaphantsi). Uhlobo lwe- quartz (umxholo womswakama we-5%) unobuninzi obuninzi be-1500. Ngomsila, eli nani li malunga ne-1200 kg / m3 kwiimeko ezihamba ngokukhululeka kwaye malunga ne-1600 kg / m3 kwimeko yokuzibandakanya. Ngokuqhelekileyo, umlinganiselo wesilinganiso seekhilomitha ezingama-1300 / iikhijithali isetyenzisiwe kubalo.

Kutheni sifuna ubuninzi benani? Inyaniso kukuba ekuthengisweni kwezorhwebo le ntengo isetyenzisiweyo, kungekhona ukunyaniseka okwenyaniso (umzekelo, ukuba isanti idayiswa kwiingxowa). Ngoko ke, ukuze uguqulele amaxabiso ngamithayubhi nganye kwiitoni nganye ngetoni, kufuneka nje ukwazi ukuba yintoni ubuninzi bezinto eziphathekayo. Ukongezelela, kuba ukulungiswa kwemithi yamanzi kungadinga i-bulk okanye idatha yesisindo, kuxhomekeke kwimigaqo.

Yonke ingcaciso malunga nemveliso, kubandakanywa ubuninzi, isetyenziswe kwiphakheji nganye ngokupakisha, ukusebenzisa ipeyinti yepencil okanye ngokushicilela kwilebula. Apha uya kufumana ulwazi malunga nomenzi, umlando, umhla wokuveliswa kunye nenombolo yeetch, inani lempahla kwiphakheji kunye nomqondiso wokuhambelana.
