IsiXhobo soMda woMda weManuwali

Isixhobo sokukhawulelana nolwelo olusetyenziswa ngesandla (iCasagrande) sisetyenziselwa ukumisela isiqulatho sokufuma apho umhlaba wodongwe udlula khona ukusuka kwiplastiki ukuya kwimeko yolwelo.Izixhobo ziquka ikranki ehlengahlengiswayo kunye nekhamera, isibali sokuvuthela kunye nekomityi yobhedu esuswayo efakelwe kwisiseko.

Imitha yomlinganiselo wolwelo wodidi lwesitya isetyenziselwa ukulinganisa umda wolwelo lomhlaba.Sisixhobo esisetyenziselwa ukuyila kunye nokwakhiwa ukuze kuhlelwe iindidi zomhlaba, ukubala ukuhambelana kwendalo kunye nesalathiso seplastiki.

Inkqubo yovavanyo

1. Beka isampuli yomhlaba kwisitya esiphuphumayo, yongeza i-15 ukuya kwi-20 ml yamanzi adibeneyo, uvuselele ngokuphindaphindiweyo kwaye uxoke ngemela yokulungisa umhlaba de uxutywe kakuhle, uze udibanise i-1 ukuya kwi-3 ml yamanzi ngexesha ngalinye, kwaye udibanise kakuhle. ngokwendlela engentla.zonke.

2. Xa umhlaba uxutywe ngamanzi aneleyo ukuze ufikelele kwi-consistency, ulingana nokufuna ukulahla amaxesha angama-30 ukuya kuma-35 ukudibanisa.Beka inxalenye yodaka lodongwe kwisitya esingentla apho isitya sithinta i-plate ephantsi.Sebenzisa imela yokulungisa umhlaba ukucofa incama yomhlaba ibe yimo ethile, nikela ingqalelo ekuwucinezele kaninzi kangangoko, kwaye uthintele amadyungudyungu ukuba angaxutywa kwintlama yomhlaba.Sebenzisa imela yokulungisa umhlaba ukugudisa umphezulu wentlama yomhlaba, kwaye eyona ndawo ijiyileyo yomhlaba intlama yi-1 cm ubukhulu.Umhlaba ogqithisiweyo ubuyiselwa kwisitya esiphuphumayo, kwaye intlama yomhlaba kwisitya inqunyulwe kunye nobubanzi kunye ne-groover evela kumlandeli wecam.I-slot echazwe kakuhle, echazwe kakuhle yenziwe.Ukuze kuthintelwe edge groove ukukrazula okanye intlama umhlaba ukutyibilika esityeni, ubuncinane imivumbo emithandathu ukusuka ngaphambili ukuya ngasemva kwaye ukusuka ngasemva ukuya ngaphambili zivumelekile ukuba endaweni groove omnye, kwaye istrowuke ngalinye ngokuthe ngcembe nzulu de kube lixesha lokugqibela.Ukudibanisa okubalulekileyo kunye nezantsi kwesitya kufuneka kufakwe amanqaku ngamaxesha ambalwa kunokwenzeka.

3. Jika isiphatho se-crank F ngesantya se-2 revolutions ngomzuzwana ukwenza ipleyiti yomhlaba iphakame kwaye siwe de iziqingatha ezibini zomhlaba intlama zichukumise ezantsi kwe-intshi malunga ne-1/2 intshi (12.7 mm).Rekhoda inani lokubetha okufunekayo kubude obuyi-1/2 ye-intshi yoqhagamshelwano olusezantsi lwegroove.

4. Sika isiqwenga somhlaba nge-slot ukusuka kwicala lomhlaba ukuya kwicala, ububanzi balo buphantse bulingane nobubanzi bomhlaba wokusika imela, kubandakanywa nomhlaba kwindawo evaliweyo, uyibeke kwibhokisi yokulinganisa efanelekileyo; yilinganise kwaye uyidibanise.Rekhoda.Bhaka kubunzima obuqhubekayo kwi-230 ° ± 9 ° F (110 ° ± 5 °).Ngokukhawuleza emva kokupholisa kwaye ngaphambi kokumunca emanzini adsorbed, linganisa.Rekhoda ukwehla kobunzima emva kokumisa njengobunzima bamanzi.

5. Hambisa izinto zomhlaba eziseleyo kwisitya kwisitya esiphuphumayo.Geza kwaye womise isitya kunye ne-groover, kwaye uphinde ulayishe isitya sovavanyo olulandelayo.

6. Sebenzisa imathiriyeli yomhlaba ehanjiswe kwisitya esiba ngumphunga ukongeza amanzi ukwandisa ukumanzi komhlaba, kwaye wenze imifuniselo emibini ubuncinane ngokwendlela engentla.Injongo kukufumana iisampulu zomhlaba ezihambelanayo ezahlukeneyo, kunye nenani lamathontsi afunekayo ukwenza izihlanganisi zentlama yomhlaba zihambe kunye ngaphezulu okanye ngaphantsi kwamaxesha angama-25.Inani lamaconsi afunyenweyo kufuneka libe phakathi kwamaxesha angama-15 kunye nama-35, kwaye isampuli yomhlaba isoloko iqhutyelwa kwimeko eyomileyo ukuya kwindawo emanzi kuvavanyo.

7. Ukubala

a Bala isiqulatho samanzi WN womhlaba, esichazwa njengepesenti yobunzima bomhlaba owomileyo;

WN=(ubunzima bamanzi×ubunzima bomhlaba owomileyo)×100

8. Zoba igophe leplastiki

Yila 'igophe lokuhamba ngeplastiki' kwiphepha le-semi-logarithmic;imele ubudlelwane phakathi komxholo wamanzi kunye nenani lokuhla kwesitya.Thatha umxholo wamanzi njenge-abscissa kwaye usebenzise isikali semathematika, kwaye usebenzise inani lokuwa njengolungelelaniso kwaye usebenzise isikali se-logarithmic.Igophe lokuhamba ngeplastiki ngumgca othe tye, omele udlule kwiindawo ezintathu okanye ngaphezulu zokuvavanya kangangoko kunokwenzeka.

9. Umda wolwelo

Kwijika lokuhamba, umthamo wamanzi kumaconsi angama-25 athathwe njengomda wolwelo lomhlaba, kwaye ixabiso lijikelezwe kwinani elipheleleyo.
