Yazvino mamiriro eGypsum block

Achievement-1-6Mune ma1940s, semi-hydrated gypsum yakaitwa kubva kune yakasikwa gypsum yakashandiswa pasirese kugadzira gypsum mabhuroko nenzira yakapfava yekukanda nzira. Pakati-ma1950, kugadzirwa kwacho kwakachinjiswa kuve yakatwasuka muforoma kukanda uye jacking tekinoroji, uye goho rakawedzera zvakanyanya.

Kubvira kuma1970, iyo yekugadzira tekinoroji yakaenderera ichivandudzwa, uye iyo yakatwasuka muforoma yekusimudza maitiro yakagadziriswa kubva kune semi-otomatiki kusvika zvizere otomatiki. Semuenzaniso, kushandisa hydraulic otomatiki vanocheka kugadzira kumusoro grooves, alloy mafuru akavezwa chrome-kuifukidza kunatsiridza chigadzirwa chemhando yepamusoro, akawanda-mhango mafuru anoshandiswa kuwedzera imwechete michina kuburitsa, uye pneumatic telescopic zvisungo zvinoshandiswa kunyatsoisa nzvimbo, kiramba, kusimudza uye fambisa mutsara wese wemabhuroko.

Kubva kuma1990, flue gasi desulfurization gypsum yakashandiswa senge mbishi yekutsiva gypsum yechisikigo, uye mhando yezvigadzirwa zvave zvichiramba zvichivandudzwa.

Gypsum mabhuroko anogadzirwa uye anoshandiswa mune dzinopfuura makumi matanhatu nyika kutenderera pasirese, ayo anonyanya kushandiswa seasina-kutakura-anotakura emukati ekuparadzanisa madziro munzvimbo dzekugara, zvivakwa zvehofisi, mahotera, nezvimwe.

Izvo zvave zvichizivikanwa pasi rose kuti gypsum block ndeye yakasarudzika girini yekuvaka zvinhu chigadzirwa, kuverenga pamusoro peanopfuura makumi matatu muzana ehuwandu hwakazara wemadziro emukati muEurope. Nyika dzeEuropean dzinogadzira nekushandisa gypsum block dzinosanganisira Russia, France, Germany, Belgium, neSpain, Poland, Italy, Austria, Switzerland, Luxembourg, Greece, Turkey, Finland, Czech Republic, Romania, Bulgaria, Serbia, nezvimwe.

Pamusoro pe mainland China, kune nyika gumi neshanu nematunhu muAsia anogadzira gypsum mabhuroko, aine huwandu hunosvika zviuru zviviri zvemasayiti ekugadzira. Iyo huru Asia gypsum block inogadzira nyika nematunhu ndeaya: India, South Korea, Singapore, Thailand, Indonesia, Pakistan, Afghanistan, Vietnam, Bangladesh, nezvimwe; Middle East inosanganisira Iran, Saudi Arabia, Israel, Jordan, Lebanon, Syria, Oman, Iraq, nezvimwewo Nyika dze Africa gypsum block inogadzira nyika iAlgeria (2 miriyoni square metres / a), Egypt, Morocco, Tunisia, Senegal, nezvimwe.

Mexico chete ndiyo inogadzira gypsum mabhuroko muNorth America. Vagadziri veSouth America gypsum block iBrazil, Chile, Argentina, Venezuela, neColombia. Australia chete ndiyo inogadzira gypsum mabhuroko muOceania.
