I-QMR2-40 ithengiswe ngekhwalithi ephezulu umtjhini wokwenza isitina sobumba

Umtjhini we-QMR2-40 we-Clay wokwenza iintina ngomunye umhlobo omutjha womtjhini wokwenza amabhlogo amancani, otjhiphileko begodu ohlala isikhathi eside, kulula ukuwusebenzisa begodu ongenamandla. Ikhawuleza ekwakheni umkhiqizo, iphezulu ngokuminyana komkhiqizo begodu inamandla wokucindezela. Ngemva kokubumba kabutjha abantu bangama phezu kwesitini. Ngomtjhini lo, ukusetjenziswa kwezinto kungehliswa. Yikhetho elihle khulu lekhasimende. Umtjhini lo mhlobo omutjha womtjhini wokwenza iintina owenziwe ngokuya ngokufunwa okukhulu kwemakethe e-Afrika. Nayiqathaniswa neminye imitjhini, ubuhle bayo obukhulu khulu yisakhiwo sayo esilula, ukusebenza lula, kanye neendleko eziphasi, okwenza bona ibe yikhetho elihle labatjalimali abancani nabaphakathi eendaweni ezingakathuthuki.

Imininingwana yomkhiqizo

Imininingwana yomkhiqizo isigaba sokuqukethwe kwekhasi:

Ihlathululo yomkhiqizo

I-QMR2-40 mtjhini wokwenza izitina ngezandla, ungakhiqiza umtjhini wokwenza izitina zokuphepha kanye nokwenza izitina ezihlanganisako. Umtjhini lo usebenza ngesandla, begodu umtjhini owodwa usebenzisa umfutho we-8MPa ukufaka umfutho eentweni ezingakasetjenzwa esikhunjeni, ngaleyo ndlela kwakhiwa izitina, okuyinto engalimazi ibhoduluko. Umtjhini lo ungakhiqiza amajamo wezitina wezakhiwo ezihlukahlukeneko ngokutjhugulula isikhunta. Iintina ezikhiqizako zingahlanganiswa begodu zifakwe ndawonye emgqeni oqondileko nofana emigqeni emibili enamagagasi, begodu ingaphezulu leboda livalwe khulu, ngaphandle kwesidingo sokuvala izikhala ngedaka, okungasiza ukuvimba ukutjhisa.

Ukucaciswa

Umtjhini lo wenza iintina ezimbili nofana ngaphezulu zobumba qobe ngemva kwemizuzwana ema-40 begodu ungakhiqiza iintina ezifika ku-1440 ngelanga. Umtjhini lo awutlhogi ukusetjenziswa kwegezi, kutlhogeka ukukhiqiza ngezandla kwaphela. Ubukhulu boke bomtjhini lo buyi-600 * 700 * 1200mm, begodu ukuhlukaniswa nokupakisha kuyisikwere semitha yinye. Iinsetjenziswa eziqakathekileko zokwenza umtjhini lo yi-gypsum cement yehlabathi yodaka.

Ubuhle

Iinkhunta zomtjhini wethu zenziwa kusetjenziswa amathulusi aphezulu, okuqinisekisa bona ukunemba kwephutha lobukhulu besitina kulawulwa ngaphakathi kwamamilimitha ayi-0.1. Iintina ezikhiqizako zinemiphetho ekhanyako, imigqa ebushelelezi, kanye namajamo amahle. Izakhiwo ezenziwe ngezitina lezi zizokuba nomphumela obonakalako wemikhakha emithathu, imikhiqizo yesiko engekhe ifane nayo. Ngaphezu kwalokho, umtjhini lo uyakwazi ukukhiqiza izitina ezinamaketango ezinezakhiwo ezihlukileko, Ngaphezu kwalokho, udonga olwenziwe ngezitina lubukhali khulu, ngaphandle kwesidingo sokuvala izikhala, begodu lungasebenza njengesivikelo. Ifemu yethu inomlando wokukhiqiza weminyaka ematjhumi amathathu begodu sele ithumele emazweni angaphezu kwe-150. Sinamagatja amanengi namafemu e-Afrika, begodu sinelwazi elinengi lokukhiqiza. Umkhiqizo lo unomklamo omutjha, ubukhulu obuncani, begodu ulungele ukutjala imali okuncani. Ingakghona ukukhiqiza iintina ezisezingeni eliphezulu.
