Macluumaadka Baaritaanka
Baaritaanka bulkshinka test waa habka saxda ah ee lagu qiimeeyo tusaalayaal waaweyn oo kiimyada ah (bulk samples) laga soo qaatay alaabta ganacsi ee aan la duubin sida macdanta, birta, dab dhigista, basasha, sunta beeraha, waxyaabaha kimikada ah ee gadidka ah iyo agabka warshadda, ka hor inta aan la dhoofin ama la isticmaalin warshadda. Baaritaanka bulkshinka test waxaa loo isticmaala beeraha, gaadiidka badda, Warshadaha dhismaha, warshadaha kimikada, iyo ganacsiga caalamiga ah oo ay u baahan yihiin xog daboolan oo ku saabsan tayada, nabadgelyada, iyo waxtarka alaabta qiyaastii dhan.
Ujeeddada baaritaanka bulkshinka test waa in la xaqiijiyo in tusaalaha waa weyn ee alaabta la keeno uu ka kooban yahay waxyaabo la filayo, inuu ka baxsan yahay wasakhda, cufnaanta khatarkeeda, iyo in uu u dhigma qeexitaanka iyo heshiisyada iibsashada. Farsamooyinka la isticmaalo waxaa ka mid ah dheefshidda kiimikada (chemical digestion), kimiko-analaytical analysis sida ICP-OES, ICP-MS, AAS, XRF, titration, gravimetric analysis, chromatography, spectroscopy, iyo bioassays marka ay timaado sunta beeraha iyo alaabta la cuno. Sababtoo ah alaabta bulk ah way kala duwan tahay dhammaan qaybta walaxa, qaybinta tusaalaha (sample splitting) iyo homogenizationku waa qayb muhiim u ah habka si xogtu u noqoto mid matalaya guud ahaan shippinka.
Habka caadiga ah ee baaritaanka bulkshinka test waxa uu bilaabmaa qaybinta tusaalaha adag (mechanical splitting/riffling), enejinta iyo enejinta kululeynta (drying and milling), ka dibna jaraynta qaybaha kala duwan sida cufnaanta bulk density, contentka biyo (moisture), ash content, volatile matter, iyo dulmiyaha curiyeyaasha (elemental composition). Xubnaha muhiimka ah ee la cabbiraa waxaa ka mid ah boholka (porosity), cufnaanta degdegta ah (tap density), cabbirka qaybaha (particle size distribution), iyo heerarka macaadanta sinta ah saska ah.
Waqtiga cusbooneysiinta xogta, nabadgelyada kaalinka, iyo kala duwanmaan adeegga ayaa ka dhigan in baaritaanka bulkshinka test uu noqdo qayb maamulka tayada iyo khatar-ka heshiisyada ganacsiga ee shirkadaha dhoofinta, soo dhoofinta, iyo warshadaha isticmaala alaabta kiimyada ah ee waaweyn.
Qalabka Baaritaanka

Dulmar
Baaritaanka bulkshinka test waxa uu daboolaa qiimeynta tusaalayaasha waaweyn ee macdanta, dhuxusha, cement-ka, sunta beeraha, kimikada, iyo alaabta cuntada, iyadoo la cabbirayo parameters sissa moisture, ash, elemental composition, calorific value, iyo contaminants. Waqtiga adeegga badankooda waa 7 ilaa 15 maalmoo shaqo, kharashkuna waxa lagu go'aamiyaa tiroda baaritaanka la codsado. Waxaa la heli karaa taageero farsamo oo laga bilaabo sampling guidance ilaa qiimeynta saxda ah ee xubnaha kala duwan.
