Qalabka shaandhada dhulka ee diatomaceous waxay leeyihiin qaab-dhismeed wanaagsan oo daloolo yar yar ah, waxqabadka nuugista, iyo iska caabinta cadaadiska, taas oo aan kaliya u oggolaanayn dareeraha la sifeeyay inuu gaaro saamiga heerka socodka wanaagsan, laakiin sidoo kale wuxuu sifeeyaa adkaha khafiifka ah ee laalaada, taasoo hubinaysa cadad. Dhulka diatomaceous waa dhoobo ka mid ah haraaga hal-unug ee qadiimiga ah ee diatom. Astaamaha ay ka mid yihiin khafiifka, daloolada leh, xoogga sare leh, u adkaysta xirashada, dahaarka, dahaarka, nuugista, iyo buuxinta, iyo sifooyin kale oo aad u fiican.

Dhulka diatomaceous waa dhoobo ka mid ah haraadiga diatom-ka hal unug ee hore. Astaamaha uu leeyahay waxaa ka mid ah khafiif, daloolo leh, xoog badan, u adkaysta xirashada, dahaarka, dahaarka, nuugista, iyo buuxinta, iyo sifooyin kale oo aad u fiican. Waxay leedahay xasillooni kiimiko oo wanaagsan. Waa walax warshadeed oo muhiim u ah dahaarka, shiididda, shaandhaynta, nuugista, ka hortagga xinjirowga, burburinta, buuxinta, iyo side. Waxaa si weyn loogu isticmaali karaa warshadaha sida birta, injineernimada kiimikada, korontada, beeraha, bacriminta, agabka dhismaha iyo alaabada dahaarka. Waxa kale oo loo isticmaali karaa buuxinta shaqada warshadaha ee balaastikada, caagga, dhoobada, sameynta waraaqaha, iyo warshadaha kale.

Qalabka shaandhada dhulka ee diatomaceous waxaa loo qaybiyaa badeecooyin qalalan, badeecooyin calcined ah, iyo badeecooyin calcined ah oo flux ah iyadoo loo eegayo hababka wax soo saarka ee kala duwan.
① Alaabada la qalajiyey
Ciidda ceeriin ee la silica ee la nadiifiyey, hore loo qalajiyey, lana burburiyey waxaa lagu qalajiyaa heerkul ah 600-800 ° C ka dibna waa la burburiyaa. Badeecadani waxay leedahay cabbir aad u fiican waxayna ku habboon tahay shaandhaynta saxda ah. Badanaa waxaa loo isticmaalaa iyadoo lala kaashanayo qalabka kale ee shaandhada. Badeecada la qalajiyey inta badan waa huruud khafiif ah, laakiin sidoo kale waxay leedahay caddaan iyo cawl khafiif ah.

② Badeecada la kariyey
Walxaha ceeriin ee la nadiifiyey, la qalajiyey, lana burburiyey ee dhulka diatomaceous ah ayaa lagu shubaa foorno wareeg ah, oo lagu shubaa heerkul ah 800-1200 ° C, ka dibna la burburiyaa oo la kala saaraa si loo helo badeecada calcined. Marka la barbardhigo alaabada qalalan, marin u helidda alaabada calcined waa in ka badan saddex jeer ka badan. Badeecadaha calcined inta badan waa casaan khafiif ah.

③ Badeecooyinka lagu dahaadhay dareeraha
Ka dib marka la nadiifiyo, la qalajiyo, lana burburiyo, walxaha ceeriin ee dhulka diatomaceous waxaa lagu daraa xaddi yar oo walxo dareere ah sida sodium carbonate iyo sodium chloride, waxaana lagu daraa heerkul ah 900-1200 ° C. Ka dib marka la burburiyo oo la kala saaro cabbirka walxaha, badeecada calcined flux ayaa la helaa. Awooda soo saarista alaabada calcined flux ayaa si weyn u korodhay, taasoo ka badan 20 jeer ka badan alaabada qalalan. Badeecadaha calcined ee flux badanaa waa caddaan, marka maadada Fe2O3 ay sarreyso ama qiyaasta flux ay hooseyso, waxay u muuqdaan casaan khafiif ah.

Cilladaha ugu waaweyn ee qalabka shaandhaynta dhulka ee diatomaceous waa:

1. La'aanta kheyraadka. Soo saarista qalabka shaandhada dhulka ee diatomaceous waxay u baahan tahay dhul tayo sare leh oo diatomaceous ah oo leh diatomaceous badan. Inkasta oo Shiinuhu leeyahay kheyraad badan oo diatomaceous ah, badankood waa miinooyin dhulka ah oo heer dhexdhexaad ah ilaa heer hoose ah, kuwaas oo ay adag tahay in la daboolo shuruudaha wax soo saarka;

2. Qiimaha wax soo saarku waa mid aad u sarreeya. Habka wax soo saarka ee dhulka diatomaceous waa mid aad u adag, oo ay weheliso qiimaha sare ee kheyraadka dhulka diatomaceous tayo sare leh, qiimaha wax soo saarka ee qalabka shaandhaynta dhulka diatomaceous ee Shiinaha ayaa la ilaaliyay heer sare;

3. Heerka sifeynta waa mid gaabis ah cufnaanta guudna waa mid sareysa. Ku darista wax badan iyadoo loo eegayo tayadeeda badanaa ma buuxiso shuruudaha la filayo, ku darista wax badanna waxay kordhin doontaa kharashka. Dadka qaar ayaa doonaya inay horumariyaan alaabada nooca dhulka diatomaceous oo leh cufnaan yar, laakiin sababo la xiriira xaddidaadaha ku jira halabuurka iyo qaab-dhismeedka walxaha ceeriin, natiijooyin qancin leh ilaa hadda lama gaarin;

4. Xasiloonida kiimikada ma aha mid ku habboon. Waxyaabaha ku jira qaybaha waxyeelada leh sida birta iyo kalsiyum ee dhulka diatomaceous waa kuwo aad u sarreeya waxayna ku jiraan xaalad gooni ah, sidaa darteed heerka kala diristiisu waa mid sarreeya. Marka la sifeynayo cabitaanno badan iyo cabitaanno khamri ah, kala diris bir ah oo badan waxay saameyn kartaa dhadhanka iyo dhadhanka badeecada.
