Calcium carbonate CAS 471-34-1
Calcium carbonate ufa woyera, wopanda fungo komanso wopanda kukoma. Pafupifupi osasungunuka m'madzi. Zosasungunuka mu mowa. Monga chotupitsa chamankhwala, chitha kugwiritsidwa ntchito muzakudya zosiyanasiyana zomwe zimafunikira kuwonjezeredwa kwa chotupitsa molingana ndi malamulo aku China, ndipo ziyenera kugwiritsidwa ntchito moyenera malinga ndi zosowa zopanga; Amagwiritsidwa ntchito ngati ufa wowonjezera ufa, wokhala ndi mlingo wokwanira 0.03g/kg.

1. Ntchito zachipatala
Zakudya za calcium: zomwe zimagwiritsidwa ntchito popewa ndi kuchiza kuchepa kwa calcium, monga kufooka kwa mafupa, tetany, fupa la dysplasia, rickets, ndi calcium supplementation kwa ana, amayi apakati ndi oyamwitsa, amayi osiya kusamba, ndi okalamba.
Maantacids: amatha kuchepetsa asidi m'mimba, kuchepetsa zizindikiro monga kupweteka kumtunda kwa m'mimba, acid reflux, kutentha kwa mtima, ndi kupweteka kwa m'mimba chifukwa cha asidi wambiri m'mimba, komanso angagwiritsidwe ntchito pochiza matenda monga zilonda zam'mimba ndi duodenal, gastritis, ndi esophagitis.
Zodzaza mankhwala ndi zowonjezera: kupititsa patsogolo kukhazikika ndi bioavailability wa mankhwala.
2. Makampani opanga zakudya
Zowonjezera zakudya: zowonjezeredwa ku mkaka, zakumwa, mankhwala, mabisiketi, makeke ndi zakudya zina kuti zithandize calcium supplementation.
Kusiya wothandizila: chotupitsa wothandizila akamagwira kuwirikiza ndi sodium bicarbonate, alum, etc., pang'onopang'ono kumasula mpweya woipa pamene usavutike mtima, kuti chakudya umabala yunifolomu ndi wosakhwima wodzitukumula thupi, amene akhoza kusintha khalidwe la makeke, mkate, ndi masikono.
Acidity regulators: amagwiritsidwa ntchito kusintha pH ya chakudya.
3. Munda wa mafakitale
Zipangizo zomangira: Ndi imodzi mwazinthu zofunika kwambiri za simenti. Ikhoza kupititsa patsogolo mphamvu zopondereza, mphamvu zosunthika ndi kulimba kwa simenti, kupititsa patsogolo ntchito yomanga simenti, kupititsa patsogolo kayendetsedwe ka zivomezi zanyumba, komanso kungagwiritsidwe ntchito kupanga laimu, pulasitala, ndi zipangizo zopaka pulasitala.
Makampani apulasitiki: Monga zodzaza ndi zosintha, zimatha kukonza kuuma, kukana kuvala, kulimba kwamphamvu, kukana kutentha ndi kukana kwa mapulasitiki, ndikuchepetsa mtengo wopanga. Amagwiritsidwa ntchito kwambiri podzaza ma resin monga polyvinyl chloride (PVC), polyethylene (PE), ndi polypropylene (PP).
Makampani a mphira: Monga chodzaza ndi kulimbikitsa, chitha kuwonjezera kuchuluka kwa mphira, kuchepetsa mtengo wazinthu, kukonza magwiridwe antchito, ndikuwongolera kwambiri kukana kuvala, kung'ambika, kulimba kwamphamvu, modulus, komanso kukana kutupa kwa mphira wovunda.
Makampani opanga mapepala: Monga chojambulira mapepala ndi zokutira pigment, imatha kutsimikizira kulimba ndi kuyera kwa pepala pamtengo wotsika, kuthandizira kukweza ndi kutulutsa mapepala, komanso kugwiritsidwa ntchito popanga mapepala apamwamba kwambiri.
Chitetezo cha chilengedwe: chimagwiritsidwa ntchito ngati adsorbent ndi precipitant kuchotsa zinthu zovulaza m'madzi, kuchepetsa kuuma kwa madzi, kukonza madzi abwino, komanso kugwiritsidwa ntchito pochiza gasi ndi kukonza nthaka.
Minda ina: yomwe imagwiritsidwa ntchito popanga magalasi, zoumba, mbale zama electrode, zida zamano, ndi zina zambiri, komanso zitha kugwiritsidwa ntchito ngati zowonjezera zakudya zopatsa thanzi komanso zodzoladzola kuti khungu liwoneke bwino.
Nthawi zambiri ankanyamula 25kg/ng'oma, komanso akhoza kuchita makonda phukusi.
