Yintoni iCalcium sulfate hemihydrate CAS 10034-76-1 ?

I-calcium sulfate ikwabizwa ngokuba yigypsum ekrwada, igypsum ekrwada elukhuni, iMuriacite, igypsum engenamanzi. Iikristale ze-orthorhombic ezingenambala (uhlobo lwe-β) okanye iikristale ze-monoclinic (uhlobo α). Ubunzima bemolekyuli obunxulumeneyo 136.14. Uxinzelelo olunxulumeneyo 2.960. Indawo yokunyibilikisa i-1193℃ (iguqulwe ukusuka kuhlobo lwe-β ukuya kuhlobo lwe-α), 1450℃ (uhlobo α, kunye nokubola). Inyibilika kancinane emanzini (0.209 ku-20℃), i-soluble kwi-asidi, ityuwa ye-ammonium, i-sodium thiosulfate, isisombululo se-sodium chloride kunye ne-glycerol. Nokuba amanzi ongeziweyo, ayinakuba yi-calcium sulfate dihydrate. Ukuba i-gypsum ore yendalo iphelelwe ngamanzi ngokupheleleyo ngaphantsi kwe-300℃, igypsum enyibilikayo enyibilikayo enyibilikayo emanzini inokuveliswa; ukuba igypsum yendalo ifudunyezwe ukuya kuthi ga kwi-600℃, i-insoluble anhydrous gypsum iyaveliswa. Xa i-anhydrous calcium sulfate okanye udaka lwaseParis luxutywe nomlinganiselo ofanelekileyo wamanzi, luqina kancinane. Isetyenziswe njenge-retarder, i-adhesive, i-absorbent yokufuma, i-polish powder, ukuzaliswa kwephepha, i-gas desiccant, i-plaster bandage, kunye nomsebenzi wezandla. I-Gypsum isetyenziswa njengento ekrwada yokwenza isamente, kwaye inokulungelelanisa ixesha lokubeka isamente. Isetyenziswa njenge-coagulant ekwenzeni i-tofu, i-yeast feed, isilawuli sentlama, kunye ne-agent ye-chelating. Kukho imigodi ye-gypsum yendalo, kwaye i-byproducts yoshishino lwe-phosphate iqukethe i-calcium sulfate. Isisombululo se-ammonium sulfate siphendula kunye nesisombululo se-calcium chloride, kwaye ukuhluzwa, ukuhlamba kunye nemvula kunokuvelisa imveliso ecocekileyo.

Isicelo

Ukulungiswa kokutya:

I-calcium sulfate ingasetyenziswa njenge-arhente yonyango lomgubo (njenge-diluent ye-benzoyl peroxide), kunye nokusetyenziswa okuphezulu kwe-1.5 grams ngekhilogram; isetyenziswa njenge-coagulant ekwenzeni ukutya. Isetyenziselwa ukwenza i-tofu, kwaye malunga ne-14-20 gram nganye ilitha yeembotyi zesoya zongezwa kubisi lwesoya (izixa ezigqithisileyo ziya kuvelisa ubukrakra). Yongezwa kumgubo wengqolowa kwi-0.15% kwaye isetyenziswe njengegwele lokutya kunye nokulawula intlama. Yongezwa kwiitamatato ezinkonkxiweyo kunye neetapile njengento yokuqinisa izicubu. Isetyenziswa njengento yokuqinisa amanzi kunye nencasa yencasa yokwenza ibhiya. Isenokusetyenziswa njengesongezelelo sesondlo.

Imveliso yemizi-mveliso:

1. Umzi-mveliso wokwakha: I-calcium sulfate ingasetyenziselwa kushishino lokwakha izinto zokwakha, izinto zokugquma i-thermal, iingubo, izinto zokuqinisa, njl. I-calcium sulfate whiskers ine-friction elungileyo, ukugcinwa kobushushu, ukugquma ubushushu, ukuthintela umlilo, ukugqunywa kwe-non-conductor kunye nezinye iipropati, kwaye inokubuyisela i-asbestos njengento ephazamisayo, kunye ne-fireproof (i-fireproof). Isetyenziswe njenge-arhente yamandla kwangaphambili kwi-concrete admixtures, ngokubanzi kunye ne-dosage malunga ne-3%, ukulungelelanisa ixesha lokumisela kunye nokuxuba kunye nokugaya ngesamente. Xa i-calcium sulfate yongezwa kwikhonkrithi, inamandla amakhulu okuqala.

2. Ishishini lokwenza iphepha: I-calcium sulfate isetyenziselwa imboni yokwenza iphepha ukuze ithathe indawo okanye ininzi ye-pulp. I-calcium sulfate ene-aspect ratio engaphantsi okanye elingana ne-50 ingasetyenziswa njenge-high-grade filler yephepha, enokunyusa kakhulu ukuveliswa kwephepha, ukunciphisa ukusetyenziswa kweenkuni, kunye nokunceda ukukhusela indalo kunye nokunciphisa ukungcoliswa kwamanzi amdaka.

3. Ishishini lemichiza: Kwishishini lemichiza, linokusetyenziswa njengento yokuqinisa. Amabhovu e-anhydrous calcium sulfate anokusetyenziswa kwigranulation yeplastiki ukomeleza amandla amasuntswana eplastiki, ukumelana nobushushu obuphezulu, kunye nokunciphisa iindleko. Kwimveliso yeeplastiki ezifana ne-polyvinyl chloride, i-polyethylene, i-propylene, kunye ne-polystyrene, inokuphucula ukusebenza kweenkalo ezahlukeneyo zemveliso, iphucule ukucoleka, ukuzinza komdanso, ukugqiba umphezulu, amandla aqinile, ukugoba imodyuli egobileyo kunye nobushushu bokutshintsha kwe-thermal, kunye nokunciphisa ukunxiba kwezixhobo. Njenge-asphalt filler, inokunyusa kakhulu indawo yokuthambisa ye-asphalt.

Ezolimo:

Icalcium sulfate ingasetyenziswa njengesichumiso kwezolimo ukunciphisa ialkalinity yomhlaba nokuphucula ukusebenza komhlaba.

Iyeza:

I-calcium sulfate ineendlela ezahlukeneyo zokusetyenziswa kwishishini lamachiza. Ingasetyenziselwa ukulungiselela iziyobisi kunye nokubonelela ngezithako ezifunekayo kunye neempawu zeziyobisi. Ukongeza, i-calcium sulfate isetyenziselwa ukwenza iipilisi ukuqinisekisa ukuzinza kunye nokusebenza kakuhle kwamacwecwe. Ngelo xesha, iphinda yongezwa kwi-toothpaste ukunyusa ukubunjwa kunye nomsebenzi we-toothpaste. Ezi zicelo zibonisa ukubaluleka kwe-calcium sulfate kwishishini lamachiza, ukubonelela ngezithako eziphambili kunye neempawu kwiimveliso zamachiza.
