Yintoni iCalcium sulfate hemihydrate CAS 10034-76-1?

I-calcium sulfate ikwabizwa ngokuba yi-raw gypsum, i-hard raw gypsum, i-Muriacite, i-anhydrous gypsum. Iikristale ze-orthorhombic ezingenambala (uhlobo lwe-β) okanye iikristale ze-monoclinic (uhlobo lwe-α). Ubunzima be-molecular obuhambelanayo yi-136.14. Uxinano oluhambelanayo yi-2.960. Iqondo lokunyibilika yi-1193℃ (liguqulwe ukusuka kuhlobo lwe-β ukuya kuhlobo lwe-α), yi-1450℃ (uhlobo lwe-α, kwaye libolile). Linyibilika kancinci emanzini (0.209 kwi-20℃), linyibilika kwi-asidi, ityuwa ye-ammonium, i-sodium thiosulfate, isisombululo se-sodium chloride kunye ne-glycerol. Nokuba amanzi ongeziweyo, akanakuba yi-calcium sulfate dihydrate. Ukuba i-gypsum ore yendalo iphelelwe ngamanzi ngokupheleleyo ngaphantsi kwe-300℃, i-soluble anhydrous gypsum enyibilikayo emanzini inokwenziwa; ukuba i-gypsum yendalo ishushu ngaphezulu kwe-600℃, i-inhydrous gypsum enganyibilikiyo iyaveliswa. Xa i-anhydrous calcium sulfate okanye i-plaster yaseParis ixutywe nomlinganiselo ofanelekileyo wamanzi, iyaqina kancinci. Isetyenziswa njenge-retarder, i-adhesive, i-moving massive, i-polish powder, i-paper filling, i-gas desiccant, i-plaster bandage, kunye ne-handicraft. I-Gypsum isetyenziswa njenge-raw material yokwenza isamente, kwaye inokulungisa ixesha lokuseta isamente. Isetyenziswa njenge-coagulant ekwenzeni i-tofu, i-yeast feed, i-dough regulator, kunye ne-chelating agent. Kukho imigodi ye-gypsum yendalo, kwaye iimveliso eziphuma kwishishini le-phosphate ziqulethe i-calcium sulfate. Isisombululo se-ammonium sulfate sidibana nesisombululo se-calcium chloride, kwaye ukuhluza, ukuhlamba kunye nokuna kwemvula kunokuvelisa imveliso ecocekileyo.

Isicelo

Ukulungiswa kokutya:

I-calcium sulfate ingasetyenziswa njengesixhobo sonyango lomgubo (njengesinyibilikisi se-benzoyl peroxide), kwaye ukusetyenziswa kwayo kuphezulu yi-1.5 grams ngekhilogram; isetyenziswa njenge-coagulant ekulungisweni kokutya. Isetyenziselwa ukwenza i-tofu, kwaye malunga ne-14-20 grams ngelitha yesoya zongezwa kubisi lwesoya (ubuninzi bayo buya kubangela ubukrakra). Yongezwa kumgubo wengqolowa kwi-0.15% kwaye isetyenziswe njengomlawuli wokutya kwemvubelo kunye nentlama. Yongezwa kwiitamatisi ezisemathinini kunye neetapile njengesiqinisi sezicubu. Isetyenziswa njengesiqinisi samanzi kunye nesiphuculisi sencasa yokwenza ibhiya. Ingasetyenziswa njengesongezelelo sesondlo.

Imveliso yemizi-mveliso:

1. Ishishini lokwakha: I-calcium sulfate ingasetyenziswa kwishishini lokwakha kwizixhobo zokwakha, izixhobo zokukhusela ubushushu, ii-coating, izixhobo zokuqinisa, njl. Iindevu ze-calcium sulfate zinoburharha obuhle, zigcina ubushushu, zikhusela ubushushu, zithintela umlilo, zikhusela ubushushu obungengomqhubi wekhontrakthi kunye nezinye iimpawu, kwaye zinokuthatha indawo ye-asbestos njengezinto zokukhusela ubushushu, izinto zokukhusela ubushushu, kunye nezinto ezingatshiyo (ezithintela umlilo). Isetyenziswa njengesixhobo samandla okuqala kwi-concrete admixtures, ngokubanzi ine-dosage emalunga ne-3%, ukulungisa ixesha lokuseta kunye nokuxuba kunye nokusila kwisamente. Xa i-calcium sulfate yongezwa kwikhonkrithi, inefuthe elibalulekileyo lamandla okuqala.

2. Ishishini lokwenza amaphepha: I-calcium sulfate isetyenziswa kwishishini lokwenza amaphepha ukuze ithathe indawo yenxalenye okanye uninzi lwepulp. I-calcium sulfate enomlinganiselo wobungakanani obungaphantsi okanye obulingana nama-50 ingasetyenziswa njengesizalisi sephepha esikumgangatho ophezulu, esinokunyusa kakhulu imveliso yephepha, sinciphise ukusetyenziswa kwemithi, kwaye sincede ekukhuseleni okusingqongileyo kwaye sinciphise ungcoliseko lwamanzi amdaka.

3. Ishishini leekhemikhali: Kwishishini leekhemikhali, ingasetyenziswa njengezinto zokuqinisa. Iiwhiskers ze-calcium sulfate ezingenanto zingasetyenziswa kwi-granulation yeplastiki ukomeleza amandla eenxalenye zeplastiki, ukumelana nobushushu obuphezulu, kunye nokunciphisa iindleko. Kwimveliso yeeplastiki ezifana ne-polyvinyl chloride, i-polyethylene, i-propylene, kunye ne-polystyrene, inokuphucula ukusebenza kweempawu ezahlukeneyo zemveliso, iphucule ubunono, uzinzo olulinganayo, ukugqitywa komphezulu, amandla okutsalwa, amandla okugoba, i-modulus ye-elastic egobayo kunye nobushushu bokuguqulwa kobushushu, kwaye inciphise ukuguguleka kwezixhobo. Njenge-asphalt filler, inokunyusa kakhulu indawo yokuthambisa ye-asphalt.
