Kalisiyumu sulfate hemihydrate CAS 10034-76-1
Kalisiyumu sulfate nayo yitwa gypsumu mbisi, gypsumu mbisi ikomeye, Muriacite, gypsumu ya anhydrous. Ibara ritagira ibara rya orthorhombic (β ubwoko) cyangwa kristu ya monoclinic (α ubwoko). Uburemere bwa molekile bugereranije 136.14. Ubucucike bugereranijwe 2.960. Gushonga ingingo 1193 ℃ (yahinduwe kuva β ubwoko ihinduka α ubwoko), 1450 ℃ (α ubwoko, kandi ibora). Gushonga buhoro mumazi (0,209 kuri 20 ℃), gushonga muri aside, umunyu wa amonium, sodium thiosulfate, sodium chloride yumuti na glycerol. Nubwo amazi yongeyeho, ntishobora kuba calcium sulfate dihydrate. Niba amabuye ya gypsumu asanzwe afite umwuma munsi ya 300 ℃, hashobora kubyara gypsum ya anhydrous ghydum iboneka mumazi irashobora kubyara; niba gypsumu isanzwe yashyutswe hejuru ya 600 ℃, habaho gypsumu ya anhydrous idashonga. Iyo calcium sulfate ya anhydrous cyangwa plaster ya Paris ivanze namazi akwiye, irakomera buhoro buhoro. Ikoreshwa nka retarder, yifata, ikurura ubuhehere, ifu ya polishinge, kuzuza impapuro, desiccant, gaze ya pompe, nubukorikori. Gypsum ikoreshwa nkibikoresho fatizo byo gukora sima, kandi irashobora guhindura igihe cyo gushiraho sima. Ikoreshwa nka coagulant mugukora tofu, kugaburira umusemburo, kugenzura ifu, hamwe na chelating agent. Hariho amabuye y'agaciro ya gypsumu, kandi ibikomoka ku nganda za fosifate birimo calcium sulfate. Umuti wa ammonium sulfate ukora hamwe na calcium ya chloride ya calcium, kandi kuyungurura, gukaraba no kugwa birashobora gutanga umusaruro mwiza.

Gutunganya ibiryo:
Kalisiyumu sulfate irashobora gukoreshwa nkumuti uvura ifu (nkumuti wa benzoyl peroxide), hamwe nogukoresha garama 1.5 kuri kilo; ikoreshwa nka coagulant mugutunganya ibiryo. Ikoreshwa mu gukora tofu, kandi garama zigera kuri 14-20 kuri litiro ya soya yongewe kumata ya soya (urugero rwinshi ruzabyara umururazi). Yongewemo ifu y ingano kuri 0.15% kandi ikoreshwa nkibiryo byumusemburo hamwe nubugenzuzi bwimigati. Yongewemo inyanya n'ibirayi byafashwe nkibikomeza umubiri. Ikoreshwa nkigikomera cyamazi niyongera uburyohe bwo guteka byeri. Irashobora kandi gukoreshwa nk'inyongera y'imirire.
Umusaruro w'inganda:
1. Ikoreshwa nkimbaraga zambere hakiri kare mubintu bifatika, mubisanzwe hamwe na dosiye igera kuri 3%, kugirango uhindure igihe cyo gushiraho hanyuma uvange kandi usya muri sima. Iyo calcium sulfate yongewe kuri beto, igira ingaruka zikomeye zambere.
2. Inganda zikora impapuro: Kalisiyumu sulfate ikoreshwa mu nganda zikora impapuro zo gusimbuza igice cyangwa igice kinini. Kalisiyumu sulfate ifite igipimo kiri munsi ya 50 cyangwa ingana na 50 irashobora gukoreshwa nkuwuzuza urwego rwohejuru rwimpapuro, rushobora kongera umusaruro wimpapuro, kugabanya gukoresha ibiti, no gufasha kurengera ibidukikije no kugabanya umwanda w’amazi.
3. Inganda zikora imiti: Mu nganda zikora imiti, irashobora gukoreshwa nkibikoresho bishimangira. Anhydrous calcium sulfate whiskers irashobora gukoreshwa muguhindura plastike kugirango yongere imbaraga za plastike, irwanya ubushyuhe bwinshi, kandi igabanye ibiciro. Mu gukora plastike nka polyvinyl chloride, polyethylene, propylene, na polystirene, irashobora kuzamura imikorere yibintu bitandukanye byibicuruzwa, kunoza ubwiza, guhagarara neza, kurangiza hejuru, imbaraga zingana, kunama imbaraga, kunama modulus ya elastike nubushyuhe bwo guhindura ubushyuhe, no kugabanya kwambara ibikoresho. Nkuzuza asifalt, irashobora kongera cyane ingingo yoroshye ya asfalt.
Ubuhinzi:
Kalisiyumu sulfate irashobora gukoreshwa nkifumbire mvaruganda kugirango igabanye ubutaka no kunoza imikorere yubutaka.
Ubuvuzi:
Kalisiyumu sulfate ifite uburyo butandukanye mubikorwa bya farumasi. Irashobora gukoreshwa mugutegura ibiyobyabwenge no gutanga ibikoresho bikenewe hamwe nibiyobyabwenge. Mubyongeyeho, calcium sulfate nayo ikoreshwa mugukora ibinini kugirango ibashe gukomera no gukora neza. Muri icyo gihe, byongewe kandi ku menyo yinyo kugirango yongere imiterere nimirimo yinyo yinyo. Izi porogaramu zigaragaza akamaro ka calcium sulfate mu nganda zimiti, zitanga ibintu byingenzi nibicuruzwa byibikoresho bya farumasi.
