Sodium fluoride,imhando yemusanganiswa wezvinhu zvisingasanganisike, fomura yemakemikari ndeye NaF, inonyanya kushandiswa muindasitiri yekuputira semushonga wekumhanyisa phosphate, mushonga wezvipembenene wekurima, zvinhu zvekuvharira, zvinochengetedza nezvimwe.
Zvimiro zvemuviri:Kuwanda kwemvura i2.558 (41/4 ° C), kunyunguduka kwemvura i993 ° C, uye kufashaira kwemvura i1695 ° C [1]. (Kuwanda kwemvura 2.79, kunyunguduka kwemvura 992 ° C, kufashaira kwemvura 1704 ° C [3]) Inonyunguduka mumvura (15 ° C, 4.0g/100g; 25 ° C, 4.3g/100g chemicalbook), inonyunguduka muhydrofluoric acid, uye hainyunguduke muethanol. Mhinduro yemvura ialkaline (pH = 7.4). Ine chepfu (inokuvadza tsinga dzemuviri), LD50180mg/kg (mbeva, dzinonwiwa nemuromo), 5-10 magiramu kusvika pakufa. Hunhu: upfu hwecrystalline husina ruvara kana kuti hwakachena, kana makristaro ecubic, makristaro akapfava, asina hwema.
Hunhu hwemakemikari:Kristaro inopenya isina ruvara kana upfu huchena, tetragonal system, ine hexahedral kana octahedral crystals yakajairika. Inonyungudika zvishoma mualcohol; Inonyungudika mumvura, mhinduro yemvura ine acidic, inonyungudika mu hydrofluoric acid kuti igadzire sodium hydrogen fluoride.
Kushandiswa:
1. Inogona kushandiswa sesimbi ine kabhoni yakawanda, senge simbi inofashaira mhepo, simbi inonyunguduka yakacheneswa nearuminiyamu kana electrolytic, mushonga wekuchenesa bepa usingapindi mvura, mishonga yekuchengeta matanda (ine sodium fluoride ne nitrate kana diitol phenol). Kuti udzivirire ngura yezvinhu zvepasi, shandisa zvinhu (mvura yekunwa, mushonga wemazino, nezvimwewo), mishonga inouraya utachiona, mishonga yekuuraya zvipembenene, mishonga yekuchengetedza, nezvimwewo.
2. Inoshandiswa kudzivirira mazino kuonda uye kuonda kwemuromo kana pasina fluoride mumvura iri mumvura;
3. Madhosi madiki anonyanya kushandiswa pakurapa osteoporosis uye chirwere chemapfupa chepenet;
4. Inogona kushandiswa sechinhu chisina kubikwa kana sechinonyudza fluoride yeimwe fluoride kana fluoride;
5. Inogona kushandiswa semushonga weUF3 adsorbent muzvinhu zvinorapa munyu wefluorine wesimbi, muchina wekunyungudutsa, uye muindasitiri yenyukireya;
6. Mushonga wekusuka wesimbi nedzimwe simbi, zvinhu zvinosungirirwa uye zvinosungirirwa;
7. Zvishandiso zveCeramics, girazi uye enamel melts uye shading, ganda risina kubikwa uye epidermal treatment agents dzeindasitiri yetoni;
8. Gadzira zvinhu zvinosimudzira phosphate pakurapa pamusoro pesimbi nhema kuti mvura igare zvakanaka uye kuti phosphorus membrane ishande zvakanaka;
9. Sechinowedzera mukugadzirwa kwezvinhu zvinovhara uye mapedhi ebhureki, inoita basa rekuwedzera kuramba kupfeka;
10. Sezvinhu zvinowedzerwa mukongiri, wedzera kuramba kwekongiri.
Zvekungwaririra:
1. Shandisa sodium fluoride kudzora huwandu hwefluorine zuva nezuva kudzivirira kugadzirwa kwemuchetura wefluoride;
2. Sodium fluoride solution kana gel zvinofanira kuiswa mupurasitiki;
3. Varwere, vakadzi vane pamuviri, vakadzi vari kuyamwisa, kupfava kwemapfupa uye kutadza kushanda kweitsvo munzvimbo dzine fluoride yakawanda hazvibvumirwi.
Kurongedza nekuchengetedza
Nzira yekurongedza:mabhegi epurasitiki kana bhegi repepa rine ganda remombe rine mativi maviri, mabhare ebhodhi refiber rekunze, mabhare eplywood, mabhare ebhodhi repepa rakaoma; mabhare epurasitiki (akasimba) ekunze; mabhare epurasitiki (emvura); matanda maviri epurasitiki kana bhegi repurasitiki rine mativi rimwe chete, mapuranga epurasitiki, mapuranga epurasitiki, matumba elatex; bhegi repurasitiki, matumba akarukwa epurasitiki (mabhegi epolypropylene matatu mu-imwe, matumba epolyethylene matatu mu-imwe, matumba epolypropylene maviri mu-imwe, bhegi repolyethylene maviri mu-imwe); matumba epurasitiki kana matumba epepa eganda ane mativi maviri kunze kwebhokisi remapuranga reOrdinary; bhodhoro regirazi rine shinda, bhodhoro regirazi resimbi, bhodhoro repurasitiki kana bhare resimbi (gaba) bhokisi remapuranga remazuva ose; bhodhoro regirazi rine shinda, bhodhoro repurasitiki kana tin rakaputirwa nesimbi yakatetepa bhare (gaba) Bhokisi, bhokisi refiberboard kana bhokisi replywood. Kurongedza kwechigadzirwa: 25kg/bhegi.
Nzira dzekudzivirira pakuchengetera nekutakura:Munguva yekufambisa nechitima, tafura yekutakura zvinhu ine njodzi inofanira kuiswa zvichienderana neMitemo yeKutakura Zvinhu Zvine Ngozi yeBazi reNjanji. Usati wafambisa, tarisa kana mudziyo wekurongedza wakazara uye wakavharwa. Munguva yekufambisa, inofanira kuve nechokwadi chekuti mudziyo haufanirwe kudonha, kudonha, kudonha, kana kukuvara. Zvinorambidzwa zvachose kusanganisa neacid, oxidant, chikafu uye zvekudya zvinowedzerwa. Munguva yekufambisa, mota dzekutakura dzinofanirwa kunge dzakashongedzerwa nemidziyo yekurapa inodonha nekukurumidza. Munguva yekufambisa, kupiswa nezuva nemvura zvinofanirwa kunge zvakaiswa pachena kudzivirira kupisa kwakanyanya. Chengeta munzvimbo inotonhorera, yakaoma, uye ine mhepo inofema. Tembiricha yeraibhurari haipfuure 30 ° C, uye hunyoro hahupfuure 80%. Kurongedza nekuvhara. Chengeta zvakasiyana neacid nemakemikari anodyiwa, dzivisa kusanganisa. Nzvimbo yekuchengetera inofanira kunge iine zvinhu zvakakodzera kuchengetedza kubuda kwemvura. Shandisa zvakasimba "five doubles" management system yezvinhu zvine chepfu.
