Cov Pem Hauv Ntej Cia Cia Thiab Kev Thauj Mus Los

Xi'an Naturetech Co., Ltd | Updated: Aug 17, 2017

Phosphoramide hydroxide (tshuaj formula: KOH, tus nqi: 56.1) hmoov av los yog kua nplaum. Ib lub pob ntim ntawm 380 ° C, lub npau npau ntawm 1324 ° C, ib ntu ze ntawm 2.04 g / cm 3, qhov muag tsis pom zoo n20 / D1.421, thiab vapor siab ntawm 1 mmHg (719 ° C). Nrog muaj zog alkaline thiab corrosive. Yooj yim kom nqus ya raws pa thiab deliquescence, nqus carbon dioxide los ntawm potassium carbonate. Tshaj li ntawm 0,6 feem ntawm cov dej kub, 0.9 feem ntawm dej txias, 3 seem ntawm ethanol thiab 2.5 qhov chaw ntawm glycerol. Thaum yaj hauv dej, haus dej cawv los kho cov kua qaub los ua kom muaj cua sov ntau. Lub pH ntawm 0.1 mol / L daws yog 13.5. Nruab nrab toxic, ib nrab ntawm qhov ua kom tuag (nas, qhov ncauj) 1230mg / kg. Soluble nyob ethanol, me ntsis soluble hauv ether. Muaj ib qho alkaline heev thiab corrosive, nws cov xwm thiab caustic dej qab zib zoo sib xws. Nruab nrab toxic, ib nrab ntawm qhov ua kom tuag (nas, qhov ncauj) 1230mg / kg.

Cov chaw kawm ntawv

1, siv los ua ib qho kev haus luam yeeb, nqus dej, rau cov khoom noj oxalic thiab ntau hom tshuaj muaj potassium, tab sis kuj siv rau electroplating, sculpture, lithography

2, tsuas yog siv rau cov khoom ntawm raw cov nyom xws li potassium, xws li potassium permanganate, potassium carbonate thiab li ntawm. Nyob rau hauv kev lag luam kev lag luam, rau cov khoom ntawm potassium boron, spironolactone, heparanol, testosterone propionate thiab li on. Nyob rau hauv lub teeb kev lag luam rau zus tau tej cov tshuaj kua qaub, alkaline roj teeb, tshuaj pleev ib ce (xws li cov dej qab zib txias, tshuaj nplaum thiab tsuaj zawv plaub hau). Hauv kev lag luam zas xim, rau kev tsim kom tsis txhob dyees, xws li txo qis xiav RSN thiab lwm yam. Hauv kev lag luam electrochemical, rau electroplating, sculpture thiab hais txog. Nyob rau hauv cov kev lag luam textile, luam tawm thiab dyeing, tshuaj dawb thiab mercerizing, thiab coob tus siv rau cov kev siv ntawm cov txiv neej ua fibers, polyester fiber ntau cov ntaub ntawv raw. Tsis tas li ntawd, nws kuj yog siv rau lub tshuab ua kom siv roj ua kom sov thiab tawv degreasing thiab lwm yam.

3, tshuaj ntaub ntawv tshuaj, tshuaj, tshuaj chemicals thiab lwm yam.

4, siv los ua cov tshuaj reagents, kua ntoo ua kua tshuaj, carbon dioxide thiab dej noo noo.

5, tshuaj txhim kho tshuaj rau kev siv tshuaj ntxuav tes, tshuaj zawv plaub hau, tshuaj txhuam, nplaum, tshuaj nplaum thiab lwm cov ntaub ntawv raw. Cov kws kho kev lag luam rau kev siv ntawm progesterone, vanillin thiab lwm cov ntaub ntawv raw. Kev lag luam yog siv los ua melamine dyes. Lub roj teeb kev lag luam yog siv los ua cov roj teeb alkaline

Txheeb xyuas cov ntsiab lus

Ua zoo ntsuas cov qauv ntawm 1.5g, yaj 40 ml tshiab dej txias thiab txias txias, txias rau 15 ℃, ntxiv tshuaj phenolphthalein (TS-167) ob peb tee, nrog 1mol / L sulfuric acid titration. Thaum cov xim liab ploj lawm, sau cov kua qaub lawm, ntxiv ob peb tee methyl txiv kab ntxwv tshuaj (TS-148), ua rau titrate mus qhia ib tus kab liab tas mus li. Sau tag nrho cov ntim ntawm cov kua qaub tsim nyog rau titration. Rau 1 mol / L sulfuric acid sib npaug rau cov nyiaj tag nrho ntawm alkali (hauv KOH) 56.11mg.

Cia thiab tsheb thauj mus los

1, thauj Cim: tsheb thauj mus los, hlau nruas siv tau los thauj lub tsheb. Lub thawv ntim yuav tsum tiav thiab lub nra yuav tsum muaj kev nyab xeeb. Thaum caij tsheb thauj mus rau kom lub thawv tsis ntub, tsis txhob qhuav, tsis txhob poob, tsis muaj kev puas tsuaj. Nws yog txwv tsis pub nrog tov nrog combustible los yog combustible, acid, edible chemicals thiab thiaj li. Cov tsheb thauj khoom yuav tsum tau nruab nrog cov khoom siv hluav taws xob thaum muaj xwm ceev;

2, cia Nco Ntsoov: khaws cia rau hauv ib qho chaw txias, qhuav, zoo-qhov chaw pov tseg. Tam sim ntawd los ntawm hluav taws kub. Lub voj nyob rau hauv lub reservoir yog nyiam dua tsis tshaj 85%. Lub thawv ntim yuav tsum tau muab ntim thiab tsis damp. Yuav tsum yooj yim nrog (tau) roj, kua qaub thiab lwm yam cia, tsis txhob cia cov khoom noj. Cov chaw khaws cia yuav tsum tau nruab nrog cov khoom tsim nyog kom muaj cov nchuav;

3, lub ntim cov txheej txheem: cov khoom yuav raug muab ntim rau hauv 0.5 hli tuab hlau nruas hauv qhov ntim, hnyav ntawm tsis ntau tshaj 100 kg ntawm ib lub phom; hnab yas los yog ob txheej txheej kraft ntawv hnab sab nraud qhib qhov rooj los yog qhib lub nruas hlau; cov iav fwj, Cov fwj yas los yog cov xim plhaub taum plua plav (cov kaus poom) sab nraum lub plag tsev, lub thawv ntawv lub thawv ntawv lossis lub thawv plywood; Tin thin hlau Cov tog poom (cov kaus poom), cov thoob hlau (cov kaus poom), cov fwj yas lossis hlau hoses sab nraum cov thawv ntawv corrugated.
