Puas yog glycerol muaj teeb meem rau tib neeg lub cev? Taw qhia rau lub luag haujlwm ntawm glycerol hauv cov luam yeeb hluav taws xob

Puas yog glycerol muaj teeb meem rau tib neeg lub cev? Ntau tus phooj ywg tej zaum yuav tsis tau hnov ​​​​txog lub npe glycerol vim nws yog ib lub npe tshuaj, tab sis yog tias nws hu ua glycerol, qee cov phooj ywg yuav paub nws. Cov khoom no kuj muaj ntau heev, thiab tej zaum tib neeg tsis xyuam xim rau daim ntawv teev cov khoom noj. Qhov tseeb, ntau cov npe khoom noj tuaj yeem pom nws daim duab.

Ntau tus phooj ywg tej zaum yuav tsis tau hnov ​​​​txog lub npe glycerol vim nws yog ib lub npe tshuaj, tab sis yog tias nws hu ua glycerol, qee cov phooj ywg yuav paub nws. Cov khoom no kuj muaj ntau heev, thiab tej zaum tib neeg tsis xyuam xim rau daim ntawv teev cov khoom noj. Qhov tseeb, ntau cov npe khoom noj tuaj yeem pom nws daim duab.
Puas yog glycerol muaj teeb meem rau tib neeg lub cev?
Glycerol, tseem hu ua glycerol, muaj ntau yam kev siv thiab feem ntau pom nyob rau hauv kev lag luam xws li tshuaj, zaub mov, tshuaj niaj hnub, textiles, ntawv ua, thiab xim. Glycerol muaj nyob rau hauv cov roj luam yeeb ntawm cov luam yeeb hluav taws xob.
The harm of glycerol to humans also depends on its dosage. The LD50 of glycerol to rats is>20ml / kg, uas yog kwv yees li 25g / kg (hais lus). Nws yog qhov zoo rau ib tus neeg noj 100 grams ntawm qhov ncauj, vim tias qhov koob tshuaj no suav hais tias tsis muaj tshuaj lom hauv toxicology. Qhov tseeb, tib neeg lub cev noj glycerol txhua hnub, thiab ib qho ntawm hydrolysates ntawm cov roj noj hauv lub plab zom mov yog glycerol, uas yog absorbed los ntawm txoj hnyuv me thiab yog ib qho tseem ceeb heev.
Cov ntaub ntawv toxicological ntawm glycerol:
Toxicity classification: Poisoning
Mob toxicity: qhov ncauj LD50 hauv nas: 26000 mg/kg; Qhov ncauj - nas LC50: 4090 mg/kg.
Cov ntaub ntawv khaus khaus: tawv nqaij luav 500 mg / 24 teev me me; Qhov muag - Luav 126 milligrams me.
Noj tsis muaj tshuaj lom rau tib neeg lub cev. Thaum siv los ua cov kuab tshuaj, nws tuaj yeem oxidized rau acrolein, uas yog khaus. LC50 rau kev txhaj tshuaj rau hauv cov nas yog 7.56g / kg, thiab qhov siab tshaj plaws tso cai rau hauv chaw ua haujlwm yog 10mg / m3.
Rat qhov ncauj LD50: 20ml / kg; Kev txhaj tshuaj LD50: 4.4ml / kg. Khaws rau hauv qhov chaw txias thiab qhuav.
Kev siv cov glycerol:
1. Glycerol tseem ua lub luag haujlwm hauv kev lag luam khoom noj khoom haus raws li cov khoom qab zib, cov dej noo nqus rau cov neeg haus luam yeeb, thiab cov kuab tshuaj.
2. Glycerol tuaj yeem siv rau hauv kev lag luam txheej los tsim ntau yam alkyd resins, polyester resins, glycidyl ethers, epoxy resins, thiab lwm yam khoom.
3. Glycerol tuaj yeem yaj hauv txhua qhov sib piv nrog dej, thiab cov kua qaub qis glycerol tuaj yeem siv los ua cov roj lubricating, uas muaj cov nyhuv moisturizing ntawm daim tawv nqaij.
4. Glycerol tuaj yeem siv rau kev txheeb xyuas cov tshuaj aqueous, cov kuab tshuaj, cov ntsuas roj, thiab hydraulic xovxwm cushioning kua, softeners, desiccants, lubricants, cosmetic formulations, organic synthesis, plasticizers, thiab lwm yam.
Lub luag haujlwm ntawm glycerol hauv hluav taws xob luam yeeb:
Glycerol feem ntau ua lub luag haujlwm pa luam yeeb hauv hluav taws xob luam yeeb. Qhov siab dua ntawm glycerol, qhov tuab thiab loj dua cov pa luam yeeb tsim los ntawm cov roj luam yeeb. Feem ntau hais lus, vim muaj glycerol, haus luam yeeb roj nyiam me ntsis qab zib. Kuv vam tias cov phooj ywg yuav xyuam xim rau qhov no.
Yog hais tias lub purity ntawm glycerol nws tus kheej yog siab txaus, nws yuav yeej tsis tsim kev phiv rau tib neeg lub cev noj qab haus huv. Nws yuav tsum tau muab sau tseg tias ib tug loj npaum li cas ntawm glycerol nkag mus rau hauv tib neeg lub cev yuav ua rau muaj peev xwm ntawm cov ntshav qab zib siab, yog li cov neeg uas muaj ntshav qab zib mellitus thiab ntshav qab zib tau zoo dua tsis txhob siv cov luam yeeb hluav taws xob! Tsis tas li ntawd, thaum xaiv glycerol, nws yog ib qho tseem ceeb uas yuav tau sim xaiv ib qho uas zoo dua.
Hauv cov ntsiab lus, glycerol tsis muaj teeb meem rau tib neeg lub cev, thiab qhov no yog nyob rau hauv qhov kev nyab xeeb ntau npaum li cas. Ntau yam khoom noj, xws li ncuav mog qab zib thiab qhob cij, kuj ntxiv qee cov zaub mov qib glycerol raws li cov dej khaws cia thiab moisturizing tus neeg sawv cev, yog li glycerol muaj ntau heev hauv lub neej txhua hnub. Cov luam yeeb hauv hluav taws xob kuj ntxiv qee qhov glycerol, feem ntau yog haus luam yeeb.
