Cautics . Cautics feem ntau yog hydroxides ntawm lub teeb hlau. SODIUM HYDROXIDE thiab potassium hydroxide yog siv dav tshaj plaws caustic cov neeg sawv cev hauv kev lag luam. Kev kho mob, lawv tau siv sab nraud los tshem tawm cov kab mob lossis cov ntaub so ntswg tuag thiab rhuav tshem cov warts thiab cov qog me me.
Tom qab ntawd, dab tsi yog ib qho piv txwv ntawm cov tshuaj caustic?
Lub ntsiab txhais ntawm caustic yog ib yam khoom uas kub hnyiab los yog noj tam sim ntawd los ntawm cov tshuaj tiv thaiv kab mob los yog kev hais lus phem lossis kev sib raug zoo. Ib piv txwv ntawm caustic yog cov nyhuv mustard gas muaj rau ntawm daim tawv nqaij.
Kuj Paub, dab tsi yog tus neeg sawv cev caustic corrosion? Cov tshuaj Caustic yog tshuaj thiab lub cev tus neeg sawv cev nrog lub peev xwm ua rau cov ntaub so ntswg puas. Cov tshuaj alkaline ua rau lub liquefactive necrosis, ua rau cov ntaub so ntswg sib sib zog nqus. Lwm yam mechanisms ntawm corrosive Kev raug mob muaj xws li denaturation, oxidation, txo, los yog alkylation ntawm cellular proteins.
Ib yam li ntawd, dab tsi ua rau chemical caustic?
A corrosive cov ntaub ntawv yog ib tug heev reactive tshuaj uas ua rau pom pom kev puas tsuaj rau cov nqaij nyob. Corrosives ua ncaj qha, los ntawm chemically rhuav tshem ib feem (oxidation), los yog tsis ncaj los ntawm kev ua o. Cov kua qaub thiab cov hauv paus muaj ntau corrosive cov ntaub ntawv.
Dab tsi yog caustic siv rau?
Caustic dej qab zib (sodium hydroxide) yog ntau yam alkali. Nws cov kev siv tseem ceeb yog nyob rau hauv kev tsim cov pulp thiab ntawv, alumina, xab npum thiab detergents, roj av thiab tshuaj ntau lawm. Lwm yam kev siv xws li kev kho dej, khoom noj, textiles, hlau ua, mining, iav ua thiab lwm yam.

Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
Cov cim tshuaj thiab cov qauv tshuaj yog dab tsi?
Cov cim tshuaj lom neeg yog ib qho-lossis ob-txoj kev tsim qauv ntawm ib lub caij. Compounds yog kev sib txuas ntawm ob lub ntsiab lus. Cov tshuaj formula yog ib qho kev qhia uas qhia cov ntsiab lus hauv ib qho kev sib txuas thiab cov txheeb ze ntawm cov ntsiab lus. Ntau lub ntsiab lus muaj cov cim uas tau los ntawm Latin lub npe rau lub caij
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
