Kaolin , tseem hu ua Tuam Tshoj av nplaum, mos dawb av nplaum uas yog ib qho tseem ceeb muaj nyob rau hauv kev tsim khoom ntawm Tuam Tshoj thiab porcelain thiab yog dav siv hauv kev tsim cov ntawv, roj hmab, xim, thiab ntau lwm yam khoom. Kaolin muaj npe tom qab lub roob hauv Suav teb (Kao-ling) los ntawm nws tau mined rau ntau pua xyoo.
Ua raws li qhov xav tau, kev siv kaolin yog dab tsi?
Kaolin yog siv rau mob raws plab me me mus rau nruab nrab, raws plab hnyav (dysentery), thiab kab mob cholera. Kaolin qee zaum siv rau qhov txhab los pab kom tsis txhob los ntshav. Nws kuj tseem tuaj yeem siv rau ntawm daim tawv nqaij kom qhuav lossis ua kom tawv nqaij.
Tsis tas li ntawd, kaolin puas noj zoo? Yog tias leej twg tau noj Kaopectate rau mob plab, koj tau zaum noj kaolin . Nws muaj peev xwm los hloov lub plab ploj los yog puas lawm, thiab sooth digestive teeb meem nyob rau hauv moderation.
Kuj paub, lub teeb kaolin siv qhov twg?
Kaolin yog siv nyob rau hauv ceramics, tshuaj, coated ntawv, raws li ib tug zaub mov additive, nyob rau hauv cov tshuaj txhuam hniav, raws li ib tug teeb diffusing khoom nyob rau hauv dawb incandescent teeb qhov muag teev, thiab hauv cov tshuaj pleev ib ce.
Koj paub li cas kaolin?
Kaolin zoo nkaus li tsw dawb rau yellowish los yog greyish hmoov. Feem ntau muaj cov av nplaum ntxhia kaolinite (Al2O3 (SiO2) 2 (H2O) 2), hydrous aluminosilicate. Kaolinite muaj mp740-1785 ° C thiab ceev 2.65 g / cm3. Kaoline yog insoluble hauv dej tab sis darkens thiab tsim lub ntiaj teb tsw thaum ntub.

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
