Ntaub ntawv
Qhov kev xaiv ntawm cov khoom siv rau kev sib cais funnel nyob ntawm qhov xwm ntawm cov tshuaj lom neeg tau ua tiav:
Iav: Iav cais cov kev lom zem yog qhov ruaj khov thiab tiv taus cov tshuaj corrosion. Lawv muab kev pom tseeb ntawm kev sib cais cov txheej txheem, ua rau lawv zoo tagnrho rau kev siv nrog ntau yam tshuaj lom neeg. Txawm li cas los xij, iav tuaj yeem nquag nquag ua txhaum yog tias poob lossis raug mob kom sov.
◆ yas: Yas sib cais cov rooj lom zem muab lub teeb ci sib dua thiab ntau dua cov tshuaj tawg-resistant lwm txoj hauv kev. Lawv tsim nyog tshwj xeeb rau kev siv nrog cov tshuaj corrosive lossis cov uas tawm tsam ua kom muaj zog nrog iav. Txawm li cas los xij, yas kuj yuav tsis muab cov tshuaj zoo ib yam li iav, thiab qee yam plastics tej zaum yuav raug rau kev ua tsis zoo rau lub sijhawm.
Cov ntawv thov hauv Chemistry
A Chemistry cais funnel, tseem hu ua kev sib cais funnel, yog cov khoom tseem ceeb, yog cov khoom siv chemical rau kev sib cais ntawm cov kua dej tsis zoo raws li lawv cov qauv sib txawv. Cov cuab yeej siv no feem ntau ua haujlwm zoo li cov txheej txheem ua kua ua kua, uas cov compound hloov pauv ntawm ib cov kuab tshuaj rau lwm tus. Nws cov qauv tsim muaj cov duab conical nrog lub txiav tawm hauv qab, tso cai kom meej tswj tau cov txheej txheej ntawm cov kua hauv qab cov kua tom qab.
Hauv cov kev siv lub tswv yim, kev sib cais funnel yog tsis tseem ceeb hauv cov organic chemistry rau kev ua kom huv lossis cais cov tshuaj tshwj xeeb los ntawm kev sib xyaw. Piv txwv li, nws tuaj yeem cais cov khoom organic los ntawm cov khoom pov tseg pov tseg tom qab kev tawm tsam. Cov txheej txheem cuam tshuam cov sib xyaw kom haum rau lub funnel, co nws nrog qhov tsim nyog uas tsim nyog, thiab tom qab ntawd cia cov khaubncaws sab nraud pov tseg. Denser kua teeb tsa hauv qab thiab tuaj yeem tso dej tawm, thaum lub sijhawm tsis tshua muaj kua tseem nyob saum toj. Cov qauv no tau siv dav hauv kev lag luam xws li cov tshuaj kiab duab, petrochemicals, thiab kev tshuaj sib cais ib puag ncig, qhov kev ua kom huv si yog qhov tseem ceeb.
Kua-kua extraction
Qhov no yog qhov kev thov feem ntau ntawm kev sib cais funnel. Nws tso cai rau kev sib cais ntawm kev saws ntawm ib cov kuab tshuaj rau lwm tus, raws li lawv qhov sib txawv solubility. Piv txwv li, hauv kev rho tawm ntawm caffeine los ntawm cov taum kas fes, cov haus kas fes, kas fes tom qab ntawd sib cais los ntawm cov aqueous theem uas siv cais funnel.
Ua kom huv thiab kev cais
Qhov sib cais funnel kuj yog siv rau hauv kev lim thiab cais ntawm cov tebchaw. Los ntawm xaiv tau cov lus teb uas xav tau ua kom sib txawv, kev sib cais funnel tuaj yeem pab cais impurities thiab purify cov khoom xav tau.
Kev ntsuas tshuaj anchister
Hauv kev ntsuas anchister, kev sib cais funnel yog siv los npaj cov qauv rau kev tshuaj xyuas. Piv txwv li, hauv kev rho tawm ntawm cov hlau los ntawm cov qauv ib puag ncig, kev sib cais tau siv los cais cov hlau ions los ntawm cov piv txwv Matrix, tso cai rau kev tsom xam kom tau ntau dua.
Synthesis thiab Rauv Ntsuam Xyuas
Hauv cov tshuab hluavtis hluavtis, lub cev sib cais feem ntau siv los saib xyuas qhov kev kawm ntawm cov kev tawm tsam thiab cais cov tshuaj tiv thaiv cov khoom lag luam. Los ntawm kev ntsuas ntu thiab muab cov tshuaj tiv thaiv kab mob sib xyaw, cov kws tshawb nrhiav tuaj yeem nce kev nkag siab rau cov tshuaj tiv thaiv hluav taws xob.
Kev sim ua kom pom
Kev sim lub hom phiaj thiab txoj ntsiab cai
Lub hom phiaj tseem ceeb ntawm kev sim yog kom muaj kev sib cais los ntawm cov roj ntsha sib xyaw los ntawm kev siv lim dej sib cais, thaum tso cai ua kua rau. Lub hauv paus ntsiab lus ntawm cov txheej txheem no ntawm qhov kev siv hluav taws xob txo, uas yog siv lub tshuab lim dej tsis zoo, yog li txo lub siab hauv lub raj mis. Qhov kev sib txawv no sib txawv, tsim nyob rau hauv lub brinell funnel, nrawm nrawm ntawm kev sib cais ntawm cov khib nyiab thiab kua thiab txhim kho kom pom kev.

Kev sim ua ntu zus
Nruab tus brinell funnel ntawm lub lim lim lub taub lim thiab ua kom paub tseeb tias qhov kev sib txuas yog nruj.
Txuas lub raj mis muaj kev nyab xeeb rau lub tshuab nqus tsev thiab tshuaj xyuas cov nruj ntawm tag nrho cov system los xyuas kom meej tias tsis muaj huab cua sov.
Raws li qhov loj me ntawm Brinell Funnel, txiav ib qho loj ntawm cov ntawv lim.
Moisten lub taub lim ntawv nrog me me ntawm cov dej thiab tuav nws ze rau lub funnel kom ntseeg tau tias tsis muaj npuas nyob nruab nrab ntawm daim ntawv lim thiab cov ceramic phaj.
Ncuav cov khoom siv ua kua kom tau lim rau hauv qhov brinell funnel raws tus pas nrig ntawm iav raws li kev tswj hwm kom tsis txhob muaj kev sib xyaw txaws ntxiv.
Pib lub tshuab nqus tsev thiab pib lub tshuab nqus tsev pom kev. Raws li cov kua ntws tawm, cov khoom siv tau yuav maj mam raug cuab ntawm daim ntawv lim.
Soj ntsuam cov filtrate hauv lub taub lim lim kom paub tseeb tias nws yog tseeb thiab tsis muaj kev cuam tshuam.
Thaum cov filltrate sai nce mus rau ceg yeeb nkab ntawm cov chav dej rho tawm, thiab cov ntaub qhwv cov raj ntawm cov roj tov tawm yuav tsum txuas ntxiv.
Kaw lub tshuab nqus tsev twj tso kua mis thiab nres twj.
Ntxuav maj mam los ntawm cov khoom siv tau nrog xab npum kom tshem tawm cov kua dej thiab cov impurities txuas nrog cov khoom.
Tom qab ntxuav, rov pib nqus lub tshuab nqus tsev rau lim kom txog thaum lub tshuab ntxhua khaub ncaws yog qhov tseeb.
Hloov cov khoom siv cov khoom siv los ntawm daim ntawv lim rau daim ntawv huv lossis cov tais saum npoo av rau ziab.
Ceev faj rau kev sim
Ua haujlwm zoo
Tsim nyog cov cuab yeej tsim nyog ntawm tus kheej, xws li chav ua lub tsho muaj zog, hnab looj tes thiab hnab looj tes, yuav tsum hnav thaum lub sij hawm sim. Nyob rau tib lub sijhawm, zam kev cuam tshuam rau lub funnel ncaj qha rau qhov kub lossis qhov chaw taws.
01
Kev Xaiv Xaiv thiab Kev Txuas
Xyuas kom meej tias txhua yam twj paj nruag tau ntxuav thiab nruj nreem txuas. Tshwj xeeb, kev sib txuas sib txuas ntawm lub raj ntev thiab lub raj luv ntawm lub raj mis muaj kev nyab xeeb yuav tsum tsis txhob yuam kev los tiv thaiv kev nqus dej.
02
Lim Daim Ntawv Xaiv thiab Kho
Xaiv cov ntawv lim kom tsim nyog raws li cov khoom ntawm cov khoom yuav tsum tau lim. Rau cov muaj kuab acidic, muaj zog alkaline lossis cov kev daws teeb meem zoo, cov ntaub lim fiber ntau lossis cov tshuab lim dej zoo tib yam. Nyob rau tib lub sijhawm, cov ntawv lim yuav tsum ua kom tiav tag nrho cov qhov me me ntawm cov ceramic phaj thiab ua kom nws nyob ze rau lub funnel.
03
Pom kev ceev tswj
Hauv cov txheej txheem pom kev, lub nqus dej ntawm lub tshuab nqus tsev yuav tsum tau hloov kho raws li xav tau los tswj cov kev ua kom pom kev nrawm. Zam kev ua kom muaj kev lim dej ntau dhau ntawm cov kua dej ua kua lossis lim ntawv tawg.
04
Sijhawm tu thiab txij nkawm
Tom qab qhov kawg ntawm kev sim, cov funnel thiab cov khoom muaj feem xyuam yuav tsum tau ntxuav kom huv sijhawm los tshem tawm cov kua dej thiab tsis sib haum. Tswj lub funnel tsis tu ncua kom ntseeg tau tias nws ua haujlwm zoo.
05
Los ntawm kev ua raws li cov txheej txheem saum toj no thiab kev ceev faj, peb tuaj yeem ua tiav cov tshuaj cais ua kom lim thiab ua tiav cov khoom sib cais zoo ntawm cov khoom thiab kua. Cov thev naus laus zis no tsis yog siv ntau yam kev sim tshuaj thiab kev tsim khoom siv rau peb los sib cais ua haujlwm ntawm kev sib cais ua kua.

A Chemistry cais funnel, tseem hu ua kev sib cais funnel lossis sep funnel, yog ib qho tseem ceeb ntawm chav kuaj thiab cov khoom siv chemistry rau cov kua ua kua. Nws lub luag haujlwm tseem ceeb yog cais cov kua dej tsis sib txawv nrog cov qauv sib txawv, xws li cov kuab tshuaj organic thiab cov tshuaj aqueous.
Lub funnel feem ntau muaj cov qauv kev sib tham nrog lub txiav tawm hauv qab, tso cai tswj cov txheej txheej qis dua. Thaum siv, sib xyaw yog hliv rau hauv lub funnel, thiab tom qab co (nrog venting tso tawm), cov khaubncaws sab nraud pov tseg vim lawv cov qauv sib txawv. Cov kua dej ua kua cov txheej qis thiab tuaj yeem tso dej tawm, thaum lub sijhawm tsis tshua muaj kua tsis tshua qab.
Cov cuab yeej no tau ua haujlwm nyob rau hauv cov khoom siv tawm tswv yim, tshuaj ntsuas thiab cov txheej txheem lim dej. Nws cov qauv siv minimizes sib xyaw ua ke ntawm cov khaubncaws sab nraud povtseg ntawm txheej thaum sib cais, ua kom rov zoo ntawm cov khoom siv uas xav tau. Cov kev siv cov ntawv siv uas suav nrog kev muab cov tshuaj organeousាន los ntawm cov tshuaj tsis zoo, tshem tawm impurities, lossis cais cov khoom tshwj xeeb los ntawm cov khoom sib xyaw ua ke.
Kev siv kom tsim nyog yuav tsum tau ceev faj kom tiv thaiv kev tsim emulsion emulsion thiab kom ua tiav kev sib cais. Qhov sib cais funnel qhov yooj yim thiab cov txiaj ntsig ua rau nws tsis tseem ceeb hauv ob qho tib si kev kawm thiab lub luag haujlwm hauv lub luag haujlwm hauv cov kev sib cais cov tshuaj sib cais.
