lub hom phiaj ntawm anti bumping granules Saib
Lawv nres tsoo , uas tam sim ntawd tsos ntawm vapor npuas nyob rau hauv cov kua kub ua rau upwards splashing. Cov tiv thaiv - tawg granules ua raws li kev tsom mus rau theformation ntawm vapor cia tus npau taws
Tom qab ntawd, ib tus tuaj yeem nug, vim li cas thiaj li siv cov tshuaj tua kab mob hauv lub khob distillation?
Ib tug boiling nti, boiling pob zeb, ntxeem tau khoom los yog tiv thaiv - tawg granule yog ib qho me me, tsis sib npaug ntawm cov khoom ntxiv rau cov kua ua rau lawv npau taws ntau dua. Boiling chips muab cov chaw nucleation kom cov kua boils smoothly tsis ua superheated los yog tsoo.
Tsis tas li ntawd, koj yuav ua li cas tiv thaiv distillation los ntawm kev sib tsoo? Kev tiv thaiv . Txoj kev uas feem ntau ntawm tiv thaiv pob yog los ntawm kev ntxiv ib los yog ob lub boiling chips rau cov tshuaj tiv thaiv. Txawm li cas los xij, cov no ib leeg yuav tsis yog tiv thaiv pob thiab vim li no nws yog ib qho tsim nyog kom boil cov dej hauv lub raj kub npau npau, lub khob ntim dej, lossis lub hwj Erlenmeyer.
Tsis tas li ntawd nug, vim li cas cov tshuaj tiv thaiv kev sib tsoo granules ntxiv ua ntej muaj kev daws teeb meem?
Thaum twg a tshuaj tiv thaiv sib tov yog ua cua sov , muaj a nyiam kom nws npau taws heev li cov npuas loj ntawm superheated vapor dheev tawg los ntawm qhov sib tov. Anti - tawg granules yuav tsum yog ib txwm ntxiv ua ntej cua sov pib vim ntxiv lawv rau a kub sib tov yuav ua rau nws froth tshaj.
Lub hom phiaj ntawm boiling pob zeb nyob rau hauv distillation yog dab tsi?
Boiling chips yuav tsum muab tso rau hauv distillation lub raj mis rau ob qho laj thawj: lawv yuav tiv thaiv superheating ntawm cov kua distilled thiab lawv yuav ua rau amore tswj boil , tshem tawm qhov ua tau ntawm cov kua dej hauv lub distillation flask yuav tsoo rau hauv lub condenser.
