Chen Wan Rong's ground points out bottom, Xiao still the glory pour graphite in the pot and pour into solid fire alkali again.Rise fire, turn over with a spade son.This matter has a little oddly.Xiao still glory hard comprehension, thought and think.Is finally unbearable, ask a way:"Elder brother, use wear to want dry?Directly ladle up to come over, burned a fire to become, so troublesome."
The impurities of graphite are ash cent, but ash the cent is mainly acidity oxide and alkaline oxide.Acidity oxide is two oxidize Huo, divided by two to oxidize Huo landlord to want a way be use fire alkali.Mix the graphite and the fire alkali.Heat fire alkali meltdown, two oxidize Huo and fire alkali born can with the meltdown is at the aqueous Huo sour sodium, use again once water wash, attain the purpose of removing the acidity impurities.
Chen Wan Rong of this truth is very clear, be can not speak to the Xiao still the glory listen to, because he isn't understand.The Chen glory late smiles:"Make you do and then do, which so much useless talk."
Still the Xiao glory stops to start living of inside son, one face earnest tunnel:"Elder brother, you must give my elucidation white, otherwise I am getting more careless.I am your disciple.Can I not remember clearly Chu, isn't the face that throws you if someone starts to ask me?"
"Hey.You very did time become my disciple?"The Chen glory late smiled and started to open fun:"Did you send red meat?"
Xiao still the smiling face of glory one face, warm get tight, gather together to come up, on Chen Wan Rong Sang Sang:"Elder brother, we are brotherses.Which need red meat.You teach me once, I was your disciple."
"Thick-skinned!"Chen Wan Rong's point reviews a , explain for him:"Do glass, you also saw.Imply silica sand in graphite, using the fire alkali be for removing this silica sand.Can not use aqua, can be used solid and remembered."
Xiao still glory understand don't understand of way:"BE so, early say.See quickly, there is water."
Where is water.Is a fire alkali meltdown.Is radiant if water, the order way of Chen Wan Rong:" Keep on stir-frying like this."
The fire such soil melting point doesn't arrive 320 degrees.Don't need how to heat and then can attain, the fire alkali of meltdown is more and more.Turning over is a burst of, the meltdown ground fire alkali is missing and appears many glass-like in shape ground of solid in graphite, is very good-looking, Xiao still glory eyes stare the eldest brother is very interested in:"The elder brother see quickly, much good-looking shout!"
Chen Wan Rong doesn't think it's strange:"This call water glass, and then call bubble to spend alkali, arrive have no good."The Huo sour sodium calls water glass in the south of China and calls bubble flower alkali in the north.
"Is this useful?"Xiao still the glory continuously looking at a pot inside, is a sorry tunnel very much:"I still think glass, the white liked.Led a short while, no longer appear water glass, Chen Wan Rong called Xiao still the glory ceased fire and carried pot down, put on the ground and allowed its cooling.As long as no longer heating, this cools off very quickly.
The Chen glory late seeks to a piece of cloth and a sieve, spreads the cloth on the sieve and arrives at a well side.Xiao still the glory pour cooling good graphite in the bowl and carry to come over, at Chen the glory late point out under, pour in the cloth.
Start to beat well water, dynasty the graphite lightly keep on sprinkling and sprinkle a burst ofly, the transparent water glass is missing, the graphite in remaining black.Xiao still glory also no longer astonishment, just Chou write don't talk.
For the first time clean good, Chen Wan Rong pours graphite bowl inside once and enter into a house inside, put on the table.Open cover, ladle up an oil of vitriol with the porcelain Shao, pour in the bowl, this just has the sulfuric acid sealed completely.
The impurities of graphite in addition to two oxidize Huo, be oxidize iron, oxidize aluminum and oxidize magnesium these metal oxides.To remove these oxides certainly use sour, born can be dissolved to water ground salt, use water to complete on cleaning.
Handling graphite with the hydrofluoric acid is the most simple, since can with two oxidize Huo reaction, also can respond with metal oxide, needed to be cleaned to go at a time.Just the hydrofluoric acid isn't small to the disadvantage of human body, furthermore to environment of pollution very big, have already been eliminating now.To Chen Wan Rong, sour only sulfuric acid, hydrofluoric acid even if want to use, also have no that condition.
Mixing blend is a burst of, this just fill with water dilution good, pour in spreading cloth ground sieve, use water a burst of flush, this graphite even if handle.Put inside in the house, spread, waits cool stem can use.
Hope good graphite of this processing, Chen Wan Rong still really has some concussion.Graphite Li Long Ji helps to seek, Chen Wan Rong needs to chase impurities obviation and raises a pure degree, then can do graphite Gan Guo.There is graphite Gan Guo and graphite fire-proof material, the this glass large-scale production wasn't a difficult matter.There is glass, Chen the glory late expected medium laboratory to also seem ready to come out.
"The good elephant is little."Still the Xiao glory Chou wears graphite.
Chen Wan Rong has a little funny:"Impurities to remove, the nature was getting less.Now this graphite, very pure, is a positive article."
Still the Xiao glory touches a forehead:"Elder brother, does the this Gan Guo Zha do?"
"I wasn't clear either, invited Yuan shopkeeper to help."Chen Wan Rong said big truth.Gan Guo, Chen Wan Rong will be used, be can't do, don't seek a Yuan natural help.Can also seek who?
Walk everywhere, lead a burst of.The graphite did, Chen late glory with a piece of cloth wrap well, the Chuai is in the bosom and left home and kept a kiln field.Arrive at kiln field one lo, jollification as usual, the waiters are busy at the shipment.Chen Wan Rong's familiar pole Yi over here.Don't wait a notification as well, directly enter a house.On entering a house, sees Yuan natural to depend to nap on the chair, the breath is tiny, sleep just sweet Han, admired to pull son to follow a corner of mouth to flow down to bedew dress Jin.
Chen Wan Rong sees natural this shape of Yuan for the first time, pure cough a , the Yuan was natural to have no to loudly move.Can't,Beats By Dr Dre Solo, only come to order the severe, Chen Wan Rong exaltation the door roar 1:"Drink!"
"Very wine?"The Yuan natural favour drinks one cup.Is suddenly surprised to wake up, rub eyes every where inside search.
The Chen glory late sits last to chair:"Here."
The Yuan is natural this just discovering is late Chen the glory came and saw Chen Wan Rong that smile don't smile of facial expression.Know the glory late made a fool of to Chen, face a red:"Let shopkeeper Chen laugh."
Chen Wan Rong and he is too familiar, play trick, face a sink:"Laugh need not.Just, I want to ask understand, ascended you last night to where have been already gone to?Will my having to go to fond of each other?This matter is pretty serious.Doing not ask clearly can not."
The Yuan is natural on leaping old Gao, the feet are on the ground one Duo:"Shopkeeper Chen, you never blather, can this kind of matter shout madly Rang?Your lo I this age, even if have that heart, also have no that mental exertion."
Lo he is that frightened shape, Chen Wan Rong not from get a to smile:"Yuan shopkeeper, with you don't take seriously jokingly."
"You are this Chen's shopkeeper.The fun isn't like this either to open of."Yuan natural Wu from put blame on 1.This makes Chen Wan Rong ask a way on one cup tea:"Shopkeeper Chen.But occupy?, You want of thing, I worked well for you and had already sent to shopkeeper there."
What he said is to pack alcoholic wine Ou, Chen the glory late once saw, is satisfaction very much and say with smile:"Yuan shopkeeper, I come to not is to say this today, I still occupy to seek your help."
"Very matter?"The Yuan is natural to know that Chen Wan Rong has no matter not to ascend three treasure palaces, he comes to by all means occupy.
Chen Wan Rong takes out graphite from the bosom, puts in the table and opens.The graphite that looking at black gray, the Yuan is natural to really don't understand that the ground asks a way:"Shopkeeper Chen, is this very again?Your this person, the strange idea is especially many."
"This calls graphite."The explanation way of Chen Wan Rong:"This thing is rich to also can not buy, you can must is careful, not be running to waste.This is to try a hand for you."
The Yuan natural surprise doesn't place, rubs hands and fig ups very much:"Shopkeeper Chen, so gold expensively thing, you believe me thus, I definitely work well for you, you say, do you want to do very?"
"Gan Guo."
The words sound just fell a point, Yuan once the natural Hey Hey smiled, didn't think idea:"Do not do a Gan Guo?Do one to add a point to go in each time in brief be."
"Be not so do ground!"Chen Wan Rong's voice adjusted to all raise a lot and rectified his parlance:"This graphite not is join to glue earth noodles.But want to take graphite as corpus, glue soil in order to assist, never make to reverse."
