good  idea

first,thank you
this is my paper abstract
In this paper, the fluorocarbon emulsion is prepared with the monomer pre-emulsification polymerization method; the infrared radiative powder is prepared by high temperature solid-phase sintering technique. And then, a kind of thin exterior wall thermal-insulating and energy-saving composite coatings which coexists of three mechanisms of barrier, radiation and reflection is prepared using fluorocarbon emulsion and acrylic emulsion as the membrane material, respectively. Functional filler and reinforcing material are selected purposively, and properties of the coatings are evaluated.
The influencing factors of the polymerization process and the emulsion properties are studied. The optimal formula of fluorocarbon emulsion as follows: Methyl methacrylate : butyl acrylate : butyl acrylate hexafluoropropylene (mass ratio) = 0.75 : 1 : 0.9, the dosage of initiator is 0.01 % of the monomer, emulsifier is 3 %, buffer is 2 % and protective colloid is 4 %. The optimal conditions of fluorocarbon emulsion as follows: in the pre-emulsion process, the dropping time of mixed monomers is half an hour and low-speed stirring for an hour at 50℃; in the polymeric phase, under nitrogen atmosphere and high-speed stirring, the dropping time of initiator and buffer is 2 ~ 3 h, the dropping time of the protective colloid is 1 h, polymerization continues for 3 ~ 4 h at 80 ℃, and then holds at 85℃ for 0.5 ~ 1 h. The results of FT-IR show that the fluorocarbon emulsion is synthesized. The SEM graphs of emulsion film reveal that surface of emulsion membrane is smooth and compact, its contact angle to water is close to 90°, to n-octanol is more than 80°. The rest basic properties of the coatings are qualified.
The formula and polytechnic conditions of the infrared radiative powder are optimized by orthogonal test. The optimal formula as follows: Fe2O3 : MnO2 : CuO : Co2O3 : Cordierite = 7 : 1.1 : 1.1 : 1 : 1.2 ; the optimal conditions as follows: the particle size is 400 mesh, the wet mixing time is 6 h, the calcining temperature is 1300℃ and the calcining time is 3 h. The results of XRD pattern show that anti-spinel CoFe2O4 is generated, the infrared radiative powder is the complex of anti-spinel CoFe2O4 and cordierite, both of which are the high infrared active substances. At 26℃，in 8 ~ 13.5 Micron band，the emission rate of the composite is more than 94%.  
Using the self-made fluorocarbon emulsion as the membrane material, hollow glass beads, rutile titanium dioxide and infrared radiation powder as functional filler, aluminium silicate as reinforcing material, and other fillers and additives are supplemented, a kind of fluorocarbon top-coatings is prepared, which has high reflectivity more than 82 % and emissivity greater than 72 %. The SEM graphs show that the film has a smooth and compact surface, the rest basic properties of the coatings are good.
Using acrylic emulsion as membrane material, hollow glass beads as a functional filler, aluminium silicate fibre as reinforcing filler, combine with other fillers and additives, a kind of thermal-insulating primer is prepared, of which thermal conductivity is less than 0.0600W/ (m•K). The SEM graphs show that the surface of the coatings is compact and smooth, and its internal has the characteristic of porous structure of low thermal conductivity material. And the other basic properties are fine.
Combining the prepared top-coatings with primer, the low thermal conductivity, high reflectivity and high emissivity will be incarnated, and coatings containing fluoride which have perfect properties is favor to the thermal-insulating and energy-saving of external-wall.

As for me , communicating with is really a enjoyable issue .Hope I can meet more friends in math

I strongly suggest you to pick up some topics, such as food, fashion, and economics, for discussion.  It is hard to find a very general one for every one, but diversified topics can attract more to participate.  

A good start is business news or economic event analysis.  The reason is this forum is supposed to be the biggest one for any one interested in business and economics.  That would make your innovation more special and hardly competed.  

Daily English or survival English would be found in bulk of other fora and interests in this are highly possible to fade away.  

Anyway, it is a good start.  Wish you contribute more in the coming future.

Cheers!

So nice!

good suggestion!

oh nice!

Thank you for giving us the opportunity to communicate.

I don't know how to express  it !

Really? How could I gain these bonus?

The more posts you made in English, the more points you can earn.

I mean is it only under this topic or for every topic?

it's a good practice to communicate in English, but what the topic is? the clause has no topic, I suggest lord to open a topic in english

There are numerous posts in the forum. You need to search hard on your own to find topics for discussion.

i want to improve my orale English, and writing is also very important.
So this is really very good for me.

好想有一口流利的英语

顶一下

Hello, everyone. I am a college undergraduate students of logistics management, I am very happy to be here, hope to be able to obtain the good teachers and helpful friends here, improve their professional knowledge and ability. Thanks.

for me,Although my Engilsh is poor,I need this stage to improve my Engilsh.I hope someone give me useful advice.thanks very much.

I like it。 It's a very nice article。

good idea. Let us practice our english.  can anyone tell me how to become a great economist?

Very impressive.Such a good idea to reply in English. As an English major, i really should learn to use it in multiple ways. I believe English is not some sort of skill, but a routine work that can be applied in every aspect of life. Watch American/British dramas,read Economist,talk to some guy from an English-speaking country,feels like you'd enjoy your life while discovering the beauty of the language!

actually  it help us to change our thinking ways

This idea is a very wondful light for me. We study englihs , so we use it,  and learning by doing, come on.

It's really a very good idea.
Practice makes perfect!
Hope everyone can improve their English by doing it.

This is a great idea. I can practice my English by visit this website everyday. Moreover, it is free to learn English by visiting this website. I love this website so much! I am going share this great news to everyone. :)

great! it's helpful to everyone!

May be my English is not pretty good,but i believe that someday people will how hard i tried.And i think that I've got to say you are a good person.God bless you.

In fact, my English is not good, but your idea is nice. No one whose  English is good when he was born. As long as you work hard, anyone can learn English well.

I communicate with my friends in English. I hope we can fluently use English someday. Best wishes to everyone.
