Deng.Along with the development of science and technology, high-performance glass fiber is in the demand of the industrial circles such as optical cable, high intensity, exotic material
Amount is also constantly expanding.
The major country and the product that produce at present high-performance glass fiber have: " T " fiber of Japan, " R " fiber of France,
" HS " series fiber of Muscovite " BM " series fiber and China.The mechanical property of these high-performance glass fibers is the most excellent
Different, but owing to forming temperature is too high, production difficulty is big, it is impossible to accomplish scale production on modern tank furnace, be confined to military project more
Field.
Entering 21 century, glass fiber industry is flourish, and market application constantly expands, and Ge great glass fibre company all pushes away
Go out the high-performance glass fiber of a new generation；The Technology of glass fibre is also the most progressive simultaneously.At present, optimal high property
Can glass fibre be SiO2-Al2O3-MgO-CaO system glass fibre；The S-998 high intensity SAMC glass produced such as PPG company of the U.S.
Glass fiber, its preparation method includes batch mixing-found-wire drawing, i.e. directly the dispensing mixed is poured in platinum-rhodium crucible and founds
24 hours, clarified, the vitreous humour of homogenizing, the regulation temperature of vitreous humour, liquid level and the rotating speed of wire drawing machine, directly drawn
Go out continuous print glass fibre.The glass melting temperature of this glass is 1600 DEG C, and wire-drawing temperature is 1500 DEG C, and monofilament nascent state intensity is
4500 ~ 4750 MPa, although this glass fibre has a higher mechanical strength, but this glass smelting temperature and wire drawing temperature
Degree is high, melting time is long, and energy consumption is very big, brings huge trouble to production technology.
Produced energy consumption during in order to reduce drawing high-performance glass fiber to greatest extent, Ge great glass fibre company and
Research Center's correction constantly optimizes the preparation method of glass fibre.The Advantex released such as U.S. Ovens-cornin companyTM
Glass fibre, its preparation method has done certain innovation in dispensing, i.e. at SiO2-Al2O3Draw on the basis of the component of-MgO-CaO
Enter substantial amounts of fluoride and alkali metal oxide, obtain glass fibre by the technique of batch mixing-found-wire drawing, its glass melting temperature
Being 1480 DEG C, crystallize ceiling temperature is 1204 DEG C, and wire-drawing temperature is 1260 DEG C, and melting time is 5 ~ 6 hours；Although significantly dropping
Low glass fibre glass melting temperature and melting time, but its monofilament nascent state intensity is only 3100 ~ 3800 MPa.Meanwhile, France
R-glass fibre and AdvantexTMGlass fibre is similar.Its preparation method is i.e. at SiO2-Al2O3Add on the basis of the component of-CaO
Add a certain amount of Na2O、K2The alkali compoundss such as O, obtain glass fibre by the technique of batch mixing-found-wire drawing, and it founds temperature

A kind of method for preparing environment-friendly high-modulus glass fiber, its raw material include silica sand, pyrophillite, Kaolin, alunite, quick lime,
Magnesium oxide and blast furnace slag, then obtain glass blocks through shrend quenching more than 1300 DEG C, is put into by gained glass blocks
Remelting 4 ~ 5 hours again in electric furnace, utilize single hole wire-drawing crucible to draw continuous print glass fibre, and its glass melting temperature is 1470 DEG C, draws
Silk temperature is 1310 DEG C；Although shrend quenching and high-temperature fusion make between glass particle component compacter, significantly drop
Low glass melting temperature and melting time, but its under melt high temperature drastically after cooling each ion have little time playback, cause keeping one
Kind of high energy vitreousness, with irregular confusing array between Si-O key and between Al-O key plasma associative key, thus drops
The low intensity of glass fibre, its fiber nascent state intensity is only 3100 ~ 3500 MPa.
Therefore, ensure glass fibre have high performance in the case of, continue to optimize preparation method, effectively reduce high-performance
