GENGRAL
The SACF fibre that is empoldered and produced ourselves is a new style mulripe frictional fibre, from which the asbestus has been eliminated and it contains NAMI, its English name is: Sanitze-Asbetos compound fibres, abbreviate is《SACF》 .Yearly output of friction material is 8000 tons.
We have SACF-Ⅰ、SACF-Ⅱ;It confirms to standard Q/3200SWC01-2006, it is gong through ISO 9001-2000 authentication .The main use of SACF fibre is being the new enganced fibre of non-asbestus frictional material, replacing the traditional asbestus fibre and expensive Kevlar pulu fibre.
1. The character of SACF fibre
The SACF fibre winnows nonmetal mireral materials .It is aide by some special techniques such as melting in high temperature ,surface activation ,organic treatment and high speed fix and also adding some MANI mulriple materials .This product is nonpolluting .It specially designs by the basal demand of enganced fibre ,which is originally needed for the frictional material .It is steady and of good thermal endurance .It has all the characteristic of enganced fibre that is made by frictional material.
The character as followed
(1) The fibre’s ratio surface area is very big and similar to villus ,so its absorptive capacity is very good.
(2) The fires surface modified by couping agent, so bounding capacity of fibrer with resins and other comonnets in formous is good. It won’t destroy the mate of the frictional material.
(3) The fibre (tie) with cling to damping agent ,the damping agent can reduced cohesion of fibres(tie) ,so fibre has excellent scattering properties. When falling across outside force, it is not easy to curl to conglobation .It is in good decentrality and resistance to wear.
( 4) In order to meet the client’s requests for the outline, we can change the L/D by controlling the diameter and length of the fibre.
(5) The SCAF fibre has high thermal resistance, which increases the fire resisting quality of the fritional material.
(6) The steady chemical composition of SACF fibre can obviously increase the useful life brake disk.
(7) AS a new style mulriple frictional fibre that eliminates NAMI in the asbestos ,it has the most predominance in price both here and abroad .In the meantime ,it is also a frictional enganced fibre that specializes in environment protection .It is canonized by frictional material experts and receives recognition from customers both here and abroad.

4.THE APPLICATION HINTS OF SCAF
(1) The principle of the SACF-Ⅱ is “the equivolume substitute” ,it can instead of Kevlar Pulur to do the prescription of the friction materials. SACF-Ⅰ is the new enganced fibre which used to heavy,light car currester.The closage is only the 68-78% of the traditional asbestus fibre. It shows more advantage in its capability and price.
(2) Mix the blending , the rev of the ordinary high speed blender ,s mainframe is higher than 700r.p.m, it is more propitious to its spread around.
5.PACKAGING DEPOSITE AND SERVICE
(1) coumpond spinning bag,
weight:20kg/per
volume: 90cm×40cm×20cm
(2) deposit in dry place ,prevent from dampressing
period of validity: 1year⑶ if any request ,we can help to do the performance projection of any asbestus fibre.
