珍珠岩助滤剂Pearlite filter aid
珍珠岩助滤剂是由精选小粒径矿砂经净化煤气加热，在垂直立窑内选择性膨胀，膨胀经研磨净化获得的一定粒度搭配的粉末状化学产
Pearlite filter aid is a powder-like chemical product with a certain particle size ratio, which is obtained by selectively expanding the selected fine-grained mineral sand with purified gas in a vertical shaft kiln and then grinding and purifying the expanded material.
园艺珍珠岩Horticultural perlite
园艺珍珠岩是珍珠岩矿砂经预热,瞬时高温焙烧膨胀后制成的一种内部为蜂窝状结构的白色颗粒状的材料.其原理为:珍珠岩矿石经破碎形成一定粒度的矿砂,经预热焙烧,急速加热(1000℃以上),矿砂中水分汽化,在软化的含有玻璃质的矿砂内部膨胀,形成多孔结构,体积膨胀10-30倍的非金属矿产品
Horticultural perlite is a white granular material with a honeycomb-like internal structure, which is made by preheating perlite ore sand and then subjecting it to instantaneous high-temperature calcination and expansion. The principle is as follows: perlite ore is crushed into ore sand of a certain particle size, preheated and calcined, and then rapidly heated (above 1000℃). The water in the ore sand vaporizes, and the softened ore sand containing glassy substances expands internally, forming a porous structure with a volume expansion of 10 to 30 times. It is a non-metallic mineral product.
可广泛用于城市绿化、园艺苗圃、草坪建植、大树移栽、屋顶花园、地下停车场、生态道桥、阳光大厅、庭院盆栽、动动场及盐碱地改良等绿化项目建设，并适宜无土栽培高档花木和无公害经济植物，是生态园艺栽培的上好植料。
It can be widely used in urban greening, horticultural nurseries, lawn establishment, large tree transplantation, roof gardens, underground parking lots, ecological bridges and roads, sun halls, courtyard potted plants, sports fields and saline-alkali land improvement and other greening projects. It is also suitable for soilless cultivation of high-grade flowers and trees and pollution-free economic plants, and is an excellent planting material for ecological horticultural cultivation.
