噴粉機
Xeving Spray IWS Series wet type(中文版)

銷售方式:

  1. 噴粉機 Spacer spray machine
  2. 噴粉套裝 Spacer spray unit
  3. 噴粉密度計量系統 Spacer density measuring system

一直以來噴粉設備上的缺點：

  • 較多凝聚起的噴粉
  • 散佈後的重複性不好，不能重複有同一密度

此設備的優點：

  • 使用新穎的噴嘴，減少噴粉的凝聚
  • 此設備可使噴粉溶液中的噴粉更佳地分散
    現時噴粉機在使用IPA與DI WATER的比率上，需要IPA的比率較高，因而增加爆炸的危險性。此設備的特點是可把使用IPA的比率減低，從而減低爆炸的危險性。
  • 此設備採用Pulse Spray Method ，能使噴粉不會凝聚在一起，而且可時常進行噴頭的清潔，令噴粉不會凝聚在配管中。
  • 性能可達至散佈 3μ 的噴粉，這是現有的噴粉機所不能達到的
  • 內藏高速散佈分散設備（High Speed Dispersion - Mixing System），可以在非常短的時間內能制造分散性優良的噴粉溶液

發生噴粉凝聚的原理 :

在液滴中的噴粉，因噴粉互相之間的物質引力而集中及凝聚。

高速噴粉分散調合設備IHG SERIES（High Speed Dispersion-mixing system）:

要提高分散性，重點在於必需要管理好散佈混合液。 此設備是將併設分散系統放在噴嘴的附近，把散佈溶液中的工序(噴粉程序)再次改良。

"噴粉程序"意思為把噴嘴及散佈溶液（即噴粉混合液）作為一個總體來管理。為現今日本LCD工業的基本概念。而XEVING IWS 的 SPRAY PROCESS 是本著多年對此工業的經驗而展開開發，提供一套完善的噴嘴套件為了解決現時噴粉程序的不足之處。

特徵

  1. 噴粉液分散進行在一個完全密封的狀態裏。
  2. 不用超聲波，可使用新開發出簡易的分散噴嘴
  3. 可以配合不同散佈噴嘴，故此可以配套化
  4. 可以在短時間內完成分散


現時的噴粉機與XEVING IWS噴粉機的比較:

現今的噴粉機
XEVING IWS
噴粉的分散管理
  1. 現時在Breaker中使用Magnet-Starer來攪拌噴粉溶液
  2. 對於在Breaker內的噴粉凝聚問題沒有特別的對策
  1. IHG系統可同時攪拌及連續分散
  2. 對於在Breaker內的噴粉凝聚問題有解決方法
噴粉溶液搬送系統
(配管，氣泵)
  1. 現時採用的低壓氣泵運送，使噴粉在配管內沈降
  2. 在搬送時：在配管及氣泵中沒有對沈降的問題有特別的對策

設計了一個清潔系統，可以定期地在運送內（配管）清洗運送時出現的沈降，從而清除沈降的問題
噴嘴
 一般的噴嘴

使用Pulse Spray Method把噴粉在噴嘴內最終分散，使噴粉不會在噴嘴內凝聚起來
吐出壓力空氣管理

用機械式的Value來調整，不能作精密的調整

用Regulator作管理及調整
噴嘴的口徑 固定

可以更改
Spacer的粒徑及噴嘴的口徑，此等都對噴粉凝聚(cluster)發生有很大的影響
散佈量管理 管理散佈時間
不可能有精確的調整

管理散佈，噴粉的溶液用Pulse數來管理，故此可以有精確的調整

Spacer machine
Xeving Spray IWS Series wet type(English Version)

Items to sell:

  1. Spacer spray machine
  2. Spacer spray unit
  3. Spacer density measuring system

Disadvantages of nowadays spacer machine:

  • Many clusters , i.e. condensed spacer
  • After spraying, the repeatability is not good due to the unstable of spacer density

The reason of the formation of clusters :

Because of the materially attraction of spacer, the spacers inside the solvent will concentrate and become clusters.

In order to prevent the formation of spacer cluster in the semi-dry (wet) type spacer, not only the machine but also the whole system have been newly developed.

We have developed Xeving spray Type IWS - High Speed Spacer spraying dispersion adjusting machine ING Series. For a better dispersion performance, the control of the mixture of the spacer solvent is very important. So a dispersion unit is added to the nozzle to improve the solvent.

This new spacer spray machine:

  1. Using a new type moveable nozzle, minimize the condensation of spacer (less clusters)
  2. Good dispersion of spacer for the spacer solvent
  3. Lower IPA ratio can be used for the mixture of IPA and DI water and hence the danger of exposure can be reduced
  4. Using a new spraying method - the pulse spray method:
    No cluster of spacer will occur
    Can always keep cleaning the nozzle
    prevent the cluster of spacer in the tube
  5. Can spray 3μ spacer
  6. With high speed spraying - 350 pcs / mm2
  7. Have high-speed dispersion-mixing system which enable to make good dispersion type spacer solvent within a short period of time.

Merits:

  1. Carry out the spacer spraying in a closed area
  2. Very simple method, no need to use ultra sonic
  3. Can matching with difference nozzles
  4. Very short time for spraying

Comparison of IMS Series with today's spacer machine

 
Regular spacer machine
Xeving IMS Series
Control of dispersion

  1. Use Magnet-starer and put into a beaker to stir the spacer solvent
  2. Cannot prevent the formation of cluster
  1. Use 1HgSystem continuously dispersed with stirring.
  2. Can prevent the formation of cluster
Spacer ( Solvent carrying pipe)
  1. Using low pressure pump, spacer will sediment in the pipe.
  2. During the process of carrying spacer (pipe, pump), there is no prevention of the problem of sediment
A Cleaning system is set up for the regular cleaning , so the problem of sediment is solved.
Nozzle

Regular type air nozzle
  1. Pulse spray method
  2. The spacer will be dispersed in the nozzle and no clog in the pipe.
Output Air Pressure Control
 Control by the mechanic valve as not so precision. Control by the regulator
Nozzle Diameter Fix
  1. Can be changed
  2. The diameter of the spacer and the diameter of the nozzle will effect the formation of cluster.
Control Spraying volume

Control the spray time so cannot have an accurate adjustment.

Spray and spacer solvent control by pulse number and so accurate adjustment can be achieved.
