I.　Process　Introduction

This　process　takes　borax　decahydrate,　sodium　hydroxide　and　hydrogen　peroxide　as　raw　material.　Production　processes　include　sodium　metaborate　(solution)　preparation,　addition　reaction,　separation,　washing,　dehydrating,　drying　and　packaging　procedures.　First　dissolve　and　filter　borax　decahydrate,　then　react　with　sodium　hydroxide,　transform　borax　decahydrate　into　sodium　metaborate,　then　react　with　hydrogen　peroxide　to　generate　sodium　perborate　crystal,　then　produce　finished　product　through　drying　and　packaging.

II.　Technical　Advancement

This　process　is　mature　sodium　perborate　production　technology.

III.　Market　Prospect

It　is　widely　applied　in　printing　and　dyeing　industry　as　oxidant,　mordant　and　bleaching　degreaser;　in　daily　chemical　industry　it　is　used　as　oxidant　of　cold　wave　lotion　and　hair　dye,　washing　agent　or　addictive　of　washing　powder;　in　medicine　it　is　used　as　disinfectant,　bactericide　and　deodorant;　in　chemical　industry　it　can　be　used　as　substitute　of　hydrogen　peroxide　and　polymerizer　of　organic　synthesis.　The　market　prospect　is　considerable.

IV.　Technical　Sources

Autonomous　research　and　development,　this　technology　has　been　industrialized　in　Shandong　in　2003.

V.　Product　Quality

It　is　in　conformity　with　international　GB1623-79　product　quality　standard.　Sodium　perborate:　≥97%,　iron:　≤0.003%,　and　stability:　≥90%.

VI.　Investment　Scale

According　to　annual　production　of　1000t　sodium　perborate,　equipment　investment　is　800,000　Yuan.　The　scale　can　be　determined　according　to　the　actual　situation.

VII.　Environmental　Protection　

No　“three　wastes”　discharge.

VIII.　Economic　Benefits

Comprehensive　cost　of　product/t　is　3,550　Yuan,　and　factory　price　is　above　4800　Yuan/t.

IX.　Form　of　Cooperation

Technical　transfer.　Taking　responsibility　for　process　flow　design,　supporting　equipment　of　standard　equipment,　non-standard　equipment　manufacture　design,　equipment is　plane　layout　design,　equipment　installation　design,　pipe　network　design,　equipment　installation　guidance,　equipment　commissioning,　production　commissioning,　training　for　production　engineers,　analysis　staff　and　technicians,　process　operation　specifications,　raw　material　and　product　analysis　method,　and　preparation　of　intermediate　control　analysis　method;　ensuring　output,　yield　and　quality　to　reach　the　standard;　and　undertaking　turn-key　projects.
