I.　Process　Introduction

This　project　takes　industrial　boric　acid　and　non-boric　acid　sodium　salt　as　raw　material　to　produce　finished　products　of　sodium　octaborate　tetrahydrate　through　batching,　mixing,　dissolving,　condensation　polymerization,　powder　preparation　and　packaging.

II.　Technical　Advancement

This　process　opened　up　one　brand　new　raw　material　formula　and　powder　preparation　process　route,　changed　batching　mode　matching　with　boric　acid　and　borax　and　production　route　using　high-speed　centrifugal　spray　drying　to　realize　condensation　polymerization　and　powder　preparation,　not　only　reducing　reaction　temperature,　saving　production　cost,　but　also　effectively　increasing　product is　dissolving　performance.　B　content　of　the　produced　product　can　reach　20-20.5%,　and　dissolving　speed　in　cold　water　does　not　exceed　3min.

III.　Market　Prospect

Sodium　octaborate　tetrahydrate　is　one　of　the　important　fine　boride,　which　has　been　relatively　active　in　the　market　in　recent　several　years.　At　present,　this　product　is　mainly　used　as　fast-thawing　boron　fertilizer　in　agricultural　industry.　With　the　development　of　social　economy,　construction　of　national　economy　will　have　constantly　growing　demand　for　sodium　octaborate　tetrahydrate.　Vigorous　development　of　sodium　octaborate　tetrahydrate　production　can　meet　the　demand　of　agriculture,　domestic　chemical　industry,　paint,　cultural　relic　protect,　medicine　health,　special　glass,　metallurgy,　mining,　electroplating　and　other　industries.　Sodium　octaborate　tetrahydrate　contains　B2O3　as　high　as　67%,　and　compared　with　borax　pentahydrate,　its　good　storage　and　transportation　performance　attracts　more　attention　of　people,　having　broad　application　prospect　in　the　industrial　field.　With　deepening　of　application　research　and　constant　expansion　of　application　fields,　market　demand　for　sodium　octaborate　tetrahydrate　is　bound　to　rapidly　increase.　Development　of　sodium　octaborate　tetrahydrate　production　will　certainly　bring　about　more　economic　benefits　and　social　benefits.

IV.　Technical　Sources

Autonomous　research　and　development,　and　industrialization　has　been　realized　in　Shandong　and　other　places.

VI.　Investment　Scale

According　to　annual　production　of　sodium　octaborate　tetrahydrate　1,000t,　equipment　investment　is　500,000　Yuan.

VII.　Environmental　Protection　

The　process　does　not　have　three　wastes　discharge,　causing　no　disadvantageous　impact　on　the　environment.

VIII.　Economic　Benefits

The　product　production　cost　is　7,300　Yuan/t,　factory　price　is:　big　package　12,000-15,000　Yuan/t,　small　package　38,000　Yuan/t,　which　has　high　additional　value　high　and　significant　economic　benefits.

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.
