Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methyl cellulose (HPMC) is made from pulverized refined cotton, alkalized with sodium hydroxide (liquid caustic soda) solution, etherified with methyl chloride and propylene oxide, then neutralized, obtained after filtering, drying, crushing and sieving.
This product is industrial grade HPMC,mainly used as the dispersing agent for PVC production and
as the main assistant used in producing PVC suspension polymerization,lt is also used as thickener ,
stabilizer,emulsifier ,excipient,water retention agent,and film-forming agent etc. in producing
petrochemicals, building materials,paint removers, agricultural chemicals,inks, textiles,ceramics,
paper ,cosmetics and other products. In terms of the application in synthetic resin,it can make the
products loose with regular particles,appropriate apparent gravity and good processing properties,
which almost replaces gelatin and polyvinyl alcohol as dispersant.Another use is in the construction process industries,mainly for mechanized construction like building walls,stuccoing and caulking;
with high adhesive strength,it can also reduce cement dosage,especially in decorative construction
for pasting tiles,marble and plastic trim.When used as a thickener in the coatings industry,it can
make coating shining and delicate,prevent power from alling off,and improve leveling properties.
When used in wall plaster,gypsum paste,caulking gypsum,and waterproof putty,its water retention
and bonding strength will be significantly improved.Moreover,it can also be used in areas like
functional ceramics,metallurgy,seed coating agents,water-based inks ,cosmetics ,electronics,printing
and dyeing,paper etc. -
F-SealCleat Seal
F-Seal is composed with plant hard shells,Mica and other plant fibers.
It is yellow or yellowish powder.Non-Toxic ,It is non-corrosion inert material ,water swelling material.It is an effective lost circulation agent used for multi-fractures layers of oil wells
1. Property
One-way pressure sealant is made from natural fiber ,filling particles and additive.
One-way Pressure Sealant is a product in the form of gray yellow powder, When used in drilling, it can effectively block up leakage of every kind from the formation under the action of one-way pressure difference. It also can improve mud cake quality and reduce water loss. It has very good compatibility and not affect the mud property .It is applicable for drilling fluids and completion fluids with different system and different density .
2.Performance
The drilling fluid is DF-1 with a one-way pressure sealant, which is suitable for the porosity of different conditions in drilling and the seepage loss of micro-fracture formation. The good compatibility of the product is suitable for different system, different density of drilling fluid and completion fluid, the leakage of micro-cracks to achieve effective plugging, and can improve the quality of mud cake, reduce water loss. The recommended dosage for this product is 4%. -
Polyanionic Cellulose Low Viscosity API Grade (PAC LV API)
Our laboratory developed high performance and lower price products of PAC LV API to meet customers' demand for high-cost performance.
PAC LV conforms to API grade and is used in offshore drilling and deep land Wells. In low solids drilling fluid, PAC can significantly reduce the filtration loss, reduce the thickness of thin mud cake, and has a strong inhibition on page salination.
