The sizing agents recipe ingredients laboratory
Rosin sizing agent formulations
The raw recipe ratio (parts by mass)
Polyethylene ---------------- 4 parts;
The paraffin ------------------ 16 copies;
The water -------------------- 160 copies;
The rosin ------------------ 18 copies;
Tall oleic -------------- 15.
Preparation Methods: low molecular weight polyethylene, paraffin
wax and water was heated to 90 ℃, at this temperature, stirring
edge hondurensis incense crumb, tall oil acid is added after 10
minutes.Within 10 minutes of the obtained emulsion was cooled to 20 ° C can
be obtained by such a rosin-based sizing agent formulations.
Product Features: The emulsion is stable for 90 days.This product sizing paper with 1% to 6% (dry basis), its physical
and mechanical properties are good, the amount of water absorption
of 10g / sqm.
Second, the starch sizing agent formulations
The ratio of raw materials and formulations
The corn starch ------------------ 100 copies;
Sodium hydroxide ------------------ 2.2;
Sodium -------------------- 50 copies;
Water ------------------------ 125 copies;
Diethylamino trichlorethylene ---------- 5 parts;
The propylene oxide ------------------ 8 parts;
Hydrogen peroxide (35%) ----------- 18 parts.
Preparation Methods: The first four components of the sizing agent
in the formulation mixed, adding diethylaminoethyl vinyl chloride,
stirred for 5 h at 45 ℃, propylene oxide, and then the mixture was
added, under stirring at 40 ℃ 8H,and then add 35% hydrogen peroxide, stirred for 4h corn starch
sizing agent formulations can be obtained.
Product Application: The pH was adjusted with dilute hydrochloric
acid value of 4.5, so that the cationic starch to precipitate out.Obtained cationic starch can be used as a stabilizer of the
emulsion, to add to neutral sizing agent used in the amount of 0.5%
to 9%.
Third, the synthetic resin sizing agent formulations
Component of the raw material and recipe content (parts by mass)
O-octylphenol --------------- 206 copies;
92% paraformaldehyde toluene -------- 65 copies;
Sodium hydroxide --------------- 2 parts;
The gum rosin ----------------- 800 copies;
Fumarate ----------------- 48.
Preparation Methods: octyl phenol with paraformaldehyde in toluene
were mixed at 65 ℃ was treated with sodium hydroxide 10h, heated
together with the gum rosin and added fumaric acid treated at 190 ~
200 ℃ for 2 h, and then treated at 200 to 205 ° C4h i.e. an acid value of 193 and a softening point of 100 ° C
Synthesis of resin sizing agent formulations.
Product features: the use of the sizing agent is coated on the
aluminum content is 0.016% of the paper, so that the amount of
solid sorbent is 0.213%, and in the 80 ° C drying 200S.
Micro-spectrum technology using micro pattern analysis techniques,
and in the large-scale analysis instrument database and map
resources to assist professional to do the sizing agent formulation
analysis, sizing agent component of laboratory, in seven days to
restore basic sizing agent formulations, issued by analysisreport.
