Q:How can low molecular polyamide resin be used?
Low molecular polyamide, also called amino polyamide. The molecular weight of 1000~1500, light yellow viscous liquid density (75 C) fand 0.92~0.96g/cm. The amine value is 230~260mg KOH/g. Viscosity (75 DEG C) 3000~1000mPa.s. The composition of low molecular polyamide is complex, containing primary amine, secondary amine and amide group. It can cure epoxy resin at room temperature, and has good adhesion to metal, glass, ceramics, wood and so on. Low molecular polyamide molecules also have a longer aliphatic carbon chain, which can play an internal toughening effect, so that the cured epoxy resin has a certain toughness, therefore, low molecular polyamide is both a curing agent and a toughening agent. Amine value is the indication of low molecular polyamide activity. The higher the amine value is, the greater the activity is, and the reaction speed with epoxy resin is fast, the dosage is little, and the application time is short. Vice versa。
Q:Is the degree of crosslinking equal to the degree of curing in the process of resin curing?
Swelling equilibrium methodCrosslinked polymer because of its internal network cannot be dissolved in the solvent swelling, but can produce a certain degree of crosslinking degree of swelling in the network depends. The three-dimensional network into polymer cross-linking solvent molecules into, will cause the network to stretch the three-dimensional molecular crosslinked system. Volume expansion of network extension leads to reduced between crosslinking points of polymer chain conformation entropy, so that the crosslinking network generates elastic contraction, the average molecular contraction force depends on the size of the crosslinked polymer two cross-linking point between the polymer chain segment value. When the solvent swelling contraction force and cross-linked segments of phase equilibrium when the system reached equilibrium swelling state. When measured the swelling degree of Q value, you can calculate the average molecular chains of polymer cross-linking points between values. Obviously, the greater the value, that the crosslinking degree of cross-linked polymer is smaller (AC The smaller the joint density is
Q:Why should the new resin be disposed of? How do we deal with it?
The above treatment, such as the use of 3m / h flow rate of flow treatment, the effect will be better. After the new resin has been treated, the stability will be improved remarkably.
Q:Will the resin work fade?
Fading and yellowing are common problems with all artificial colorants, and the quality of colorants is a little smaller.
Q:What is the nature of the resin? What are they?
A mixture of a variety of ingredients, usually amorphous solids, having a slightly shiny surface, hard and brittle, and a few semi solids. Insoluble in water, nor water swelling, soluble in alcohol, ether, chloroform and other organic solvents. Heating, softening, and finally melting, burning when there is smoke, and has a special aroma or odor.
Q:What kind of material is the resin made of?
Resins are made of natural resins and synthetic resins. Natural resin is an amorphous organic matter from the secretions of plants and animals in nature, such as rosin, shellac, amber, etc.. Resins are resins derived from the synthesis of simple organic compounds by chemical synthesis or by the chemical reaction of certain natural products.
Q:The same toys, vinyl resin and the two materials which is better?
1. vinyl mold production process: drawings, mud - gypsum, wax, die die, die, die, the production of leather coat production (die size greater than the production of leather coat size is about 3---4%)2. vinyl furnace temperature of 250 DEG ~280 DEG vinyl for 2 minutes. The temperature of 100 DEG C to form 10 minutes3. Vinyl Composition (BOM content)3-1.PVC juvenile powder 8103-2.PVC coarse powder, C65V3-3. plasticizer (white oil) DINP (adjust vinyl soft hardness)3-4. hard oil, TXIB3-5. hard oil 57 degrees3-6. heat resistant oil ED-S3-7. stabilizer CE-1163-8. release agent
Q:Is acrylic resin poisonous? Is it harmful to the skin of many people?
When acrylic resins are dissolved in solvents and used in paints and inks, these solvents are toxic. Now developed water-based acrylic resin or water-based emulsion, without the use of solvents, it is very environmentally friendly and safe.
Q:How many kinds of resin are there? What kind of resin does SHVC contain in REACH, PP, PVC, ABS, POM and PE rubber all belong to resin?
Later, with synthetic resin, created the field of organic polymer materials. Thermoplastic resin with a variety of fillers made of various plastics, PP, polypropylene, PVC, PVC, and so on.
Q:What is resin glass?
It is made of rigid plastic with high transparency: Polystyrene
