Description
Technical field
The invention belongs to the material feeding equipment technical fields that foams, and are mixed and are infused with more component polyurethanes more particularly to a kind of refrigerator
Spray gun head.
Background technique
Refrigerator ice cabinet is the indispensable electric appliance of family, and very important process is exactly poly- ammonia in refrigerator ice cabinet production link
Ester foaming, either the cabinet of refrigerator or door body require to form foam heat-insulation layer after polyurethane foam, to reach
Heat preservation and supporting role.Therefore refrigerator foaming quality is particularly important, meanwhile, refrigerator foaming technology is evolving, domestic at present
The foaming system of one line brand most mainstream is Diversity foaming, i.e., mixes a variety of different types of foaming agents according to different proportion
It is bonded in combined polyether (hereinafter referred to as " pure white material ") and forms mixture (hereinafter referred to as " mixing white material "), then will mix white material
Pass through with isocyanates PM-200 (hereinafter referred to as " black material ") and mix in the cabinet or door body that the injection of material feeding pipette tips to be foamed, finally
Complete foaming process.
Premix mix white material during, when some foaming agent adding proportions are very low or foaming agent be relatively difficult to dissolve in it is pure
White material will result in the not uniform enough of premix, will will affect foaming matter when premixing the non-uniform white material of mixing and reacting with black material
Amount, and existing material feeding pipette tips only mix white material and black material sprue, it can not the very low or more insoluble foaming to adding proportion
Agent is separately injected into.
It would therefore be highly desirable to develop a kind of multiple groups part mixing material feeding pipette tips, can be very low by adding proportion or it be difficult to dissolve in
Foaming agent is not premixed with pure white material in advance, but is directly mixed and while being injected pending by high pressure inside pipette tips when material feeding
In the cabinet or door body of bubble, to improve the uniformity for mixing white material, and then foaming quality is improved.
Summary of the invention
The purpose of the present invention is to provide a kind of more component polyurethane mixing material feeding pipette tips of refrigerator, by pipette tips ontology
