Description
Technical field
The present invention relates to a kind of low-density solar water heater water tank polyurethane horizontal type foaming equipment and raw material, belong to solar energy foaming technique field.
Background technology
Solar water heater is to make full use of the product that solar energy provides hot water, with advantages such as its clean and safe, easy to use, no energy consumptions, more and more receives people's favor.Particularly in recent years, solar water heater is fast development always, and the high growth rate with annual 20% ~ 30% becomes the up-and-coming youngster who makes industry attract attention.Solar water heater water tank heat-insulation layer main material is to gather ammonia enzyme foamed plastics, in gathering ammonia enzyme foam production, and the vertical foaming of main employing in traditional handicraft.Vertical frothing foam climb altitude is big, causes the foam density gradient big, and mostly the top is tired bubble, heat insulation effect difference etc.; The polyurethane consumption increases, the corresponding increase of water tank heat-insulation layers cost; Because of foaming height is big, the integral foam time is long, is unfavorable for enhancing productivity; Foam is a little less than the vertical direction climbing ability, and transverse pressure is big, is prone to cause quality problems such as fried bucket, lobbing, and product percent of pass reduces, and has increased entreprise cost; Mouth of pipe place foam quality is relatively poor, influences product heat insulation effect and outward appearance.
Summary of the invention
According to the deficiency of prior art, the technical problem that the present invention will solve is: a kind of low-density solar water heater water tank polyurethane horizontal type foaming equipment and raw material are provided, change the traditional vertical foam process, adopt horizontal type foaming technology and raw material.
The technical solution adopted for the present invention to solve the technical problems is: a kind of low-density solar water heater water tank polyurethane horizontal type foaming equipment is provided; It is characterized in that water tank and outer courage are fixed on the mold platform with horizontal; The mold platform two ends have dismountable fixed mould, and mold platform is provided with a plurality of column limit plugs and evenly distributes, and the mold platform top is provided with sprue; During foaming, foaming raw material is injected by sprue after mixing.
Described water tank overlaps with outer courage heart.
The column limit plug is generally 15, but concrete also need with the vacuum heat collection pipe of the solar water heater that will prepare mate each other.
Described mold platform is a semi-cylindrical.
The used foaming raw material of described low-density solar water heater water tank polyurethane horizontal type foaming is made up of the raw material of following parts by weight:
Described PPG A is one or more among the suitable chemical KS-8326 of Co., Ltd of Yadong, the Hebei YD-6205 of chemical industry Group Co.,Ltd polyethers, the DD-450L of Shandong Lanxing Dongda Chemical Co.,Ltd or Tianjin health.
Described PPG B is one or more in the polyethers 4110 of the polyethers 450M of Shandong Lanxing Dongda Chemical Co.,Ltd, BinHua Group Co., Ltd's polyethers 4110, the polyethers 330B of Shandong Lanxing Dongda Chemical Co.,Ltd or permanent rich polyurethane Industrial Co., Ltd..
Described PPG C is the polyethers 635 of permanent rich polyurethane Industrial Co., Ltd. or among the YT-635S of Changshu Yitong Polyurethane Product Co., Ltd. one or both.
Described foam stabiliser is the 6810c of scientific and technological CGY-5 of Group Co.,Ltd of the AK-338 of Nanjing Dymatic Shichuang Chemical Co., Ltd., Yangzhou morningization or Nanjing triumphant Sheng polyurethane auxiliary agent Co., Ltd.
Described composite catalyst is two or more in dimethyl cyclohexyl amine, trisphenol, dimethyl benzylamine, pentamethyl-diethylenetriamine, the triethylene diamine or in the triethanolamine.
Described blowing agent is HCFC-141b.
Horizontal type foaming raw material reaction climb altitude reduces, but raw material lateral flow property is had certain requirement, therefore compares with vertical foaming, needs foaming raw material combined polyether prescription is tested adjustment in a large number, and gets low-density prescription everywhere.
The invention has the beneficial effects as follows: adopt this horizontal type foaming technology and raw material, technological design advantages of simple, easy processing, easy to operate.The water tank heat-insulation layers Density Distribution is even, and heat insulation effect improves; Water tank keeps better with outer courage with one heart, and the outer courage of water tank does not have problems such as cracking, quick-fried bucket and occurs; Special-purpose polyethers lateral flow property is good, and foam density is low, and abscess is fine and closely woven evenly, and tired bubble is few.The reduction of foam-filled amount can reduce by 15%～20% material cost, and production efficiency improves 20%～30%.
It is 24～26kg/m that the horizontal type foaming of this invention freely steeps density by hand
3, casing mean core density is 32～36kg/m
3The foaming of tradition one rifle high pressure vertical, freely steeping density is 27～35/m
3, casing mean core density is 35～45kg/m
