Six) lay 2-6 layer glass fabric above foam, resin and its composite curing form the first compound carpet veneer 16;
Seven) establish core on the first compound carpet veneer, form the first core layer 17, establish three axle cloth on the first core layer, form multiaxis layer of cloth 18, lay layer of glass cloth on the multiaxis layer of cloth, resin and its composite curing form the second compound carpet veneer 19;
Eight) lay the auxiliary material of vacuum, vacuum suction, pressurize are installed and are rushed nitrogen equipment;
1, the auxiliary material of vacuum is laid:
Table 1
1), release cloth lays: the release cloth that cuts, loose being laid on the second compound carpet veneer 19 uses glue spraying local fixing; But release cloth fold but can not tighten, the release cloth edge will exceed layer of cloth 20cm left and right;
2), flow-guiding screen is laid: the flow-guiding screen entire body is layed on release cloth, overlaps 1-2cm, the edge is lower than upper end 10-15cm;
3), runner lays,
With needlework, winding pipe is made on flow-guiding screen during laying, lid is put glue-injection base in the winding pipe center, and casing is except bottom centre position is put glue-injection base, and every winding pipe is all put a glue-injection base at position of center line.
2, vacuum bag is laid:
Table 2
1), at the mould port apart from about layer of cloth 10cm, the closed winding pipe of placing of annular uses a small amount of glue spraying to make release cloth wrap up winding pipe; And equidistantly place respectively two threeways of bleeding on mould surrounding winding pipe, then connect extraction pipe to vacuum pump;
2), the mould port cleans out with rag, pastes a circle sealing joint strip at die edge, when vacuum bag is laid, reserves enough areas and makes the whole die cavity of its covering; Vacuum bag edge and sealing joint strip are clinged close, folding line must not occur, when giving a discount because of needs, need fill booklet with sealing joint strip.
Vacuum suction, pressurize:
1), open vacuum pump, the degree of vacuum in mould reaches fixedly the vacuum bag film and a bag film can regulate the time, closes evacuating valve, adjusts the vacuum bag film, makes it without phenomenon unsettled, tension, then opens evacuating valve;
2), after degree of vacuum reaches capacity vacuum 0.1MPa, close evacuating valve, pressurize 20 minutes, degree of vacuum is qualified greater than 0.08MPa side.Otherwise to hunt leak to vacuum system, again carry out the pressurize test, until meet the requirements.
3, vacuum injecting glue:
Table 3
1), gel test: will first carry out gel test according to humiture at that time before injecting glue, to determine curing agent at that time, the addition of accelerator; The interpolation of curing agent should be guaranteed the Gel time 30-40min of lid, the Gel time 60-80min of casing.
2), join glue: according to the result preparation resin of gel test, resin 10kg one joins, and first adds accelerator during preparation, after it stirs, adds curing agent, stirs;
3), injecting glue: the injected rubber hose of intercepting sufficient length, one end is first put in the resin barrel for preparing, the other end is wrapped with two or three layer of sealing joint strip apart from about port 2cm, insert in glue-injection base after twining, and the sealing joint strip sealing that twines with port simultaneously, the insertion sequence of gum-injecting port is from inside outwards, when the resin of first runner surpasses second runner fully, can open second runner, need close first runner when opening the 3rd runner, the like, injected rubber hose only need to keep two injecting glues at the same time.
Notice: in a. injecting glue process, resin will in time be prepared interpolation, remain that the resin in the injecting glue bucket will be more than 1kg;
B. in the injecting glue bucket, resin wanted gentle agitation for a moment every five minutes, prevented curing agent sedimentation in bucket;
C. breakage arranged and leak gas as discovery vacuum bag film in the injecting glue process, in time carrying out shutoff with sealing joint strip.
4, solidify: the required glass of product fully by after resin impregnated, is closed all runners and stops resin by injection in die cavity.Resin subsequently
To begin to heat up, treat its exothermic peak later temperature drop to 40 ℃ of left and right and close vacuum pump, tear the auxiliary material of vacuum.
Nine) demoulding, and carry out surface treatment, mark, finished product is as shown in Figure 1.
