Abstract
The invention discloses a detection method of water absorption expansion rate of assembled floors, comprising the following steps: 1) assembling four floors wherein the middle two floors are arranged in vertical line shape and another two floors are arranged at the two horizontal sides of the two middle floors, the four floors are in the shape of a Chinese character 'zhong'; 2)respectively making five bench marks respectively in the middle point of the assembling point of the middle two floors, respectively arranged at the upper and lower 1/4 floor-length position at the horizontal sides of the two middle floors and measuring the floor thickness h<SUB>1</SUB> of the five mark points; 3) covering the five bench marks by a water absorption sponge for two hours and measuring the floor thickness h<SUB>1</SUB> of the five mark points h<SUB>2</SUB>, and then calculating the floor thickness water absorption relative expansion degree, if one bench point is larger or equal to 3%, the floor of the batch is not qualified. The detection method simulates the water absorption expansion process of the composite floor to constitute the calculation method capable of more practically characterizing the relative water absorption expansion degree of the finished composite floor and the qualification criterion standard.
Description
Technical field
The present invention relates to the detection method of a kind of floor expansivity, relate in particular to the detection method of the composite floor board splicing place expansion rate of water absorption after a kind of assembly unit, belong to the building decoration technology field.
Background technology
Composite floor board is with its high emulation; durable in use; advantage such as good and cheap obtains application more and more widely; during the composite floor board base material mainly adopts; high density fiberboard; because in; there is the space in the high-density fiber intralamellar part; though the balance layer of the bottom surface of composite floor board and the wearing layer of end face had all been done water-proofing treatment; the tenon and the groove of snap close have also applied water barrier around it; but because snap close does not coat layer protective layer; cause moisture to penetrate in the base material from the snap close of the splicing of composite floor board easily; cause the dilatational strain of floor edge; make the edge, floor swell; the center remains unchanged substantially; form the dish distortion, had a strong impact on the quality on floor and attractive in appearance.
The detection method of existing composite floor board expansion rate of water absorption is according to national standard " impregnated-paper laminated wood floor " regulation (GB/T18102-2007), extract 3 finished product floors in≤1000 finished product floors, two of the floor test specimens of preparation 50mm * 150mm, it is immersed in 20 ℃ of water 24 hours, by measuring the expansion rate of water absorption at test specimen edge, if ≯ 18%, judge that then this batch floor is qualified.In actual detected, some second-rate composite floor board test specimen imbibition index meets the regulation of national standard, but when reality is used, the imbibition process of composite floor board is seldom such just like what stipulate in the standard, the floor is immersed in the water for a long time, but was using wet mop to mop floor, or because of carelessness water is sprinkled in time do not dry water behind the floor, this moment, the edge of composite floor board will perk, had a strong impact on the outward appearance of composite floor board.Obviously, when the detection method of the expansion rate of water absorption of existing composite floor board can not reflect actual use fully, the composite floor board imbibition process after the special assembly unit.
Summary of the invention
In order to reflect composite floor board imbibition process more realistically, characterize the relative expansion rate of water absorption of the composite floor board test specimen after the assembly unit more practically, the present invention proposes the detection method of floor-board water absorption expansivity after a kind of assembly unit, adopt this method can simulation assembling after the dish distortion of the floor edge that caused of the splicing edge suction on floor, and propose to judge the whether qualified regulation of composite floor board expansion rate of water absorption.
The present invention is achieved by the following technical programs:
1, a kind of detection method of assembled floor-board water absorption expansivity may further comprise the steps:
1), on the finished product detection line of floor, according to four finished product floors of extraction in per 2 hours, with four finished product floors according to the vertical word order of middle two floors, the mode of two floor both lateral sides in the middle of other two floors are assembled in respectively, four finished product floors are " in " be assembled into one font;
2), at the mid point of middle two floor splicings place, splice in long position, each 1/4 monolithic floor up and down of middle two floor both lateral sides splicings place respectively, amount to five places and make five gauge points respectively, measure the floor thickness h of described five gauge points
1, and note down;
3), the sponge that will suction water covers on 5 gauge points on institute's assembled floor-board;
4) moisture sponge covered after two hours, measured the thickness h of 5 gauge points once more
2, and note down;
5), after the assembly unit plate thickness suction relative expansion rate computing method as shown in the formula:
In the formula: D---water absorbing floor thickness relative expansion rate %
h
1The thickness mm of test specimen before----immersion
h
2The thickness mm of----immersion back test specimen
6) criterion that whether qualified assembled floor-board suction relative expansion rate is is as follows:
Calculate five thickness relative expansion rate D after the gauge point suction,, judge that then this batch floor is defective if having at one o'clock more than or equal to 3%.
Purpose of the present invention can also further realize by following technical measures:
The detection method of aforesaid assembled floor-board water absorption expansivity, wherein said be assembled in respectively in the middle of the starting point and the terminal point on floor of two floor both lateral sides, be positioned on two point midways up and down of described vertical word order two floors.
The detection method of aforesaid assembled floor-board water absorption expansivity, the temperature that wherein said sponge sucks water remains on 25～29 ℃.
The present invention has reflected the composite floor board imbibition process after the assembly unit truly, the present invention is immersed in original measurement test specimen the method for measuring the imbibition of floor edge thickness in 20 ℃ of water after 24 hours, change the method for four finished product floor edge imbibition thickness after the more realistic measurement assembly unit into, after moisture sponge covers two hours, the ground plate thickness after the imbibition of five gauge points of measurement splicing place.The present invention has simulated the composite floor board imbibition process after the assembly unit, has formulated and has characterized the computing method of the relative expansion rate of water absorption of test specimen and whether qualified criterion more practically, has improved the work efficiency that the composite floor board imbibition after the assembly unit detects.
Advantage of the present invention and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
