Kakovost zlepljenosti med različnimi materiali poda počitniške prikolice : diplomsko delo - visokošolski strokovni študij

Bohte, Aleš (author), Šernek, Milan (mentor), Medved, Sergej (reviewer)

Pri ogrevanju počitniških prikolic se v zadnjem času pogosteje uporablja toplovodno talno ogrevanje. Zaradi visoke cene aluminijaste pločevine, ki se vgrajuje v pod omenjenih izdelkov, smo raziskovali kakovost zlepljenosti med na novo uporabljeno pločevino in ostalimi materiali. Izdelali smo kompozit, ki je bil po strukturi enak podu počitniške prikolice. Sestavljen je bil iz 2 topolovih vezanih plošč, ekstrudiranega polistirena (Styrofoamr XPS), aluminijaste pločevine in poliuretanskega lepila (Icemar r 145/12) kot veznega člena. Preizkušance dimenzij 50 mm x 50 mm smo testirali na trgalnem stroju Zwick Z100 po standardu SIST EN 319:1996. Proučevali smo razslojno trdnost in delež loma po površini alu pločevine. Ugotovili smo, da je najprimerneje uporabiti neperforirano alu pločevino z nanesenim prajmerjem, pri čemer je ni treba dodatno navlaževati z vodno meglo. Nova uporabljena alu pločevina je cenovno ugodnejša od obstoječe.

• Title: Bonding quality of different materials used for caravan flooring : graduation thesis - higher professional studies

Abstract

When heating the floors of caravans, it is customary to use the water heating system nowadays. Due to the high price of aluminium metal sheets, in-built in the produce mentioned, we researched the quality of gluing between the used metal sheet and the other material. A composite, which is similar to the floors of the caravans in its structure, has been made. It was composed of 2 poplar plywoods, extruded polystyrene (Styrofoamr XPS), aluminium metal sheet and polyurethane adhesive (Icemar r 145/12) as a bonding link. The test pieces of 50 mm x 50 mm were tested on the tearing machine Zwick Z100 according to standard SIST EN 319:1996. The bond strength and percentage of the split of aluminium sheet surface was thoroughly studied. It has been concluded that it is most appropriate to use the unperforated aluminium sheet with the applied primer, hereby it is not necessary to additionally moisten it with water mist. Such new aluminium sheet is more reasonably priced if compared to the exisitng one.
