Description
Oppfinnelsen vedrører et oppskummet isolasjonsskall med lukkede porer og beregnet for rørisolasjon i et temperaturområde mellom -160°C og +115°C, av den type som benyttes til isolasjon for varmtvanns- og kaldtvannsledninger. The invention relates to a foamed insulation shell with closed pores and intended for pipe insulation in a temperature range between -160°C and +115°C, of the type used for insulation for hot water and cold water lines.
Hovedhensikten med slike isolasjonsskall er å oppnå en forut-bestemt varmeisolasjon uavhengig av monteringspersonalets yt-else og derved på stedet å oppnå kortest mulig monteringstid. Til løsning av denne oppgave ble det på materialsiden innført oppskummede kunststoffer. Av disse er de oppskummede materialer med lukkede porer anvendbare, også for kalde rørledninger, pga. sin vanndampugjennomtrengelighet. The main purpose of such insulation shells is to achieve a predetermined thermal insulation regardless of the performance of the assembly staff and thereby achieve the shortest possible assembly time on site. To solve this task, foamed plastics were introduced on the material side. Of these, the foamed materials with closed pores are usable, also for cold pipelines, because its water vapor permeability.
De er derved betydelig mer mangesidig anvendbare enn oppskummede kunststoffer med åpne porer. Forutsetningen for en jevn varmeisolering er derved imidlertid at det til å begynne med åpne isolasjonsskall under monteringen lukkes damptett. Vanlig-vis forsøker man å oppnå dette ved at støtflatene til isolasjons-skallene sammenklebes butt-i-butt (se bl.a. Grunzweig und Hartmann: "Porofin Isolierschalen")• Herved er det imidlertid ufordelaktig at en dårlig gjennomført sammenklebing kan føre til kondensvanndannelse i isolasjonsskallet, noe som påvirker varmeisolasjonen, og at det ekstra arbeidstrinn, nemlig sammen-klebning, fører til en betydelig reduksjon av timeytelsen ved monteringen. They are therefore considerably more versatile than foamed plastics with open pores. However, the prerequisite for uniform thermal insulation is that, initially, open insulation shells are closed vapour-tight during assembly. This is usually attempted to be achieved by butt-to-butt bonding of the contact surfaces of the insulating shells (see e.g. Grunzweig und Hartmann: "Porofin Isolierschalen") formation of condensation water in the insulation shell, which affects the thermal insulation, and that the extra work step, namely gluing, leads to a significant reduction of the hourly performance during installation.
Ved en annen løsning blir det monterte isolasjonsskall omgitt In another solution, the installed insulation shell is surrounded
av en dampugjennomtrengelig kunststoffbane som lukkes mekanisk. Til dette formål er det på støtkantene til kunststoffbanene påsveiset lister som hakes inn i hverandre. Ufordelaktig er herved den ufullstendige dampavtetning. Monteringen er dess-uten vanskeliggjort pga. de labile forhold for isolasjonsskallet og den løse omhylling. of a steam permeable plastic web that closes mechanically. For this purpose, strips are welded onto the butt edges of the plastic tracks, which hook into each other. In this case, the incomplete vapor sealing is disadvantageous. The installation is moreover made difficult due to the labile conditions for the insulation shell and the loose sheathing.
Den oppgave som ligger til grunn for foreliggende oppfinnelse The task that forms the basis of the present invention
er å tilveiebringe et isolasjonsskall med lukkede porer som på is to provide an insulating shell with closed pores as on
den enklest mulige måte og uten verktøy kan monteres absolutt gasstett. in the simplest possible way and without tools can be installed absolutely gas-tight.
Denne oppgave blir løst ifølge oppfinnelsen ved at isolasjonsskallet består av et på i og for seg kjent måte med en lengdesliss forsynt rør av oppskummet polyolefin med lukkede porer, hvilket rør ved hjelp av langs slissen påsveiset i og for seg kjent glidelukning kan lukkes gasstett og igjen åpnes, idet glidelukningen består av flere i hverandre gripende tetningslepper. This task is solved according to the invention in that the insulation shell consists in a manner known per se with a tube of foamed polyolefin with closed pores fitted with a longitudinal slit, which tube can be closed gas-tight and closed again with the help of a sliding closure welded on along the slit is opened, as the sliding closure consists of several interlocking sealing lips.
Ifølge en fordelaktig utførelse for oppfinnelsen kan det som oppskummet polyolefin benyttes et nettdannet polyetylenskum. According to an advantageous embodiment for the invention, a networked polyethylene foam can be used as foamed polyolefin.
De med oppfinnelsen oppnådde fordeler består fremfor alt deri at det nye isolasjonsskall ved hjelp av en glidelukning som består av flere i hverandre gripende tetningslepper på enkel måte kan lukkes hermetisk og at skallet kan benyttes i et temperaturområde mellom -160°C og +115°C. Hertil kommer at de an-vendte, med lukkede porer benyttede polyolefinskum har myk-elastiske egenskaper og derfor på enkleste måte kan legges rundt vilkårlige rørbøyer og glidelåsen kan lukkes ved enkel manuell betjening. I motsetning til duroplastiske skumstoffer kan det nye isoleringsskall formes spenningsfritt <p>g tilpasses til vilkårlige tverrsnittsendringer, uten at det er nødt til å foreta innskjæringer i skallet. The advantages achieved with the invention consist above all in that the new insulation shell can be easily closed hermetically by means of a sliding closure consisting of several interlocking sealing lips and that the shell can be used in a temperature range between -160°C and +115°C . In addition, the closed-pore polyolefin foams used have soft-elastic properties and can therefore be placed around arbitrary pipe bends in the simplest way and the zipper can be closed by simple manual operation. In contrast to duroplastic foams, the new insulating shell can be shaped tension-free <p>and adapted to arbitrary cross-sectional changes, without having to make incisions in the shell.
Innenfor rammen av oppfinnelsen består en foretrukken utfør-elsesform i at glidelukningen er utformet som et direkte på isolasjonsskallet ekstrudert element, noe som har en særlig gunstig innvirkning når det dreier seg om en kontinuerlig isoleringsskall-fremstilling. Sammenlignet med en påsveiset glidelukning oppnår man den fordelen at man får en vesentlig homo-gen overgang mellom skumstoffet og den kompakte glidelukning. Rørstrengen kan eventuelt gis kjennetegn, derved at glidelukningen utføres i farger. Within the framework of the invention, a preferred embodiment consists in the sliding closure being designed as an element extruded directly onto the insulation shell, which has a particularly favorable effect when it concerns a continuous insulation shell production. Compared to a welded-on sliding closure, the advantage is that you get a substantially homogeneous transition between the foam material and the compact sliding closure. The pipe string can optionally be given a characteristic, whereby the sliding closure is carried out in colours.
