INSERTION PROCESS OF THERMAL BREAK ALUMINIUM PROFILES

Aluminium muaj ntau yam khoom zoo heev, nws yog cov khoom siv zoo tshaj plaws rau cov txheej txheem fenestration hauv ntau txoj hauv kev. Tab sis txhuas kuj yog cov khoom siv hluav taws xob kub heev uas yuav hloov pauv huab cua sab nrauv sab nrauv. Yog li ntawd cov neeg tsim thermal so system kom txo tau cov cua sov conduction.

Tam sim no, muaj ob hom ntaub ntawv uas feem ntau siv nyob rau hauv thermal so system:

• Polyurethane Pour & Debridge
• Polyamide thermal so strips

Rau polyurethane pour & debridge system, ib tug channel yog tsim rau hauv cov txhuas profiles thiab sau los ntawm cov kua polyurethane. Tom qab ntawd tshem cov hlau txuas hauv qab ntawm cov channel kom cia cov polyurethane hardened los ua ib qho insulator. (raws li qhia hauv daim duab 1 thiab daim duab 2)

Rau polyamide thermal so strip system, polyamide sawb yog mechanically ntxig ntawm ob aluminium profiles. Polyamide sawb yog lub insulator. (raws li qhia hauv daim duab 3 thiab daim duab 4)

Niaj hnub no, peb tab tom tham txog cov txheej txheem ntxig uas yuav tsum tau ua hauv thermal so aluminium profiles. Vim hais tias ntxiv rau qhov zoo ntawm polyamide sawb nws tus kheej, cov txheej txheem ntawm cov txheej txheem txheej txheem yog ib qho tseem ceeb los txiav txim siab qhov zoo ntawm thermal so aluminium profiles.

Feem ntau hais lus, cov txheej txheem ntxig yog ua tiav los ntawm plaub kauj ruam:
Profile kev lag luam
Sawb insertion
Crimping
Shear zog test

Thawj kauj ruam:ProfileKnulling
Profile knurling yog dov tawm "cov hniav" ntawm ib feem ntawm cov txhuas profile uas yuav tsum tau ntxig polyamide strips.(raws li qhia hauv daim duab 5 thiab daim duab 6)

Lub hom phiaj ntawm knurling yog txhawm rau ua kom cov roughness ntawm qhov profile, yog li nws tuaj yeem txhim kho lub zog shear zog ntawm kev sib xyaw aluminium profile. Profile knurling yog ib txheej txheem tseem ceeb heev.

• Kauj ruam ob: staug kevKuvlus hais

Cov ntaub qhwv polyamide yog muab tso rau hauv lub qaum thiab qis aluminium notches los ntawm kev qhia rail ntawm lub strip insertion tshuab, kom lawv tuaj yeem txuas tau ua ke.(raws li qhia hauv daim duab 7) Cov txheej txheem ntxig ntawm qee cov khoom siv sib xyaw hauv lub tshuab knurling, uas yog, polyamide strip yog ntxig rau hauv cov txhuas profile hauv cov txheej txheem ntawm qhov profile knurling. Tom qab muab tso rau, lub polyamide strip thiab aluminium profiles tsis nruj nreem kaw. Lawv xoob. Cov strips thiab aluminium profiles tuaj yeem txav nrog ib leeg. 

Rau cov txhuas profile uas ob qhov chaw nruab nrab ntawm qhov deb tsawg dua 10mm (raws li qhia hauv daim duab 8), nws yog qhov nyuaj rau ntxig cov strips polyamide los ntawm lub tshuab strip inserting. Nyob rau hauv cov ntaub ntawv no, peb tuaj yeem tsuas ntxig polyamide strips los ntawm phau ntawv.

• Kauj ruam peb:crimping

Crimping yog nias ntawm aluminium profiles thiab thermal so strips siv peb txheej ntawm lub log nyuaj. Peb txheej ntawm dov log yog siv rau preloading, compressing, thiab kho raws. (raws li qhia hauv daim duab 9 thiab 10)

• Kauj ruam plaub:shnovszogTyog

Cov kauj ruam xeem yog qhov yooj yim heev. Siv zog nce mus rau qhov profile longitudinally kom txog thaum misalignment tshwm sim ntawm aluminium profile thiab thermal so strip.(raws li qhia hauv daim duab 11 thiab daim duab 12)  

Tsis tas li ntawd, qhov kev sim no tsis yog kev sim ib zaug. Peb yuav tsum sim 10 cov qauv ntawm 100mm. Thaum lub sij hawm tus txheej txheem, nws yuav tsum tau muab sau tseg hais tias lub Upper thiab qis clamping blocks tsis tau pinched rau thermal so strips. Lub hom phiaj los ntsuas lub zog shear yog sim lub zog ntawm kev sib xyaw ntawm thermal so strips thiab aluminium profiles. Suav teb tus txheej txheem teev tseg tias tus yam ntxwv tus nqi ntawm longitudinal shear zog ntawm thermal so aluminium profile yuav tsum ntau dua 24N / hli.
