Yuav Ua Li Cas Xaiv Cov Khoom Siv Thermal Break Strips Rau Windows Thiab Qhov Rooj?

Dab tsi yog thermal break strip?
Cov kab thermally break yog ib qho tseem ceeb ntawm cov qhov rais thiab qhov rooj aluminum uas tau rhuav tshem thermal bridge. Thiab qhov tseem ceeb ntawm cov kab thermally break yog thermal insulation.
Cov kab thermally break yog siv dav rau lawv qhov muaj peev xwm thaiv kev kub ceev. Qhov zoo ntawm cov kab thermally break tsis tsuas yog txiav txim siab txog thermal insulation qhov kev cuam tshuam ntawm cov qhov rais thiab cov qhov rooj, tab sis kuj tseem muaj kev cuam tshuam tseem ceeb rau qhov cua siab, dej tsis muaj dej, huab cua tsis muaj huab cua, thiab lwm yam ntawm cov qhov rais thiab cov qhov rooj. Cov kab thermally break kuj txiav txim siab ntau tshaj 50% ntawm qhov kev cuam tshuam insulation ntawm cov qhov rais thiab cov qhov rooj.

Tam sim no, muaj peb yam khoom ntawm thermal so strip ntawm lub khw:
PAB 66
PVC
PU

Ob qho tib si PA66 thermal so strip thiab PVC thermal so strip yog tsim rau kev siv lub tshuab nqus tsev (raws li qhia hauv daim duab 1). PU thermal so strip yog tsim rau Pour & Debridge ua tshuab (raws li qhia hauv daim duab 2).

Niaj hnub no peb tab tom tham txog cov thermal so strips uas tsim nyog rau kev siv lub tshuab nqus tsev. Qhov ntawd yog PA66 thermal so strip thiab PVC thermal so strip.

Qhov sib txawv tseem ceeb ntawm ob qho no yog raws li hauv qab no:
Cov khoom sib txawv
PA66 thermal so strip yog ua los ntawm PA66 thiab 25% iav fiber.
PVC thermally break kab yog ua los ntawm PVC thiab 25% calcium carbonate.

txawvQhov tshwm sim
PA66 thermal so strip muaj qhov ci dua, tsaus xim dub. PA66 strip muaj du thiab tiaj tus thiab nws zoo li zoo li frosted zoo nkauj. Muaj cov cim iav nias los ntawm lub rub tawm ntawm ob sab.
Cov xim ntawm PVC thermal so strip yuav tsum sib dua, feem ntau greyish dub. Piv rau PA sawb, qhov saum npoo ntawm PVC sawb zoo li tsis yog li ntawd. Tej zaum yuav muaj kev xav ntawm qhov pits thaum saib ntawm sab. Tsis muaj cov cim iav ntawm ob sab.

Duab 4 Cov txheej txheem sab ntawm PA66 kab thiab PVC kab

txawvToughness
PA66 thermal so strip tuaj yeem tawg tom qab muab tais rau 1-2 zaug. Yuav muaj lub suab meej thiab nkig thaum tawg. Tom qab tawg, qhov tawg yog huv si thiab tsis deformed. Thiab strips tuaj yeem rov qab los ntawm docking.
PVC thermal so strip yog mos, yooj yim rau khoov, thiab tsis yooj yim rau tawg. Nws yuav tsum tau muab tais rau hauv ib nrab rau ntau tshaj kaum zaug ua ntej tawg. Tom qab tawg, qhov tawg ua dawb, deformed. Cov strips tsis tuaj yeem rov qab los ntawm kev docking.

Duab 6 Cov txuas sib txawv ntawm PA66 kab thiab PVC kab

txawvThermal Deformation Kub
PA66 Thermally Break Kab: txog 240℃
PVC Thermal Break Sawb: nyob ib ncig ntawm 90 ℃

txawvTensile zog
PA66 Thermal Break Strip ≥ 120N/mm
PVC Thermal Break Sawb: nyob ib ncig ntawm 70N / mm

Dyog Flammability
PA66 thermal break strip yuav txuas ntxiv los ntawm qhov hluav taws tom qab tawm ntawm qhov chaw hluav taws, thiab nws tsw zoo li cov plua plav. Tab sis ntxiv cov khoom tiv thaiv hluav taws rau cov khoom raw tuaj yeem ua rau PA66 thermal break strips muaj qhov ua haujlwm ntawm Flame retardant performance.
Cov khoom siv PVC tsis muaj nplaim taws. Thaum nws tawm ntawm qhov hluav taws kub, PVC thermal so strip yuav cia li tua, nrog rau cov pa luam yeeb dub thiab tsis hnov tsw ntawm pungent yas.

Sib txawv Photothermal Sensitivity thiab Aging Resistance
PA66 thermal break strip kuj tseem tuaj yeem khaws nws qhov ruaj khov hauv qhov teeb pom kev zoo. Nws yog durable, tsis yooj yim los ua qhuav.
PVC thermal so strip yog yooj yim los ua nkig ntawm chav tsev kub thiab kub, uas txhais tau hais tias nws yooj yim tawg thiab yooj yim rau kev laus tom qab raug tshav ntuj.

Cov Coefficient Expansion Linear txawv
Cov coefficient expansion linear ntawm PA66 thermal break strip yog (2.3-3.5)*10^-5
Lub linear expansion coefficient ntawm PVC thermal so strip yog 8 * 10^-5
Lub linear expansion coefficient ntawm txhuas profile yog 2.35 * 10^-5
Qhov ze dua ntawm linear expansion coefficient yog, qhov ntau dua uas ob cov ntaub ntawv yuav ua kom synchronized expansion thiab contraction thaum ib puag ncig kub hloov. Yog li txhawm rau ua kom muaj kev ncaj ncees ntawm thermal so strip thiab aluminium profile qauv.

Muab piv rau ob, PA66 thermal so strip muaj zog thermal rwb thaiv tsev, kev ua haujlwm ruaj khov dua, thiab tsis yooj yim deformed.
Thaum xaiv thermal so strips, nws raug nquahu kom xaiv PA66 thermal so strips.
Txoj kev xaiv yog ua raws li cov txheej txheem saum toj no los txiav txim seb qhov tsos zoo li cas, nws yog xim dab tsi, seb nws puas yooj yim tawg, thiab seb puas muaj ntxhiab tsw txawv txawv thaum hlawv.
