Paub txog Kev Pab Thaum Kev Tsim Khom Qhov Chaw Tshav Kub

Caij rau Qhov Chaw Tshav Kub nyob rau hauv Lub System Framing Aluminum

Txoj kab sib txuas kheej tso rau hauv qab no tsim kev sib tshooj tsis pub kom tuaj ntxig rau hauv lub frame aluminum, uas tuaj yeem pab nce kev siv kho tshuaj ntau dua li 40% hn compared to regular profiles without breaks (according to NFRC data from 2023). Ntau tshaj plaws tsim los ntawm cov khoom siv zoo li polyamide lossis reinforced polymer composites uas muaj cov kab roj fiberglass, cov khoom no yuav pab kom dimin heat transfer thaum twg kis tau tias tsis txhob tshav kub. Kev xaiv tus khoom siv tseem ceeb heev nyob no. Piv txwv li, PA66GF25 muaj kev pab ruaj khov zoo dua thiab muaj R values txog ib puag ncig 0.25 square meters Kelvin per Watt thiab tseem muaj kev ruaj khov zoo tom qhov chaw nyob ib cheem.

Pour and Debridge vs. Crimped and Rolled: Qhov sib txawv tseem ceeb ntawm ob hom

Ob hom kev tsim khoom feem ntau tshaj tiv thaiv thermal break:

• Pour and DeBridge : Lub liquid polymer yog injected rov qab hauv lub aluminum cavities thiab cured, tshwm sim ib qhov seamless insulation uas muaj thermal bridging tsawg dua 30% li lub conventional designs (US DOE 2023). Txawm tias slow dua, txoj cai no txhob kom muaj kev ua haujlwm siab.
• Crimped and Rolled : Lub pre-formed polymer strips yog mechanically locked nyob saum npaug ntawm cov aluminum profiles. Tsav ntev dua rau tsim, tab sis feem ntau siv cov ntaub ntawv tsis nyob ntev li PVC, uas yuav phom siab thaum kawg.

Cov Qhov Noj Nyob Rau Hauv integrated thermal break systems merge both approaches using robotic insertion, achieving production rates exceeding 120 units/hour without compromising performance.

Integrated Thermal Break Technology: Current Trends and Benefits

Novations tam sim no xeej mus rau cov hybrid materials zoo li aerogel-enhanced composites thiab graphene-infused polymers, xa kom muaj kev pab ntau:

Kev kho tshuab co-extruded txo cov ntaub ntawv muaj peev xwm ntxiv rau ib txhais, txhim kho kev sib tshooj rau kev tshahan thiab tswj yeej qhov sib sau ua ke txaus 12 MPa shear strength (ASTM D1002-22).

Thaub qhov chav tsim khoom tag nrho rau kev txhim kho tshwj tsis

Ib qhov kev tsim kho tshuab thermal break feem ntau muaj li khoom ncav cuag:

1. Kev saum ntaub ntawv – PA66GF25 granules saum nyob rau 80°C los ntawm 4–6 teev
2. Kev tsim kho tshuab ntsuas – ±0.1mm qhov loj me me tau ntsuas los ntawm kev tswj hwm kaw
3. Kuaj tshuab roj teeb – Siv tsai laser kom paub meej txog 99.9% nyob rau hauv qhov tseeb
4. Kuaj qhov kualitee – Siv kawg kuab ntawm -40°C mus rau 90°C los tshawb xyuas qhov nyab
5. Ntim – Kaw tais nrog nitrogen kom tsis muaj kab phom
6. Xam cov leej pib – Siv IoT kom paub tag nrho yam uas tau tsim los yog siv

Thaum siv kev soj nqi viscosity nyob ze thiab kho los ntawm AI, tus neeg tsim khoom tau txo cov khoom tsis xav siv los 22% thaum twv tau standard ISO 9001:2015.
