Muaj ntau ntau hom ntaub ntawv siv rau lub qhov rooj thiab qhov rais ntsaws ruaj ruaj nyob rau hauv lub lag luam, feem ntau yog ua los ntawm PVC, hloov PVC, EPDM, elast seals (xws li TPV, TPE, TPR, SEBS), silicone, thiab lwm yam. Lawv yog siv nyob rau hauv lub qhov rooj ntoo. thiab qhov rais, aluminium alloy qhov rooj qhov rais, yas steel qhov rooj thiab qhov rais, thiab lwm yam architectural hniav qhov rooj thiab qhov rais. Qhov kev ua tau zoo ntawm ntau lub qhov rooj thiab qhov rais seals yog qhov sib txawv, uas ncaj qha txiav txim siab lawv siv tau. Niaj hnub no, tus editor tau nthuav qhia tshwj xeeb ntawm qee cov ntaub ntawv tsim nyog tshaj plaws rau kev siv tsev neeg ntawm cov ntaub ntawv uas nquag siv.
1.1 Kev faib tawm ntawm cov khoom siv sealing
1. Plasticized polyvinyl chloride sealing sawb
Cov khoom siv yog pheej yig thiab yooj yim muaj, nrog rau siab tiv thaiv corrosion, hnav, thiab combustion, nrog rau siab mechanical zog; Txawm li cas los xij, muaj ib qho kev nyiam rau plasticizers nyob rau hauv lub compounding system tsiv teb tsaws, ua rau hardening thiab brittleness nyob rau hauv lub sij hawm, poob ntawm elasticity, tsis zoo aging kuj thiab inferior weatherability thiab qis-kub. Nws feem ntau yog siv rau hauv cov khoom siv xim tsaus. Nws yog qhov tsim nyog rau qee lub sijhawm uas tsis tshua muaj teeb pom kev zoo, qhov kub thiab txias hloov pauv me me thiab huab cua me me.
2. EPDM foob sawb
Kev ua tau zoo heev, ozone tsis kam, siab thiab tsis kub tsis kam, tshuaj lom neeg tsis kam, tsis kam mus rau ntau yam polar solvents, thiab tsis tshua muaj lub ntiajteb txawj nqus. qhov tsis zoo yog tias nws swells zoo heev hauv cov roj ntxhia zoo tib yam thiab cov roj lubricating, thiab feem ntau yog cov khoom siv xim tsaus. Kev khiav hauj lwm kub yog -60 txog 150 degrees Celsius. Vim nws txoj kev ua tau zoo tshaj plaws, nws tau lees paub dav hauv kev lag luam. Nws tuaj yeem siv rau hauv qhov kub thiab txias, txias, thiab muaj zog UV-irradiated thaj chaw nrog rau hauv cov tsev nruab nrab-rau-siab.
3. Thermoplastic Vulcanizate (TPV) Seal Strips
Nws muaj qhov yoog raws thiab elasticity ntawm cov roj hmab, tuaj yeem tsim siv cov txheej txheem ua cov yas, tsis tas yuav vulcanization, thiab nws cov pov tseg tuaj yeem rov ua dua thiab rov siv dua. Nws yog ib yam khoom uas muaj ntau yam khoom, zoo kub tsis kam thiab txias tsis kam, tsis tshua muaj txheeb ze ntom, roj kuj thiab hnyav kuj zoo li chloroprene roj hmab, tab sis tsis zoo nyob rau hauv compression teeb thiab hnav tsis kam. Nws tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam xim, nrog rau kev siv kub ntawm -40 txog 150 degrees Celsius. Nws yog qhov tsim nyog rau qhov chaw txias txias nrog rau cov tsev nruab nrab-rau-siab.
4. Polyurethane roj hmab sealing sawb
Nws muaj elasticity zoo thiab zoo heev hnav tsis kam, zoo roj kuj, ntau yam hardness (Shore A hardness 65-8), superior mechanical zog (tensile zog, elongation ntawm so), zoo heev txias kuj thiab tshuaj tiv thaiv, thiab cov tus nqi ntawm cov khoom siv raw yog siab. Nws yog cov khoom siv rov ua dua tshiab. Nws tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam xim. Kev khiav hauj lwm kub yog -60 txog 80 degrees Celsius. Nws yog qhov tsim nyog thaj chaw uas muaj av qeeg ntau zaus, nyob ze ntawm txoj kev tsheb ciav hlau, lossis hauv cov chaw ua haujlwm nrog cov cranes loj, nrog rau cov cheeb tsam uas muaj zog ultraviolet hluav taws xob.
5. Silicone roj hmab sealing sawb
Nws muaj qhov ua tau zoo ntawm qhov kub thiab txias tsis kam, ozone tsis kam, thiab huab cua tsis kam; nws muaj zoo heev hydrophobicity thiab tsim nyog breathability nws muaj unparalleled rwb thaiv tsev zog; nws tuaj yeem ua tau raws li qib kev huv uas yuav tsum tau ua rau kev nyiam huv ntawm zaub mov thiab tuaj yeem ua tau raws li ntau yam xim. Qhov tsis zoo yog tias nws lub zog txhua yam yog cov khoom siv roj hmab thiab nws tsis yog roj-resistant. Qhov ntsuas kub yog -100 txog 300 degrees Celsius. Nws tuaj yeem siv rau hauv qhov chaw siab, txias, thiab muaj zog ultraviolet hluav taws xob, nrog rau hauv cov tsev nruab nrab-siab-siab.
