TPE sealant qhov kev ua tau zoo thiab cov yeeb yam

Nrog rau kev kawm txog science thiab technology hauv peb lub teb chaws thiab kev lag luam ntawm kev lag luam, TPE cov ntaub ntawv raw tau hloov tau cov khoom lag luam thiab maj mam siv rau ntawm cov tsheb, tsheb nqaj hlau, xov, qhov rais thiab qhov rooj. Kev ua tiav ultra-high cost ntawm TPE sealant tau los ua tus yuam sij hloov cov roj hmab strips EPDM, PVC, silicone, thiab lwm yam.) Cov khoom zoo tshaj plaws.

Thiaj li ua raws li lub khw nyiam TPE qhov rooj thiab lub qhov ncauj foob nyob rau hauv qhov kawg yog dab tsi? Feem ntau TPE sealant qhov kev ua haujlwm loj thiab nta yog raws li hauv qab no:

1, Kev kub siab thiab tsis kub cev: Cov kub ua haujlwm muaj peev xwm ncav cuag -50ºC rau + 110ºC, thiab qhov hloov ntawm hardness tsis tshaj 4HA ntawm qhov kub ntawm -20ºC txog + 40º, uas zoo dua cov khoom siv PVC thiab EPDM sealing strip.

2, lub thermal conductivity ntawm tsawg dua 0.2W / (m • K), yog cov khoom siv thermal thaiv los txhim kho cov khoom cua sov ntawm qhov rais thiab qhov rooj kom txo tau kev siv zog.

3, zoo resilience, siab dua lub zog: nyob rau hauv tej yam kev mob ntawm 30% compression, 70 ℃ × 24h, cov txheej txheem compression 22%, lub qhov muag tawm lub siab yog 50 KN / M nyob rau hauv qhov kev xeem ntawm ASTM D624;

4, kev ua tau zoo heev: Raws qhov profile xim tshwj xeeb txhua hom xim kab xev, dawb ntaub nplaum, daim kab xev, lwm yam zoo li, xim tsis muaj xim, ploj, zoo nkauj khov kho, txhawm rau txhim kho cov qhov rooj thiab qhov rais.

5, kev siv vuam tshuab: vuam welding yuav fundamentally daws qhov teeb meem ntawm unsmooth kaum foob, kua nplaum tawg thiab lwm yam teeb meem, vuam txheej txheem yog yooj yim, high efficiency, siab vuam zog, yooj yim installation tom qab welding, tab sis kuj txuag lub ces kaum, kua nplaum thiab lwm cov nqi, Yog tau siv los ntawm ntau thiab ntau dua qhov rooj thiab qhov chaw lag luam.

6, non-toxic, environmentally friendly, non-polluting: Tsis muaj carcinogens xws li nitrite, tsis muaj roj, cov ntxhiab tsw, tsis muaj teebmeem rau tib neeg lub cev, ib puag ncig, yog cov khoom ntsuab. Khoom los ntawm SGS ntawv pov thawj, nyob rau hauv txoj kab nrog lub EU ROHS kev tswj, tshwj xeeb tshaj yog rau cov tuam txhab ua lag luam xa tawm.

7, Cov khoom siv uas tsis tshua muaj siab: tsis muaj cov hmoov kiav txhab thiab lwm yam muab tub lim hauv cov txheej txheem. Qhov ceev ntawm qhov khoom yog 0.93-0.98, uas tsuas yog li ntawm 67% ntawm cov ntaub ntawv EPDM sealing. Lub qhov ceeb thawj qhov hnyav ntawm qhov hnyav nplaum yog 1.3-1.4 npaug ntawm EPDM.

8, kev tiv thaiv kev laus muaj kev zoo: lub neej qub tsis tsawg tshaj 20 xyoo. Nyob ntawm UV, kua qaub, ua rau huab cua, ua pa, muaj kab mob zoo. Yuav tsis tshwm ntsej muag, qhov nchuav ntawm cov roj, ua rau kom qhov teeb meem loj, ntev mus xyuas kom muaj kev sib tw ntawm qhov rooj thiab qhov rais.

9, ruaj ntseg ua tau zoo: Lub Teb Chaws Kev Tshawb Fawb Ntawm Lub Tsev Kawm Ntawv (cov sib tw ua tiav) cov khoom tsim nyog uas tsis muaj nplua nuj, qhov rai txheej txhaws ntawm cov xim txheej (dej-xim, xim roj) yuav tsis muaj kab mob, daj, Cov xim dub, txhim kho qhov rooj ntawm qhov rooj thiab qhov rais. Kev sib haum xeeb nrog cov qauv ntawm cov yas, UV lub teeb irradiation 21 hnub tom qab kev ua haujlwm nplaum ua tsis muaj dab tsi, nyob rau hauv txoj kab nrog (lub qhov rooj thiab qhov rais nrog kev sealant) GB16776 cov cai uas tsim nyog.

10, qhov khoom yuav siv tau tom qab ua dua qub, tsim kom txuag thiab txuag hluav taws xob, daws cov qhov rais thiab cov lag luam kev lag luam vim cov kev sib tw lossis tsim teeb meem los ntawm kev txhawj xeeb.

Qhov no qhia tau hais tias kev xaiv ntawm kev ua tau zoo ntawm lub sealing strip tseem ceeb tshwj xeeb, TPE qhov rooj thiab lub khoob qhov rais muaj txhua yam zoo tsis txawv txav yog qhov tseem ceeb tsim nyog los ntawm kev ua lag luam, TPE qhov rooj thiab qhov khoob qhov rais yuav yog qhov kev xaiv thawj- xaus qhov rooj thiab qhov rais.
