Xov xwm

Sealing strips yog ib qho tseem ceeb tshaj plaws ntawm qhov rooj thiab qhov rais accessories. Lawv tsuas yog siv rau hauv thav duab sashes, thav duab iav thiab lwm qhov chaw. Lawv ua lub luag haujlwm ntawm sealing, waterproofing, suab rwb thaiv tsev, kev poob siab, thiab kev txuag hluav taws xob. Lawv yuav tsum muaj lub zog tensile zoo, elasticity, kub tsis kam thiab aging kuj.

Lub sealing strips thiab profiles yog ua ke kom ua tiav qhov yuav tsum tau sealing kev ua tau zoo, uas yog cuam tshuam los ntawm cov khoom tseem ceeb, installation txoj kev, compression ua hauj lwm ntau, compression quab yuam thiab cross-sectional duab ntawm lub strips.
Sealing strips tuaj yeem muab faib ua cov khoom siv ib leeg thiab cov khoom sib xyaw ua ke raws li cov khoom siv.

Cov khoom siv ib leeg muaj xws li EPDM sealing strips, silicone roj hmab (MVQ) sealing strips, thermoplastic vulcanized strips (TPV), thiab plasticized polyvinyl chloride strips (PVC). Cov khoom siv sib xyaw ua ke feem ntau suav nrog cov xaim strips, cov tshuaj tsuag saum npoo av, cov khoom muag muag thiab tawv tawv, cov ntaub txhuam hniav sib txuas, cov ntaub qhwv dej-expandable, thiab coated strips.

Cov xwm txheej uas siv tau ntawm ntau hom kev siv cov sealing strips muaj nyob rau hauv cov lus hauv qab no.

EPDM sealing strips muaj cov yam ntxwv zoo ntawm lub cev (lub zog tensile, elongation ntawm kev tawg, thiab compression mus tas li deformation), huab cua tsis kam, siab thiab kub tsis kam, tiv thaiv corrosion, thiab kev ua haujlwm zoo heev. Tam sim no lawv tau siv dav hauv thaj chaw ntawm lub qhov rooj thiab qhov rais.
Qhov pom zoo siv qhov kub thiab txias ntawm cov khoom sib khi: EPDM cov khoom yog -60 ℃ ~ 150 ℃, MVQ cov khoom yog -60 ℃ ~ 300 ℃, TPV cov khoom yog -40 ℃ ~ 150 ℃, thiab cov khoom siv PVC yog -25 ℃ ~ 70 ℃ .
Sealing strips tuaj yeem muab faib ua hom xovxwm, hom nkag, thiab hom nplaum raws li txoj kev teeb tsa. Lawv tuaj yeem muab faib ua thav duab-sash sealing strips, thav duab-iav sealing strips, thiab nruab nrab sealing strips raws li qhov chaw teeb tsa ntawm lub qhov rooj thiab qhov rais.
Lub thav duab-sash node ntawm ib tug tawg choj aluminium alloy qhov rooj thiab qhov rais yog qhia nyob rau hauv daim duab hauv qab no.

Tus ntoo khaub lig-sectional duab ntawm lub thav duab-sash sealing sawb yuav tsum tau xaiv raws li semi-enclosed los yog kaw raws li qhov xav tau. Thaum qhov tsim nyog tsim muaj ntau yam kev ua haujlwm loj lossis kev ua haujlwm siab sealing, yuav tsum xaiv cov qauv ib nrab.

Txoj kev teeb tsa ntawm lub sealing sawb nruab nrab ntawm lub thav duab thiab lub sash yuav tsum yog ib tug nias-haum installation. Qhov loj tsim ntawm lub installation ib feem ntawm lub sawb yuav tsum xyuas kom meej tias nws tsis poob tawm thiab fits nruj nreem nrog lub profile zawj.
Lub sealing strip ntawm tus ncej thiab lub sash kuj tseem hu ua lub ntsiab sealing sawb los yog isobaric sealing sawb. Nws plays lub luag hauj lwm ntawm thaiv cov cua convection thiab tshav kub hluav taws xob nyob rau hauv qhov profile. Nws yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev sib khi thiab qhib thiab kaw quab yuam ntawm lub qhov rooj thiab qhov rais.
Qhov chaw teeb tsa qhov loj me ntawm cov hlua khi ntawm cov ncej thiab cov iav tau teev tseg hauv JGJ 113-2015 "Technical Code for Application of Architectural Glass", saib cov lus hauv qab no.

Ntawm lawv, qhov ntev ntawm a, b, thiab c yog qhia hauv daim duab hauv qab no.

Feem ntau cov duab sib dhos ntawm cov hlua khi ntawm lub thav duab thiab cov iav tau pom nyob rau hauv daim duab hauv qab no, thiab cov txheej txheem nias-haum installation feem ntau tau txais yuav.

Hais txog kev sib khi ntawm lub thav duab thiab lub khob, muaj lwm lo lus nug tsim nyog los tham txog, uas yog, nws puas zoo dua los siv cov hlua khi los yog cov khoom sib khi ntawm cov ncej thiab cov iav?
Tam sim no, feem ntau lub qhov rooj thiab qhov rais system tuam txhab lag luam hauv tsev thiab txawv teb chaws siv strips ua thawj qhov kev xaiv rau thav duab iav sealing. Qhov no yog vim hais tias cov roj hmab sawb yog cov khoom lag luam, qhov kev txhim kho zoo yog tswj tau ntau dua, thiab nws yooj yim los hloov.
Hais txog kev ua haujlwm ntawm kev thov cov sealant, txawm hais tias JGJ 113-2015 "Technical Code for Application of Building Glass" muab cov kev cai rau pem hauv ntej thiab nram qab clearances, uas yog sib npaug rau kev pom zoo rau txoj kev no, nws tseem tsis tau pom zoo kom ua li ntawd rau ntawm qhov chaw rau hauv qab no. yog vim li cas:
Qhov zoo ntawm kev thov sealant rau ntawm qhov chaw yog uncontrolled, tshwj xeeb tshaj yog qhov tob ntawm kev thov sealant.
T/CECS 581-2019 "Technical Code for Application of Building Joint Sealant" muab cov ntaub ntawv yooj yim thiab cov qauv ntawm kev sib khi, saib cov lus hauv qab no.

Nws tuaj yeem pom tau tias cov kev ntsuas sib xws yuav tsum tau coj los tswj kev tsim kho kom zoo rau kev sib khi ntawm pob qij txha thiab cov pob qij txha.
Piv txwv li, sab nraud sealing sib koom ua ke ntawm cov khoom siv zais zais iav kab hlau rhuav phab ntsa yog lub pob tw sealing sib koom ua ke, thiab kev tsim kho zoo yog tswj los ntawm tus pas nrig ua npuas ncauj. Cov iav thiab cov thav duab txuas yog sib txuas los ntawm ob sab ntawv nplaum los tswj qhov dav thiab tuab ntawm cov qauv nplaum, raws li qhia hauv daim duab hauv qab no.

Cov profiles ntawm kev teeb tsa ntawm aluminium alloy qhov rais thiab yas qhov rais iav yog tag nrho cov nyias-walled profiles - iav beading, sab nraum zoov profile caj npab, thiab lwm yam., thiab tsis muaj tej yam kev mob los tswj qhov dav thiab thickness ntawm lub sealant.
Tsis tas li ntawd, kev siv cov sealant sab nraum zoov tom qab txhim kho lub iav yog qhov txaus ntshai heev. Feem ntau ntawm lub qhov rooj thiab qhov rais installation yog ua tiav nyob rau hauv tsev, thaum lub sealant txheej yuav tsum tau siv rau sab nraum zoov. Nws yog qhov txaus ntshai thaum tsis muaj kev ua haujlwm sab nraum zoov xws li scaffolding, dai pob tawb, thiab cov tsheb loj, tshwj xeeb tshaj yog thaum cov iav panels loj.
Lwm qhov teeb meem tshwm sim yog tias ntau lub qhov rooj thiab lub qhov rais nyob sab Europe tsis muaj sab nraum zoov sab nrauv thiab sash sealing strips, raws li qhia hauv daim duab hauv qab no

Qhov kev tsim no tsis yog txiav cov ces kaum tab sis rau kev txiav txim siab ntawm cov dej.
Qhov rooj thiab qhov rais yuav muaj qhov dej ntws tawm ntawm cov khoom siv kab rov tav lossis kab rov tav nruab nrab stile cov khoom nyob rau hauv qab ntawm txhua qhov kev faib (suav nrog cov seem ruaj khov thiab qhib partitions) kom cov dej nkag rau hauv lub qhov rooj thiab qhov rais tuaj yeem ntws mus rau sab nraud.

Yog hais tias lub sab nraum zoov sab nrauv thiab kiv cua sealing sawb raug ntsia, nws yuav tsim ib qho chaw kaw nrog nruab nrab sealing sawb, uas tsis haum rau isobaric kua.
Hais txog cov kua dej isobaric, koj tuaj yeem ua ib qho kev sim me me: sau lub raj mis dej ntxhia nrog dej, ua rau qee qhov me me hauv lub raj mis, thiab tig lub raj mis rov qab, nws nyuaj rau cov dej ntws tawm ntawm cov qhov me me, tom qab ntawd peb kuj ua qee qhov me me nyob rau hauv qab ntawm lub raj mis, thiab cov dej tuaj yeem yooj yim ntws tawm los ntawm qhov me me hauv lub raj mis cap.
Qhov no kuj yog lub hauv paus ntsiab lus ntawm isobaric kua ntawm lub qhov rooj thiab qhov rais.
Okay, cia peb ua cov ntsiab lus
Sealing strips yog ib qho tseem ceeb tshaj plaws ntawm lub qhov rooj thiab qhov rais accessories, feem ntau yog siv nyob rau hauv thav duab kiv cua, thav duab iav thiab lwm yam, ua si lub luag hauj lwm ntawm sealing, waterproofing, suab rwb thaiv tsev, poob siab absorber, tshav kub preservation, thiab lwm yam, thiab yuav tsum muaj. zoo tensile zog, elasticity, kub tsis kam thiab aging kuj.
Sealing strips tuaj yeem muab faib ua cov khoom siv ib leeg thiab cov khoom sib xyaw ua ke raws li cov khoom siv. Tam sim no, feem ntau siv sealing strips nyob rau hauv lub tshav pob ntawm lub qhov rooj thiab qhov rais muaj xws li EPDM sealing strips, silicone roj hmab (MVQ) sealing strips, thermoplastic vulcanized strips (TPV), plasticized polyvinyl chloride strips (PVC), thiab lwm yam.
Sealing strips tuaj yeem muab faib ua hom xovxwm, hom nkag, thiab hom nplaum raws li txoj kev teeb tsa. Raws li qhov chaw teeb tsa ntawm lub qhov rooj thiab qhov rais, lawv tuaj yeem muab faib ua thav duab-sash sealing strips, ncej-iav sealing strips, thiab nruab nrab sealing strips.
Puas yog nws zoo dua los siv cov hlua khi los yog cov khoom sib khi ntawm cov thav ntawv thiab cov iav? Nyob rau hauv cov nqe lus ntawm kev tsim kho kom zoo controllability thiab nyob rau hauv-site tsim kev ruaj ntseg, tus sau pom zoo kom siv sealing strips es tsis txhob ntawm qhov chaw sealants.
