Silicone Sealant muStructural Glazing: Chii Chinonyanya Kukosha muGlass Curtain Wall Bonding

Muzvivakwa zvemazuva ano, magirazi eketeni madziro haachisiri sarudzo yerunako-ava chirevo chekugona kweinjiniya. Mafaçadhi eTower, nzvimbo dzekutengeserana, nhandare dzendege, uye{2}}zvivakwa zvakakwirira zvinotsamira pamaitiro ekugadzira glazing kuti zvitaridzike zvakachena, zvisina musono.

Seri kwe "magirazi" ese, zvisinei, pane chinhu chimwe chakakosha chinoshanda chinyararire kumashure:

silicone sealant yekubatana kwemaitiro.

Kune zvikwata zvekutenga uye façade makondirakiti, iyi haisi yegeneric inodyiwa. Chinhu chekuchengetedza-chakakosha. Kana girazi raiswa, chisimbiso chinova chikamu chehamvuropu yekuvaka kwemakumi emakore.

Ndosaka kusarudza silicone sealant yakakodzera yekugadzira glazing kushoma pamutengo-uye zvakawanda nezvenguva refu-yenguva yakareba structural kuvimbika.

1. Chii chekugadzira glazing chinoda kubva kune silicone

Kusiyana nekuisa chisimbiso chekutanga, kupenya kwechimiro hakusi kwekuvhara mvura kana mweya.

Inofanira kubata:

Permanent mutoro kutamisa pakati girazi uye furemu

Kudzvinyirirwa nemhepo uye masimba ekusveta

Thermal kuwedzera uye contraction cycles

Kugara-kwenguva refu UV

Kuvaka kufamba uye vibration

Nemamwe manzwi, chisimbiso hachisi kungozadza mubatanidzwa-zvirikutora chikamu mukuita kwemaitiro.

Ndosaka structural silicone iri muchikamu chakasiyana zvachose kubva kune-chinangwa sealants.

2. Sei silicone sealant inoshandiswa mumaketeni emadziro maitiro

Silicone inoramba iri chinhu chikuru mukupenya kwechimiro nekuda kwezvikonzero zvakati wandei zvakakosha:

(1) Kudzikama kwepamusoro nekugadzikana-kwenguva refu

Girazi nealuminium mafuremu zvinofamba zvakasiyana pasi pekuchinja kwetembiricha. Silicone inogona kutambanudza uye kupora kakawanda pasina deformation zvachose.

(2) Yakanakisa UV kuramba

Madziro emaketeni akazara pachena kune chiedza chezuva. Zvishandiso zvakawanda zvinodzikira nekukurumidza pasi peUV, asi chimiro chesilicone chinochengetedza kutendeseka kwemakumi emakore.

(3) Kunamatira kwakasimba kugirazi nesimbi

Yakagadzirwa zvakanaka silicone bonds zvakanaka ne:

Girazi

Aluminium mafuremu

Masimbi akavharwa

Spacer masisitimu

(4) Tarisiro yehupenyu hurefu hwebasa

Mune façade engineering, dhizaini hupenyu hunowanzo 20-30 makore. Silicone ndechimwe chezvishoma zvigadzirwa zvinogona kuzadzisa izvo zvinodiwa.

3. Structural silicone haisi "kungosimbisa"

Kusanzwisisana kwakajairika mukutenga kurapa kwechimiro chesilicone seyakajairwa weatherproof sealant.

Muchokwadi, structural glazing silicone ndeye:

A load-inonamira system

A yakaedzwa engineering zvinhu

A certified façade chikamu

Inofanirwa kusangana nemaitiro akasimba ekuita akadai se:

Tensile simba zvinodiwa

Movement kugona (± 25% kana kupfuura)

Peel adhesion simba

Kuramba-kwenguva refu

UV uye mamiriro ekunze kuchembera kuramba

Kana imwe yeiyi paramita ikatadza, iyo yese façade system inogona kukanganisika.

---

4. Iwo maviri-layer system mucurtain wall sealing

Mazhinji masisitimu ekupenya anotsamira pambiri-seal approach:

Primary structural chisimbiso (yakakosha mutoro{{0}inotakura bond)

Iyi ndiyo silicone adhesive inosungira girazi kune furemu. Inotakura mutoro wemhepo uye kusagadzikana kwemaitiro.

Secondary weather seal

Iyi denderedzwa inodzivirira kubva pakupinda kwemvura nemhepo asi haitakuri zvimiro zvemuviri.

Matunhu ese ari maviri anofanira kushanda pamwechete, asi ndiwostructural chisimbiso chinotsanangura kuchengetedzwa kwehurongwa.

5. Chii chinokonzera kukanganisa kwekugadzira glazing mumapurojekiti chaiwo

Kana kutadza kwemadziro eketeni kunoitika, haawanzo kurongeka. Kuongorora kwemumunda kunowanzo nongedzera kune dzimwe nyaya dzinodzokororwa:

(1) Zvinhu zvisingaenderani

Haasi ese silicones akagadzirirwa kushandiswa kwemaitiro. Kushandisa weatherproof{{1}grade silicone in structural applications ndeimwe yezvikanganiso zvinowanzoitika-uye zvine ngozi-.

---

(2) Kusagadzirira kwepamusoro

Girazi uye aluminium nzvimbo dzinofanirwa kuve:

Clean

Dry

Husina oiri, huruva, kana machira ekudzivirira

Kunyangwe kusvibiswa kwemicroscopic kunogona kuderedza simba rekunamatira zvakanyanya.

---

(3) Magadzirirwo asina kunaka akabatana

Structural silicone inoda chaiyo geometry:

Yakakodzera bond line ukobvu

Controlled movement allowance

Uniform stress distribution

Kusarurama dhizaini inotungamira kune localized kushushikana kusungirirwa uye pakupedzisira kukundikana.

---

(4) Mamiriro ekurapa asina kunaka

Humidity uye tembiricha zvinokanganisa kukurumidza kurapa uye kuumbwa kwemukati. Kutadza kutonga saiti kunogona kukonzera kusakwana kwekurapa kana kusasimba kwekubatanidza nzvimbo.

6. Acid cure vs neutral cure: nei structural glazing inonyatsorapa

Mune zvimiro zvekushandisa, asidhi yekurapa silicone haina kushandiswa.

Zvikonzero zviri nyore:

Asidhi ne-zvigadzirwa zvinogona kukanganisa simbi

Haina kukodzera kune yakavharwa aluminium masisitimu

Kudzikama-kwenguva refu

Haina certified yemaitiro ekuremedza maapplication

Structural glazing masisitimu anotsamira chete pane:

👉 kwaakarerekera kurapa structural silicone (alkoxy kana oxime masisitimu)

Aya masisitimu anopa:

Kusapora{{0}kuora

Yakagadzikana kunamatira kune girazi uye aluminium

Zvirinani kuita-nguva refu isingachinjiki

Pakutenga, izvi hazvisi{0}}zvinotaurika.

7. Key performance zviratidzo zvikwata zvekutenga zvinofanira kuongorora

Paunenge uchitsvaga chimiro chesilicone kumadziro emaketeni, kuongororwa kwehunyanzvi kunokosha kupfuura mhando kana mutengo.

Zvinokosha parameters zvinosanganisira:

1. Structural certification

Tarisa kutevedzera façade zviyero uye yakasimbiswa structural test report.

2. Kusimba uye kusvuura simba

Aya maitiro anotsanangura kuti iyo silicone inogona sei kubata girazi pasi pemamiriro emhepo.

3. Movement kugona

Zvivakwa zvepamusoro-zvinogara zvichifamba. Chinodiwa chinodikanwa: ± 25% kana kupfuura.

4. UV uye kusagadzikana kwemamiriro ekunze

Zvakakosha kuti-nguva refu ioneke façade pasina kudzikisirwa.

5. Kuenderana ne substrates

Inofanirwa kuita zvinoenderana ne:

Float glass

Girazi rakavharwa

Anodized aluminium

PVDF-mafuremu akavharidzirwa

---

8. Kuita kwemumunda kunonyanya kukosha kupfuura data yerabhoritari

Chimwe chezvinhu zvisingatarisirwi pakutenga zvinhu ndeyechokwadi-nhoroondo yenyika.

Structural glazing haisi iyo inodzorwa lab nharaunda. Zvinosanganisira:

Tembiricha inotenderera kubva kuchando kusvika pakupisa kwakanyanya

Kuchinja kwemhepo

Kwenguva refu-kushushikana kwechimiro

Kuisa musiyano pakati pemapurojekiti

Ndosaka makondirakiti ane ruzivo anowanzo kukoshesa vatengesi vane mareferensi epurojekiti yefaçade pamusoro pezvinotsanangurwa.

---

9. Apo silicone structural glazing inoshandiswa

Maapplication akajairika anosanganisira:

Madziro egirazi-akakwira emaketeni

Façades yekuvaka yekutengeserana

Airport terminals

Shopping mall skylights

Structural glass fins and point{0}fixed systems

Frameless girazi façades

Muzviitiko zvese izvi, silikoni haisarudzike-inoumbwa.

Mhedziso

Silicone sealant mukugadzira glazing haisi chinhu chinotsigira-chikamu chemaitiro echivako.

Kune zvikwata zvekutenga uye mainjiniya efaçade, dambudziko rakakosha harisi kuwanikwa, asi kusarudza magadzirirwo akanyatsogadzirwa, akaedzwa, uye akatenderwa kushandiswa kwemaitiro.

Nekuti kana yangoiswa mucurtain wall system, silicone haichabatiki.

Inova chikamu chehamvuropu-yekuchengetedza yenguva refu.

Uye muinjiniya yefaçade, hapana nzvimbo yekusavimbika-chete maitiro anoramba aripo-nemamiriro ezvinhu enyika, gore negore.
