Silicone Sealant muIGU Sekondari Chisimbiso: Chii Chinonyatso sarudza Yakareba-Term Insulating Glass Performance
Jul 02, 2026
Siya meseji
Mukugadzira insulating glass unit (IGU), kunyanya kutarisisa kunowanzoiswa pamhando yegirazi, spacer system, kana michina yekugadzira. Asi mukushanda kwenguva refu-kwenguva refu, pane chimwe chikamu chinotarisa chinyararire kuti IGU ichagara makore mashanu kana makumi maviri nemashanu:
iyo yechipiri silicone sealant.
Ichi chisimbiso chechipiri hachioneki muchigadzirwa chekupedzisira. Kana iyo unit yaiswa, hapana mushandisi wekupedzisira anozoona zvakare. Asi kana zvikasabudirira, zvinozoitika zvinokurumidza-kupengereka, kubuda kwegasi, kudzika, uye kurasikirwa zvachose kwekushanda kwekudzivirira.
Kune vagadziri veIGU uye zvikwata zvekutenga, iyi haisi yakajairika yekuisa chisimbiso sarudzo. Icho chisarudzo chekuvimbika kwechigadzirwa.
1. Basa rechokwadi rechisimbiso chechipiri muIGU systems
Magirazi ekuvharisa anoshandisa maviri-seal system:
Chisimbiso chekutanga (butyl sealant)
Inoshandiswa pane spacer
Main chipingamupinyi chegasi uye mwando
Inopa yekutanga airtightness
Chisimbiso chechipiri (silicone sealant kana polysulfide / polyurethane systems)
Structural reinforcement layer
Inopa simba remagetsi
Inochengetedza-kusimba kwenguva refu
Inodzivirira chisimbiso chekutanga kubva kumatambudziko ekunze
Mumashoko akapfava:
👉 Chisimbiso chekutanga chinochengeta gasi mukati.
👉 Chisimbiso chechipiri chinochengeta system pamwe chete.
Pasina chisimbiso chechipiri chakavimbika, chimiro cheIGU chichakundikana zvishoma nezvishoma kunyange kana chisimbiso chekutanga chakasimba.
2. Sei silicone inoshandiswa zvakanyanya sechipiri chisimbiso
Pakati pemasecondary seal system akasiyana, silicone sealant yave sarudzo inosarudzika mumitsetse yakawanda yemazuva ano yeIGU yekugadzira, kunyanya-yepamusoro pegirazi rekuvaka.
Zvikonzero zvinoshanda, kwete dzidziso:
(1) Kureba-kwenguva refu
IGUs inogara ichisangana:
Kuwedzera kupisa
Mhepo mutoro wekumanikidza
Kuvaka kufamba
Silicone inochengetedza kuchinjika kwemakumi emakore pasina kuita brittle.
(2) Yakanakisa kupikisa kwemamiriro ekunze
Sekondari zvisimbiso zvinoratidzwa kune:
UV mwaranzi
Mvura uye hunyoro
Tembiricha bhasikoro
Silicone inochengetedza kugadzikana pasi pe-nguva yakareba yekuratidzwa zviri nani pane akawanda organic sealants.
(3) Tsigiro yekuvimbika kwemaitiro
Kunyange isiri iyo yekutanga gasi chipingamupinyi, silicone inopa:
Spacer adhesion simba
Edge kugadzikana
Mutoro wekugovera rutsigiro
Izvi zvakakosha kune makuru egirazi mayuniti uye façade application.
3. Uko maIGU masisitimu anokundikana mumapurojekiti chaiwo
Kana insulating magirazi mayuniti achitadza mumunda, iyo midzi inokonzeresa inowanzo teverwa kumashure kwechipiri chisimbiso kuita nyaya:
(1) Gasi rinobuda nekufamba kwenguva
Kurasikirwa kweargon kana krypton gasi kunotungamirira ku:
Yakaderedzwa insulation performance
Kuwedzera kushandiswa kwesimba
Fogging pakati pepanes
Izvi zvinowanzoenderana nediki-kutadza kushanda museal system.
(2) Edge seal degradation
Kuratidzwa kune UV uye tembiricha kutenderera kunogona kukonzera:
Chisimbiso kuputika
Kurasikirwa kwekunamatira kune spacer
Zvishoma nezvishoma mvura mhute ingress
Kana unyoro hwapinda, IGU performance inodonha zvachose.
(3) Delamination yegirazi edge system
Muzviitiko zvakanyanya:
Sekondari chisimbiso chinoparadzanisa kubva girazi kana spacer
Kutendeseka kwemaitiro kunokanganiswa
Yese IGU inofanirwa kutsiviwa
Iyi inyaya-yekutadza kudhura kwakanyanya mumasisitimu efaçade.
4. Silicone vs polysulfide vs polyurethane muIGU zvisimbiso zvechipiri
Nepo silicone ichishandiswa zvakanyanya, haisi iyo yega sarudzo. Sarudzo dzekutenga kazhinji dzinosanganisira kuenzanisa masisitimu matatu makuru:
Silicone sealant
Strengths:
Yakanakisa UV kuramba
Kureba-kwenguva refu
Kusimba kwemamiriro ekunze kwakasimba
Kushanda kwakagadzikana mune façade application
Kuganhurirwa:
Mutengo wepamusoro
Inoda kunyatsogadzirisa kutonga kwekushandisa IGU
Polysulfide sealant
Strengths:
Good gas barrier properties
Inoshandiswa zvakanyanya mukugadzirwa kwechinyakare IGU
Mutengo{{0}unoshanda muzvishandiso zvakawanda
Kuganhurirwa:
Yakaderera UV kuramba ichienzaniswa nesilicone
Kuchembera kuita kunoenderana zvakanyanya nekuumbwa
Polyurethane sealant
Strengths:
Kunamatira kwakasimba
Zvakanaka mechanical properties
Inoshandiswa zvakanyanya mune mamwe maindasitiri IGU masisitimu
Kuganhurirwa:
UV senitivity
Kungango kanganisa-kwenguva refu munzvimbo dzakafumurwa
Mumazuva ano-anoshanda akakwira macurtain masisitimu, silicone iri kunyanya kufarirwa apo{1}}kusimba kwenguva refu uye kusangana nemamiriro ekunze kwakakosha.
5. Chii chinonyanya kukosha mune yechipiri silicone sealant kusarudzwa
Kune vagadziri veIGU nezvikwata zvinotenga zvinhu, misiyano yekushanda haionekwi ne "silicone vs non{-silicone" chete, asi nekugadzirwa kwemhando uye kuenderana kwemaitiro.
Zvinhu zvakakosha zvinosanganisira:
1. Adhesion kugadzikana kune girazi uye spacer
Chisimbiso chechipiri chinofanira kuchengetedza-chibvumirano chenguva refu kune:
Float glass
Girazi rakavharwa
Aluminium spacers
Warm edge systems
Kusakwana kunamatira kunotungamirira zvakananga kumucheto kukundikana.
2. Low permeability performance
Kunyangwe chisimbiso chekutanga chichibata gasi rakawanda, chisimbiso chechipiri chinofanirwa kutsigira kusimba kwehurongwa pasi pe-nguva refu yekushushikana.
3. Thermal cycling resistance
IGUs munzvimbo chaidzo dzinotarisana:
Masikati / husiku tembiricha inoshanduka
Kuchinja kwemamiriro ekunze kwemwaka
Rapid thermal shocks
Sealant inofanira kuramba yakagadzikana pasi pekudzokororwa kwekuwedzera uye kutenderera kutenderera.
4. Kuenderana nemitsara yekugadzira IGU
Mukugadzira maindasitiri, sealant inofanirwa kuenderana ne:
Automated dispensing systems
Kurapa kumhanya zvinodiwa
Mutsara wekugadzira kushanda zvakanaka
Spacer zvinhu uye machira
5. Batch-ku{2}}kuenderana
Kune vagadziri veIGU, kuwirirana kunowanzo kukosha kupfuura kuita kwepamusoro. Kusiyana kunokonzera:
Kusagadzikana kwekugadzirwa
Kutsauka kwemhando pakati pemabhechi
Kuwedzera kurambwa mitengo
6. Maitiro ekugadzira akakosha sekusarudzwa kwezvinhu
Kunyange -silicone yemhando yepamusoro inogona kutadza kana iyo IGU yekugadzira ikasadzorwa nemazvo.
Matambudziko ekugadzira anosanganisira:
(1) Kusvibiswa kwepamusoro
Girazi kana spacer nzvimbo dzakasvibiswa nemafuta, guruva, kana unyoro zvinoderedza kusimba kwekunamatira zvakanyanya.
(2) Ukobvu hwesimbi husina kunaka
Kunyanya kuonda → kusakwana kwerutsigiro rwechimiro
Kunyanya kukora → kusaenzana kurapa uye kuisa pfungwa pakushushikana
(3) Mamiriro asina kunaka ekurapa
Tembiricha uye humidity zvinokanganisa zvakananga crosslinking uye yekupedzisira kuita.
(4) Kusawirirana kusanganisa kana kugovera
Mune otomatiki masisitimu, chiyero chisina kururama kana kusanganisa kwakashata kunotungamira kune isina kusimba nzvimbo mukati mechisimbiso.
7. Mapoka ekutenga anofanirwa kuongorora sei IGU silicone sealants
Mukutenga chaiko sarudzo, zvinyorwa zvehunyanzvi zvakakosha.
Kuongorora kwakakodzera kunofanirwa kusanganisira:
IGU-chaiyo kuyedza kuenderana
Adhesion performance report
UV uye kupisa kuchembera data
Gasi permeability rutsigiro kuita
Industrial line kuenderana kusimbiswa
Mareferenzi-enguva refu yefaçade
Muzviitiko zvakawanda, data chaiyo yekuita purojekiti yakakosha kupfuura nhamba dzerabhoritari chete.
8. Apo silicone yechipiri chisimbiso chinowanzoshandiswa
Silicone{{0}based secondary seal systems inoshandiswa zvakanyanya mu:
MaIGU epamusoro-anosimudza maketeni
Façades yekuvaka yekutengeserana
Simba-rinoshanda rakaderera-E magirazi mayunitsi
Makuru ekugadzira glazing masisitimu
Structural glazing IGU magungano
Zvishandiso izvi zvese zvinogovana chinodikanwa chimwe chete: kugadzikana-kwenguva refu pasi pekugara uchiratidzwa kwezvakatipoteredza.
Mhedziso
Mune insulating glass units, chechipiri chisimbiso hachisi chekumashure-icho chigadziriso chakasimba chinotara{1}nguva yakareba kushanda.
Silicone sealant, kana yakanyatsogadzirwa uye yakanyatsobatanidzwa mukugadzirwa kweIGU, inopa chiyero chekusimba, kusimba, uye kuramba kwemamiriro ekunze izvo zvakakosha pakugadzira glazing yemazuva ano.
Kune zvikwata zvekutenga uye IGU vagadziri, kiyi yekutora iri nyore:
Iwe hausi kungosarudza sealant.
Uri kusarudza-kutendeseka kwenguva refu kwegirazi rega rega rinogadzirwa.
Nekuti kana IGU yangobuda mufekitori ichipinda mufaçade yechivako, kutadza haichisiri nyaya-inove nzira-yakakura mutengo.
