Kusankha chosindikizira chachiwiri cha galasi loteteza kutentha

Galasi losunga mphamvu la nyumba monga nyumba zogona, lomwe lili ndi chitetezo chabwino kwambiri cha kutentha ndi mphamvu zoteteza mawu, komanso ndi lokongola komanso lothandiza. Chotsekera magalasi chotetezera kutentha sichimawerengera mtengo waukulu wa galasi lotetezera kutentha, koma ndi lofunika kwambiri kuti galasi lotetezera kutentha likhale lolimba komanso lotetezeka, ndiye mungasankhe bwanji?

Zokhudza galasi loteteza kutentha

Galasi loteteza kutentha limapangidwa ndi zidutswa ziwiri (kapena zingapo) za galasi ndi ma spacer omangiriridwa pamodzi. Mtundu wotsekera umagwiritsa ntchito njira ya glue strip ndi njira ya glue joint. Pakadali pano, chisindikizo chawiri mu kapangidwe ka glue joint sealing chimagwiritsidwa ntchito kwambiri. Kapangidwe kake kali monga momwe kawonetsedwera pachithunzichi: zidutswa ziwiri zagalasi zimalekanitsidwa ndi ma spacer, spacer ndi galasi zimatsekedwa ndi butyl glue kutsogolo, ndipo mkati mwa spacer mumadzazidwa ndi molecular seeve, ndipo m'mphepete mwa galasi ndi kunja kwa spacer zimapangidwa. Mpata umatsekedwa ndi sealant yachiwiri.

Mitundu ya zotsekera zachiwiri zagalasi loteteza kutentha

Pali mitundu itatu ikuluikulu ya zomatira zagalasi zotetezera kutentha: silicone, polyurethane ndi polysulfide. Komabe, chifukwa cha polysulfide, guluu wa polyurethane uli ndi kukana kukalamba kwa UV, ndipo ngati pamwamba pagalasi pakhala padzuwa kwa nthawi yayitali, kuchotsa gum kudzachitika. Ngati izi zitachitika, pepala lakunja la galasi lotetezera kutentha la khoma lobisika la galasi lidzagwa kapena kutseka galasi lotetezera kutentha la khoma lotetezedwa ndi mfundo kudzalephera. Kapangidwe ka mamolekyu a silicone sealant kumapangitsa silicone sealant kukhala ndi ubwino wokana kutentha kwambiri, kukana nyengo komanso kukana kukalamba kwa ultraviolet, ndipo nthawi yomweyo, kuchuluka kwa kuyamwa kwa madzi kumakhala kochepa, kotero silicone imagwiritsidwa ntchito kwambiri pamsika.

Zoopsa za Kugwiritsa Ntchito Molakwika

Mavuto omwe amadza chifukwa chosasankha bwino chosindikizira chachiwiri akhoza kugawidwa m'magulu awiri otsatirawa: choyamba ndi kutayika kwa ntchito yogwiritsira ntchito galasi lotetezera kutentha, ndiko kuti, ntchito yoyambirira ya galasi lotetezera kutentha yatayika; china chikugwirizana ndi chitetezo cha kugwiritsa ntchito galasi lotetezera kutentha— — Ndiko kuti, chiopsezo cha chitetezo chomwe chimabwera chifukwa cha kugwa kwa pepala lakunja la galasi lotetezera kutentha.

Zifukwa zomwe zimalepheretsa kutseka magalasi nthawi zambiri zimakhala izi:

Pozindikira ngozi za khalidwe la makoma a nsalu, kusanthula kumasonyeza kuti pali zifukwa zitatu zazikulu zomwe zimapangitsa kuti galasi lakunja ligwere:

1. Kugwirizana kwa chotetezera galasi chachiwiri;

2. Pofuna kuchepetsa ndalama, magulu oyenerera amafunafuna mitengo yotsika mosazindikira, ndipo chosindikizira chachiwiri chagalasi chotetezera kutentha chimagwiritsa ntchito zomatira zomangira zosagwiritsa ntchito silicone monga polysulfide ndi silicone construction sealants;

3. Ogwira ntchito zomangamanga ena ndi osadziwa bwino ntchito yawo komanso okhwima, zomwe zimapangitsa kuti pakhale vuto la kufalikira kwa jekeseni wa chotetezera magalasi chachiwiri.

Chenjezo posankha chosindikizira chachiwiri

Chotsekera chachiwiri cha galasi lotetezera kutentha chimakhudza kwambiri ubwino ndi moyo wa ntchito ya galasi lotetezera kutentha. Chotsekera cha kapangidwe ka galasi lotetezera kutentha chimagwirizana mwachindunji ndi chitetezo cha khoma la nsalu. Chifukwa chake, sitiyenera kungosankha chinthu choyenera, komanso kusankha chinthu choyenera.

Choyamba, ndi yogwirizana ndi miyezo ndipo imapezeka nthawi iliyonse yomwe mukufuna. Chachiwiri, musagwiritse ntchito zomatira zodzaza mafuta. Pomaliza, sankhani mtundu wodziwika bwino monga junbond
