Kodi pali kusiyana kotani pakati pa weatherpoof sealants ndi structural sealants?

Zosindikizira za silicone zimatha kupirira kuchuluka kwa mphamvu, ndipo zomatira za silicone zolimbana ndi nyengo zimagwiritsidwa ntchito makamaka posindikiza madzi. Zomatira zamapangidwe a silicone zitha kugwiritsidwa ntchito ngati mafelemu ang'onoang'ono ndipo zimatha kupirira kupsinjika ndi mphamvu yokoka. Zomatira zolimbana ndi nyengo ya silicone zimangogwiritsidwa ntchito pobisalira ndipo sizingagwiritsidwe ntchito kusindikiza pamapangidwe.

Silicone Building Sealant ndi njira yochiritsira yosalowerera ndale yokhala ndi zomangira zamtundu wapamwamba kwambiri za silicone. Kukana kwabwino kwa nyengo, kukana kutentha kwapamwamba komanso kotsika -50 ° C + 150 ° C, kumamatira kwabwino, kumatha kutulutsidwa ndikugwiritsidwa ntchito m'malo osiyanasiyana anyengo, ndipo kumachitapo kanthu mwachangu ndi chinyezi mumlengalenga, kuchiritsa kukhala cholimba, Chapamwamba. ntchito ndi zotanuka silikoni sealant, akhoza kukana kukokoloka kwa chilengedwe monga mpweya ndi fungo, cheza ultraviolet ndi mvula. Amagwiritsidwa ntchito kwambiri pokonza ndi kusindikiza zitseko, mawindo ndi zokongoletsera zomangamanga.

Zina mwa zisonyezo zazikulu zaukadaulo za zosindikizira za silicone zolimbana ndi nyengo, kusanja, kutulutsa, ndi nthawi yowuma pamwamba kumadziwika ndi ntchito yomanga. Magwiridwe a chosindikizira chochiritsira cholimbana ndi nyengo makamaka ndichosamutsidwa ndi kutayika kwakukulu. Kutayika kwakukulu kwa zomatira zolimbana ndi nyengo ndizofanana ndi kuwonda kwa kutentha kwa zomatira zamapangidwe. Ndikofunikira kufufuza kusintha kwa ntchito kwa zomatira zolimbana ndi nyengo zitatha kugwiritsidwa ntchito kwa nthawi yayitali. Kuchuluka kwa chiwongoladzanja chochuluka, kumapangitsanso kuchepa kwakukulu pambuyo pogwiritsidwa ntchito kwa nthawi yaitali.

Ntchito yayikulu ya silicone yolimbana ndi nyengo ndi kusindikiza zolumikizira pakati pa mbale. Popeza kuti mbale nthawi zambiri zimakhudzidwa ndi kusintha kwa kutentha ndi kusinthika kwa kapangidwe kake, m'lifupi mwake mudzasinthanso. Izi zimafuna zomatira zolimbana ndi nyengo kuti zikhale ndi luso lotha kupirira kusamuka kwa olowa, ndipo sizidzasokoneza pansi pa chikhalidwe cha kusintha kwa nthawi yaitali m'lifupi mwake. zosiyana.

Silicone Structural Sealant ndi gawo limodzi, machiritso osalowerera ndale, opangidwa mwapadera kuti amangirire magalasi opangira magalasi pomanga makoma a nsalu. Ikhoza kutulutsidwa mosavuta ndikugwiritsidwa ntchito mumitundu yosiyanasiyana ya kutentha. Dalirani chinyezi chamumlengalenga kuti muchiritse kukhala modulus yabwino kwambiri, yolimba kwambiri, mphira wa silicone wokhuthala kwambiri. Chogulitsacho sichifuna choyambira kugalasi, ndipo chimatha kutulutsa bwino kwambiri.

Zomatira zomangira zimatanthawuza kumphamvu kwambiri (compressive mphamvu> 65MPa, zitsulo-zitsulo zabwino zomangira zomangira> 30MPa, kumeta ubweya> 18MPa), zimatha kupirira zolemetsa zazikulu, komanso kugonjetsedwa ndi ukalamba, kutopa, dzimbiri, ndi magwiridwe antchito mkati mwa moyo woyembekezeredwa. Chokhazikika, choyenera kumangiriza amphamvu. Zomatira zosamangika zimakhala ndi mphamvu zochepa komanso zosakhazikika bwino, ndipo zitha kugwiritsidwa ntchito pomangirira, kusindikiza ndi kukonza zinthu wamba komanso zosakhalitsa, ndipo sizingagwiritsidwe ntchito polumikizana ndi zomangamanga.
