Ndi mavuto ati omwe ma sealant amakumana nawo m'nyengo yozizira?

1. Kuchiza kwapang'onopang'ono

The vuto loyamba kuti mwadzidzidzi dontho la kutentha yozungulira kumabweretsasilicone structural sealantndikuti imamva kuchiritsidwa panthawi yogwiritsira ntchito, ndipo mawonekedwe a silikoni ndi wandiweyani.

Njira yochiritsira ya silicone sealant ndi njira yopangira mankhwala, ndipo kutentha ndi chinyezi cha chilengedwe zimakhudzana ndi liwiro lake lakuchiritsa.Kwa gawo limodzisilicone structural sealants, kutentha kwapamwamba ndi chinyezi, m'pamenenso kuthamanga kwa machiritso kudzakhala kofulumira.M'nyengo yozizira, kutentha kumatsika kwambiri, ndipo panthawi imodzimodziyo, ndi chinyezi chochepa, kuchiritsa kwa chosindikizira chomangira kumakhudzidwa, kotero kuchiritsa kwa structural sealant kumachedwa.Nthawi zambiri, kutentha kukakhala kotsika kuposa 15 ℃, kuchiritsa kwapang'onopang'ono kwa structural sealant kumakhala koonekeratu.

Yankho: Ngati wosuta akufuna kumanga m'malo otsika kutentha, tikulimbikitsidwa kuti ayese mayeso a silicone sealant ang'onoang'ono asanayambe ntchito, ndikuyesa kuyesa kwa peel kuti atsimikizire kuti chosindikizira chokhazikika chikhoza kuchiritsidwa, kumamatira kuli bwino, ndipo maonekedwe alibe vuto.malo ogwiritsidwa ntchito.Komabe, kutentha kozungulirako kukakhala kotsika mpaka 4°C, sikoyenera kupanga chosindikizira chomangira.

Chosindikiziracho chimamatidwa pogwiritsa ntchito kutentha ndi chinyezi cha chilengedwe.

2. Mavuto ogwirizana

Ndi kuchepa kwa kutentha ndi chinyezi komanso kuchiritsa pang'onopang'ono, palinso vuto la kulumikizana pakati pa chosindikizira chokhazikika ndi gawo lapansi.Zomwe zimafunikira pakugwiritsa ntchitosilicone structural sealantzopangidwa ndi: malo aukhondo ndi kutentha kwa 10 ° C mpaka 40 ° C ndi chinyezi wachibale wa 40% mpaka 80%.Kupitilira zomwe zili pamwambazi zomwe zimafunikira kutentha, liwiro lomangirira limachepetsedwa, ndipo nthawi yolumikizana kwathunthu ndi gawo lapansi imatalika.Nthawi yomweyo, kutentha kukakhala kotsika kwambiri, kunyowa kwa zomatira ndi pamwamba pa gawo lapansi kumachepa, ndipo pangakhale chifunga chosawoneka bwino kapena chisanu pamwamba pa gawo lapansi, zomwe zimakhudza kumamatira pakati pa chosindikizira chokhazikika ndi chosindikizira chokhazikika. gawo lapansi.

Yankho: Pamene kutentha kocheperako kwa chosindikizira ndi 10 ° C, chosindikizira chomangika chimangiriridwa ndi gawo lapansi momwemo.Kuyesa kumamatira kuyenera kuchitidwa pamalo omangira otsika kutentha kuti atsimikizire kumamatira bwino musanamangidwe.Jakisoni wa fakitale wa structural sealant amathanso kufulumizitsa kuchiritsa kwa chosindikizira chomangika powonjezera kutentha ndi chinyezi cha chilengedwe momwe chosindikizira chomangira chimagwiritsidwa ntchito, ndipo nthawi yomweyo, ndikofunikira kuwonjezera nthawi yochiritsa.

3. Wonjezerani kukhuthala

Zosindikizira zomangamangazidzakhuthala pang'onopang'ono ndikukhala madzi ochepa pamene kutentha kumachepa.Pazinthu ziwiri zosindikizira zomangira, zosindikizira zomangika zomwe zimakulitsa kukhuthala zimawonjezera kupanikizika kwa makina a glue ndikuchepetsa kutulutsa kwa chosindikizira chomangika.Kwa chigawo chimodzi chosindikizira chosindikizira, chosindikizira chokhazikika chimakhuthala, kuwonjezereka kwa mfuti ya guluu kuti itulutse chosindikizira chomangika kumatha kutenga nthawi komanso kuvutikira ntchito zamanja.

Yankho: Ngati ntchito yomangayo ilibe mphamvu, kukhuthala kwa kutentha kochepa ndi chinthu chachilendo, ndipo palibe njira zowongolera zomwe zimafunikira.

Ngati ntchito yomanga ikugwira ntchito, ndizotheka kulingalira za kukulitsa kutentha kwa chosindikizira chokhazikika kapena kutengera njira zina zotenthetsera, monga kusunga chosindikizira m'chipinda chotenthetsera kapena chipinda chokhala ndi mpweya pasadakhale, kukhazikitsa chowotcha chotenthetsera mkati. gluing workshop, ndi kuonjezera
