Zomwe zingatheke ndi mayankho ofananira avuto la sealant druming

A. Chinyezi chochepa cha chilengedwe

Chinyezi chochepa cha chilengedwe chimayambitsa kuchiritsa kwapang'onopang'ono kwa sealant.Mwachitsanzo, mu kasupe ndi autumn kumpoto kwa dziko langa, chinyezi wachibale wa mpweya ndi otsika, nthawi zina ngakhale kuchedwa kuzungulira 30% RH kwa nthawi yaitali.

Yankho: Yesani kusankha kamangidwe ka nyengo pa nkhani za kutentha ndi chinyezi.

B. Kusiyana kwakukulu kwa kutentha kwa chilengedwe (kusiyana kwakukulu kwa kutentha tsiku lomwelo kapena masiku awiri oyandikana nawo)

Panthawi yomanga, gawo lomangali likuyembekeza kuti kuthamanga kwa machiritso a sealant kuyenera kukhala kofulumira, kuti achepetse mwayi wokhudzidwa ndi zinthu zakunja.Komabe, pali njira yochizira ma sealant, yomwe nthawi zambiri imatenga masiku angapo.Choncho, pofuna kufulumizitsa kuthamanga kwa guluu, ogwira ntchito yomanga nthawi zambiri amamanga pamikhalidwe yoyenera yomanga.Kawirikawiri, nyengo (makamaka kutentha ndi chinyezi) imasankhidwa kuti imangidwe pa kutentha komwe kumakhala kokhazikika komanso koyenera kumanga (kusungidwa pa kutentha kwina ndi chinyezi kwa nthawi yaitali).

Yankho: Yesani kusankha nyengo ndi nthawi yokhala ndi kusiyana pang'ono kwa kutentha kwa zomangamanga, monga kupanga mitambo.Kuonjezera apo, nthawi yochiritsa ya silicone yolimbana ndi nyengo imayenera kukhala yochepa, yomwe ingathenso kuonetsetsa kuti chosindikizira sichidzasunthidwa ndi mphamvu zina zakunja panthawi yochiritsira kuti zipangitse guluu kuphulika.

C. gulu zinthu, kukula ndi mawonekedwe

Magawo omangika ndi zosindikizira nthawi zambiri amakhala magalasi ndi aluminiyamu.Magawo awa adzakula ndikulumikizana ndi kutentha pamene kutentha kumasintha, zomwe zimapangitsa guluu kukhala ndi kuzizira kozizira komanso kukanikiza kotentha.

Coefficient of linear expansion imatchedwanso coefficient of linear expansion.Pamene kutentha kwa chinthu cholimba kumasintha ndi 1 digiri Celsius, chiŵerengero cha kusintha kwa kutalika kwake mpaka kutalika kwake pa kutentha koyambirira (osati kwenikweni 0 ° C) kumatchedwa "coefficient of linear expansion".Chigawo ndi 1/℃, ndipo chizindikiro ndi αt.Tanthauzo lake ndi αt = (Lt-L0)/L0∆t, ndiko kuti, Lt=L0 (1+αt∆t), pomwe L0 ndiye kukula koyambirira kwazinthu, Lt ndi kukula kwazinthu pa t ℃, ndipo ∆t ndi Kusiyana kwa kutentha.Monga momwe tawonetsera pamwambapa, kukula kwake kwa mbale ya aluminiyamu kumapangitsa kuti guluu likhale lodziwika bwino.Kupindika kophatikizana kwa mbale ya aluminiyamu yooneka ngati yapadera ndikokulirapo kuposa mbale ya aluminium yosalala.

Yankho: Sankhani mbale ya aluminiyamu ndi galasi yokhala ndi kagawo kakang'ono kamene kakukulirakulira, ndipo samalani kwambiri ndi mbali yayitali (mbali yayifupi) ya pepala la aluminiyamu.Kutentha kothandiza kapena kuteteza mbale ya aluminiyamu, monga kuphimba mbale ya aluminiyamu ndi filimu ya sunshade.Ndondomeko ya "secondary sizing" ingagwiritsidwenso ntchito pomanga.

D. Chikoka cha mphamvu zakunja

Nyumba zokwera kwambiri zimatha kukhudzidwa ndi mphepo yamkuntho.Ngati mphepo ndi yamphamvu, imapangitsa guluu wanyengo kuphulika.Mizinda yambiri m'dziko lathu ili m'dera la monsoon, ndipo nyumba zotchinga khoma zidzagwedezeka pang'ono chifukwa cha kupanikizika kwa mphepo yakunja, zomwe zimabweretsa kusintha kwa m'lifupi mwa mgwirizano.Ngati guluu likugwiritsidwa ntchito pamene mphepo imakhala yamphamvu, chosindikiziracho chidzaphulika chifukwa cha kusuntha kwa mbaleyo isanachiritsidwe.

Yankho: Musanagwiritse ntchito guluu, malo a pepala la aluminiyamu ayenera kukhazikika momwe angathere.Nthawi yomweyo, njira zina zitha kugwiritsidwanso ntchito kufooketsa mphamvu yakunja pa pepala la aluminiyamu.Ndikoletsedwa kugwiritsa ntchito guluu pansi pa mphepo yamkuntho.

E. kumanga kosayenera

1. Guluu ndi zinthu zoyambira zimakhala ndi chinyezi chambiri komanso mvula;

2. Ndodo ya thovu imakandwa mwangozi pakumanga/kuya kwa pamwamba kwa ndodo kumasiyana;

3. Mzere wa thovu/m'mbali-mbali ziwiri sunaphwanyidwe usanawuzidwe, ndipo unkatukumuka pang'ono utatha kukula.Izo zinawonetsa kubwebweta chodabwitsa pambuyo sizing.

4. Ndodo ya chithovu imasankhidwa molakwika, ndipo chithovucho sichingakhale chithovu chochepa kwambiri, chomwe chiyenera kutsata ndondomeko zoyenera;

5. Makulidwe a kukula sikokwanira, kuonda kwambiri, kapena makulidwe ake siling'ono;

6. Pambuyo pa gawo lapansi la splicing, guluu silimalimba ndikusuntha kwathunthu, zomwe zimapangitsa kusamuka pakati pa magawowo ndikupanga matuza.

7. Guluu wokhala ndi mowa adzaphulika akagwiritsidwa ntchito pansi pa dzuwa (pamene kutentha kwa gawo lapansi kuli kwakukulu).

Yankho: Musanamangidwe, onetsetsani kuti magawo amtundu uliwonse ali pamikhalidwe yomanga zinthu zosagwirizana ndi nyengo, komanso kutentha ndi chinyezi m'malo omwe ali m'malo oyenerera (mikhalidwe yomanga yovomerezeka).
