A. Ukufuma okuphantsi kokusingqongileyo
Ukufuma okuphantsi kokusingqongileyo kubangela ukucotha kokuqina kwe-sealant. Umzekelo, entwasahlobo nasekwindla kumantla elizwe lam, ukufuma komoya kuphantsi, ngamanye amaxesha kuhlala malunga ne-30% RH ixesha elide.
Isisombululo: Zama ukukhetha ulwakhiwo lwexesha lonyaka kwimiba yobushushu kunye nokufuma.
B. Umahluko omkhulu kubushushu obungqongileyo (umahluko omkhulu kubushushu ngosuku olunye okanye kwiintsuku ezimbini ezikufutshane)
Ngexesha lenkqubo yokwakha, iyunithi yokwakha inethemba lokuba isantya sokucocwa kwe-sealant kufuneka sikhawuleze kangangoko, ukuze kuncitshiswe amathuba okuba ichaphazeleke zizinto zangaphandle. Nangona kunjalo, kukho inkqubo yokucocwa kwe-sealant, edla ngokuthatha iintsuku ezininzi. Ke ngoko, ukuze kukhawuleziswe isantya sokucocwa kweglue, abasebenzi bokwakha badla ngokwenza ulwakhiwo phantsi kweemeko ezifanelekileyo zokwakha. Ngokwesiqhelo, imozulu (ngokuyintloko ubushushu kunye nokufuma) ikhethwa ukuze kwakhiwe kubushushu obuzinzileyo nobufanelekileyo kwakhiwe (obugcinwa kubushushu obuthile kunye nokufuma ixesha elide).
Isisombululo: Zama ukukhetha ixesha lonyaka nexesha elinomahluko omncinci wobushushu bokwakha, njengokwakhiwa okunamafu. Ukongeza, ixesha lokunyanga le-sealant engamelaniyo nemozulu ye-silicone kufuneka libe lifutshane, nto leyo enokuqinisekisa ukuba i-sealant ayizukushenxiswa ngamanye amandla angaphandle ngexesha lenkqubo yokunyanga ukuze iglu idumbe.
C. Izinto zephaneli, ubungakanani kunye nemilo
Izinto ezidityaniswe nezitywini zihlala ziyiglasi kunye ne-aluminium. Ezi zinto ziya kwanda kwaye zinciphe ngobushushu njengoko ubushushu butshintsha, nto leyo eya kubangela ukuba iglu ibekwe kwindawo ebandayo kwaye icinezelwe ngobushushu.
I-coefficient yokwandiswa okuthe ngqo ikwabizwa ngokuba yi-coefficient yokwandiswa okuthe ngqo. Xa ubushushu bento eqinileyo butshintsha nge-1 degrees Celsius, umlinganiselo wokutshintsha kobude bayo ukuya kubude bayo kubushushu bokuqala (akunyanzelekanga ukuba ibe yi-0°C) ubizwa ngokuba yi-"coefficient yokwandiswa okuthe ngqo". Iyunithi yi-1/℃, kwaye uphawu yi-αt. Inkcazo yayo yi-αt=(Lt-L0)/L0∆t, oko kukuthi, i-Lt=L0 (1+αt∆t), apho i-L0 ibukhulu bokuqala bezinto, i-Lt ibukhulu bezinto kwi-t ℃, kwaye i-∆t yi-Difference yobushushu. Njengoko kubonisiwe kwitheyibhile engentla, okukhona ubukhulu bepleyiti ye-aluminium bukhulu, kokukhona i-glue ethe tyaba iyabonakala ngakumbi. Ukuguquguquka kwe-joint yepleyiti ye-aluminium enemilo ekhethekileyo kukhulu kune-flat aluminium plate.
Isisombululo: Khetha ipleyiti ye-aluminiyam kunye neglasi ene-coefficient encinci yokwandisa umgca, kwaye unike ingqalelo ekhethekileyo kwicala elide (icala elifutshane) leshiti ye-aluminiyam. Ukuqhuba ubushushu okusebenzayo okanye ukukhuselwa kwepleyiti ye-aluminiyam, njengokugubungela ipleyiti ye-aluminiyam ngefilimu yomthunzi welanga. Iskimu "sobukhulu besibini" singasetyenziselwa ukwakha.
D. Impembelelo yamandla angaphandle
Izakhiwo eziphakamileyo zichaphazeleka lula yimvula enkulu. Ukuba umoya unamandla, uya kubangela ukuba iglu egubungeleyo ivuthuluke. Uninzi lwezixeko kwilizwe lethu zikwindawo yemvula enkulu, kwaye izakhiwo zodonga lwekhethini ziya kushukuma kancinci ngenxa yoxinzelelo lomoya wangaphandle, nto leyo ebangela utshintsho kububanzi bamalungu. Ukuba iglu isetyenziswa xa umoya unamandla, itywina iya kuphuma ngenxa yokushenxa kwepleyiti ngaphambi kokuba inyangeke ngokupheleleyo.
Isisombululo: Ngaphambi kokufaka iglu, indawo yeshiti yealuminiyam kufuneka ilungiswe kangangoko kunokwenzeka. Kwangaxeshanye, ezinye iindlela zingasetyenziswa ukwenza buthathaka impembelelo yamandla angaphandle kwishiti yealuminiyam. Akuvumelekanga ukufaka iglu phantsi kwemeko yomoya ogqithisileyo.
E. ulwakhiwo olungafanelekanga
1. I-glue kunye nezinto ezisisiseko zinomswakama ophezulu kunye nemvula;
2. Intonga yefoam ikrwelwe ngengozi ngexesha lokwakhiwa/ubunzulu bomphezulu wentonga yefoam bahlukile;
3. I-foam strip/i-tape enamacala amabini ayizange ithambeke ngaphambi kokuba yenziwe ubungakanani, kwaye yadumba kancinci emva kokwenziwa ubungakanani. Yabonisa into yokudumba emva kokwenziwa ubungakanani.
4. Intonga yefoam ayikhethwanga kakuhle, kwaye ifoam ayinakuba ziintonga zefoam ezinoxinano oluphantsi, ekufuneka zihambelane nemigaqo efanelekileyo;
5. Ubukhulu bobukhulu alwanelanga, buncinci kakhulu, okanye ubukhulu bobukhulu abulingani;
6. Emva kokuba i-substrate yokuqhawula isetyenzisiwe, iglu ayiqini kwaye ayishukunyiswa ngokupheleleyo, nto leyo ebangela ukufuduka phakathi kwe-substrates nokwenza ama-blister.
7. Iglu esekwe kwi-alcohol iya kukhukhumala xa isetyenziswa phantsi kwelanga (xa ubushushu bomphezulu we-substrate buphezulu).
Isisombululo: Ngaphambi kokuba wakhe, qiniseka ukuba zonke iintlobo ze-substrates zikwimeko yokwakha ye-sealant enganyangekiyo yimozulu, kwaye ubushushu kunye nokufuma kwindalo nako kukwinqanaba elifanelekileyo (iimeko zokwakha ezicetyiswayo).
