Izizathu ezinokwenzeka kunye nezisombululo ezihambelanayo zengxaki yokubetha i-sealant drumming

A. Ukufuma okuphantsi kokusingqongileyo

Ukufuma okuphantsi kokusingqongileyo kubangela ukucotha ukunyangeka kwesitywina.Ngokomzekelo, entwasahlobo nasekwindla emantla elizwe lam, ukufuma komoya okuhambelanayo kuphantsi, ngamanye amaxesha kude kuhlale malunga ne-30% ye-RH ixesha elide.

Isisombululo: Zama ukukhetha ulwakhiwo lwamaxesha onyaka kwimiba yobushushu kunye nokufuma.

B. Umahluko omkhulu wobushushu bokusingqongileyo (umahluko ogqithisileyo wobushushu ngosuku olunye okanye iintsuku ezimbini ezikufutshane)

Ngethuba lenkqubo yokwakha, iyunithi yokwakha inethemba lokuba isantya sokunyanga i-sealant kufuneka sikhawuleze kangangoko kunokwenzeka, ukuze kuncitshiswe amathuba okuchatshazelwa yimiba yangaphandle.Nangona kunjalo, kukho inkqubo yokunyangwa kwe-sealant, ehlala ithatha iintsuku ezininzi.Ngoko ke, ukwenzela ukukhawulezisa isantya sokuphilisa iglue, abasebenzi bokwakha badla ngokuqhuba ukwakhiwa phantsi kweemeko ezifanelekileyo zokwakha.Ngokuqhelekileyo, imozulu (ingakumbi iqondo lokushisa kunye nomswakama) ikhethwa ukwakhiwa kwiqondo lokushisa elizinzile kwaye lilungele ukwakhiwa (igcinwe kwiqondo lokushisa elithile kunye nomswakama ixesha elide).

Isisombululo: Zama ukukhetha ixesha lonyaka kunye nexesha kunye nomahluko omncinci wobushushu bokwakha, njengokwakhiwa kwamafu.Ukongezelela, ixesha lokunyanga le-silicone ye-resistant-resistant sealant kufuneka libe lifutshane, elinokuqinisekisa ukuba i-sealant ayiyi kuhanjiswa ngamanye amandla angaphandle ngexesha lokunyanga ukuze kubangele iglue.

C. Izixhobo zephaneli, ubungakanani kunye nemilo

I-substrates ebotshelelwe ngama-sealants idla ngokuba yiglasi kunye ne-aluminium.Ezi substrates ziya kwanda kwaye zivumelane neqondo lokushisa njengoko ubushushu buguquka, nto leyo eya kubangela ukuba iglue ibe phantsi kokwelula okubandayo kunye noxinzelelo olushushu.

I-coefficient yokwandiswa komgca ikwabizwa ngokuba yi-coefficient yokwandiswa komgca.Xa ubushushu bento eqinileyo buguquka nge-1 degree Celsius, umlinganiselo wokutshintsha kobude bayo ukuya kubude bayo kwiqondo lobushushu lokuqala (akunyanzelekanga ukuba ube ngu-0°C) ubizwa ngokuba “yi-coefficient yokwandiswa komgca”.Iyunithi ngu-1/℃, kwaye isimboli ngu-αt.Inkcazo yayo ngu-αt=(Lt-L0)/L0∆t, oko kukuthi, Lt=L0 (1+αt∆t), apho i-L0 ubukhulu bokuqala bezinto eziphathekayo, i-Lt ubukhulu bezinto eziphathekayo kwi-t ℃, kwaye ∆t nguMahluko wobushushu.Njengoko kubonisiwe kule theyibhile ingentla, ubukhulu becala le-aluminiyam ipleyiti, kokukhona kucaca ngakumbi i-bulging phenomenon yeglue kwi-glue joint.I-deformation edibeneyo yepleyiti ye-aluminiyam enemilo ekhethekileyo inkulu kunepleyiti ye-aluminiyam eflethi.

Isisombululo: Khetha ipleyiti ye-aluminium kunye neglasi kunye ne-coefficient encinci yokwandisa umgca, kwaye ubeke ingqalelo ekhethekileyo kwicala elide (icala elifutshane) lephepha le-aluminium.Ukuqhuba ubushushu obusebenzayo okanye ukukhuselwa kwepleyiti ye-aluminium, njengokugubungela ipleyiti ye-aluminium ngefilimu ye-sunshade.Iskimu "sokulinganisa okwesibini" singasetyenziselwa ukwakhiwa.

D. Impembelelo yamandla angaphandle

Izakhiwo eziphakamileyo zixhomekeke kwimpembelelo ye-monsoon.Ukuba umoya unamandla, uya kubangela ukuba i-glue yemozulu iqhube.Uninzi lwezixeko kwilizwe lethu zikwindawo yemonsoon, kwaye izakhiwo zodonga lomkhusane ziya kugungqa kancinci ngenxa yoxinzelelo lomoya wangaphandle, okukhokelela kutshintsho kububanzi bamalungu.Ukuba iglue isetyenziswe xa umoya unamandla, i-sealant iya kukhupha ngenxa yokufuduka kweplate ngaphambi kokuba iphiliswe ngokupheleleyo.

Isisombululo: Ngaphambi kokufaka iglue, isikhundla sephepha le-aluminium kufuneka silungiswe kangangoko kunokwenzeka.Kwangaxeshanye, ezinye iindlela zingasetyenziselwa ukwenza buthathaka amandla angaphandle kwiphepha le-aluminium.Akuvunyelwe ukusebenzisa iglue phantsi kweemeko zomoya ogqithiseleyo.

E. ulwakhiwo olungafanelekanga

1. I-glue edibeneyo kunye nesiseko sezinto ezinomswakama ophezulu kunye nemvula;

2. Intonga yogwebu ikrwelwe ngempazamo ngexesha lolwakhiwo/ubunzulu bomphezulu bentonga yogwebu buhlukile;

3. Umcu we-foam/i-tape enamacala amabini awuzange ube mcaba phambi kokulinganisa, kwaye uye wadumba kancinci emva kokulinganisa.Ibonise into eyenzekayo emva kokulinganisa.

4. Intonga ye-foam ikhethwe ngokungachanekanga, kwaye i-foam ayinakuba yi-low-density foam sticks, ekufuneka ihambelane neenkcukacha ezifanelekileyo;

5. Ubukhulu bokulinganisa abanelanga, bubhityile kakhulu, okanye ubukhulu besayizi abulingani;

6. Emva kokuba i-substrate ye-splicing isetyenzisiwe, i-glue ayiqini kwaye ishukunyiswe ngokupheleleyo, ibangele ukufuduka phakathi kwe-substrates kunye nokwenza i-blisters.

7. Iglue esekelwe kutywala iya kukhula xa isetyenziswe phantsi kwelanga (xa ukushisa kwe-substrate kuphezulu).

Isisombululo: Ngaphambi kokwakhiwa, qiniseka ukuba zonke iintlobo ze-substrates zikwimeko yokwakhiwa kwemibandela ye-sealant echasene nemozulu, kwaye iqondo lokushisa kunye nomswakama kwindawo engqongileyo nazo zikwindawo efanelekileyo (iimeko zokwakha ezicetyiswayo).
