Iindaba

Imichilo yokutywina yenye yezona zinto zibalulekileyo zomnyango kunye nefestile. Zisetyenziswa kakhulu kwiisakhelo zesakhelo, iglasi yefreyimu kunye nezinye iindawo. Badlala indima yokutywina, ukuthintela amanzi, ukugquma isandi, ukufunxa umothuko nokugcina ubushushu. Ziyafuneka ukuba zibe namandla afanelekileyo okuqina, ukuqina, ukuxhathisa ubushushu kunye nokumelana nokuguga.

Imichilo yokutywinwa kunye neeprofayili zidityanisiwe ukuze kufezekiswe ukusebenza okufunekayo kokutywinwa, okuchatshazelwa yinto ephambili, indlela yokufakela, uluhlu olusebenzayo lokunyanzeliswa, ukunyanzeliswa kwamandla kunye nokuma kwecandelo le-cross-section of strips.
Imichilo yokutywina inokwahlulwa ibe yimichilo yemathiriyeli enye kunye nemicu edibeneyo yemathiriyeli ngokwezinto eziphathekayo.

Imicu yempahla enye ikakhulu ibandakanya imicu yokutywina ye-EPDM, imicu yokutywina yerabha ye-silicone (MVQ), i-thermoplastic vulcanized strips (TPV), kunye nemicu yeplastiki ye-polyvinyl chloride (PVC). Imicu yemathiriyeli edityanisiweyo ikakhulu ibandakanya imicu yocingo, imicu yokutshiza engaphezulu, imicu ethambileyo neqinileyo edityanisiweyo, imicu edityanisiweyo yesiponji, imicu eyongezelekayo ngamanzi, kunye nemicu egqunyiweyo.

Iimeko ezisebenzayo zeentlobo ezahlukeneyo zemicu yokutywina esetyenziswa ngokuqhelekileyo iboniswe kwitheyibhile engezantsi.

Imichilo yokutywina ye-EPDM ineempawu ezisisiseko ezisisiseko (amandla okuqina, ukomelela ngexesha lekhefu, kunye noxinzelelo olusisigxina), ukumelana nemozulu ebalaseleyo, ukumelana nobushushu obuphezulu kunye nobuphantsi, ukumelana nomhlwa, kunye nokusebenza okugqwesileyo okugqwesileyo. Okwangoku zisetyenziswa ngokubanzi kwintsimi yeengcango kunye neefestile.
Uluhlu olucetyiswayo lobushushu obusebenzayo lwemicu yokutywina eqhelekileyo: Izinto ze-EPDM yi-60℃～150℃, imathiriyeli yeMVQ yi-60℃～300℃, imathiriyeli yeTPV yi-40℃～150℃, kunye nePVC yi-25℃～70℃ .
Imicu yokutywina inokohlulwa ibe yintlobo yokucinezela, uhlobo lokungena, kunye nohlobo lokuncamathelisa ngokwendlela yokufakela. Zinokwahlulwa zibe yimicu yokutywina yefreyim-sash, imicu yokutywina yeglasi, kunye nemicu yokutywina ephakathi ngokwendawo yokufakela iingcango kunye neefestile.
I-frame-sash node yebhulorho ephukileyo ye-aluminium alloy umnyango kunye nefestile iboniswe kumzobo ongezantsi.

Ubume obunqamlezileyo bomgca wokutywina we-frame-sash kufuneka ukhethwe njenge-semi-enclosed okanye evalelwe ngokweemfuno. Xa uyilo olufunekayo lunoluhlu olukhulu lokusebenza okanye iimfuno zokusebenza zokutywinwa okuphezulu, isakhiwo esivaliweyo kufuneka sikhethwe.

Indlela yokufakela umgca wokutywina phakathi kwesakhelo kunye ne-sash kufuneka ibe yi-press-fit install. Uyilo lobungakanani benxalenye yofakelo lomtya kufuneka luqinisekise ukuba aluwi kwaye luhambelana ngokuqinileyo neprofayili yeprofayili.
Umtya wokutywina phakathi kwesakhelo kunye nomtya ukwabizwa ngokuba ngumcu wokutywina ongundoqo okanye umcu wokutywina we-isobaric. Idlala indima yokuthintela ukuhanjiswa komoya kunye nemitha yobushushu kwiprofayili. Kufuneka ihlangabezane neemfuno zokutywinwa kunye neemfuno zamandla okuvulwa nokuvala iingcango kunye neefestile.
Iimfuno zesayizi yendawo yokufakela yomgca wokutywina phakathi kwesakhelo kunye neglasi ichazwe kwi-JGJ 113-2015 "iKhowudi yobuGcisa yokuSebenza kweGlasi ye-Architectural", jonga itafile engezantsi.

Phakathi kwazo, imilinganiselo ye-a, b, kunye no-c iboniswe kumzobo ongezantsi.

Iimilo eziqhelekileyo ezinqamlezileyo zomgca wokutywina phakathi kwesakhelo kunye neglasi ziboniswe kumzobo ongezantsi, kwaye indlela yokufakela i-press-fit install ivame ukwamkelwa.

Ukuthetha ngomgca wokutywina phakathi kwesakhelo kunye neglasi, kukho omnye umbuzo ofanele ukuxoxa ngawo, oko kukuthi, kungcono ukusebenzisa imichilo yokutywina okanye i-sealants phakathi kwesakhelo kunye neglasi?
Okwangoku, uninzi lweenkampani zenkqubo yomnyango kunye nefestile ekhaya nakwamanye amazwe zisebenzisa imicu njengokhetho lokuqala lokutywinwa kweglasi. Oku kungenxa yokuba umtya werabha yimveliso yemveliso, umgangatho wofakelo ulawuleka ngakumbi, kwaye kulula ukuwutshintsha.
Ngokumalunga nokusebenza kokufaka i-sealant, nangona i-JGJ 113-2015 "iKhowudi yoBuchwephesha yokuSebenza kweGlasi yoKwakha" ibonelela ngemimiselo yokukhutshwa kwangaphambili nangasemva, okulinganayo nokuvuma le ndlela, ayikakhuthazwa ukwenza oko kwisiza kwezi zilandelayo. izizathu:
Umgangatho wokufaka i-sealant kwisiza awulawuleki, ngakumbi ubunzulu bokufaka i-sealant.
I-T / CECS 581-2019 "Ikhowudi yoBuchule yokuSebenza kweSakhiwo esiHlangeneyo soSakhiwo" sibonelela ngeefom ezisisiseko kunye nezakhiwo zokutywinwa ngokubambisana, jonga itafile engezantsi.

Ingabonwa ukuba amanyathelo ahambelanayo kufuneka athathwe ukulawula umgangatho wokwakha ukutywinwa kwamalungu e-butt kunye ne-intersection joints.
Umzekelo, ikhonkco langaphandle lokutywina lodonga oluqhelekileyo lweglasi efihliweyo ludonga lokutywina, kwaye umgangatho wokwakha ulawulwa yintonga ye-foam. Iglasi kunye nesakhelo esiqhotyoshelweyo zidibaniswe ngamacangci aphindwe kabini ukulawula ububanzi kunye nobukhulu be-adhesive yesakhiwo, njengoko kuboniswe kumzobo ongezantsi.

Iiprofayili zeendawo zokufakela iifestile ze-aluminium alloy kunye neglasi yefestile yeplastiki zizo zonke iiprofayili ezinodonga oluncinci - i-glass beading, ingalo yeprofayili yangaphandle, njl., kwaye ayinayo imiqathango yokulawula ububanzi kunye nobukhulu be-sealant.
Ukongeza, ukusebenzisa i-sealant yangaphandle emva kokufaka iglasi kuyingozi kakhulu. Uninzi lweengcango kunye nofakelo lwefestile lugqitywe ngaphakathi, ngelixa i-sealant yangaphandle kufuneka ifakwe ngaphandle. Kuyingozi xa kungekho qonga lokusebenza langaphandle njenge-scaffolding, iibhasikithi zokuxhoma, kunye neelori ze-boom, ngakumbi xa iipaneli zeglasi zikhulu.
Enye ingxaki eqhelekileyo yeyokuba uninzi lweengcango zaseYurophu kunye neenodi zenkqubo yefestile azinazo izakhelo zangaphandle kunye nemicu yokutywina, njengoko kubonisiwe kulo mfanekiso ungezantsi.

Olu luyilo alukho ukusika iikona kodwa luqwalaselo lokuhambisa amanzi.
Iingcango kunye neefestile ziya kuba nemingxuma yokuhambisa amanzi kwisixhobo sesakhelo esithe tyaba okanye isiseko esithe tyaba esisezantsi kwesahlulelo ngasinye (kubandakanywa izahlulo ezisisigxina kunye nezahlulo ezivulekileyo) ukuze amanzi angena kwiingcango kunye neefestile akhutshwe ngaphandle.

Ukuba isakhelo secala langaphandle kunye nomgca wokutywina wefeni zifakwe, ziya kwenza indawo evaliweyo kunye nomgca wokutywina ophakathi, ongekho ukulungelelaniswa kwe-isobaric drainage.
Ukuthetha nge-drainage ye-isobaric, unokwenza umfuniselo omncinci: gcwalisa ibhotile yamanzi amaminerali ngamanzi, ugxobhoze imingxuma emincinci kwi-cap yebhotile, kwaye ujike ibhotile ijonge phantsi, kunzima ukuba amanzi akhuphe kule mingxuma encinci, ngoko ke senza kwakhona imingxunya emincinci ezantsi kwebhotile, kwaye amanzi anokukhupha ngokulula kwimingxunya emincinci yebhotile.
Lo ngumgaqo osisiseko we-isobaric drainage yeengcango kunye neefestile.
Kulungile, masenze isishwankathelo
Imicu yokutywina yenye yezona zinto zibalulekileyo zomnyango kunye nefestile, ezisetyenziswa kakhulu kwiifeni zesakhelo, iglasi yefreyimu kunye namanye amacandelo, idlala indima yokutywina, ukuthintela amanzi, ukugqunywa kwesandi, ukufunxa ukothuka, ukugcinwa kobushushu, njl. ukomelela okulungileyo, ukuqina, ukumelana nobushushu kunye nokumelana nokuguga.
Imichilo yokutywina inokwahlulwa ibe yimichilo yemathiriyeli enye kunye nemicu edibeneyo yemathiriyeli ngokwezinto eziphathekayo. Okwangoku, imichilo yokutywina esetyenziswa ngokuqhelekileyo kwintsimi yeengcango kunye neefestile ibandakanya i-EPDM yokutywina imichilo, i-silicone rubber (MVQ) yokutywina imichilo, i-thermoplastic vulcanized strips (TPV), i-plasticized polyvinyl chloride strips (PVC), njl.
Imicu yokutywina inokohlulwa ibe yintlobo yokucinezela, uhlobo lokungena, kunye nohlobo lokuncamathelisa ngokwendlela yokufakela. Ngokwendawo yokufakela iingcango kunye neefestile, zinokwahlulwa zibe yimichilo yokutywina i-frame-sash, imicu yokutywina yeglasi, kunye nemicu yokutywina ephakathi.
Ngaba kungcono ukusebenzisa imicu yokutywina okanye izitywini phakathi kweefreyimu kunye neeglasi? Ngokumalunga nokulawulwa komgangatho wokwakha kunye nokhuseleko lokwakhiwa kwendawo, umbhali uncoma ukusebenzisa imicu yokutywina endaweni ye-sealants kwisayithi.
