Ezinkathini zasekwindla nasebusika, njengoba umswakama ohlobene emoyeni uncipha futhi nomehluko wamazinga okushisa phakathi kwasekuseni nakusihlwa ukhula, ingaphezulu lamajoyinti anamathelayo wezindonga zamakhethini engilazi kanye nezindonga zamakhethini zephaneli ye-aluminium kancane kancane zizophuma futhi ziwohloke ezindaweni ezihlukahlukene zokwakha. . Ngisho namanye amaphrojekthi eminyango namafasitela angase ahlangabezane nokuguquguquka kwendawo kanye nokuphuma kwamajoyinti anamathelayo ngosuku olufanayo noma phakathi nezinsuku ezimbalwa zokuvalwa. Siyibiza ngokuthi i-sealant bulging.
1. Kuyini ukugoqa kwe-sealant?
Inqubo yokwelapha yengxenye eyodwa yokwakhiwa kwe-silicone sealant yesimo sezulu incike ekuphenduleni kunomswakama emoyeni. Uma isivinini sokuphulukisa se-sealant sihamba kancane, isikhathi esidingekayo sokujula okwanele kokupholisa ubuso sizoba side. Lapho ubuso be-sealant bungakaqini ekujuleni okwanele, uma ububanzi be-adhesive seam bushintsha ngokuphawulekayo (ngokuvamile ngenxa yokwanda okushisayo nokwehliswa kwephaneli), ingaphezulu le-adhesive seam lizothinteka futhi lingalingani. Ngezinye izikhathi kuba yiqhubu phakathi kwawo wonke umthungo wokunamathisela, ngezinye izikhathi kuba iqhubu okuqhubekayo, futhi ngezinye izikhathi kuba deformation esontekile. Ngemuva kokwelashwa kokugcina, le mithungo yokunamathela engalingani yendawo yonke iqinile ngaphakathi (hhayi amabhamuza angenalutho), iqoqo elibizwa ngokuthi "i-bulging".
Ukuqhuma komthungo wokunamathela wodonga lwamakhethini e-aluminium
Ukuqhuma kwe-adhesive seam yodonga lwamakhethini engilazi
Ukuqhuma kwe-adhesive seam yokwakhiwa komnyango namafasitela
2. Kwenzeka kanjani i-Bulging?
Isizathu esiyisisekelo sento ethi "bulging" ukuthi ingcina idlula kakhulu futhi iguquguquke ngesikhathi senqubo yokuphulukisa, okuwumphumela womthelela obanzi wezici ezifana nesivinini sokuphulukisa se-sealant, ubukhulu bokuhlangana okunamathelayo, impahla kanye nosayizi wephaneli, indawo yokwakha, kanye nekhwalithi yokwakha. Ukuze uxazulule inkinga ye-bulging emigqeni yokunamathisela, kuyadingeka ukuqeda izici ezingathandeki ezibangela ukuqhuma. Kuphrojekthi ethile, ngokuvamile kunzima ukulawula ngokuzenzakalelayo izinga lokushisa kwemvelo kanye nomswakama, futhi impahla yephaneli nosayizi, kanye nomklamo wokuhlanganisa okunamathelayo, nakho kunqunywe. Ngakho-ke, ukulawulwa kungafinyelelwa kuphela ohlotsheni lwe-sealant (umthamo wokunamathisela okunamathiselwe kanye nesivinini sokuphulukisa) kanye noshintsho lokushintsha kwezinga lokushisa kwemvelo.
A. Amandla okunyakaza kwe-sealant:
Kuphrojekthi ethile yodonga lwamakhethini, ngenxa yamanani angashintshi osayizi wepuleti, i-coefficient yokwandisa umugqa wento yephaneli, kanye nokushintsha kwezinga lokushisa lonyaka lodonga lwamakhethini, amandla amancane okunyakaza kwe-sealant angabalwa ngokusekelwe kububanzi obuhlangene obuhleliwe. Uma ilunga lilincane, i-sealant enekhono eliphezulu lokunyakaza idinga ukukhethwa ukuze ihlangabezane nezidingo zokuguqulwa kwamalunga.
B. Isivinini sokuphulukisa se-sealant:
Njengamanje, i-sealant esetshenziselwa ukwakhiwa kwamalunga e-China iningi lokunamathela kwe-silicone engathathi hlangothi, engahlukaniswa ngohlobo lwe-oxime yokwelapha kanye nohlobo lokwelapha lwe-alkoxy ngokuya ngesigaba sokuphulukisa. Isivinini sokuphulukisa se-adhesive silicone ye-oxime siyashesha kune-alkoxy silicone adhesive. Ezindaweni zokwakha ezinamazinga okushisa aphansi (4-10 ℃), umehluko omkhulu wezinga lokushisa (≥ 15 ℃), kanye nomswakama ophansi ohlobene (<50%), ukusetshenziswa kwe-adhesive silicone ye-oxime kungaxazulula izinkinga eziningi "ze-bulging". Ukushesha kwejubane lokuphulukisa le-sealant, amandla ayo okumelana nokuguqulwa kwamalunga ngesikhathi sokuphulukiswa anamandla; Uma ijubane lokuphulukisa lihamba kancane futhi ukunyakaza okukhulu nokuguquguquka kwelunga, kuba lula ukuthi i-adhesive joint iqhume.
C. Izinga lokushisa nokuswakama kwemvelo yendawo yokwakha:
Ingxenye eyodwa yokwakhiwa kwe-silicone sealant engamelana nesimo sezulu ingalapha kuphela ngokusabela ngomswakama emoyeni, ngakho-ke izinga lokushisa kanye nomswakama wendawo yokwakha kunomthelela othile ejubaneni layo lokuphulukisa. Ngokuvamile, izinga lokushisa eliphakeme kanye nomswakama kubangela ukusabela okusheshayo kanye nesivinini sokwelapha; Izinga lokushisa eliphansi kanye nomswakama kubangela ijubane lokuphendula elipholile kancane, okwenza kube lula ukuthi umthungo wokunamathisela uqhume. Izimo ezinconyiwe zokwakha yilezi: izinga lokushisa le-ambient eliphakathi kuka-15 ℃ no-40 ℃, umswakama ohlobene>50% RH, kanye neglue ayikwazi ukusetshenziswa ngesikhathi sezulu noma iqhwa. Ngokusekelwe kokuhlangenwe nakho, lapho umswakama ohlobene komoya uphansi (umswakama uzungeza cishe u-30% RH isikhathi eside), noma kunomehluko omkhulu wezinga lokushisa phakathi kwasekuseni nakusihlwa, izinga lokushisa phakathi nosuku lingase libe cishe ku-20 ℃ (uma Isimo sezulu libalele, izinga lokushisa lamaphaneli e-aluminium elichayeke elangeni lingafinyelela ku-60-70 ℃), kodwa izinga lokushisa ebusuku lingama-degree Celsius ambalwa, ngakho-ke ukugoqana kokunamathela odongeni lwamakhethini ivame kakhulu. Ikakhulukazi ezindongeni zamakhethini e-aluminium anama-coefficients omugqa wokunweba aphezulu kanye nokuguqulwa kwezinga lokushisa okubalulekile.
D. Impahla yephaneli:
Ipuleti le-aluminium liyinto yephaneli evamile ene-coefficient ephezulu yokunwetshwa okushisayo, futhi i-coefficient yayo yomugqa yokwandisa izikhathi ezingu-2-3 kunengilazi. Ngakho-ke, amapuleti e-aluminium anobukhulu obufanayo anokwanda okukhulu kokushisa kanye nokuwohloka kokuncipha kunengilazi, futhi athambekele kakhulu ekunyakazeni okukhulu okushisayo nokuqhuma ngenxa yokushintsha kwezinga lokushisa phakathi kwemini nobusuku. Uma umkhulu usayizi wepuleti le-aluminium, kuba mkhulu ukuwohloka okubangelwa ukushintsha kwezinga lokushisa. Yingakho isivalo esifanayo singase sibe namaqhuqhuva lapho sisetshenziswa ezindaweni ezithile zokwakha, kuyilapho kwezinye izindawo zokwakha, ukugoqa akwenzeki. Esinye isizathu salokhu kungase kube umehluko ngobukhulu bamapaneli odonga lwamakhethini phakathi kwezindawo ezimbili zokwakha.
3. Ungavimba kanjani i-sealant ukuthi ingaqhume?
A. Khetha i-sealant enesivinini sokuphulukisa esisheshayo. Isivinini sokuphulukisa sinqunywa ikakhulukazi izici zefomula ye-sealant ngokwayo, ngaphezu kwezici zemvelo. Kunconywa ukusebenzisa imikhiqizo yenkampani yethu "yokomisa ngokushesha okusheshayo" yenkampani yethu noma ulungise isivinini sokuphulukisa ngokuhlukile endaweni ethile yokusetshenziswa ukuze kuncishiswe amathuba okuqhuma.
B. Ukukhetha isikhathi sokwakha: Uma ukuguquguquka okuhlobene (ukuguqulwa okuphelele/ububanzi obuhlangene) kukhulu kakhulu ngenxa yomswakama ophansi, umehluko wezinga lokushisa, usayizi wamalunga, njll., futhi kungakhathaliseki ukuthi iyiphi i-sealant esetshenziswayo, isaqhuma, yini kufanele kwenziwe?
I-1) Ukwakhiwa kufanele kwenziwe ngokushesha ngangokunokwenzeka ngezinsuku eziguqubele, njengoba umehluko wokushisa phakathi kwemini nobusuku mncane futhi ukuguqulwa kwe-adhesive joint kuncane, okwenza kungabi lula ukuqhuma.
I-2) Thatha izinyathelo ezifanele ze-shading, njengokusebenzisa amanetha othuli ukumboza isikafula, ukuze amaphaneli angavezwa ngokuqondile elangeni, anciphise izinga lokushisa lamaphaneli, futhi anciphise ukuguquguquka okuhlangene okubangelwa ukuhluka kwezinga lokushisa.
I-3) Khetha isikhathi esifanele sokufaka i-sealant.
C. Ukusetshenziswa kwezinto ezisekelayo ezinembobo kusiza ukujikeleza komoya futhi kusheshise isivinini sokuphulukisa se-sealant. (Ngezinye izikhathi, ngenxa yokuthi induku yegwebu ibanzi kakhulu, induku yegwebu iyacindezelwa futhi ikhubazekile ngesikhathi sokwakhiwa, okuzoholela nasekuqhumeni).
D. Faka ungqimba lwesibili lokunamathisela endaweni ehlangene. Okokuqala, sebenzisa i-concave adhesive joint, ulinde ukuthi iqine futhi ibe nokunwebeka kwezinsuku ezingu-2-3, bese usebenzisa ungqimba lwe-sealant ebusweni bayo. Le ndlela ingaqinisekisa ubushelelezi kanye ne-aesthetics ye-surface adhesive joint.
Kafushane, into ethi "bulging" ngemva kokwakhiwa kwe-sealant akuyona inkinga yekhwalithi ye-sealant, kodwa inhlanganisela yezinto ezihlukahlukene ezingathandeki. Ukukhethwa okulungile kwe-sealant kanye nezinyathelo ezisebenzayo zokuvimbela ukwakhiwa kunganciphisa kakhulu amathuba okuthi "bulging" isenzeko.
