Mumwaka wekudonha nechando, sezvo hunyoro hwemhepo huri mumhepo hunodzikira uye musiyano wetembiricha pakati pemangwanani nemanheru uchiwedzera, pamusoro pemajoini anonamira egirazi keteni madziro uye aluminium pani yemaketeni madziro anozosimuka zvishoma nezvishoma uye akaremara munzvimbo dzakasiyana dzekuvaka. . Kunyangwe mamwe mapurojekiti emusuwo nemahwindo anogona kusangana nepamusoro deformation uye kubuda kwemajoini ekunamira pazuva rimwe chete kana mukati memazuva mashoma ekuisa chisimbiso. Isu tinozvidaidza kuti chiitiko che sealant bulging.
1. Chii chinonzi sealant bulging?
Iyo yekurapa maitiro eimwe chikamu chekuvaka weatherproof silicone sealant inotsamira pakuita nehunyoro mumhepo. Kana kukurumidza kurapa kwechisimbiso kuchinonoka, iyo nguva inodiwa kuti yakakwana yekurapa kudzika kwepamusoro ichave yakareba. Kana iyo pamusoro pechisimbiso isati yasimbiswa kusvika pakudzika kwakakwana, kana hupamhi hwekunamatira seam huchichinja zvakanyanya (kazhinji nekuda kwekuwedzera kwekushisa uye kupeta kwepaneti), pamusoro pemushonga wekunamatira uchakanganiswa uye usina kuenzana. Dzimwe nguva inoputika pakati pese inonamatira seam, dzimwe nguva inoramba ichiputika, uye dzimwe nguva inenge yakamonyoroka deformation. Mushure mekuporeswa kwekupedzisira, aya asina kuenzana epamusoro anonamira seams ese akasimba mukati (kwete mabhuru mabhuru), akaungana anonzi "bulging".

2. Bulging inoitika sei?
Chikonzero chakakosha chechiitiko che "bulging" ndechekuti iyo inonamira inosangana nekutamisa kwakakosha uye deformation panguva yekurapa, inova mhedzisiro yemhedzisiro yezvinhu zvakaita sekumhanya kwekuporesa kwechisimbiso, ukuru hwejointi yekunamatira, zvinhu uye saizi yepaneru, nharaunda yekuvaka, uye mhando yekuvaka. Kuti ugadzirise dambudziko rekuputika mumakumbo ekunamatira, zvakakosha kubvisa zvinhu zvisingafadzi zvinokonzera kuputika. Kune imwe purojekiti, zvinowanzo kunetsa kudzora tembiricha yemamiriro ekunze uye humidity, uye mapaneru zvinhu uye saizi, pamwe nedhizaini yejoini yekunamira, yakatemwa zvakare. Naizvozvo, kutonga kunogona kuwanikwa chete kubva kurudzi rwechisimbiso (adhesive displacement kugona uye kukurumidza kurapa) uye nharaunda tembiricha mutsauko shanduko.
A. Kugona kwekufamba kwechisimbiso:
Kune yakasarudzika madziro emadziro purojekiti, nekuda kweakamisikidzwa kukosha kwesaizi yeplate, mapaneru zvinhu mutsara wekuwedzera coefficient, uye gore negore tembiricha yekuchinja kwejira reketeni, kushomeka kwekufamba kwechisimbiso kunogona kuverengerwa zvichienderana neyakagadzika yakafararira. Kana mubatanidzwa wacho wakamanikana, chisimbiso chine hunyanzvi hwekufamba chinoda kusarudzwa kuti chisangane nezvinodiwa zvejoint deformation.
B. Kurapa kumhanya kwechisimbiso:
Parizvino, chisimbiso chinoshandiswa pakuvaka majoini muChina chakanyanya kurerekera silicone adhesive, inogona kupatsanurwa kuita oxime yekurapa mhando uye alkoxy yekurapa mhando zvichienderana nechikamu chekurapa. Iko kukurumidza kurapa kweoxime silicone adhesive inokurumidza kupfuura iyo yealkoxy silicone adhesive. Munzvimbo dzekuvaka dzine tembiricha yakaderera (4-10 ℃), kusiyana kukuru kwekushisa (≥ 15 ℃), uye kuderera kwehunyoro hunyoro (<50%), kushandiswa kweoxime silicone adhesive kunogona kugadzirisa akawanda e "bulging" matambudziko. Iyo inokurumidza kukurumidza kuporesa kukurumidza kwechisimbiso, iyo yakasimba iyo kugona kwayo kumirisana deformation panguva yekurapa; Iyo inononoka kukurumidza kurapa uye iyo yakakura kufamba uye deformation yejoinhi, zviri nyore kuti chibatanidzo chinonamira chipunduke.
C. Tembiricha uye hunyoro hwenzvimbo yekuvaka:
Imwe chete chikamu chekuvaka weatherproof silicone sealant inogona chete kurapa nekuita nehunyoro mumhepo, saka tembiricha uye hunyoro hwenzvimbo yekuvaka zvine imwe mhedzisiro pakumhanya kwayo kwekurapa. Kazhinji, tembiricha yepamusoro uye humidity zvinokonzeresa kuita nekukurumidza uye kukurumidza kurapa; Kudzikira tembiricha uye humidity zvinokonzeresa kunonoka kurapa reaction yekumhanya, zvichiita kuti zvive nyore kuti musono unonamira ufuge. Mamiriro ezvinhu akakurudzirwa ekuvaka ndeaya: tembiricha iri pakati pe15 ℃ ne40 ℃, hunyoro hwehukama> 50% RH, uye glue haigone kuiswa panguva yekunaya kwemvura kana chando. Zvichienderana neruzivo, kana hunyoro hwemhepo hukadzikira (mwando unotenderera 30% RH kwenguva yakareba), kana paine musiyano mukuru wetembiricha pakati pemangwanani nemanheru, tembiricha mukati mezuva inogona kunge iri 20 ℃ (kana Mamiriro ekunze ane zuva, tembiricha yealuminium mapaneru akaiswa kuzuva anogona kusvika 60-70 ℃), asi tembiricha yehusiku ingori madhigirii mashoma Celsius, saka kuputika kwemaketeni emadziro anonamira majoini. yakawanda. Kunyanya kune aluminium keteni madziro ane yakakwirira zvinhu linear yekuwedzera coefficients uye yakakosha tembiricha deformation.
D. Panel zvinhu:
Aluminium plate ndeye yakajairika mapaneru zvinhu zvine yakakwira coefficient yekuwedzera kupisa, uye mutsetse wayo wekuwedzera coefficient ndeye 2-3 nguva yegirazi. Naizvozvo, mahwendefa earuminiyamu ehukuru hwakafanana ane kuwedzera kwekupisa uye kutsikisa deformation pane girazi, uye anowanzo famba nekufamba kukuru kwekupisa uye kuputika nekuda kwekuchinja kwekusiyana kwekushisa pakati pemasikati neusiku. Iyo yakakura saizi yealuminium ndiro, iyo yakakura deformation inokonzerwa nekuchinja kwekushisa. Ichi ndicho chikonzero nei iyo sealant inogona kusangana nekuputira kana ichishandiswa pane dzimwe nzvimbo dzekuvaka, nepo mune dzimwe nzvimbo dzekuvaka, bulging haiitike. Chimwe chikonzero cheizvi chinogona kunge chiri mutsauko muhukuru hwemachira emadziro emaketeni pakati penzvimbo mbiri dzekuvaka.
3. Nzira yekudzivirira sei sealant kubva pakuputika?
A. Sarudza chisimbiso chine kukurumidza kupora. Iyo yekumhanyisa yekurapa inonyanya kutsanangurwa neiyo fomula maitiro echisimbiso pachayo, mukuwedzera kune zvakatipoteredza zvinhu. Zvinokurudzirwa kushandisa zvigadzirwa zvekambani yedu "yechando kukurumidza kuomeswa" kana kugadzirisa kumhanya kwekurapa kwakasiyana kune yakatarwa nharaunda yekushandiswa kudzikisa mukana wekuputika.
B. Kuvaka nguva yekusarudza: Kana iyo yehukama deformation (absolute deformation / joint width) yejojo yakakura zvikuru nekuda kwehunyoro hushoma, kusiyana kwekushisa, hukuru hwekubatana, nezvimwewo, uye zvisinei kuti chii chisimbiso chinoshandiswa, chinoramba chichiputika, chii zvinofanira kuitwa?
1) Kuvaka kunofanirwa kuitwa nekukasira pamazuva ane makore, sezvo mutsauko wekushisa pakati pemasikati neusiku uri mudiki uye deformation yejoini yekunamira idiki, zvichiita kuti isanyanya kuputika.
2) Tora matanho akakodzera emumvuri, sekushandisa mambure eguruva kuvhara scaffolding, kuitira kuti mapanera asaoneswe zvakananga kuchiedza chezuva, kuderedza tembiricha yemapanera, uye kuderedza kukanganiswa kwekubatana kunokonzerwa nekusiyana kwekushisa.
3) Sarudza nguva yakakodzera yekushandisa sealant.
C. Kushandiswa kweperforated kutsigira zvinhu kunofambisa kutenderera kwemhepo uye kunowedzera kukurumidza kuporesa kwechisimbiso. (Dzimwe nguva, nekuda kwekuti furo tsvimbo yakakura kwazvo, iyo furo tsvimbo inotsikirirwa mukati uye yakakanganiswa panguva yekuvaka, iyo inozotungamira kune bulge).
D. Isa chikamu chechipiri chekunamatira kune chibatanidzwa. Kutanga, shandisa concave adhesive joint, kumirira kuti isimbise uye ive elastic kwemazuva 2-3, wozoisa chisimbiso che sealant pamusoro payo. Iyi nzira inogona kuvimbisa kutsetseka uye aesthetics yeadhesive adhesive joint.
Muchidimbu, chiitiko che "bulging" mushure mekuvaka chisimbiso hachisi dambudziko rehutano hwechisimbiso, asi kusanganiswa kwezvinhu zvakasiyana-siyana zvisina kunaka. Kusarudzwa kwakaringana kwechisimbiso uye kunoshanda kwekudzivirira kwekuvaka matanho kunogona kuderedza zvakanyanya mukana we "bulging" kuitika.
