Kubva muna Zvita, kwave nekudonha kwekushisa kutenderera pasirese:
Nharaunda yeNordic: Nharaunda yeNordic yakaunza kutonhora kwakanyanya uye madutu echando muvhiki yekutanga ye2024, ine tembiricha yakaderera ye -43.6 ℃ uye -42.5 ℃ muSweden neFinland zvakateerana. Mushure mezvo, kukanganisa kwekudonha kukuru kwekushisa kwakawedzera kupararira kuWestern Europe neCentral Europe, uye United Kingdom neGermany dzakapa ziviso dzeyero yemamiriro ekunze echando.
Central neSouthern Europe: Tembiricha yepakati nekumaodzanyemba kweEurope nedzimwe nzvimbo yakaderera ne10 kusvika 15 ℃, uye tembiricha munzvimbo dzakakwirira-dzemakomo yakadzikira ne15 kusvika 20 ℃. Tembiricha mune dzimwe nzvimbo dzokuchamhembe kweGermany, kumaodzanyemba kwePoland, kumabvazuva kweCzech Republic, kuchamhembe kweSlovakia, uye nechepakati peRomania yakaderera zvikuru.
Zvikamu zveChina: Tembiricha munzvimbo zhinji dzeNortheast China, maodzanyemba kwakadziva kumabvazuva kweChina, nechepakati nekumaodzanyemba kweSouth China, uye maodzanyemba kwakadziva kumabvazuva kweSouthwest China yakadzikira kupfuura nguva imwechete yemakore apfuura.
North America: Tembiricha kuchamhembe kwakadziva kumabvazuva kweUnited States nepakati nekuchamhembe kweCanada yakadzikira ne4 kusvika 8℃, uye yakapfuura 12℃ mune dzimwe nzvimbo.
Dzimwe nzvimbo dzeAsia: Tembiricha yepakati peRussia yakaderera ne6 kusvika 10 ℃, uye yakapfuura 12 ℃ mune dzimwe nzvimbo.
Kudonha kwetembiricha kamwe kamwe nemhepo inotonhora inoungudza zvinouya pamwe chete. Sechinhu chakakosha chekubatsira chinoshandiswa zvakanyanya mukubatana nekuisa chisimbiso muminda yekuvaka maketeni madziro, magonhi nemahwindo, kushongedza kwemukati, nezvimwe.sealantsshandai nokushingaira pazvinhu zvose. Kunyangwe munguva yechando, havamboregi kushanda nesimba kuti vaparadzanise kutonhora kunze kwe "chipingamupinyi".
Tembiricha yemunguva yechando yakadzikira zvakanyanya, uye zvinotevera zvinogona kuitika:
(1) Pasi petembiricha yakaderera uye yakaderera humidity mamiriro, kukurumidza kurapa uye kubatanidza kumhanya kwesilicone structural sealants inononoka pane yakajairwa, izvo zvinozoita kuti nguva yekuchengetedza ive yakareba uye inokanganisa kuvaka.
(2) Kana tembiricha yakadzikira, kunyorova kwesilicone structural sealants uye substrate pamusoro inoderedzwa, uye panogona kunge paine imperceptible mhute kana chando pane substrate pamusoro, iyo inokanganisa kunamatira kwesilicone structural sealants kune substrate.
Zvishongo zvekuvaka chando
Saka chii chatinofanira kungwarira kuti tidzivise matambudziko ari pamusoro apa?
Parizvino, kune marudzi maviri ekuvaka silicone structural sealants anoshandiswa mukugadzira madziro emadziro: imwe ndeye-single-component silicone structural sealant, uye imwe yacho ine maviri-component silicone structural sealant. Iyo nzira yekurapa uye zvinhu zvinokanganisa kurapwa kweaya maviri marudzi esilicone structural sealants anoratidzwa mutafura pazasi.
| Chimwe chikamu | Zvikamu zviviri |
| Inopindirana nemvura mumhepo uye inoomesa zvishoma nezvishoma kubva kumusoro kusvika mukati. (Iyo yakadzika glue seam, iyo inotora nguva yakareba kuti inyatsopora) | Yakaporeswa nekuita kwechikamu A (ine mvura shoma), chikamu B uye hunyoro mumhepo, pamusoro uye mukati zvinoporeswa panguva imwe chete, kukurumidza kurapa kwepamusoro kunokurumidza kupfuura kukurumidza kurapa kwemukati, kunokanganisa. saizi yeglue seam uye mamiriro ekuisa chisimbiso) |
| Iyo yekumhanyisa yekurapa inononoka kupfuura iyo yezvikamu zviviri, iyo yekumhanyisa haigone kuchinjika, uye inokanganiswa nyore ne ambient tembiricha uye humidity. Kazhinji, kana tembiricha yadzikira, inononoka kuita kukurumidza; kudzikisa hunyoro, kunonokesa kukurumidza kwekuita. | Kukurumidza kuporesa kunokurumidza, uye kukurumidza kunogona kugadziriswa nehuwandu hwechikamu B. Haina kunyanya kukanganiswa nehunyoro hwepakati uye inonyanya kukanganiswa nekushisa. Kazhinji, kana tembiricha yadzikira, inononoka kurapwa. |
Zvinoenderana neChikamu 9.1 cheJGJ 102-2013 "Zveunyanzvi Zvekuita zveGlass Curtain Wall Engineering", jekiseni resilicone structural sealant rinofanirwa kuitwa pasi pemamiriro ekushisa uye hunyoro hunoenderana nezvinodiwa zvechigadzirwa. Semuyenzaniso, zvinodiwa zvezvakatipoteredza pakushandisa siway silicone structural sealant zvigadzirwa ndezvi: nharaunda yakachena ine tembiricha ye10 ℃ kusvika 40 ℃ uye hunyoro hunoenderana ne40% kusvika 80%, uye kudzivirira kuvaka mukunaya uye kune chando.
Mukuvaka kwechando, kuve nechokwadi chekuti tembiricha yekuvaka haina kuderera kupfuura 10 ℃, matanho akakodzera ekupisa anofanira kutorwa. Kana mushandisi achida kuvaka munzvimbo yakadzikira zvishoma pane 10 ℃ nekuda kwemamiriro ezvinhu akasarudzika, zvinokurudzirwa kutanga waitisa diki-scale glue bvunzo uye peeling adhesion bvunzo kuratidza kuti kurapa uye kubatanidza mhedzisiro yesilicone sealant yakanaka, uye zvakakodzera kuwedzera nguva yekuchengetedza maererano nemamiriro acho ezvinhu. Kana zvichidikanwa, funga kushandisa xylene kuchenesa nekuisa primer kusimudzira kukurumidza kubatanidza uye kuderedza njodzi yekusabatana zvakanaka nekuda kwekuderera kwekushisa.
Countermeasures yekunonoka kurapwa
① Tora matanho ekudziya akakodzera;
② Zviviri-zvikamu sealant zvinofanirwa kutanga zvaedzwa kuti zvityoke kuti zvione chiyero chakakodzera chekusanganisa;
③ Single-component sealant inoda kuongororwa nguva yekuomeswa kwepamusoro kuona kana ichigona kurapwa munzvimbo ino;
④ Inokurudzirwa kuwedzera nguva yekurapa mushure mekunamatira kuti ive nechokwadi chekuti sealant ine yakakwana yekurapa uye yekurapa nguva.
Matanho ekukanganisa kwekubatana
① Muedzo wekunamatira unofanirwa kuitwa pachine nguva isati yavakwa, uye kuvaka kunofanirwa kuitwa zvakanyatsoenderana nenzira inokurudzirwa nebvunzo yekunamatira.
② Kana zvichidikanwa, funga kushandisa xylene yekuchenesa nekuisa primer kukurudzira kukurumidza kubatanidza uye kuderedza njodzi yekusabatana kwakashata kunokonzerwa nekudzikira.
③ Mushure mekunge iyo silicone structural sealant yaiswa jekiseni, nzira yekurapa inofanira kuitwa munzvimbo yakachena uye ine mhepo. Kana tembiricha uye hunyoro hwenzvimbo yekurapa zvadzikira, nguva yekurapa inoda kuwedzerwa zvakafanira. Pakati pavo, mamiriro ekurapa eiyo imwe-chikamu structural sealant ine hukama hwakakosha nenguva yekurapa. Pasi penzvimbo imwe chete, iyo nguva yakareba yekurapa, inowedzera dhigirii yekurapa.
Kana zvichidikanwa, matanho anogona kutorwa kuwedzera ambient tembiricha uye humidity. Yekupedzisira rubber tapping bvunzo inofanirwa kushandiswa sehwaro hwekunyatsoona nguva yekuchengetedza yeyuniti yapera. Chete mushure mekupedza rabha tapping bvunzo yakwana (ona mufananidzo pazasi) inogona kuiswa nekutakurwa.
Seimwe yezvivakwa zvekuvaka, sealant inobata basa rakakosha uye inobata zvakananga basa, hupenyu hwebasa uye kukosha kwechivako, saka nzira yekuvaka inofanirwa kunyatso kudzorwa kana uchishandisa glue. Paunenge uchivaka munguva yechando uye yakaderera tembiricha mamiriro, iko kusungirirwa kwechisimbiso kunofanirwa kusimbiswa zvinoenderana nezvinodiwa kuti ive nechokwadi chekuti chisimbiso chinogona kunyatso kuvimbisa chisimbiso chisimbiso chechivakwa. Yakavambwa muna 1984, Shanghai siway, inonamatira kumoyo wehunyanzvi, yakazvipira kupa chisimbiso cheglue mhinduro dzepasi rose madziro emaketeni, girazi, gonhi nemahwindo masisitimu, glue yevagari, zvivakwa zvakafanogadzirwa uye minda yemaindasitiri senge simba, zvekufambisa, mwenje, midziyo yemagetsi, 5G kutaurirana uye zvemagetsi zvevatengi, dzimba dzakangwara, magetsi emagetsi, nezvimwewo, zvinotungamira indasitiri yakachengeteka, ine hutano, yakasvibira uye inoenderera. kuvandudza, uye kuita sarudzo yako yakakwana kubva kune zvidiki ruzivo.
Mumwaka uno unotonhora, ngatitarisirei zvese nemoyo unodziya kuti tive nechokwadi chekuvaka mhando uye mhedzisiro yesilicone structural sealants.
