Ingabe kukhona izikhala eminyango nasemafasiteleni ekhaya? Ingabe ziyavuza umoya nemvula?
Ingabe iminyango namafasitela ekhaya avikelwe umsindo?
Uma udla isidlo sakusihlwa emgwaqweni, ulalela ukusakazwa bukhoma ekhaya.
Ingabe inhlaka eminyango nasemafasiteleni ekhaya isiqine?
Uma uyithinta, kusala uphawu lwezinzipho?
Ingabe inhlaka ebiseminyango nasemafasiteleni ekhaya iphukile?
Lina kakhulu ngaphandle, kodwa kancane ngaphakathi?
Ingabe inhlaka eseminyango nasemafasiteleni ekhaya isishintshile umbala?
Umnyama uphenduka umpunga, ikhofi iphenduka ikhaki, okuthinta ukubukeka
Konke lokhu kuhlobene nesivalo somnyango nefasitelas!
Ukusetshenziswa okuyinhloko kwezivalo zomnyango namafasitela ukuvala phakathi kweminyango namafasitela nengilazi, kanye nokuvala ozimele bamafasitela kanye nokuvala udonga. Uma kunenkinga ngezivalo zomnyango namafasitela, ukuvala ugesi, ukuvala ukushisa, ukuvala umsindo, ukuvala amanzi kanye neminye imisebenzi yeminyango namafasitela kuzolahleka, futhi kuzokwenzeka uchungechunge lwezimo ezibalwe ngenhla.
Uma kukhulunywa ngezivalo zokuvala umnyango namafasitela, abantu abaningi bacabanga ngalokhu: Yini? Akuzona yini izivalo zokuvala ingilazi? Yebo, yizivali zengilazi ezivame ukubonakala emilonyeni yethu. Kodwa akuzona nje izivalo zokuvala ingilazi.
Isikhathi Sesayensi Esidumile
Q: Kungani ibizwa ngokuthi i-glass sealant?
A: Ngenxa yokuthi i-silicone sealant eyasungulwa esigabeni sokuqala ine-asidi futhi ingasetshenziswa kuphela ukushaya ingilazi, ngakho-ke wonke umuntu uyibiza ngokuthi i-glass sealant ngokwesiko. Abathengi abavamile abazi lutho ngeglue, ngakho wonke umuntu uqala ukuyibiza ngokuthi i-glass sealant.
Q: Kungani kungesona nje isivali sengilazi?
A: Ngoba manje ngentuthuko esheshayo yemboni yerabha ye-silicone, ama-sealant awawona nje ama-sealant ane-acidic, kodwa futhi sekuvele neqembu elisha lama-sealant e-silicone angathathi hlangothi. Siwasebenzisa eminyango nasemafasiteleni, futhi abizwa ngokuthi i-silicone door and window glue.
I-sealant yengilazi ene-asidi isetshenziswa kakhulu ekuvimbeleni amanzi nokuvala. Inkinga yayo ukuthi inezinga elithile lokugqwala, ngakho-ke izinto ezingasetshenziswa zilinganiselwe. Ngaphezu kwalokho, isikhathi sokuphila esijwayelekile siyiminyaka emi-2 kuya kwemi-3, futhi kulula ukuba buthakathaka ngemva kwalokho; i-sealant yengilazi engathathi hlangothi inezinhlobo eziningi zokusetshenziswa, ayigqwali, futhi ihlala isikhathi eside. Inkinga yayo ukuthi yelapheka kancane. Ukukhetha okukhethekile kwe-sealant kufanele kunqunywe ngokusekelwe ezimweni zangempela.
U: Ingabe isivali somnyango nefasitela siyamelana nesimo sezulu?
A: Izinhlobo zezivalo ezisetshenziswa eminyango nasemafasiteleni zifaka: i-silicone sealant, i-polyurethane sealant, i-water-based sealant kanye ne-silane-modified polyether sealant, phakathi kwazo okuthandwa kakhulu i-silicone sealant. I-silicone sealant inokumelana okuhle kakhulu nesimo sezulu, futhi amandla ayo amakhulu e-chemical bond bond aphezulu kunamandla okukhanya kwe-ultraviolet okungu-300nm, yingakho i-silicone sealant ingagcina ukusebenza okuhle ngaphansi kokukhanya kwe-ultraviolet isikhathi eside.
Thatha i-siway 666 i-silicone sealant esebenza kahle kakhulu enobungani nemvelo njengesibonelo. Okokuqala, iyi-silicone sealant engathathi hlangothi, ngakho-ke ukumelana kwayo nesimo sezulu ngokwayo kuhle kakhulu. Ngakho-ke, kungakhathaliseki ukuthi igama liphawulwe njenge-sealant engamelani nesimo sezulu, ukumelana nesimo sezulu kwe-silicone sealant akunakuphikiswa.
Indlela yokukhetha isivalo somnyango nefasitela
I-Sealant ibiza u-1-3% kuphela wezindleko eziphelele zeminyango namafasitela okonga amandla, kodwa ikhwalithi yayo ithinta ngqo ikhwalithi kanye nomphumela wokonga amandla wephrojekthi yonke, futhi ithinta ngqo okuhlangenwe nakho kwethu kokuphila. Abantu bavame ukunaka kakhulu "izinto ezinkulu" njengengilazi namaphrofayili, futhi bangazinaki izinto ezincane ze-sealant. Abantu abazi ukuthi i-sealant yomnyango namafasitela iyizinto ezibalulekile. Ukulahlekelwa amandla okubangelwa ukwehluleka kokuvalwa komnyango namafasitela kukhulu kakhulu kunokonga amandla okungatholakala ngokukhetha ingilazi namaphrofayili angcono. Ukukhuluma ngokonga amandla kanye nokuvikelwa kwemvelo esakhiweni esivuza umoya nemvula kufana nokukhuluma okungenamsebenzi.
Ukuvalwa kweminyango namafasitela okumelana nesimo sezulu nokungangeni manzi kuyiphrojekthi ehlelekile, njengezindonga zamakhethini, okuhlanganisa ukuvalwa phakathi kozimele befasitela nengilazi, ukuvalwa phakathi kwezindonga zangaphandle nozimele beminyango namafasitela, njll. Ehlobo, ilanga likhanya kakhulu futhi isimo sezulu esibi kakhulu njengeziphepho kanye neziphepho zemvula zivame ukwenzeka. Yisikhathi esivame kakhulu sezinkinga zeminyango namafasitela. Yiziphi izinkinga okufanele siziqaphele lapho sikhetha futhi sisebenzisa izivalo ze-silicone zeminyango namafasitela?
1. Khetha imikhiqizo ejwayelekile ehlangabezana nezindinganiso zikazwelonke
I-GB/T 8478-2020 "Iminyango namafasitela e-Aluminium Alloy" ibeka phambili izidingo zezinto zokuvala nokubopha iminyango namafasitela e-aluminium alloy. Ngaphezu kwalokho, i-GB/T 14683-2017 "I-Silicone kanye ne-Modified Silicone Building Sealant", i-JC/T 881-2017 "I-Sealant yama-Concrete Joints", i-JC/T 485-2007 "I-Elastic Sealant yamafasitela okwakha" kanye nezinye izindinganiso nazo zibeka izinkomba ezihambisanayo zama-sealant okwakha iminyango namafasitela.
2. Khetha uhlobo olukhulu oluthembekile
Imakethe yeglue yomnyango nefasitela ixubene, inemikhiqizo ejwayelekile kanye nemikhiqizo ekopishayo ephuma emfudlaneni ongapheli, futhi kukhona nemikhiqizo mbumbulu. Khetha umkhiqizo omkhulu ojwayelekile onamandla obuchwepheshe ukuze wenze ucwaningo lokusebenza komkhiqizo, ulawule ngokuqinile izinto zokusetshenziswa kanye nezinqubo zokukhiqiza, futhi imikhiqizo ingathunyelwa kuphela ngemva kwezingqimba zokuhlolwa, ukuze ikhwalithi iqinisekiswe.
3. Naka ukusebenza komkhiqizo endaweni ezungezile
Ngokuphathelene nokuguquguquka, okuqukethwe yi-VOC, izinsimbi ezisindayo, njll. kwe-sealant, kunzima ngabathengi ukubona noma yiziphi izinkomba ezivela kumkhiqizo ngamehlo abo angenalutho. Kunconywa ukuthi kunakwe izimfanelo zokuvikela imvelo zomkhiqizi womkhiqizo, njengokuthi ngabe uphumelele yini ohlelweni lokuphatha ikhwalithi ye-ISO9001, uhlelo lokuphatha imvelo lwe-ISO14001, uhlelo lokuphatha impilo nokuphepha emsebenzini lwe-ISO45001, nokuthi ngabe unesitifiketi sokufaneleka sokuvikela imvelo esigunyaziwe esivela eceleni.
4. Ukwakhiwa okulungile
I-silicone sealant ithintwa kakhulu yindawo ezungezile (izinga lokushisa kanye nomswakama). Indawo esetshenziswayo evamile idinga ukuthi isetshenziswe endaweni ehlanzekile enezinga lokushisa elingu-5~40℃ kanye nomswakama ohlobene ongu-40%~80%. Ngakho-ke, akukhuthazwa ukufaka inhlaka endaweni engaphezu kwebanga elingenhla.
Ngaphezu kwalokho, kubalulekile ukunaka indawo ehlanzekile neyomile yeminyango namafasitela azokwakhiwa. Ehlobo, izinga lokushisa nomswakama kuphezulu, futhi kufanele kuqashelwe ukufaka i-glue ngokushesha okukhulu (uma kudingeka i-primer, faka i-glue ngokushesha okukhulu ngemuva kokufaka i-primer), futhi ukusika kufanele kwenziwe ngokushesha okukhulu ngemuva kokuqeda. Ngemva kwalokho, kufanele kuqedwe amahora angaphezu kwe-12 ngaphansi kwezimo ezimile nezingenakucindezeleka ngokwezimo zokupholisa zemikhiqizo ehlukene.
5. Indawo yokugcina efanele
Isimo sezulu sokushisa okuphezulu kanye nomswakama ophezulu kuzofinyeza kakhulu isikhathi sokugcina umkhiqizo futhi kubangele ukuthi umkhiqizo ungasebenzi kahle ngaphambi kwesikhathi. Ngakho-ke, kunconywa ukusebenzisa i-sealant ngokushesha okukhulu ngemuva kokuvula ehlobo. Ehlobo, kumanzi futhi kunemvula. Kufanele kuqashelwe ukuthi i-sealant kufanele igcinwe endaweni enomoya opholile futhi epholile enendawo ephakeme ukuvimbela i-sealant ukuthi ivezwe emvuleni noma ngisho nasekucwilisweni kwamanzi okubangelwa isimo sezulu esibi kakhulu, okuzothinta isikhathi sokuphila komkhiqizo futhi kubangele izinkinga zokuphola emaphaketheni omkhiqizo.
Abasebenzisi abaningi banenkinga yokusebenza kahle kokuvala iminyango namafasitela ekhaya, futhi umcabango wokuqala ukufaka iminyango namafasitela esikhundleni - manje sesiyazi ukuthi lokhu akudingekile ngempela. Okokuqala, hlola ngokucophelela ukuthi iglu yomnyango nefasitela iphukile, iqinile, noma ukuthi isebenza kabi yini. Uma inkinga iku-sealant, khona-ke udinga ukuyishintsha nge-silicone sealant yekhwalithi ephezulu enekhwalithi eqinisekisiwe.
