Ramin Fiberglass don hana ruwa shiga: Inda Yake Zuwa da Yadda Ake Zaɓar Nauyi

Bari mu fara bayyana kuskuren da aka fi sani: raga ba abu ne mai hana ruwa shiga ba. Ba ya hana ruwa shiga; membrane - murfin da aka shafa da ruwa ko kuma Layer mai hana ruwa shiga siminti - shine abin da ke rufewa. Abin da ragar ke yi shine aiki a matsayin kwarangwal mai ƙarfafawa a cikin wannan membrane: yana rarraba damuwa, yana haɗa ƙananan motsi na substrate, kuma yana riƙe da murfin da ya fashe tare a matsayin fata ɗaya mai ci gaba. Aikin kariya na tsarin har yanzu yana fitowa ne daga sinadaran membrane da kauri; ragar tana tantance ko wannan membrane ya tsira daga motsi ko ya rabu a kai.

Shi ya sa "kawai yi amfani da raga" ba takamaiman bayani ba ne. Dole ne ragar ta dace da membrane, ta yi kauri sosai don aikin, kuma an saka ta daidai - duk ukun, ko kuma ba ta ba da gudummawa ba.

Aikin da aka saba yi a cikin jagororin da tsarin shine a saka raga a cikin membrane, ba a sanya shi a saman ko a ƙarƙashinsa ba. Tsarin aiki na tsarin da aka yi amfani da ruwa:

1. Fara ko shafa gashin farko (tushe)na kayan hana ruwa shiga saman substrate ɗin da aka shirya.
2. Sanya raga a cikin rigar farko da ta jikeyayin da yake da ruwa, a matse shi a lebur sannan a yi amfani da kumfa don rufewar ta ratsa ta cikin grid ɗin - dole ne a jika ragar gaba ɗaya, ba tare da gefuna masu iyo ba.
3. Rufe gaba ɗaya da saman mayafin, don haka ragar tana cikin membrane gaba ɗaya - babu raga da za a iya gani, babu wrinkles, babu busassun tabo.

Layin raga da aka bari a fallasa ko kuma aka bar shi a bushe a ƙarƙashin gashi wanda ba zai iya riƙe shi ba zai lalace ko ya ratsa; sanwicin shine ma'anar. Haka ma'anar ta shafi turmi masu hana ruwa shiga siminti, inda aka saka raga a tsakiyar layin render.

Nauyi a cikin gram a kowace murabba'in mita shine babban maɓalli na musamman. Ka ɗauki alkaluman a matsayin al'adar masana'antu ta yau da kullun, ba ma'auni ba - nauyin da ya dace koyaushe yana bin tsarin membrane da zirga-zirgar da saman zai ɗauka.

Girman raga yana da mahimmanci tare da nauyi: ramuka masu kauri (8×8 zuwa 10×10 mm) suna barin kauri mai laushi ya ratsa sosai; grids masu kyau (kusan 5×5 mm) sun dace da siraran gashi da kuma kammalawa mai santsi.

Don sikelin, layin raga mai sassauƙa na Ruifiber ya ƙunshi 30–600 g/m² gabaɗaya (faɗinsa 500–2400 mm, a cikin yanayin laushi/daidaitacce/mai tauri), tare da samfuran da aka buga daga 75 zuwa 160 g/m² - madaurin daidaito da rufin da ke sama suna cikin kewayon da aka buga.

Misali mai aiki: gyaran baranda

A yanke shawara kan baranda ta siminti da za a sake shafa mata wani abu mai hana ruwa shiga mai sassa biyu na siminti. Tsarin ya tabbata amma gefen fale-falen, magudanar ruwa da mahaɗin bango duk suna motsawa, kuma saman da aka gama zai ga zirga-zirgar ƙafafu.

Madaurin nauyi yana nuna kewayon rufin/hanyar zirga-zirga - wanda aka fi sani da 120-160 g/m² - saboda tasirin da motsi na zafi, ba ruwa kawai ba, yana motsa takamaiman. Grid na ~5×5 mm ya dace da danko na slurry kuma yana ba saman murfin isasshen taɓawa. Tsarin shigarwa yana gudana daidai kamar yadda sandwich ɗin ya bayyana: a fara sanya raga a cikin rigar farko tare da rufewa 100 mm a kowane dinki, sannan a yanke cikakkun bayanai - ƙarin madaurin raga a kan mahaɗin bango, a kusa da magudanar ruwa, a naɗe a gefen da'ira - kafin saman murfin ya rufe komai.

Shin zai yi aiki tare da rufin ku?

Sinadarin sunadarai ne ke yanke shawarar haɗa su. Rufin hana ruwa na siminti da aka gyara da polymer yana da alkaline, wanda shine ainihin yanayin da aka gina ragar fiberglass mai jure wa alkali tare da murfin polymer - haɗin yana da na halitta kuma ana amfani da shi sosai.

Matattarar ruwa ta polyurethane da acrylic labari ne daban: ba a yi su da siminti ba, don haka ba matsalar matsalar ba ce - danshi ne. Dole ne murfin ya shiga gaba ɗaya ya kuma lulluɓe ragar don ƙarfafawa ta shiga, don haka daidaito da ƙaramin facin gwaji kafin a yi amfani da shi gaba ɗaya su ne abubuwan da suka dace.

Wani ƙarin bayanin sinadarai: murfin acrylic copolymer akan raga shine abin da ke kare gilashin daga alkalinity kuma yana haɗa laminate tare - abun da ke cikin shafi abu ne da aka ƙididdige shi (Ruifiber yana buga abun da ke cikin resin sama da 18% akan ƙayyadaddun raga). Ingancin murfin, ba kawai nau'in gilashi ba, yana yanke shawarar yadda raga ke tsufa a cikin membrane.
