Ulusi wa Fiberglass Wosagonjetsedwa ndi Alkali: Kusankha Kulemera ndi Kukula kwa Ulusi wa EIFS ndi Stucco

Makoma awiri a stucco amatha kuwoneka ofanana tsiku lomwe scaffold imagwa ndipo amachita mosiyana kwambiri patatha zaka zitatu. Limene linasweka nthawi zambiri silinagwe chifukwa cha finish coat - linagwa chifukwa mesh mkati mwa base coat inali yopepuka kwambiri kuti isagwiritsidwe ntchito, kapena chifukwa palibe amene anafunsapo kuti "alkali resistant" kwenikweni imatanthauza chiyani pa datasheet. Kusankha fiberglass mesh ya EIFS ndi stucco sikutanthauza kukumbukira nambala yamatsenga. Ndikokhudza kufananiza nambala imodzi - kulemera - ndi nambala ina - kukula kwa mesh - ndi khoma lomwe lili patsogolo panu, kenako kutsimikizira kuti mesh idzakhalabe mesh patatha zaka khumi itayikidwa mu simenti. Bukuli lidutsa mu chisankho chimenecho, kenako limawerenga tebulo lenileni lofotokozera mzere ndi mzere.

Zimene maukonde amachitadi mu dongosolo

Mu ma assemblies onse a stucco ndi EIFS, maukonde amaikidwa mu wet base coat, komwe amapereka mphamvu, kukana ming'alu, ndi kukana alkali ku gawo lopangidwa. Izi zikumveka ngati ntchito imodzi, koma ntchitoyo imasintha ndi substrate.

Pa EIFS ya thovu, gawo lapansi lilibe mphamvu yomangira, kotero gawo la maukonde limagwira ntchito yeniyeni: ndi khungu lomwe limatenga kayendedwe ka kutentha ndi kukhudza dongosolo lonse. Pa konkire kapena miyala, khoma limakhala lokhazikika kale, ndipo ntchito ya maukonde imachepa kuti ilepheretse ming'alu ya pamwamba kuti isapangike ndikufalikira - imagawa kupsinjika m'malo mogwirizanitsa dongosololi. Chifukwa chake, mpukutu womwewo wa maukonde ukugwira ntchito yosiyana kwambiri kutengera zomwe zili kumbuyo kwake, ndichifukwa chake kusankha kulemera kumayamba ndi gawo lapansi, osati katalogu.

Mafunso anayi musanasankhe kulemera

Yankhani izi motsatizana ndipo kusankha kulemera sikungakhale kopeka. Chilichonse chimakuuzaninso zomwe zimachitika mukalakwitsa.

1. Kodi gawo lapansi ndi chiyani, ndipo limasuntha motani?Bolodi la thovu, gypsum sheathing, matabwa omangira ndi masonry zonse zimayenda mosiyana. Matabwa amayenda kwambiri ndi chinyezi cha nyengo; thovu silikhala lolimba kuti ligawane katundu. Yankhani molakwika mwa kukhala wopepuka kwambiri pa substrate yosuntha, ndipo imasweka pamalo pomwe maukonde amagwera.

2. Kodi ukonde ukugwira ntchito yomanga kapena ukungoletsa kusweka kwa pamwamba?Pa thovu la EIFS likugwira ntchito yomanga. Pa makoma ndi chotchingira ming'alu. Kuyika mopitirira muyeso khoma lokhazikika la makoma sikugula chilichonse; kuyika mopitirira muyeso khoma la EIFS kumagula zoyimitsa.

3. Kodi maziko ndi mapeto ake ndi okhuthala bwanji?Kukongoletsa kopyapyala kudzatulutsa ukonde wolemera komanso wolimba pamwamba pake — muwona mawonekedwe a gridi pansi pa utoto. Ubweya wokhuthala umafunika utoto wokhuthala wokwanira kunyamula.

4. Kodi khoma likuyang'ana chiyani?Nyengo ndi malo okhawo okhala, kapena kugundana: magalimoto oyenda pansi, ngolo zoyendera, zitseko, mamita awiri otsika a sitolo. Madera ogundana amafunika kumangidwa kolemera kuposa kuyang'anira ming'alu ya pamwamba, mosasamala kanthu za zomwe khoma limagwiritsa ntchito.

Mizere yolemera ndi komwe ikugwirizana

Kudzera mwa ogulitsa, mabuku ofalitsidwa amatsogolera magulu a maukonde olemera m'magulu ngati awa. Chitani izi ngati njira yodziwika bwino m'makampani osati muyezo - ndipo nthawi zonse tsimikizirani motsutsana ndi kuchuluka kwenikweni kwa ogulitsa anu:

Gulu la nyimbo	Kagwiritsidwe ntchito kawirikawiri	Zolemba
~45 g/m²	Mabodi a thovu a EIFS okhala ndi zokongoletsa zopyapyala; matailosi/nsalu yokongoletsera kumbuyo	mkanda wopepuka kwambiri; wofala m'mabuku ofotokozera ogulitsa ntchito zopyapyala
75–125 g/m²	zolimbitsa khoma zonse, zophimba maziko wamba	malo ogwirira ntchito a machitidwe ambiri akunja
145–160 g/m²	chophimba chakunja cha khoma, kumbuyo kwa matope, matabwa a gypsum/insulation	gulu logwiritsidwa ntchito kwambiri pa ntchito ya stucco ndi rendering
Wolemera kwambiri	madera okhudzidwa, zigawo za m'munsi mwa makoma, kuyenda kwa chimango cha matabwa	zogwirizana ndi mawonekedwe, osati malo a khoma

Chidziwitso chimodzi chowona mtima chokhudza gulu lopepuka kwambiri: ena otsogolera ogulitsa amalimbikitsa zolemera pafupifupi 45 g/m² pa ntchito ya EIFS yopyapyala. Gome la chitsanzo lofalitsidwa ndi Ruifiber limayamba pa 75 g/m², pomwe mzere wazinthuzo umaphimba 30–600 g/m² — kotero kufotokozera kopepuka ndi funso loti mufunse, osati nambala yoti muganizire kuchokera mu kabukhu.

Tebulo la ma specs lofalitsidwa, lowerengedwa bwino

Nayi tebulo lofalitsidwa la maukonde osinthasintha a fiberglass a Ruifiber, lopangidwanso momwe lilili kuti muwone momwe deta yeniyeni imaonekera:

Chinthu Nambala	Unyolo (mm)	Kulemera (g/m²)	Kupindika kwa ma tensile (N/20 cm)	Kukwezeka kwa ma tensile (N/20 cm)	Luki	Kuchuluka kwa utomoni (>%)

A5×5-160	5×5	160	1450	1600	Leno/leno	18

Tsatanetsatane wonse pamaukonde osinthika a fiberglass a EIFStsamba la malonda.

Zinthu zitatu zofunika kuziwerenga kuchokera patebulo ili zomwe kulemera kokha sikungakuuzeni:

Mphamvu za kupotoza ndi kupotoza zalembedwa padera — ndipo sizofanana.Mu mitundu ingapo, njira yolowera ku weft imanyamula zambiri kuposa njira yolowera ku warp (A2.5×2.5-125: 1400 vs 1200; A5×5-145: 1500 vs 1400). Makoma ambiri amakhala ndi mphamvu m'njira zodziwikiratu - pamwamba ndi pansi pa mipata, m'makona - ndipo ngati mawonekedwe anu a ming'alu ali kumbali, kufananiza njira yolimba ndi mzere wozungulira wa mphamvu ndi njira yabwino kwambiri, osati njira yodziwira bwino.

Mphamvu yokoka siitsatira kulemera molunjika.Kudumpha kuchokera pa 75 mpaka 110 g/m² kuposa kudumpha kuchokera pa 145 mpaka 160 kukusonyeza — kuphimba, kuchuluka kwa ulusi ndi mtundu wa ulusi zonse zimasuntha nambala. Ma meshes awiri omwe ali ndi kulemera komweko amatha kusiyana mphamvu, ndichifukwa chake mumayerekeza ma datasheet m'malo mwa mitu yankhani.

Zomwe zili mu resin zimafalitsidwa pa ≥18%.Chophimba cha acrylic copolymer ndicho chimateteza galasi ku alkalinity ya simenti, ndipo kulemera kwa chophimba ndi chosinthika chenicheni, choyezera - mesh si "yophimbidwa" mwanjira ya binary. Alangizi ambiri ampikisano amakuuzani kuti mupemphe deta yoyesera chophimba popanda kuwonetsa momwe nambala yowululidwa imawonekera; ≥18% potengera kulemera ndi momwe kufotokozerako kumawonekera pa datasheet yeniyeni.

Kukula kwa mauna: 5×5 vs 2.5×2.5 (ndi mtundu wa 4×4)

Kukula kwa mauna — malo otseguka pakati pa ulusi, mu mamilimita — ndi ofunika mofanana ndi kulemera, ndipo tebulo pamwambapa limanyamula mabanja onse awiri:

1.5 × 5 mmndiye malo otseguka omangira omwe amagwiritsidwa ntchito kwambiri. Maselo ake akuluakulu amalola kuti ubweya wa pansi ulowe ndikulowa, zomwe zimapangitsa kuti pakhale makoma abwino mu ubweya wapansi wokhuthala. Uwu ndiye kukula kwa maukonde komwe kumapezeka kwambiri pa ntchito yakunja yokongoletsa ndi stucco.
2.2.5×2.5 mmndi banja labwino kwambiri. Mipata yolimba imakwanira maziko opyapyala komanso malo omalizira pomwe maukonde sayenera kutumizidwa ndi telegraph - mfundo yomweyi yomwe imakankhira malo omalizira opyapyala kupita ku zolemera zopepuka.
3. Yang'anirani kuchuluka kwa zinthu, osati kukula kwake kokha.Onani mizere iwiri ya A5×5-160: imodzi ndi 4×4 pa 25 mm, inayo 5×5 pa 25 mm — banja lomwelo la zinthu, kulemera komweko kwa 160 g/m², kuchuluka kwa ulusi kosiyana. Ichi ndichifukwa chake ma meshes awiri a "5×5" ochokera kwa ogulitsa osiyanasiyana amatha kuchita mosiyana: werengani ulusi pa 25 mm (kapena pa inchi) ndikuyerekeza zimenezo, osati chizindikiro.

Mayunitsi: N/20 cm, N/50 mm ndi oz/yd²

Musanayike ma datasheet awiri pambali, yang'anani mayunitsi — apa ndi pomwe kufananiza kwa ogulitsa osiyanasiyana kumalakwika pang'ono.

Mphamvu yokoka imatchulidwa pa mulifupi wodziwika bwino wa chitsanzo. Tebulo la Ruifiber limafotokoza ma newton pa mzere wa 20 cm (N/20 cm). Malipoti a mayeso aku Europe mu nkhani ya ETICS/EIFS nthawi zambiri amatchulidwa pa 50 mm (N/50 mm). Zotsatira za "1200 N" pa mzere wa 20 cm ndi zotsatira za "1200 N" pa mzere wa 5 cm ndi milingo yosiyana kwambiri yolimbikitsira - mzere wokulirapo umakhala ndi ulusi wambiri, kotero umawerenga mokweza pazinthu zomwezo. Musayerekeze manambala popanda kusintha m'lifupi.

Kulemera kuli ndi vuto lomweli m'nyanja zonse: ma datasheet a metric amagwiritsa ntchito g/m², mabuku aku US nthawi zambiri amagwiritsa ntchito ma ounces pa sikweyadi imodzi (oz/yd²). Kusintha kwake ndi 1 oz/yd² ≈ 33.9 g/m²:

oz/yd²	≈ g/m²
1.3	45
2.2	75
3.2	110
4.3	145
4.7	160

Kotero pamene buku lotsogolera ku US likulangiza "maunyolo a 4.5 oz", zimenezo ndi pafupifupi maunyolo a 150 g/m² — omwe ali mu mzere womwewo tebulo lathu limatcha kuphimba kwakunja kokhazikika.

"Kulimbana ndi alkali" - zomwe muyenera kutsimikiziradi

Chikalata chilichonse cha mesh chimanena kuti sichili ndi alkali. Chimenechi ndi chabwino ngati makina agalasi ndi zokutira kumbuyo kwake: simenti yomwe ili mu maziko ake ndi ya alkali kwambiri, ndipo imalimbana ndi ulusi wagalasi wosatetezedwa pakapita nthawi. Chifukwa chake, kukana kwa alkali kumachokera ku kuphatikiza kwa mtundu wagalasi ndi zokutira za polima - ndichifukwa chake kutsimikizira kofunikira ndi mayeso, osati chizindikiro.

Poyerekeza ogulitsa, funsani:

Lipoti loyesa kukalamba kwa alkali— zitsanzo za maukonde zimanyowa mu yankho la alkaline (NaOH) kwa masiku 28 ndikuyesedwanso; mphamvu yosungira pambuyo pa kukalamba ndiyo nambala yofunika. Kusunga pambuyo pa masiku 28 a alkaline ndi muyezo wodziwika bwino mu mayeso a maukonde aku Europe motsatira EN 13496, muyezo woyesera womwe umagwiritsidwa ntchito pa maukonde olimbitsa ulusi wagalasi m'makina oteteza kutentha akunja. Funsani lipotilo lokha, osati mzere "wokwaniritsa EN 13496" wokha.
Mtundu wa zokutira ndi zomwe zili mkati mwake— acrylic copolymer ndiye mankhwala odziwika bwino; kuchuluka kwa maukonde ≥18% ndi mulingo wowululidwa womwe muyenera kuyembekezera pa datasheet.

Mtundu wagalasi— C-glass ndi E-glass ndi ma meshes omangira omwe amagwiritsidwa ntchito nthawi zonse; ngati wogulitsa akufuna galasi lapadera, lipoti la mayesolo ndilofunika kwambiri.

Lamulo lothandiza: ogulitsa awiri omwe akugwiritsa ntchito kulemera kofanana ndi kukula kwa mauna akhoza kusiyana kwambiri mauna akatha chaka chimodzi mu simenti. Manambala a deta omwe ali patebulo pamwambapa akufotokoza mauna pa tsiku loyamba; lipoti la ukalamba limafotokoza zauna mu chaka cha khumi.

Magawo: munda, impact, ngodya

Makhalidwe enieni a khoma nthawi zambiri amasakaniza mitundu ya maukonde m'malo mosankha imodzi: maukonde olemera wamba kudutsa khoma, maukonde olemera kwambiri komwe akuyembekezeka kugwedezeka — zigawo zapansi pa khoma pafupi ndi njira zoyendera, mozungulira zitseko, m'masitolo ogulitsa — ndi maukonde amakona omwe adapangidwa kale pakona iliyonse yakunja, chifukwa ngodya zimasweka ndikusweka kuposa zigawo zathyathyathya. Kusakaniza ndichizolowezi, osati kusaganiza bwino; kuyika khoma lonse mopitirira muyeso kuti ligwirizane ndi malo ake oopsa kwambiri ndi zinyalala zachizolowezi.
