I-Fiberglass Mesh Engamelani neAlkali: Ukukhetha Ubunzima kunye nobungakanani be-Mesh kwi-EIFS kunye ne-Stucco

Iindonga ezimbini zestucco zinokubonakala zifana ngomhla iscaffold iwela ngawo kwaye ziziphatha ngendlela eyahlukileyo emva kweminyaka emithathu. Elo laqhekeka ngesiqhelo alizange liwe ngenxa yengubo yokugqibela - lawa liwe ngenxa yokuba i-mesh ngaphakathi kwengubo esisiseko yayilula kakhulu kwi-substrate, okanye kuba akukho mntu wakha wabuza ukuba kuthetha ukuthini "ukumelana ne-alkali" kwiphepha ledatha. Ukukhetha i-fiberglass mesh ye-EIFS kunye ne-stucco akubhekiselele ekukhumbuleni inombolo yomlingo. Kumalunga nokufanisa inani elinye - ubunzima - kunye nenani elinye - ubungakanani be-mesh - nodonga oluphambi kwakho, uze uqinisekise ukuba i-mesh iya kuhlala i-mesh emva kweminyaka elishumi ifakwe kwisamente. Esi sikhokelo sihamba kweso sigqibo, size sifunde umgca wetafile yenkcazo epapashwe ngokwenene.

Oko kwenziwa yi-mesh kwinkqubo

Kwizihlanganisi ze-stucco kunye ne-EIFS, i-mesh ifakwe kwi-wet base coat, apho inika amandla, ukumelana nokuqhekeka, kunye nokumelana ne-alkali kumaleko ogqityiweyo. Oko kuvakala ngathi ngumsebenzi omnye, kodwa umsebenzi uyatshintsha nge-substrate.

Kwi-EIFS yebhodi ye-foam, i-substrate ayinawo amandla okwakha ngokwawo, ngoko ke umaleko we-mesh unomsebenzi wokwenyani: lulusu olufunxa intshukumo yobushushu kunye nefuthe kwinkqubo yonke. Kwikhonkrithi okanye udonga, udonga sele luzinzile, kwaye umsebenzi we-mesh uncipha ukuya ekuthinteleni iintanda zomphezulu ukuba zingabikho kwaye zisasazeke - isasaza uxinzelelo kwindawo ethile endaweni yokubamba inkqubo kunye. Umqulu ofanayo we-mesh ke ngoko wenza umsebenzi owahlukileyo kakhulu kuxhomekeke kwinto engasemva kwayo, yiyo loo nto ukukhetha ubunzima kuqala nge-substrate, hayi kwikhathalogu.

Imibuzo emine ngaphambi kokuba ukhethe ubunzima

Ziphendule ngokulandelelana kwazo, kwaye ukhetho lobunzima aluyi kuba yinto yokuqikelela. Ngayinye ikuxelela ukuba kwenzeka ntoni xa uphosakele.

1. Yintoni i-substrate, kwaye ishukuma kangakanani?Ibhodi yefoam, i-gypsum sheathing, i-wood framing kunye ne-masonry zonke zihamba ngokwahlukileyo. I-wood ihamba kakhulu xa kufuma ngexesha lonyaka; i-foam ayinabo ukuqina kokwabelana ngomthwalo. Phendula ngendlela engafanelekanga ngokuba lula kakhulu kwi-substrate ehambayo, kwaye ivuleke kwiindawo apho i-mesh iphela khona.

2. Ingaba i-mesh yenza umsebenzi wokwakha okanye iyamelana nokuqhekeka komphezulu?Kwi-foam ye-EIFS yenza umsebenzi wokwakha. Kwi-masonry yi-crack-arrestor. Ukucacisa ngokugqithisileyo udonga oluzinzileyo lwe-masonry akuthengi nto; ukucacisa ngaphantsi udonga lwe-EIFS kuthenga ii-callbacks.

3. Isiseko kunye noboya bokugqiba bubukhulu kangakanani?Isiphelo esincinci sokuhombisa siya kuthumela i-mesh enzima, eqinileyo kumphezulu - uyayibona ipateni yegridi phantsi kwengubo. I-mesh exineneyo ifuna i-base coat engqindilili ngokwaneleyo ukuyithwala.

4. Lujonge ntoni udonga?Imozulu kunye nokuhlaliswa kuphela, okanye impembelelo: ukuhamba ngeenyawo, iinqwelo, iingcango, iimitha ezimbini ezisezantsi zevenkile. Iindawo zempembelelo zifuna ukwakhiwa okunzima kunolawulo lokuqhekeka komhlaba, nokuba intsimi yodonga isebenzisa ntoni na.

Iibhendi zobunzima kunye nendawo ezihambelana kuyo

Kubo bonke ababoneleli, izikhokelo ezipapashiweyo zidibanisa ubunzima be-mesh zibe ziibhendi ezinje. Yiphathe njengento eqhelekileyo kushishino kunokuba ibe ngumgangatho — kwaye soloko uqinisekisa ngokuchasene noluhlu lokwenyani lomthengisi wakho:

Ibhendi	Ukusetyenziswa okuqhelekileyo	Amanqaku
~45 g/m²	Iibhodi zefoam ze-EIFS phantsi kwemigangatho emincinci yokuhombisa; ithayile/i-mosaic backing	ibhendi elula kakhulu; ixhaphakile kwizikhokelo zabathengisi ezishicilelweyo zomsebenzi onoboya obuncinci
75–125 g/m²	ukuqinisa udonga ngokubanzi, iijasi ezisisiseko ezisemgangathweni	indawo yokusebenza kwiinkqubo ezininzi zangaphandle
145–160 g/m²	isigqubuthelo esiqhelekileyo sodonga olungaphandle, umva wesamente, iibhodi zegypsum/zokufaka ubushushu	ibhendi esetyenziswa kakhulu kwi-stucco ngokubanzi kunye nomsebenzi wokwenza i-render
Ubunzima obukhulu	iindawo ezineempembelelo, iindawo ezisezantsi zodonga, ukuhamba kweefreyimu zomthi	ihambelana nokuvezwa, hayi nendawo eludongeni

Inqaku elinye elinyanisekileyo malunga nebhendi elula: ezinye izikhokelo zabathengisi zicebisa ubunzima obumalunga ne-45 g/m² kumsebenzi we-EIFS onoboya obuncinci. Itheyibhile yemodeli epapashwe yiRuifiber iqala kwi-75 g/m², ngelixa umgca wemveliso ngokwawo ugubungela i-30–600 g/m² — ngoko ke iinkcukacha ezikhaphukhaphu ngumbuzo omele ubuze ngawo, hayi inani onokulicinga kwikhathalogu.

Itheyibhile yeenkcukacha ezipapashiweyo, ifundwe kakuhle

Nantsi itheyibhile yeenkcukacha ezipapashiweyo ze-mesh ye-fiberglass eguquguqukayo yeRuifiber, ephinde yaveliswa njengoko injalo ukuze ubone ukuba i-datasheet yokwenyani ibukeka njani:

Inombolo yento	Umnatha (mm)	Ubunzima (g/m²)	I-warp ethambileyo (N/20 cm)	I-Tensile weft (N/20 cm)	Ukuluka	Umxholo weresin (>%)
A2.5×2.5-110	2.5×2.5	110	1200	1000	ILeno/leno	18
A2.5×2.5-125	2.5×2.5	125	1200	1400	ILeno/leno	18
A5×5-75	5×5	75	800	800	ILeno/leno	18
A5×5-125	5×5	125	1200	1300	ILeno/leno	18

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

Iinkcukacha ezipheleleyo malungai-mesh ye-fiberglass eguquguqukayo ye-EIFSiphepha lemveliso.

Zintathu izinto ezibalulekileyo ekufuneka uzifunde kule theyibhile, ezingasayi kuze zikuxelele uluhlu lobunzima lodwa:

Amandla e-Warp kunye ne-weft adweliswe ngokwahlukeneyo — kwaye awalingani.Kwiimodeli ezininzi, ulwalathiso lwe-weft luthwala okungaphezulu kune-warp (A2.5×2.5-125: 1400 vs 1200; A5×5-145: 1500 vs 1400). Uninzi lweendonga luphuhlisa uxinzelelo kwiindlela eziqikelelweyo — ngaphezulu nangaphantsi kwemingxuma, ecaleni kweekona — kwaye ukuba ipateni yakho yokuqhekeka ibhekiselele kwicala, ukufanisa ulwalathiso oluqinileyo kwi-axis yoxinzelelo oluphezulu kukwenza ngcono ngokwenene, kungekhona i-spec-sheet nicety.

Amandla okutsalwa awalandeleli ubunzima ngendlela ethe tye.Ukutsiba ukusuka kwi-75 ukuya kwi-110 g/m² ngaphezulu kunokutsiba ukusuka kwi-145 ukuya kwi-160 kubonisa — ukugquma, uxinano lwe-weave kunye nomgangatho wentambo zonke zishukumisa inani. Ii-meshes ezimbini ezinobunzima obufanayo zinokwahluka ngokusemthethweni ngamandla, yiyo loo nto kanye uthelekisa amaphepha edatha endaweni yezihloko zekhathalogu.

Umxholo we-resin upapashwa kwi-≥18%.I-acrylic copolymer coating yiyo ekhusela iglasi kwi-alkalinity yesamente, kwaye ubunzima be-coating yi-variable yokwenyani, elinganisiweyo — i-mesh "ayigqunywanga" ngengqiqo ye-binary. Uninzi lwezikhokelo zokhuphiswano zikuxelela ukuba ucele idatha yovavanyo lwe-coating ngaphandle kokubonisa ukuba inani elityhiliweyo libukeka njani; ≥18% ngobunzima yindlela ebonakala ngayo loo nkcazelo kwiphepha ledatha lokwenyani.

Ubungakanani be-mesh: 5×5 vs 2.5×2.5 (kunye nohlobo lwe-4×4)

Ubungakanani be-mesh — umngxuma ophakathi kweentambo, ngeemilimitha — ubaluleke kakhulu njengobunzima, kwaye itheyibhile engasentla ithwala zombini iintsapho:

1.5×5 mmyindlela evulekayo yokwakha ngokubanzi. Iiseli zayo ezinkulu zivumela isiseko sengubo singene size singene, zinika isiseko esiqinileyo esiqinileyo kwisiseko sengubo esinobukhulu obuqhelekileyo. Olu lolona bungakanani be-mesh buqhelekileyo kwi-render yangaphandle kunye nomsebenzi we-stucco.
2.2.5×2.5 mmlusapho oluhle ngakumbi. Izithuba eziqinileyo zifanelana neengubo ezisezantsi ezibhityileyo kunye neengubo ezigqityiweyo apho i-mesh akufuneki i-telegraph - ingqiqo efanayo etyhala ii-finishes ezibhityileyo ziye kwiintsimbi ezikhaphukhaphu.
3. Jonga ubuninzi, hayi ubukhulu obuqhelekileyo kuphela.Qaphela imiqolo emibini ye-A5×5-160: enye yi-4×4 count nge-25 mm, enye yi-5×5 nge-25 mm — usapho olufanayo lwemveliso, ubunzima obufanayo be-160 g/m², inani leentambo ezahlukeneyo. Yiyo loo nto ii-meshes ezimbini ze-"5×5" ezivela kubathengisi abahlukeneyo zinokuziphatha ngokwahlukileyo: bala iintambo nge-25 mm (okanye nge-intshi) kwaye uthelekise oko, hayi ilebheli.

Iiyunithi: N/20 cm, N/50 mm kunye ne-oz/yd²

Ngaphambi kokuba ubeke amaphepha edatha amabini ecaleni kwelinye, jonga iiyunithi — kulapho ukuthelekiswa kwabathengisi abahlukeneyo kuhamba khona gwenxa kancinci.

Amandla okutsalwa acatshulwa ngokobubanzi obuchaziweyo besampuli. Itheyibhile kaRuifiber icaphula ii-newtons ngomgca we-20 cm (N/20 cm). Iingxelo zovavanyo zaseYurophu kumxholo we-ETICS/EIFS zihlala zicatshulwa ngomgca we-50 mm (N/50 mm). Isiphumo "se-1200 N" kumgca we-20 cm kunye nesiphumo se-"1200 N" kumgca we-5 cm ngamanqanaba okuqinisa ahlukeneyo ngokupheleleyo - umgca obanzi uthwala imisonto emininzi, ngoko ke ufunda ngaphezulu kwinto efanayo. Ungaze uthelekise amanani ngaphandle kokulungisa ububanzi.

Ubunzima bunengxaki efanayo kuzo zonke iilwandle: amaphepha edatha e-metric asebenzisa i-g/m², uncwadi lwase-US ludla ngokusebenzisa ii-ounces ngeyadi yesikwere (oz/yd²). Ukuguqulwa yi-1 oz/yd² ≈ 33.9 g/m²:

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

Ngoko ke xa isikhokelo esijonge e-US sicebisa "i-mesh ye-4.5 oz", loo nto imalunga ne-150 g/m² mesh - ehleli kwibhendi efanayo itafile yethu ibiza ukugqunywa okuqhelekileyo kwangaphandle.

"Ukumelana ne-alkali" - yintoni ekufuneka uyiqinisekise ngokwenene

Iphepha ngalinye ledatha le-mesh lithi ayimelani ne-alkali. Ibango lilungile kuphela njengenkqubo yeglasi kunye ne-coating engasemva kwayo: isamente kwi-base coats ine-alkaline eninzi, kwaye ihlasela i-glass fiber engakhuselekanga ngokuhamba kwexesha. Ngoko ke ukumelana ne-alkali kuvela ekudibaneni kohlobo lweglasi kunye ne-polymer coating - yiyo loo nto ukuqinisekiswa okunentsingiselo kuvavanyo, kungekhona ileyibhile.

Xa uthelekisa ababoneleli, cela oku kulandelayo:

Ingxelo yovavanyo lokwaluphala kwe-alkali— iisampulu ze-mesh zifakwa kwisisombululo se-alkaline (NaOH) kangangeentsuku ezingama-28 kwaye zivavanywe kwakhona; ukugcinwa kwamandla emva kokwaluphala linani elibalulekileyo. Ukugcinwa emva kokuvezwa kwe-alkaline kwiintsuku ezingama-28 yindlela eqhelekileyo ekhankanywayo kuvavanyo lwe-mesh lwaseYurophu phantsi kwe-EN 13496, umgangatho wovavanyo osetyenziselwa i-meshes yokuqinisa i-glass-fiber kwiinkqubo zokuthintela ubushushu bangaphandle. Cela ingxelo ngokwayo, kungekhona nje umgca "ohlangabezana ne-EN 13496".
Uhlobo lokwaleka kunye nomxholo— i-acrylic copolymer yikhemistri eqhelekileyo; umxholo ≥18% wobunzima be-mesh linqanaba lokutyhilwa omele ukulindele kwiphepha ledatha.

Uhlobo lweglasi— Iglasi ye-C kunye neglasi ye-E zezona zinto ziqhelekileyo zokwakha; ukuba umthengisi ubanga iglasi ekhethekileyo, ingxelo yovavanyo ibaluleke nangakumbi.

Umthetho osebenzayo: abathengisi ababini abacaphula ubunzima obufanayo kunye nobukhulu be-mesh basenokwahluka kakhulu xa i-mesh ichithe unyaka kwisamente. Amanani edatha kwitheyibhile engentla achaza i-mesh ngosuku lokuqala; ingxelo yokuguga iyichaza kunyaka weshumi.

Iindawo: intsimi, impembelelo, iikona

Inkcazelo yokwenene yodonga idla ngokudibanisa iintlobo ze-mesh endaweni yokukhetha enye: i-mesh enobunzima obuqhelekileyo kulo lonke ibala lodonga, i-mesh enobunzima apho kulindeleke ukuba kubekho impembelelo — iindawo ezisezantsi zodonga kufutshane neendlela zokuhamba, ezijikeleze iminyango, iivenkile zorhwebo — kunye ne-mesh yekona eyenziwe kwangaphambili kuyo yonke ikona yangaphandle, kuba iikona ziyaqhekeka kwaye ziqhekeka ngaphezu kwamacandelo asicaba. Ukuxuba yinto eqhelekileyo, kungekhona ukungagqibi; ukucacisa udonga lonke ukuze luhambelane nendawo yalo enomngcipheko ophezulu yinkunkuma eqhelekileyo.
