I-Fiberglass Mesh Engamelani ne-Alkali: Ukukhetha Isisindo kanye nosayizi we-Mesh we-EIFS kanye ne-Stucco

Izindonga ezimbili ze-stucco zingabonakala zifana ngosuku lapho i-scaffold iwela khona futhi ziziphatha ngendlela ehlukile ngokuphelele eminyakeni emithathu kamuva. Leyo eyayiqhekeka ngokuvamile yayingaphumeleli ngenxa yengubo yokuqeda - yehlulekile ngoba i-mesh ngaphakathi kwengubo eyisisekelo yayilula kakhulu kune-substrate, noma ngoba akekho owake wabuza ukuthi kusho ukuthini ngempela ukuthi "i-alkali resistant" ku-datasheet. Ukukhetha i-fiberglass mesh ye-EIFS kanye ne-stucco akukhona ukukhumbula inombolo yomlingo. Kumayelana nokufanisa inombolo eyodwa - isisindo - kanye nenombolo eyodwa - usayizi we-mesh - nodonga oluphambi kwakho, bese uqinisekisa ukuthi i-mesh izoqhubeka nokuba yi-mesh ngemva kweminyaka eyishumi ifakwe kusimende. Lo mhlahlandlela uhamba ngaleso sinqumo, bese ufunda ithebula lemininingwane elishicilelwe langempela umugqa nomugqa.

Lokho okwenziwa yi-mesh ohlelweni

Kokubili ukuhlanganiswa kwe-stucco kanye ne-EIFS, i-mesh ifakwe embozweni wesisekelo omanzi, lapho ihlinzeka khona ukuqinisa, ukumelana nokuqhekeka, kanye nokumelana ne-alkali kungqimba olubunjiwe. Lokho kuzwakala njengomsebenzi owodwa, kodwa umsebenzi uyashintsha nge-substrate.

Ku-EIFS yebhodi le-foam, i-substrate cishe ayinawo amandla ayo esakhiwo, ngakho-ke ungqimba lwe-mesh lusebenza ngempela: yisikhumba esimunca ukunyakaza kokushisa kanye nomthelela wohlelo lonke. Kukhonkrithi noma udonga, udonga seluzinzile kakade, futhi umsebenzi we-mesh uyancipha uye ekuvimbeleni ukuqhekeka kobuso ukuthi bungakhi futhi busabalale - lusabalalisa ukucindezeleka endaweni kunokubamba uhlelo ndawonye. Ngakho-ke ukugoqwa okufanayo kwe-mesh kwenza umsebenzi ohluke kakhulu kuye ngokuthi yini engemuva kwayo, yingakho ukukhetha isisindo kuqala nge-substrate, hhayi ikhathalogi.

Imibuzo emine ngaphambi kokukhetha isisindo

Phendula lokhu ngokulandelana bese ukukhetha isisindo kuyeka ukuba ukuqagela. Ngayinye ikutshela nokuthi kwenzekani uma uphambuka.

1. Iyini i-substrate, futhi inyakaza kangakanani?Ibhodi le-foam, i-gypsum sheathing, uhlaka lwezinkuni kanye nokwakhiwa kwezakhiwo konke kuhamba ngendlela ehlukile. Izinkuni zihamba kakhulu uma kunomswakama wesizini; i-foam ayinabo ukuqina kokwabelana ngomthwalo. Phendula kabi ngokuba lula kakhulu endaweni enyakazayo, bese ivuleka lapho kunezimbobo khona.

2. Ingabe i-mesh yenza umsebenzi wokwakha noma imane nje ivimbela ukuqhekeka kwendawo?Ku-foam ye-EIFS yenza umsebenzi wokwakha. Ku-masonry iyi-crack-arrestor. Ukucacisa ngokweqile udonga oluqinile lwe-masonry akuthengi lutho; ukucacisa kancane udonga lwe-EIFS kuthenga ama-callback.

3. Isisekelo kanye noboya bokugcina bujiyile kangakanani?Isiphetho esincane sokuhlobisa sizothumela i-mesh esindayo, eqinile ebusweni — ubona iphethini yegridi ngaphansi kwengubo. I-mesh exineneyo idinga i-base coat ebanzi ngokwanele ukuyithwala.

4. Lubheke ini udonga?Isimo sezulu kanye nokuhlaliswa kuphela, noma umthelela: ukuhamba ngezinyawo, izinqola, iminyango, amamitha amabili aphansi engaphambili kwesitolo. Izindawo zomthelela zidinga ukwakhiwa okunzima kunokuphathwa koqhekeko, kungakhathaliseki ukuthi insimu yodonga isebenzisani.

Amabhendi esisindo nokuthi angena kuphi

Kubo bonke abahlinzeki, iziqondiso ezishicilelwe zihlanganisa izisindo ze-mesh zibe amabhande anjengalawa. Kuphathe njengomkhuba ovamile embonini kunokuba kube yinto ejwayelekile — futhi qinisekisa njalo ngokumelene nobubanzi bangempela bomhlinzeki wakho:

Ibhendi	Ukusetshenziswa okuvamile	Amanothi
~45 g/m²	Amabhodi e-foam e-EIFS ngaphansi kokuqedwa okunciphile kokuhlobisa; isisekelo sethayela/i-mosaic	ibhande elilula kakhulu; livame kakhulu eziqondisweni zabahlinzeki ezishicilelwe zomsebenzi we-thin-coat
75–125 g/m²	ukuqinisa udonga okujwayelekile, amajazi ayisisekelo ajwayelekile	indawo yokusebenza yezinhlelo eziningi zangaphandle
145–160 g/m²	isembozo esijwayelekile sangaphandle kodonga, isisekelo se-mortar, amabhodi e-gypsum/insulation	ibhendi esetshenziswa kakhulu ye-stucco ejwayelekile kanye nomsebenzi wokwenza i-render
Isisindo esinzima	izindawo zomthelela, izingxenye zodonga olungezansi, ukunyakaza kohlaka lokhuni	kufanelane nokuvezwa, hhayi indawo yodonga

Inothi elilodwa eliqotho mayelana nebhendi elula kakhulu: abanye abaqondisi babahlinzeki batusa izisindo ezicishe zibe ngu-45 g/m² zomsebenzi we-EIFS onoboya obuncane. Ithebula lemodeli elishicilelwe yiRuifiber liqala ku-75 g/m², kuyilapho umugqa womkhiqizo ngokwawo uhlanganisa u-30–600 g/m² — ngakho-ke imininingwane elula ingumbuzo okufanele ubuze ngawo, hhayi inombolo okufanele uyicabangele kusukela kukhathalogi.

Ithebula lemininingwane elishicilelwe, lifundwe kahle

Nasi ithebula lemininingwane elishicilelwe le-mesh ye-fiberglass eguquguqukayo ye-Ruifiber, ephinde yakhiqizwa njengoba injalo ukuze ubone ukuthi ishidi ledatha langempela libukeka kanjani:

Inombolo Yento	I-Mesh (mm)	Isisindo (g/m²)	I-Tensile warp (N/20 cm)	I-Tensile weft (N/20 cm)	Ukuluka	Okuqukethwe kwe-resin (>%)
A2.5×2.5-110	2.5×2.5	110	1200	1000	I-Leno/leno	18
A2.5×2.5-125	2.5×2.5	125	1200	1400	I-Leno/leno	18
A5×5-75	5×5	75	800	800	I-Leno/leno	18
A5×5-125	5×5	125	1200	1300	I-Leno/leno	18
A5×5-145	5×5	145	1400	1500	I-Leno/leno	18
A5×5-160	4×4	160	1550	1650	I-Leno/leno	18
A5×5-160	5×5	160	1450	1600	I-Leno/leno	18

Imininingwane ephelele mayelanai-mesh ye-fiberglass eguquguqukayo ye-EIFSikhasi lomkhiqizo.

Kunezinto ezintathu okufanele uzifunde kuleli thebula ezingasoze zatshelwa ububanzi besisindo sodwa:

Amandla e-warp kanye ne-weft ahlelwe ngokwehlukana — futhi awalingani.Kumamodeli amaningana isiqondiso se-weft sithwala okungaphezu kwe-warp (A2.5×2.5-125: 1400 vs 1200; A5×5-145: 1500 vs 1400). Izindonga eziningi zakha ukucindezeleka eziqondisweni ezibikezelwayo — ngaphezulu nangaphansi kwezimbobo, emakhoneni — futhi uma iphethini yakho yokuqhekeka iqondisa, ukufanisa isiqondiso esinamandla ne-axis yokucindezeleka okuphezulu kuyindlela yokwenza ngcono yangempela, hhayi i-spec-sheet nicety.

Amandla okunamathela awalandeli isisindo ngendlela eqondile.Ukugxuma kusuka ku-75 kuya ku-110 g/m² okungaphezu kokugxuma kusuka ku-145 kuya ku-160 kusikisela — ukumboza, ubuningi bokulukwa kanye nekhwalithi yoboya konke kuhambisa inombolo. Ama-meshe amabili anesisindo esifanayo angahluka ngokufanele ngamandla, yingakho uqhathanisa amashidi edatha kunezihloko zekhathalogi.

Okuqukethwe kwe-resin kushicilelwe ku-≥18%.I-acrylic copolymer coating yiyo evikela ingilazi ku-alkalinity yesimende, kanti isisindo se-coating siyi-variable yangempela, elinganiselwe — i-mesh "ayimboziwe" ngomqondo we-binary. Iningi labaqondisi abancintisanayo likutshela ukuthi ucele idatha yokuhlola i-coating ngaphandle kokubonisa ukuthi inombolo eveziwe ibukeka kanjani; ≥18% ngesisindo yilokho lokho kudalulwa okubukeka ngakho kushidi ledatha langempela.

Usayizi we-Mesh: 5×5 vs 2.5×2.5 (kanye nohlobo lwe-4×4)

Usayizi we-mesh — imbobo ephakathi kwezintambo, ngamamilimitha — ibaluleke kakhulu njengesisindo, futhi ithebula elingenhla lithwala imindeni yomibili:

1.5×5 mmyilona thuba lokwakha elijwayelekile. Amaseli ayo amakhulu avumela i-base coat ukuthi ingene futhi idlule, okwenza kube nokunamathela okuhle kwemishini kuma-base coat anobukhulu obujwayelekile. Lona usayizi we-mesh ovame kakhulu emsebenzini we-render wangaphandle kanye ne-stucco.
2.2.5×2.5 mmumndeni omuhle kakhulu. Izimbobo eziqinile zifanelana namajazi ayisisekelo amancane kanye nokuqedwa lapho i-mesh kungafanele i-telegraph — umqondo ofanayo osunduzela ukuqedwa okunciphile ezisindweni ezilula.
3.Qaphela ubuningi, hhayi nje usayizi ojwayelekile.Qaphela imigqa emibili ye-A5×5-160: eyodwa ingu-4×4 ngo-25 mm, enye ingu-5×5 ngo-25 mm — umndeni ofanayo womkhiqizo, isisindo esifanayo esingu-160 g/m², inani elihlukile lentambo. Yingakho ama-meshe amabili "5×5" avela kubahlinzeki abahlukene engaziphatha ngendlela ehlukile: bala intambo ngo-25 mm (noma nge-intshi) bese uqhathanisa lokho, hhayi ilebula.

Amayunithi: N/20 cm, N/50 mm kanye ne-oz/yd²

Ngaphambi kokuthi ubeke amashidi amabili edatha eceleni, hlola amayunithi — yilapho ukuqhathanisa abahlinzeki bezinto ezahlukene kungahambi kahle khona buthule.

Amandla okuthamba acashunwa ngobubanzi besampula obuchaziwe. Ithebula likaRuifiber licashunwa ama-newton ngomugqa ongu-20 cm (N/20 cm). Imibiko yokuhlolwa yaseYurophu kumongo we-ETICS/EIFS ivame ukucashunwa ngo-50 mm (N/50 mm). Umphumela "we-1200 N" kumugqa ongu-20 cm kanye nomphumela "we-1200 N" kumugqa ongu-5 cm amazinga okuqinisa ahluke ngokuphelele - umugqa obanzi uthwala imicu eminingi, ngakho-ke ufunda phezulu ezintweni ezifanayo. Ungalokothi uqhathanise izinombolo ngaphandle kokwenza ububanzi bube ngokwejwayelekile.

Isisindo sinenkinga efanayo olwandle lonke: amashidi edatha e-metric asebenzisa i-g/m², izincwadi zase-US zivame ukusebenzisa ama-ounces ngeyadi lesikwele (oz/yd²). Ukuguqulwa kungu-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

Ngakho-ke uma umhlahlandlela obheke e-US uncoma "i-mesh engu-4.5 oz", lokho kungaba yi-mesh engu-150 g/m² — ehlala ebhentshini elifanayo ithebula lethu elibiza ukumbozwa kwangaphandle okujwayelekile.

"Ukumelana ne-alkali" — yini okufanele uyiqinisekise ngempela

Ishidi ledatha ngalinye le-mesh lithi alimelani ne-alkali. Isimangalo sihle kuphela njengohlelo lwengilazi nolwembozo olungemuva kwalo: usimende osemajazini esisekelo une-alkali kakhulu, futhi uhlasela i-fiber yengilazi engavikelekile ngokuhamba kwesikhathi. Ngakho-ke ukumelana ne-alkali kuvela ekuhlanganisweni kohlobo lwengilazi kanye nolwembozo lwe-polymer - yingakho ukuqinisekiswa okunenjongo kuyisilingo, hhayi ilebula.

Uma uqhathanisa abahlinzeki, cela:

Umbiko wokuhlolwa kokuguga kwe-alkali— amasampula e-mesh acwiliswa esixazululweni se-alkaline (NaOH) izinsuku ezingu-28 bese ehlolwa kabusha; ukugcinwa kwamandla ngemva kokuguga yinani elibalulekile. Ukugcinwa ngemva kokuvezwa kwe-alkaline kwezinsuku ezingu-28 kuyisilinganiso esivame ukucashunwa ekuhlolweni kwe-mesh yaseYurophu ngaphansi kwe-EN 13496, indinganiso yokuhlola esetshenziselwa ama-mesh okuqinisa ingilazi-fiber ezinhlelweni zokushisa zangaphandle. Cela umbiko ngokwawo, hhayi nje umugqa "ohlangabezana ne-EN 13496".
Uhlobo lokugqoka kanye nokuqukethwe— i-acrylic copolymer iyikhemikhali evamile; okuqukethwe okungu-≥18% wesisindo se-mesh yizinga lokudalulwa okufanele ukulindele kushidi ledatha.

Uhlobo lwengilazi— Ingilazi engu-C kanye nengilazi engu-E kuyizinto zokwakha ezijwayelekile; uma umhlinzeki ethi ingilazi ekhethekile, umbiko wokuhlola ubaluleke nakakhulu.

Umthetho osebenzayo: abahlinzeki ababili abacaphuna isisindo esifanayo nosayizi we-mesh basengahluka kakhulu uma i-mesh isichithe unyaka wonke kusimende. Izinombolo zedatha kuthebula elingenhla zichaza i-mesh ngosuku lokuqala; umbiko wokuguga uyichaza ngonyaka weshumi.

Izindawo: insimu, umthelela, amakhona

Incazelo yangempela yodonga ivame ukuhlanganisa izinhlobo ze-mesh kunokukhetha eyodwa: i-mesh enesisindo esijwayelekile kuyo yonke insimu yodonga, i-mesh enesisindo esindayo lapho kulindeleke khona ukuthinta — izingxenye ezingezansi zodonga eduze kwezindlela zokuhamba, eduze kweminyango, izitolo zezentengiselwano — kanye ne-mesh yekona eyakhiwe ngaphambilini kuwo wonke amakhona angaphandle, ngoba amakhona ayaqhekeka futhi aqhekeke ngaphezu kwezingxenye ezisicaba. Ukuxuba kuyindlela evamile, hhayi ukungaqiniseki; ukucacisa udonga lonke ngokweqile ukuze lufane nendawo yalo enobungozi obukhulu kuyimfucuza evamile.

Imibuzo Evame Ukubuzwa

Ngingasebenzisa isisindo esisodwa se-mesh odongeni lonke?

Ungakwazi, kodwa ngokuvamile kuba yimali engalungile. Sebenzisa isisindo sakho esizenzakalelayo kulo lonke insimu bese ukhuphuka ezindaweni ezithintekayo nasemakhoneni; insimu yodonga oluqinile lwesakhiwo samatshe ayidingi ukwakhiwa okufanayo nemitha engezansi yesitolo sangaphambili.

Ngidinga ukuhlangana okungakanani phakathi kwezingxenye ze-mesh?

Umkhuba ovamile ukuhlanganisa okungenani amasentimitha ambalwa emithungweni, okufakwe embotsheni yesisekelo njengayo yonke i-mesh, ngakho-ke ukuqinisa kuhlala kuqhubeka kulo lonke ijoyinti. Landela imininingwane yesistimu yakho lapho ikhona khona.

Abahlinzeki ababili bacaphuna isisindo esifanayo kanye nosayizi we-mesh — ngingawuqhathanisa kanjani?

Cela umbiko wokuhlolwa kokuguga kwe-alkali kanye nencazelo yokugqoka esikhundleni sokuqhathanisa intengo ngomgoqo ngamunye. I-gsm efanayo kanye nokuvulwa okufanayo okungasho ukuthi amandla ahlukene agcinwa kusimende - idatha yokuguga yiyo ehlukanisayo.

Yicacise odongeni, hhayi kukhathalogi

Isisindo silandela ukunyakaza kwe-substrate kanye nomthelela; usayizi we-mesh ulandela ukujiya kwejazi; izinombolo zamandla zilandela amashidi edatha ajwayelekile; kanti ukumelana ne-alkali kulandela umbiko wokuhlolwa, hhayi ilebula.Dlulisa amehlo emikhiqizweni yokuqinisa i-fiberglass kaRuifiberukuze ubone ububanzi obugcwele be-mesh — amamodeli ashicilelwe kusukela ku-75 kuya ku-160 g/m², kanye nomugqa womkhiqizo ohlanganisa u-30–600 g/m² — bese uthumela i-RFQ eqamba i-substrate yakho, ubukhulu bejazi kanye nezindawo zokuthinta ukuze isilinganiso sibuye sifane nodonga.
