Espesifikasyon twal may yo-espesyalman gwosè may, epesè, ak fòs rupture-direkteman detèmine itilizasyon li gen entansyon ak pèfòmans pwoteksyon. Espesifikasyon diferan yo adapte nan senaryo konstriksyon diferan; move seleksyon pa sèlman echwe pou bay pwoteksyon ki nesesè yo, men tou ka ogmante depans konstriksyon ak konpwomi bon jan kalite konstriksyon. Atik sa a esplike espesifikasyon kle yo nan twal may epi li bay direktiv seleksyon ki baze sou aplikasyon pou ede nan fè chwa ki dwat.
The core specifications are as follows: First is mesh size, the most critical parameter, categorized into fine (1–2 mm), medium (3–5 mm), and coarse (6–10 mm or larger) mesh. Second is thickness; standard thickness ranges from 0.1 to 0.3 mm, with greater thickness correlating to higher tensile strength. Third is tensile strength (measured in N/50mm); higher tensile strength yields better protective performance. Standard tensile strength is ≥1000 N/50mm for fiberglass mesh and ≥800 N/50mm for polyester mesh. Guide to Specifications and Applications: First, **fine-mesh cloth** (mesh size 1–2 mm, thickness 0.1–0.15 mm) is primarily used for fine crack prevention on interior walls-such as at drywall joints, within putty layers, and on ceilings-offering excellent adhesion and a smooth finish that hides the mesh pattern, thus meeting aesthetic requirements for interior decoration. Second, **medium-mesh cloth** (mesh size 3–5 mm, thickness 0.15–0.2 mm) is the most versatile type; suitable for exterior wall insulation, general wall crack prevention, tile installation reinforcement, and wall renovation, it balances protective performance with ease of application, making it a standard choice in construction. Third, **coarse-mesh cloth** (mesh size 6–10 mm, thickness 0.2–0.3 mm) is mainly used for foundation reinforcement, roofing protection, large-scale wall reinforcement, and outdoor ground protection; featuring high tensile strength and the ability to withstand significant stress, it is ideal for harsh outdoor environments and heavy-duty protection needs. Fourth, **special-specification mesh cloth** (mesh size >10 mm, thickness >0.3 mm) yo itilize prensipalman pou ranfòsman ak pwoteksyon gwo pwojè -echèl tankou bilding endistriyèl, pon, ak tinèl; ofri fòs rupture ekstrèmman wo, li satisfè kondisyon pwoteksyon ki pi egzijan yo.
Konsiderasyon Seleksyon: Anplis espesifikasyon, seleksyon materyèl yo ta dwe baze sou anviwònman konstriksyon (andedan/deyò, imid/sèk) ak bezwen pwoteksyon espesifik (prevansyon krak, ranfòsman estriktirèl, oswa izolasyon tèmik). Fiberglass may twal pi pito pou anviwònman deyò oswa imid, pandan y ap twal may Polyester se pi bon chwa pou aplikasyon andedan kay la oswa senaryo ki mande fleksibilite segondè. Anplis de sa, asire twal may seleksyon an konfòme ak estanda nasyonal yo konsènan mezi pèfòmans tankou fòs rupture ak rezistans korozyon.
