OSB (Oriented Strand Board) Yakakurumbira Sayenzi

OSB (OrientedStrandBoard) imhando yehuni dzakagadzirwa dzakafanana ne particle board, nekuwedzera zvidimbu zvehuni (maflakes) mune yakananga inoumba binder yobva yadzvanya huni.
Yakagadzirwa muna 1963 naArmin Elmendorf weCalifornia. OSB inogona kunge iine nzvimbo yakakasharara uye yakasiyana-siyana, ine mitsetse yega yega inenge 2.5 cm x 15 cm (1.0 x 5.9 mukati) yakaiswa zvisina kuenzana pane imwe neimwe, uye mumhando dzakasiyana uye ukobvu.

Chinangwa cheOSB

OSB chinhu chine yakanaka mechanicha zvivakwa, zvichiita kuti ive yakanyanya kukodzera kune inotakura-kutakura maapplication mukuvaka.
Ikozvino yave kufarirwa kupfuura plywood, inoverengera makumi matanhatu nenhanhatu muzana yemusika wepasirese. Iyo inonyanya kushandiswa ndeyekusheedzera kumadziro, pasi uye matenga edenga.
Nekunze kwemadziro emadziro, mapaneru anogona kuvezwa neyakajeka chipingamupinyi kune rumwe rutivi; izvi zvinorerutsa kuisa uye kugadzirisa simba rekuita kwehamvuropu yekuvaka. OSB inoshandiswawo mukugadzira fenicha.

Kugadzirwa kweOSB Boards

Mhando dzekunamatira resins dzinoshandiswa neOSB dzinosanganisira: urea-formaldehyde (OSB mhando 1, isiri-yakarongeka, isina-mvura); isocyanate-based adhesives (kana PMDI polymethylene diphenyl diisocyanate-based) munzvimbo dzomukati dzine melamine-urea-formaldehyde kana phenol-formaldehyde Resin glue pamusoro (OSB rudzi 2, structural, pamusoro pekudzivirira mvura); phenolic resin (OSB mhando 3 uye 4, chimiro chechimiro, chemvura uye yekunze nharaunda).

Iwo maturu anoumbwa nekutsemura huni kuita mitsetse inovhenekwa uye yobva yatariswa pabhandi kana waya mesh. Makusheni anogadzirwa pamutsetse wekuumba. Iyo mapuranga emapuranga ekunze kwekunze anopindirana neaxis simba remapaneru, nepo mukati memukati wakamira. Huwandu hwematanho akaiswa hunoenderana nechikamu pakukora kwepaneru, asi inoganhurwa nemidziyo yakaiswa panzvimbo yekugadzira. Ukobvu hwematanho ega ega hunogonawo kusiyanisa kupa akasiyana akapedzwa makobvu epaneru (kazhinji, 15 cm (5.9 mu) layer inoburitsa 15 mm (0.59 mu) ukobvu hwepaneru). Meti yacho inoiswa muchitsina chekutsikirira chinopisa kudzvanya mapepa uye kuabatanidza nekuita kuti moto ushande uye kurapa resin yakaputirwa pamapepa. Iwo mapaneru ega ega anobva achekwa kubva pameti kusvika pakupedzwa saizi. Mazhinji epasi rose OSB anogadzirwa munzvimbo huru dzekugadzira muUnited States neCanada.
