Iimpawu zamandla aPhakamileyo zoRhwebo olupheleleyo lwePlywood yeBirch

Isakhono sokuThwala uMthwalo ngokuKhethekileyo kunye nokuSetyenziswa koLwakhiwo

I-plywood ye-birch epheleleyo yorhwebo ibonisa amandla amangalisayo okuthwala umthwalo odlula ngokubonakalayo izinto eziqhelekileyo zeplywood, iyenza ibe lolona khetho lukhethwayo kwizicelo zolwakhiwo olufunayo. Ulwakhiwo lobunjineli lubonisa i-100% yokwakheka kwe-birch core, ukuphelisa ukungahambelani kunye namanqaku abuthathaka axhaphake afunyanwa kwiintlobo ezixubileyo zeentlobo. Oku kuqulunqwa kwezinto ezifanayo kuqinisekisa ukuhanjiswa koxinano oluhambelanayo kuyo yonke indawo yolawulo, okukhokelela ekusebenzeni okunokuxelwa kwangaphambili kokuthwala umthwalo odibanayo okanye ogqithise ubunjineli obuchaziweyo. Isalathiso sengqolowa esitshintshileyo soluhlu ngalunye lwe-veneer ludala isakhiwo esinqamlezileyo esisasaza imithwalo ngokufanelekileyo kwiindlela ezininzi, ukuthintela ukugxininiswa kwengcinezelo yendawo enokuthi ibangele ukungaphumeleli. Iipropati zamandla okuqina orhwebo olupheleleyo lwe-birch plywood zifikelela kumanqanaba anomtsalane, kunye nexabiso lamandla e-parallel-to-grain ehlala idlula i-70 MPa kunye namandla e-perpendicular-to-grain agcina ngaphezulu kwe-40 MPa. Ezi mpawu zamandla zenza ukuba izinto eziphathekayo zikwazi ukusingatha imithwalo emikhulu ngaphandle kokufumana ukungaphumeleli kwentlekele, okwenza ukuba ifaneleke usetyenziso olusuka kwimiqadi yesakhiwo ukuya kwiipaneli ezithwala imithwalo. Isixhobo esikhethekileyo sokubamba isikhonkwane, sivavanywa ngaphezulu kwe-1,200 N amandla okurhoxisa, siqinisekisa uqhagamshelo lomatshini olukhuselekileyo olugcina ingqibelelo phantsi kweemeko zokulayisha ezinamandla. Lo msebenzi wokuqina uphezulu ubaluleke kakhulu kwizicelo apho ukungcangcazela, ukukhwela ibhayisekile okushushu, okanye ukulayisha okuphindaphindiweyo kwenzeka.

IiPropati zobuNjineli obuPhezulu kunye neeMetrikhi zokuSebenza

Iimpawu zoomatshini ze plywood birch epheleleyo yorhwebo zilawulwa ngononophelo ngeenkqubo ezichanekileyo zokuvelisa eziqinisekisa umgangatho ongaguqukiyo kunye nokusebenza. I-modulus ye-elasticity values ngokuqhelekileyo isuka kwi-10,000 ukuya kwi-12,000 MPa kwicala elihambelanayo kunye ne-8,000 ukuya kwi-10,000 MPa kwicala le-perpendicular, ukubonelela ngokuqina okufunekayo kwizicelo zesakhiwo. Lo mlinganiselo ophezulu wobunzima bobunzima wenza ukuba izinto eziphathekayo zibaluleke kakhulu kwizicelo apho ukunciphisa ukuphambuka kubaluleke kakhulu, njengeenkqubo zomgangatho, izakhiwo zeshelufu, kunye nezahlulo ezithwala imithwalo. Iimpawu zamandla okugoba kwi-plywood ye-birch epheleleyo yorhwebo ihlala idlula i-80 MPa, kunye namabakala amaninzi afumana amaxabiso angaphezu kwe-100 MPa phantsi kweemeko zovavanyo olusemgangathweni. La mandla okugoba akhethekileyo, adityaniswe nobuchule besixhobo sokugcina uzinzo lwe-dimensional phantsi kweemeko ezahlukeneyo zokusingqongileyo, zenza ukuba zilungele izicelo eziphantsi kweemeko zokulayisha ezintsonkothileyo. Ukuchasana kwezinto eziphathekayo ekungaphumeleli kokukhathala kubonakaliswe ngeemvavanyo zokulayisha i-cyclic, ebonisa ukuthotywa okuncinci kwiipropati zamandla nasemva kwamawaka emijikelezo yomthwalo.

IMfezeko yoLwakhiwo Phantsi kweeMeko eziBabekileyo

I-plywood ye-birch epheleleyo yorhwebo igcina imfezeko yolwakhiwo phantsi kweemeko ezigqithisileyo zokusingqongileyo ezinokubeka esichengeni izixhobo ezincinci.
