Makalasi a plywood ndi miyezo

Ntchito zambiri zopangira matabwa zimakhala ndi mndandanda wazinthu zomwe zimagwiritsidwa ntchito popanga plywood.Chilichonse kuyambira nyumba mpaka makabati akukhitchini mpaka ndege zimapindula pogwiritsa ntchito plywood pamapangidwe onse.Plywood imapangidwa ndi mapepala akuluakulu kapena ma veneers, omwe amaikidwa pamwamba pa wina ndi mzake, ndipo gawo lililonse limazungulira madigiri 90 molunjika ku njere zamatabwa.Zigawozi zimamangidwa pamodzi ndi zomatira ndi zomatira kuti zipange gulu lalikulu komanso lolimba.Plywood imapereka malo okulirapo kuposa kugwiritsa ntchito matabwa ochepa.Pali mitundu yambiri ya plywood, ngakhale yosatentha komanso yopanda madzi, yomwe imalimbikitsa kugwiritsidwa ntchito kwawo m'malo osiyanasiyana.Masiku ano, kusankha mankhwala oyenera kungakhale kovuta.Muyenera kudziwa mitundu, kukula, ndi makulidwe omwe angakwaniritse ntchitoyi.Komabe, mukamayendera gawo la plywood la malo ogulitsa zida zamkati, funso lodabwitsa lomwe mungafunse ndilakuti, ndi iti mwa zisankho zomwe zili zoyenera pulojekiti yanga?

Zonsezi zimachokera ku ndondomeko ya zigoli.Si matabwa onse omwe ali ofanana.Ndiko kunena kuti chilengedwe sichimatengera mitengo yofanana ndendende nthawi zonse.Kukhalapo kwa matabwa kumachitika chifukwa cha kusiyanasiyana kwa matabwa m'chilengedwe.Zinthu monga mtundu wa nthaka, mvula yambiri, ngakhalenso zachilengedwe za m’deralo zingakhudze mmene mitengo imakulira.Zotsatira zake zimakhala matabwa osiyanasiyana, kukula kwa nodule, ma nodule pafupipafupi, ndi zina zotero. Pamapeto pake, maonekedwe ndi machitidwe a mtengo amasiyana malinga ndi mtengo.Poyamba, izi zikuwoneka zosavuta kwambiri.Pali zabwino ndi zoyipa, sichoncho?Zosakwanira.Kwa mapulojekiti apadera, ngakhale otsika kwambiri angakhale ndi mtengo wapamwamba kwambiri.M'malo mwake, ndi bwino kuyankha funsoli poyang'ana zomwe zaperekedwa ndi mlingo uliwonse komanso kuti ndi mlingo uti womwe umakhala wotsika mtengo kwambiri pakugwiritsa ntchito.
Plywood grading system
Nawa magawo asanu ndi limodzi a plywood ndi momwe gawo lililonse limaperekera phindu pamapulojekiti opangira matabwa.
Plywood imagawidwa kukhala A grade, B, C, D, CDX, kapena BCX.Nthawi zambiri, mtundu wama board ozungulira umachokera ku A yabwino mpaka D woyipa kwambiri.Kuphatikiza apo, plywood nthawi zina imatha kubwera ndi magiredi awiri, monga AB kapena BB.Muzochitika izi, mlingo uliwonse umayimira mbali imodzi ya gululo.Ichi ndi chinthu chomwe chimapangidwa nthawi zonse, chifukwa mapulojekiti ambiri amangowonetsa mbali imodzi ya bolodi.Choncho, m'malo mogwiritsa ntchito matabwa apamwamba kwambiri kuti apange bolodi lonse, ndi ndalama zambiri kupanga matabwa onse kupatulapo pamwamba pa zinthu zapansi.Pankhani ya CDX ndi BCX, amagwiritsa ntchito ma veneer angapo ndi zomatira zapadera.X mu acronym awa nthawi zambiri amalakwitsa ngati kalasi yakunja, koma zikutanthauza kuti zomatira zapadera zosagwirizana ndi chinyezi zimagwiritsidwa ntchito pamapangidwe.
A-grade plywood
Mulingo woyamba komanso wapamwamba kwambiri wa plywood ndi Gulu A. Izi ndizokhudza kusankha mtundu wa bolodi.Plywood ya A-grade ndi yosalala komanso yopukutidwa, ndipo bolodi lonse lili ndi kapangidwe kabwino kambewu.Malo onse opukutidwa alibe mabowo kapena mipata, zomwe zimapangitsa kuti kalasi iyi ikhale yoyenera kwambiri kujambula.Mipando yamkati yamkati kapena makabati amapangidwa bwino kwambiri ndi kalasi iyi.

B-grade plywood
Mulingo wotsatira ndi Level B, mulingo uwu ukuyimiradi matabwa abwino kwambiri m'chilengedwe.Zosintha kapena kukonza zisanapangidwe mufakitale, matabwa ambiri nthawi zambiri amayandikira B-level.Izi ndichifukwa choti B-level imalola kuti pakhale mawonekedwe achilengedwe, timinofu tokulirapo tosakonzedwa, komanso mipata yapanthawi ndi nthawi.Lolani mfundo zotsekedwa zokhala ndi mainchesi mpaka 1 inchi.Ngati mutha kusalaza mfundo zingapo pa bolodi lonse, matabwawa akadali oyenera kupenta.Mulingo uwu umalolanso ming'alu yaying'ono komanso kusinthika kwa bolodi.Mapulogalamu ambiri amagwiritsa ntchito plywood ya B-grade, kuphatikizapo makabati, mipando yakunja, ndi mipando.Maonekedwe achilengedwe komanso apachiyambi a plywood iyi amapatsa pulojekiti iliyonse mphamvu ndi umunthu wokwanira.

C-grade plywood
Mulingo wotsatira ndi bolodi la C-level.Kalasi C, monga Kalasi B, imalola mabowo, mabowo, ndi mfundo.Lolani m'mimba mwake mpaka ½ mainchesi a tinthu tating'onoting'ono totsekeka, ndi mabowo a mfundo mpaka inchi imodzi m'mimba mwake, Pama board awa, pali malamulo ochepa ogawanitsa.M'mphepete ndi ndege sizingakhale zosalala ngati B-level.Zinthu zowonekera zitha kukhudzidwa ndi malamulo omasuka a C-grade plywood.Mapulogalamuwa amaphatikizapo kupanga mafelemu ndi sheathing.

D-grade plywood
Mulingo waukulu womaliza ndi mlingo D. Maonekedwe a matabwa a D-grade ndi okongola kwambiri, okhala ndi mainchesi mpaka ½ 2 mainchesi a nodes ndi pores, magawano akuluakulu, ndi kusinthika kwakukulu.Mapangidwe ambewu nawonso amakhala omasuka.Ngakhale kuti sichoyera kwambiri kapena chosavuta kupenta, plywood iyi sichachabechabe.Level D ikufunabe kuti bolodi lizitha kupirira kupsinjika ndi zolemetsa kuti zigwiritsidwe ntchito motetezeka pantchito zamatabwa kapena nyumba zazikulu.Zoonadi nkhuni zosafunikira sizili zoyenera ngakhale kalasi iliyonse, kotero mutha kukhala otsimikiza kuti ngakhale mtengo wotsika kwambiri uyenera kukwaniritsa zofunikira.Ntchito zambiri zamapangidwe zimagwiritsa ntchito mlingo uwu chifukwa nkhuni zidzaphimbidwa zivute zitani.Mphamvu idzapereka dongosolo lokhazikika pamtengo wotsika mtengo.

Gulu la BCX plywood
BCX plywood imakhalanso wamba mu gawo la plywood.Mulingo uwu umagwiritsa ntchito C-level wosanjikiza ndi B-level imodzi pamalo amodzi.Zomatira zomwe zimagwiritsidwa ntchito ndizopanda chinyezi.Izi zimagwiritsidwa ntchito pazinthu zakunja zomwe zimafunikirabe mawonekedwe, kuphatikiza zokutira kapena kupenta.Plywood yamtunduwu imagwiritsidwa ntchito pama projekiti monga mapanelo a khoma la nkhokwe, mapanelo amagalimoto aulimi, ndi mipanda yachinsinsi.
Tsopano popeza mwamvetsetsa mitundu yosiyanasiyana ya plywood, mutha kusankha molimba mtima mankhwala oyenera pantchito yanu.Kaya mukufuna zomalizitsa bwino zachilengedwe, zokutira zatsopano za utoto, kapena kulimba kokha, mudzadziwa giredi yomwe ili yoyenera kwa inu.
Gulu la CDX plywood
CDX plywood ndi chitsanzo chofala cha matabwa awiri.Monga momwe dzinalo likusonyezera, mbali imodzi ndi yopangidwa ndi C-grade veneer ndipo mbali inayo ndi ya D-grade veneer.Nthawi zambiri, wosanjikiza wamkati wotsalayo amapangidwa ndi D-grade veneer kuti ikhale yotsika mtengo.Zomatira za phenolic zosagwirizana ndi chinyezi zimagwiritsidwanso ntchito kuti zipititse patsogolo magwiridwe antchito m'malo achinyezi kapena achinyezi.Gulu ili ndi chisankho chabwino kwambiri chomwe chimafuna plywood yambiri, ndipo zambiri zidzaphimbidwa zivute zitani.CDX plywood imagwiritsidwa ntchito kwambiri pamakoma akunja ndi ma sheath.Malo a C-grade amapereka malo osalala omwe makontrakitala angagwiritse ntchito poika mbali zina za nyumbayo, kuphatikizapo zigawo zolimbana ndi nyengo ndi mapanelo a khoma.
