Ikhowudi ye-HS: 44123900: Enye indawo ephezulu kunye nesezantsi yenziwe nge-softwood plywood sheet

Le plywood yeyeklasi I/2:

I-Class l - inokumelana nokunyuka kwamanzi, ukuxhathisa okulungileyo kwamanzi abilayo, i-adhesive esetyenziswayo yi-phenolic resin adhesive (PF), isetyenziselwa ikakhulu ngaphandle;

I-Class II - i-plywood yamanzi kunye nomswakama, i-adhesive esetyenzisiweyo yi-melamine-modified aldehyde resin adhesive (MUF), engasetyenziselwa kwiimeko eziphezulu zokufuma nangaphandle;

IPlywood esetyenziswa njengomsebenzi wekhonkrithi ineenzuzo ezilandelayo:

(1) Ububanzi bebhodi bukhulu, ubunzima obufile bulula, kwaye umphezulu webhodi usicaba.Akunakunciphisa kuphela ukufakwa komsebenzi wofakelo, gcina iindleko zabasebenzi kwisayithi, kodwa nokunciphisa iindleko zokuhombisa iindawo eziphathekayo ezibonakalayo kunye neendleko zokusila ngaphandle kwamalungu;

(2) Umthamo omkhulu wokuthwala, ngokukodwa ukuxhathisa okulungileyo kokunxiba emva konyango olungaphezulu, olunokuthi lusetyenziswe kwakhona amaxesha amaninzi;

3Ukuthuthwa, ukupakishwa, ukusetyenziswa kunye nokulawulwa kwethemplate kulula ngakumbi;

(4) Ukusebenza kakuhle kwe-thermal insulation, kunokuthintela ubushushu ukuba buguquke ngokukhawuleza, kwaye ukwakhiwa ebusika kuluncedo kwi-thermal insulation yekhonkrithi;

(5)isarha kulula, kulula ukusetyenzwa kwiimilo ezahlukeneyo zetemplates;

(6) Kukulungele ukugotywa kunye nokwakhiwa ngokweemfuno zeprojekthi kwaye isetyenziswe njenge template yomhlaba.

(7) Ilungele ukwenza umsebenzi wekhonkrithi enobuso obungenamkhethe.

Imiqathango yokusetyenziswa

(1) I-plywood eye yaphathwa ngebhodi yebhodi kufuneka ikhethwe.

Xa i-plywood engaphendulwanga isetyenziswe njenge-formwork, ngenxa yokubambisana kwamandla phakathi kwesamente kunye neenkuni kwi-interface phakathi kweplywood kunye nekhonkrithi ngexesha lenkqubo yokuqina kwekhonkrithi, ukudibanisa phakathi kwebhodi kunye nekhonkrithi kuqina ngakumbi, kwaye ibhodi kulula ukuba zisuswe xa demoulding.Imicu yomthi engaphezulu ikrazukile, echaphazela umgangatho wekhonkrithi.Esi siganeko sikhula ngokuthe ngcembe ngokunyuka kwenani lamaxesha okusetyenziswa kweplywood.

I-plywood emva kokuba igutyungelwe ngefilimu yonyusa ukuqina komphezulu webhodi, inokusebenza kakuhle kokudiliza, kwaye inembonakalo egudileyo negudileyo.Ukugqitha.Iisilo, iitshimini kunye neenqaba, njl.

(2) I-Plywood (eyaziwa nangokuthi ibhodi emhlophe okanye ibhodi ecacileyo) ngaphandle kokunyanga kwendawo kufuneka iphathwe ngaphambi kokusetyenziswa.
