Ikhodi ye-HS: 44123900: Enye indawo engaphezulu nengaphansi yenziwe ngeshidi le-softwood plywood

Le plywood ingeyekilasi I/2:

I-Class l - inokumelana okuphezulu kwamanzi, ukumelana kahle kwamanzi abilayo, i-adhesive esetshenziswa i-phenolic resin adhesive (PF), esetshenziselwa ikakhulukazi ngaphandle;

I-Class II - i-plywood engenamanzi nomswakama, i-adhesive esetshenzisiwe i-melamine-modified aldehyde resin adhesive (MUF), engasetshenziswa ezimweni zomswakama ophezulu nangaphandle;

I-plywood esetshenziswa njenge-formwork yekhonkrithi inezinzuzo ezilandelayo:

(1) Ububanzi bebhodi bukhulu, isisindo esifile silula, futhi ingaphezulu lebhodi liyisicaba.Akukwazi nje ukunciphisa umthwalo wokufaka umsebenzi, londoloza izindleko zabasebenzi esizeni, kodwa futhi kunciphise izindleko zokuhlobisa izindawo zokukhonkolo eziveziwe kanye nezindleko zokugaya amalunga;

(2) Umthamo omkhulu wokuthwala, ikakhulukazi ukumelana nokuguga okuhle ngemva kokwelashwa kwendawo, engasetshenziswa kabusha izikhathi eziningi;

(3) Impahla ilula, ipulangwe yokhuni inogqinsi oluyi-18mm, kanti isisindo endaweni ngayinye singama-50kg.Ukuthuthwa, ukupakisha, ukusetshenziswa kanye nokuphathwa kwesifanekiso kulula kakhulu;

(4) Ukusebenza okuhle kokufakwa kwe-thermal, kungavimbela izinga lokushisa ekushintsheni ngokushesha, futhi ukwakhiwa ebusika kuyasiza ekushiseni okushisayo kukakhonkolo;

(5)ukusaha kulula, kulula ukusetshenzwa kube yizifanekiso ezehlukene;

(6) Kulula ukugotshwa futhi kwakhiwe ngokuvumelana nezidingo zephrojekthi futhi kusetshenziswe njengesifanekiso esingaphezulu.

(7) Ilungele ukwenza umsebenzi wokhonkolo obukeka kahle.

Izinyathelo zokuphepha zokusetshenziswa

(1) I-plywood eye yaphathwa ngebhodi lebhodi kufanele ikhethwe.

Lapho i-plywood engasetshenziswanga isetshenziswa njenge-formwork, ngenxa yamandla okubopha phakathi kukasimende nokhuni ekuxhumaneni phakathi kwe-plywood kanye nokhonkolo ngesikhathi senqubo yokuqina kukakhonkolo, ukubopha phakathi kwebhodi nokhonkolo kuqina, futhi ibhodi kulula ukususwa lapho demoulding.Imicu yokhuni engaphezulu idabukile, okuthinta ikhwalithi yendawo ekhonkolo.Lesi simo sikhula kancane kancane ngokwanda kwenani lezikhathi okusetshenziswa ngazo i-plywood.

I-plywood ngemuva kokumbozwa ngefilimu ikhulisa ukuqina kwendawo yebhodi, inokusebenza okuhle kokudiliza, futhi inokubukeka okubushelelezi nokushelelayo.I-Overpass.Amasilo, oshimula nemibhoshongo, njll.

(2) I-plywood (eyaziwa nangokuthi ibhodi elimhlophe noma ibhodi elingenalutho) ngaphandle kokwelashwa kwendawo kufanele iphathwe ngaphambi kokusetshenziswa.
