HS code: 44123900: Malo ena apamwamba ndi apansi amapangidwa ndi pepala la softwood plywood

Plywood iyi ndi ya kalasi I/2:

Kalasi l - imakhala ndi kukana kwamadzi, kukana madzi otentha bwino, zomatira zomwe zimagwiritsidwa ntchito ndi phenolic resin zomatira (PF), zomwe zimagwiritsidwa ntchito panja;

Kalasi II - plywood yotsimikizira madzi ndi chinyezi, zomatira zomwe zimagwiritsidwa ntchito ndi melamine-modified aldehyde resin adhesive (MUF), yomwe imatha kugwiritsidwa ntchito pazinyontho zambiri komanso panja;

Plywood yomwe imagwiritsidwa ntchito ngati konkriti imakhala ndi zabwino izi:

(1) Kutalika kwa bolodi ndi kwakukulu, kulemera kwakufa ndikopepuka, ndipo pamwamba pa bolodi ndi lathyathyathya.Izo osati kuchepetsa unsembe ntchito, kupulumutsa pa malo ntchito ndalama, komanso kuchepetsa mtengo wa zokongoletsa poyera konkire pamalo ndi mtengo akupera kutali olowa;

(2) Kulemera kwakukulu, makamaka kukana kuvala bwino pambuyo pa chithandizo chapamwamba, chomwe chingagwiritsidwe ntchito nthawi zambiri;

(3) Zinthuzo ndi zopepuka, matabwa a plywood ndi 18mm wandiweyani, ndipo kulemera kwa gawo lililonse ndi 50kg.Kuyendetsa, kuyika, kugwiritsa ntchito ndi kasamalidwe ka template ndikosavuta;

(4) Kuchita bwino kwa kutentha kwa kutentha, kungalepheretse kutentha kuti zisasinthe mofulumira, ndipo kumanga m'nyengo yozizira kumathandiza kuti kutentha kwa konkriti;

(5) macheka ndi yabwino, yosavuta pokonza mu akalumikidzidwa zosiyanasiyana zidindo;

(6) Ndikosavuta kupindika ndikupangidwa molingana ndi zosowa za polojekiti ndikugwiritsidwa ntchito ngati template yapamtunda.

(7) Zabwino kwa mawonekedwe a konkriti owoneka bwino.

Kusamala kuti mugwiritse ntchito

(1) Plywood yomwe yachitidwa ndi bolodi pamwamba iyenera kusankhidwa.

Pamene plywood yosagwiritsidwa ntchito imagwiritsidwa ntchito ngati mawonekedwe, chifukwa cha mphamvu yogwirizanitsa pakati pa simenti ndi matabwa pa mawonekedwe pakati pa plywood ndi konkire panthawi ya kuuma kwa konkire, mgwirizano pakati pa bolodi ndi konkire umalimba, ndipo bolodi n'zosavuta kuchotsedwa pamene demoulding.Ulusi wamatabwa pamwamba umang'ambika, zomwe zimakhudza ubwino wa konkire.Chodabwitsa ichi chimakula pang'onopang'ono ndi kuchuluka kwa nthawi zomwe plywood imagwiritsidwa ntchito.

Plywood itaphimbidwa ndi filimu imawonjezera kulimba kwa bolodi, imakhala ndi magwiridwe antchito abwino, ndipo imakhala yowoneka bwino komanso yosalala.Kudutsa.Silos, chimneys ndi nsanja, etc.

(2) Plywood (yomwe imadziwikanso kuti bolodi loyera kapena bolodi) popanda chithandizo chapamwamba chiyenera kuchitidwa musanagwiritse ntchito.
