Kev tsim cov qhov rooj hluav taws PU kua nplaum

Lub qhov rooj hluav taws yog ib yam tshiab ntawm lub qhov rooj tsim nyob rau hauv xyoo tas los no kom tau raws li qhov xav tau ntawm kev tiv thaiv hluav taws hauv tsev.Hom qhov rooj hluav taws raug cais raws li qhov sib txawv ntawm qhov hluav taws kub tsis kam.Raws li qhov sib txawv ntawm qhov hluav taws kub tsis kam, tus txheej txheem thoob ntiaj teb (ISO) ntawm qhov rooj hluav taws tau muab faib ua peb qib: A, B, thiab C. Chav A qhov rooj hluav taws.Nws qhov hluav taws kub tsis txwv yog 1.2h, thiab nws feem ntau yog ua los ntawm steel phaj qhov rooj thiab lub tsev iav qhov rais.Kab A qhov rooj hluav taws yog Class B qhov rooj hluav taws rau lub hom phiaj tiv thaiv kev nthuav dav ntawm hluav taws thaum muaj hluav taws.Nws qhov hluav taws kub tsis txwv yog 0.9h.Nws yog ib lub qhov rooj steel tag nrho.Lub qhov rais me me qhib rau ntawm lub qhov rooj.Lub iav yog 5 hli tuab laminated iav los yog iav-resistant iav.Lub hom phiaj tseem ceeb ntawm Class B qhov rooj hluav taws yog tiv thaiv kev sib kis ntawm hluav taws ntawm qhov qhib thaum muaj hluav taws.Cov qhov rooj hluav taws ntoo uas muaj kev ua tau zoo dua tuaj yeem ncav cuag Class B qhov rooj hluav taws.Class C hluav taws qhov rooj.Nws qhov hluav taws kub tsis txwv yog 0.6h.Nws yog ib lub qhov rooj steel tag nrho.Lub qhov rais me me qhib rau ntawm lub qhov rooj.Lub iav yog 5 hli tuab laminated iav.Feem ntau qhov rooj hluav taws ntoo yog nyob rau theem no.Raws li cov khoom sib txawv.Raws li cov ntaub ntawv sib txawv, lub qhov rooj hluav taws tau muab faib ua ob hom: ntoo hluav taws qhov rooj thiab lub qhov rooj hluav taws steel.Ntoo hluav taws qhov rooj.Ntawd yog, cov xim tiv thaiv hluav taws yog siv rau saum npoo ntawm lub qhov rooj ntoo, lossis cov ntaub ntawv zoo nkauj uas muaj hluav taws kub-resistant yog siv rau veneer kom tau raws li qhov yuav tsum tau tiv thaiv hluav taws.Nws qhov hluav taws kub ua tau zoo dua me ntsis.Rau cov qhov rooj hluav taws kub, cov kua nplaum polyurethane feem ntau yog siv sab hauv los ua daim ntawv cog lus honeycomb cardboard, pob zeb wool thiab steel daim hlau ua cov fillers kom tau raws li kev tiv thaiv hluav taws.Peb lub tuam txhab Desai Chemical Trading Company yog cov chaw tsim khoom ntawm polyurethane kua nplaum.Peb tau tsim polyurethane PU kua nplaum rau yim xyoo.Peb muaj kev nplua nuj nyob hauv kev tsim cov qhov rooj steel, qhov rooj ruaj ntseg thiab cov qhov rooj ntoo.
