Gulu la thovu la PVC lili ndi zabwino zambiri, ndipo limawonedwa ngati "m'malo mwazinthu zamatabwa" zakunja.Magwiridwe azinthu amasiyananso malinga ndi malo osiyanasiyana ogwiritsira ntchito.Mwachitsanzo, "PVC board yapakhomo" imapereka chidwi kwambiri pachitetezo ndi chitetezo cha chilengedwe, magwiridwe antchito komanso magwiridwe antchito apadera a chilengedwe, pomwe "bodi la PVC lazamalonda" limayang'ana kwambiri kukhazikika, ntchito zachuma, kuyeretsa ndi kukonza magwiridwe antchito.Pali kusamvana kutatu pakumvetsetsa komwe anthu amamvetsetsa za bolodi la thovu la PVC:
1. Cholepheretsa moto sichimayaka;
Anthu ena amafunika kugwiritsa ntchito chowunikira kuti awotche bolodi la thovu la PVC kuti awone ngati lingawotchedwe.Uku ndi kusamvetsetsana kofala.Boma likufuna kuti moto wa PVC foam board ukwaniritse mulingo wa Bf1-t0.Malinga ndi muyezo wadziko lonse, zinthu zomwe sizingayaka moto zimatchedwa A, monga mwala, matailosi, etc. Zomwe zili muyeso la Bf1-t0 flame retardant standard ndi mpira wa thonje wokhala ndi mainchesi 10 mm, woviikidwa mu mowa, ndikuyika pansi pa PVC kuti itenthe mwachibadwa.Mpira wa thonje ukatenthedwa, yesani m'mimba mwake momwe mtunda wa PVC uwotchedwa, ngati zosakwana 50mm ndi Bf1-t0 retardant flame standard.
2. Kusakhala wokonda zachilengedwe ndi kusadalira “kununkhiza”;
Zida za PVC zokha zilibe formaldehyde, ndipo siziloledwa kugwiritsa ntchito formaldehyde popanga pansi pa PVC.Ma board ena apamwamba a PVC amatha kugwiritsa ntchito zida zatsopano za calcium carbonate.Zidzavulaza thupi la anthu popanda kupangitsa anthu kukhala omasuka.Idzabalalika pambuyo popumira mpweya kwa kanthawi.
3. "Kulimbana ndi abrasion" si "kukandwa ndi chida chakuthwa";
Anthu ena atafunsa za moyo wautumiki ndi kukana kwa abrasion kwa bolodi la thovu la PVC, adatulutsa zida zakuthwa monga mpeni kapena kiyi ndikukanda pansi pa PVC.Ngati pali mikwingwirima, amaganiza kuti sikutha kuvulala.M'malo mwake, mayeso amtundu wa kukana kwa abrasion a PVC pansi sikuti amangokanda pamwamba ndi chida chakuthwa, koma amatsimikiziridwa ndi bungwe loyesa dziko.
