We pipul dɛn aks bɔt PVC foam bod , bɔku tɛm di fɔs kwɛstyɔn nɔto kɔlɔ ɔ saiz.
Na density na.
Ɛn fɔ tɔk tru, insay di faktri, density nɔto jɔs nɔmba. I de mɔ lɛk... di we aw di bɔd de biev. Aw i de fil, aw i de kɔt, aw i de ol skru, aw i de liv na rial prɔjek dɛn.
Na Goldensign as a PVC foam board manufacturer , density na sɔntin we dɛn kin kɔntrol ɛvride. Nɔto tiori. Na prodakshɔn rialiti.
Wetin PVC fom bod density rili min?
Fɔ tɔk am simpul wan, density min ɔmɔs matirial dɛn pak insay wan kubik mita na di bod.
Lɔwa density = mɔ ɛya insay Ay density = mɔ PVC matirial kɔmprɛs
So wan PVC fom sheet na basically wan balans bitwin:
layt wet (fɔm strɔkchɔ) .
mɛkanikal trɛnk (sɔlid PVC kɔntinyu) .
Insay faktri langwej, wi kin tɔk insay difrɛn difrɛn say dɛn:
0,35 – 0,50 g/cm⊃3, ɛn di ɔda wan dɛn. → low density fom bod
0,50 – 0,65 g/cm⊃3, ɛn di ɔda wan dɛn. → standad PVC fom bod
0,65 – 0,90 g/cm⊃3, ɛn di ɔda wan dɛn. → ay density PVC fom bod
ɔp 0.90 g/cm³ → semi-rigid / nia sɔlid bɔd
Difrɛn manifakta dɛn kin kɔl dɛn difrɛn we. Sɔm se 'layt fom', sɔm se 'fri fom', sɔm se 'Celuka board'.
Na di sem famili. difrɛn we aw pipul dɛn de biev.
Aw dɛn de kɔntrol density na PVC fom bod faktri
Dis na di say we tin kin tek smɔl tɛknik, bɔt nɔto kɔmplikɛt.
Insay wan PVC fom bod faktri , dɛn kin kɔntrol di density mɔ bay:
foaming ejen rεshכn
εkstrushכn tεmprachכ
skru spid fɔ ɛkstruda
di prɛshɔn fɔ di kol sistɛm
raw PVC resin kwaliti
fila kɔntinyu (lɛk CaCO3) .
Ivin smɔl chenj dɛn kin chenj di density.
Fɔ ɛgzampul:
If fom de expand tu moch → bod bi tu layt, wik surface If fom tu low → bod de bi hevi, dia, less 'foam feel'.
So prodakshɔn na balans ɔltɛm. Nɔto jɔs 'mek am at ɔ soft'. Na tuning na.
Na dat mek difrɛn PVC fom bod manifakta dɛn kin ɔltɛm gɛt smɔl difrɛn 'fil' na dɛn bod, ivin if spɛks luk di sem pan pepa.
Low density PVC foam bod (layt tayp) .
Bɔku tɛm dɛn kin yuz dis kayn we we wet impɔtant pas trɛnk.

Bɔt na dis na di trut frɔm di faktri sayd:
Low density board nɔto fɔ ebi lod.
If yu tray fɔ yuz am lɛk wud... i nɔ go biev lɛk wud.
Sɔm kɔstɔma dɛn stil de du am, dɔn dɛn kin kam bak ɛn aks wetin mek fɔ ol skru wik.

Dis na di mɔs kɔmɔn rɛnj we bɔku faktri dɛn kin mek.
As PVC fom bod manifakta , dis na di 'standad layn'.
Wetin du?
