Sababtoo ah warqadda shaandhada waa in ay cadaadis saartaa wakhti dheer inta lagu jiro shaqada, waxaa lagama maarmaan ah in la helo hab lagu kordhiyo xoogga warqadda shaandhada, haddii kale si fudud ayay u qudhmi doontaa.Sidaa darteed, warqadda shaandhaynta warshadaha waa in lagu farsameeyaa habka "diridda"!

Marka loo eego habab kala duwan, waxa loo qaybin karaa laba qaybood: warqad shaandhayn adag iyo warqad shaandhayn aan la daawayn.Waraaqaha shaandhada la daaweeyay guud ahaan waxaa lagu miiray resin phenolic ah, ka dibna lagu dubay heerkul ah 150-180 darajo ilaa 15 daqiiqo si loo daweeyo xabagta oo loo kordhiyo fiiqan warqadda shaandhada.Halkan waxaa ka soo baxay "warqad filter ah oo la daweeyey!
"Waraaqda shaandhada la daajiyey" waxaa lagu daaweeyaa heerkul sare, iyo fiilooyinka warqadaha waxaa si buuxda u daboolay resin."Waraaqda shaandhada aan la daawayn" guud ahaan waxay isticmaashaa polyvinyl acetate resinka sida wakiilka uurka leh, waxaana lagu dhammeeyaa iyadoo si dabiici ah u tifqanayso ka dib rimidda.Sidaa darteed, qallafsanaanta iyo qallafsanaanta warqadda shaandheynta uma fiicna sida "warqadaha shaandhada la daweeyey".Waxaa intaa dheer, "warqad shaandho aan la daawayn" way fududahay in la nuugo biyaha oo ay qoyaan, isla mar ahaantaana, iska caabbinta heerkulka sare uma fiicna sida "warqad shaandho la daaweeyay".Qalabka labadan nooc ee waraaqaha shaandhaynta waa isku mid, laakiin habka impregnation ee soo socda ayaa gebi ahaanba ka duwan!——“Waraaqda shaandhada la daaweeyay” sida cad way ka wanaagsan tahay, biyo-mareenka badan, aashitada u adkaysta, heerkulka hoose u adkaysta, heerkulka u adkaysta, iyo alkali u adkaysta.
Filterka hawada ee Pawelson® waxa ay isticmaashaa warqad filter Ahlstrom, warqada shaandhada waxaa lagu daaweeyay heerkul sare, dhib malaha matoorkaagu waxa uu la tacaalayaa bay'ada adag, waxa ay had iyo jeer hubin doontaa in injiinkaagu leeyahay waxqabad sare.
