Iglu emhlophe yePVA

Iglu yePVA sisishunqulelo sePolyvinyl acetate.Imbonakalo ngumgubo omhlophe.Luhlobo lwepolymer enyibilikayo emanzini enoluhlu olubanzi losetyenziso.Ukusebenza kwayo kuphakathi kweplastiki kunye nerabha.Ukusetyenziswa kwayo kunokwahlulwa kubini kusetyenziso olukhulu: ifayibha kunye ne-non-fiber.Ngenxa yokuba i-PVA ine-adhesion eyomeleleyo eyomeleleyo, ukuguquguquka kwefilimu, ukuguda, ukuxhathisa i-oyile, ukuxhathisa i-solvent, i-colloid ekhuselayo, umqobo wegesi, ukuxhathisa i-abrasion kunye nokuxhatshazwa kwamanzi ngonyango olukhethekileyo, ayisetyenziswanga kuphela njenge-fiber ekrwada, ikwasetyenziswa ngokubanzi kwi-fiber. ukuveliswa kweengubo, izinto zokuncamathelisa, ii-agent zokulungisa amaphepha, i-emulsifiers, i-dispersants, iifilimu kunye nezinye iimveliso, kunye nezicelo ezigubungela iingubo, ukutya, amayeza, ukwakhiwa, ukusetyenzwa kweenkuni, ukwenza iphepha, ukuprinta, ezolimo, isinyithi, imboni yemichiza yePolymer kunye namanye amashishini.
Xa kuthelekiswa ne-adhesives efanayo kwimarike, ayinayo izithako eziyityhefu ezifana ne-formaldehyde (usebenzisa i-urea-formaldehyde resin eguquliweyo okanye i-melamine resin okanye i-phenolic resin enyibilikayo emanzini enokufikelela ekukhuselweni kwendalo E2 okanye ngaphezulu. Emva kokongeza i-arhente yokunyanga kunye ne-gypsum, iya ingaba ngakumbi Ukunciphisa umxholo wamahhala we-formaldehyde wemveliso), akukho ngcoliseko kwimveliso kunye nokusetyenziswa kwendawo, ixabiso eliphantsi, inkqubo elula, isiphumo esihle sokubambisana, ukomisa ngokukhawuleza kunye nesantya sokuqina.Isetyenziselwa ukuveliswa kwepaneli esekwe ngamaplanga ngaphandle koxinzelelo olushushu kwaye ineenzuzo ezinkulu ekugcinweni kwamandla.
Abathengi abaninzi ngoku basebenzisa i-PVA emhlophe latex ukwenza i-slimes.Le yenye yezona zinto zisetyenziswa kakhulu zeglue yePVA.Kwamanye amazwe aseYurophu naseMelika, abantu abaninzi bafundisa abantwana babo imfundo yamabanga aphantsi.Impahla yayo ayinayo inetyhefu kwaye ihambelana nokusingqongileyo, ngoko akukho mfuneko yokukhathazeka malunga nokuba iglue iya kubalimaza abantwana.
