PVA glue ndiyo chidimbu chePolyvinyl acetate.Chitarisiko chichena hupfu.Imhando yepolymer inonyungudika nemvura ine huwandu hwakawanda hwekushandisa.Kuita kwayo kuri pakati pepurasitiki nerabha.Kushandiswa kwayo kunogona kukamurwa kuita maviri makuru mashandisirwo: faibha uye isiri-fiber.Nekuti PVA ine yakasarudzika yakasimba adhesion, firimu kuchinjika, kutsvedzereka, mafuta kuramba, solvent resistance, protective colloid, gasi barriers, abrasion resistance uye kusamira kwemvura nekurapwa kwakakosha, haingoshandiswe chete sefiber raw material, Inoshandiswawo zvakanyanya kugadzirwa kwemajasi, zvinonamira, mapepa ekugadzira mapepa, emulsifiers, dispersants, mafirimu nezvimwe zvigadzirwa, zvine maapplication anofukidza machira, chikafu, mushonga, kuvaka, kugadzira matanda, kugadzira mapepa, kudhinda, kurima, simbi, Polymer kemikari indasitiri uye mamwe maindasitiri.
Zvichienzaniswa nezvinonamira zvakafanana pamusika, haina muchetura zvinhu zvakaita se formaldehyde (uchishandisa yakagadziridzwa urea-formaldehyde resin kana melamine resin kana mvura-soluble phenolic resin inogona kusvika kuchengetedzwa kwezvakatipoteredza E2 kana kupfuura. inogona kuenderera Kuderedza iyo yemahara formaldehyde yemukati yechigadzirwa), hapana kusvibiswa kune kugadzirwa uye kushandiswa nharaunda, yakaderera mutengo, yakapusa maitiro, yakanaka bonding mhedzisiro, kukurumidza kuomesa uye kusimba kumhanya.Inoshandiswa pakugadzirwa kwemapuranga-based panel pasina kupisa kupisa uye ine zvakakosha mukuchengetedza simba.
Vazhinji vatengi ikozvino vanoshandisa PVA chena latex kugadzira slimes.Ichi zvakare chimwe chekushandisa kukuru kwePVA glue.Mune dzimwe nyika muEurope neAmerica, vanhu vakawanda vanopa vana vavo dzidzo yepuraimari.Zvinhu zvaro hazvisi-chepfu uye zvakatipoteredza, saka hapana chikonzero chekunetseka kuti glue ichakuvadza vana.
