Ukudla okusemathinini okune-asidi ephansi kubhekisela ekudleni okusemathinini okunevelu engu-PH enkulu kuno-4.6 nomsebenzi wamanzi omkhulu kuno-0.85 ngemva kokuba okuqukethwe kufinyelele ukulingana.Imikhiqizo enjalo kufanele ifakwe inzalo ngendlela enenani lokuvala inzalo elingaphezu kuka-4.0, njengokuvala inzalo eshisayo, izinga lokushisa ngokuvamile lidinga ukuvalwa inzalo ekushiseni okuphezulu nokucindezela okuphezulu (kanye nezinga lokushisa elingashintshi isikhathi esithile) ngaphezu kuka-100 °C.Ukudla okusemathinini okune-pH engaphansi kuka-4.6 kuwukudla okusemathinini okune-acidic.Uma ifakwe inzalo ngenxa yokushisa, izinga lokushisa ngokuvamile lidinga ukufika ku-100 ° C ethangini lamanzi.Uma i-monomer ekheniwe ingagoqwa ngesikhathi sokuvala inzalo, izinga lokushisa lamanzi lingaba ngaphansi kuka-100 ° C, futhi lokho okubizwa ngokuthi izinga lokushisa eliphansi liyamukelwa.Indlela yokuvala inzalo eqhubekayo.Amapentshisi avamile asemathinini, amawolintshi asemathinini, amaphayinaphu, njll. ayingxenye yokudla okufakwe i-asidi, futhi zonke izinhlobo zemfuyo esemathinini, izinkukhu, imikhiqizo yasemanzini nemifino esemathinini (njengobhontshisi obuluhlaza obusemathinini, ubhontshisi obusemathinini, njll.) ukudla okusemathinini ane-asidi.Amazwe amaningi nezifunda emhlabeni zinamazinga noma imithethonqubo yokucaciswa kokukhiqizwa kokudla okusemathinini.Ngo-2007, izwe lami lakhipha i-GB/T20938 2007 《Umkhuba Omuhle Wokudla Okusemathinini》, ebeka imigomo nezincazelo zamabhizinisi okudla okusemathinini, imvelo yefekthri, indawo yokusebenzela kanye nezinsiza, okokusebenza namathuluzi, ukuphathwa kwabasebenzi nokuqeqeshwa, ukulawula impahla kanye nokuphathwa, ukulawulwa kwenqubo yokucubungula, ukuphathwa kwekhwalithi, ukuphathwa kwenhlanzeko, ukugcinwa komkhiqizo oqediwe kanye nokuthuthwa, imibhalo namarekhodi, ukuphatha izikhalo kanye nokukhumbula umkhiqizo.Ngaphezu kwalokho, izidingo zobuchwepheshe zohlelo lokuvala inzalo lokudla okusemathinini okune-asidi ephansi zicaciswe ngokukhethekile.
