I-Polyvinyl yotywala yipolymer e-soluble enamanzi, enokunyibilika kwamanzi, ukwenza ifilimu, ukubambelela kunye ne-emulsification, kodwa zimbalwa iikhompawundi eziphilayo ezinokuyinyibilikisa, iikhompawundi zepolyol ezinje nge-glycerol, i-ethylene glycol kunye nobunzima beemolekyuli eziphantsi zepolyethylene glycol, amide, triethanolamine ityuwa, i-dimethyl sulfoxide, njl., kwezi nyibilikisi zingasentla, nyibilikisa inani elincinci le-polyvinyl yotywala nayo ifuna ukufudunyezwa. Isisombululo se-Polyvinyl yotywala esine-benzyl yotywala kunye nomxube we-acid wokungqinelana okungalunganga, ukugcekwa ngokulula, kwaye kwangaxeshanye ne-methyl cellulose, i-hydroxyethyl cellulose solubility yamahlwempu, kodwa i-carboxy methyl cellulose solubility ingcono.

Polyacrylamide yi yomgama Polymer-enyibilikayo amanzi, yona kunye neziphumo zayo zingasetyenziswa njenge flocculants, thickeners, iphepha enhancers kunye retarders, njl .. Njengoko polyacrylamide chain molekyuli iqulathe iqela amide, oko luphawulwa hydrophilicity eliphezulu, kodwa ayinyibiliki kakhulu izisombululo ze-organic, ezinje nge-methanol, i-ethanol, i-acetone, i-ether, ii-hydrocarbon ze-aliphatic kunye neehydrocarbon ezinamakha. Isisombululo seMethyl cellulose elulwelo kuhlobo lwe-benzyl yotywala ye-asidi ezinzile, kwaye izinto ezahlukeneyo ezinokunyibilika emanzini zinokudityaniswa okuhle. Isixa se-viscosity kuxhomekeke kwiimfuno zokwakha, kodwa isiphumo sokuqina asilingani ngokuthe ngqo nesixa, kunye nokunyuka kwenani lokongezwa, isisombululo esinamanzi ngokuthe ngcembe sinciphisa ubushushu be-gelation. Uhlobo lweBenzaldehyde alunakonyuswa ngokudibanisa i-methyl cellulose ukufezekisa isiphumo se-viscosity.

5) Umhlwa Inhibitor

Ukuthintela ukubola kwe-substrate (ngakumbi i-magnesium kunye ne-aluminium), isixa esithile se-corrosion inhibitor kufuneka songezwe. Ukubola yingxaki engenakuhoywa kwinkqubo yokwenyani yemveliso, kwaye izinto eziphathwe ngepeyinti kufuneka zihlanjwe kwaye zomiswe ngamanzi okanye zihlanjwe nge-rosin nepetroli ngexesha elifanelekileyo ukuqinisekisa ukuba isinyithi kunye nezinye izinto azonakalisi.

6) Inhibitors eziguqukayo

Ngokubanzi, izinto ezinokungena ngokulula kulula ukuzinyusa, ke ukuze kuthintelwe i-volatilization yeemolekyuli eziphambili zesinyibilikisi, isixa esithile se-volatilization inhibitor kufuneka songezwe kwipeyinti yokupeyinta ukunciphisa i-volatilization yeemolekyuli zesinyibilikisi kwinkqubo yemveliso , ukuthuthwa, ukugcinwa kunye nokusetyenziswa. Xa ipeyinti yokupeyinta enephalafini ifakwa kumphezulu wepeyinti, kuya kwenziwa umaleko omncinci weparafini kumphezulu, ukuze ezona molekyuli ziphambili zibe nexesha elaneleyo lokuhlala zingene kwifilimu yepeyinti ukuze isuswe, yiyo loo nto ukuphucula umphumo wokususa ipeyinti. I-parafini wax eqinileyo yodwa ihlala ibangela ukusasazeka okungafanelekanga, kwaye inani elincinci leparafini liyakuhlala ngaphezulu emva kokususwa kwepeyinti, okuya kuchaphazela ukuphinda kutshizwe. Ukuba kukho imfuneko, yongeza i-emulsifier ukunciphisa uxinzelelo lomhlaba ukuze i-wax yeparafini kunye neparafini engamanzi ikwazi ukusasazeka kakuhle kunye nokugcinwa kozinzo kuphuculwe.

7) Umtsalane

Ukongezwa kwama-surfactants, anjengee-amphoteric surfactants (umz., Imidazoline) okanye ethoxynonylphenol, inokunceda ukuphucula uzinzo lokugcina ipeyinti yokurhola kunye nokwenza lula ukucoca ipeyinti ngamanzi. Kwangelo xesha, ukusetyenziswa kweemolekyuli ezisebenza ngokusebenza kunye zombini lipophilic kunye nehydrophilic ezimbini ezichasene nepropathiant zinokuchaphazela ukusebenza kwe-solubilization; Ukusetyenziswa kweqela elisebenzayo le-colloidal, ukuze ukunyibilika kwezinto ezininzi kwisinyibilikisi kunyuke kakhulu. Izinto eziqhelekileyo ezisetyenziswayo zisebenza njengepropylene glycol, isodiyamethilini kunye ne-sodium xylenesulfonate.
