Nekuda kwemaitiro avo emakemikari akasiyana, cellulose ethers ndiwo akakosha ekugadzira pendi yelatex.Iwo anoshandiswa mu latex pendi seakobvu, rheology modifiers, inodzivirira colloids uye mvura inochengetedza vamiririri.Cellulose ethers inoita basa rakakosha mukugadzira nekushandiswa kwependi yelatex, uye kushandiswa kwavo kwave kunozivikanwa muindasitiri yekupfeka.
Thickeners uye Rheology Modifiers:
Rimwe remabasa ekutanga e-cellulose ethers rakaita semakobvu uye rheology modhifita.Rheology ndiko kudzidza kwedeformation uye kuyerera kwenyaya, uye inoita basa rakakosha mukushandiswa kwemajasi.Rheology modifiers inowedzerwa kune pendi maumbirwo ekudzora kuyerera maitiro ependi uye kuve nechokwadi chakaenderana manyorerwo uye kufukidzwa.Nekuita semakobvu uye rheology modhifita, cellulose ethers inogona kukora latex pendi uye kuita kuti zvive nyore kuisa.
Cellulose ethers mapolymer anonyungudika mumvura akafanana nekemikari yakafanana neselulosi, iyo inongoitika polima inowanikwa muzvirimwa.Iyo yakasarudzika kemikari zvimiro zve cellulose ethers inovabvumira kukobvura latex pendi pasina zvakanyanya kukanganisa viscosity yayo, kuve nechokwadi chekuti pendi ine yakatsetseka, kunyange magadzirirwo.
Nekuda kwekukora kwavo zvimiro, cellulose ethers zvakare inosimudzira inonamira zvimiro zvejasi.Nekuwedzera kuwanda kwefirimu yepende, inobatsira kuvandudza chisungo pakati pepende nepamusoro, kuve nechokwadi kuti pende inogara kwenguva refu.
Dziviriro colloid:
Cellulose ethers macolloid anodzivirira anoshanda anobatsira kudzikamisa macolloidal particles mulatex pendi.Colloids zvidimbu zvidiki zvakaparadzirwa mukati, mune iyi kesi, pendi.Kugadzikana kwezvikamu izvi zvakakosha pakuchengetedza kutendeseka kwese kwekugadzirisa kwekugadzira.
Kuwedzera cellulose ethers kune yekuputira magadzirirwo anovimbisa kuti iyo colloidal particles inoramba yakapararira yakapararira mumucheka, kudzivirira kuumbwa kwezviputi.Pamusoro pezvo, iyo inodzivirira colloid zvimiro zve cellulose ethers inodzivirira latex pendi kuti isanyanya kukora kana kuoma nekufamba kwenguva.Izvi zvinozoita kuti pendi iri nyore kuisa uye inoramba yakatsiga uye isingachinji panguva yese yekushandisa.
Kuchengeta mvura:
Chimwe chinhu chakakosha che cellulose ethers kugona kwavo kubata mvura.Mukugadzirwa kwependi, mvura inowanzowedzerwa se diluent kuti igadzire yakatsetseka, yakagadzikana uye inonatsiridza maitiro ekushandiswa kwepende.Zvisinei, mvura inogonawo kuita kuti pendi iome nokukurumidza, zvichiita kuti chisungo chiri pakati pepende nepamusoro chishaye simba.
Nekuchengeta hunyoro, cellulose ethers inova nechokwadi chekuti iyo coating inoramba ine hydrated mukati mekuita kwekunyorera, ichidzivirira kubva pakuoma nekukasira.Izvi zvinobvumira pende kuti iome zvakaenzana uye igadzire chisungo chakasimba, chinogara kwenguva refu nechepamusoro.
mukupedzisa:
Cellulose ethers chinhu chakakosha chelatex pendi nekuda kweiyo yakasarudzika kemikari.Iwo anoshandiswa mukuputira maumbirwo seakasimba, rheology modifiers, inodzivirira colloids uye mvura inochengetedza vamiririri.Nekupa mabasa mazhinji aya, cellulose ethers inovimbisa kuti latex pendi inoramba yakagadzikana, inowirirana uye iri nyore kuisa.Kushandisa kwavo kwakashandura indasitiri yekupfeka, uye zvakanakira zvavo zvinozivikanwa zvakanyanya nevagadziri uye vashandisi.
