Ngokuphathelene nenkinga yokuthi i-putty powder kulula ukuyimpusha, noma amandla awanele.Njengoba sonke sazi, i-cellulose ether idinga ukwengezwa ukwenza i-putty powder, i-HPMC isetshenziselwa i-wall putty, futhi abasebenzisi abaningi abafaki i-latex powder ephindwe kabusha.Abantu abaningi abafaki i-polymer powder ukuze bonge izindleko, kodwa lokhu futhi kuyisihluthulelo sokuthi kungani i-putty evamile ilula ibe yimpushana futhi ijwayele izinkinga zekhwalithi yomkhiqizo!
I-Ordinary putty (njenge-821 putty) yenziwe ngokuyinhloko ngempushana emhlophe, iglue isitashi esincane ne-CMC (hydroxymethyl cellulose), kanti ezinye zenziwe nge-methyl cellulose ne-Shuangfei powder.Le putty ayinakho ukunamathela futhi ayimelani namanzi.
I-cellulose ingamunca amanzi futhi ikhukhumale ngemva kokuncibilika emanzini.Imikhiqizo evela kubakhiqizi abahlukene inamazinga ahlukene okumunca amanzi.I-Cellulose idlala indima ekugcineni amanzi ku-putty.I-putty eyomile inamandla athile okwesikhashana, futhi izophuma kancane kancane ngemva kwesikhathi eside.Lokhu kuhlobene eduze nesakhiwo se-cellulose ngokwayo.I-putty enjalo iyaxega, imunca kakhulu amanzi, kulula ukuyihlikihla, ayinawo amandla, futhi ayinakho ukunwebeka.Uma i-topcoat isetshenziswa phezulu, i-PVC ephansi kulula ukuqhuma kanye negwebu;i-PVC ephezulu kulula ukuncipha nokuqhekeka;ngenxa yokumuncwa kwamanzi amaningi, kuzothinta ukwakheka kwefilimu nomphumela wokwakhiwa kwe-topcoat.
Uma ufuna ukuthuthukisa izinkinga ezingenhla ze-putty, ungalungisa ifomula ye-putty, wengeze enye i-latex powder ehlakazeka kabusha ngokufanele ukuze uthuthukise amandla kamuva we-putty, futhi ukhethe ikhwalithi ephezulu ye-hydroxypropyl methylcellulose HPMC ngekhwalithi eqinisekisiwe.
Enqubweni yokukhiqiza i-putty, uma inani le-latex powder eliphindwe kabusha elingeziwe linganele, noma uma i-latex powder ephansi ye-putty isetshenziswa, kuzoba namuphi umthelela ku-putty powder?
Inani elinganele le-putty redispersible latex powder, ukubonakaliswa okuqondile kakhulu ukuthi ungqimba lwe-putty luxega, indawo engaphezulu iyacolwa, inani likapende osetshenziselwa ukugcoba phezulu likhulu, indawo yokulinganisa imbi, ingaphezulu lilukhuni ngemva kokwakhiwa kwefilimu, futhi kunzima ukwakha ifilimu kapende eliminyene.Izindonga ezinjalo zivame ukuxebuka, amabhamuza, ukuxebuka, nokuqhekeka kwefilimu kapende.Uma ukhetha i-putty powder ephansi, kusobala ukuthi amagesi ayingozi afana ne-formaldehyde akhiqizwa odongeni azobangela ukulimala ngokomzimba kwabanye.
