Ngokuphathelele ingxaki yokuba i-putty powder ilula ukuba ibe ngumgubo, okanye amandla awanele.Njengoko sonke siyazi, i-cellulose ether kufuneka yongezwe ukwenza i-putty powder, i-HPMC isetyenziselwa i-putty eludongeni, kwaye abasebenzisi abaninzi abafaki i-latex powder.Abantu abaninzi abafaki umgubo wepolymer ukuze kugcinwe iindleko, kodwa oku kusisitshixo sokuba kutheni i-putty eqhelekileyo ilula ibe ngumgubo kwaye ixhomekeke kwiingxaki zomgangatho wemveliso!
I-putty eqhelekileyo (efana ne-821 putty) yenziwe ngokukodwa ngomgubo omhlophe, isitashi esincinci seglue kunye ne-CMC (i-hydroxymethyl cellulose), kwaye ezinye zenziwe nge-methyl cellulose kunye ne-Shuangfei powder.Le putty ayinakuncamathela kwaye ayinyangeki emanzini.
I-cellulose inokufunxa amanzi kwaye idumbe emva kokuba inyibilikiswe emanzini.Iimveliso ezivela kubavelisi abahlukeneyo zinemilinganiselo eyahlukeneyo yokufunxa amanzi.I-Cellulose idlala indima yokugcina amanzi kwi-putty.I-putty eyomileyo inamandla athile okwethutyana, kwaye iya kuthotywa kancinci emva kwexesha elide.Oku kuhambelana ngokusondeleyo nesakhiwo se-molecular of cellulose ngokwayo.Iputty enjalo iyaxengalala, ifunxa kakhulu amanzi, kulula ukuyicoca, ayinamandla, yaye ayinakunwebeka.Ukuba i-topcoat ifakwe phezulu, i-PVC ephantsi kulula ukugqabhuka kunye ne-foam;i-PVC ephezulu kulula ukuyicutha kunye nokuqhekeka;ngenxa yokunyuswa kwamanzi aphezulu, kuya kuchaphazela ukubunjwa kwefilimu kunye nesiphumo sokwakhiwa kwe-topcoat.
Ukuba ufuna ukuphucula iingxaki ezi ngasentla ze-putty, unokulungelelanisa i-putty formula, yongeza enye i-latex powder edibeneyo ngokufanelekileyo ukuphucula amandla kamva we-putty, kwaye ukhethe i-high quality hydroxypropyl methylcellulose HPMC kunye nomgangatho oqinisekisiweyo.
Kwinkqubo yokuvelisa i-putty, ukuba inani le-latex powder eyongeziweyo eyongeziweyo akwanele, okanye ukuba i-latex engaphantsi kwe-powder ye-putty isetyenzisiweyo, yintoni impembelelo eya kuba nayo kwi-putty powder?
Isixa esingonelanga seputty redispersible latex powder, eyona nto ibonakalisa ngokuthe ngqo kukuba umaleko weputty ukhululekile, umphezulu uyacolwa, ubungakanani bepeyinti esetyenziselwa ukugquma phezulu bukhulu, ipropathi yokulinganisa imbi, umphezulu urhabaxa emva kokwenziwa kwefilimu, kwaye kunzima ukwenza ifilimu yepeyinti eshinyeneyo.Iindonga ezinjalo zivame ukuxobulwa, ukugqabhuka, ukukhupha, kunye nokuqhekeka kwefilimu yepeyinti.Ukuba ukhetha i-putty ephantsi, kuyacaca ukuba iigesi ezinobungozi ezifana ne-formaldehyde eveliswa eludongeni ziya kubangela ingozi emzimbeni kwabanye.
