Muva nje, kube nemibuzo kaningi evela kumakhasimende mayelana ne-putty powder, njengokuthambekela kwayo ukucofa noma ukungakwazi kwayo ukuzuza amandla.Kuyaziwa ukuthi ukwengezai-cellulose etherkuyadingeka ukwenza i-putty powder, futhi abasebenzisi abaningi abayingezi impushana ye-latex ehlakazekayo.Abantu abaningi abafaki impushana enamathelayo ukuze bonge izindleko, kodwa lokhu futhi kuyisihluthulelo sokuthi kungani i-putty evamile ijwayele ukugaywa kanye nezinkinga zekhwalithi yomkhiqizo!
Impushana ye-latex ehlakazeka kabusha
I-Ordinary putty (efana ne-821 putty) yenziwe kakhulu ngempushana emhlophe, ingcina yesitashi esincane, ne-CMC (hydroxymethyl cellulose), kanti kukhona naleyo eyenziwe nge-methyl cellulose kanye nempushana ephindwe kabili.Lolu hlobo lwe-putty alunamatheli futhi alukwazi ukumelana namanzi.
Ngemva kokuhlakaza i-cellulose namanzi, ingamunca amanzi futhi yande.Izinga lokumuncwa kwamanzi lemikhiqizo evela kubakhiqizi abahlukene lihlukile, futhi i-cellulose idlala indima yokugcina amanzi ku-putty.Ngemuva kokumisa, i-putty inamandla okwesikhashana kuphela, kodwa ngokuhamba kwesikhathi, izolahlekelwa kancane kancane i-powder, ehlobene eduze nesakhiwo se-cellulose ngokwayo.Lolu hlobo lwe-putty luyaxega, lumunca amanzi amaningi, luthambekele ekubeni yimpushana, alunawo amandla, nokunwebeka.Uma i-topcoat ifakwe kuyo, i-PVC ephansi ijwayele ukuqhuma;I-PVC ephezulu ijwayele ukuphelelwa amanzi emzimbeni, ukuncipha, nokuqhekeka;Ngenxa yezinga eliphezulu lokumuncwa kwamanzi, lithinta ukwakheka kwefilimu nomphumela wokwakhiwa kwejazi eliphezulu.
Ukuze uthuthukise lezi zinkinga ezingenhla nge-putty, ungalungisa ifomula ye-putty bese wengeza impushana ye-latex ehlakazeka kabusha ukuze uthuthukise amandla akamuva e-putty.Khetha i-hydroxypropyl methyl cellulose yekhwalithi ephezuluI-HPMCngokuqinisekiswa kwekhwalithi.I-Hydroxypropyl methyl celluloseinezinga lokugcinwa kwamanzi le-cellulose yekhwalithi ephezulu, engakwazi ukukhipha ngokugcwele i-putty impahla eluhlaza futhi ithuthukise ikhwalithi ye-putty.
Uzoba yini umthelela ku-putty powder uma inani le-latex powder eliphindwe kabusha elingeziwe ngesikhathi senqubo yokukhiqiza i-putty linganele, noma uma i-putty ephansi ye-latex powder isetshenziswa?
Inani elinganele lei-latex powder ehlakazeka kabushaokwengezwe ku-putty ukubonakaliswa okuqondile kakhulu kwe-putty layer, i-powdering ebusweni, ukusetshenziswa kopende okuphezulu lapho usebenzisa i-topcoat, izinga eliphansi, indawo embi kakhulu ngemva kokwakhiwa kwefilimu, nobunzima bokwenza ifilimu kapende eliminyene.Izindonga ezinjalo zivame ukuxebuka, amabhamuza, ukuxebuka, nokuqhekeka kwefilimu kapende.Uma kukhethwa i-putty powder ephansi, izinga lokulimala emizimbeni yabantu elibangelwa amagesi ayingozi njenge-formaldehyde ekhiqizwa odongeni liyabonakala.
Ukuze ushintshe isimo samanje, kuyadingeka ukususa yonke i-putty engaphansi ngaphandle kokushiya noma iyiphi insalela, bese uthengela i-putty efanelekayo nopende we-latex!Ukuze ugweme ukulahlekelwa okungadingekile, amakhasimende kufanele azame ukukhetha imikhiqizo evela kumikhiqizo emikhulu enesiqinisekiso sekhwalithi ukuze kube lula ukukhetha i-putty.
Inkampani ye-longou igxile ekukhiqizeni nasekudayiseni imicu yokhuni, isitashi ether, i-hydroxypropyl methyl cellulose, impushana ye-latex edispersible
