Muva nje, kube nemibuzo eminingi evela kumakhasimende mayelana ne-putty powder, njengokuthambekela kwayo ekugayeni noma ukungakwazi kwayo ukuthola amandla. Kuyaziwa ukuthi ukwengezai-cellulose etherkuyadingeka ukwenza i-putty powder, futhi abasebenzisi abaningi abafaki i-latex powder ehlakazekayo. Abantu abaningi abafaki i-adhesive powder ukuze bonge izindleko, kodwa futhi lokhu kuyisihluthulelo sokuthi kungani i-putty evamile ivame ukuba nezinkinga zokugaywa kanye nekhwalithi yomkhiqizo!
Impuphu ye-latex ephinde ihlakazeke
I-putty ejwayelekile (njenge-putty engu-821) yenziwe kakhulu ngempuphu emhlophe, i-starch glue encane, kanye ne-CMC (hydroxymethyl cellulose), futhi kukhona naleyo eyenziwe nge-methyl cellulose kanye nempuphu ye-double fly. Lolu hlobo lwe-putty alunamatheli futhi alumelani namanzi.
Ngemva kokuncibilikisa i-cellulose namanzi, ingamunca amanzi futhi ikhule. Izinga lokumunca amanzi lemikhiqizo evela kubakhiqizi abahlukene lihlukile, futhi i-cellulose idlala indima yokugcina amanzi ku-putty. Ngemva kokoma, i-putty inamandla athile okwesikhashana, kodwa ngokuhamba kwesikhathi, izolahlekelwa kancane kancane yi-powder, ehlobene kakhulu nesakhiwo sama-molecule se-cellulose uqobo. Lolu hlobo lwe-putty lukhululekile, lumunca amanzi amaningi, luvame ukuba yi-powder, alunamandla, futhi aluguquguquki. Uma i-topcoat isetshenziswa kuyo, i-PVC ephansi ivame ukuba nama-blister; i-PVC ephezulu ivame ukuba nokuphelelwa amanzi emzimbeni, ukushwabana, kanye nokuqhekeka; Ngenxa yezinga layo eliphezulu lokumunca amanzi, ithinta ukwakheka kwefilimu kanye nomphumela wokwakhiwa kwe-topcoat.
Ukuze uthuthukise izinkinga ezingenhla nge-putty, ungalungisa ifomula ye-putty bese wengeza i-latex powder ephinde ihlakazeke ukuze uthuthukise amandla akamuva e-putty. Khetha i-hydroxypropyl methyl cellulose esezingeni eliphezulu.I-HPMCngokuqinisekiswa kwekhwalithi.I-Hydroxypropyl methyl celluloseinezinga lokugcina amanzi le-cellulose esezingeni eliphezulu, engamanzisa ngokugcwele izinto zokusetshenziswa ze-putty futhi ithuthukise ikhwalithi ye-putty.
Kuzoba yini umthelela kumpuphu we-putty uma inani lempuphu ye-latex ephinde ihlakazeke engezwe ngesikhathi senqubo yokukhiqiza i-putty linganele, noma uma kusetshenziswa impuphu ye-latex engeyona i-putty efanelekile?
Inani elanele lei-latex powder ephinde ihlakazekeOkungeziwe ku-putty kuwukubonakaliswa okuqondile kakhulu kwengqimba ye-putty ekhululekile, i-powdering surface, ukusetshenziswa kakhulu kopende lapho kufakwa i-topcoat, i-leveling embi, indawo elukhuni ngemva kokwakheka kwefilimu, kanye nobunzima bokwenza ifilimu yopende ebanzi. Izindonga ezinjalo zivame ukuxebuka, ukubhamuka, ukuxebuka, kanye nokuqhekeka kwefilimu yopende. Uma kukhethwa i-putty powder ephansi, izinga lokulimala emizimbeni yabantu okubangelwa amagesi ayingozi njenge-formaldehyde ekhiqizwa odongeni lisobala.
Ukuze kushintshwe isimo samanje, kuyadingeka ukususa yonke i-putty ephansi ngaphandle kokushiya noma iyiphi insalela, bese uthenga i-putty efanelekile kanye nopende we-latex! Ukuze kugwenywe ukulahlekelwa okungadingekile, amakhasimende kufanele azame ukukhetha imikhiqizo evela kumikhiqizo emikhulu enokuqinisekiswa kwekhwalithi ukuze kube lula ukukhetha i-putty.
Inkampani i-longou igxile ekukhiqizweni nasekuthengisweni kwemicu yokhuni, i-starch ether, i-hydroxypropyl methyl cellulose, i-latex powder ephinde ihlakazeke.
