Kutshanje, kuye kwakho imibuzo rhoqo kubathengi malunga ne-putty powder, njengokutyekela kwayo ukucofa okanye ukungakwazi kwayo ukufumana amandla.Kuyaziwa ukuba ukongezai-cellulose etherkuyimfuneko ukwenza iputty powder, kwaye abasebenzisi abaninzi abafaki i-latex powder.Abantu abaninzi abafaki umgubo wokuncamathelisa ukonga iindleko, kodwa oku kukwasisitshixo sokuba kutheni i-putty eqhelekileyo ityekele kwi-pulverization kunye nemiba yomgangatho wemveliso!
I-latex powder enokuchithwa kwakhona
Iputty eqhelekileyo (efana ne 821 putty) yenziwe ikakhulu ngomgubo omhlophe, isitatshi esincinci seglu, kunye neCMC (hydroxymethyl cellulose), kwaye zikho nezo zenziwe ngemethyl cellulose kunye nomgubo ophindwe kabini.Olu hlobo lwe-putty alunamatheli kwaye alukwazi ukumelana namanzi.
Emva kokunyibilikisa i-cellulose kunye namanzi, inokufunxa amanzi kwaye yandise.Izinga lokufunxa amanzi kwiimveliso ezivela kubavelisi abahlukeneyo lihlukile, kwaye i-cellulose idlala indima yokugcina amanzi kwi-putty.Emva kokumisa, i-putty inamandla okwexeshana kuphela, kodwa ngokuhamba kwexesha, iya kulahlekelwa ngumgubo ngokuthe ngcembe, ehambelana ngokusondeleyo nesakhiwo se-molecular of cellulose ngokwayo.Olu hlobo lwe-putty lukhululekile, lufunxa kakhulu amanzi, luthanda ukuba ngumgubo, alunamandla, kwaye lunwebeka.Ukuba i-topcoat ifakwe kuyo, i-PVC ephantsi ithanda ukudumba;I-PVC ephakamileyo ixhomekeke ekuphelelweni kwamanzi emzimbeni, i-shrinkage, kunye nokuqhekeka;Ngenxa yezinga eliphezulu lokufunxa kwamanzi, lichaphazela ukubunjwa kwefilimu kunye nomphumo wokwakha we-topcoat.
Ukuphucula le miba ingentla nge-putty, unokuhlengahlengisa i-putty formula kwaye wongeze umgubo we-latex onokuphinda uhlawulwe ukuphucula amandla amva eputty.Khetha i-hydroxypropyl methyl cellulose ekumgangatho ophezuluHPMCngoqinisekiso lomgangatho.I-Hydroxypropyl methyl celluloseinezinga lokugcinwa kwamanzi kwi-cellulose ephezulu, enokuthi ifake ngokupheleleyo i-putty impahla eluhlaza kunye nokuphucula umgangatho we-putty.
Iya kuba yintoni impembelelo kwi-putty powder ukuba inani le-latex powder elidispersible elongezelelweyo ngexesha lenkqubo yokuvelisa i-putty ayanelanga, okanye ukuba i-putty engaphantsi kwe-latex powder isetyenziswe?
Isixa esingonelanga sei-latex powder enokuchithwa kwakhonaeyongeziweyo kwi-putty yeyona nto ibonakalisa ngokuthe ngqo i-putty layer, umgubo womphezulu, ukusetyenziswa kwepeyinti ephezulu xa usebenzisa i-topcoat, ukulinganisa okungahambi kakuhle, indawo erhabaxa emva kokwenziwa kwefilimu, kunye nobunzima bokwenza ifilimu yepeyinti eshinyeneyo.Iindonga ezinjalo zivame ukuxobulwa, ukugqabhuka, ukukhupha, kunye nokuqhekeka kwefilimu yepeyinti.Ukuba i-powder putty ephantsi ikhethiwe, iqondo lobungozi kwimizimba yabantu ebangelwa yigesi eyingozi efana ne-formaldehyde eyenziwe eludongeni ibonakala.
Ukutshintsha imeko yangoku, kuyimfuneko ukususa yonke i-putty engaphantsi ngaphandle kokushiya nayiphi na intsalela, kwaye emva koko uthenge i-putty efanelekileyo kunye nepeyinti ye-latex!Ukuze ugweme ilahleko engeyomfuneko, abathengi kufuneka bazame ukukhetha iimveliso kwiimpawu ezinkulu kunye nokuqinisekiswa komgangatho ukwenzela ukuba kube lula ukukhetha i-putty.
Inkampani ye-longou igxile kwimveliso kunye nentengiso yeentsinga zomthi, i-starch ether, i-hydroxypropyl methyl cellulose, i-latex powder
