Kwimeko-bume yokwenyani yemarike, iintlobo ngeentlobo zomgubo welatex zinokuchazwa njengokukhazimla. Ngenxa yoko, ukuba umsebenzisi akanalo iingcali zakhe zobuchwephesha okanye izixhobo zokuvavanya, unokukhohliswa kuphela ngabathengisi abaninzi abangathembekanga kwiimarike. Okwangoku, kukho iindlela ezibizwa ngokuba ziindlela zokufumanisa ezijikelezayo kwi-Intanethi, njengaku: ukujonga i-turbidity yesisombululo esinyibilikisiweyo kunye nemeko yokwenza ifilimu. Ezi ndlela kuphela cognition ukusuka kumphezulu, kwaye ayikwazi ukunika inkxaso yenzululwazi indlela ukuzimisela ukugqiba komsebenzisi ukuba imveliso ifanelekile kuye. Ngoko ke, kweli nqaku, siya kwazisa ngokucwangcisiweyo ezinye iikhonsepthi ezisisiseko zomgubo werabha simahla kwimiba yokwakheka kwezinto ezisisiseko ekrwada, iimpawu, kunye nenjongo yokusetyenziswa komgubo werabha, ukuze oogxa bazigwebe ngokwabo ukuba yintoni elungileyo nelungileyo. isiphene.
Okokuqala, ingcamango esisiseko yokuqonda indlela i-polymer eyinyani echithwa ngayo i powder yenziwa. (I-redispersible latex powder yipolymer powder eneempawu eziphinda ziphinde ziphinde ziguqulelwe kwi-synthetic resin emulsion ngokudibanisa ezinye izinto kunye ne-spray-yomileyo. Xa amanzi esetyenziswa njenge-dispersion medium, inokwenza i-emulsion kwaye ibe ne-polymer powder. izongezo, i-colloid ekhuselayo, i-agent anti-caking. 1. I-polymer resin ifumaneka kwinxalenye engundoqo ye-latex powder particles, kwaye nayo iyona nxalenye ephambili ye-latex powder edibeneyo, efana ne-polyvinyl acetate / i-vinyl resin, njl. Ukuqinisekisa ukuzinza komgangatho wemveliso, iifektri ezinkulu eziqhelekileyo zihlala zisebenzisa i-brand ye-polyvinyl acetate ukuvelisa i-polymer powder ephindwe kabini. Apha sinokuthatha umzekelo osebenzayo. Ngo-2015, i-brand eyaziwayo yasekhaya ye-powder rubber yasekhaya ithathe indawo ye-polyvinyl acetate emulsion eshibhile ukuvelisa i-polymer powder edispersible ngenxa yezizathu zokulawula. Ngenxa yoko, ukuguquguquka okukhulu komgangatho kuye kwabangelwa. kubangele umonakalo ongenakulungiseka. Nabarhwebi abanganyanisekanga apha baya kusebenzisa i-latex emhlophe kunye nezinto ezinjalo endaweni yothuli.
2. Izongezo (zangaphakathi) zisebenza kunye ne-resin ukuguqula i-resin, umzekelo, i-plasticizer enciphisa ukushisa kwefilimu yokwenza ifilimu ye-resin (ngokuqhelekileyo i-vinyl acetate / i-ethylene copolymer resins ayidingi ukongeza i-plasticizers), kungekhona yonke i-latex Powder inezongezo. I-latex powder ehlaziywayo yabaninzi abancinci abavelisi abancinci kuphela ifilimu eyenza isalathisi seqondo lokushisa kwaye ayikwazi ukubizwa ngokuba yi-glass transition yeqondo lokushisa, elikwayiparameter ebalulekileyo yomgangatho we-rubber powder ngokwayo.
3. I-colloid ekhuselayo Umaleko wezinto ze-hydrophilic ezisongelwe kumphezulu wamasuntswana omgubo we-latex adispersible, kunye nomzimba okhuselayo weyona powders ye-latex ephinda ihlakazwe yi-polyvinyl alcohol. I-alcohol ye-polyvinyl apha kukuthatha inxaxheba kwinkqubo yokutshiza kunye, kunokuba nje ixutywe. Nantsi enye ingxaki eqhelekileyo kwiimarike. Iindibano zocweyo ezininzi ezincinci ezithi zivelisa umgubo werabha zenza nje inkqubo yokuxuba ngokomzimba. Inkqubo, le mveliso ayinakubizwa ngokungqongqo ukuba yi-disperible polymer powder.
4. Izongezo (zangaphandle) Izinto ezidityanisiweyo zokwandisa ngakumbi ukusebenza komgubo welatex odispersible, njengokongeza ii-superplasticizers kumgubo othile welatex omanzi. Njengezongezo zangaphakathi, ayilulo lonke uhlobo lwepolymer powder ephinda isetyenziswe. I-latex powders zonke ziqulethe esi songezo.
5. I-agent ye-Anti-caking I-Fine mineral filler, isetyenziselwa ukukhusela i-latex powder kwi-agglomeration ngexesha lokugcinwa kunye nokuthutha kunye nokuququzelela ukuhamba kwe-latex powder (ekulahlwa kwiingxowa zephepha okanye iitanki). Esi sigcwalisi sikwayinxalenye eya kuchaphazela kakhulu eyona ndleko yemveliso kunye nokusebenza kwepolymer powder. Iipowders ezininzi zerabha ezinexabiso eliphantsi kwimarike zonyusa umlinganiselo wokuzalisa ukunciphisa iindleko. Ukubeka ngokulula, sisalathisi somxholo womlotha odla ngokubhekiswa kuwo. Iifayili ezahlukeneyo ezongeziweyo ngabavelisi abahlukeneyo ziya kuchaphazela impembelelo yokuxuba i-rubber powder kunye nesamente. Ngenxa yokuba i-adhesive inorganic adhesives ifumaneka ngomgaqo wokufakela oomatshini
