I-Litterx Powder evuselelayo ye-Latex (RDP) iyizinto ezibalulekile zokwakha futhi isetshenziswa kabanzi kuma-adhesives wokwakha, izinto zodonga, izinto zaphansi kanye nezinye izinkambu. Ukubuyiselwa kwemali okuhle kakhulu, ukunamathela nokuvumelana nezimo kukunika izinzuzo ezinkulu ngesikhathi sokwakha.
1. Ukulungiselela i-emulsion
Isinyathelo sokuqala ekwenzeni i-latex powder evuselelayo ukulungiswa kwe-emulsion. Lokhu kuvame ukwenziwa nge-emulsion polymerization. I-Emulsion polymerization uhlelo lwesigaba se -uquid esakhiwa ama-monomers asabalalisa ngokufana, ama-emulsifiers, amabanga kanye nezinye izinto eziluhlaza emanzini. Ngesikhathi senqubo ye-polymerization, ama-monomers polymerize ngaphansi kwesenzo sabaQandidayo ukwakha amaketanga we-polymer, ngaleyo ndlela akhiqize i-emulsion ezinzile.
Ama-monomers asetshenziswa kaningi we-emulsion polymerization afaka i-ethylene, acrylates, styrene, njll ngokuya ngezakhiwo ezidingekayo, ama-monomers ahlukile angakhethwa nge-Copolymerization. Isibonelo, i-ethylene-vinyl acetate copolymer (EVA) emulsion isetshenziswa kabanzi lapho kulungiswa i-latex evuselelayo ye-latex powder ngenxa yokumelana namanzi okuhle nokunamathelisa.
2. Ukufafaza
Ngemuva kokuthi i-emulsion isilungisiwe, idinga ukuguqulwa ibe yimpuphu ye-latex evundile ebusayo. Lesi sinyathelo sivame ukufinyelelwa ngobuchwepheshe bokuchomisa bokufafaza. I-Spray Corshing yindlela yokomisa eguqula ngokushesha izinto zoketshezi zibe yimpuphu.
Ngesikhathi senqubo yokusoma yokufafaza, i-emulsion ihlehlisiwe kumaconsi amahle ngokusebenzisa i-nozzle futhi uthinte ngomoya oshisayo wokushisa. Amanzi amaconsi avele avele avele avele avele avele, kanye nezinto eziqinile eziqinile zibe izinhlayiya ezincane ze-powder. Isihluthulelo sokusoma ngokufafaza ukulawula izinga lokushisa lokumisa nesikhathi sokuqinisekisa ubukhulu bezinhlayiyana zezinhlayiyana ze-latex powder kanye nokomisa owanele, ngenkathi ugwema ukonakala okunempilo okubangelwa amazinga okushisa aphezulu.
3. Ukwelashwa komhlaba
Ukuze uthuthukise ukusebenza nokuqina kwe-latex ebukekayo ye-latex, ingaphezulu kwalo kuvame ukwelashwa. Inhloso esemqoka yokwelashwa komhlaba ukwandisa uketshezi lwe-powder, thuthukisa ukuqina kwalo kokugcina futhi uthuthukise ukubuyiselwa kwalo emanzini.
Izindlela ezijwayelekile zokwelashwa komhlaba zifaka ukungezwa kwama-anti-casiking agents, ama-ejenti okuhlanganisa kanye nama-surfactants. Ama-anti-casiking agents angavimba i-powder ekuhambeni ngesikhathi sokugcina futhi alondoloze uketshezi lwayo oluhle; Ama-ejenti e-coating ajwayele ukusebenzisa amanye ama-polymers ancibilikayo amanzi ukuze afake i-latex powder ukuvikela ukungena komswakama; Ukungezwa kwama-surfactants kungathuthukisa ukubekezelela kwe-latex powder ukuze kusatshalaliswe ngokushesha nangokulinganayo ngemuva kokungeza amanzi.
4. Ukupakishwa nokugcinwa
Isinyathelo sokugcina kwinqubo yokukhiqiza ye-Latex Powder evuselelayo ukupakishwa nokugcinwa. Ukuze uqinisekise ikhwalithi nokusebenza komkhiqizo, kufanele kubhekwe ukuvikela umswakama, ukungcoliswa nothuli kusuka ekundizeni ngesikhathi senqubo yokupakisha. Imvamisa i-latex ye-latex ye-latex ephithizelayo ifakwe ezikhwameni zamaphepha amaningi noma ezikhwameni zepulasitiki ezinokumelana kahle komswakama, futhi kufakwa i-desiccant ngaphakathi kwesikhwama ukuvikela umswakama.
Lapho ugcina, i-latex ye-latex evuselelayo kufanele ibekwe endaweni eyomile, enomoya ovulekile, kude nokukhanya kwelanga okuqondile nendawo yokushisa ephezulu, ukuvikela ukuncishiswa kwempuphu noma ukonakaliswa kokusebenza.
Inqubo yokukhiqiza ye-latex ye-latex ye-latex ifaka izinyathelo eziningi ezifana nokulungiswa kwe-emulsion, ukomisa, ukwelashwa komhlaba, ukupakishwa kanye nokugcinwa. Ngokulawula ngokuqondile amapharamitha enqubo wesixhumanisi ngasinye, i-latex evuselelayo ye-latex enomsebenzi omuhle kakhulu futhi ikhwalithi ezinzile ingakhiqizwa ukuze ihlangabezane nezidingo ezihlukile zemboni yezinto zokwakha. Ngokuthuthuka okuqhubekayo kobuchwepheshe, inqubo yokulungiselela ye-latex powder evuselelayo izoba nobungane obuningi bemvelo futhi isebenze kahle esikhathini esizayo, futhi ukusebenza komkhiqizo nakho kuzothuthukiswa.
