Izinkinga ezijwayelekile zekhwalithi nezindlela zokuhlonza ze-latex powder ehlakazeka kabusha

Ngokuthuthuka okusheshayo kwemakethe yasekhaya yokonga amandla, izinkampani eziningi ze-R&D nezokukhiqiza sezingene ku-R&D kanye nokukhiqizwa kwemikhiqizo yempuphu ye-polymer ehlakazeka kabusha, futhi abasebenzisi banendawo yokuzikhethela, kodwa ngasikhathi sinye, ikhwalithi ye-polymer powder ehlakazeka kabusha ayilingani. , izinhlanzi ezixubile namadragoni. Ukuze kuncishiswe izindleko, abanye abakhiqizi abazinaki izindinganiso zekhwalithi, eziqinile njengezinhle, futhi abanye baze basebenzise izimpushana ze-resin ezivamile njengezimpushana ze-latex ezihlakazeka kabusha ukuze bazidayise ngamanani aphansi ngaphansi kokucasha kwempushana ye-latex ephinda ihlakazeka, engaphazamisi imakethe kuphela kodwa futhi. ukhohlisa umthengi. Kodwa emnothweni wemakethe lapho kusinda abanamandla, ikhwalithi ingumthombo wentuthuko esimeme, futhi akukho ngubo yokuzenzisa engayimboza. Ngamafuphi nje: ikhwalithi yizinga lentengo, umkhiqizo ilebula lekhwalithi, futhi imakethe iyindinganiso yokugcina yokuhlola.

◆Okokuqala, ake sihlaziye izinkinga zekhwalithi ezivamile zempushana ye-latex ehlakazeka kabusha, kanye nezindlela ezivamile kanye nokulimala kwabakhiqizi abangathembekile ukunciphisa izindleko:

◆ Indlela yokuhlukanisa noma ukuhlonza izinga le-latex powder elihlakazeka kabusha? Ukuze uthole indlela, qala ngokuhlaziya:

1. Ukuhlaziywa kwezinkomba zokukhiqiza

Izinkomba ziyisisekelo sokulinganisa ikhwalithi ye-latex powder ehlakazeka kabusha. Inkomba evamile iwukubonakaliswa kwezinombolo kokusebenza okuyisisekelo kwempushana ye-polymer ehlakazeka kabusha. Uma uhla lwenkomba lwe-polymer powder oluhlakazeka kabusha ludlula noma lwehluleka ukuhlangabezana nezinga, luzoba nomthelela oqondile ekusebenzeni kwalo. Izizathu eziyinhloko zezinkomba ezingavamile yizinkinga zokukhiqiza, njengobuchwepheshe bokukhiqiza obubuyela emuva, okokusebenza okuphelelwe yisikhathi noma okuguga, ukusetshenziswa kwezinto zokusetshenziswa ezishibhile nezisezingeni eliphansi, kanye nokuhlolwa kwefekthri okuxegayo kwemikhiqizo eqediwe. Ngaphezu kwalokho, abanye abakhiqizi bangosomathuba ukuze behlise izindleko, kungakhathalekile ukuthi ikhwalithi, futhi ayinalutho. Ngakho-ke, kuyadingeka ukukhetha umkhiqizi ovamile nothembekile.

2. Ukuhlaziywa kokusebenza okuyisisekelo

1. I-Redispersibility: i-latex powder ene-redispersibility enhle ingachithwa emanzini ukuze yenze i-emulsion ezinzile, futhi ukusatshalaliswa kosayizi wezinhlayiyana kufana ne-emulsion yasekuqaleni. Impushana yerabha inokuphinda ihlakazeke kahle, engakwazi ukuguqulwa ngokufanayo, futhi ingase iqukathe ama-polymer angaphinde ahlakazeke.

2. Izakhiwo zokwakha ifilimu yempuphu yerabha: Izakhiwo zokwakha ifilimu ziyisisekelo sezakhiwo zokuguqula udaka njengokunamathela. Izakhiwo ezingezinhle zokwakha ifilimu ngokuvamile zibangelwa ukwengezwa ngokweqile kwezakhi ze-inorganic noma izakhi ze-organic ezingafanele. Impushana ye-latex ehlakazeka kabusha yekhwalithi enhle inezindawo ezinhle zokwakha ifilimu ekamelweni lokushisa, futhi lezo ezinezimo ezingezinhle zokwakha ifilimu ezingeni lokushisa lasekamelweni ngokuvamile zinezinkinga zekhwalithi ngokokuqukethwe kwe-polymer noma umlotha.

3. Ukumelana namanzi kwefilimu: Impushana ye-latex ekwazi ukuphinda iphindwe kabusha inezinto ezinhle zokwenza ifilimu futhi inokumelana kahle namanzi. Izimpushana ze-latex ezinokungazweli kahle kwamanzi ngokuvamile ziqukethe ama-polymer amaningi ancibilika emanzini.

3. Ukuhlaziywa komphumela wohlelo lokusebenza

Kunqunywa ngokwezinga elisebenzayo:

1. Amandla ebhondi eyomile namandla ebhondi angavimbeli amanzi: isibopho asisihle, futhi kunezinkinga zekhwalithi mayelana ne-polymer noma umlotha.

2. Ukuguquguquka nokuphikisana nomthelela: Ukuguquguquka akukuhle, kunezinkinga zekhwalithi ku-polymer, futhi ukuguquguquka kunciphisa ngesikhathi sokusetshenziswa, okungase kube nama-plasticizers.

3. I-Hydrophobic kanye ne-non-hydrophobic: Indawo engaphezulu i-hydrophobic kakhulu, enganciphisa ukusebenza namandla okubopha kodaka.

4. Ukugeleza kanye ne-rheology: I-rheology ayilungile, futhi kunezinkinga zekhwalithi kuma-polymers noma izithasiselo.

5. Ukukhihliza amagwebu nokukhipha amagwebu: Ukuziphatha okungajwayelekile kwegwebu, izinkinga zekhwalithi ngama-polymer, umlotha noma izithasiselo.

◆ Izindlela ezimbalwa ezilula zokuhlonza impushana ye-latex ehlakazeka kabusha:

1. Indlela yokubukeka: mboza inani elincane le-latex powder elihlakazeka kabusha kancane kancane futhi ngokulinganayo phezu kwepuleti yengilazi ehlanzekile enenduku yengilazi, beka ipuleti lengilazi ephepheni elimhlophe, futhi uhlole ukubukeka kwezinhlayiya, izinto zangaphandle kanye nokuhlangana.

2. Indlela yokuhlakaza: Thatha inani elincane lempushana ye-latex ehlakazeka kabusha futhi uyifake emanzini izikhathi ezi-5, gudluza kuqala bese ulinda imizuzu emi-5 ukuze ubone. Empeleni, into encane engancibilikiyo eshona phansi, iba ngcono ikhwalithi yempushana ye-latex ehlakazeka kabusha.

3. Indlela yomlotha: Thatha inani elithile lempushana ye-latex ehlakazeka kabusha, uyikale, uyibeke esitsheni sensimbi, uyishise ifike kuma-degree angaba ngu-600, uyishise ekushiseni okuphezulu cishe imizuzu engama-30, uyipholise ifike ezingeni lokushisa elilingana negumbi, bese uyikala. futhi. Ikhwalithi enhle yesisindo esilula.

4. Indlela yokwenza ifilimu: Thatha inani elithile lempushana ye-latex ehlakazeka kabusha, uyifake emanzini izikhathi ezi-2, ugovuze ngokulinganayo, uyeke ume imizuzu emi-2, ugovuze futhi, qala uthele isixazululo engilazini eyisicaba, bese ingilazi Faka. ibe sethunzini elingena umoya. Ngemuva kokumisa, qaphela ukuthi ikhwalithi enokucaca okuphezulu yinhle.
