Ama-microsphere engilazi angenalutho okugcwalisa upende
Ama-microsphere engilazi angenalutho ama-microspheres engilazi ane-low density, isisindo esilula namandla aphezulu. Ngenxa yezici ezingenalutho, uma kuqhathaniswa nobuhlalu bengilazi obujwayelekile, inezici zesisindo esilula, ukuminyana okuphansi nokusebenza okuhle kokushisa okushisayo. Indlela yengezwe ngokuqondile ohlelweni lokugqoka, ukuze ifilimu yokugqoka eyenziwe ngokuphulukiswa kokugqoka inezindawo zokushisa ezishisayo. Ngaphezu kokumuncwa kwawo okuphansi kawoyela kanye nokuminyana okuphansi, ukwengeza u-5% (wt) kungakhuphula umkhiqizo oqediwe ngo-25% kuya ku-35%, ngaleyo ndlela kungakhuli noma kunciphise ngisho nezindleko zevolumu yeyunithi yokumboza.
Ama-microsphere engilazi angenalutho ayizindilinga eziyizigodi ezivaliwe, ezifakwa embotsheni ukuze zakhe izimbotshana eziningi ezizimele zokuvala ukushisa okushisayo, ngaleyo ndlela kuthuthukiswe kakhulu ukugqunywa kwefilimu enamathelayo ekushiseni nomsindo futhi idlala indima enhle ekwehliseni ukushisa nasekunciphiseni umsindo. Yenza okokumboza kungangeni manzi kakhulu, kunqande ukubola kanye nezindawo zokunqanda ukugqwala. Indawo engasebenzi ngamakhemikhali ye-microbeads imelana nokugqwala kwamakhemikhali. Lapho kwakhiwa ifilimu, izinhlayiya zeingilazi microbeads zihlelwe eduze ukuze zenze i-porosity ephansi, ukuze indawo yokumboza yakha ifilimu evikelayo enomphumela wokuvimbela umswakama kanye nama-ion abolayo, adlala indima enhle ekuvikelweni. umphumela.
Isakhiwo esiyindilinga sobuhlalu bengilazi obungenalutho siyenza ibe nomthelela omuhle wokuhlakazeka kumandla omthelela kanye nengcindezi. Ukuyengeza embotsheni kungathuthukisa ukumelana komthelela wefilimu yokugqoka futhi kunganciphisa nokwanda okushisayo nokufinyela kwengubo. yokuqhekeka kwe-stress.
Ukukhanya okungcono nomphumela wokufiphaza. I-powder emhlophe inomphumela omhlophe ongcono kune-pigments evamile, inciphisa ngokuphumelelayo inani lamanye ama-fillers abizayo kanye nama-pigments (uma kuqhathaniswa ne-titanium dioxide, izindleko zevolumu yama-microbeads cishe yi-1/5 kuphela) Ukuthuthukisa ngokuphumelelayo ukunamathela kokugxila kokumboza. Izici zokumunca uwoyela eziphansi zama-microbeads engilazi zivumela i-resin eyengeziwe ukuthi ibambe iqhaza ekwakhiweni kwefilimu, ngaleyo ndlela ikhulise ukunamathela kokunamathela izikhathi ezi-3 kuye kwezi-4.
Ukwengeza u-5% wama-microbeads kungenza ukuminyana kwe-coating kusuka ku-1.30 kuye ngaphansi kuka-1.0, ngaleyo ndlela kwehlise kakhulu isisindo sokumboza futhi kugweme ukwenzeka kokuxebuka kodonga.
Ama-Microbeads anomphumela omuhle wokubonisa emisebeni ye-ultraviolet, evimbela ukunamathela ekuphuzini nasekugugeni.
Iphuzu eliphakeme lokuncibilika kwama-microbeads lithuthukisa kakhulu ukumelana nokushisa kwe-coating futhi lidlala indima enhle kakhulu ekuvimbeleni umlilo. Izinhlayiya eziyindilinga zama-microbeads zidlala indima yama-bearings, futhi amandla okungqubuzana mancane, angathuthukisa ukusebenza kokugeleza kwe-coating futhi enze ukwakhiwa kube lula.
Izincomo zokusetshenziswa: Inani elijwayelekile elihlanganisayo lingu-10% wesisindo esiphelele. Ama-microbeads alashwa ngaphezulu futhi anokuqina okuphansi, okwenza ukunamathela kuthambekele ekukhuleni kwe-viscosity futhi kuntante ngesikhathi sokugcina. Sincoma ukwandisa i-viscosity yokuqala ye-coating (ngokwandisa inani elingeziwe le-thickener lilawula i-viscosity ngaphezu kwe-140KU), kulokhu, into entantayo ngeke yenzeke ngoba i-viscosity iphansi kakhulu, futhi izinhlayiya zento ngayinye Uhlelo luyancipha emsebenzini ngenxa ye-viscosity ephezulu, enenzuzo yokulawula i-viscosity. ukuzinza. Sincoma ngokuqinile le ndlela yokwengeza elandelayo: ngoba ama-microbead anezindonga ezincane zezinhlayiya kanye nokumelana okuphansi kwe-shear, ukuze usebenzise ngokugcwele izici ezingenalutho zama-microbeads, kunconywa ukuthatha indlela yokugcina yokwengeza, okungukuthi, ukubeka ama-microbeads endaweni. ukuphela kwe Ukwengezwa kuhlakazwa ngokushukumisa imishini enejubane eliphansi namandla okugunda okuphansi ngangokunokwenzeka. Ngenxa yokuthi ukwakheka okuyindilinga kwama-microbeads kunoketshezi oluhle futhi ukungqubuzana phakathi kwawo akukukhulu, kulula ukukuhlakaza. Ingamanziswa ngokuphelele ngesikhathi esifushane, vele yelule isikhathi sokunyakazisa ukuze kuzuzwe ukuhlakazeka okufanayo.
I-Microbeads ayisebenzi ngamakhemikhali futhi ayinabo ubuthi. Kodwa-ke, ngenxa yesisindo sayo esilula kakhulu, ukunakekelwa okukhethekile kuyadingeka lapho wengeza. Sincoma indlela yokwengeza yesinyathelo ngesinyathelo, okungukuthi, inani lokungezwa ngakunye yi-1/2 yama-microbead asele, futhi yengezwe kancane kancane, engavimbela kangcono ama-microbeads ukuthi angantanti emoyeni futhi enze ukuhlakazeka kuphelele.
