Imvelaphi
Iisilicone zizinto ezizodwa ezidibanisa iipropati zeekhompawundi ezingaphiliyo kunye ne-organic. Zibonisa uxinzelelo oluphantsi lomphezulu, i-viscosity-temperature coefficient ephantsi, ukucinezeleka okuphezulu, ukungena kwegesi ephezulu, kunye nokumelana okuhle kakhulu nobushushu obugqithisileyo, i-oxidation, i-weathering, amanzi kunye neekhemikhali. Azinabungozi, azinamsebenzi ngokwasemzimbeni, kwaye zineempawu ezintle kakhulu ze-dielectric.
Iimveliso zesilicone zisetyenziswa kakhulu ekutywineni, ekunamatheleni, ekuthambiseni, ekugqumeni, ekufakeni izinto ezibangela ukubola, ekususeni ivumba, ekususeni ivumba, ekuthinteleni ukungcoliswa kwamanzi, ekugqumeni ubushushu, nanjengezizalisi. Ukuveliswa kweesilicone kubandakanya inkqubo enzima enamanyathelo amaninzi:
•I-silica kunye ne-carbon ziguqulwa kubushushu obuphezulu zibe zii-siloxanes.
•Izinto eziphakathi ze-siloxane zesinyithi zi-chlorine, nto leyo evelisa ii-chlorosilanes.
•I-hydrolysis ye-chlorosilanes ivelisa iiyunithi ze-siloxane kunye ne-HCl, ezithi emva koko zihluzwe kwaye zicocwe.
•Ezi ziphakathi zenza ii-silicone oils, ii-resins, ii-elastomers, kunye nezinye ii-polymers ezineempawu ezahlukeneyo zokunyibilika kunye nokusebenza.
Kuyo yonke le nkqubo, abavelisi kufuneka basuse iintsalela ezingafunekiyo, amanzi, kunye namasuntswana ejeli ukuqinisekisa umgangatho wemveliso. Iinkqubo zokucoca ezizinzileyo, ezisebenzayo, nezilula ukuzigcina zibalulekile.
Umngeni wabathengi
Umenzi we-silicone wayefuna indlela esebenzayo ngakumbi yokwahlula izinto eziqinileyo nokulandelela amanzi ngexesha lokuveliswa. Inkqubo yabo isebenzisa i-sodium carbonate ukuphelisa i-hydrogen chloride, evelisa amanzi aseleyo kunye nezinto eziqinileyo. Ngaphandle kokususwa ngokufanelekileyo, ezi ntsalela zinokwenza iijeli, zinyuse ukuxinana kwemveliso kwaye zonakalise umgangatho.
Ngokwesiko, olu hlambululo lufunaamanyathelo amabini:
•Yahlula izinto eziqinileyo kwi-silicone intermediates.
•Sebenzisa izongezo ukususa amanzi.
Umthengi wayefuna i-isisombululo senyathelo elinyeiyakwazi ukususa izinto eziqinileyo, amanzi angaphantsi, kunye neejeli, ngaloo ndlela yenza kube lula inkqubo, inciphise inkunkuma ephuma kwimveliso, kwaye iphucule ukusebenza kakuhle kwemveliso.
Isisombululo
I-Great Wall Filtration yaphuhlisaI-SCPUbunzulu bothothoIsihluziIimodyuli, yenzelwe ukususa izinto eziqinileyo, amanzi aseleyo, kunye namasuntswana ejeli ngenyathelo elinye.
•Ubuchwepheshe: Iimodyuli ze-SCP zidibanisa imicu ye-cellulose emihle (evela kwimithi evuthulukayo kunye nemithi ye-coniferous) kunye nomhlaba we-diatomaceous okumgangatho ophezulu kunye neenkampani zokutshaja ze-cationic.
•Uluhlu Lokugcina: Uvavanyo lokuhluza oluqhelekileyo oluvela kwi0.1 ukuya kwi-40 µm.
•Ukusebenza OkuphuculweyoUvavanyo luchongeSCPA090D16V16Simodyuli eneUkugcinwa kwe-1.5 µmnjengeyona ifanelekileyo kolu setyenziso.
•Indlela yokusebenza: Umthamo oqinileyo wokufunxa amanzi kunye nesakhiwo esifanelekileyo semingxuma kuqinisekisa ukugcinwa okuthembekileyo kweejeli kunye namasuntswana anokuguquguquka.
•Uyilo lweNkqubo: Ifakwe kwintsimbi engagqwaliyo, iinkqubo zezindlu ezivaliweyo ezineendawo zokucoca ezivela0.36 m² ukuya kwi-11.7 m², enika ukuguquguquka kunye nokucoca okulula.
Iziphumo
•Ukwazile ukususa izinto eziqinileyo, amanzi amdaka, kunye neejeli ngendlela esebenzayo ngenyathelo elinye.
•Umsebenzi wemveliso olula, ususa isidingo seenkqubo ezimbini ezahlukeneyo.
•Ukunciphisa inkunkuma evela kwimveliso kunye nokusebenza kakuhle kwemveliso.
•Ifikelele ekusebenzeni okuzinzileyo nokuthembekileyo kokuhluza ngaphandle kokwehla okukhulu koxinzelelo.

FAQ
Q1: Kutheni ukuhluza kubalulekile kwimveliso yesilicone?
Ukucoca kuqinisekisa ukususwa kwezinto ezingafunekiyo eziqinileyo, amanzi angaphantsi, kunye namasuntswana ejeli anokuchaphazela kakubi umgangatho wemveliso, uzinzo, kunye nokuxinana. Ngaphandle kokucoca okusebenzayo, iisilicone zisenokungafikeleli kwimigangatho yokusebenza.
Umbuzo 2: Zeziphi iingxaki abavelisi abajongene nazo ekucoceni i-silicone?
Iindlela zemveli zifuna amanyathelo amaninzi—ukwahlula izinto eziqinileyo uze usebenzise izongezo ukususa amanzi. Le nkqubo ithatha ixesha elide, ibiza kakhulu, kwaye inokubangela inkunkuma eyongezelelweyo.
