I-seam-polishing esezantsi yengubo yolwandle echasene nokungcola
Ingcaciso yeMveliso
Ipeyinti yokuzikhusela ekungcoliseni yimveliso ekhethekileyo yokugquma. Ngokuyintloko ifumana impendulo yekhemikhali kumphezulu wokugquma. Njengoko inqanawa ihamba emanzini, ukugquma kuya kucola kancinci nangokulinganayo kwaye kunyibilike ngokwako. Olu phawu lwenza ukuba umphezulu wenqanawa uhlale ucocekile kwaye uthintele ngokufanelekileyo izinto eziphilayo zaselwandle ezifana ne-shellfish kunye ne-algae ekunamatheleni kwi-shell.
Umgaqo wokuzicoca ngepeyinti ethintela ukungcoliswa usekelwe kulwakhiwo lwayo lweekhemikhali olukhethekileyo. Iqulethe iipolymers ezikwaziyo ukucoliswa ngamanzi kunye nezongezo ezinobungozi ngokwebhayoloji. Kwindawo emanzi olwandle, iipolymers ziya kucoliswa ngamanzi kancinci kancinci, zihlaziye rhoqo umphezulu wepeyinti ethintela ukungcoliswa ngamanzi, ngelixa izongezo ezinobungozi ngokwebhayoloji zinokuthintela ukunamathela kwezinto eziphilayo zaselwandle kumphezulu osandul’ ukubonakala.
- Xa kuthelekiswa neepeyinti zemveli zokuthintela ukungcoliswa, iipeyinti zokuthintela ukungcoliswa ezizipolishayo zinezibonelelo ezibalulekileyo. Emva kokuba iipeyinti zemveli zokuthintela ukungcoliswa zisetyenzisiwe ixesha elithile, isiphumo sokuthintela ukungcoliswa siya kuncipha kancinci kancinci, kwaye kufuneka ukuphinda kusetyenziswe rhoqo. Oku akudli nje ixesha elininzi kunye neendleko kodwa kunokuba nefuthe elithile kwindalo esingqongileyo. Ngokwahlukileyo koko, iipeyinti zokuthintela ukungcoliswa ezizipolishayo zinokuqhubeka nokusebenzisa isiphumo sazo sokuthintela ukungcoliswa ixesha elide, kunciphisa ukugcinwa kunye nokuphinda kusetyenziswe inqanawa.
- Kwimisebenzi ebonakalayo, iipeyinti ezizipolishayo ezithintela ukungcola zisetyenziswa kakhulu kwiintlobo ngeentlobo zeenqanawa, kuquka iinqanawa zorhwebo, iinqanawa zemfazwe, kunye neenqanawa. Kwiinqanawa zorhwebo, ukugcina inqanawa icocekile kunokunciphisa ukumelana nokuhamba ngenqanawa nokuphucula ukusebenza kakuhle kwepetroli, ngaloo ndlela konga iindleko zokusebenza. Kwiinqanawa zorhwebo, ukusebenza kakuhle kokuthintela ukungcola kunceda ukuqinisekisa isantya sokuhamba ngenqanawa kunye nokuhamba kwayo kwaye kuphucula ukusebenza kakuhle kokulwa. Kwiinqanawa zorhwebo, inokugcina inqanawa ibukeka ikwimeko entle ngamaxesha onke kwaye iphucule ubuhle bayo.
- Ngenxa yeemfuno ezingqongqo zokukhusela okusingqongileyo, iipeyinti ezizicocayo ezithintela ukungcola nazo zihlala ziphuhliswa kwaye zintsha. Abasebenzi be-R & D bazimisele ukunciphisa ukusetyenziswa kwezongezo ezinetyhefu kwibhayoloji ngelixa bephucula ukusebenza kwepeyinti ethintela ukungcola ukuze kufezekiswe isiphumo esinobuhlobo nokusingqongileyo nesisebenzayo sokuthintela ukungcola. Ezinye iipeyinti ezintsha ezizicocayo ezikhusela ukungcola zisebenzisa i-nanotechnology ukuphucula amandla azo okuthintela ukungcola kunye nokusebenza kwazo ngokutshintsha ulwakhiwo lwe-microscopic yengubo. Kwixesha elizayo, iipeyinti ezizicocayo ezikhusela ukungcola kulindeleke ukuba zidlale indima enkulu kwicandelo lobunjineli bolwandle kwaye zinike inkxaso enamandla kuphuhliso lweshishini lolwandle.
Iimpawu eziphambili
Thintela izinto eziphilayo zaselwandle ekubeni zingonakalisi ezantsi kwenqanawa, ugcine ezantsi zicocekile; Yenza ukupolisha ngokuzenzekelayo nangokukhawuleza ukunciphisa uburhabaxa ezantsi kwenqanawa, ngesiphumo esihle sokunciphisa ukurhuqa; Ayinazo izibulali-zinambuzane ezisekelwe kwi-organotin, kwaye ayinabungozi kwimeko-bume yolwandle.
indawo yesicelo
Isetyenziselwa iindawo ezingaphantsi kwamanzi ezantsi kwenqanawa kunye nezakhiwo zolwandle, ithintela izinto eziphilayo zaselwandle ukuba zinganamatheli. Ingasetyenziswa njengepeyinti yokulungisa ethintela ukungcola ezantsi kweenqanawa ezisebenza kuhambo lwehlabathi kunye nokufika kwixesha elifutshane.
ukusebenzisa
Iimfuno zobugcisa
- Unyango lomphezulu: Zonke iindawo kufuneka zicoceke, zome kwaye zingangcolisi. Zifanele zihlolwe kwaye ziphathwe ngokuhambelana ne-ISO8504.

Amanqaku Okunika Ingqwalasela
Olu phawu luqulathe amasuntswana e-pigment, ngoko ke kufuneka luxutywe kakuhle kwaye luxutywe ngaphambi kokuba lusetyenziswe. Ubukhulu befilimu yepeyinti ethintela ukungcola bunempembelelo enkulu kwisiphumo sokuchasana nokungcola. Ke ngoko, inani leeleya zokuchasana alinakuncipha kwaye isinyibilikisi akufuneki songezwe ngokungacwangciswanga ukuqinisekisa ubukhulu befilimu yepeyinti. Impilo noKhuseleko: Nceda uqaphele imiqondiso yesilumkiso kwisikhongozeli sokupakisha. Sebenzisa kwindawo enomoya ococekileyo. Musa ukuphefumla inkungu yepeyinti kwaye uphephe ukudibana nolusu. Ukuba ipeyinti itshiza eluswini, hlambulula ngoko nangoko ngesixhobo sokucoca esifanelekileyo, isepha namanzi. Ukuba itshiza emehlweni, hlambulula ngamanzi amaninzi kwaye ufumane unyango ngoko nangoko.
