Nekumanikidzwa kwemitemo yekuchengetedza kwezvakatipoteredza, kuziva kwevanhu nezvekuchengetedzwa kwezvakatipoteredza kwave kuchivandudzwa nguva dzose;Kunyanya, mapurovhinzi nemaguta munyika yose akapa VOC emission limit standards;Kutsiva pendi nependi yemvura inogona kunyatsodzikisa zvinyorwa zveVOC mumhepo, nokudaro kuvandudza mamiriro ekunze ehutu, pendi yemvura, nezvimwewo.Industrial pendi inotora 70% yependi inoshandiswa gore rega rega.Nokudaro, kusimudzirwa kwependi yemvura ndiyowo nzira huru yeindasitiri yependi.
Nhanganyaya yemvura-based industrial pendi:
Pendi yemvura-yakavakirwa mumaindasitiri inonyanya kugadzirwa nemvura seyakanyungudika, inova rudzi rutsva rwezvakatipoteredza anti-ngura uye anti-corrosion pendi iyo yakasiyana nemafuta-based industrial pendi.Kushandiswa kwependi yemvura-yakavakirwa mumaindasitiri yakakura zvakanyanya, uye inogona kuonekwa kwese kwese mumabhiriji, zvivakwa zvesimbi, ngarava, electromechanical, simbi, etc. Nekuda kwekuchengetedza kwayo simba uye kuchengetedza kwezvakatipoteredza, hazvizokonzere kukuvadza uye kusvibiswa. muviri wemunhu uye zvakatipoteredza, uye inozivikanwa zvikuru pakati pevashandisi.
Kukamurwa kwependi yemvura-yakavakirwa mumaindasitiri:
Mhando dzakajairwa pamusika wependi wemvura-yakavakirwa maindasitiri anosanganisira acrylic anti-rust pendi, alkyd anti-rust pendi, epoxy anti-rust pendi, amino yekubheka pendi, nezvimwewo, inovhara simbi zvimiro, midziyo, mota, mekiniki zvikamu, matemplate Kukwira. mafuremu, mapaipi, mabhiriji emigwagwa mikuru, turera nemimwe minda;Kubva pakuvakwa, kune dip coating, spraying (kusanganisira electrostatic spraying), brushing, nezvimwe.
Kuita kwemvura-based industrial pendi:
(1) Kudzivirirwa kwezvakatipoteredza: kunhuhwirira kwakaderera uye kusvibiswa kwakaderera, hapana zvinhu zvine chepfu uye zvinokuvadza zvinogadzirwa kusati kwavakwa uye mushure mekuvaka, izvo zvinonyatso zadzisa girinhi kuchengetedzwa kwezvakatipoteredza.
(2) Kuchengeteka: kusingabatike uye kusaputika, nyore kutakura.
(3) Zvishandiso zvekuputira zvinogona kucheneswa nemvura yepombi, izvo zvinoderedza zvakanyanya kushandiswa kwekuchenesa zvinonyungudutsa uye zvinonyatso kuderedza kukuvadzwa kwevashandi vekuvaka.
(4) Zviri nyore kuomesa uye ine yakasimba coating adhesion, iyo inovandudza kushanda zvakanaka uye inoderedza mari yebasa.
(5) Yakasiyana-siyana yekushandisa: mota, ngarava, magidhi, kugadzira michina, midziyo, njanji, mabhiriji, mashizha emagetsi emhepo, zvivakwa zvesimbi uye mamwe maindasitiri.
Basa re primer uye topcoat:
Mushure mekunge iyo primer yaiswa, iyo nano-scale primer resin ichakurumidza kupinda mune imwe kudzika pamwe chete nema micropores e substrate.Mushure mekuoma, resin ichavhara substrate, iyo inonyanya kukosha pakudzivirira ngura;iyo yepakati yekuputira inonyanya kuita basa rekuchinja uye kuwedzera kukora kwefirimu repende.Basa;topcoat inonyanya kushandiswa kuwana iyo yekupedzisira yekubikira mhedzisiro, kusanganisira gloss, kunzwa, kudzivirira, nezvimwe, uye pakupedzisira inoumba yekupedzisira yekubikira chimiro pamwe neiyo yekutanga coating.
Manotsi ekuvaka:
(1) Zvinorambidzwa zvachose kubata nezvinhu zvine mafuta.Sanisa zvakanaka usati washandisa.Inogona kucheneswa zvakafanira nemvura yemupombi zvinoenderana nezvinodiwa chaizvo, asi kazhinji kuwedzera 0-10% mvura ndiyo yakanyanya kunaka.
(2) Brush coating, roller coating, spray coating uye dip coating zvese zvinogamuchirwa, uye tembiricha yekuvaka inogona kunge iri ≥0℃.
(3) Isati yavakwa, mafuta epamusoro, marara ejecha uye yakasununguka ngura inoyangarara inofanira kubviswa.
(4) Tembiricha yekuchengetera ≥0 ℃, chengeta munzvimbo inotonhorera uye yakaoma, kudzivirira kutonhora uye kubuda kwezuva.
(5) Mumamiriro okunze akaipa akadai semvura nechando, kuvaka hakugone kuitirwa kunze.Kana kuvakwa kwave kuchiitwa, firimu yepende inogona kudzivirirwa nekuifukidza ne tarpaulin.
