Ibikoresho byo kugabanya inganoIbikoresho bikoreshwa mu gusiga bishyirwa mu byiciro bitandukanye by’ibintu bivanze, aside acrylic, silicone, polimeri za fluorocarbon na acetate ya cellulose. Bitewe n’imiterere yabyo yo hasi y’ubuso, ibintu bipima ubunini ntibifasha gusa gusiga ku rugero, ahubwo bishobora no guteza ingaruka mbi. Mu gihe cyo kubikoresha, ikintu cy’ingenzi kigomba kwitabwaho ni ingaruka mbi z’ibintu bipima ubunini ku miterere yo kongera gusiga no kurwanya gucika kw’ubugari bw’ubugari, kandi niba ibintu bipima ubugari byatoranijwe bigomba kugeragezwa binyuze mu igerageza.

1. Uburyo bwo kugabanya ibinyabutabire bivanze

Muri make igizwe n'ibinyabutabire bihumura neza bya hydrocarbon, ketone, esters cyangwa ibinyabutabire byiza cyane by'amatsinda atandukanye y'imikorere, hamwe n'ibinyabutabire bihumura cyane. Mu gutegura no gukoresha, hagomba kwitabwaho igipimo cyabyo cyo guhindagurika, uburinganire bw'ihindagurika ry ...

Ubu bwoko bw'ibikoresho byo kugorora ingano bubereye gusa mu kunoza inenge zo kugorora ingano (nk'igabanuka, kwera, no kugaragara nabi) guterwa no kuma vuba cyane kw'ikintu cyo gupfuka no gushonga nabi kw'ibikoresho by'ibanze. Igipimo muri rusange ni 2% ~ 7% by'irangi ryose. Bizongera igihe cyo kuma cy'igipfuka. Ku bikoresho byo kumisha ubushyuhe bw'icyumba (nk'irangi rya nitro) bishobora kugwa iyo bishyizwe ku ruhande rw'imbere, ntibifasha gusa mu kugorora ingano, ahubwo binafasha kunoza imiterere y'urumuri. Mu gihe cyo kumisha, bishobora kandi gukumira utubumbe tw'ibinyabutabire n'imyobo y'ibinyabutabire biterwa no guhumeka vuba cyane kw'ikintu cyo gupfuka ingano. Cyane cyane iyo bikoreshejwe mu bihe by'ubushyuhe bwinshi n'ubushuhe bwinshi, bishobora kubuza ubuso bw'irangi kuma mbere y'igihe, bigatanga umuyoboro umwe wo guhindagurika kw'ibinyabutabire, kandi bikarinda ko habaho igihu cy'umweru mu irangi rya nitro. Ubu bwoko bw'ibikoresho byo kugorora ingano bukoreshwa hamwe n'ibindi bikoresho byo kugorora ingano.

2. Ibikoresho byo gupima acrylic

Ubu bwoko bw'ibikoresho byo kunganya ahanini ni copolymer ya esters za acrylic. Ibiranga byabwo ni ibi bikurikira:

(1) Esta ya aside acrylic itanga imikorere y'ibanze ku buso;

(2) Byayo−COOH,−OH, kandi−NR ishobora gufasha guhindura uburyo imiterere ya alkyl ester ihura;

(3) Uburemere bwa molekile bufitanye isano itaziguye n'imikorere ya nyuma yo gukwirakwira. Guhuza neza n'imiterere y'uruhererekane rwa polyacrylate ni ibintu bikenewe kugira ngo habeho uburyo bukwiye bwo kunganya. Uburyo bushoboka bwo kunganya bugaragara cyane cyane mu cyiciro cya nyuma;

(4) Igaragaza ubushobozi bwo kurwanya ifuro no gukurura ifuro muri sisitemu nyinshi;

(5) Igihe cyose hari umubare muto w'amatsinda akora (nka -OH, -COOH) mu gikoresho cyo kugabanya ubushyuhe, ingaruka ku kongera ubushyuhe ntizigaragara, ariko haracyari amahirwe yo kugira ingaruka ku kongera ubushyuhe;

(6) Hariho kandi ikibazo cyo guhuza polarity no guhuza, ibyo bikaba bisaba guhitamo igerageza.

3. Uburyo bwo kugabanya silicone

Silicone ni ubwoko bwa polymer ifite umuyoboro wa silicon-oxygen (Si-O-Si) nk'amagufwa n'amatsinda y'ibinyabuzima afatanye na atome za silicon. Ibinyabutabire byinshi bya silicone bifite imiyoboro yo ku ruhande ifite ingufu nke z'ubuso, bityo molekile za silicone zigira ingufu nke cyane z'ubuso n'imbaraga nke cyane z'ubuso.

Inyongeramusaruro ya polysiloxane ikoreshwa cyane ni polydimethylsiloxane, izwi kandi nka methyl silicone oil. Ikoreshwa cyane ni nk'umuti ugabanya uburemere bw'ibinyabutabire. Moderi nke z'uburemere bwa molekile zigira akamaro kanini mu gutuma ingano y'ibinyabutabire ihinduka, ariko bitewe n'ibibazo bikomeye byo guhuza, akenshi zikunze kugabanuka cyangwa kunanirwa kongera gupfuka. Kubwibyo, polydimethylsiloxane igomba guhindurwa mbere yuko ikoreshwa neza kandi mu buryo bwizewe mu gupfuka.

Uburyo bw'ingenzi bwo guhindura ni: silicone yahinduwe na polyether, alkyl n'indi silicone yahinduwe ku ruhande, silicone yahinduwe na polyester, silicone yahinduwe na polyacrylate, silicone yahinduwe na fluorine. Hari uburyo bwinshi bwo guhindura polydimethylsiloxane, ariko bwose bugamije kunoza uburyo ihura na coatings.

Ubu bwoko bw'umuti upima ubusanzwe ugira ingaruka zo kugena no gupima. Uhuye n'igitambaro ugomba kubanza kugeragezwa mbere yo gukoresha.

4. Ingingo z'ingenzi zo gukoresha

Hitamo ubwoko bukwiye: Hitamo ikintu gikwiye cyo kugabanya ubunini hakurikijwe ubwoko n'imikorere y'igitambaro. Mu guhitamo ikintu gikwiye cyo kugabanya ubunini, imiterere yacyo n'imiterere yacyo ndetse n'uko gihuye n'igitambaro ubwacyo; muri icyo gihe, ibintu bitandukanye byo kugabanya ubunini cyangwa ibindi binyongerwa akenshi bikoreshwa hamwe kugira ngo bihuze ibibazo bitandukanye.

Witondere ingano y’inyongera: kongeramo cyane bizatera ibibazo nko kugabanuka no kugwa ku buso bw’igitambaro, mu gihe kongeramo bike cyane bitazagera ku ngaruka zo kungana. Ubusanzwe, ingano y’inyongera igomba kugenwa hashingiwe ku buryo igitambaro gipima ubukana n’ibisabwa kungana, gukurikiza amabwiriza yo gukoresha reagent, no guhuza ibisubizo nyabyo by’ibizamini.

Uburyo bwo gusiga: Uburyo bwo gusiga ingano y'ipamba bugira ingaruka ku buryo bwo gusiga ingano. Mu gihe ukoresha igikoresho cyo gusiga ingano, ushobora gukoresha brushing, roller coating cyangwa spraying kugira ngo uhe umwanya wuzuye igikoresho cyo gusiga ingano.

Gukangura: Mu gihe ukoresha igikoresho cyo kunganya, irangi rigomba kubyutswa neza kugira ngo igikoresho cyo kunganya gikwirakwizwe neza mu irangi. Igihe cyo kunganya kigomba kugenwa hakurikijwe imiterere y'igikoresho cyo kunganya, muri rusange ntikirenza iminota 10.
