Gucukumbura Ibikoresho nuburyo bwa Firime Zirinda

Firime ikingira aluminium ni formulaire ya firime polyethylene (PE) nka substrate, acide polyacrylic (ester) resin nkibikoresho byibanze byumuvuduko ukabije wumuvuduko, bifatanyijemo nibindi byongeweho bifata neza ukoresheje igifuniko, gukata, gupakira, nibindi bikorwa, the firime irinda iroroshye, hamwe nimbaraga nziza zifatika, byoroshye gukata, byoroshye gukuramo. Umuvuduko ukabije wumuti uhamye nibyiza kandi ntabwo bizagira ingaruka mbi kubicuruzwa byanditse.

Ingano yo gusaba: Ahanini ikoreshwa muburyo bwose bwa plastiki, isahani yimbaho ​​(urupapuro) kurinda hejuru yubutaka, nka PVC, PET, PC, PMMA isahani yamabara abiri, ikibaho cya UV ikibaho, ikirahure, nibindi bisahani mubitwara, kubika , no gutunganya, inzira yo kwishyiriraho nta byangiritse.

Imiterere nibintu bya firime ikingira

Filime ikingira muri rusange ni firime ikingira polyacrylate, firime irinda polyacrylate yuburyo bwibanze kuva hejuru kugeza hasi: urwego rwo kwigunga, icapiro, firime, igikoresho gifatika.

.

1. Filime

Nkibikoresho fatizo, firime ikozwe muri polyethylene nkeya (PE) na chloride polyvinyl (PVC). Gukuramo ibishishwa, kubumba inshinge, no guhumeka birashobora kuboneka. Nkuko polyethylene ihendutse kandi yangiza ibidukikije, 90% ya firime ikozwe muri polyethylene, hamwe nuburyo bwo guhanagura nkibintu byibandwaho. Hariho ubwoko bwinshi bwa polyethylene hamwe ningingo zitandukanye zo gushonga hamwe nubucucike.

2. Guteranya

Ibiranga colloid bigena urufunguzo rwibyiza nibibi bya firime ikingira. Filime ikingira ikoreshwa mu gufatira ibyiyumvo bifite ubwoko bubiri: ibishishwa bishingiye kuri polyacrylate bifata hamwe na polyacrylate yangiza amazi; bafite imiterere itandukanye.

Umuti ushingiye kuri polyacrylate

Amashanyarazi ashingiye kuri polyacrylate yumuti ni umusemburo kama nkuburyo bwo gushonga monry acrylic; colloid iragaragara cyane, viscosity yambere iracyari hasi, kandi irwanya cyane gusaza kumyaka igera kumyaka 10 iyo ihuye numucyo ultraviolet; colloid nayo izakira buhoro buhoro. Iyo firime imaze kuvurwa na corona, ibishishwa bya polyacrylate birashobora gutwikirwa neza nta primer. Ibikoresho bifata polyacrylate biraruhije kandi bifite amazi mabi, bityo gufunga firime birinda gukina buhoro; na nyuma yigitutu, gel hamwe nubuso bugomba kumanikwa ntibishobora kuboneka neza. Bishyizwe nyuma yiminsi 30 ~ 60, bizaba bihuye neza nubuso bugomba kumanikwa kugirango bigere kumurongo wanyuma, kandi gufatira kwanyuma bikunda kuba binini kuruta guhuza inshuro 2 ~ 3, gufatira hamwe firime ikingira, niba ibereye gukata uruganda rwibibaho, umukoresha wa nyuma ashwanyaguza firime mugihe ahari Birashobora kuba akazi gakomeye cyangwa ntigashobora gucika.

Amazi ashonga polyacrylate yometse

Amazi ashonga polyacrylate yifashisha amazi nkuburyo bwo gushonga monomer acrylic. Ifite kandi ibiranga ibishishwa bishingiye kuri polyacrylate, ariko colloid igomba kwirinda kugabanya umubyigano wumwuka wamazi no kwirinda kole zisigara. Ibihugu biri mu nzira y'amajyambere bikunze gukoresha koleoide kugirango ikore firime ikingira kuko ibishishwa byamazi ya polyacrylate bifata amazi byangiza ibidukikije kandi ntibikeneye ibikoresho byo kugarura ibintu.

3. Ibiranga colloid

Kwizirika

Yerekeza ku gihe iyo firime irinda hejuru yometse ku mbaraga zisabwa gukuramo. Imbaraga zifatika zifitanye isano nibikoresho bigomba gukoreshwa, igitutu, igihe cyo gukoreshwa, inguni, nubushyuhe mugihe cyo gukuramo firime. Nk’uko Coating Online ibivuga, muri rusange, hamwe no kwiyongera kwigihe nigitutu, imbaraga zifatika nazo zizamuka; gukingira firime kurinda birashobora kuzamuka cyane kugirango hatagira igisigisigi gisigara mugihe ushwanyaguza firime.Mubisanzwe, ibipimisho bipimwa mugupima dogere 180.

Ubumwe

Yerekeza ku mbaraga za colloid imbere, nka firime ikingira coloid cohesion igomba kuba ndende cyane; bitabaye ibyo, mugushwanyaguza firime ikingira, colloid izacika imbere, bivamo ibisigisigi. Gupima ubumwe: Filime ikingira izashyirwa hejuru yicyuma kitagira umwanda, kandi uburemere bwihariye buzamanikwa kuri firime ikingira kugirango hamenyekane igihe gikenewe kugirango ukureho firime ikingira uburemere. Niba imbaraga zifatika ziruta imbaraga zifatika, kuramo firime ikingira, kandi molekile zifatika zifitanye isano nubucuti zizacika, bikavamo gufatira hamwe.

Kwizirika

Ibi bivuga imbaraga zihuza hagati yifata na firime. Niba imbaraga zifatika zirenze imbaraga zo guhuriza hamwe, niba firime ikingira ikuweho, isano iri hagati ya molekile ifata na firime izacika, bikavamo gufatira hamwe.

UV Kurwanya

Ibikoresho bya polyacrylate birwanya UV, birinda polyacrylate ifata ibyuma birinda hamwe na UV stabilisateur; ni UV irwanya amezi 3 ~ 6. Gukoresha muri rusange ibikoresho byo kwigana ikirere kugirango hamenyekane imbaraga za UV za firime ikingira muguhindura ubukana bwimirasire yubushyuhe, hamwe no guhuza imihindagurikire y’ikirere buri masaha 3 y’ubushuhe bukabije n’amasaha 7 y’imishwarara ya ultraviolet ku ruziga rw’amasaha 50 y’ubushakashatsi ni bihwanye no hafi ukwezi gushira hanze.
