Gukoresha Cellulose Ether mugukuraho irangi

gukuramo amarangi

Gukuraho irangi ni umusemburo cyangwa paste ishobora gushonga cyangwa kubyimba firime ya coating, kandi igizwe ahanini nigishishwa gifite ubushobozi bukomeye bwo gushonga, paraffine, selile, nibindi.

Mu nganda zubaka ubwato, uburyo bwubukanishi nko guterura intoki, guturika amasasu, kumusenyi, amazi yumuvuduko mwinshi hamwe nindege zangiza cyane bikoreshwa mugukuraho imyenda ishaje. Nyamara, kuri aluminiyumu, uburyo bwubukanishi buroroshye gushushanya aluminiyumu, bityo rero nyamukuru Koresha umusenyi wohanagura, gusiga amarangi, nibindi kugirango ukureho firime ishaje. Ugereranije n'umucanga, gukoresha ibikoresho byo gukuraho amarangi kugirango ukureho firime ishaje irangi bifite ibyiza byumutekano, kurengera ibidukikije no gukora neza.

Ibyiza byo gukoresha amarangi ni byiza cyane, gukoresha ubushyuhe bwicyumba, kutangirika kwicyuma, kubaka byoroshye, nta mpamvu yo kongera ibikoresho, kandi ibibi ni uko gukuramo amarangi ari uburozi, guhindagurika, gutwikwa, kandi bihenze. Mu myaka yashize, hagaragaye ibicuruzwa bitandukanye byo kuvanaho amarangi, kandi no kuvanaho amarangi ashingiye ku mazi nabyo byakozwe. Gukuraho amarangi byakozwe neza, kandi ibikorwa byo kurengera ibidukikije byakomeje kunozwa. Ibicuruzwa bidafite uburozi, uburozi buke, nibidacanwa byafashe umwanya munini isoko rusange yo gukuraho amarangi.

Ihame ryo gukuraho amarangi no gutondekanya gukuraho amarangi

1. Ihame ryo gukuramo amarangi

Gukuraho amarangi ahanini bishingiye kumashanyarazi kama mugukuraho amarangi kugirango ashonge kandi yabyimbye firime nyinshi, kugirango agere ku ntego yo gukuraho firime ishaje ishaje hejuru ya substrate. Iyo kuvanaho irangi byinjiye mu cyuho cya polymer cyu gipande cya polymer, bizatera polymer kubyimba, kuburyo ingano ya firime ya coating izakomeza kwiyongera, hamwe nihungabana ryimbere ryatewe no kwiyongera kwubunini bwa coating polymer izacika intege hanyuma Amaherezo, gufatisha firime ya coating kuri substrate birasenyuka, kandi firime ya coating ikura kuva kumera nkibibyimba kugeza kubyimba impapuro, bigatuma firime yipfundikanya ikabyimba, bikangiza burundu gufatira kwa firime ya coater kuri substrate. , hanyuma amaherezo ya firime yatwikiriye. bisobanutse.

2. Gutondekanya gukuraho amarangi

Irangi risize amarangi rigabanyijemo ibyiciro bibiri ukurikije ibintu bitandukanye byakozwe na firime byavanyweho: kimwe gikozwe mumashanyarazi kama nka ketone, benzene, na ketone, hamwe na paraffin retarder retarder paraffin, ikunze kwitwa amavuta yo kwisiga, kandi ikoreshwa cyane muri Remove firime zishaje zishaje nkamavuta, alkyd na nitro. Ubu bwoko bwo kuvanaho amarangi bugizwe ahanini na solge organique ihindagurika, ifite ibibazo nkumuriro nuburozi, kandi bihendutse.

Ibindi ni chlorine ya hydrocarubone ikuramo amarangi yakozwe na dichloromethane, paraffin na selulose ether nkibice byingenzi, bikunze kwitwa kuvanaho irangi ryamazi, ahanini bikoreshwa mugukuraho epoxy asifalt, polyurethane, epoxy poly Yakize firime zishaje nka phthalamide cyangwa amino alkyd resin. Ifite irangi ryinshi ryo gukuraho irangi, uburozi buke no gukoresha mugari. Gukuraho irangi hamwe na dichloromethane nkigisubizo nyamukuru nacyo kigabanijwemo kuvanaho amarangi atabogamye (pH = 7 ± 1), kuvanaho irangi rya alkaline (pH> 7) no kuvanaho amarangi acide ukurikije itandukaniro ryagaciro ka pH.
