Solvent 646: nokurondedzerwa, GOST, akafanana

Solvent 646 kunoshanda chaizvo yezvisikwa solvent, akagadzirirwa kushandiswa paunenge uchishanda zvakasiyana pendi. Pamusana it unhani pashure nokuomesa Wana mamwe chivheneke. Munyaya ino uchadzidza:

- inova solvent 646;

- rwokugadzira nokurondedzerwa;

- Standard, zvinodiwa izvo yakafanana.

General zvechadenga solvent

Solvent mugwaro 646 - a segirazi Hauoneki mvura (dzimwe nguva vangava yellowish tint), dzinoratidzwa chaicho kunhuwa. solvent arambe achirema ndiyo 0,87 magiramu muzana cubic metres. Munoona, hazvishandi -oma uye haisi kuwedzera viscosity. It unopisa nomuzvarirwo panguva tembiricha kuti 403 madhigirii uye mamota pa 59 inegumi.

Kugadzirwa maererano zvinodiwa GOST 18188-172. The solvent inofanira yunifomu sezvamunoita. Hazvifaniri kuchengetwa turbidity uye delamination. Zvinonzi zvakare haana kubvumira kuvapo yakaturikwa inoramba iri mvura mvura.

Achibudiswa maindasitiri kavha mupurasitiki magirazi midziyo (hombodo) kuti hukuru siyana.

Solvent 646: nokurondedzerwa, mamiriro

Zviri remubatanidzwa wenyika kugadzikana Organic zvinhu. The solvent 646, maitiro iyo achienderana GOST 18188-72, inosanganisira zvinotevera pakugadzira:

• toluene - 50%;
• butanol - 15%;
• butyl acetate - 10%;
• ethyl spirt- 10%;
• acetone - 7%;
• ethylcellosolve - 8%.

Nokuda kwayo sezvamunoita, zviri kuonekwa zvikuru kushingaira Kuparadzwa zvinhu.

Solvent 646 nokurondedzerwa ndeinotevera:

• anokoshesa volatility kuti ethyl Eteri iri zvinobva 8 kusvika 15;
• Coagulation nhamba yakaenzana kanenge 35%;
• imwe iine acid nhamba isina anopfuura 0,06 MG Koh / d;
• mugove mvura (Fischer) kwete kupfuura 2%;
• pakubvisa matanho - pashure nokuomesa haina kuchengetwa pamberi zviitwe uye firimu nitroenamels dzinoratidzwa kwakanaka pasi pasina kuvapo echitema.

Where kushandisa?

Solvent 646 nokurondedzerwa kubvumira kushandiswa kushanda siyana pendi, kusanganisira nitrocellulose, melaninoamidnymi, glyptal, acrylic, epoxy. Rinoshandiswa kana sechinhu chirungiso kweShanduro izvi zvinhu kana kuti dilution avo vaida kusachinja-chinja pamberi kushandiswa. Uyewo, iyo reagent inowedzerwa filler uye lähikuva nokuda optimum workability, vachibvumira akakwana nokuputsa pemvura.

Mune zvimwe zviitiko, solvent ndiye R-646, izvo anoenderana nokurondedzerwa State, rinoshandiswa sechiratidzo mashoko siyana degreasing hukawanika kana yokushambidza midziyo (kuti optimize imwe muitiro).

Ndezvipi zvakanakira akasiyana solvent 646?

Pakati huru zvakanakira ari zvizivikanwe 646 solvent ndedzinotevera:

• zvizere pakawanda;
• mukuru kwazvo solvent simba;
• anopa mamwe Gloss coatings;
• nyore kushandisa;
• It hahubvi kana kunyorerana kutsva paganda pamusoro;
• Hazvina kuumba zara mafuta makwapa pamusoro kubatwa hukawanika;
• runopwa, akasasiya kunhuwidza.

Dosing

The solvent inowedzerwa pendi kana varnish zvidimbu zviduku kune kutsvakwa arambe achirema uye viscosity. Akatunhidzwa muvhenganiswa Saka tinofanira kuramba ruchiparira. Sezvo solvent ane refu basa, pandaishanda anofanira kungwarira zvikuru kwete Anotadzira rezasi rukoko unhani.

Safety patinoungana kushanda solvent

Fanira kuitwa mudzimba pamwe kufefetedza zvakanaka, nokuti pfuma ndiyo chepfu (semhosva nechetatu boka ngozi). Uyezve, kana uchishanda solvent mavanga 646 kushandiswa zvakadai PPE somunhu unomubatsira kufema uye magiravhusi. Zvinonzi Dzakamukurudzirawo kushandisa kuchengeteka magirazi.

Kana mutumwa akanga munzvimbo ganda, inofanira kubatwa nemvura (inodziya) nesipo. Kana neVadzidzi mucous Kamudzira weziso pashure Washing vanofanira kubvunza chiremba.

Yandakapiwa solvent chinhu zvinobata moto zvinhu, zvakakodzera kubata nayo kunyatsofunga uye pasi hapana ezvinhu hatibvumiri akazaruka moto, Masasaradzi uye kusvuta pedyo Matangi pamwe reagent.

How pandingaunganidzira?

The solvent yaichengetwa mumudziyo zvakasimba Akanyatsovharwa. Uyezve, pamwe reagent midziyo inofanira kuchengetedzwa pamusoro mwando, yakananga chezuva uye nokupisa. Hamungaendi chokudziya mano chaipo pedyo solvent mumagaba.

The garandi Nguva okuchengetera (sezvo mashoko vaburitsi) kubva musi gadzira ndiwo mwedzi 12, iyo inoita mabhizimisi kutenga zvigadzirwa izvi akawanda.

The tembiricha tsika panguva iyo solvent inochengeterwa, vari kuwanda kubva kubvisa 40 kuwedzerazve 40 cant.
