Hnyav 646: specifications, GOST, muaj pes tsawg leeg

Hnyav 646 yog zoo heev universal hnyav, tsim rau siv thaum ua hauj lwm nrog ntau xim. Ua tsaug rau nws cov txheej tom qab kom qhuav tau ntxiv ci. Nyob rau hauv no tsab xov xwm koj yuav kawm txog:

- uas yog ib tug hnyav 646;

- kev specifications;

- Standard, yuav tsum uas nws sau raws nkaus Ii.

General cov yam ntxwv ntawm cov kuab

Hnyav qib 646 - ib tug pob tshab tsis muaj kob kua (nyob rau hauv tej rooj plaub tej zaum yuav muaj ib tug yellowish tint), yus muaj los ntawm ib qho kev tsis hnov tsw. kuab ceev yog 0,87 grams tauj ib cubic meters. Saib, nws tsis khov thiab tsis nkag mus rau hauv viscosity. Nws ignites nthawv ntawm ib tug kub ntawm 403 degrees thiab boils ntawm 59 degrees.

Manufactured nyob rau hauv raws li cov uas yuav tsum tau ntawm GOST 18188-172. Cov kuab yuav tsum tau muaj ib tug uniform muaj pes tsawg leeg. Nws yuav tsum tsis txhob muaj cai turbidity thiab delamination. Nws kuj tsis tau tso cai muaj cov tshem tawm hais nyob rau hauv cov kua.

Ua nyob rau hauv industrial ntim rau hauv hnab yas thiab iav ntim (fwj) ntawm ntau ntau thiab tsawg.

Hnyav 646: specifications, qauv

Nws yog ib tug compound ntawm volatile organic tshuaj. Cov kuab 646, yam ntxwv ntawm cov uas sib nrog GOST 18188-72, muaj xws li cov nram qab no cov khoom xyaw:

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

Vim nws muaj pes tsawg leeg, nws yog suav tias yog yuav tsum tau cov tshaj cum dissolving khoom.

Hnyav 646 specifications yog raws li nram no:

• qhov tseem ceeb volatility ntawm ethyl ether nyob rau hauv ntau ntawm 8 rau 15;
• Coagulation tooj sib npaug zos rau tsawg kawg 35%;
• ib acid tooj tsis ntau tshaj 0,06 mg Koh / g;
• feem ntawm cov dej (Fischer) tsis ntau tshaj li 2%;
• diluting txiav txim - tom qab kom qhuav yog tsis pom tus xub ntiag ntawm ntxuav hniav dawb thiab zaj duab xis nitroenamels yus muaj los ntawm ib tug du nto tsis muaj cov stains.

Qhov twg thov li cas?

Hnyav 646 specifications cia siv mus ua hauj lwm nrog ib tug ntau yam ntawm cov xim tsev, xws li nitrocellulose, melaninoamidnymi, glyptal, acrylic, epoxy. Nws yog siv yog raws li ib tug additive nyob rau hauv qhuav ntawm cov ntaub ntawv los yog mus rau lawv cov dilution mus rau lub yam taub hau ua ntej yuav siv. Tsis tas li ntawd, lub reagent yog ntxiv rau cov tub lim thiab primer rau optimum workability, uas zoo kawg nkaus leveling qhov chaw.

Nyob rau hauv tej rooj plaub, lub kuab yog R-646, uas sib tau specifications XEEV, yog siv raws li ib tug cov ntaub ntawv uas rau ntau yam degreasing chaw los yog kev ntxuav khoom (optimize ib tug txheej txheem).

Yuav ua li cas yog qhov zoo sib txawv ntawm cov kuab 646?

Ntawm cov ntsiab zoo ntawm lub hom 646 kuab yog cov nram qab no:

• tsiag ntawv versatility;
• Heev siab kuab hwj chim;
• muab ntxiv gloss coatings;
• yooj yim rau siv;
• Nws tsis yog nyob rau hauv cov ntaub ntawv ntawm kev sib cuag kub nyhiab ntawm daim tawv nqaij nto;
• Nws tsis tsim greasy me ntsis rau ntawm kho chaw;
• suab, tawm hauv tsis muaj tsis hnov tsw.

dosing

Cov kuab yog ntxiv rau cov xim muaj hlau los yog cov kua roj vanish nyob rau hauv daim me me mus rau lub kev kawm ceev thiab viscosity. Bred sib tov yog li yuav tsum lossi stirring. Txij li thaum lub kuab muaj ib tug high kev ua si, thaum ua hauj lwm nrog nws yuav tsum tau tshwj xeeb tshaj yog ceev faj tsis txhob lwj sab txheej txheej.

Kev Nyab Xeeb ceev faj thaum ua hauj lwm nrog solvent

Yuav tsum tau muab nqa tawm nyob rau hauv cov chav nrog zoo qhov cua, vim hais tias cov tshuaj yeeb dej caw yog tshuaj lom (dej num raws li ib tug thib peb hauv chav kawm ntawv ntawm kev txaus ntshai). Nyob rau hauv tas li ntawd, thaum ua hauj lwm nrog ib tug hnyav tias 646 yuav tsum tau siv xws PPE raws li ib tug qhov ncauj thiab hnab looj tes. Nws kuj pom zoo kom siv tsom iav qhov muag.

Yog hais tias tus neeg saib xyuas yog nyob rau hauv lub cheeb tsam ntawm daim tawv nqaij, nws yuav tsum tau kho nrog dej (sov) nrog xab npum. Nyob rau hauv cov ntaub ntawv ntawm kev sib cuag nrog lub txheej membrane ntawm lub qhov muag tom qab ntxuav yuav tsum tau nrog ib tug kws kho mob.

Muab hais tias lub kuab yog ib tug flammable khoom, nws yog tsim nyog los leg nws zoo zoo thiab nyob rau hauv tsis muaj tej yam tsis pub qhib nplaim taws, sparks thiab haus luam yeeb nyob ze ntawm lub tso tsheb hlau luam nrog lub reagent.

Yuav ua li cas cia?

Cov kuab twb khaws cia nyob rau hauv ib tug nruj nreem kaw txog ntsha. Tsis tas li ntawd, nrog rau cov reagent ntim yuav tsum tau muaj kev tiv thaiv tiv thaiv humidity, ncaj qha tshav ntuj thiab kub. Koj muaj peev xwm tsis tawm tej yam cov cua kub pab kiag li lawm nyob rau hauv lub tam sim ntawd cheeb tsam ntawm kuab ntim.

Lub warranty lub sij hawm ntawm cia (raws li cov lus qhia producers) los ntawm hnub uas siv yog 12 lub hlis, uas enables cov lag luam los yuav cov khoom nyob rau hauv loj qhov ntau.

Qhov kub qhov tseem ceeb uas lub kuab yog cia rau, yog nyob rau hauv lub chav los ntawm Rho tawm 40 mus ntxiv 40 DEG.
