Cov kuab tshuaj yog qhov tshwj xeeb muaj pes tsawg leeg muaj pes tsawg leeg ua raws cov organic lossis cov khoom tsis haum. Nyob ntawm tus yam ntxwv ntawm cov kuab tshuaj tshwj xeeb, nws tau siv rau ntxiv rau cov xim lossis cov khoom siv ua kua. Tsis tas li, cov khoom sib xyaw hnyav tau siv los tshem tawm cov xim los ntawm cov xim thiab cov kua roj vanish lossis ua kom cov tshuaj muaj kab mob sib kis nyob rau ntau qhov chaw.
Peculiarities
Cov kuab tshuaj tuaj yeem tsim los ntawm ib lossis ntau yam khoom. Tsis ntev los no, cov qauv sib xyaw ua ke tau txais cov neeg nyiam tshaj plaws.
Feem ntau cov kuab tshuaj (thinners) muaj nyob hauv cov kua. Lawv cov yam ntxwv tseem ceeb yog:
- tsos (xim, qauv, sib xws ntawm cov muaj pes tsawg leeg);
- qhov sib piv ntawm cov dej kom ntau npaum li lwm cov khoom;
- ntom ntawm slurry;
- volatility (volatility);
- qib ntawm toxicity;
- acidity;
- coagulation naj npawb;
- qhov sib piv ntawm cov khoom organic thiab inorganic;
- nplaim taws.
Kev sib xyaw ua ke tau siv dav hauv ntau yam kev lag luam (suav nrog tshuaj lom neeg), ntxiv rau hauv kev siv tshuab kho tshuab. Ib qho ntxiv, lawv tau siv hauv kev tsim cov khau thiab tawv khoom, hauv kev kho mob, kev tshawb fawb thiab kev lag luam.
Hom kev sau ua ke
Nyob ntawm qhov tshwj xeeb ntawm kev ua haujlwm thiab hom nto uas siv cov kuab tshuaj, kev sib sau tau muab faib ua ob peb pawg loj.
Cov tshuaj pleev rau cov xim pleev xim. Cov no yog cov sib xyaw ua kom me me uas tau siv los ntxiv rau cov xim tha xim txhawm rau txhim kho lawv cov khoom. Turpentine, roj av, dawb ntsuj plig feem ntau siv rau lub hom phiaj no
- Kev sib xyaw npaj rau kev dilution ntawm cov xim bituminous thiab cov xim pleev xim raws li glyphthalic (xylene, hnyav).
- Cov kuab tshuaj rau cov xim PVC. Acetone feem ntau yog siv los ua kom cov xim zoo li no.
- Cov kua nplaum rau cov nplaum thiab dej raws cov xim.
- Cov tshuaj hnyav hnyav ua rau siv hauv tsev.
Nta ntawm cov muaj pes tsawg leeg ntawm R-647
Qhov nrov tshaj plaws thiab siv dav rau ntau hom haujlwm ntawm lub sijhawm yog R-647 thiab R-646 nyias nyias. Cov kuab tshuaj no zoo sib xws hauv cov muaj pes tsawg leeg thiab zoo ib yam hauv cov khoom. Ib qho ntxiv, lawv yog cov uas pheej yig tshaj plaws ntawm lawv cov nqi.
Hnyav R-647 tau txiav txim siab tsis txhoj puab heev thiab ntxim rau ntawm qhov chaw thiab cov khoom siv . (vim tias tsis muaj acetone hauv qhov muaj pes tsawg leeg).
Nws siv yog qhov pom zoo hauv cov xwm txheej uas yuav tsum tau ua kom zoo dua qub thiab ua kom zoo rau ntawm qhov chaw.
Feem ntau qhov sib xyaw ntawm cov khoom lag luam no tau siv rau ntau yam kev ua haujlwm ntawm lub cev thiab rau xim tsheb.
Daim ntawv thov thaj tsam
R-647 daws tau zoo nrog txoj haujlwm ntawm kev nce viscosity ntawm cov tshuaj thiab cov khoom siv uas muaj nitrocellulose.
Thinner 647 tsis ua puas rau qhov chaw uas tsis muaj zog tiv taus tshuaj lom , suav nrog yas Vim qhov ua tau zoo no, nws tuaj yeem siv rau kev txo qis, tshem tawm cov cim thiab cov xim los ntawm cov xim thiab cov kua roj vanish (tom qab evaporation ntawm qhov muaj pes tsawg leeg, zaj duab xis tsis tig dawb, thiab khawb thiab ntxhib ntawm qhov saum npoo tau pom zoo). siv rau ntau yam haujlwm.
Tsis tas li, cov kuab tshuaj tuaj yeem siv los dilute nitro enamels thiab nitro varnishes. Thaum ntxiv rau cov xim thiab cov xim sib xyaw ua ke, cov tshuaj yuav tsum tau sib xyaw tas li, thiab cov txheej txheem sib xyaw ncaj qha yuav tsum tau ua nruj me ntsis hauv qhov sib piv uas tau qhia hauv cov lus qhia. Thinner R-647 feem ntau siv nrog cov xim thiab cov xim hauv qab no: NTs-280, AK-194, NTs-132P, NTs-11.
R-647 tuaj yeem siv tau hauv lub neej txhua hnub (raug rau txhua qhov kev tiv thaiv kev nyab xeeb).
Cov khoom siv thiab cov yam ntxwv ntawm cov tshuaj hnyav ntawm qib R-647 raws li GOST 18188-72:
- Cov tsos ntawm kev daws teeb meem. Cov muaj pes tsawg leeg zoo li cov kua ua kua pob tshab nrog cov qauv sib xws yam tsis muaj qhov tsis huv, suav nrog lossis tso dej. Qee zaum qhov kev daws teeb meem yuav muaj xim daj me ntsis.
- Feem pua ntawm cov ntsiab lus dej tsis ntau dua 0, 6.
- Qhov ntsuas qhov ntsuas ntawm qhov muaj pes tsawg leeg: 8-12.

Kev nyab xeeb thiab kev ceev faj
Cov kuab tshuaj yog ib yam tshuaj tsis zoo thiab tuaj yeem cuam tshuam tsis zoo rau tib neeg lub cev. Thaum ua haujlwm nrog nws, nws yog ib qho tseem ceeb kom ua raws kev ceev faj thiab ntsuas kev nyab xeeb.
- Khaws rau hauv ib lub kaw kaw, kaw kom nruj, kom deb ntawm cov hluav taws thiab cov khoom siv cua sov. Nws kuj tseem tsim nyog kom tsis txhob nthuav tawm lub thawv ntim nrog qhov sib ntxiv kom ncaj qha tshav ntuj.
- Cov tshuaj hnyav, ib yam li lwm yam tshuaj hauv tsev, yuav tsum tau nyab xeeb thiab tsis pub menyuam yaus lossis tsiaj mus cuag.
- Kev nqus pa ntawm cov pa ua kom sib xyaw ntawm cov tshuaj hnyav yog qhov txaus ntshai thiab tuaj yeem ua rau lom. Hauv chav uas pleev xim lossis pleev xim rau sab nrauv, yuav tsum tso cua tawm lossis tso pa tawm ntau.
- Tsis txhob muab cov tshuaj hnyav rau hauv qhov muag lossis ntawm daim tawv nqaij. Kev ua haujlwm yuav tsum tau ua hauv hnab looj tes tiv thaiv roj hmab. Yog tias cov tawv nqaij tau txais ntawm qhov chaw qhib ntawm lub cev, koj yuav tsum tau ntxuav tam sim ntawd nrog rau cov dej kom ntau siv xab npum lossis daws cov tshuaj alkaline me ntsis.
- Kev nqus pa ntawm cov pa paug siab tuaj yeem ua rau lub paj hlwb puas tsuaj, cov hlab ntshav hauv nruab nrog cev, daim siab, lub plab zom mov, lub raum, cov hnoos qeev. Cov tshuaj tuaj yeem nkag mus rau hauv nruab nrog cev thiab lub cev tsis yog los ntawm kev nqus cov pa ncaj qha, tab sis kuj los ntawm qhov hws ntawm daim tawv nqaij.
- Yog tias muaj kev sib cuag nrog daim tawv nqaij ntev thiab tsis muaj lub sijhawm ntxuav, cov kuab tshuaj tuaj yeem ua rau daim tawv nqaij puas tsuaj thiab ua rau cov tawv nqaij ua rau tawv nqaij.
- Kev sib xyaw R-647 tsim cov tshuaj tua hluav taws peroxides yog tias sib xyaw nrog cov tshuaj oxidants. Yog li ntawd, cov kuab tshuaj yuav tsum tsis txhob raug cuam tshuam nrog nitric lossis acetic acid, hydrogen peroxide, tshuaj muaj zog thiab cov kua qaub sib xyaw.
- Kev sib cuag ntawm cov tshuaj nrog chloroform thiab bromoform yog hluav taws thiab tawg.
- Txau nrog cov kuab tshuaj yuav tsum zam, vim qhov no yuav sai sai mus rau qhov txaus ntshai ntawm huab cua muaj kuab paug. Thaum txau cov tshuaj muaj pes tsawg leeg, cov tshuaj yuav tuaj yeem ua rau hluav taws txawm tias nyob deb ntawm qhov hluav taws.
Koj tuaj yeem yuav R-647 cov tshuaj hnyav hauv cov khw muag khoom lossis hauv khw tshwj xeeb . Rau kev siv hauv tsev, cov tshuaj hnyav tau ntim rau hauv lub raj mis yas los ntawm 0.5 l. Txhawm rau siv ntawm qhov ntim ntau lawm, ntim tau nqa hauv cov fwj dej nrog ntim ntawm 1 txog 10 liv lossis hauv cov hlau loj.
Tus nqi nruab nrab rau R-647 hnyav yog li 60 rubles. rau 1 litre.
