Okusayidi nthaka: ntchito, mapangidwe ndi ankaudaya njira

Nthaka woyera - ndi inki zochita kupanga zochokera okusayidi nthaka, zomwe osakaniza binders zosiyanasiyana (kuyanika mafuta, mafuta masamba) kupanga utoto woyera. anthu ochepa chabe amene akudziwa za makhalidwe ndi maonekedwe a okusayidi nthaka, kotero ife tiri m'nkhani idzayankha nkhani imeneyi.

makhalidwe a

Mu mawonekedwe woyera, mankhwala ali woyera mtheradi ndi pang'ono bluish kulocha. White odorless, ndipo akhoza kusakaniza bwino ndi amadzimadzi njira soda ndi ammonia. Iwo siziboola pansi ndipo musati deform mchikakamizo cha tizilombo ndi mabakiteriya. Chifukwa amatha kuyamwa chinyontho, iwo ayenera kusungidwa mu muli chatsekedwa.

Pa katundu zabwino mulinso zinthu monga:

• otsika-kawopsedwe;
• kukana dzuwa;
• kuwachepetsera ntchito;
• Ngakhale ndi mitundu yonse ya utoto;
• weathering kukana.

Komabe, iwo adzalandira katundu zoipa, monga akulimbana, Kuphunzira osauka ndipo sachedwa kutengera yambiri mafuta.

Pamene ntchito luso ngati katundu whiting ngati brittleness ndi luso kuphimba mipata, kuyambitsa chitsanzo chotani olembedwa ndi ntchito zawo, sikutheka pindani. Komanso ayenera kuwunika mavuto a chinsalu, chimene chingasinthe ndi kuwonjezeka chinyezi. Ndi psinjika wake woyera kapena mavuto akhoza kutha.

Mitundu ya okusayidi nthaka

Amabisa nthaka anawagawa zopangidwa ziwiri: BTS0 ndi BC1.

Zamgululi ataphimbidwa ndi chilemba BTS0, ntchito kupanga utoto, chikopa yokumba ndi mankhwala mphira. Komanso anawonjezera kuti abrasives ndi formulations simenti kwa mano.

White BC1 mtundu zimagwiritsa ntchito kupanga asibesitosi-simenti ndi penti, amene ntchito chokongoletsera malo mkati ndi kunja, osachepera - kwa kupanga zikopa yokumba ndi mphira yekha.

ntchito

Komanso, pali madera ena komwe woyera nthaka ntchito. ntchito yawo ndi mankhwala. Iwo ali mmodzi wa zigawo zina mafuta antiseptic ndi ufa. Iwo amagwiritsa ntchito kupanga mapulasitiki, labala pepala ndi galasi.

Payokha, nthaka woyera akhoza kuwasiyanitsa (woyera utoto) chopangidwa pamaziko a okusayidi nthaka kalasi A. The utoto lagawidwa mitundu ingapo, cholinga ntchito panja ndi m'nyumba. Mwa ichi mtundu wa utoto ndi zambiri yokongola mkati ntchito woyera nthaka MA 22, amene yodziwika ndi ntchito yapamwamba ndi chitetezo bwino moto.

Komanso lero wa okusayidi nthaka zimapangitsa yomanga anticorrosion utoto. White anawonjezera kuti nyimbo za fillers ndi zomatira zosiyanasiyana, ndi ntchito kupanga zoumbaumba.

Izo mukudziwa kuti pa kukonza nthaka woyera, linseed mafuta kuchepetsedwa ndi utoto kugwirizana, kungakhale impregnated nsalu chingwe, amene ntchito ngati zisindikizo mu mipope yamazinga kugwirizana madzi.

Zithunzi kubala okusayidi koyera nthaka, wopangidwa mwa particles wabwino kwambiri wa okusayidi nthaka, munali palibe kuda chitsulo ndi oxides patsogolo. Iwo translucent ndi ozizira kamvekedwe amasiyana pa chikalata inelastic filimu. Iwo ntchito zonse mitundu ya luso, monga iwo ndi kugonjetsedwa kwambiri pigment kuwala imene sasintha, ngakhale inks amene ali sulfure. Kawirikawiri oyeretsa utoto wofiira ndi cadmium anawonjezera kuti kusintha khalidwe lake.

Mafuta nthaka woyera

Izi zili okusayidi nthaka amene achotsa kapena mafuta linseed. Nthawi zambiri amatchedwa mafuta ndi ntchito kuteteza zitsulo nyumba kuchokera dzimbiri, ndiponso chifukwa chekeni nkhuni ndi pulasitala pamalo. Ndipo iwo ali oyenera kugwiritsa ntchito mkati ndi kunja.

Nthaka woyera mafuta ndi wabwino kubisala mphamvu, ndiye pamene ntchito pamwamba iwo kwathunthu kubisa mtundu wa ❖ kuyanika kale ntchito. Komanso, wokutira kulenga dzimbiri zosagwira ❖ kuyanika ndi kukana mkulu chinyezi ndi mpweya permeability.

njira kupenta

Nthaka woyera ntchito pulasitala ❖ kuyanika, zitsulo ndi pamalo matabwa.

Ntchito opangidwa ndi kuvala magolovesi, ndi pa awo kukhazikitsa ndi pakutha pa chipinda m'pofunika ventilate.

Akuyendera ndi utoto, amabisa, ngati gustotertyh ufa kuchepetsa masoka kuyanika mafuta, kuchuluka amene ayenera kukhala 18-25% ya misa okwana woyera ndipo kwambiri bwinobwino wosanganiza. Ngati ndi mafuta utoto, ndiyeno ngati kuli kofunikira kuwonjezera mzimu woyera kapena turpentine.

Pamwamba ayenera kukhala chisanadze kukonzekera:

• choyamba ndi kutsukidwa dothi, mafuta, fumbi, akale utoto (ngati chofunika). Izi zachitika ndi spatula ndi;
• ndiye putty ming'alu samveka ndi mphako;
• Pambuyo kupukuta pamwamba ntchito wopukutidwa ntchito sandpaper;
• Kenako ntchito kwa phunziroli ndi;
• Pambuyo pa phunziroli wauma chitani chekeni.

Kuchepetsa kumwa woyera kutsogolera, mafuta linseed tikulimbikitsidwa kuphimba pamwamba.

White umagwiritsidwa ntchito pa yosalala pamwamba youma ntchito utoto burashi , utsi mfuti kapena wodzigudubuza:

• burashi ntchito ankaudaya zinthu zabwino ndipo kali kakang'ono;
• Kuphunzira lalikulu ntchito burashi kapena wodzigudubuza;
• zosavuta kupenta ndondomeko umadutsa mfuti kutsitsi. Njira imeneyi zimathandiza kuti alenge ngakhale wosanjikiza ndi kuchitira malo kufikako.

chiwerengero cha zigawo kungakhale 1 kapena 2 malingana mukufuna. Aliyense wosanjikiza ambiri uphwetsa maola ngati firiji si chozama kupitirira + 20º C. kumwa woyera pa mzere umodzi ndi za 170-200 ga pa 1 sq. m.

wazolongedza

zosiyanasiyana ntchito ma CD. okusayidi nthaka akhoza mmatumba mu matumba (pulasitiki kapena pepala), pulasitiki kapena ng'oma matabwa, makatoni, plywood kapena chidebe chochuluka ndi zapamadzi anapanga matumba polyethylene, pepala kapena polyethylene, komanso chapadera zofewa muli disposable.

Transport ndi yosungirako

mankhwala Transport amaloledwa mitundumitundu zoyendera yokutidwa, kupatulapo wopangidwa yekha woyera, ankanyamula mu muli wapadera zofewa - iwo akhoza kusamutsidwa mu galimoto poyera ndi kusunga panja.

Koma okusayidi nthaka, mmatumba mu CD zina, iwo kusungidwa mu malo chatsekedwa, ndi kutentha kuyambira -40 ° C kwa 40 ° C. Iwo anayikidwa pa matabwa pallets stacks wa ku 3 mamita mkulu.
