Hniav PF-133 (24 Duab): Cov Yam Ntxwv Tshwj Xeeb Thiab Ntom Ntawm Cov Muaj Pes Tsawg Leeg, GOST Thiab Daim Ntawv Pov Thawj Ntawm Kev Ua Raws, Kev Siv Ib 1 M2 Thiab Thaj Tsam

Kev pleev xim tsis yog txheej txheem yooj yim. Kev saib xyuas ntau yuav tsum tau them rau qhov uas yuav tsum tau npog nrog. Cov tsev tsim khoom lag luam muaj ntau yam xim thiab cov kua roj vanish. Kab lus no yuav tsom mus rau PF-133 txha hniav laus.

Cov yam ntxwv tseem ceeb thiab thaj tsam

Txhua yam xim thiab cov kua roj vanish yuav tsum muaj daim ntawv pov thawj ntawm kev ua raws. PF-133 cov xim pleev xim sib raug rau GOST 926-82.

Thaum yuav khoom, nco ntsoov nug tus muag khoom rau daim ntawv no.

Qhov no yuav ua rau koj ntseeg siab tias koj tab tom yuav cov khoom lag luam zoo thiab ntseeg tau. Txwv tsis pub, koj pheej hmoo tsis tau txais yam koj xav tau. Qhov no yuav tsis tsuas yog rhuav tshem qhov ua tiav ntawm txoj haujlwm, tab sis kuj tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv.

Cov nplaum ntawm chav kawm no yog sib xyaw ntawm cov xim thiab cov tshuaj txhuam hauv cov kua roj alkyd. Ib qho ntxiv, cov kuab tshuaj organic tau ntxiv rau qhov muaj pes tsawg leeg. Lwm yam tshuaj ntxiv raug tso cai.

Kev qhia tshwj xeeb:

• tsos tom qab ua kom qhuav - ib homogeneous txawm tias zaj duab xis;
• lub xub ntiag ntawm ci - 50%;
• muaj cov tshuaj tsis hloov pauv - ntawm 45 txog 70%;
• lub sijhawm ziab ntawm qhov kub ntawm 22-25 degrees yog tsawg kawg 24 teev.

Xav txog cov yam ntxwv saum toj no, peb tuaj yeem hais tias cov khoom siv tsis haum rau txhua hom saum npoo. Feem ntau, cov xim no yog siv los npog cov hlau thiab cov khoom ntoo. Cov hniav yog zoo meej rau pleev xim rau lub tsheb thauj khoom, ntim rau thauj khoom thauj.

Nws raug txwv tsis pub siv cov khoom raws li txheej txheej ntawm cov tsheb txias txias, nrog rau cov tshuab ua liaj ua teb uas raug rau huab cua cuam tshuam.

Nws yog qhov tsim nyog hais txog qhov tshwj xeeb ntawm cov hniav txhaws uas tiv taus huab cua sib txawv . Tsis tas li, cov xim tsis ntshai kis tau cov roj thiab cov xab npum. Cov hniav txha hniav laus tau thov raws li txoj cai muaj lub neej nruab nrab ntawm 3 xyoos. Qhov no yog lub sijhawm ntev, vim tias cov xim tuaj yeem tiv taus qhov hloov pauv kub, thiab tseem tsis ntshai nag thiab daus.

Kev npaj nto

Qhov saum npoo yuav tsum tau lo nrog txha hniav laus yuav tsum tau ua tib zoo npaj. Qhov no yuav ua kom lub neej muaj xim ntau ntxiv.

Kev npaj cov nplaim hlau:

• cov hlau yuav tsum tsis txhob xeb, tsis muaj impurities thiab muaj cov qauv sib xws kom ci;
• txhawm rau txhim kho qhov saum npoo, siv cov primer. Nws tuaj yeem yog cov txheej txheem rau hlau ntawm PF lossis GF chav kawm;
• yog tias txheej hlau muaj cov nplaim txig txig, tom qab ntawd cov xim tuaj yeem thov tam sim.

Kev npaj cov ntoo hauv tsev:

• Thawj qhov uas yuav tsum tau ua yog txiav txim siab yog tias ntoo tau pleev xim rau yav dhau los. Yog tias yog, tom qab ntawd nws yog qhov zoo dua los tshem cov xim qub, thiab ntxuav cov roj thiab av.
• Ua tiav kev ua nrog cov ntawv xuab zeb, thiab tom qab ntawd nqus kom huv los ntawm hmoov av.
• Yog tsob ntoo tshiab, nws yog qhov zoo dua los siv cov ziab kom qhuav. Qhov no yuav pab cov xim kom du dua thiab tseem muab cov nplaum ntxiv rau cov khoom.

Cov kws tshaj lij qhia kom tsis txhob siv cov kuab tshuaj hnyav, cawv daws teeb meem thiab roj av rau qhov degreasing.

Daim ntawv thov txheej txheem

Kev thov pleev xim rau saum npoo tsis yog txheej txheem nyuaj, tab sis nws yog ib qho tseem ceeb uas yuav tsum ua tiag. Do cov xim kom huv ua ntej pib ua haujlwm. Nws yuav tsum yog khaub ncaws. Yog tias muaj pes tsawg leeg tuab, tom qab ntawd ua ntej siv, cov xim tau diluted, tab sis tsis ntau dua 20% ntawm tag nrho cov khoom sib xyaw.

Cov nplaum tuaj yeem siv rau ntawm huab cua kub tsawg kawg 7 thiab tsis tshaj 35 degrees. Cov av noo yuav tsum tsis pub dhau qhov pib ntawm 80%.

Cov txheej yuav tsum tau thov ntawm qhov tsawg kawg 24 teev ntawm huab cua kub ntawm +25 degrees. Tab sis qhov ziab saum npoo kuj tseem ua tau ntawm 28 degrees. Hauv qhov no, lub sijhawm tos tau raug txo mus rau ob teev.

Cov xim tha xim tuaj yeem ua tiav hauv ntau txoj hauv kev:

• txhuam;
• siv rab phom tsuag - tsis muaj cua thiab muaj cua;
• dav hlau pouring ntawm qhov chaw;
• siv electrostatic txau.

Qhov ntom ntawm txheej txheej thov nyob ntawm seb koj xaiv txoj kev twg. Lub denser txheej, tsawg dua lawv tus lej yuav.

Noj

Kev siv cov nplaum yog nyob ntawm seb qhov txheej txheem ua tiav, dab tsi yog siv rau kev pleev xim, qhov kub thiab txias. Ib qho tseem ceeb yog qhov sib xyaw ua ke li cas.

Rau kev txau, cov xim yuav tsum tau ua kom nyias nrog cov dab dawb . Qhov hnyav ntawm qhov hnyav yuav tsum tsis pub tshaj 10% ntawm tag nrho cov xim ntawm cov xim.

Yog tias pleev xim ua tiav nrog cov menyuam lossis txhuam, tom qab ntawd cov tshuaj hnyav yog ib nrab, thiab cov tshuaj nws tus kheej yuav ntom thiab du dua ntawm qhov chaw.

Qhov pom zoo tuab ntawm ib txheej yog 20-45 microns, tus lej ntawm txheej yog 2-3. Qhov nruab nrab xim siv rau 1 m2 yog los ntawm 50 txog 120 grams.

Kev ruaj ntseg ntsuas

Tsis txhob hnov qab txog kev ntsuas kev nyab xeeb. Enamel PF-133 hais txog cov khoom siv sib txuas tau yooj yim, yog li tsis txhob ua ib qho haujlwm ze ntawm qhov chaw tua hluav taws.

Kev ua haujlwm yuav tsum ua tiav hauv thaj chaw uas muaj cua nkag tau zoo hauv hnab looj tes roj hmab thiab lub tshuab ua pa. Nws yog ib qho tseem ceeb kom tsis txhob kov cov tawv nqaij thiab ua pa. Khaws cov xim nyob rau hauv qhov chaw txias, tsaus, nyob deb ntawm menyuam yaus.

Yog tias koj ua raws txhua txoj cai siv saum toj no, koj yuav tau txais txiaj ntsig uas yuav ua rau koj nyob ntev.

Cov ntsiab lus ntawm txheej txheej txheej PF-133 tuaj yeem pom hauv cov vis dis aus hauv qab no.
