Cov muaj pes tsawg leeg ntawm cov khoom tiav no muaj cov khoom xws li kaolin av nplaum thiab xuab zeb, nrog rau fireclay. Nws muaj kev tiv thaiv zoo rau cua sov. Withstands kub txog li 1300 degrees Celsius. Txawm li cas los xij, muaj qhov tsis zoo me me - ntau lub sijhawm yuav tsum tau ua kom muaj zog ntawm cov khoom.
About "Terracotta"
"Terracotta" yog dab tsi? Cov no yog cov tshuaj qhuav qhuav, npaj siv. Lawv yog siv los tso cov khoom uas tom qab ntawd yuav raug rau qhov kub thiab txias. Cov khoom lag luam zoo thiab lub Hoobkas ntawm lub tuam txhab no muaj ob hom ntim - cov no yog 20- thiab 25-kg hnab. Lub ntim nws tus kheej yog ib lub hnab plaub-txheej.

Lawv cov khoom yog masonry, tshav kub-resistant mixs, fireclay chips, cub av nplaum, thiab kuj kub-resistant.grout.
Txoj cai rau kev siv cov khoom sib xyaw "Terracotta"
Muaj ob peb txoj cai ua raws thaum siv cov khoom npaj ua los ntawm pawg no:
- Tom qab cov khoom tiav lawm twb khov lawm, kneading nws dua yog twb txwv.
- Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias "Terracotta" sib tov yog tsim los ntawm cov av nplaum kaolin, tsis tas siv cov cement, vim tias lub neej ntawm cov tshuaj tsis txwv. Thaum thickened, tsuas ntxiv dej thiab sib tov kom huv si.
- Tom qab tso lub qhov cub los ntawm cov khoom no yuav tsum tau ua ntawm qhov kub tsis qis dua 5 degrees.
- Pre-mixes siv ntau hom yas yas los tiv thaiv cov mortar kom qhuav sai heev. Ntawm qhov tod tes, qhov no tshem tawm qhov ua tiav ntawm qhov chaw tiav yuav pib tawg, thiab ntawm qhov tod tes, nws nce lub sij hawm xav tau rau ziab. Tsis tas li ntawd, nws tuaj yeem ua kom sov lub qhov cub uas siv Terracotta sib tov tsis pub dhau peb hnub tom qab tso tawm.
- Tseem muaj cov khoom sib xyaw ua ke rau kev teeb tsa chimneys. Lawv raug cim tshwj xeeb.
- Nws yog ib qho tseem ceeb uas yuav tsum paub tias txoj hlua hluav taws xob uas tsim los siv cov khoom sib xyaw ua ke tuaj yeem ua tiav 20-30 hnub tom qab nws pib siv tau zoo.
- Ib qho tsis yooj yim me ntsis yog tias tom qab thawj qhov hluav taws kub ntawm lub qhov cub, efflorescence yuav tshwm sim ntawm nws phab ntsa. Txawm li cas los xij, lawv tuaj yeem ntxuav tau yooj yim nrog daim ntaub ntub dej. Ntxuav lawv tom qab lub qhov cub txias lawm.
txiaj ntsig ntawm kev npaj sib tov
Cov tshuaj tiv thaiv tshav kub "Terracotta" yog cov tshuaj khib nyiab qhuav, uas yog npaj rau kev tso cov khoom uas yuav raug cua sov tom qab. Qhov kev daws teeb meem no yog tsim los ntawm kev siv tshuab hluav taws xob classical. Cov muaj pes tsawg leeg ntawm xws li ib tug sib tov muaj xws li kaolin av nplaum, qhuav thiab crushed, raws li zoo raws li fireclay (ceramic) chips. Qhov kub uas qhov sib tov no tuaj yeem tiv taus yog 1300 degrees Celsius. Nws yog ib qho tseem ceeb kom paub tias lub mortar tau txais lub zog tsuas yog thaum nws raug rho tawm haujlwm. Thiab qhov no txhais tau hais tias tom qab ua tiav tag nrho cov txheej txheem masonry, nws yuav tsum tau tos 48 teev. Tom qab lub sij hawm no, nws yog ib qhov tsim nyog los yaj lub cub tawg mus rau qhov kub ntawm 200-250C thiab tswj cov txheej txheem combustion nyob rau hauv lub xeev no mus txog 5-6 teev. Txhawm rau kom tsis txhob muaj qhov tsis yooj yim xws li tshem tawm cov sib tov tom qab masonry, cov kws tshaj lij pom zoo kom zoo nkauj plastering los yog hauv ob sab hauv lub qhov cub.
Clay-fireclay mix "Terracotta"
Qhov kev npaj sib xyaw no muaj cov khoom xyaw xws li kaolin av nplaum ntawm qhov siab tshaj plaws purity, xuab zeb, thiab kaolin chamotte. Zoo li lwm cov khoom sib xyaw, qhov no txawv ntawm qhov nws tuaj yeem tiv taus qhov kub txog +1300 degrees Celsius, thiab tseem yog ib puag ncig tus phooj ywg mortar qhuav.
Txhawm rau siv cov kev sib xyaw tshwj xeeb no, ob hom ntawm qhov chaw raug pom zoo, xws li ceramic lossis fireclay cib. Nyob rau hauv thiaj li yuav sib tov coj ib tug zoo zoo, nws yog tsim nyog los npaj lub hauv paus rau nws daim ntawv thov. Rau qhov no nws yuav tsumntxuav lub cib kom huv si los ntawm qhov ua tau ntawm cov xim qub, cov khib nyiab, av, plua plav, qub plaster thiab lwm yam. Tsis tas li ntawd, nws raug nquahu kom tuav lub cib hauv dej rau peb feeb ua ntej siv Terracotta masonry mortar.
