Formulation thiab daim ntawv thov ntawm pobzeb adhesives

Pobzeb nplaum, tseem hu ua ceramic pobzeb nplaum, feem ntau yog siv los muab cov ntaub ntawv zoo nkauj xws li cov vuas luaj ceramic, cov nplais ntsej muag, thiab cov vuas hauv pem teb. Nws cov yam ntxwv tseem ceeb yog kev sib koom ua ke siab zog, dej tsis kam, khov-thaw kuj, zoo aging kuj thiab yooj yim siv. Nws yog cov khoom siv sib txuas zoo tshaj plaws. Pobzeb nplaum, tseem hu ua pobzeb nplaum lossis nplaum, viscose av nkos, thiab lwm yam, yog cov khoom siv tshiab rau kev kho kom zoo nkauj niaj hnub, hloov cov cement daj xuab zeb. Cov nplaum nplaum yog ob peb zaug ntawm cov cement mortar thiab tuaj yeem muab cov pob zeb loj loj, kom tsis txhob muaj kev pheej hmoo ntawm cov pob zeb poob. Zoo yooj yooj yim los tiv thaiv hollowing hauv ntau lawm.

qauv

Pobzeb nplaum muaj ntau yam additives, tshwj xeeb tshaj yog cov functionality ntawm pobzeb adhesives. Feem ntau, cellulose ethers uas muab cov dej tuav thiab cov nyhuv thickening yog ntxiv rau cov nplais nplaum, nrog rau cov hmoov latex uas ua rau kom cov nplaum nplaum nplaum nplaum. Cov hmoov latex feem ntau yog vinyl acetate / vinyl ester copolymer, vinyl laurate / ethylene / vinyl chloride Copolymer, acrylic thiab lwm yam additives, qhov sib ntxiv ntawm cov hmoov latex tuaj yeem ua rau kom yooj yim ntawm cov nplais nplaum thiab txhim kho cov nyhuv ntawm kev ntxhov siab, ua kom yooj.

Tsis tas li ntawd, qee cov pobzeb nplaum nrog cov kev ua haujlwm tshwj xeeb yog ntxiv nrog rau lwm cov khoom siv ntxiv, xws li ntxiv cov ntoo fiber ntau los txhim kho qhov kev sib tsoo thiab qhib lub sijhawm ntawm cov tshuaj khib nyiab, ntxiv cov hmoov txhuv nplej siab ether los txhim kho cov nplaum tiv thaiv ntawm cov mortar, thiab ntxiv zog thaum ntxov. cov neeg ua haujlwm ua kom cov pobzeb nplaum ntau dua. Ua kom muaj zog sai, ntxiv cov tshuaj tua kab mob kom txo tau cov dej nqus dej thiab muab cov nyhuv dej tsis zoo, thiab lwm yam.

Raws li hmoov: dej = 1: 0.25-0.3 ratio. Do sib npaug thiab pib tsim; nyob rau hauv lub sijhawm tso cai ntawm kev ua haujlwm, txoj haujlwm ntawm cov pobzeb tuaj yeem hloov kho. Tom qab cov nplaum tau qhuav tag (kwv yees li 24 teev tom qab ntawd, kev ua haujlwm caulking tuaj yeem ua tiav. Tsis pub dhau 24 teev ntawm kev tsim kho, cov khoom hnyav yuav tsum zam rau saum npoo ntawm cov pobzeb. ).

Kev sib koom ua ke siab, tsis tas yuav ntub cov cib thiab cov phab ntsa ntub dej thaum tsim kho, kev ua haujlwm zoo, tsis muaj dej, tsis muaj zog, tawg ua haujlwm, kev laus ua haujlwm zoo, kub tsis kam, khov-thaw kuj, tsis muaj tshuaj lom thiab ib puag ncig zoo, thiab kev tsim kho yooj yim.

03 Scope ntawm daim ntawv thov

Nws yog haum rau muab tshuaj txhuam ntawm sab hauv tsev thiab sab nraum zoov ceramic phab ntsa thiab pem teb vuas thiab ceramic mosaics, thiab nws kuj yog tsim rau cov waterproof txheej ntawm sab hauv thiab sab nrauv phab ntsa, pas dej ua ke, chav ua noj thiab chav dej, hauv qab daus, thiab lwm yam ntawm ntau lub tsev. Nws yog siv rau pasting ceramic vuas ntawm cov txheej txheem tiv thaiv sab nraud thermal rwb thaiv tsev. Nws yuav tsum tau tos rau cov khoom siv ntawm cov txheej txheem tiv thaiv kom kho tau rau qee lub zog. Lub hauv paus saum npoo yuav tsum qhuav, ruaj, tiaj tus, tsis muaj roj, plua plav, thiab tso tawm cov neeg ua haujlwm.

kho saum npoo

■ Txhua qhov chaw yuav tsum ruaj khov, qhuav, huv si, tsis muaj kev co, roj, siv quav ciab thiab lwm yam khoom xoob;

■ Cov pleev xim rau saum npoo yuav tsum tau roughened, nthuav tawm tsawg kawg yog 75% ntawm qhov qub nto;

■ Tom qab lub pob zeb ua tiav tiav lawm, nws yuav tsum tau kho rau rau lub lis piam ua ntej tso cib, thiab cov plastered tshiab yuav tsum tau kho tsawg kawg yog xya hnub ua ntej tso cib.

■ Cov pob zeb qub thiab plastered tuaj yeem ntxuav nrog xab npum thiab yaug nrog dej. Qhov saum npoo tuaj yeem tsuas yog pav nrog cib tom qab nws qhuav;

■ Cov khoom siv hauv paus yog xoob, dej-absorbing heev, los yog cov plua plav ntab thiab av ntawm qhov chaw yog qhov nyuaj los ntxuav. Koj tuaj yeem ua ntej siv Lebangshi primer los pab cov vuas daim ntawv cog lus.

05

Do kom sib tov

■ Muab TT hmoov rau hauv dej ntshiab thiab do rau hauv ib qho tshuaj txhuam, ua tib zoo ntxiv cov dej ua ntej thiab tom qab ntawd cov hmoov. Phau ntawv los yog hluav taws xob tov khoom siv tau rau kev sib xyaw;

Qhov sib tov yog 25 kg ntawm hmoov ntxiv rau 6-6.5 kg ntawm dej, thiab qhov ratio yog 25 kg ntawm hmoov ntxiv rau 6.5-7.5 kg ntawm additives;

■ stirring yuav tsum tau txaus, yuav tsis muaj mov ci. Tom qab stirring tas, nws yuav tsum tau nyob twj ywm rau li kaum feeb thiab ces stirred ib pliag ua ntej siv;

■ Cov mucilage yuav tsum tau siv li ntawm 2 teev raws li cov huab cua puag (lub crusted nto ntawm cov mucilage yuav tsum tau muab tshem tawm thiab tsis siv). Tsis txhob ntxiv dej rau cov kua nplaum qhuav ua ntej siv.

Kev tsim kho tshuab Toothed scraper

Siv cov kua nplaum rau ntawm qhov chaw ua haujlwm nrog cov hniav txhuam hniav kom nws sib npaug sib npaug thiab tsim ib txoj hlua ntawm cov hniav (kho lub kaum sab xis ntawm lub scraper thiab qhov chaw ua haujlwm kom tswj cov tuab ntawm cov kua nplaum). Siv li 1 square meter txhua lub sijhawm (nyob ntawm huab cua kub, qhov kev tsim kho kub yuav tsum yog 5-40 ° C), thiab tom qab ntawd knead thiab nias cov vuas ntawm cov vuas hauv 5-15 feeb (kho yuav siv sij hawm 20-25 feeb) Yog hais tias qhov loj ntawm cov hniav scraper raug xaiv, qhov flatness ntawm qhov chaw ua hauj lwm thiab cov degree ntawm convexity nyob rau sab nraum qab ntawm cov pobzeb yuav tsum tau txiav txim siab; Yog hais tias qhov zawj nyob rau sab nraum qab ntawm cov pobzeb yog qhov sib sib zog nqus los yog cov pob zeb thiab cov pobzeb loj dua thiab hnyav dua, cov kua nplaum yuav tsum tau siv rau ntawm ob sab, uas yog, Siv cov kua nplaum rau ntawm qhov chaw ua haujlwm thiab sab nraub qaum ntawm cov pobzeb tib lub sijhawm; ua tib zoo khaws cov pob qij txha expansion; Tom qab lub cib tso ua tiav, cov kauj ruam tom ntej ntawm kev sib koom ua ke yuav tsum tau tos kom txog thaum cov kua nplaum qhuav tag (li 24 teev); Ua ntej nws qhuav, siv Ntxuav cov nplais saum npoo (thiab cov cuab yeej) nrog ib daim ntaub ntub dej los yog daim txhuam cev. Yog tias nws kho tau ntev dua 24 teev, cov stains ntawm cov vuas luaj tuaj yeem raug ntxuav nrog cov pobzeb thiab pob zeb ntxuav (tsis txhob siv cov kua qaub ntxuav).

07

Cov kev ceev faj

1. Lub verticality thiab flatness ntawm lub substrate yuav tsum tau lees paub ua ntej daim ntawv thov.

2. Tsis txhob muab cov kua nplaum qhuav nrog dej ua ntej siv.

3. Ua tib zoo khaws cov pob qij txha expansion.

4. 24 teev tom qab paving tiav, koj tuaj yeem nkag mus rau hauv lossis sau cov pob qij txha.

5. Cov khoom no yog tsim rau siv nyob rau hauv ib puag ncig ntawm 5 ° C mus rau 40 ° C.

Kev tsim kho phab ntsa yuav tsum tau ntub dej (ntub rau sab nraud thiab qhuav rau sab hauv), thiab tswj kom muaj qee qhov kev tiaj tus. Qhov tsis sib xws lossis tsis tshua muaj qhov ntxhib yuav tsum tau ua kom zoo nrog cov cement mortar thiab lwm yam ntaub ntawv; lub hauv paus txheej yuav tsum tau ntxuav ntawm ntab tshauv, roj, thiab siv quav ciab kom tsis txhob cuam tshuam qhov adhesion; Tom qab cov vuas tau muab tso rau, lawv tuaj yeem txav thiab kho tsis pub dhau 5 mus rau 15 feeb. Cov nplaum uas tau nplawm tusyees yuav tsum tau siv kom sai li sai tau. Siv cov nplaum sib xyaw rau sab nraum qab ntawm cov cib pasted, thiab tom qab ntawd nias nyuaj kom txog thaum nws tiaj tus. Kev siv tiag tiag sib txawv nrog cov khoom sib txawv.
