Cov khoom siv hauv tsev niaj hnub ua lag luam tau hloov kho tas li nrog ntau yam khoom tshiab, uas, vim lawv cov yam ntxwv thiab cov khoom zoo, tau pib muaj kev xav tau ntawm cov neeg siv khoom. Cov kev hloov tshiab no suav nrog gypsum fiber, lossis gypsum fiber ntau.
GVLV yog dab tsi?
Moisture-resistant gypsum fiber yog cov khoom tiav hauv daim ntawv ntawm daim duab plaub thiab ua los ntawm gypsum thiab xoob cellulose rau kev txhawb nqa, nrog rau ntau yam kev siv ntxiv. Nyob rau hauv tsos thiab qauv, cov khoom no zoo ib yam li cov phab ntsa ntub dej, tab sis muaj ntau yam zoo. Peb yuav qhia rau koj paub ntau ntxiv tias daim ntawv gypsum fiber ntau yog dab tsi. Ua ntej koj yuav tsum to taub dab tsi xoob pulp yog. Qhov no fiber ntau yog ruaj khov heev. Nws yog qhov zoo no uas tau siv dav hauv kev tsim cov khoom siv hauv tsev. Nrog kev pab los ntawm cov khoom tshwj xeeb, cog cellulose yog ua tiav nyob rau hauv ib txoj kev, ua tsaug rau lawv kom muaj ib tug uniform faib ntawm cellulose fiber ntau.tag nrho saum npoo. Los ntawm kev ntxiv cov tshuaj reagents rau qhov muaj pes tsawg leeg, vim li ntawd, cov khoom tiav tau txais uas muaj cov txiaj ntsig zoo ntxiv, xws li kev nyab xeeb hluav taws thiab kev tiv thaiv siab.
Scope of application
Cov dej resistant gypsum fiber ntau yog siv los ua kom tiav cov tsev nyob, kev lag luam, pej xeem, cov tsev ua haujlwm thiab thaj chaw. Cov khoom siv no, uas yog, GVLV, cov yam ntxwv ntawm cov txheej txheem uas yuav tau piav qhia hauv qab no, yog siv:
1. Rau sheathing attics, mansards, hauv qab daus. Hauv cov xwm txheej no, lub tsev yuav tsum tau nruab nrog lub qhov cua.
2. Rau kev npaj ib tug qhuav screed. Kev txhim kho cov dej-resistant gypsum fiber ntau yog lwm txoj hauv kev siv lub sijhawm ntawm kev ua cov cement screed nrog cov classic version, tab sis cov qauv no siv sij hawm tsawg dua thiab nyuaj.
3. Rau kev ua tiav chav dej, chav ua noj, chav hnav khaub ncaws, chav siv hluav taws xob. Txij li thaum nyob rau hauv cov chaw no muaj qhov tsis ruaj khov thiab feem ntau cov av noo siab, nws yog qhov tsim nyog yuav tsum siv daim ntawv gypsum-fiber (moisture resistant) ua tiav. Txhawm rau tiv thaiv cov nplooj ntawv los ntawm qhov tsis zoo ntawm cov kua dej, lawv qhov chaw yog kho nrog cov tshuaj hydrophobic, thiab cov khoom siv tsis zoo tuaj yeem siv los ua cov khoom zoo nkauj.
4. Rau npog ceilings thiab phab ntsa ntawm garages thiab outbuildings, rau unheated thaj chaw uas muaj ib tug muaj peev xwm ntawm khov ntawm phab ntsa.
5. Rau kev kho vaj tse thiab kev tsim kho thawj zaug ntawm gyms, tsev hais plaub thiab kev cob qhiathaj chaw, cov me nyuam chav ua si. Vim muaj cov cuab yeej xws li lub zog, cov ntawv gypsum fiber ntau muaj peev xwm tiv taus cov ntsiab lus siab, khaws nws qhov zoo li qub thaum ntaus los ntawm cov khoom hnyav, xws li cov khoom siv kis las.
6. Rau kev ua tiav of the elevator shafts (tus neeg caij tsheb thiab cov khoom thauj), rau hauv ob sab hauv chav boiler thiab chav vaj huam sib luag. Thaum hluav taws kub, cov khoom tiav tsis tawg rau lub sijhawm ntev thiab txwv kev sib kis ntawm nplaim taws.
GVLV: specifications
Cov dej resistant gypsum fiber ntau muaj cov hauv qab no kev zoo:
- qib siab ntawm kev phooj ywg ib puag ncig;
- kev ua tau zoo ntawm cov cua sov thiab lub suab rwb thaiv tsev;
- tiv thaiv hluav taws (GVLV tsis ignite);
- lub zog siab thiab hnav tsis kam, muaj peev xwm siv nws hauv cov tsev nrog kev teeb tsa nyuaj;
- yooj yim ntawm kev teeb tsa, kev siv gypsum fiber ntau txo cov nqi zog thiab sijhawm siv;
- GVLV, cov yam ntxwv ntawm qhov peb tab tom kawm tam sim no, yog cov khoom siv tau yooj yim, thiab qhov no ua rau nws muaj peev xwm nthuav dav ntau yam ntawm nws daim ntawv thov;
- txaus siab txaus ntawm hygroscopicity ntawm cov khoom, uas muaj peev xwm tswj cov av noo nyob rau hauv chav tsev, uas yog, nrog ib tug tshaj ntawm noo noo, nws absorbs nws, nrog ib tug tsis muaj ntawm nws, nws tso tawm;
- txo qis ntawm cov pov tseg (muab tias kev suav ua ntej ntawm cov khoom siv hauv tsev tau ua tiav), uas txuag cov nqi.
Qhov tseem ceeb ntawm gypsum fiber ntau
Hauv kev tsim cov gypsum fiber ntau, qhov ntev ntawm daim ntawv (nws qhov dav) nyob ntawm lub hom phiaj ntawm daim ntawv thov. Yeej, GVLV yog tsim nrog lub thickness ntawm 10 mus rau 12 hli. Qhov loj ntawm cov khoom tiav yog 2500x1200 mm. Nyob ntawm qhov tuab, qhov hnyav ntawm GVLV yog li ntawm 39 txog 42 kg. Qhov ntau thiab tsawg yog universal thiab haum rau yuav luag txhua hom kev ua tiav thiab kev tsim kho. Ntxiv rau qhov ntau thiab tsawg, cov ntawv phab ntsa yog 14, 16, 19 mm tuab. Qhov ntev ntawm daim ntawv tuaj yeem yog 2000, 2700, 3000, 3600mm thiab qhov dav yog 600mm.
Cov ntawv yog tsim nyob rau hauv ob hom:
- nrog seam ntug (rau phab ntsa, qab nthab);
- nrog txoj kab ncaj nraim (rau hauv pem teb).
Xaiv cov dej noo tiv thaiv gypsum boards
Thaum xaiv gypsum fiber ntau ua cov khoom tiav, ua ntej ntawm tag nrho cov, koj yuav tsum xyuam xim rau cov chaw tsim khoom. Ntau tus pom zoo kom yuav cov dej-resistant GVLV los ntawm cov tuam txhab hauv tsev, yog li txuag nyiaj txiag. Thaum muas cov khoom siv hauv tsev no, koj yuav tsum tau them sai sai rau qhov muaj cov cim thiab daim ntawv pov thawj ntawm kev sib haum xeeb. Tom ntej no, koj yuav tsum visually soj ntsuam cov nplooj ntawv - lawv nto yuav tsum du, tsis pom kev puas tsuaj. Tsis tas li ntawd, bulges, chips, tawg thiab ntau yam kev nyuaj siab tsis raug tso cai. Yog tias ua tau, nws yuav tsum tau txiav txim siab raws li cov xwm txheej twg cov khoom tau khaws cia. Yog tias cov nplooj ntawv nyob hauv chav nrog cov av noo siab, tom qab ntawd qhov no yuav cuam tshuam rau nws cov khoom.
Gypsum fiber ntau pem teb board
GVLV yog siv los tso rau ntawm ob qho tib si ntoo thiab pob zeb pob zeb. Nyob rau hauv lub xub ntiag ntawm qhov cua zoo, nws yog mounted rau ib tug qhob screed. Rau kev ua haujlwm nws raug pom zoo kom siv cov phaj me me - 12 hli tuab. Kev teeb tsa yog ua raws li hauv qab no:
1. Ib daim kab xev nplaum txuas nyob ib ncig ntawm chav tsev, ib txheej ntawm cov yas zaj duab xis tau muab tso rau.
2. Poob pw tsaug zog nthuav av nplaum los yog muab ib tug ntom rwb thaiv tsev. Nws yog compacted thiab leveled.
3. Lawv pib nteg gypsum fiber ntau GVLV ntawm kaum.
4. Thawj txheej ntawm daim hlau yog them nrog PVA kua nplaum los yog mastic. Tom ntej no, txheej thib ob ntawm gypsum fiber yog pw.
5. Nrog kev pab los ntawm screws, cov khaubncaws sab nraud povtseg yog rub ua ke.
6. Thaum kawg, hauv pem teb saum npoo yog primed, ces ib txheej txheej yog mounted, piv txwv li, linoleum.
Txawm hais tias GVLV cov yam ntxwv kev ua haujlwm siab heev, qhov chaw ntawm cov khoom siv no yuav tsum tau ua tib zoo ua tiav:
1. Cov nplooj ntawv gypsum fiber ntau yuav tsum tau primed ua ntej siv cov tsho loj.
2. Qhov saum npoo sheathed nrog gypsum fiber, uas nws tau npaj los ua cov nplaum nplaum, yuav tsum tau kho nrog methylcellulose-raws li kua nplaum.
3. Nws raug tso cai siv cov xim: dispersion los ntawm cov khoom siv dag zog, roj, kua roj vanish, epoxy thiab lwm yam.
4. Cov txheej txheem gypsum plasters nrog cov khoom siv dag zog tuaj yeem siv tau.
5. Nws yog undesirable mus yuav cov xim raws li kua iav, silicates, txiv qaub, thiabkuj alkaline.
Summing, peb tuaj yeem xaus tias GVLV gypsum fiber ntau yog ib theem tshiab hauv kev tsim cov khoom siv hauv tsev. Nws tsis muaj qhov tsis zoo uas muaj nyob hauv phab ntsa ntub dej. Thaum lub sij hawm tsim cov gypsum fiber ntau, ib tug xov tooj ntawm kev txhim kho tau ua kom zoo dua cov khoom ntawm cov khoom.
