Nyob rau hauv thaum pib yog li ntxhuab

Moss nrog ntev fibers (liab ntxhuab, sphagnum ntxhuab Kukushkin flax) - ib txhis khoom rau thermal rwb thaiv tsev ntawm cav tsev nyob rau hauv Russia. Nws zoo heev zoo - tsis muaj thermal conductivity, muaj peev xwm nqus thiab tso dej nyob rau cov av noo ntawm lub ambient cua, bactericidal zog - yog ib qhov nyuaj rau cov me nyuam nyob rau hauv cov khoom cua cov ntaub ntawv. Lub ntsiab drawback - qhov teeb meem uas muaj ntxawm ntawm lub koom haum thiab complexity nyob rau hauv installation.

Khoom raws li nyob rau hauv zaub fibers - mezhventsovogo zoo tshaj plaws rwb thaiv tsev. Tshwj xeeb tshaj yog thaum nws yog qhia tshwj xeeb uas npaj rau tso rau hauv ib lub cav los yog lumber. Flax, hemp (Cannabis fiber) tau ntev tau siv nyob rau hauv daim ntawv ntawm ib tug cab rau rwb thaiv tsev thiab caulking pob qij txha. Niaj hnub nimno manufacturers dhau lawv los ntawm lub carding tshuab thiab needled thiab muaj kev yooj yim rau siv lub sawb mob nyob rau hauv coils flax muaj thiab siv cab.

Nyob rau hauv daim ntawv no nkag mus rau cov kev siv kev ua lag luam thiab jute mezhventsovogo rwb thaiv tsev. Nyob rau hauv nws cov hauv paus - zaub raw cov ntaub ntawv muab rau Russia los ntawm lub teb chaws ntawm cov teb chaws Asia thiab teb chaws Africa.

Tsis yog txhua txhua lawm tab fibers yuav siv tau raws li rwb thaiv tsev rau mezhventsovogo ntoo los yog cav. Paj rwb los wool batting, muaj kiag li tsis haum rau lub hom phiaj no. Tsis tas li ntawd cov uas tsis muaj kev ceev, lawv xav nqus dej, thiab inevitably wool yog muab tso rau mol.

Mineral thiab hluavtaws

Nyob rau hauv niaj hnub siv kom insulate lub phab ntsa, Qab Nthab, plag tsev, ru tsev thov ib tug plurality ntawm cov ntaub ntawv nyob rau hauv daim ntawv ntawm cov mats, blocks, yob, tshuaj tsuag, thiab lwm yam Lawv muaj zoo heev zoo rau thermal kev tiv thaiv thiab dej kuj, tab sis nws tsis yog haum rau siv nyob rau hauv cov ntoo siv.

Lub ntsiab yog vim li cas - ib tug ua tiav mismatch yuav tsum rau vapor permeability. Tso cua sov rau lub hauv paus ntawm cov iav ntaub plaub thiab basalt mineral raw cov ntaub ntawv yog compressed nyob rau hauv lub ceeb thawj ntawm lub rims. Cov huab cua los ntawm qhov chaw ntawm lub fibers yog nias tawm thiab ntaub ntawv ib tug impermeable barrier rau pa dej muaj nyob rau hauv cov huab cua thiab nyob rau hauv cov ntoo xwb. Nyob rau hauv tas li ntawd mus rau lub deterioration ntawm lub vaj tse muaj kev nyab xeeb, tshaj noo noo condenses rau tus ciaj ciam ntawm cov ntoo thiab rwb thaiv tsev thiab maj txav lub array phab ntsa. Nyob rau hauv lub caij ntuj no, dej txuam nrog qhov chaw khov thiab cov txheej txheem ntawm cov yam ntxwv lub cev qhuav dej yog accelerating.

Tsis chaw dim pa thiab ntxeem tau polymeric cov ntaub ntawv. Polystyrene ua npuas ncauj, polyethylene ua npuas ncauj, nyuaj polyurethane ua npuas ncauj, ua npuas ncauj roj hmab, foams, adhesives, thiab ob peb ua ke ntawd yuav siv tsis tau raws li rwb thaiv tsev mezhventsovogo. Nyob rau hauv tas li ntawd mus rau lub sij hawm nyiaj, koj yuav tau txais lub tsev unfit rau lub neej thiab poob lub zog.

txawv qhua

Excluding flax thiab hemp muaj lwm yam zaub fiber. Nws yog nkag mus rau hauv tej chaw jute mezhventsovogo rwb thaiv tsev.

Cab yog zoo suited rau cov phab ntsa hauv cav los cav ntoo, npaj tsis muaj kev siv ntawm calibration machine. Rwb thaiv tsev sawb conveniently stacked on kab ntawm cav thiab Profiled laminated veneer lumber. Daim kab xev zoo txhim kho ib tug roj hmab, tus sawv tsis tau ntxiv caulking nqaws, nws yog yooj yim los mus ua lub mounting qhov rau lub pegs, thiab lwm yam

Lub physico-kev zoo jute fibers txhais pros thiab cons, uas yog manufactured therefrom mezhventsovogo rhaub. Jute muab nws ib tug ntom uas yog niaj hnub tshaj tag nrho ntev, ua hauj lwj, lub neej ntev. Ntau hygroscopic ntaub ntawv uas yuav ua tau ib tug disadvantage: ntev ya raws uas tau sau nyob rau hauv rwb thaiv tsev yuav ua tau kom khov ntawm cov phab ntsa. Tsis txaus ductility yuav ua nyob rau hauv lub tsim ntawm voids nyob rau hauv lub nqaws ntawm lub cav los yog bar.

Kwv yees li 2% ntawm qhov kev siv cov nqi ntawm lub tsev mus rau mezhventsovogo rwb thaiv tsev. Nqe ib 'meter' lnovatina band dav ntawm 20 cm nrog ib tug tuab ntawm 8-10 hom hli nyob rau nruab nrab 6 rubles. Ib tug zoo xws li cov rhaub ntawm 100% jute - 12 rubles. Jute - mas khoom, tus nqi ntawm nws cov siab domestic nyoos linseed.

Qhov zoo tshaj plaws kev xaiv
