Xws li cov ntaub ntawv tsis raug raws li rub yog qhov tsim nyog rau siv hauv ntau lub lag luam rau lub hom phiaj tshwj xeeb: hauv kev tsim kho, cov kav dej, hauv kev tsim cov nkoj, thaum tso cov kav dej thiab cov hlua. Hauv tsab xov xwm no, peb yuav ua tib zoo saib cov yam ntxwv ntawm tus cab uas tsis tau rub thiab nrog cov hauv paus ntsiab lus uas siv rau cov khoom siv no.

Kev qhia tshwj xeeb

Tow yog cov khoom pov tseg tshwj xeeb los ntawm kev ua thawj ntawm flax, hemp thiab lwm yam qoob loo zoo sib xws. Nws zoo li tawv, ua kom tsis muaj fiber ntau. Nws muaj cov txiaj ntsig aseptic me ntsis thiab cov khoom zoo insulating . Hauv kev tsim kho kev lag luam nws tau siv los ua cushioning, ntim khoom, so cov khoom. Hauv kev lag luam kav dej, nws tau siv los ua kev ntseeg tau ntawm ntau yam kev sib txuas ntawm cov yeeb nkab sib txuas kom tsis txhob xau tau.

Oakum muaj cov khoom tseem ceeb hauv qab no:

• cov qauv uas tsis tau muaj lub neej ua haujlwm ntev tshaj plaws;
• vim yog kev nyab xeeb ib puag ncig, nws muaj peev xwm siv tau rau hauv txoj kab uas hla loj threaded sib txuas;
• tsis raug kev puas tsuaj los ntawm kab tsuag lom;
• yog cov khoom siv dag zog siab;
• muaj porosity zoo;
• muaj qhov nqus dej siab;
• tiv taus hnav;
• tsis suav nrog gluing cov yeeb nkab khoom rau ib leeg hauv cov chaw huv;
• muaj cov yam ntxwv antiseptic;
• tsis muaj peev xwm ua rau muaj kev tsis haum tshuaj rau tib neeg.

Hauv kev tsim khoom, cov khoom raug suav los ntawm 8 txog 24 units . Kev xaiv loj dua, qhov zoo dua ntawm cov khoom. Cov ntaub uas tsis muaj qhov tsis huv muaj xim beige. Cov cab zoo yuav tsum qhuav thiab tsis muaj ntxhiab tsw.

Resin tow yog cov khoom siv kab xev uas tsis tau pleev xim nrog cov roj-bitumen mastic, vim qhov kev txhim kho cov txheej txheem putrefactive tsis suav nrog. Nws yuav tsum tau tsim khoom raws li GOST 12285-77 (16183-77) ua raws li cov hauv qab no kev xav tau:

• cov khoom siv roj yog ua los ntawm daim kab xev ntawm qhov ntsuas qis ntawm cov xov paj luv ntawm flax, hemp, kenaf thiab kho nrog dej-tshuaj tua kab thiab tiv thaiv kab mob rotting;
• coj mus rau hauv tus account hom khoom siv raw thiab nws muaj pes tsawg leeg, cov khoom lag luam tau muab faib ua kev tsim nkoj thiab kev tsim kho.

Lub nkoj tsim qauv tau tsim los ntawm luv luv hemp, ua raws los ntawm impregnation nrog cob tawm los ntawm conifers. Qhov loj ntawm qhov hluav taws kub hauv cov khoom yuav tsum tsis pub ntau tshaj 10%.

Kev xaiv kev tsim kho tau tsim nyob hauv ob hom: thawj thiab thib ob

Tus qauv ntawm thawj hom yog tsim los ntawm cov xov luv luv ntawm flax thiab kenaf ntawm ntau yam tsis lossis lawv sib xyaw. Qhov hluav taws yuav tsum tsis pub tshaj 18% ntawm tag nrho qhov hnyav.

Tow ntawm qhov kev xaiv thib ob yog tau los ntawm kev sib xyaw ntawm cov paj rwb luv luv, kenaf thiab linseed bast ntawm cov lej sib txawv. Hauv qhov no, qhov hluav taws kub hauv cov khoom yuav tsum tsis pub ntau tshaj 24%. Thawj thiab thib ob cov khoom tau ua tiav nrog kho cov ntoo coniferous lossis cov hlua tshwj xeeb roj nplua nyeem ntawm qee hom:

• kom ua tiav qhov xav tau sib xws ntawm cov muaj pes tsawg leeg, tus qauv kerosene lossis lub cev muaj zog roj tau siv los ua qhov sib tov rau impregnation;
• qhov feem me me ntawm qhov tsis sib xws hauv cov khoom yuav tsum yog nyob ntawm thaj tsam 25% txog 35% ntawm tag nrho cov pawg;
• qhov ntom ntom ntawm cov kab xev ua tiav yuav tsum tsis pub tsawg dua 200 ktex;
• cov qauv uas tsis tau muab pov tseg yuav tsum tsis txhob tawg hauv nws qhov hnyav ntawm 1.5 meters hauv qhov ntev;
• ib feem impregnated yuav tsum tsis txhob lo rau ntawm cov phaj hlau thaum khov kho tawm tsam nws;
• thaum cov khoom tau khoov ntawm kaum ntawm 90 degrees hauv qhov txias 15-degree, qhov sib xyaw yuav tsum tsis txhob tawg thiab tawg tawm ntawm qhov saum npoo ntawm tus qauv.

Cov ntawv thov

Impregnated tow yog cov khoom pab tau zoo hauv kev tsim kho. Rau kev ua haujlwm zoo li no, kev xaiv bale feem ntau siv. Nws yog siv rau caulking nqaws, ntau yam kev sib koom ntawm cov khoom siv ua los ntawm cov hlau thiab ntoo. Yog li, vim tias qhov ua tau zoo ntawm qhov khoob ntawm cov yas, lub tsev yuav tsis ntsws. Nws kuj yog cov khoom siv zoo tshaj plaws rau kev sau voids nruab nrab ntawm lub qhov rais thiab qhov rooj thav duab thiab phab ntsa. Cov khoom lag luam tsis tuaj yeem siv ua ke nrog cov cement, gypsum thiab lwm yam kev daws teeb meem.

Hauv cov kav dej qhia, cov khoom siv no yog qhov tsim nyog rau kev sib khi pob qij txha thiab rau kev ua haujlwm kho cov dej, cua sov, thiab cov kav dej phwj tuaj . Hauv qhov no, impregnation yog roj bitumen, cob-bitumen mastics thiab tshwj xeeb ua rau cov tshuaj ua kom yaj.

Noj

Nyob ntawm thaj tsam ntawm daim ntawv thov, cov khoom tau muab faib ua ob txoj hauv kev:

• siv hauv thaj chaw kav dej;
• rau txheej txheem caulking.

Kev siv tag nrho cov khoom lag luam hauv cov haujlwm no tuaj yeem sib txawv heev, yog li cov khoom lag luam zoo sib txawv ntawm ib leeg hauv daim ntawv ntim khoom. Cov khoom lag luam caulking los hauv cov ntawv me me los yog pob. Txhawm rau suav kom raug tus nqi xav tau rau kev ua haujlwm tshwj xeeb, koj yuav tsum paub qhov hnyav ntawm tus cab hauv 1 m3.

Lub peev xwm Cubic tau xam raws li hauv qab no: qhov ntev, dav thiab qhov siab ntawm bale tau muab sib npaug

Txij li cov cab cab sib txawv kiag li, tom qab ntawd txoj hauv kev yuav tsum yog tus kheej.

Piv txwv li, cia peb nqa ib qho bale nrog cov hauv qab no:

• ntev - 0.45 m;
• dav - 0.5 m;
• qhov siab - 0.8 m;
• qhov hnyav - 10 kg.

Peb sib npaug: 0.45x0.5x0.8 = 0.18 m3

Yog li, peb pom tias hauv 10-kg bale nrog rau qhov ntsuas tsis pub dhau 0, 18 cubic meters. Nws yuav tsis nyuaj rau xam qhov hnyav ntawm 1 m3:

10: 0, 18 = 55, 6 kg

Cov kav dej xaiv yog hauv cov yob me me. Tus nqi ntawm kev rub yog nyob ntawm qhov kev daws teeb meem uas tau siv rau kev pub mis.

Yuav tsum khaws cov khoom li cas?

Txhawm rau tswj kom muaj txiaj ntsig zoo, cov khoom tiav yuav tsum tau muab cia rau hauv kaw, cov cua nkag tau zoo uas tsis muaj cua sov thiab ua tau raws li txhua qhov kev xav tau ntawm kev nyab xeeb hluav taws. Ib puag ncig yuav tsum ua tau raws li qhov yuav tsum tau ua. Cov dej tshwj xeeb yuav tsum muaj nyob rau hauv qhov xwm txheej ntawm cov dej ntws sib txawv . Txhawm rau kom muaj kev nyab xeeb ntxiv ntawm cov khoom lag luam los ntawm ntau yam tsis huv thiab noo noo, ib tus neeg ntim khoom yuav tsum tau siv.
