Cov neeg nyob hauv nroog nyob hauv cov tsev feem ntau tsis tshua xav tau xaim. Lub neej nyob deb nroog lossis kev tsim kho lub tsev (chaw tso tsheb ywj pheej) yog lwm qhov teeb meem. Thaum ntxiv dag zog rau lub hauv paus, yuav tsum tau xaim hluav taws xob.

Nws yog dab tsi?

Cov xaim hluav taws xob, lossis lwm yam knitting, yog qhov muag muag, nyias nyias. Kev muag muag tau los ntawm kev kho cua sov hu ua annealing. Yog li lub npe.

Thaum lub sijhawm ua kom sov, cov khoom ua haujlwm tau ua kom sov rau qhov ntsuas kub, khaws cia rau hauv lub xeev ua kom sov rau lub sijhawm tau teev tseg los ntawm thev naus laus zis, thiab tom qab ntawd maj mam txias . Cov tawv tawv tawm, thiab cov pas nrig nyias tau txais lub peev xwm los khoov ntau zaus yam tsis poob lub zog.

Yam ntxwv

Raws li GOST 3282-74, xaws xaim nrog ib puag ncig ntu ntu tau tsim . Txoj kab uas hla txawv hauv qhov me me. Cov khoom siv yog cov pa roj carbon tsawg.

Txhawm rau kom tau txais cov xov hlau nyias, cov khoom ua haujlwm tau rov ua dua ntawm cov tshuab nqus tsev. Nrog rau txhua daim ntawv qhia, xaim raug txo hauv txoj kab uas hla. Nyob rau tib lub sijhawm, nws nthuav dav raws nws qhov ntev.

Cov lus GOST tau hais qhia tias cov xaim mos, uas yog, nws tau kho cov cua sov.

Thaum lub sij hawm txhuam, sab hauv kev nyuaj siab tsim thaum lub sij hawm thinning raug tshem tawm ntawm cov hlau . Raws li qhov tshwm sim, cov qauv ntawm cov hlau bar dhau los ua cov nplua-zoo. Nws yog qhov tsim nyog tias nws yog qhov tshwj xeeb xws li cov qauv uas tshem tawm qhov txhaws thiab tiv thaiv kev tsim cov kab nrib pleb. Cov xov hlau muaj zog heev, nrog lub siab tawv thiab ductility.

Cov qauv ntawm kev xaiv

Muaj ob hom kev txhuam: lub teeb thiab tsaus. Thawj qhov tshwm sim nyob rau hauv lub tswb-hom rauv taws nyob rau hauv ib puag ncig roj inert. Cov khoom siv ua tiav yog lub teeb xim. Kev pleev xim dub yog ua thaum muaj cov pa oxygen. Dub xaim xaim xaim, raug rho tawm raws li hom thib ob, yog pheej yig dua li ib lub teeb.

Txoj kab uas hla ntawm cov khoom lag luam sib txawv ntawm 0.6 txog 6 hli. Cov khoom tiav yog dov rau hauv bays.

Galvanized xaim yog ruaj dua. Nws yog siv rau strapping cov qauv hlau ntawm cov hlua hauv paus.

Kev xaiv hom tshwj xeeb thiab txoj kab uas hla nyob ntawm:

• los ntawm kev tsim kho tshuab;
• kev ua haujlwm;
• txoj kab uas hla ntawm qhov cuab lub zog kom txuas nrog;
• nqi.

Cov xaim tau siv thaum txheej txheem txheej txheem tsis muab rau qhov muaj vuam . Hauv kev ua haujlwm nruj ntawm cov khoom, nws yog qhov zoo dua los siv ntau yam nrog cov polymer lossis txheej galvanized. Txoj kab uas hla ntawm txoj hlua khi uas yuav raug xaiv yog nyob ntawm txoj kab uas hla ntawm qhov cuab lub zog. Piv txwv, rau kev txhawb nqa nrog D = 8, 0-12, 0 mm, xaim nrog D = 1, 2-1, 4 mm xav tau.

Feem ntau nws tau lees paub tias ib pawg hlua ntawm ob kaum-millimeter rods xav tau txog 25 cm ntawm cov ntaub ntawv uas tau muab pov tseg. Yuav tsum tau ib daim 50 cm rau ib lub pob uas muaj peb txoj hlua.

Muaj cov ntxhuav rau kev hloov pauv hnyav ntawm xaim mus rau meters. Yog li, hauv 1 kg nrog txoj kab uas hla:

• 1 hli ntev yog sib npaug rau 162 m;
• 1.2 hli - 112.6 m;
• 1.4 hli - 82.6 m;
• 1.6 hli - 65.4 m;
• 1.8 hli - 50.0 m;
• 2.0 hli - 40.5 m.

Tus nqi ntawm cov khoom yog nyob ntawm txoj kev ua. Dub yog qhov pheej yig tshaj, galvanized yog kim dua.

Scope ntawm daim ntawv thov

Cov xaim xaim xaim yog xav tau los ntawm cov tuam ntxhab ntawm cov khoom siv ua vaj tsev.

Nrog nws pab:

• kev txhawb zog yog khi rau hauv tus ncej khov kho;
• fasteners tau ruaj khov kho ua ntej vuam.

Cov xaim mos tau siv rau kev tsim khoom:

• saw-txuas mesh;
• masonry nets;
• hlau hlua;
• barbed hlau.

Nws yog qhov xav tau thaum thauj ntau yam khoom. Qee qhov xwm txheej, ib feem ntawm ib tus neeg tau txuas nrog xaim hauv pob khoom, coils thiab rolls, hauv lwm qhov nws tau siv los tiv thaiv cov thawv thiab ntim khoom.

Cov yeeb yaj kiab nyias nyias tau siv hauv cov khoom siv hluav taws xob, hauv tsev, ntawm cov chaw tsim kho thiab hauv kev cob qhia tsim khoom.

Lawv kuj tseem xav tau:

• thaum txhim kho laj kab;
• tsim cov ntawv clips, ruffs;
• tying cav;
• kev tsim khoom ntawm txhua yam ntawm cov qauv me me, piv txwv li, wreaths;
• kho cov phiaj thiab hauv ntau qhov xwm txheej.
