Yog li dab tsi yog xaim xaim? Nws tuaj yeem hais nrog qhov tseeb tias, tej zaum, yuav luag txhua tus neeg laus pom nws, tej zaum nws tsuas tsis paub tias nws yog nws. Yog tias, piv txwv li, koj saib lub ntsuas, uas yuav tsum muaj nyob hauv txhua lub tsev, tom qab ntawd koj tuaj yeem pom lub foob thiab xaim uas nws tuav - qhov no yog nws. Hauv kab lus no, peb yuav qhia koj txog nws kom ntxaws.

Yam ntxwv

Sealing hlau Nws yog cov khoom lag luam uas tau siv dav hauv ntau yam haujlwm, ob qho tib si hauv tsev neeg thiab kev tshaj lij. Feem ntau nws tau siv los ntawm cov tsev nyob thiab cov kev pabcuam hauv zej zog rau kev ntsuas lub ntsuas. Tsis tas li, cov khoom siv rau kev sib khi:

• qhov rooj uas nyob sab nraum zoov thiab sab hauv tsev;
• cov txee thiab kev nyab xeeb;
• txee, showcases, ntau lwm qhov chaw lag luam;
• tsheb thiab tsheb thauj khoom;
• cov tua hluav taws;
• terminals ntawm chaw nres tsheb ciav hlau;
• hnab ntim khoom;
• switchboards.

Txoj hlua khi yog tsim los tiv thaiv qhov qhib tsis tau tso cai thiab tawg ntawm cov khoom ntim lossis cov khoom ntim, nws kuj tsis tso cai rau lub foob kom raug yuam kom tshem tawm thiab tsis pub nws plam . Tias yog vim li cas nws yuav tsum ruaj khov thiab tsis txhob ntshai ntawm ntau yam kev cuam tshuam sab nraud - huab cua, kua qaub, thiab lwm yam.

Cov xaim hluav taws xob tau tsim tshwj xeeb raws li qhov yuav tsum tau ua ntawm kev cai lij choj kev coj ua, qhov tseem ceeb yog GOST 3282 - 74 "Cov pa roj carbon tsawg hlau rau siv dav. Cov txheej txheem ". Daim ntawv no piav qhia meej txog txhua qhov kev xav tau, khoom, uas cov khoom yuav tsum ua raws nrog. Tsis tas li, ntau qhov kev xav tau qhia, raws li qhov xaim yuav tsum:

• muaj kev tiv thaiv corrosion siab;
• yam ntxwv ntawm lub zog tensile siab;
• tiv taus ntau yam kev cuam tshuam ntawm cov tshuab.

Ua ntej nkag mus rau cov neeg siv khoom lag luam, cov khoom lag luam yuav tsum tau kuaj tus lej kuaj, tom qab ntawd cov txheej txheem kev ntsuas yuav tsum tau lees paub. Yog tias cov tshuab tsim khoom tau ua raws, cov hlau ua tau raws li qhov xav tau, cov khoom tau txais daim ntawv pov thawj zoo.

Hauv GOST 3282 - 74 kuj tau sau tawm cov cuab yeej tsim khoom ntawm cov khoom. Raws li cov ntaub ntawv tswj hwm no, cov khoom lag luam yuav tsum hla cov theem hauv qab no, cov txheej txheem tsim khoom.

1. Theem ntawm "etching". Cov hlau tsis xeb hlau tau tsau rau hauv cov tshuaj tshwj xeeb nrog cov ntsiab lus siab sulfuric acid. Cov txheej txheem no tshem tawm cov nplai txheej los ntawm cov khoom.
2. Tom ntej no, xaim raug ntxuav hauv cov dej ib txwm kom tshem cov sulfuric acid uas seem.
3. Npog cov hlau nrog txheej lubricating. Qhov kev tswj hwm no tso cai rau koj txhawm rau txhim kho cov khoom ntawm cov khoom ntawm thawj theem ntawm nws cov khoom.
4. Thaum kawg ntawm kev tsim khoom, cov cuab yeej tshwj xeeb tau siv, nrog kev pab uas txheej txheem ntawm ib lossis ntau daim duab ntawm cov xaim thiab nqa nws mus rau lub xeev xav tau tshwm sim. Cov txheej txheem kos duab ib leeg cuam tshuam nrog kev siv tsuas yog ib lub cuab yeej tshwj xeeb. Nrog cov duab rov ua dua, tus naj npawb ntawm cov fibers tso rau hauv chav tsev tuaj yeem ncav cuag 15 daim. Nrog kev siv ntau txoj kev rub, ib txoj kab uas hla me me tau ua los.

Tom qab ntawd, cov xaim hluav taws kub ntawm qhov kub ntau dua 900 ° C thiab txias hauv kev daws nitrate ntawm qhov kub ntawm 500 ° C. Rau kev tsim khoom, siv tshwj xeeb cov hlau qis lossis cov hlau tsis huv , uas tiv taus ib puag ncig txhoj puab heev thiab tuaj yeem tiv taus lub nra hnyav heev thaum ua haujlwm.

Saib

Cov khoom siv sib khi hlau niaj hnub no muaj ntau yam sib txawv. Cov khoom lag luam tuaj yeem sib txawv hauv cov thev naus laus zis tsim khoom, cov txheej txheem txheej txheem, cov khoom, xim, thaj tsam ntawm daim ntawv thov . Nws yog cais los ntawm xws li hom.

Twisted (xaws)

Rau nws cov khoom lag luam, siv cov hlau tsis huv, uas yog muaj peev xwm tiv taus cov khoom hnyav thaum lub sijhawm ua haujlwm thiab cuam tshuam tas li rau ib puag ncig txhoj puab heev . Hom khoom no nrov heev thiab feem ntau siv rau kev ntim khoom tseem ceeb. Twisted sealing hlau yog siv rau kev sib khi txhuas, yas thiab cov ntsaws ruaj ruaj.

Nws, nyeg, kuj tuaj yeem muaj ntau hom. Nws nyob ntawm cov khoom siv ntawm cov leeg tseem ceeb thiab theem ob ntawm cov khoom, uas yog:

• cov khoom yog ua los ntawm cov hlau tsis huv;
• galvanized hlau tau siv rau kev tsim cov hlau, nws lub hauv paus thiab qib thib ob;
• lub hauv paus yog ua los ntawm monofilament - kab nuv ntses, thiab tus neeg xyuas pib thib ob yog ua los ntawm cov hlau tsis huv;
• cov khoom ntawm cov khoom tau ua los ntawm galvanized monowire.

Cov xaim zoo li no yog siv rau kev sib khi cov laug cam, ntsuas cov cuab yeej, khoom siv hluav taws xob, cov ntsiab lus sib txuas lus, ntsuas.

Stainless

Yuav siv tau nrog cov lej, cov hlau lead lossis polyethylene ntsaws ruaj ruaj kom muab tej yam khoom pov tseg . Hom hlau no muaj ob lub cores - nruab nrab thiab theem nrab. Nws yog ua los ntawm cov ntaub ntawv zoo siv cov cuab yeej siv niaj hnub no. Tias yog vim li cas cov hlau hlau muaj cov cuab yeej siv siab, lub zog zoo thiab muaj kev sib haum xeeb siab ntawm kev ruaj ntseg.

Muaj cov txheej txheem hauv qab no:

• khoom kab - 0.5 hli, txhua tus cores nrog txoj kab uas hla 0.25 hli;
• muaj ob lub hauv paus;
• Kev puas tsuaj quab yuam coefficient - 9 kg.

Nws mus muag hauv daim ntawv ntawm cov kauj uas cov hlau nws tus kheej tau raug mob.

Tooj liab

Tooj liab - qhov no yog cov khoom siv uas feem ntau ua xaim. Thaum tsim cov khoom lag luam, cov ntaub ntawv txhim khu kev qha thiab niaj hnub no thiab cov cuab yeej siv tshiab tau siv. Raws li cov cuab yeej siv rau kev tsim khoom, cov tshuab tshwj xeeb tau siv - cov hlua hlau … Txoj kab uas hla ntawm tooj liab khi hlau yog los ntawm 038 mm txog 0.2 mm.

Txhuas

Aluminium tseem yog qhov khoom haum thiab siv ntau zaus. Cov txheej txheem tsim khoom zoo ib yam li kev tsim cov tooj liab hlau, cov hlau xaim kuj tseem koom nrog. Tab sis raws li qhov yuav tsum tau ua ntawm GOST, cov txheej txheem tsim khoom yuav tsum muaj ob theem.

• Thawj theem suav nrog cov txheej txheem kos duab tsis muaj zawv zawg. Tom qab cov txheej txheem no, txoj kab uas hla ntawm cov khoom yog los ntawm 0.45 mm txog 0.59 mm.
• Theem thib ob cuam tshuam nrog kev kos cov khoom, tsuas yog lub sijhawm no nrog zawv zawg. Tom qab cov txheej txheem no, qhov kawg ntawm qhov khoom, npaj rau kev siv, tau tsim, nws txawv ntawm 2.0 txog 0.3 hli.

Cov Lus Qhia Xaiv

Thaum xaiv cov xaim xaim, nws yuav tsum tau coj mus rau hauv tus account ob peb yam tseem ceeb, cov txheej txheem xaiv, ntawm qhov uas yog qhov tseem ceeb yog:

• hom khoom, saum toj no peb tau tham ntxaws txog txhua hom kev xaim hlau txuas;
• kev qhia tshwj xeeb;
• dab tsi raws nraim cov hlau xav tau rau kev sib khi;
• hom foob uas yuav muab ntsia rau ntawm cov hlau, cov khoom siv rau kev sib hloov thiab cov hlau lead sib txawv;
• nqe;
• chaw tsim khoom, nws yog qhov tseem ceeb los txiav txim siab tias lub tuam txhab twg yog tus tsim khoom ntawm cov khoom, nws yog qhov zoo tshaj los muab kev nyiam rau cov tuam txhab nto moo tshaj plaws, nrov thiab tsim tau zoo.

Tsis tas li, thaum yuav khoom, tsis txhob hnov qab nug txog qhov muaj daim ntawv pov thawj ntawm kev ua tau zoo thiab ua tau raws li cov khoom lag luam rau GOST.
