Nyob hauv cheeb tsam suburban, uas nyob deb ntawm lub nroog txwv, yuav tsum muaj cov kav dej phwj tuaj. Nws tuaj yeem tsim tsis tau tsuas yog ua kom tau raws li cov kev xav tau ntawm tsev neeg, tab sis kuj ua lwm yam haujlwm.
Ntau yam dej phwj
Hnub no muaj ob peb hom kev lim dej:
- stock;
- nag xob nag cua;
- kho dej thiab lwm yam.
Cov dej phwj kuj tseem muab faib ua:
- internal;
- external.
Txoj kab uas hla ntawm cov kav dej phwj thiab lawv cov kev xaiv nyob ntawm qhov tseeb ntawm cov yam ntxwv no.
ntau yam kav
Txhawm rau ua kom cov kav dej hauv thaj tsam suburban, koj yuav tsum xub txiav txim siab txog kev xaiv cov kav dej rau nws. Muaj ntau ntau yam:
- plastic;
- metal;
- ceramic;
- cam khwb cia hlau.
Txhua yam ntawm cov tsiaj no muaj nws tus kheej tshwj xeeb thiab cov khoom. Lawv cov kev faib thiab kev siv kuj txawv. Txoj kab uas hla ntawm cov kav dej phwj tuaj ntawm txhua hom kuj txawv, tab sis hauv qee qhov kev hloov kho khoom nws yuav zoo ib yam. Lawv nto kuj yuav txawv:
- smooth;
- corrugated.
yam ntxwv ntawm cov kav dej yas
cov kav dej yas yog tsim los ntawm ntau yam ntaub ntawv:
- polyvinyl chloride;
- Ypolypropylene;
- Ypolyethylene.
Polyethylene kav yog tsim los ntawm cov khoom siv raw nrog cov qauv ntom ntom. Lawv tuaj yeem siv rau sab nraud thiab sab hauv dej phwj tuaj.
Qhov zoo ntawm cov kav dej yas
Tam sim no, hom yeeb nkab no siv rau kev tsim cov kav dej ntau dua. Qhov nrov ntawm cov khoom no yog vim tsis yog rau cov nqi qis xwb, tab sis kuj yog cov khoom zoo thiab cov yam ntxwv.
Plastic kav:
- tsis corrode;
- durable;
- reliable;
- durable;
- hnav resistant;
- frost-resistant;
- nplaim hluav taws;
- easy to install.
Qhov txiaj ntsig tseem ceeb ntawm cov kav dej yas yog tias lawv tsis xeb thiab tsis tuaj yeem cuam tshuam los ntawm huab cua thiab huab cua. Lawv tiv taus heev loads. Vim li no, lawv tuaj yeem tso rau hauv av ntawm qhov tob tob.
Qee zaum, cov kws tshaj lij pom zoo kom siv lub tes tsho thev naus laus zis thaum txhim kho cov kav dej yas rau hauv av. Nws suav nrog kev tso ib lub yeeb nkab rau hauv lwm qhov, uas loj dua hauv nws txoj kev.txoj kab uas hla. Los ntawm tib txoj cai, txhua cov yeeb nkab tuaj yeem raug insulated.
Mounting cov kav dej yas thiab txuas lawv ua ke yog qhov yooj yim heev. Rau qhov no, cov cuab yeej tshwj xeeb thiab fittings yog siv. Nws kuj tseem tsim nyog xav txog tias cov kab hauv qab ntawm PVC cov kav dej phwj yog txawv ntawm sab nrauv. Vim li no, nws tsim nyog xaiv fittings raws li qhov ntim sab nraud ntawm cov yeeb nkab.
Yog tias cov kav dej yas nkag mus tob rau hauv av, ces koj yuav tsum xub xyuas lawv kom pom qhov xau.
Lub neej ntev ntawm cov khoom zoo li no tau lees paub los ntawm cov qauv ntom ntom ntawm cov yas. Cov kav dej tsis hlawv thiab tsis raug rau qhov kub thiab txias. Vim Frost, lawv yuav tsis deform, tab sis cov dej hauv lawv yuav khov. Vim li no, nws tsim nyog xav txog qhov rwb thaiv tsev ntawm cov kav dej phwj tuaj, uas nyob saum cov av khov.
Txoj kab uas hla ntawm cov kav dej PVC yog xaiv raws li hom kev lim dej uas tau tsim nyob rau hauv cheeb tsam suburban. Yog tias cov no yog cov dej ntws yooj yim, ces koj tuaj yeem xaiv ib qho me me. Yog tias nws yog cua daj cua dub lim dej, ces txoj kab uas hla ntawm cov yeeb nkab yuav tsum yog qhov tseem ceeb kom tsis txhob ncua kev hla dej.
kab ntawm cov khoom yas
Txoj kab uas hla ntawm cov kav dej phwj yas muaj ntau yam. Lawv xaiv nyob ntawm seb hom dej phwj tuaj yeem yog sab nraud thiab sab hauv.
Rau qhov kev npaj ntawm cov kav dej hauv tsev, cov kav dej uas muaj txoj kab uas hla ntawm 32 txog 110 hli yog siv. Rau sab nraud, cov kav dej yog siv, txoj kab uas hla yog 110 thiab 160 mm.
rau sab nraudCov kav dej phwj yog qhov zoo tshaj plaws rau cov kav dej phwj yas. 110 yog txoj kab uas hla yuav yog qhov kev xaiv zoo tshaj plaws.
yam ntxwv ntawm cov kav dej kav hlau
Hom no tsis yog siv los npaj cov dej khib nyiab. Qhov no yog vim lub fact tias cov hlau yuav raug corrosion, tshwj xeeb tshaj yog nyob rau hauv cov av. Tsis tas li ntawd, cov quav hniav yuav tsim nyob rau hauv cov yeeb nkab thaum lub sij hawm, uas txo nws txoj kab uas hla thiab yog li ua rau nws nyuaj dhau.
Raws li lawv cov yam ntxwv, cov kav hlau:
- durable;
- resistant rau ib qho kev thauj khoom.
Tib lub sijhawm, lawv sov thiab khov zoo kawg nkaus.
Ceramic kav hauv kev tsim cov kav dej
Cov kav dej phwj no yog siv los tsim cov kav dej tawm sab nraud. Txoj kab uas hla ntawm cov kav dej ceramic tuaj yeem yog 150 txog 600 hli.
khoom specifications:
- av resistant;
- frost resistance;
- hluav taws kub;
- practicality;
- durability;
- zog;
- reliability.
Lub hauv paus ntsiab lus ntawm lawv qhov kev teeb tsa thiab kev sib txuas ua ke zoo ib yam li kev teeb tsa thiab kev sib txuas ntawm cov kav hlau cam khwb cia.
cam khwb cia hlau kav dej
cam khwb cia hlau yog cov khoom siv los ua cov kav dej thiab cov kav dej rau ntau xyoo. Nws tau tswj kom ua pov thawj nws tus kheej hauv kev tsim cov khoom no ua cov khoom siv zoo tshaj plaws thiab txhim khu kev qha. Cam khwb cia hlaucov kav dej tuaj yeem siv los npaj txhua hom kev lim dej. Nov yog lawv lub ntsiab kom zoo dua.
Specifications of cam khwb cia hlau kav
Txawm hais tias hom khoom no tsis siv ntau zaus hauv kev tsim kho cov kav dej, cov kav hlau cam muaj lawv tus yam ntxwv. Cov no suav nrog:
- corrosion resistance;
- hluav taws kub;
- frost resistance;
- hnav resistant;
- zog;
- kev pabcuam lub neej.
Nws tseem tsim nyog xav txog tias txoj kab uas hla ntawm cov kav dej cam khwb cia hlau tuaj yeem yog ib qho. Nws yog siv rau kev tsim kho ntawm ob sab hauv thiab sab nraud cov dej phwj tuaj. Lub neej kev pab cuam ntawm cov kav hlau cam yog tsawg kawg yog 80 xyoo.
Ntau zaus, cov kav dej cam khwb cia hlau txoj kab uas hla ntawm 150 lossis 200 hli raug xaiv rau cov kav dej hauv tsev ntiag tug.
Ntxiv rau qhov zoo paub zoo, muaj ib qho tsis zoo. Qhov saum npoo ntawm cov qauv no, ob qho tib si sab nraud thiab sab hauv, yog ntxhib. Sij hawm dhau mus, nws tuaj yeem ua rau txhaws txhaws.
Tsis tshua nrov cov kav dej
Ntxiv rau hom qauv, muaj lwm yam uas tseem tsis tau muaj kev nyiam siv, tab sis kuj muaj cov khoom siv zoo.
Cov no suav nrog cov kav dej:
- reinforced concrete:
- fiberglass;
- asbestos-cement.
Cov pob zeb muaj zog feem ntau yog siv los npaj cov kav dej hauv nruab nrab. Txawm hais tias cov xwm txheej ntawm lawv siv nyob rau thaj tsam suburban hauv nruab nrabib lub yeeb nkab uas txuas ob peb lub kav dej. Lawv muaj zog thiab txhim khu kev qha. Txawm li cas los xij, lawv muaj peev xwm ua kom tawg dhau lub sijhawm nyob rau hauv kev cuam tshuam ntawm qhov chaw ntub dej. Tsis tas li ntawd, cov kav dej txuas ntxiv muaj qhov loj, uas ua rau lawv nyuaj heev rau kev teeb tsa los ntawm tes.
Txhim kho cov kav dej phwj nrog txoj kab uas hla ntawm 100 hli thiab hnyav txog 50-60 kg. Vim li no, nws lub installation yog nqa tawm nrog cov cuab yeej tshwj xeeb.
Fiberglass kav kuj tsis nrov heev. Lawv tsis muaj zog heev, tab sis tib lub sijhawm lawv tsis tuaj yeem raug cov dej noo. Lawv kuj tuaj yeem siv rau hauv kev tsim kho cov kav dej sab hauv thiab sab nraud, tab sis koj yuav tsum tsis txhob muab tso rau hauv av.
