Txhua tus neeg yuav muaj feem cuam tshuam nrog kev tso lossis hloov cov kav dej, yog li koj yuav tsum paub cov nuances ntawm lawv xaiv. Ntawm no peb yuav xav txog cov yam ntxwv tseem ceeb ntawm cov khoom lim dej - cov yeeb nkab ntau thiab tsawg, thiab tseem them nyiaj tshwj xeeb rau PVC ua cov khoom tsim.
Cov kav dej phwj yog tsim raws li TU 2248-022-23208482-02. Niaj hnub no cov kav dej phwj tuaj puv nrog cov khoom ntawm txhua qhov ntau thiab tsawg. Cov yam ntxwv tseem ceeb tshaj plaws yog txoj kab uas hla, qhov ntev thiab phab ntsa thickness.
Cia peb xav txog qee qhov ntau thiab tsawg ntawm cov yeeb nkab (piv txwv li txoj kab uas hla) rau cov kav dej.

Cov yeeb nkab thoob ntiaj teb muaj txoj kab uas hla ntawm 75 hli, nws lub hom phiaj yog txhawm rau tshem cov dej khib nyiab los ntawm cov khoom siv tsis huv (cov dab dej lossis cov dab da dej). Tab sis nws yog feem ntau yuav tsis haum rau lub tais tso quav, vim nws yuav tsis tiv taus xws li lub nra. Txhawm rau tshem tawm cov dej phwj tuaj ntawm chav dej, siv cov kav dej lim dej tsawg kawg yog 100-110 mm inch.
Txhawm rau thauj cov dej phwj tuaj ntawm chav dej, siv cov kav dej 90 hli inch. "Qhov twg siv cov yeeb nkab loj loj?" - koj nug. Yog, txhua yam yog yooj yim heev, lawv yog siv los mount risers thiab nteg cov kav dej phwj tuajdeb dhau tus qauv.
Thaum xaiv cov khoom lag luam los ntawm cov neeg lag luam, nco ntsoov tias cov khoom lag luam tubular muaj feem cuam tshuam, yog li koj yuav tsum tau qhia meej txog cov yam ntxwv xav tau. Rau cov khoom siv yeeb nkab nrog loj diameters, phab ntsa thickness yog tsim nyog. Piv txwv li, txoj kab uas hla ntawm 150-160 mm sib haum rau phab ntsa 3, 9, thiab ib txoj kab uas hla ntawm 110 mm sib haum rau 3 mm.
Tsis yog qhov hnyav xwb, tab sis kuj tseem siv cov khoom siv nyob ntawm qhov ntsuas kab. Yog li, ib lub meter khiav ntawm cov yeeb nkab nrog txoj kab uas hla ntawm 110 mm me ntsis dhau ntawm daim duab hauv kilograms, thaum lub yeeb nkab nrog txoj kab uas hla ntawm 160 mm twb hnyav dua - txog li ob kilograms.
Qhov tseem ceeb! Thaum hloov cov kav dej hauv vaj, cov khoom siv nrog txoj kab uas hla ntawm 300 hli yog siv.
YPVC yeeb nkab qhov ntev
Qhov tshwm sim ntawm polyvinyl chloride yog kev dhia hauv kev tsim kho tshuab. Tam sim no cov ntaub ntawv tab tom mus rau lub yeeb koob nrog leaps thiab ciam teb, tshem cov ntaub ntawv paub los ntawm lub neej txhua hnub. Cam khwb cia hlau, hlau thiab ceramics pib lag tom qab tus tshiab, ntau dua version. Tsis tas li ntawd, txhua qhov loj ntawm cov kav hlau steel tau tsim los ntawm cov khoom siv tshiab. Qhov zoo yog pom: tus nqi qis, kev pab lub neej ntev, lightness thiab ib puag ncig tus phooj ywg.
Nrog kev pab los ntawm cov cuab yeej siv niaj hnub no, nws tuaj yeem tsim cov kav dej sib txawv, suav nrog kev xav ntawm tus neeg yuav khoom. Xws li qhov zoo dua yuav xav tau rau kev ua haujlwm ntawm cov kws tshaj lij, thiab ib tus neeg zoo tib yam yuav tsis tuaj yeem nkag siab tag nrho cov no. Thaum saib daim ntawv lo thaum xaiv cov khoom siv, nws tsim nyog nco ntsoov tias tsuas yog qhov loj me yog qhia rau ntawd.sab nraud txoj kab uas hla, thiab nws cov nqi sab hauv yuav tsum tau txiav txim los ntawm kev rho tawm cov phab ntsa thickness. Qhov ntev ntawm cov kav dej polypropylene yuav tsum raug xaiv raws li lub luag haujlwm thiab thauj khoom rau lawv.
Qhov txiaj ntsig loj ntawm cov kav dej no yog qhov muaj peev xwm txiav tau yooj yim rau hauv daim nrog lub tshuab sib tsoo zoo tib yam. Ua tsaug rau qhov zoo no, kev teeb tsa feem ntau yooj yim thiab tsis tas yuav muaj kev txawj tshwj xeeb thiab kev paub dhau los.
