⑴ Nws muaj zog tensile zoo thiab compressive zog.

⑵ Tsis tshua muaj dej tsis kam:Phab ntsa ntawm UPVCcov kav dej yog du heev thiab tsis tshua muaj dej tsis kam. Nws roughness coefficient tsuas yog 0.009. Tsis tas li ntawd, lub peev xwm xa dej tuaj yeem nce ntxiv los ntawm 20% piv nrog cov kav hlau cam ntawm tib txoj kab uas hla thiab 40% piv nrog cov kav dej ua vaj tse.

⑶ Kev tiv thaiv corrosion zoo heev thiab tshuaj tiv thaiv: UPVC kav dej muaj cov kua qaub thiab alkali tsis kam thiab corrosion kuj. Lawv tsis cuam tshuam los ntawm noo noo thiab av PH, yog li tsis muaj kev kho corrosion yog xav tau thaum tso cov kav dej.

Cov dej zoo nruj: Kev teeb tsa ntawm UPVC kav muaj cov dej ua kom zoo tsis hais seb nws puas txuas los ntawm kev sib koom tes lossis roj hmab ib ncig.

⑸ Anti-tom: Vim tias cov kav dej UPVC tsis yog cov khoom noj khoom haus, lawv yuav tsis raug cov nas tsuag.

Cov chaw thov

PVC yas kavFeem ntau yog siv nyob rau hauv cov kav dej hauv tsev, kev tsim kho dej hauv nroog, cov kav dej cog cov kav dej thiab cov kav dej aquaculture. PVC yas kav kuj tseem siv tau los ua cov kav dej xa hluav taws xob rau cov xov hlau thiab cov kav dej kho mob. Tsis tas li ntawd, PVC cov kav dej yas kuj tseem siv tau rau hauv av los ua cov chaw nres nkoj roj av ntawm cov chaw siv hluav taws xob, xws li cov chaw nres nkoj hauv av, thiab tso cov kav dej hauv cov mines hauv av. Nws daim ntawv thov ntau yam yog dav heev.

Cov kav dej PVC me me yog siv los ua cov kav dej hauv tsev, cov kav dej nruab nrab tuaj yeem siv los ua cov kav dej hauv nroog hauv nroog, thiab cov kav dej loj tshaj plaws tuaj yeem siv los ua cov kav dej rau South-rau-North Water Diversion Project. Kuj tseem muaj cov yeeb nkab PVC me me uas tuaj yeem siv los ua cov kav dej xa hluav taws xob.

Yog tias cov yeeb nkab PVC ua tau sai sai tig daj, koj yuav tsum xyuas qhov teeb meem ntawm cov khoom siv PVC yeeb nkab.

1. Yog hais tias muaj teeb meem nrog lub thermocouple los yog kiv cua, nws yuav ua rau lub chim overheat hauv zos thiab ua rau cov khoom tig daj, uas yog, hlawv thiab tig daj. Kev daws: Xyuas seb cov thermocouples hauv txhua cheeb tsam ntawm lub thoob puas ua haujlwm zoo thiab seb cov kiv cua hauv txhua qhov chaw ua haujlwm li cas.

2. Yog tias cov roj hluav taws xob raug thaiv, qhov kev sib txhuam ntawm cov ntsia hlau tsis tuaj yeem raug tshem tawm zoo, uas yuav ua rau cov ntsia hlau overheat thiab ua rau cov khoom tawg thiab tig daj. Kev daws: Xyuas seb cov roj hloov hluav taws xob ntawm cov ntsia hlau puas txaus, seb cov roj twj puas ua haujlwm zoo, thiab seb cov roj yeeb nkab puas raug thaiv.

3. Nyob rau hauv cov ntaub ntawv ntawm cov ntsia hlau hnyav hnyav, qhov sib txawv ntawm cov ntsia hlau thiab lub thoob yuav loj dua, thiab cov ntsia hlau lub peev xwm los thawb cov khoom yuav tsis zoo, uas yuav ua rau cov khoom reflux nyob rau hauv lub thoob, kom cov khoom yuav rhuab. rau lub sij hawm ntev hauv lub thoob, ua rau yellowing. Kev daws: Koj tuaj yeem tshawb xyuas thiab kho qhov sib txawv ntawm cov ntsia hlau lossis hloov cov ntsia hlau.
