Cov pa cua yas tau tshwm sim ua haujlwm tsis ntev dhau los. Cov khoom no yog yas thiab pheej yig. Lawv tuaj yeem hloov cov qauv hlau zoo. Tsis tas li ntawd, lawv muaj ntau qhov zoo ntawm lawv. Yas cua ducts yog ib qho yooj yim rau siv thiab nruab. Lawv muaj lub zog txaus nrog lub zog sib dua. Thiab yog, lawv kuj pheej yig dua. Tsis tas li ntawd, lawv tiv taus corrosion, lawv tuaj yeem ntsia tau rau hauv ib chav nrog cov av noo siab. Resistant rau acids thiab alkalis, uas tso cai rau lawv siv nyob rau hauv electroplating khw, tshuaj nroj tsuag, tshuaj thiab zaub mov industries. Lub tshuab cua yas tsis tso tawm cov khoom tsis zoo thiab tsis muaj kev phom sij rau tib neeg kev noj qab haus huv. Nws feem ntau yog siv los ua qhov cua hauv cov tsev nrog coob tus neeg. Yas cua ducts ua rau cua tshuab ntsiag to thiab siv zog vim lawv qhov chaw du. Txhawm rau tiv thaiv cov plua plav los ntawm kev sib sau ntawm lawv, lawv tau kho nrog cov tshuaj tiv thaiv kab mob. Thiab kev thauj mus los ntawm cov qauv zoo li no yooj yim dua. Tab sis cov pa ducts no muaj lawv qhov tsis zoo. Thiab, tej zaum, qhov tseem ceeb yog qhov flammability ntawm yas.

Yas duab plaub cua ducts tshwj xeeb tshaj yog siv nyob rau hauv kev lag luam thiab thaj chaw nyob. Lawv yooj yim rau nruab raws li lawv cov duab ua rau lawv yooj yim rau nruab rau hauv qab nthab thiab phab ntsa lossis so ntawm lwm qhov chaw. Lawv yog qhov tshwj xeeb tshaj yog qhov tseem ceeb rau kev txhim kho hauv cov xwm txheej nyuaj lossis thaum qhov chaw hla ntu loj dhau. Cov qauv ntawm daim ntawv no yog tshwj xeeb tshaj yog yooj yim thaum lawv mounted nyob rau hauv suspended ceilings. Muaj cov ducts zoo li no, uas qhov siab yog plaub zaug tsawg dua qhov dav. Cov qauv zoo li no hu ua tiaj. Lawv sib sau ua ke ntawm tes. Lawv qhov tsis zoo yog tias lawv suav tias tsis muaj suab nrov thiab tiv taus huab cua ntau dua. Cov qauv tsim no qee zaum xav tau kev yuav khoom siv ntxiv (xws li kiv cua, silencers).

Polypropylene qhov cua

Kev tso cua kom zoo hauv tsev yog ib qho tseem ceeb rau kev nyob zoo. Lub cev tsis zoo yuav ua rau nws tus kheej sai sai los ntawm cov av noo, tsw, thiab kov cov roj hauv chav ua noj. Hauv thaj chaw nyob, qhov cua tshuab ua los ntawm cov yas cua ducts yuav zoo heev. Rau cov hom phiaj no, polyethylene, polypropylene, polyurethane, PVC, silicone thiab lwm yam khoom siv hluavtaws yog siv. Qhov cuaCov txheej txheem ua los ntawm polypropylene yog cov dej tsis muaj dej, hnav-tiv taus, tiv taus cov tshuaj lom neeg ib puag ncig, rau ultraviolet hluav taws xob. Lawv muaj lub neej ua haujlwm ntawm 50 xyoo. Ua haujlwm kub ntawm -40 txog +85 ° C. Tab sis rau chav ua noj, PVC ducts yog zoo dua. PVC yog cov khoom siv ntau yam thiab muaj cov khoom zoo tshaj plaws ntawm cov yas. Nws txawv ntawm lwm cov ntaub ntawv los ntawm kev ua haujlwm ntev - txog li 100 xyoo, thiab kev nyiam huv siab.
