Nrog rau kev nthuav dav ntawm daim ntawv thov ntawm cov kav dej yas, cov hom ntawm cov kav dej yas kuj nce ntxiv. Tam sim no, ntxiv rau cov kav dej PVC thiab polyethylene zoo tib yam, kuj tseem muaj: PVC tub ntxhais ua npuas dej kav, PVC, PE ob-phab ntsa corrugated kav, aluminium-yas composite kav, Lian PE kav, yas steel puas kav, polyethylene silicon tub ntxhais kav, thiab lwm yam. .
Cov txheej txheem kev sib txuas ntawm cov kav dej yas muaj xws li: kev sib txuas ntawm cov neeg kho tshuab, kub yaj lub qhov (socket) vuam, kub yaj pob tw vuam, thiab qhov chaw vuam. Ntawm lawv, kub yaj pob tw vuam thiab qhov chaw fusion vuam yog cov kev sib txuas tseem ceeb rau cov kav dej yas.
Kub yaj welding tshuab welding
Thaum vuam, lub tshuab kub yaj vuam siv lub nplhaib sab hauv thiab sab nraud ntawm cov cuab yeej cua sov kom sov cov khoom sib txuas sab nraud thiab sab hauv lub nplhaib ntawm cov kav dej yas thiab cov khoom siv yuav tsum tau welded, ua rau lawv yaj. Cov cuab yeej cua sov yog rub tawm sai sai, thiab tom qab ntawd cov yeeb nkab tau nrawm nrawm rau cov yeeb nkab haum thiab siv qee qhov quab yuam kom ua tiav lub hom phiaj ntawm vuam tom qab txias. Feem ntau, kub yaj vuam yog tsim rau tej yaam num nrog diameters tsawg tshaj li 125 hli.
Kub yaj welding tshuab welding
Kub yaj welding tshuab taub qab vuam yog siv lub tshuab kub yaj lub taub qab vuam los ua kom sov lub vuam kawg ntawm ob lub kav dej (uas yuav tsum tau ntxuav los yog milled ua ntej vuam) rau qhov kub thiab txias, thaum lawv yaj, thiab tom qab ntawd sai sai haum lawv ua ke, thiab siv ib lub siab kom txog rau thaum txias ces ob lub kav dej yog welded ua ke.
Raws li txoj kev sib cuag ntawm lub phaj cua sov ntawm lub tshuab vuam thiab cov yeeb nkab yuav tsum tau welded, nws tuaj yeem muab faib ua ob txoj hauv kev: hu rau cua sov thiab hluav taws xob hluav taws xob infrared. Thaum welded raws li cov txheej txheem tsim nyog, lub zog tensile thiab lub zog-kev coj tus kheej ntawm Hankou cheeb tsam yog sib npaug los yog muaj zog tshaj cov yeeb nkab nws tus kheej. Kub yaj pob tw welding yog tsim rau welding yas kav nrog ib txoj kab uas hla ntau tshaj 90 hli. Nws yuav tsum tau muab sau tseg tias thaum lub sij hawm vuam txheej txheem, nws yog nruj me ntsis txwv tsis pub tiv thaiv sab nraud tej yam kev mob kom txog rau thaum nws yog tag nrho txias, thiab txhua txoj kev yuav siv tsis tau rau yuam txias.
Electrofusion vuam tshuab welding
Lub tshuab electrofusion vuam tshuab rau cov kav dej yas siv cov hluav taws xob cua sov nyob ntawm qhov chaw sab hauv thiab sab nrauv ntawm cov yeeb nkab electrofusion fittings los fuse rau sab hauv thiab sab nrauv ntawm cov yeeb nkab fittings thiab cov txheej txheem ntawm cov kav dej. Cov nyhuv thermal expansion ntawm cov yas welded kav nws tus kheej ua rau cov kav dej yas thiab lawv cov khoom sib txuas kom yaj. Blended ua ke thiab ces txias mus rau lub sij hawm yuav tsum tau mus cuag lub hom phiaj ntawm vuam.
Ua ntej vuam, qhov chaw vuam yuav tsum tau muab ntxuav los yog txhuam, feem ntau yog tshem tawm cov txheej txheej {{0}}.1 txog 0.3 hli oxide txheej. Kev tsim cov vuam tsis zoo yuav tsum raug xaiv raws li cov khoom siv raw, uas yog, lub sijhawm cua sov thiab qhov hluav taws xob cua sov lossis tam sim no yuav tsum tau tswj xyuas kom ntseeg tau tias qhov kub thiab txias ntawm cov yas molten ncav cuag qhov tsim nyog. , thiab tom qab ntawd tau txais cov khoom zoo yas welded pob qij txha.
