Ua ntej tso cov tawv hauv pem teb, hauv pem teb saum npoo yuav tsum tau ntxuav kom tshem tawm cov plua plav thiab cov khib nyiab kom tsis txhob cuam tshuam cov plua plav ntawm cov khoom sib txuas. Thaum muab tso rau hauv pem teb, tshuaj tsuag cov tawv tawv tshwj xeeb nplaum rau hauv pem teb thiab sab nraum qab ntawm cov tawv hauv pem teb tib lub sijhawm.Cov tawv thiab cov plywood pem teb yog tag nrho txuas, tsis muaj cua npuas raug tso cai, thiab kev sib txuas yuav tsum tau pastedIt' s zoo.
Vim lub complex thiab ntau yam duab ntawm lub hauv pem teb nto nyob rau hauv tag nrho lub tsheb, nws yog ib qho tseem ceeb uas yuav muaj teeb meem nyob rau hauv cov txheej txheem ntawm cov tawv thiab tawv ciam teb pob qij txha thaum lub sij hawm tso txheej txheem ntawm cov tawv hauv pem teb. Los yog kev yaig ntawm lwm yam, txhawm rau txhim kho lub zog ntawm hauv pem teb, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam cov pob qij txha ntawm cov tawv hauv pem teb kom zoo. Feem ntau muaj ob txoj hauv kev los tswj cov pob qij txha ntawm cov tawv hauv pem teb. Ib qho yog txuas nrog txhuas hlaws; lwm qhov yog siv cov cua kub welding. Cov seams ntawm pem teb tawv yog muab faib ua seams, txiv neej ces kaum seams thiab poj niam ces kaum seams. Txiv neej lub kaum pob qij txha tsuas yog kho nrog txhuas hlaws, thiab cov seams tiaj tus thiab poj niam lub kaum pob qij txha tuaj yeem txuas nrog txhuas hlaws thiab vuam.
Txoj kev sib txuas ntawm txhuas hlaws yog ib qho yooj yim rau kev khiav lag luam.Ua ntej, koj yuav tsum tau siv cov sealant waterproof rau cov pob qij txha kom tiv thaiv cov dej los ntawm kev nkag mus rau hauv qis txheej.Plywood, ua rau cov plywood rot. Tom qab ntawd siv tus kheej tapping screws los kho cov txhuas hlaws dai nws.
Kev ua haujlwm ntawm cov cua kub vuam yog qhov nyuaj. Pem teb tawv yog cov khoom sib xyaw nrog PVC ua cov khoom siv tseem ceeb, yog li nws cov vuam yog nyob rau hauv qeb ntawm cov yas vuam. Yas vuam tsuas yog siv cov cua kub welding. Thaum lub sij hawm vuam, lub tshuab hluav taws xob kub feem ntau yog siv los ua kom sov cov pob qij txha ntawm PVC pem teb tawv kom muag muag. Yas vuam muaj 4 lub ntsiab lus, uas yog kub cua kub, yas thiab qhov degree uas vuam hlau yog rhuab, vuam siab thiab vuam ceev. tshwj xeeb Cov txheej txheem yog raws li nram no.
1. Kev npaj ntawm lub interface. Lub seam yog txawv, thiab cov interface kuj txawv.Ua ntej vuam, ib tug tshwj xeeb grooving riam yuav tsum tau siv los txiav ib txoj kab nqes ntawm 60 ° rau lub tiaj tus weld. Qee lub sij hawm txhawm rau ua kom cov vuam du, nws tuaj yeem raug txo kom tsim nyog los ntawm 5 ° ~ 6 °, thiab qhov ntsuas siab yuav tsum ncaj. , Txoj kev ncaj yuav tsum tsis txhob siab tshaj 2 hli hauv 2m. Lub pob tw pob tw tuaj yeem siv ncaj qha rau poj niam fillet weld.
2. Tack vuam ntawm cov pob qij txha. Siv qhov tshwj xeeb qhov chaw vuam nozzle kom sov PVC pem teb tawv ntawm ib sab, thiab nias lub vuam seam ntawm qhov tod tes (zoo ib yam li hluav taws xob ferrochrome). Lub siab thiab cua sov tuaj yeem fuse ob sab ntawm PVC pem teb tawv. Lub hom phiaj ntawm qhov chaw yog ua kom cov PVC pem teb tawv routing kom raug, tsis txhob overlapping thiab ua rau hauv pem teb tawv ntawm ob sab pib koom, thiab pab welding.
3. Kev kho cov cuab yeej vuam cua kub. Thaum vuam PVC pem teb tawv, qhov kub ntawm cov cua kub feem ntau yog hloov mus rau ib ncig ntawm 360 ° C. Cov roj kub ntawm cov cuab yeej vuam tuaj yeem dhau los ntawm cov cua sov hlau
Nws tuaj yeem hloov kho los ntawm lub voj voog, thiab tuaj yeem raug kho los ntawm cov iav ntawm qhov ntsuas kub. Txoj hauv kev yooj yim los tswj cov cua sov ntawm qhov vuam yog tswj qhov kev ncua deb ntawm lub vuam teeb thiab vuam seam ntawm qhov deb ntawm 67 hli, thiab khaws cia rau 4s, PVC pem teb tawv yuav tig daj vim cua sov.
4. Thaum vuam, siv cov vuam sib txawv thiab vuam nozzles raws li cov pob qij txha sib txawv. Pav ca seams yog welded nrog puag ncig vuam hlau (Daim duab 4), thiab hloov vuam nozzles yog siv. Daim duab peb sab vuam hlau yog siv rau cov poj niam fillet weld, thiab ib daim duab peb sab vuam taub yuav tsum tau xaiv. Thaum vuam, lub teeb yuav tsum tau inclined ntawm lub kaum sab xis ntawm 30 °. Lub vuam hlau yog perpendicular rau PVC pem teb tawv thiab yog rhuab nyob rau tib lub sij hawm raws li hauv pem teb tawv kom txog rau thaum nws yog me ntsis ci thiab nplaum. Lub sijhawm no, qhov tseeb qhov kub thiab txias ntawm cov vuam hlau thiab cov tawv hauv pem teb yuav tsum tau tswj xyuas. Thaum tshav kub nyob rau hauv qhov sib txawv ntawm lub vuam pas nrig thiab hauv pem teb tawv mus txog ib theem uas ua rau lawv ci me ntsis, ib tug me ntsis siab ntawm lub vuam hlau yuav ua rau nws embedded nyob rau hauv lub weld. Thaum cov cua sov tsim nyog, ntxiv txog 132N quab yuam rau vuam pas nrig, vuam pas nrig yuav khoov mus rau qhov vuam seam, thiab txuas ntxiv txav lub vuam vuam mus rau qhov kev taw qhia ntawm vuam seam, kom cov vuam hlau thiab PVC pem teb tawv. tuaj yeem melted tiaj tus.
zawv zawg weld. Qhov nruab nrab ceev ntawm txoj kev vuam no yog 0.6ms. Thaum lub sij hawm tag nrho cov txheej txheem welding, lub siab ntawm lub vuam hlau yuav tsum tau khaws cia tas li. Thaum lwm lub vuam pas nrig yuav tsum tau txuas nrog, qhov vuam yuav tsum tau nres ua ntej vuam hlau luv dhau los tuav, thiab tom qab ntawd txiav nrog rab riam ntse ntawm qhov chaw sib cuag ntawm vuam hlau thiab PVC pem teb tawv. Lub incision yuav tsum tau txiav mus rau hauv lub kaum sab xis ntawm 60 °, thiab lub vuam pas nrig tshiab yuav tsum tau txiav mus rau hauv 60 lub kaum sab xis, lub pob tw ob lub vuam hlau txiav, thiab ces kub nrog cua kub mus txuas ntxiv vuam. Thaum kawg ntawm vuam, qhov chaw sib cuag ntawm cov vuam hlau thiab PVC pem teb tawv yuav tsum tau rhuab sai sai, lub zog ntawm vuam hlau yuav tsum tau nres, lub vuam teeb yuav tsum tau muab tshem tawm, thiab lub siab ntawm vuam pas nrig yuav tsum tau khaws cia. kom txog thaum lub vuam seam txias thiab cov vuam hlau yuav tsum raug txiav tawm. Rau lub tiaj tiaj vuam, ib feem ntawm cov vuam hlau protruding los ntawm cov tawv hauv pem teb yog txiav tiaj tus nrog ib tug crescent riam, thiab sab hauv fillet weld tsis tas yuav tsum tau ua tom qab vuam.
Lub zoo meej vuam seam ntawm PVC yas pem teb tawv yuav tsum tsis txhob xim av los yog wrinkled. Qhov tshwm sim no qhia tau hais tias qhov vuam kub siab dhau lawm. Yog hais tias qhov loj thiab cov duab ntawm cov vuam hlau zoo ib yam li thaum nws tsis tau rhuab, nws txhais tau hais tias lub tshav kub tsis txaus thaum vuam. Ib qho zoo weld yuav tsum qhia me me streamlines los yog ripples ntawm ob sab ntawm lub weld, qhia tau hais tias lub vuam pas nrig nrog lub siab thiab cua sov yog kiag li haum rau PVC pem teb tawv. Lub weld yuav tsum ncaj thiab tsim. Qhov ncaj ntawm qhov vuam yuav tsum tsis txhob siab tshaj 1.5mm ib 'meter'. Tsis tas li ntawd, thaum ua haujlwm ntev thiab ncaj welding, koj tuaj yeem siv txoj hlua vuam ceev, thiab xaiv qhov vuam ceev ceev yuav ua tau li 6 npaug sai dua li kev tuav vuam. Qhov ceev vuam nozzle heats lub phaj ua ntej vuam, thiab muaj ib tug mechanism rau nias lub vuam hlau, yog li tsis tas yuav nias lub vuam hlau los ntawm tes.
Kev txhim kho zoo ntawm cov neeg caij tsheb hauv pem teb thiab hauv pem teb tawv ncaj qha cuam tshuam rau qhov zoo ntawm sab hauv ntawm lub tsheb. Yog li ntawd, nws yuav tsum nruj me ntsis ua raws li cov txheej txheem kev npaj thiab txheej txheem thaum paving hauv pem teb thiab hauv pem teb tawv kom ntseeg tau qhov zoo ntawm kev teeb tsa thiab txhim kho kev ua haujlwm.
eco lub tuam txhab yog cov kws tshaj lij tsheb npav pvc pem teb tawv muag (nyem daim duab hauv qab no kom paub meej)
