Qhov rai foob rau yas profile plays lub luag haujlwm ntawm rwb thaiv tsev, tiv thaiv qhov chaw sab hauv los ntawm cov suab nrov sab nraud, txias, cua, thiab noo noo. Koj tuaj yeem siv nws hauv qhov rais ntawm cov tsev rau txhua lub hom phiaj. Tsis ntev los no, cov neeg nyob hauv cov tsev niaj hnub thiab cov tsev nyob tau pib txhim kho cov qhov rais yas, uas txawv ntawm kev ua tau zoo thiab kev ua haujlwm ntawm lawv cov ntoo counterparts. Nrog lawv cov kev pab, koj tuaj yeem txo tus nqi ntawm cov kev pabcuam cua sov. Tab sis dhau sijhawm, txhua yam, txawm tias qhov zoo tshaj plaws tuaj yeem ua tsis tiav, thiab cov qhov rais yas tsis muaj qhov tshwj xeeb. Roj hmab foob thiab lwm yam khoom siv niaj hnub no yuav tsum tau saib xyuas raws sijhawm.
Kev piav qhia
Qhov rai foob tiv thaiv cov khoom txawv teb chaws nkag mus hauv chav. Nrog nws, koj tuaj yeem tiv thaiv cov fittings los ntawm ya raws, uas tuaj yeem rhuav tshem nws. Sealing ntsiab muaj lub zog siab, uas yog qee zaum piv nrogCov khoom ntawm vulcanized roj hmab. Xws li cov ntsaws ruaj ruaj tuaj yeem siv rau ntau qhov kub thiab txias, uas txawv ntawm -40 txog +55 ° C. Cov ntsiab lus no tiv taus deformation, lawv yog ib puag ncig tus phooj ywg, thiab lawv cov peev txheej yog qhov dav heev. Yog hais tias peb tham txog ib puag ncig tus phooj ywg, ces lub qhov rais seal tsis muaj cov ntsiab lus uas yuav ua rau lom. Los ntawm kev mus xyuas lub khw, koj tuaj yeem xaiv cov xim ntawm lub foob, uas yuav phim qhov ntxoov ntxoo ntawm lub qhov rais ncej.
Specifications
Qhov rai ntsaws ruaj ruaj tuaj yeem kav ntev txog 30 xyoo, thiab kev ua haujlwm kub yuav txawv nyob ntawm cov cuab yeej tsim khoom. Cov khoom nyob rau hauv lub plawv ntawm lub caij no tsis yog li rhiab heev rau ozone thiab ultraviolet hluav taws xob. Cov kev qhia tshwj xeeb ntawm cov khoom sib txawv ntawm cov ntsaws ruaj ruaj yuav txawv, yog li yuav tsum tau saib xyuas tshwj xeeb rau qhov teeb meem no.
Xaiv los ntawm cov khoom siv: roj hmab thiab silicone seals
Lub thev naus laus zis ntawm kev tsim cov roj hmab foob nrog lub vulcanization ntawm roj hmab siv cov sulfur thiab ultraviolet lub teeb. Cov khoom tseem ceeb yog soot; cov ntsiab lus no tuaj yeem siv tau 30 xyoo. Qhov no version ntawm lub foob muab sealing tag nrho cov pob qij txha uas twb muaj lawm.
Silicon npaj tau 10 xyoo ntev dua. Hauv kev tsim cov khoom siv no, cov ntaub ntawv zoo ib puag ncig yog siv, uas muaj zog tiv taus kub heev. Cov khoom tsis ploj thaum lub sijhawm ua haujlwm, txawm tias qhov kub ntawm -40 txog +150 ° C. Cov khoom siv tiv taus tshav ntuj, oxygen thiab ozone.
EPDM thiab TPE seals
Qhov rai foob rau lub qhov rais yas tuaj yeem ua los ntawm ethylene propylene. Lub neej kev pab cuam nyob rau hauv cov ntaub ntawv no mus txog 20 xyoo, cov khoom yog resistant rau atmospheric yam thiab tsis tawg, uas tso cai rau nws yuav siv tau zoo rau nws lub hom phiaj. Thaum cov khoom siv raws li cov thermoplastic elastomers, lub npe suab zoo li TPE, thaum cov khoom tshwm sim nws tus kheej li roj hmab, raws li kev hloov kho hluavtaws polymers.
Ntawm ntawm PVC foob
Qhov rai foob, qhov profile twg tuaj yeem tiv thaiv tau zoo thiab tiv thaiv, tuaj yeem ua los ntawm PVC, uas muaj ntau yam zoo thiab qee qhov tsis zoo. Nws tuaj yeem siv tshwj xeeb hauv thaj chaw sov, tab sis lub sijhawm ua haujlwm tsuas yog 3 xyoos. Kev tsim tshuab yog yooj yim heev piv rau cov analogues, uas muaj txiaj ntsig zoo ntawm tus nqi, uas, hmoov tsis, tsis tuaj yeem hais txog qhov zoo.
Yuav tsum hloov foob
Cov roj hmab rau lub qhov rais yuav tsum tau hloov yog tias koj pom tias muaj cov cua ntsawj ntshab hauv cov chav, muaj qhov sib xyaw ua ke ntawm cov iav, thiab lub qhov rais lawv tus kheej tau pib khov. Nyob rau sab hauv, yog li ntawd,Frost, uas ua rau kom ua tiav lossis ib nrab hnav ntawm cov roj hmab sealing. Condensation tuaj yeem tsim tau yog tias lub sash kaw tsis zoo, ua rau qhov kub thiab txias ntawm cov panes poob, uas ua rau muaj kev ya raws.
Kev hloov pauv lub foob
Yog tias lub qhov rais silicone ua tsis tiav, poob nws cov khoom thiab tsis tiv thaiv qhov profile, ces nws yuav tsum tau hloov. Txhawm rau ua qhov no, koj yuav tsum siv qee cov khoom siv thiab cov cuab yeej, ntawm lawv:
- txiav txiab;
- kawg;
- khoom siv sealing.
Thaum lub qub foob tau raug tshem tawm, lub qhov hws yuav tsum tau ntxuav kom huv, rau qhov no koj tuaj yeem siv txhuam txhuam. Tom qab ntawd cov grooves yog wiped nrog ib tug damp daim ntaub, thiab ces qhuav zoo. Cov ces kaum tau ua tiav nrog cov kua nplaum, kev ua haujlwm kuj tseem ua haujlwm nyob rau hauv cov chaw uas cov khoom tshiab yuav raug kho. Cov hlua yuav tsum muaj zog, nws yog ib qho tseem ceeb uas yuav tsum tau txiav tawm ntau dhau nrog txiab, thiab txuas cov pob qij txha uas siv cov kua nplaum.
Cov lus qhia tshwj xeeb
Lub foob rau lub qhov rais thav duab yuav tsum tsis txhob ncab thaum lub sijhawm teeb tsa. Qhov yuav tsum tau hloov lub foob tuaj yeem zam tau los ntawm kev kho lub foob; rau qhov no, tus yuam sij raug ntsia rau hauv qhov tshwj xeeb uas tau tsim thiab tig mus kom txog thaum qhov kev xav tau. Yog tias cov txheej txheem no tsis tso cai kom ua tiav cov txiaj ntsig xav tau, tom qab ntawd thawj theem ntawm lub qhov rais sash raug tshem tawm, nws yog qhov zoo tshaj los ua qhov no pib ntawm lub pob khawm sab saum toj. Tom ntej no, lub qub foob raug tshem tawm,thiab tom qab ntawd ib qho tshiab raug ntsia rau hauv qhov zawj, thaum nws yuav tsum tau ua maj mam.
Thaum lub qhov rais roj hmab ntsaws ruaj ruaj, tsis tas yuav tshem cov kua nplaum qub. Nws yog qhov zoo dua los thov ib txheej tshiab. Koj yuav tsum tsis txhob maj thaum lub sijhawm txheej txheem no, vim tias cov kua nplaum tuaj yeem smeared. Koj yuav tsum tau tos kom qhov sib tov kom qhuav tag, tsuas yog tom qab ntawd nws pom zoo kom nruab lub qhov rais sash rau hauv qhov chaw. Yog tias nws hloov tawm tias cov roj hmab qub qub tsis hnav tag nrho thiab tseem tuaj yeem siv tau, nws raug nquahu kom rov kho lub foob, rau qhov no nws yog lubricated nrog aerosol lubricant.
cov lus pom zoo ntxiv rau kev xaiv lub foob
Yog koj tseem tsis paub xaiv lub foob twg, koj yuav tsum ua tib zoo saib xyuas cov yam ntxwv ntawm txhua tus ntawm lawv. Piv txwv li, polymer yog ua los ntawm cov khoom zoo polyvinyl chloride, tab sis muaj qhov tsis zoo ntawm kev ua haujlwm siab rau huab cua tsis zoo. Nyob rau hauv lub caij ntuj sov, xws li ib tug foob softens, thiab nyob rau hauv lub caij ntuj no nws hardens, ntawm lwm yam, nws yog raug rau tshav ntuj. Tab sis roj hmab thiab roj hmab ntsaws ruaj ruaj yog qhov txhim khu kev qha thiab ntau yam hauv kev ua haujlwm. Lawv muaj cov yam ntxwv ntawm kev tiv thaiv qhov kub thiab txias. Ultraviolet tsis cuam tshuam rau cov ntsaws ruaj ruaj, lawv muaj kev hnav tsis kam. Self-adhesive qhov rais foob tuaj yeem ua los ntawm polyethylene nrog npuas roj hmab. Cov khoom no tsis tshua muaj tshwm sim vim tsis zoo thiab ntau yam me me ntawm cov duab. Qhov kim tshaj plaws yog silicone, yog li nws tsis yog nyob rau hauv xws li kev thov siab. Cov khoom siv yog huab cua resistanttej yam kev mob, muaj kev ruaj ntseg siab thiab tsis zoo rau cov roj hmab foob nyob rau hauv cov nqe lus ntawm mechanical raug. Tsis zoo EPDM foob muab cua qis thiab tiv thaiv suab nrov.
Zaj lus
Lub neej kev pabcuam ntawm cov pos hniav yuav nyob ntawm qhov tsis zoo ntawm sab nraud, tab sis kuj yog kev saib xyuas kom raug. Txhawm rau kom lub neej ntev ntawm lub qhov rais no, nws yog ib qho tsim nyog yuav tsum ua kom huv si. Ua li no, raws li qhov tsim nyog, qhov saum npoo ntawm lub foob yog ntxuav ntawm av thiab hmoov av, lubricated nrog silicone gel. Xws li kev ua haujlwm yuav tsum tau ua ob peb zaug hauv ib xyoos, tsuas yog nyob rau hauv cov xwm txheej zoo li no nws yuav tuaj yeem hloov cov roj hmab band tsawg dua.
