Yuav Ua Li Cas Paub Qhov Tseeb Thiab Qhov False Door Thiab Window Seals?

Lub ntsiab tseem ceeb ntawm lub qhov rooj thiab qhov rais yog sealing, thiab lub sealing sawb plays lub luag haujlwm tseem ceeb. Cov khoom siv ntawm cov hlua khi siv hauv kev ua lag luam feem ntau hloov kho los ntawm PVC. Hauv cov PVC mos, nws lub luag haujlwm tseem ceeb yog tsis muaj dab tsi ntau tshaj li qhov zoo ntawm cov yas ntxiv rau nws. Tam sim no, cov plasticizer ruaj khov yog dioctyl phospophthalate. Rog, dibutyl.

Txawm li cas los xij, tam sim no tus nqi lag luam yog siab heev, thiab qee cov tub lag luam uas tsis paub cai siv qee yam khoom pheej yig los hloov (cov roj cav khib nyiab, roj hauv paus sab laug los ntawm cov roj refineries, thiab lwm yam), uas ua rau muaj kev phom sij rau cov neeg siv khoom.

Cov tsos mob ntawm nws cov khoom:

1. Qhov tshwm sim ntawm cov roj seepage thiab nag lossis daus ntawm qhov chaw tshwm sim. Cov roj khib nyiab no tsis sib haum nrog PVC kiag li. Roj yog ib qho yooj yim los tshwm rau ntawm qhov chaw ntawm lub sealing sawb, thiab qhov chaw ntawm qhov profile kuj stained nrog cov kab daj. Tsis yog ib puag ncig tus phooj ywg, muaj ntau cov khoom tsis zoo uas ua rau huab cua phem.

2. Thaum lub npe hu ua plasticizer volatilizes los yog oozes tawm, lub sealing sawb yuav poob nws cov qub softness, ua nyuaj heev, thiab yuav muaj hnub nyoog thiab shrinks sai, yog li ntawd ib tug loj sib txawv tshwm nyob rau hauv lub kaw qhov rooj thiab qhov rais, thiab cov airtightness hloov. Tsis zoo heev (dej to, plua plav to), tshwj xeeb tshaj yog cov hlau hauv ob sab hauv lub qhov rooj thiab qhov rais yuav corroded sai. Ntau tus neeg siv feem ntau pom tias ntau cov kua liab ntws tawm ntawm cov hlaws dai rau hauv lub qhov rais thaum lub caij los nag thiab qias neeg heev, uas yog, lub qhov rooj thiab qhov rais yog to. Yog tias nws yog corroded thaum ntxov, lub neej ntawm lub qhov rooj thiab qhov rais yuav raug txo kom tsawg.

Hauv peb cov txheej txheem tsim khoom, kev nqis peev ntawm cov hlua khi khi rau ib qho me me, tab sis nws lub luag haujlwm tsis tuaj yeem tsis quav ntsej. Yog li kuv xav tias txhua tus neeg yuav tsum tsis txhob xaiv cov khoom cuav no txhawm rau txo tus nqi. Txoj kev txheeb xyuas yog yooj yim heev:

Ua ntej, siv koj lub qhov ntswg kom hnov ​​​​tsw yog tias muaj cov ntxhiab tsw tshwj xeeb. Cov khoom siv PVC ib txwm yuav muaj cov ntxhiab tsw me ntsis, thiab nws yuav luag tsis muaj ntxhiab tsw.

Qhov thib ob, qhwv lub sealing sawb kom nruj raws li qhov ua tau ntawm qhov profile, thiab muab tso rau ntawm qhov kub thiab txias rau lub sijhawm (qhov chaw ntawm lub ru tsev lossis hauv qhov chaw tshav ntuj). Xyuas seb qhov chaw sib chwv ntawm qhov profile nto thiab lub sealing strip yog stained thiab discolored, seb cov plua plav ntawm qhov chaw ntawm lub sealing strip yog daj (nws yog ib qho yooj yim rau nqus av yog tias muaj roj), saib seb nws puas oily, thiab seb ob txhais tes qias neeg.

Thib peb, qee qhov pheej yig sealing strips yuav muaj ntau cov fillers, yog li qhov saum npoo yuav tsis ci heev, thiab cov uas pheej yig heev thiab ci ntsa iab tsis pom zoo.

Plaub, saib qhov tshwj xeeb lub ntiajteb txawj nqus, yuav ua tau pes tsawg meters ib kilogram. Muaj ntau tus neeg ua lag luam uas tsis paub tseeb uas ua haujlwm zoo hauv kev siv cov fillers. Peb feem ntau siv cov fillers nrog lub ntiajteb txawj nqus me me los txo cov nqi (lub teeb calcium carbonate). Cov nplej hnyav yuav tsis hloov ntau, tab sis qee cov tuam ntxhab tau nrhiav ntau dua. (txuag me ntsis hluav taws xob) siv talcum hmoov, hnyav calcium, thiab lwm yam raws li muab tub lim, uas zoo heev tsub kom qhov feem ntawm sealing sawb khoom, (peb cov neeg siv feem ntau yuav los ntawm kilograms thiab siv lawv los ntawm ntev) Qhov no yog tsis pom. Hloov chaw, nws nce tus nqi. Ntxiv hnyav calcium sealing sawb, koj ncab rov qab los ntawm tes ob peb zaug, ib qho me me ntawm cov hmoov dawb yuav tshwm rau saum npoo.
