Ib. Teeb meem xim daj
1.Lub PVC nws tus kheej tsis ruaj khov
Yog tias nws yog cov chaw tsim khoom PVC tshiab, nws yuav yog PVC nws tus kheej ruaj khov thiab tsis zoo, koj tuaj yeem hloov PVC sim. Txawm li cas los xij, txawm tias lub npe PVC siv yuav tshwm sim los ntawm PVC resin nws tus kheej, vim tias txawm tias PVC ua los ntawm tib lub chaw tsim khoom, cov khoom sib txawv ntawm qhov zoo yuav txawv.
2. Tsis muaj stabilizer
3.Qhov ntsuas kub muaj teeb meem
Nws qhia tau hais tias qhov kub thiab txias qis dua qhov tseeb, qhov kub thiab txias yuav ua rau PVC decomposition thiab daj. Nyob rau lub sijhawm no, koj yuav tsum rov kuaj xyuas qhov ntsuas kub ntau dua. Cov txheej txheem yog yooj yim heev, nrog lub ntsuas kub mercury. Hauv kev tsim khoom tiag tiag, vim yog cov thermocouple xoob, cov ntaub ntawv nplaum thiab lwm yam laj thawj, yuav ua rau lub ntsuas kub ntawm qhov ntsuas kub thiab qhov sib txawv tiag tiag. Tsis tas li ntawd, nws raug nquahu kom siv lub ntsuas kub zoo.
2: Daim ntawv muaj cov npuas me me
1.PVC noo noo ntau dhau nyob rau hauv cov ntaub ntawv raw: xws li nyob rau hauv lub rainy hnub nyob rau hauv lub caij ntuj sov, raw cov ntaub ntawv raug cuam tshuam los ntawm noo noo, uas yog, cov dej yuav tsis tau tag nrho tawm nyob rau hauv lub tog raj kheej, tshav kub expansion, thiab ces tsim npuas nyob rau hauv daim ntawv. .
2. Tsis tas li ntawd, cov tshuaj ntxiv kuj tseem muaj cov dej ntau dhau
Txhawm rau ua kom tiav, cov kev daws teeb meem tuaj yeem siv tau: tsim nyog txuas lub sijhawm sib xyaw ntawm cov khoom siv thermal, thiab siv lub tshuab cua txias. Muaj peev xwm tshem tawm cov dej noo los ntawm cov khoom siv raw.
3: Tus lej siv lead ua nyob rau hauv daim ntawv tshaj tus qauv, tseem hu ua ntses qhov muag
Cov laj thawj feem ntau rau cov pob zeb siv lead ua yog: qee qhov PVC resin hais tsis yog plasticize, lossis plasticization tsis zoo. Cov laj thawj rau kev tsim yog: PVC resin nws tus kheej tsis zoo. Yog tsis muaj kev hloov ntawm PVC cob, cov kev daws teeb meem yog:
1.Extend lub sij hawm sib tov thiab nce qhov sib tov kub kom tsim nyog los txhawb kev nqus ntawm additives. Thiab kev siv cov khoom sib tov zoo, chav tsev sib xyaw ntawm cov khoom siv ua ntej plasticizing, yog irreplaceable.
2.Cov khoom xyaw sib xyaw tuaj yeem ua rau ib nrab hnub lossis ib hnub ua ntej siv
3.Nws tuaj yeem txhim kho qhov kub thiab txias ntawm lub tog raj kheej, ua kom cov ntsia hlau nrawm, ua kom lub qhov ntswg qhov ntswg, thiab ntxiv dag zog rau kev ua haujlwm ntawm plasticizing.
4.Nyob rau hauv cov ntsiab lus ntawm cov mis, peb yuav tsum ua tib zoo xaiv qhov tsim nyog additives thiab ntau npaum li cas ntawm additives. Tam sim no, kev ua lag luam additives kuj chaotic, thiab cov khoom zoo sib txawv heev. Nws yuav tsum tau ua tib zoo xaiv kom pom qhov sib npaug zoo dua ntawm tus nqi thiab kev ua haujlwm.
Feem ntau, xav txog ntau yam laj thawj saum toj no, xaiv qhov kev daws teeb meem zoo tshaj plaws. Qee qhov kev daws teeb meem muaj kev sib raug zoo, xws li nce qhov kub thiab txias tuaj yeem ua rau daim ntawv daj, ntau stabilizer yuav ua rau tus nqi nce. Tsuas yog hauv kev xyaum los tshawb nrhiav txoj hauv kev mus tom ntej.
