Kuv tuaj yeem txheeb xyuas cov khoom siv PET zoo li cas?

Raws li cov khoom siv yas, PET feem ntau muaj polyethylene terephthalate PET thiab polybutylene terephthalate PBT. polyethylene terephthalate kuj tseem hu ua polyester cob. PET tau hnov ​​​​ntau hauv lub neej niaj hnub, tab sis tsis muaj coob tus neeg paub yuav ua li cas txheeb xyuas cov khoom siv yas zoo PET.
PET yog lub mis dawb los yog lub teeb daj uas muaj crystalline polymer nrog lub ntsej muag du thiab ci. Creep tsis kam, qaug zog tiv thaiv, kev sib txhuam zoo, hnav me me thiab siab tawv, nrog cov thermoplastics hauv toughness; hluav taws xob rwb thaiv tsev kev ua tau zoo, cuam tshuam los ntawm qhov kub thiab txias me me, tab sis tsis zoo corona kuj. Non-toxic, huab cua resistant, zoo stability tiv thaiv tshuaj, siab hygroscopicity, ziab ua ntej molding yog tsim nyog. Tiv thaiv kom tsis muaj zog acids thiab cov kuab tshuaj organic, tab sis tsis ua rau thermal immersion hauv dej thiab tsis alkalis.
PET resin muaj qhov kub hloov pauv ntawm iav, qeeb crystallisation, ntev molding cycles, ntev kev voj voog, siab molding shrinkage, tsis zoo seem stability, crystallized molding yog nkig, tsis kub tsis kam, thiab lwm yam.
Los ntawm cov neeg ua haujlwm nucleating nrog rau cov tshuaj crystallising thiab cov iav fiber ntau txhim kho, PET muaj cov khoom ntawm PBT ntxiv rau cov hauv qab no PET cov txheej txheem kev txheeb xyuas cov yas:
1, Ua ntej hnov ​​​​tsw tsw ntxhiab, PET saj txawv ntawm cov yas dav dav, hlawv nws nrog lub teeb, ces koj yuav hnov ​​​​tsw tsw qab thiab xis nyob (kub lub raj mis kom tsis txhob hnov ​​​​qab), yog tias PET muaj lwm cov khoom xyaw, cov ntxhiab tsw heev. nkoos. Yog tias PET muaj lwm cov khoom xyaw, cov ntxhiab tsw yuav pungent. Qee lub raj mis muaj SEBS cov khoom xyaw thiab siv tsis tau.
2, rub cov lo lo ntxhuav, thaum kub hnyiab ntawm qhov sib zog rub cov lo lo ntxhuav, saib seb cov lo lo ntxhuav ntev ntev, thiab rub cov lo lo ntxhuav tawm ntawm qhov tawg, saib qhov nruab nrab ntawm qhov tawg, cov txhob lo lo ntxhuav tsis dov rau hauv lub voj voog me me, ntau yob qhia tau hais tias lub siab melting point.
3, saib qhov kub hnyiab, yog tias cov xim dub ntau dhau los yog cov roj drips sai, feem ntau cov ntsiab lus melting tsis zoo, uas feem ntau pom muaj nyob rau hauv PET zaj duab xis flakes.
Tab sis feem ntau yog tias nws yog lub raj mis flake, yuav tsum tsis txhob muaj teeb meem loj. Lub ntsiab lus tseem ceeb yog qhia yog tias nws muaj PVC, uas yog Achilles lub pob taws ntawm PET. Ua ntej coj ib qho qauv thiab tom qab ntawd muab nws tso rau hauv qhov chaw tshav ntuj. PVC yog lub teeb xiav nyob rau hauv tshav ntuj. Yog folded nyob rau hauv ib nrab yuav muaj ib tug dawb crease. Cov saum toj no yog qhov pom kev pom, uas yog txwv rau qhov raug thiab nyob ntawm qhov kev paub dhau los.
Yog tias cov khoom muaj PVC, yuav muaj ntau qhov xim daj ntawm qhov chaw; Yog hais tias lub melting point tsis txaus, nws yuav yaj sai heev.
Qhov tseeb ua PET kuj suav nrog ntau yam, xws li PET crushed zaj duab xis los ntawm txawv teb chaws factories, slurry block khoom, yob ntawm zaj duab xis ntev dua 30 cm, tag nrho cov uas muaj ntau pab pawg neeg.
Kev txheeb xyuas cov khoom no xav tau kev siv lub qhov cub los sim lawv. Tshwj xeeb, PET yob yog ib qho khoom tsis tshua muaj thoob plaws hauv kev ua lag luam, feem ntau ntawm qhov ntev ntawm 80 mus rau 120 cm lossis ntau dua, thiab tus nqi ntawm cov khoom zoo PET yas raw khoom nrog lub thickness ntawm 3-5 filaments kuj yog heev. siab (dawb thiab pob tshab).
Kawm paub txheeb xyuas cov ntaub ntawv yas PET, koj tuaj yeem nrhiav tau cov khoom zoo yas zoo.
