Qhov txiaj ntsig thiab kev phom sij ntawm cov yas
Plastics yog cov khoom sib txuas macromolecule, uas tseem tuaj yeem raug hu ua macromolecule lossis macromolecule. Lawv tseem muaj npe hu ua plastics lossis resins. Lawv tuaj yeem hloov kho lawv lub cev ywj pheej. Nws yog ib hom khoom siv coj los ua ke los ntawm kev sib tov lossis cov hws ntawm monomer raw cov ntaub ntawv. Nws muaj li ntawm cov khoom siv hluavtaws thiab cov khoom ntxiv xws li cov ntawv ntim khoom, cov tshuab yas, cov tshuab nqus khaub ncaws, roj thiab xim. Nws lub ntsiab tivthaiv yog khoom cua cob.
& nbsp;
Plastics have many excellent properties: 1. Light weight and high specific strength. 2. Good resistance to chemicals. 3. Excellent electrical insulation performance. 4. Excellent silencing and shock absorption. 5. Some plastics have good light transmittance. 6. Some resins and plastics have valuable special properties, etc. In addition, in an economic point of view, plastics also have the advantages of simple production process and form, low capital investment and production cost, and saving a large number of metals and other materials. Therefore, the application of plastics is more and more extensive.
& nbsp;
It & #39;s a pleasure that plastics have so many advantages, which are cheap and convenient, and can be produced in large quantities for the benefit of mankind.

Ua ntej tshaj plaws, cov khoom noj khoom haus yas ntim khoom muaj teeb meem rau tib neeg kev noj qab haus huv. Peb siv lub hnab yas ntim khoom noj tshwj xeeb ntim hauv hnab ntim khoom noj, yog li lwm lub hnab ntim khoom tsis tuaj yeem siv ntim ntim. Piv txwv, polyvinyl chloride plastics yog cov tshuaj lom. Txawm hais tias polyvinyl chloride resin tsis yog - tshuaj lom, nws yog cov tshuaj lom rau ntxiv cov yas thiab cov tshuab ua kom lub zog ruaj khov thaum ua cov plastics.
& nbsp;
Ntxiv rau, cov yas yuav muaj qhov cuam tshuam loj dua nyob ib puag ncig. 30% ntawm cov khoom lag luam yas thoob ntiaj teb yog cov neeg siv khoom pov tseg hauv ntim, tsev neeg thiab liaj teb. Cov khoom lag luam no feem ntau siv rau 1 txog 3 hlis lossis ib nrab xyoo, thiab lub sijhawm ntev tshaj yog tsuas kav ib xyoos. Txawm li cas los xij, feem ntau ntawm cov khoom siv yas pov tseg yog polyolefin, uas yog cov ntaub ntawv inert. Lawv yog qhov tsis haum rau microorganisms thiab tsis yooj yim biodegradable hauv ib puag ncig ntuj. Yog li ntawd, cov khib nyiab ntim pov tseg nyob ntawm txoj kev ntawm lub nroog thiab cov chaw ncig ua si coj kev ua phem rau tib neeg & # 39; s lub zeem muag, cuam tshuam tag nrho kev zoo nkauj ntawm cov nroog thiab cov chaw zoo nkauj, rhuav tshem lub nroog & # 39; s tsos thiab toj roob hauv pes, thiab yog li ua rau & quot; muaj kuab paug rau pom & quot ;. Nyob rau tib lub sijhawm, tom qab pov tseg ntim yas ntim nkag hauv ib puag ncig, nws nyuaj rau thuam, ua rau ntev - lub sijhawm ntev, sib sib zog nqus - zaum qhov teeb meem ib puag ncig cov teeb meem. Ua ntej tshaj plaws, pov tseg cov hnab yas pov tseg sib xyaw rau hauv av, cuam tshuam rau cov qoob loo 'nqus cov zaub mov thiab dej, uas ua rau cov qoob loo txo qis; qhov thib ob, khib nyiab yas ntim pov tseg hauv av lossis dej, nqos khoom noj los ntawm cov tsiaj, ua rau tsiaj tuag.
& nbsp;
Nyob rau tib lub sijhawm, kev tsim yas kuj tseem coj kev nyuaj rau kev npaj cov khoom siv. Dhau ob peb lub xyoos dhau los, cov cuab yeej siv rau cov loj - nplai tsim cov khoom lag luam yas hauv kev lag luam yas tau siv roj. Nws tau tshaj tawm tias kwv yees li 150 lab roj av thiab cov khoom siv roj yog siv hauv kev tsim tshuaj lom neeg ntawm & quot; polymer & quot; txhua txhua xyoo nyob rau hauv lub ntiaj teb. Cov khoom siv roj tsawg. Hauv lub sijhawm ntev, tib neeg kev xav tau siv roj yog tas mus li thiab tsis paub kawg. Ib hnub, cov khoom siv roj yuav yuav sab lim. Nyob rau xyoo tas los no, raws li ntau cov roj loj - tsim cov teb chaws nyob hauv lub ntiaj teb tab tom ntsib teeb meem sab hauv thiab sab nraud: kev ua tsov rog, kev kub ntxhov hauv nroog, kev tsim cov roj poob qis, kev siv hluav taws xob ntawm Tuam Tshoj thiab Is Nrias teb, ob lub tebchaws muaj txiaj ntsig, tau nce mus thov roj, uas ua rau muaj nuj nqis nce siab hauv cov nqi roj. Txoj kev loj hlob no tau ua rau muaj kev cuam tshuam zoo thiab cuam tshuam rau kev xa thiab kev xav tau ntawm kev lag luam yas.
& nbsp;
Yog li ntawd, txhawm rau daws cov teeb meem ntawm ib puag ncig kev ua qias tuaj thiab kev tsis txaus siab, peb tso cov khoom siv rov tom qab yas.
& nbsp;
Dab tsi yas siv? Kev rov ua dua tshiab yas yog txheej txheem ntawm kev rov ua dua tshiab yas thiab siv cov khoom siv dua tshiab. Muaj ob txoj hauv kev los khaws cov hnab yas khib nyiab. Ib qho yog tsim dua tshiab cov plastics mus rau cov khoom siv ntawm cov tsiaj tib lossis los ua rau lawv mus rau hauv monomers, lwm qhov yog ua rau lawv mus rau lwm cov ntaub ntawv lossis lub zog uas tuaj yeem siv synthetically. Ntawm lawv, txoj kev tsim rov qab ncaj qha yog kev ntxuav, zuaj thiab plasticize cov laus yas rau cov txheej txheem ncaj qha lossis pelleting.
& nbsp;
Original from Europe from 2002, with over 140 plastic recycling projects currently in operation, G.E.T Recycling gives you a clear advice with a tailor made solution on the basis of your plastics and requirements.
& nbsp;
GET yog ib qho ntawm koj cov neeg koom tes zoo tshaj plaws hauv kev xa rov qab pib txij li kev sib tham mus nrhiav qhov kev daws teeb meem zoo tshaj plaws, thiab los ntawm cov tshuab tsim khoom lag luam mus txog tom qab - kev pabcuam muag.
& nbsp;
Kev ua tau zoo ntawm kev muaj peev xwm ntau lawm, cov peev txheej txheem cov tshuab ua kom zoo dua ntawm kev nqis peev uas tsim nyog, GET rov qab cov khoom siv thiab cov kab txhawb kev ua haujlwm zoo thiab kev ua haujlwm zoo rau txhua tus neeg siv khoom.
