Lub ntiaj teb niaj hnub no tsis tuaj yeem xav txog yam tsis muaj yas uas tau nyab rau txhua qhov ntawm peb lub neej. Ib feem loj ntawm qhov "hiav txwv yas" no yog tsim los ntawm ntau yam khoom siv zaj duab xis, suav nrog cov yeeb yaj kiab uas qhia tau, uas xav tau hauv ntau lub lag luam.

Nta thiab cov khoom

Polyethylene kev ua yeeb yaj kiab yog qhov tshwm sim ntawm kev rov ua dua ntawm qib thib ob hwm qib polyethylene lossis pov tseg ntawm nws cov khoom. Nws tsis siv rau ntim tshuaj thiab khoom noj. Tshaj tawm qhov sib txawv tshaj plaws ntawm cov txuj ci sib txawv thiab cov khoom lag luam ntawm qib thawj thiab qib siab tshaj plaws yog qhov pom . Zaj duab xis tsis zoo li pob tshab, suav nrog qhov tsis tau yaj, lawv cov nyiaj nyob ntawm qib kev ua kom huv. Nrog polyethylene rov ua dua tshiab, cov tuab tuab tsis zoo ib yam raug tso cai. Tab sis hais txog cov khoom siv dag zog, cov khoom siv nyiaj txiag no tsis qis dua thawj polyethylene.

Cov khoom tiav tsis yog cov khoom muaj tshuaj lom, tab sis kev tso tawm cov pa phem tuaj yeem ua rau cov txheej txheem rov ua dua tshiab . Tsis muaj kev ceev faj yuav tsum tau siv rau sab hauv tsev lossis sab nraum zoov, tshwj tsis yog laj kab tiv thaiv qhib hluav taws. Zaj duab xis yog cov khoom kub heev. Thaum hluav taws kub, polyethylene hlawv thiab yaj, tso tawm aldehydes txaus ntshai.

Rau cov yeeb yaj kiab siv hauv kev ua tiav, rwb thaiv tsev ua haujlwm hauv thaj chaw, yuav tsum muaj daim ntawv pov thawj hluav taws ntawm kev ua raws, uas tswj hwm kev nyab xeeb ntawm cov khoom.

Cov yam ntxwv tseem ceeb ntawm cov yeeb yaj kiab muaj:

• ntxhiab tsw tshwj xeeb (tsis qhia tias muaj tshuaj lom);
• ntxhib nto;
• qis (hauv kev sib piv nrog qib 1) qib ntawm lub teeb pom kev zoo;
• qhov ntxoov ntxoo los ntawm me ntsis grey lossis daj rau xim thiab dub (nrog rau ntxiv cov zas xim los yog soot);
• ya raws tsis kam;
• nruj;
• lub cev hnyav;
• tiv taus kub ntawm -60 txog + 60 °;
• zoo tensile zog thiab tensile zog nyob rau hauv longitudinal thiab transverse qhia;
• kev puas tsuaj kuj tseem loj hlob nyob ntawm qhov tuab;
• tus nqi qis;
• ntau yam ntawm;
• lub sijhawm lav ntawm kev ua haujlwm - los ntawm 3 xyoos lossis ntau dua.

Kev laus ntawm polyethylene tshwm sim los ntawm tshav ntuj: cov khoom ua npub thiab nkig. Ntxiv lub teeb ruaj khov pab daws qhov teeb meem.

Ntau lawm

Lub ntsiab tsis zoo ntawm cov yas polymers yog lub sijhawm ntev ntawm lawv qhov kev sib tsoo ntuj. Los ntawm suav nrog hauv kev tsim tshwj xeeb biodegradable additives, cov txheej txheem no tuaj yeem ua kom nrawm dua, tab sis tseem yog lub ntiaj teb uas yog cia li suffocating los ntawm cov pov tseg. Tsis ntev los no, yas tau muab pov tseg tsuas yog 2, qhov tseeb, txoj kev tsis zoo: kev hlawv thiab faus neeg.

Recycling cov ntaub ntawv kom tau txais cov yeeb yaj kiab zoo yog kev daws teeb meem zoo uas yog kev lag luam thiab ib puag ncig zoo. Cov khoom siv rov ua dua tshiab rau rov ua dua polyethylene:

• cov khoom siv tsis tau lees paub tias yog kev tsim khoom tsis raug;
• cov khoom pov tseg ntawm tib hom;
• txheeb pov tseg.

Kev tsis lees paub hauv kev tsim ua ib feem me me ntawm tag nrho cov khoom siv raw: kwv yees li 10%. Yog li ntawd, thaum lub sijhawm ua haujlwm, kev txheeb thiab ua kom huv ntawm cov polymers uas twb tau siv lawm yog nyob rau ntawm qhov xub ntiag. Cov txheej txheem ntawm rov ua dua polyethylene hauv kev tsim khoom zoo li no:

• sau cov khoom rov ua dua tshiab tau txheeb, ntxuav thiab ntxuav;
• cov khoom yog crushed nyob rau hauv ib tug crusher;
• tshem tawm cov dej tsis huv ntau dhau thiab noo noo siv lub centrifuge;
• kom huv si qhuav;
• hauv granulator lossis agglomerator, granules lossis agglomerate (polyethylene crumb) tau tsim los ntawm cov khoom siv yaj.

Agglomerator yog cov cuab yeej tshwj xeeb uas tuaj yeem muaj qhov yooj yim tsim nrog phau ntawv thauj khoom ntawm cov ntaub ntawv raw thiab dej, lossis ua ib lub computer computer nyuaj . Cov khoom siv raw polymer yaj hauv cov agglomerator tau txias los ntawm kev poob siab ntawm cov dej txias, thaum sib sau ua ib hom flakes (agglomerate). Cov khoom tau txais hauv granulator thiab agglomerator sib txawv. Piv txwv li, qhov meej ntawm cov granules thib ob yuav siab dua li ntawm cov agglomerate.

Thiab tseem cov granules muaj cov qauv zoo sib xws thiab ntau qhov ntom ntom. Cov yeeb yaj kiab tsim los ntawm lawv yuav qis dua me ntsis rau cov khoom siv thawj hauv qhov zoo thiab pob tshab . Cov khoom kawg yog tau los ntawm kev thawb cov crumb rau hauv lub tshuab extruder thiab hla nws los ntawm cov ntsia hlau ntawm qhov kub thiab txias. Tom qab ntawd zaj duab xis web dhau los ntawm kev tsim lub taub hau ntawm cov ntawv sib txawv, txias, tsis so ntawm cov menyuam thiab npaj rau kev faib rau cov khw muag khoom hauv cov yob.

Hom kev txheeb xyuas

Kev faib tawm ntawm cov yeeb yaj kiab kev ua haujlwm nyob ntawm lawv cov muaj pes tsawg leeg. Thaum rov ua dua tshiab, cov khoom tsim los ntawm cov khoom siv yuav nyob ntawm qhov khoom siv raw: nws tsis tuaj yeem hloov LDPE (siab siab) polyethylene tom qab rov ua dua tshiab rau hauv HDPE (tsis tshua muaj siab) thiab hloov pauv.

Qhov dav tshaj plaws ntawm cov ntawv polyethylene yog 6000 hli. Qhov dav rau qib B thiab B1 yog 3000 mm thiab ntau dua, rau SIK qeb - 1500 mm thiab ntau dua, rau SM - ntau dua 800 mm. Qhov ntev ntawm cov yeeb yaj kiab hauv ib yob yog los ntawm 50 txog 200 m. Cov yam ntxwv tseem ceeb yog qhov tuab, nws tau ntsuas hauv microns (microns). Cov cim ntsuas nrov tshaj plaws: 80 microns, 100 microns, 150 microns, 200 microns. Cov yeeb yaj kiab tau tsim tawm raws li kev qhia tshwj xeeb lossis cov qauv hauv qab no:

• kev polyethylene zaj duab xis GOST 10354-82;
• ntsws zaj duab xis GOST 25951-83;
• HDPE GOST16338-85;
• LDPE GOST 116337-77.

Cov txheej txheem kev tsim cov yeeb yaj kiab:

• cov canvas yog cov khoom siv txuas ntxiv tsis muaj qhov quav;
• lub tes tsho - polyethylene yeeb nkab, tsim nrog quav quav - quav lossis tsis muaj lawv;
• ib nrab-lub tes tsho (qhov no yog lub tes tsho txiav ntawm ib sab raws cov quav), nws tuaj yeem nthuav dav mus rau hauv daim ntaub khov.

Lwm qhov kev faib tawm faib cov khoom lag luam rau hauv cov npe uas tau siv rau lub hom phiaj sib txawv:

• M - hom khoom siv hauv kev tsim cov hnab;
• T - ntau hauv kev tsim kho;
• ST thiab SIK - xav tau kev npaj tsev cog khoom, tsev cog khoom;
• SK - rau kev txuag tsiaj hauv kev ua tsiaj, ua liaj ua teb tsiaj;
• SM - rau npog hauv av txhawm rau khaws cov dej noo (mulching);
• В, В1 - hauv kev rov ua av thiab tswj dej;
• H - rau tsev neeg siv ua khoom ntim khoom.

Cov cheeb tsam ntawm kev siv

Cov yeeb yaj kiab txuj ci ua haujlwm raws li kev daws teeb meem thoob ntiaj teb rau ntau yam teeb meem ntawm kev ua liaj ua teb thiab siv:

• thaum mulching cov av;
• rau kev tiv thaiv lub tsev xog paj thiab haylages;
• thaum npaj cov ntxaij lim dej thiab cov kav dej phwj tuaj, cov dej ntws;
• rau kev khaws thiab thauj cov khoom lag luam ua liaj ua teb.

Cov khoom no yog qhov xav tau zoo hauv kev tsim kho. Txhua leej txhua tus tau pom scaffolding them nrog polyethylene. Hauv kev tiv thaiv zoo li no, koj tuaj yeem ua haujlwm txuas ntxiv txawm tias huab cua tsis zoo. Cov txuj ci yeeb yaj kiab dub ua lub luag haujlwm ntawm cov khoom siv insulating zoo hauv kev siv:

• vov tsev thiab ua haujlwm sab nrauv;
• tso lub hauv paus (rau kev tiv thaiv los ntawm dej hauv av);
• tso cov kav dej.

Polyethylene rau kev tiv thaiv dej yog qhov zoo vim tias nws yog nyias, tab sis ntom, tsis rot thiab tsis muaj kev cuam tshuam rau kev ua ntawm cov kab mob. Cov khoom siv hauv tsev uas tsis thauj khoom mus rau ntawm qhov chaw tau tiv thaiv los ntawm nag thiab hnub nrog cov ntawv yas. Tsis yog kev kho dua ib sab hauv lossis sab nraud ntawm thaj chaw tau ua tiav yam tsis muaj cov yeeb yaj kiab, uas yog siv los dai qhov rais thiab phab ntsa, npog hauv pem teb thiab rooj tog kom lawv tsis txhob muaj plua plav, plaster thiab pleev xim. Ntau yam kev thov - ntim txhua yam khoom lag luam uas tsis yog khoom noj, xws li:

• qhov rai thiab qhov rooj thaiv;
• cov ntaub ntawv tiav (ntawv ntsa, nplaum, sib xyaw);
• yob ntawm ntaub;
• ntawv, ntawv thiab ntawv sau;
• rooj tog;
• Khoom siv;
• tshuaj lom neeg hauv tsev;
• ntau yam cuab yeej thiab cuab yeej.

Cov yeeb yaj kiab ua lub luag haujlwm tiv thaiv ntxiv rau cov thawv ntawv thawv, ua kom nruj thiab nyab xeeb ntawm cov ntsiab lus. Hauv ib lub tsev twg koj tuaj yeem pom cov hnab khib nyiab ua los ntawm cov txheej txheem polyethylene ntawm ntau lub peev xwm.

Tus nqi pheej yig, ntau yam sib txawv, kev yooj yim ntawm kev siv ua cov khoom no txaus nyiam hauv ntau lub lag luam thiab hauv peb lub neej niaj hnub.
