Mitundu ndi kugwiritsa ntchito matumba a nsalu

Mitundu:

Matumba osoka, Imadziwikanso ngati matumba akhungu. Ndi mtundu wa pulasitiki makamaka womwe umagwiritsidwa ntchito popanga. Zida zake nthawi zambiri zimakhala zamankhwala zopangira pulasitiki monga polyethylene ndi polypropylene.

Zopangira zazikuluzikulu zopanga zakunja ndi polyethylene (pe), pomwe zopangira nyumba ndi polyproplene (ma pp), zomwe ndi utomoni wa ethylene wa Ethylene. M'makampani, zimaphatikizaponso a Ethylene ndi owerengeka a vafins a olera. Polyethylene ndi wopanda fungo, osakhala ndi poizoni, akumva ngati sera, kutentha pang'ono kwa ma acid acids, mayamwidwe ambiri, komanso magetsi osokoneza bongo; Koma polyethylene amasamala kwambiri ndi kupsinjika kwa chilengedwe (zotsatira zamankhwala ndi makina) ndikulimbana ndi mkwiyo. Mphamvu za polyethylene imasiyana pamitundu mitundu, makamaka kutengera kapangidwe kake ndi kachulukidwe. Njira zosiyanasiyana zopangira zimatha kulolera zopangidwa ndi ma proteties osiyanasiyana (0.91 ~ 0.96g / cm3). Polyethylene amatha kukonzedwa pogwiritsa ntchito njira yodziulira ya thermoplastic (onani pulasitiki). Ili ndi magwiritsidwe osiyanasiyana, makamaka ogwiritsidwa ntchito popanga mafilimu oonda, zotengera, mafinya, ma radar, etc. Mu 1983, kuchuluka kwathunthu kwa polyethylene padziko lonse lapansi kunali 24.65mt, ndipo mphamvu ya chomera yomanga inali 3.16MT.

Tsitsi la thermoplastic lomwe limapezeka ndi polymerization wa Propylene. Pali ziwonetsero zitatu: Inoctic, mwachisawawa, ndi syndiotactic, ndi isotactic ngati gawo lalikulu m'malonda a mafakitale. Polypropylene imaphatikizaponso ma provolill a propylene ndi ma ethylene ochepa. Nthawi zambiri semi yowonekera komanso yopanda utoto, yopanda fungo komanso yopanda poizoni. Chifukwa cha kapangidwe kake komanso crystallization yayitali, malo osungunuka ndi okwera kwambiri monga 167 ℃, ndipo ndi kutentha kwa kutentha. Chogulitsacho chimatha kuwonongeka ndi nthunzi, zomwe ndi mwayi wake wabwino kwambiri. Kuchulukitsa ndi 0,90g / masentimita, ndikupangitsa kuti chizipinda chapansi pa chilengedwe chonse. Kukana Kukula, Mphamvu Yachikulu ya 30mpa, ndi Mphamvu Zabwino, Kuuma, ndi kuwonekeranso kuposa polyethylene. Choyipacho ndichabwino kwambiri kupewa kutentha komanso kukayikira kosavuta, koma chitha kugonjetsedwa ndi kusinthidwa ndi kuwonjezera kwa mantioxidantrathalantrateslant motsatana.

Mtundu wa matumba a nsalu nthawi zambiri amakhala oyera kapena imvi yoyera, yopanda poizoni ndi yopanda fungo, ndipo nthawi zambiri imavulaza thanzi laumunthu. Ngakhale kuti amapangidwa ndi mapulamitundu osiyanasiyana, amakhala ndi chitetezo champhamvu zachilengedwe komanso zoyesayesa;

Gwiritsani Ntchito:

1. Matumba opanga feteleza olimba a mafakitale

Chifukwa cha kuchuluka kwazogulitsa ndi mitengo, mabatani 6 biliyoni amagwiritsidwa ntchito mu China ku China chaka chilichonse, kumawerengera 85% ya mitengo yambiri. Ndi chitukuko ndi kugwiritsa ntchito matumba osinthika, matumba ojambulidwa pulasitiki amagwiritsidwa ntchito kwambiri ku mathiraki a zamadzi ndi zogulitsa zamakampani ndi zaulimi. Pa ntchito yaulimi yaulimi,Matumba Otsekemera a Supuni akhala akugwiritsidwa ntchito kwambiri ku Aquatic Plaction, kudyetsa nkhuku za nkhuku, kuphimba zida za mafamu, zida ndi kutetezedwa kwa mbewu zolima, zinthu monga matumba ophatikizika,Matumba ophatikizika, putty ufa ufa wowumbidwa, matumba osoka a urea, etc.

 2. Matumba ogulitsa olima

  Matumba a ma mesh amagwiritsidwa ntchito makamaka paulimi ndipo ndioyenera kugwira mafinya ndi masamba monga maapulo, mapeyala, adc.

3.food matebulo

Kunyamula chakudya monga mpunga ndi ufa kumatengera matumba oluka kuti akwaniritse matumba wamba ophatikizikaMatumba a mpunga, matumba a utoto, matumba otanuma a chimanga, ndi matumba ena ophatikizika.

4.Tirism ndi mafakitale oyendetsa

Mahema osakhalitsa, ma ambulera a dzuwa, matumba osiyanasiyana oyenda, ndi matumba oyenda pamafakitale onse omwe ali ndi ntchito za pulasitiki. Madera osiyanasiyana amagwiritsidwa ntchito ngati chophimba zinthu zonyamula ndi kusungirako, kusinthana ndi tarpoct thonje lonunkhira lomwe limakonda kuwumba. Mipanda ndi Migwirizano yophimba panthawi yomanga imagwiritsidwanso ntchito kwambiri mu nsalu za pulasitiki zopangidwa ndi pulasitiki zimaphatikizira:Matumba a mitengo, Zikwama zam'matanda, matumba onyamula katundu, matumba onyamula katundu, etc

5.Kodi ukadaulo wa 5.

Popeza kukula kwa Geotextles m'ma 1980s, magawo ansalu zopangidwa ndi pulasitikiAdzakulitsidwa, kugwiritsidwa ntchito kwambiri m'madzi ang'onoang'ono amadzi, magetsi, magetsi, ma njanji, magope, migodi, zomanga migodi, ndi gulu lankhondo lankhondo. Mu ntchitozi, geosynthetics ali ndi ntchito monga kusefedwa, ngalande, kulimbikitsidwa, kudzipatula, ndi ma anti-senage. NKHANI YA Pulasitiki ndi mtundu wa geotextile yopanga.

6.flood zowongolera zida

Matumba oluka ndi ofunikira kwambiri osefukira madzi osefukira ndi tsoka. Amakhalanso patsogolo pakumanga mitanda, mitsinje, njanji, ndi misewu yayikulu ndi zikwama za anti News Matumba Ophatikizidwa ndi Chigumula.

7. Zaily Zofunika

Anthu omwe amagwira ntchito zaulimi, zonyamula katundu, ndi msika wophatikizidwa ndi pulasitiki. Pali zinthu zopangidwa ndi pulasitiki kulikonse kumasitolo, nyumba, ndi nyumba. Zinthu zokhala ndi zitsulo zamatamba zamitundu yamatayala zimasinthidwanso ndi nsalu zopangidwa ndi pulasitiki, mongaMatumba ogula, Matumba akuluakulu ogulitsira, ndi matumba apamwamba kwambiri ogula; Matumba ophatikizidwa onyamula katundu, makatani ophatikizika.

8. Matumba a zotumphukira.

Chifukwa cha zinthu zapadera, mafakitale ena angafunike kugwiritsa ntchito matumba a nsalu omwe samagwiritsidwa ntchito kawirikawiri, monga matumba akuda a Carbon. Mbali yayikulu kwambiri ya matumba akuda a Carbor ndi kutetezedwa ndi dzuwa. Matumba akuda a carbon ali ndi mphamvu yoteteza dzuwa kuposa matumba wamba osawoneka, ndipo matumba wamba otata sangathe kulimbana ndi dzuwa nthawi yayitali. Palinsomatumba a anti uv uv: Ndi anti UV Ntchito, ntchito ya Anting, etc.
