Katundu wa Plastics

Mapulasitiki nthawi zambiri amakhala olimba.Atha kukhala amorphous, crystalline, kapena semi crystalline solids (crystallites).
Mapulasitiki nthawi zambiri amakhala opanda kutentha komanso ma conductor magetsi.Ambiri ndi ma insulators amphamvu a dielectric.
Ma polima agalasi nthawi zambiri amakhala olimba (mwachitsanzo, polystyrene).Mapepala owonda a ma polima awa, Komano, atha kugwiritsidwa ntchito ngati mafilimu (mwachitsanzo, polyethylene).
Mukapanikizika, pafupifupi mapulasitiki onse amawonetsa kutalika komwe sikuchira pambuyo pochotsa nkhawa.Izi zimatchedwa "kugwa."
Mapulasitiki amakhala okhalitsa ndipo amawonongeka pang'onopang'ono.

Kugwiritsa Ntchito Plastiki

Ku Nyumba

Pali pulasitiki yochuluka pawailesi yakanema, makina omvera, foni yam'manja, chotsukira chotsuka, komanso mwina mumatope apulasitiki mumipando.Mpando wa pulasitiki kapena mipando ya bar, ma acrylic composite countertops, zomangira za PTFE m'mapoto osaphikira, ndi mapaipi apulasitiki m'madzi.

Magalimoto ndi Transport

Mapulastiki athandizira pazatsopano zambiri zamapangidwe agalimoto, kuphatikiza kukonza chitetezo, magwiridwe antchito, komanso kugwiritsa ntchito mafuta.

Pulasitiki imagwiritsidwa ntchito kwambiri m'masitima, ndege, magalimoto, ngakhalenso sitima zapamadzi, masetilaiti, ndi masiteshoni amlengalenga.Mabampa, ma dashboard, zida za injini, mipando, ndi zitseko ndi zitsanzo zochepa chabe.

Ntchito Yomanga

Pulasitiki akugwiritsidwa ntchito m’njira zosiyanasiyana pomanga.Amakhala ndi kusinthasintha kwakukulu ndipo amaphatikiza chiŵerengero cha mphamvu ndi kulemera kwabwino, kulimba, kutsika mtengo, kukonza pang'ono, ndi kukana kwa dzimbiri, kupanga mapulasitiki kukhala chisankho chokongola pachuma pamakampani omanga.

• Conduit ndi Piping
• Kuyika ndi Mbiri - Kuyika ndi mbiri ya mazenera, zitseko, zokonda ndi masiketi.
• Gaskets ndi zisindikizo
• Insulation

Kupaka

Mapulasitiki osiyanasiyana amagwiritsidwa ntchito kuyika, kutumiza, kusunga, ndi kupereka chakudya ndi zakumwa.Mapulastiki omwe amagwiritsidwa ntchito popanga chakudya amasankhidwa chifukwa cha ntchito yawo: amakhala osagwira ntchito komanso osagwirizana ndi chilengedwe chonse komanso zakudya ndi zakumwa zomwe.

• Zotengera zambiri zamasiku ano zapulasitiki ndi zokutira zidapangidwa mwapadera kuti zizitha kupirira kutentha kwa ma microwave.
• Zotengera zakudya zambiri za pulasitiki zili ndi phindu linanso lotha kusintha kuchokera mufiriji kupita ku microwave kupita ku chotsukira mbale.

Zida Zotetezera Masewera

• Zida zotetezera masewera zimakhala zopepuka komanso zamphamvu, monga zipewa zapulasitiki, zotchingira pakamwa, magalasi, ndi zotchingira zoteteza, kuti aliyense atetezeke.
• Chithovu cha pulasitiki choumbidwa, chosasunthika, chimapangitsa mapazi kukhala okhazikika komanso ochirikizidwa, ndipo zipolopolo zolimba za pulasitiki zophimba zipewa ndi zoyala zimateteza mitu, mfundo, ndi mafupa.

Malo azachipatala

Mapulasitiki akhala akugwiritsidwa ntchito kwambiri popanga zida ndi zida zamankhwala monga magolovesi opangira opaleshoni, ma syringe, zolembera za insulin, machubu a IV, ma catheters, ma inflatable splints, matumba amagazi, ma chubu, makina a dialysis, ma valve amtima, miyendo yokumba, ndi kuvala mabala, pakati pawo. ena.

Ubwino wa Pulasitiki

• Zowona za Plastics
• Bakelite, pulasitiki yoyamba yopangidwa kwathunthu, idapangidwa mu 1907 ndi Leo Baekeland.Kuphatikiza apo, adapanga mawu akuti "pulasitiki".
• Mawu akuti “pulasitiki” amachokera ku mawu achigiriki akuti plastikos, omwe amatanthauza “wokhoza kuumbika kapena kuumbidwa.”
• Kupaka kumatengera pafupifupi gawo limodzi mwa magawo atatu a mapulasitiki onse opangidwa.Gawo limodzi mwa magawo atatu a dangalo limaperekedwa ku siding ndi mapaipi.
• Nthawi zambiri, mapulasitiki oyera sasungunuka m'madzi komanso opanda poizoni.Zowonjezera zambiri mu mapulasitiki, komabe, ndizowopsa ndipo zimatha kulowa m'malo.Phthalates ndi chitsanzo cha chowonjezera chapoizoni.Ma polima opanda poizoni akatenthedwa, amatha kusanduka mankhwala.
• Mafunso Omwe Amafunsidwa Kawirikawiri pa Kugwiritsa Ntchito Pulasitiki
• Kodi ubwino ndi zovuta za pulasitiki ndi ziti?
• Ubwino ndi zovuta za pulasitiki ndi izi:

Ubwino:

Pulasitiki ndi yosinthika komanso yotsika mtengo kuposa zitsulo.
Pulasitiki ndi yolimba kwambiri ndipo imatha kukhala kwa nthawi yayitali.
Kupanga pulasitiki kumathamanga kwambiri kuposa kupanga zitsulo.

Zovuta:

• Kuwola kwachilengedwe kwa mapulasitiki kumatenga zaka 400 mpaka 1000, ndipo ndi mitundu yochepa chabe ya mapulasitiki yomwe imatha kuwonongeka.
• Zinthu zapulasitiki zimawononga mathithi amadzi monga nyanja, nyanja, ndi nyanja, kupha nyama za m’madzi.
• Tsiku ndi tsiku, nyama zambiri zimadya zinthu zapulasitiki ndipo zimafa.
• Kupanga pulasitiki ndi kukonzanso zinthu kumatulutsa mpweya woipa ndi zotsalira zomwe zimawononga mpweya, madzi, ndi nthaka.
• Kodi pulasitiki yogwiritsidwa ntchito kwambiri ndi kuti?
• Chaka chilichonse, matani opitilira 70 miliyoni a thermoplastics amagwiritsidwa ntchito munsalu, makamaka pazovala ndi kapeti.

Kodi pulasitiki imagwira ntchito yanji pazachuma?

Pulasitiki ili ndi maubwino ambiri achindunji azachuma ndipo imatha kuthandizira kugwiritsa ntchito bwino zinthu.Imachepetsa kuwononga chakudya pokulitsa moyo wa alumali wa chakudya, ndipo kupepuka kwake kumachepetsa kugwiritsa ntchito mafuta ponyamula katundu.

Chifukwa chiyani tiyenera kukhala kutali ndi pulasitiki?

Pulasitiki iyenera kupewedwa chifukwa ndi yosawonongeka.Zimatenga zaka zingapo kuti ziwole zitalowetsedwa m'chilengedwe.Mapulasitiki amawononga chilengedwe.
