Zida Zoseweretsa Zamakono
"Vinyl", "resin", "PU resin", "PVC", "Polystone", ndikukhulupirira kuti abwenzi omwe ali ndi chidwi ndi zoseweretsa zamakono amvapo mawu awa.
izi ndi Ziyani? Kodi onse ndi pulasitiki? Kodi utomoni ndi wokwera mtengo komanso wapamwamba kuposa vinyl?
Aliyense amasokonezeka pa nkhani izi za zipangizo zamakono ndi zaluso.
Pali mitundu isanu ikuluikulu yamapulasitiki omwe amagwiritsidwa ntchito nthawi zonse: PE (Polyethylene), PP (Polypropylene), PVC (Polyvinyl chloride), PS (Polystyrene) ndi ABS (Acrylonitrile-butadiene-styrene Copolymer), PVC ndi ABS nthawi zambiri amagwiritsidwa ntchito zidole zamafashoni.
Ndipo tawona kuti ntchito za mlengi wina zimagwiritsa ntchito "resin" zakuthupi, ndipo ambiri mwa iwo ndi PU resin (Polyuracet), Polyurethane ndi chiyani?
PU utomoni (polyurethane) ndi organic polima pawiri, wotchedwa pulasitiki waukulu wachisanu ndi chimodzi.
Zithunzi za PVC
PVC imabwera m'njira ziwiri: yokhazikika komanso yosinthika. Mitundu yolimba m'moyo monga mapaipi amadzi, makhadi aku banki, ndi zina zambiri; zinthu zosinthika zimakhala zofewa komanso zotanuka powonjezera mapulasitiki, monga ma raincoats, mafilimu apulasitiki, zinthu zotha kufufuma, ndi zina zambiri.
PVC ndi vinilu zomwe zimagwiritsidwa ntchito pazithunzi zodziwika bwino za PVC zimapangidwa ndi PVC (polyvinyl chloride), koma njira zake ndi zosiyana. PVC nthawi zambiri imatanthawuza njira yopangira jekeseni, ndipo "vinyl" ndi njira yapadera yopanga PVC yomwe imaphatikiza madzi ndi "glue". (Pasta PVC solution) imakutidwa mofanana pakhoma lamkati la nkhungu kudzera mu kasinthasintha wa centrifugal.
ABS
ABS imapangidwa ndi Acrylonitrile (PAN), Butadiene (PB), ndi Styrene (PS) ndi copolymer ya zigawo zitatu, zomwe zimagwirizanitsa ubwino wa ntchito za zigawo zitatu. Ndi chinthu "cholimba, cholimba komanso chokhazikika" chokhala ndi zida zopezeka mosavuta, zotsika mtengo, zogwira ntchito bwino komanso zogwiritsidwa ntchito mosiyanasiyana. Ili ndi kutentha kwambiri komanso kuzizira kwambiri.
ABS ndiyosavuta kukonza. Iwo akhoza kupangidwa ndi njira zosiyanasiyana ndondomeko monga jekeseni, extrusion, ndi thermoforming; itha kukonzedwa ndi macheka, kubowola, kusefera, kugaya, etc.; imatha kulumikizidwa ndi zosungunulira organic monga chloroform; imathanso kupopera, utoto, electroplated, ndi mankhwala ena apamwamba.
M'makampani azoseweretsa, chitsanzo chodziwika kwambiri cha ntchito ya ABS ndi LEGO.
