Pet ndi chiyani? - kusanthula kodetsa kwa polyethylene terefite
Pet, kapena polyethylene terephthalate, ndi nkhani yogwiritsidwa ntchito kwambiri polima. Munkhaniyi, tikambirana mwachidule tanthauzo la Peter, magwiridwe ake ogwiritsa ntchito, njira zake zopangira ndi zabwino zake, kuti mupeze owerenga momvetsetsa za chiweto monga zinthu zofunika kwambiri.
Tanthauzo ndi zofunikira za chiweto
Pet ndi chiyani? Mankhwalawa, pet ndi polictostic poliction yopangidwa ndi polymesiyation ya terephthation acid ndi ethylene glycol.the mankhwala a ethylene glycol. Izi zimapangitsa kuti chiweto ichi chizipangitsa kuti chiweto ichi chizisankha mu zochitika zambiri zamagwiritsidwe ntchito, makamaka mu phukusi.
Madera akulu ogwiritsa ntchito
Pet imagwiritsidwa ntchito pamapulogalamu osiyanasiyana, kuyang'ana madera awiri akulu: Zipangizo zopangira ndi mapangidwe a fifiketi. Mu makampani ogulitsa, pet amagwiritsidwa ntchito popanga zinthu monga mabotolo apulasitiki, zokhala ndi mafilimu, zomwe zimagwiritsidwa ntchito ngati zotchinga zamagetsi, makamaka popanga mafakitale a polyester. Zovala zopangidwa ndi ulusi wopangidwa ndi ulusi wopangidwa ndi polyester ndizovuta, zosavuta, kusamba ndikusambitsa kuti ziume, ndikupangitsa kukhala koyenera kuvala kwatsiku ndi tsiku.
Njira Yopanga Ziweto
Kumvetsetsa zomwe chiweto chimafunikiranso kuyang'ana mozama pazinthu zake, zomwe zimachitika munjira ziwiri zazikulu: gawo limodzi (lolosera) ndi magawo awiri (EST Kusintha). Pazinthu zitatuzo, Terephthalic acid mwachindunji ndi Ethylene Glycol pamatenthedwe kwambiri ndi masitepe omwe amagwiritsidwa ntchito potsatira, kenako ndikugulitsa, kapena Kuumba jakisoni, kuti akonzekere mankhwala owumbidwa.
Ubwino ndi Kukhazikika Kwa Ziweto
Pet ndi chiyani? Kuchokera ku malingaliro okhazikika, maubwino a pet amadzibwezeretsanso; Zinthu zopangidwa ndi ziweto zimatha kubwezeretsedwanso kudzera pa Pyrolysis, kubwezeretsanso mankhwala ena komanso njira zina zochepetsera kuwonongeka kwa chilengedwe, ndipo mphamvu zopepuka ndi zopepukazi zimapatsanso mwayi pakuchepetsa mphamvu komanso zotengera. Makhalidwe awa amapanga chiweto chimodzi mwazinthu zobiriwira zobiriwira m'makampani amakono.
Mapeto
Kufotokozera mwachidule, kodi Pet? Ndi zinthu zolimbitsa thupi kwambiri ndi ntchito zosiyanasiyana. Kaya ndi zida zapaketi pamoyo watsiku ndi tsiku kapena kupanga zitsamba mu mafakitale, zokopa ziweto zili paliponse. Chifukwa chake, kumvetsetsa mwakuya kwa zomwe chiweto ndikofunikira kuti mumvetsetse zochitika zamakono zamankhwala.
