Menene kayan samfuran filastik?

Abubuwan filastik galibi sun kasu kashi biyu na thermoplastic da thermosetting, mai zuwa shine cikakken gabatarwar, Ina fatan in taimaka.

1. Thermoplastic

Thermoplastics, kuma aka sani da resin thermoplastic, sune babban nau'in robobi.An yi su da kayan aikin polymer na roba waɗanda zasu iya gudana zuwa juna ta hanyar narkewa da zafi kuma suna iya sake warkewa.Waɗannan kayan yawanci suna da babban nauyin kwayoyin halitta kuma suna da tsarin sarkar kwayoyin mai maimaitawa.Thermoplastics za a iya sarrafa ta allura gyare-gyare, extrusion, busa gyare-gyare, calendering da sauran matakai don yin sassa da samfurori na daban-daban siffofi da kuma girma dabam.

(1) Polyethylene (PE): PE yana ɗaya daga cikin robobi na yau da kullun, ana amfani da su sosai a cikin marufi, bututu, insulators na waya da sauran dalilai.Dangane da tsarin kwayoyin halitta da yawa, PE za a iya raba shi zuwa babban yawa polyethylene (HDPE), ƙananan polyethylene (LDPE) da ƙananan ƙananan polyethylene na layi (LLDPE).

Polypropylene (PP): PP kuma filastik ne na kowa, wanda aka saba amfani dashi a cikin kwantena, kwalabe, da na'urorin likitanci.PP filasta ce ta Semi-crystalline, don haka ya fi PE tauri kuma ya fi gaskiya.

(3) Polyvinyl chloride (PVC): PVC na ɗaya daga cikin mafi girman samar da robobi a duniya, ana amfani da su sosai a cikin kayan gini, insulators na waya, marufi da na'urorin likitanci da sauran fannoni.PVC na iya zama mai launi kuma yana da tsayayya ga yawancin sinadarai.

(4) Polystyrene (PS): Ana amfani da PS don yin nauyi, kayan marufi na gaskiya, kamar kwantena abinci da akwatunan ajiya.Hakanan ana amfani da PS don yin kumfa, kamar kumfa EPS.

Acrylonitrile-butadiene-styrene copolymer (ABS) : ABS wani abu ne mai tauri, filastik mai jurewa da tasiri wanda aka saba amfani dashi don yin hannayen kayan aiki, gidaje na lantarki, da sassan mota.

(6) Wasu: Bugu da ƙari, akwai nau'ikan thermoplastics da yawa, kamar polyamide (PA), polycarbonate (PC), polyformaldehyde (POM), polytetrafluoroethylene (PTFE) da sauransu.

2, roba mai zafi

Robobi na thermosetting aji ne na musamman na robobi, daban da na thermoplastics.Wadannan kayan ba sa laushi kuma suna gudana lokacin da zafi, amma ana warkar da su ta hanyar zafi.Robobi masu zafi suna da ƙarfi da ƙarfi sosai kuma sun dace da aikace-aikacen da ke buƙatar ƙarfin ƙarfi da ƙarfi.

Epoxy resin (EP): Epoxy resin robobi ne mai tsananin zafi da ake amfani da shi a cikin gine-gine, kayan lantarki da masana'antar kera motoci.Epoxy resins na iya mayar da martani ta hanyar sinadarai tare da wasu kayan don samar da manne da sutura masu ƙarfi.

(2) Polyimide (PI): Polyimide filastik ne mai tsananin zafi wanda zai iya kula da kaddarorinsa a yanayin zafi.Ana amfani dashi ko'ina a cikin sararin samaniya, lantarki da masana'antar kera motoci don kera abubuwan da ke jure yanayin zafi da sutura.

(3) Wasu: Bugu da ƙari, akwai nau'ikan robobi na thermosetting da yawa, kamar resin phenolic, resin furan, polyester mara kyau da sauransu.
