Ruwan tabarau na kayan aiki, samfuran gani, na'urorin lantarki, kayan aikin likitanci, samfuran gaskiya, kayan ado, ruwan tabarau na rana, hakoran haƙora, allunan talla, fatunan agogo, fitilolin mota, gilashin iska, da sauransu.
3. Tsarin halaye na PMMA
Abubuwan aiki na PMMA suna da tsauri. Yana da matukar damuwa ga danshi da zafin jiki. Dole ne a bushe sosai kafin a sarrafa shi. Narke danko yana da girma sosai, don haka yana buƙatar gyara shi a yanayin zafi mafi girma (219 ~ 240 ℃) da matsa lamba. A mold zafin jiki ne tsakanin 65 ~ 80 ℃ ne mafi alhẽri. Tsarin zafin jiki na PMMA ba shi da kyau sosai. Za a lalata shi da babban zafin jiki ko kuma zama a cikin zafin jiki mafi girma na dogon lokaci. Gudun dunƙule bai kamata ya yi girma ba (kimanin 60rpm), saboda yana da sauƙin faruwa a cikin sassan PMMA masu kauri. Al'amarin ''rashin banza'' yana buƙatar manyan ƙofofi da "zazzaɓin kayan abu mai girma, yanayin zafi mai girma, saurin jinkirin" yanayin allura don aiwatarwa.
4. Menene acrylic (PMMA)?
Acrylic (PMMA) fili ne, robobi mai wuyar da ake amfani da shi a wurin gilashi a cikin samfura kamar tagogi masu rugujewa, alamu masu haske, fitillun sama da kwalin jirgin sama. PMMA na cikin muhimmin iyali na resin acrylic. Sunan sinadarai na acrylic shine polymethyl methacrylate (PMMA), wanda shine resin roba polymerized daga methyl methacrylate.
Polymethylmethacrylate (PMMA) kuma ana kiransa acrylic, gilashin acrylic, kuma ana samun su a ƙarƙashin sunayen kasuwanci da samfuran kamar Crylux, Plexiglas, Acrylite, Perclax, Astariglas, Lucite, da Perspex, da sauransu.

Idan an goge, zaku iya cire tarkace daga saman kuma ku taimaka kiyaye amincin sa.
6. Menene nau'ikan acrylic daban-daban?
Manyan nau'ikan filastik nau'ikan acrylic guda biyu sune simintin acrylic da acrylic extruded. Cast acrylic ya fi tsada don samarwa amma yana da mafi kyawun ƙarfi, dorewa, tsabta, kewayon zafin jiki da kwanciyar hankali fiye da acrylic extruded. Cast acrylic yana ba da kyakkyawan juriya da juriya na sinadarai, kuma yana da sauƙin launi da siffa yayin aikin masana'anta. Cast acrylic kuma ana samunsa cikin kauri iri-iri. Extruded acrylic ya fi tattalin arziki fiye da simintin simintin gyare-gyare kuma yana ba da daidaito, acrylic mai aiki fiye da simintin simintin gyare-gyare (a kashe ƙarancin ƙarfi). Extruded acrylic yana da sauƙin sarrafawa da na'ura, yana mai da shi kyakkyawan madadin ga zanen gilashi a aikace-aikace.
7. Me yasa ake amfani da acrylic sosai?
Ana amfani da acrylic sau da yawa saboda yana da halaye masu amfani iri ɗaya kamar gilashi, amma ba tare da al'amurra ba. Gilashin acrylic yana da kyawawan kaddarorin gani kuma yana da fihirisar refractive iri ɗaya kamar gilashin a cikin ƙasa mai ƙarfi. Saboda kaddarorin da ke da kariyarsa, masu zanen kaya na iya amfani da acrylics a wuraren da gilashin zai yi hatsari sosai ko kuma ba zai yi kasa ba (kamar ingin ruwa, tagogin jirgin sama, da sauransu). Misali, nau'in gilashin da aka fi sani da bulletproof shine yanki mai kauri 1/4-inch na acrylic, wanda ake kira da ƙarfi acrylic. Acrylic kuma yana aiki da kyau a cikin gyare-gyaren allura kuma ana iya samuwa a kusan kowace siffa da mai yin gyare-gyare zai iya ƙirƙirar. Ƙarfin gilashin acrylic haɗe tare da sauƙin sarrafawa da machining ya sa ya zama kayan aiki mai kyau, wanda ya bayyana dalilin da yasa ake amfani da shi sosai a cikin masana'antun masu amfani da kasuwanci.
