Gilashin fiber yana da fa'idodi iri-iri kamar ƙarfin ƙarfi mai ƙarfi, nauyi mai sauƙi, juriya na lalata, juriya mai zafi, da kyakkyawan aikin rufin lantarki, wanda ya sa ya zama ɗayan abubuwan haɗaɗɗun da aka saba amfani da su.A sa'i daya kuma, kasar Sin ita ce kan gaba wajen samar da gilashin fiberglass a duniya.
1) Menene fiberglass?
Gilashin fiber abu ne na inorganic wanda ba na ƙarfe ba tare da kyakkyawan aiki.Ma'adinai ne na halitta da aka yi da silica, tare da takamaiman kayan ma'adinai na oxide na musamman da aka ƙara.Bayan an haɗe shi daidai gwargwado, sai ya narke a babban zafin jiki, kuma narkakkar ruwan gilashin yana fita ta cikin bututun ruwa.Ƙarƙashin ƙarfin juzu'i mai girma, yana shimfiɗawa kuma yana sanyaya cikin sauri kuma yana ƙarfafa shi cikin filaye masu ci gaba da kyau sosai.
Diamita na fiber monofilament na gilashin ya fito daga ƴan microns zuwa sama da microns ashirin, daidai da 1/20-1/5 na gashi, kuma kowane dam ɗin zaruruwa ya ƙunshi ɗaruruwa ko ma dubban monofilaments.
Abubuwan asali na fiber gilashi: Bayyanar sifa ce mai santsi mai santsi tare da cikakken sashin giciye na madauwari, kuma sashin madauwari yana da ƙarfin ɗaukar nauyi mai ƙarfi;Gas da ruwa suna da ƙarancin juriya ga wucewa, amma shimfidar wuri mai santsi yana rage haɗin kai na zaruruwa, wanda ba shi da amfani don haɗawa da resin;Yawan yawa shine gabaɗaya tsakanin 2.50 da 2.70 g/cm3, galibi ya danganta da abun da gilashin;Ƙarfin ƙarfi ya fi sauran fiber na halitta da filaye na roba;Gaggawa kayan suna da ƙananan elongation a karya;Kyakkyawan ruwa da juriya na acid, amma rashin juriya na alkali.
2) Gilashin fiber rarrabuwa
By tsawon rarrabuwa, shi za a iya raba zuwa ci gaba da gilashin fiber, short gilashin fiber (kafafi tsawon gilashin fiber), da kuma dogon gilashin fiber (LFT).
Fiber gilashin ci gaba a halin yanzu shine fiber gilashin da aka fi amfani da shi a cikin kasar Sin, wanda galibi ana kiransa "fiber dogo".Wakilan masana'antun sune Jushi, Dutsen Taishan, Xngwang, da dai sauransu.
Kafaffen fiber gilashin filaye ana kiransa da "gajeren fiber", wanda gabaɗaya ana amfani da shi ta hanyar gyare-gyaren gyare-gyare na ƙasashen waje da wasu kamfanoni na cikin gida.Wakilan masana'antun sune PPG, OCF da CPIC na gida, da ƙaramin adadin Jushi Dutsen Taishan.
LFT ya bayyana a kasar Sin a cikin 'yan shekarun nan, tare da masana'antun wakilai ciki har da PPG, CPIC, da Jushi.A halin yanzu, kamfanonin cikin gida irin su Jinfa, Shanghai Nayan, Suzhou Hechang, Jieshijie, Zhongguang Nukiliya Juner, Nanjing Julong, Shanghai Pulit, Hefei Huitong, Changsha Zhengming, da Rizhisheng duk suna samar da yawan jama'a.
Dangane da abun ciki na alkali, ana iya raba shi zuwa alkali kyauta, ƙananan matsakaici, kuma yawanci ana gyara shi da ƙarfafa shi da alkali kyauta, watau E-glass fiber.A kasar Sin, ana amfani da fiber E-glass gabaɗaya don gyarawa.
3) Aikace-aikace
Dangane da amfani da samfur, an raba asali zuwa nau'i hudu: kayan ƙarfafa don robobi na thermosetting, kayan ƙarfafa fiber gilashi don thermoplastics, kayan ƙarfafa gypsum siminti, da kayan yadi na fiber gilashi.Daga cikin su, kayan da aka ƙarfafa suna lissafin 70-75%, kuma kayan fiber na fiber gilashi suna lissafin 25-30%.Daga hangen nesa na buƙatun ƙasa, abubuwan more rayuwa sun kai kusan 38% (ciki har da bututun mai, lalata ruwan teku, dumama gida da hana ruwa, kiyaye ruwa, da sauransu), jigilar kayayyaki kusan 27-28% (yankin ruwa, motoci, jirgin ƙasa mai sauri, da dai sauransu). da dai sauransu), kuma na'urorin lantarki sun kai kusan kashi 17%.
