Fiber Glass ili ndi maubwino osiyanasiyana monga kulimba kwamphamvu kwambiri, kulemera pang'ono, kukana dzimbiri, kukana kutentha kwambiri, komanso magwiridwe antchito abwino amagetsi, zomwe zimapangitsa kuti ikhale imodzi mwazinthu zophatikizika zomwe zimagwiritsidwa ntchito kwambiri.Pa nthawi yomweyo, China ndiyenso padziko lonse lapansi opanga magalasi a fiberglass.
1) fiberglass ndi chiyani?
Galasi CHIKWANGWANI ndi inorganic sanali zitsulo chuma ndi ntchito kwambiri.Ndi mchere wachilengedwe wopangidwa ndi silika, wokhala ndi zitsulo zachitsulo za oxide mineral zowonjezeredwa.Akasakanizidwa mofanana, amasungunuka pa kutentha kwakukulu, ndipo madzi agalasi osungunuka amatuluka kudzera mumphuno yotayikira.Pansi pa mphamvu yothamanga kwambiri, imatambasulidwa ndikukhazikika mwachangu ndikukhazikika kukhala ulusi wabwino kwambiri wopitilira.
The awiri a galasi CHIKWANGWANI monofilament ranges kuchokera ma microns ochepa mpaka ma microns makumi awiri, ofanana 1/20-1/5 wa tsitsi, ndipo aliyense mtolo wa ulusi wapangidwa ndi mazana kapena masauzande a monofilaments.
Zofunikira za ulusi wamagalasi: Mawonekedwe ake ndi mawonekedwe osalala a cylindrical okhala ndi gawo lonse lozungulira, ndipo gawo lozungulira lozungulira lili ndi mphamvu zonyamula katundu;Gasi ndi madzi zimakhala ndi kukana pang'ono kuti zidutse, koma malo osalala amachepetsa kugwirizana kwa ulusi, zomwe sizikugwirizana ndi kugwirizana ndi utomoni;Kachulukidwe nthawi zambiri amakhala pakati pa 2.50 ndi 2.70 g/cm3, makamaka kutengera kapangidwe ka galasi;Mphamvu zamakokedwe ndizokwera kuposa ulusi wina wachilengedwe ndi ulusi wopangira;Zida za Brittle zimakhala ndi elongation yotsika kwambiri panthawi yopuma;Madzi abwino ndi kukana kwa asidi, koma kusagwirizana kwa alkali.
2) Gulu lagalasi la fiber
Potengera kutalika kwa magalasi, imatha kugawidwa kukhala ulusi wagalasi wopitilira, ulusi wagalasi wamfupi (utali wokhazikika wagalasi), ndi ulusi wagalasi wautali (LFT).
Ulusi wagalasi wosalekeza ndizomwe zimagwiritsidwa ntchito kwambiri pagalasi ku China, zomwe zimatchedwa "utali wautali".Opanga oyimira ndi Jushi, Mount Taishan, Xingwang, etc.
Fixed glass fiber fibers nthawi zambiri amatchedwa "chingwe chachifupi", chomwe chimagwiritsidwa ntchito ndi zosintha zomwe zimathandizidwa ndi ndalama zakunja ndi mabizinesi ena apakhomo.Opanga oyimira ndi PPG, OCF ndi CPIC yapakhomo, ndi ochepa a Jushi Mount Taishan.
LFT yatulukira ku China m'zaka zaposachedwa, ndi opanga oyimira kuphatikiza PPG, CPIC, ndi Jushi.Pakadali pano, mabizinesi apakhomo monga Jinfa, Shanghai Nayan, Suzhou Hechang, Jieshijie, Zhongguang Nuclear Juner, Nanjing Julong, Shanghai Pulit, Hefei Huitong, Changsha Zhengming, ndi Rizhisheng onse amapanga zinthu zambiri.
Malinga ndi zomwe zili zitsulo zamchere, zitha kugawidwa m'malo amchere, otsika sing'anga okwera, ndipo nthawi zambiri amasinthidwa ndi kulimbikitsidwa ndi alkali wopanda, mwachitsanzo, E-glass fiber.Ku China, E-glass fiber nthawi zambiri imagwiritsidwa ntchito posintha.
3) Kugwiritsa ntchito
Malinga ndi kagwiritsidwe ntchito kazinthu, zimagawidwa m'magulu anayi: zida zomangirira zamapulasitiki a thermosetting, zida zolimbitsa magalasi zamagalasi a thermoplastics, zida zolimbikitsira simenti ya gypsum, ndi zida zamagalasi zamagalasi.Pakati pawo, zida zolimbitsidwa zimawerengera 70-75%, ndipo zida zamagalasi zopangira nsalu zimakhala 25-30%.Malinga ndi zomwe zikufunika kumunsi kwa mtsinje, zomangamanga zimakhala pafupifupi 38% (kuphatikiza mapaipi, kuchotsera madzi am'nyanja, kutentha kwa nyumba ndi kutsekereza madzi, kusunga madzi, ndi zina zotero), mayendedwe amawerengera pafupifupi 27-28% (ma yacht, magalimoto, njanji yothamanga kwambiri, etc.), ndipo zamagetsi zimakhala pafupifupi 17%.
