Matsenga ngati inu - fiberglass!

Chakumapeto kwa zaka za m'ma 1920, panthawi ya kupsinjika maganizo kwakukulu ku United States, boma linapereka Lamulo lodabwitsa: kuletsa. Chiletsocho chinatenga zaka 14, ndipo opanga mabotolo a vinyo anali m’mavuto. Kampani ya Owens Illinois inali yaikulu kwambiri yopanga mabotolo agalasi ku United States panthawiyo. Imatha kungowona ng'anjo zagalasi zikuzima. Panthawiyi, munthu wolemekezeka, wopha masewera, adadutsa pafupi ndi ng'anjo ya galasi ndipo adapeza kuti galasi lamadzimadzi lomwe linatayika linawomberedwa mu mawonekedwe a fiber. Masewera akuwoneka ngati Newton adagundidwa pamutu ndi apulo, ndigalasi ulusiwakhala pa siteji ya mbiri kuyambira pamenepo.
Patatha chaka chimodzi, Nkhondo Yachiwiri Yapadziko Lonse inayambika, ndipo zipangizo wamba zinali zochepa. Kuti akwaniritse zosowa za kukonzekera nkhondo yankhondo, ulusi wagalasi udalowa m'malo.
Anthu adapeza pang'onopang'ono kuti chinthu chaching'onochi chili ndi ubwino wambiri - kulemera kochepa, mphamvu zambiri, kutsekemera kwabwino, kuteteza kutentha ndi kutentha. Chifukwa chake, akasinja, ndege, zida, zovala zotchingira zipolopolo ndi zina zonse zimagwiritsa ntchito ulusi wagalasi.
Galasi CHIKWANGWANIndi inorganic watsopanozinthu zopanda zitsulo, yomwe imapangidwa kuchokera ku mchere wachilengedwe monga kaolin, pyrophyllite, mchenga wa quartz ndi miyala yamchere kudzera m'njira zingapo monga kusungunuka kwa kutentha kwambiri, kujambula kwa waya ndi kupiringa motsatira ndondomeko inayake. Kutalika kwake kwa monofilament kuli pakati pa ma microns angapo ndi ma microns oposa 20, omwe ndi ofanana ndi 1 / 20-1 / 5 ya ulusi wa tsitsi. Mtolo uliwonse wa fiber precursor umapangidwa ndi mazana kapena masauzande a monofilaments.

China galasi CHIKWANGWANI makampani ananyamuka mu 1958. Patapita zaka 60 chitukuko, pamaso pa kusintha ndi kutsegula, makamaka anatumikira chitetezo dziko ndi makampani asilikali, ndiyeno anatembenukira kwa ntchito boma, ndipo akwaniritsa chitukuko mofulumira.
