Chidule chachidule cha fiber glass

Chingwe chagalasi chinapangidwa mu 1938 ndi kampani ya ku America;Pa Nkhondo Yachiwiri Yapadziko Lonse m'zaka za m'ma 1940, zida zamagalasi zowonjezeredwa zidayamba kugwiritsidwa ntchito m'makampani ankhondo (zigawo za akasinja, kanyumba ka ndege, zipolopolo za zida, ma vests oteteza zipolopolo, ndi zina zambiri);Kenako, ndi mosalekeza kusintha kwa ntchito chuma, kuchepa kwa mtengo kupanga ndi chitukuko cha kunsi mtsinje gulu luso zipangizo, ntchito galasi CHIKWANGWANI wakhala kukodzedwa kumunda wamba.ntchito zake kumunsi mtsinje kuphimba minda ya zomangamanga, njanji zoyendera, petrochemical, galimoto kupanga, Azamlengalenga, mphepo mphamvu m'badwo, zipangizo zamagetsi, chilengedwe uinjiniya, uinjiniya m'madzi, etc., kukhala m'badwo watsopano wa zipangizo gulu m'malo zipangizo chikhalidwe monga zitsulo, nkhuni, mwala, etc, Ndi dziko njira akutuluka makampani, amene ali ndi tanthauzo lalikulu kwa chitukuko cha dziko, kusintha ndi kukweza.

Kutengera momwe msika wapadziko lonse lapansi umakhalira, mphamvu yopanga magalasi yapachaka ya opanga magalasi akuluakulu asanu ndi limodzi ku China, Jushi, Taishan Glass Fiber, Chongqing International Composite, Owens Corning (OC), NEG ndi JM adawerengera zopitilira 75. % ya mphamvu zonse zopangira magalasi padziko lonse lapansi, komanso mphamvu yopanga magalasi yapachaka ya opanga magalasi akuluakulu atatu ku China amapitilira 70% ya mphamvu yopanga magalasi apanyumba.Pankhani ya zotuluka m'nyumba, kuchuluka kwa zomwe amapanga mumakampani opanga magalasi ndizokwera.Mu 2020, gawo la CR3 ndi CR5 mumakampani opanga magalasi lidzafika 72% ndi 83% motsatana.

Kuphatikiza pa zimphona zazikulu zitatu zamagalasi za China Jushi, Taishan Fiberglass ndi International Composite, pali opanga magalasi apamwamba kwambiri pamsika, kuphatikiza Shandong Fiberglass, Sichuan Weibo, Zhengwei New Materials, Henan Guangyuan, Changhai Co., Ltd.
