Fiberglass ndi zinthu zopanda zitsulo zomwe zimatha kulowa m'malo mwachitsulo, ndikuchita bwino kwambiri, ndipo zimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana azachuma cha dziko, zomwe zida zamagetsi, zoyendera ndi zomanga ndizo ntchito zazikulu zitatu.Ndi chiyembekezo chabwino cha chitukuko, makampani akuluakulu a fiberglass akuyang'ana kwambiri magwiridwe antchito komanso kukhathamiritsa kwa fiberglass.

1. Tanthauzo la fiberglass
Fiberglass ndi njira ina yopangira zitsulo komanso magwiridwe antchito abwino kwambiri azinthu zopanda zitsulo, ndi mchere wachilengedwe wokhala ndi silika monga chopangira chachikulu, onjezerani zida zachitsulo za oxide mineral.Kukonzekera kwake kumasungunuka pa kutentha kwakukulu, kukokedwa pansi pa mphamvu yothamanga kwambiri yokoka kumalo osungunuka a galasi lotambasulidwa kukhala ulusi.
Fiberglass monofilament m'mimba mwake kuchokera ku ma microns angapo kupita ku ma microns oposa makumi awiri, ofanana ndi tsitsi la 1 / 20-1 / 5, kusalungama kwa zojambulajambula ndi mazana kapena masauzande a monofilament.

2, Makhalidwe a fiberglass
Malo osungunuka a galasi fiber ndi 680 ℃, malo otentha ndi 1000 ℃, kachulukidwe ndi 2.4 ~ 2.7g / cm3.Kulimba kwamphamvu kokhazikika ndi 6.3 ~ 6.9g/d, kunyowa ndi 5.4 ~ 5.8g/d.
Wonjezerani kuuma ndi kuuma:kuwonjezeka kwa fiberglass kumatha kupititsa patsogolo mphamvu ndi kukhazikika kwa pulasitiki, koma kulimba kwa pulasitiki komweko kudzachepa.
Kulimba kwabwino, kosavuta kupunduka, kukana kukhudzidwa kwabwino:Njira yogwiritsira ntchito fiberglass, nthawi zina chifukwa cha kutambasula kapena mphamvu yokoka ndi kusinthika kwina, koma chifukwa cha kulimba kwake bwino, mumtundu wa mphamvu udzabwezeretsedwa ku choyambirira, kugwiritsa ntchito bwino kwambiri.

Kukana kutentha kwabwino:fiberglass ndi organic CHIKWANGWANI, matenthedwe madutsidwe ndi laling'ono kwambiri, sangachititse kuyaka, ndi kutentha kukana ndi zabwino.Nthawi zambiri amagwiritsidwa ntchito ngati chida chopanda moto popanga zinthu, zomwe zimatha kuchepetsa ngozi zambiri zachitetezo.
Kuyamwa chinyezi:Mayamwidwe amadzi a fiberglass ndi 1/20 ~ 1/10 ya ulusi wachilengedwe komanso wopangidwa.kuyamwa kwamadzi kumakhudzana ndi kapangidwe ka galasi, ndipo kuyamwa kwamadzi kwa ulusi wopanda alkali ndikocheperako, ndipo kuyamwa kwamadzi kwa ulusi wambiri wa alkali ndikokulirapo.
Kukhumudwa:Magalasi a fiberglass ndi olimba kwambiri kuposa ulusi wina, osamva kuvala komanso osavuta kuthyoka.Koma ulusi wa m'mimba mwake ukakhala wocheperako mpaka 3.8μm kapena kuchepera, ulusi ndi zinthu zake zimakhala zofewa bwino.
Kukaniza bwino kwa dzimbiri:Kukhazikika kwa mankhwala a fiberglass kumadalira mankhwala ake, chikhalidwe cha sing'anga, kutentha ndi kuthamanga, etc.. Fiberglass ili ndi kukana bwino kwa mankhwala owononga monga ma acid ndi alkalis, imakhala yosakhudzidwa ndi zosungunulira za organic, ndipo imakhala yokhazikika kwa anthu ambiri. mankhwala.
