Ulusi wagalasi uli ndi zinthu zabwino kwambiri ndipo umagwiritsidwa ntchito kwambiri m'magawo ambiri.Ndizinthu zopanda zitsulo zomwe zimatha kusintha zitsulo.Chifukwa cha chiyembekezo chake chachitukuko, makampani akuluakulu opangira magalasi akuyang'ana kwambiri kafukufuku wokhudza magwiridwe antchito apamwamba komanso kukhathamiritsa kwa ulusi wamagalasi.
1 Tanthauzo la ulusi wa galasi
Ulusi wagalasi ndi mtundu wazinthu zopanda zitsulo zomwe zimatha m'malo mwachitsulo ndipo zimakhala ndi ntchito yabwino kwambiri.Amakonzedwa pojambula galasi losungunuka kukhala ulusi pogwiritsa ntchito mphamvu yakunja.Ili ndi mawonekedwe amphamvu kwambiri, modulus yayikulu komanso elongation yotsika.Kutentha kwa kutentha ndi kupanikizika, kuwonjezereka kwa kutentha kwakukulu, malo osungunuka kwambiri, kutentha kwake kofewetsa kumatha kufika 550 ~ 750 ℃, kukhazikika kwa mankhwala abwino, osavuta kuwotcha, ali ndi makhalidwe abwino kwambiri monga kukana kwa dzimbiri, ndipo wakhala akugwiritsidwa ntchito kwambiri m'madera ambiri. .
2 Makhalidwe a galasi fiber
Malo osungunuka a galasi fiber ndi 680 ℃, malo otentha ndi 1000 ℃, ndipo kachulukidwe ndi 2.4 ~ 2.7g / cm3.Mphamvu yamakokedwe ndi 6.3 mpaka 6.9 g/d mumkhalidwe wokhazikika ndi 5.4 mpaka 5.8 g/d pakunyowa.Glass fiber ali ndi kukana kwabwino kwa kutentha komanso ndi zida zotchingira zapamwamba zokhala ndi zotchingira zabwino, zomwe ndizoyenera kupanga zotchingira zotenthetsera ndi zida zosawotcha.
3 Mapangidwe a galasi fiber
Galasi yomwe imagwiritsidwa ntchito popanga ulusi wagalasi ndi yosiyana ndi magalasi omwe amagwiritsidwa ntchito muzinthu zina zamagalasi.Galasi yomwe imagwiritsidwa ntchito popanga ulusi wagalasi imakhala ndi izi:
(1)E-glass,lomwe limadziwikanso kuti galasi lopanda alkali, ndi la galasi la borosilicate.Zina mwazinthu zomwe zimagwiritsidwa ntchito popanga ulusi wagalasi, magalasi opanda alkali ndi omwe amagwiritsidwa ntchito kwambiri.Galasi yopanda zamchere imakhala ndi kutchinjiriza kwabwino komanso makina, ndipo imagwiritsidwa ntchito makamaka popanga ulusi wagalasi wotsekereza komanso ulusi wamphamvu wagalasi, koma galasi lopanda zamchere sililimbana ndi dzimbiri la inorganic acid, kotero siliyenera kugwiritsidwa ntchito m'malo acidic. .Tili ndi e-glassfiberglass yozungulira, e-glassmagalasi opangidwa ndi fiberglass,ndi e-glassfiberglass mat.
(2)C-galasi, yomwe imadziwikanso kuti galasi lapakati lamchere.Poyerekeza ndi galasi lopanda mchere, lili ndi kukana kwamankhwala kwabwino komanso kuperewera kwamagetsi ndi makina.Kuonjezera diboron trichloride ku magalasi apakatikati a alkali kumatha kupangagalasi CHIKWANGWANI pamwamba mphasa,amene ali ndi makhalidwe a dzimbiri kukana.Ulusi wagalasi wopanda boron wopanda sing'anga-alkali amagwiritsidwa ntchito makamaka popanga nsalu zosefera ndi nsalu zokutira.
Fiberglass akanadulidwa strand mphasa
(3)Magalasi apamwamba kwambiri,monga momwe dzinalo likusonyezera, ulusi wagalasi wamphamvu kwambiri uli ndi mawonekedwe amphamvu kwambiri komanso modulus wapamwamba.Mphamvu yake yamagetsi ndi 2800MPa, yomwe ili pafupifupi 25% kuposa ya ulusi wagalasi wopanda alkali, ndipo modulus yake yotanuka ndi 86000MPa, yomwe ndi yokwera kuposa ya E-glass fiber.Kutulutsa kwa galasi lamphamvu kwambiri lagalasi sipamwamba, kuphatikizapo mphamvu zake zazikulu ndi modulus yapamwamba, choncho nthawi zambiri amagwiritsidwa ntchito m'magulu ankhondo, zamlengalenga ndi zamasewera ndi zina, ndipo sizigwiritsidwa ntchito kwambiri m'madera ena.
(4)AR galasi CHIKWANGWANI, womwe umadziwikanso kuti ulusi wagalasi wosamva alkali, ndi ulusi wachilengedwe.Ulusi wagalasi wosamva za alkali uli ndi kukana bwino kwa alkali ndipo umatha kukana dzimbiri la zinthu zamchere wambiri.Ili ndi zotanuka kwambiri modulus komanso kukana kwamphamvu, kulimba kwamphamvu komanso mphamvu yopindika.Lilinso ndi makhalidwe osayaka, kukana chisanu, kutentha ndi chinyezi kukana, kukana ming'alu, kusungunuka, pulasitiki yamphamvu komanso kuumba kosavuta.Nthiti zakuthupi magalasi CHIKWANGWANI analimbitsa konkire.
4 Kukonzekera kwa galasi ulusi
Njira yopangiragalasi fiberNthawi zambiri amasungunula zopangira, kenako ndikuchita chithandizo cha fiberizing.Ngati iti ikhale yofanana ndi mipira ya galasi kapena ndodo za fiberglass, chithandizo cha fiberglass sichingachitike mwachindunji.Pali njira zitatu za fibrillation zamagalasi ulusi:
Njira yojambulira: njira yayikulu ndi njira yojambulira nozzle ya filament, yotsatiridwa ndi njira yojambulira ndodo yamagalasi ndi njira yojambula yosungunuka;
Njira ya Centrifugal: ng'oma centrifugation, sitepe centrifugation ndi yopingasa porcelain chimbale centrifugation;
Njira yowuzira: njira yowuzira ndi kuwomba ndi nozzle.
Njira zingapo zomwe zili pamwambazi zitha kugwiritsidwanso ntchito kuphatikiza, monga kujambula-kuwomba ndi zina zotero.Post-processing imachitika pambuyo fiberizing.Kukonza pambuyo pakukonza ulusi wagalasi wansalu kumagawidwa m'njira ziwiri zazikulu:
(1) Pakupanga ulusi wagalasi, ulusi wagalasi wophatikizidwa musanakhote uyenera kukhala wocheperako, ndipo ulusi waufupiwo uyenera kupakidwa mafuta opaka mafuta asanasonkhanitsidwe ndikuwombedwa ndi mabowo.
(2) Kuchulukirachulukira, malinga ndi momwe magalasi amakhalira ndi lalifupigalasi fiber roving pali njira zotsatirazi:
①Njira zazifupi zopangira magalasi:
②Kukonza masitepe a galasi lokhazikika la fiber roving:
