Kufotokozera Mokwanira za Mfundo Yopanga ndi Miyezo Yogwiritsa Ntchito ya
FiberglassWodulidwa Strand Mat
Mapangidwe a magalasi a ulusi wodulidwa wa strand mat amaphatikizapo kutenga magalasi a fiber rovings (ulusi wosapota ukhoza kugwiritsidwanso ntchito) ndi kuwadula mu ulusi wotalika 50mm pogwiritsa ntchito mpeni wodula. Zingwe zimenezi zimamwazikana n’kuzikonza mwadongosolo, n’kukhazikika pa lamba wonyamulira zitsulo zosapanga dzimbiri kuti apange mphasa. Njira zotsatila zimaphatikizapo kugwiritsa ntchito chomangira chomangira, chomwe chingakhale ngati zomatira zopopera kapena zomatira zothira madzi, kuti amangirire pamodzi zingwe zodulidwazo. The mphasa ndiye pansi mkulu-kutentha kuyanika ndi kukonzanso kupanga emulsion akanadulidwa chingwe mphasa kapena ufa akanadulidwa chingwe mphasa.

I. Zida Zopangira
Galasi yomwe imagwiritsidwa ntchito kwambiri popanga magalasi a fiberglass ndi mtundu wa calcium-aluminium borosilicate wokhala ndi zamchere zosakwana 1 peresenti. Nthawi zambiri amatchedwa "E-glass" chifukwa idapangidwa kuti ikhale yolumikizira magetsi.
Kupanga ulusi wamagalasi kumaphatikizapo kunyamula magalasi osungunuka kuchokera mung'anjo yosungunuka kudzera mu phula la platinamu lomwe lili ndi mabowo ang'onoang'ono, ndikulitambasulira kukhala ulusi wagalasi. Pazamalonda, ma filaments amakhala ndi mainchesi pakati pa 9 ndi 15 ma micrometer. Ulusi umenewu umakutidwa ndi kukula kwake asanasonkhanitsidwe kukhala ulusi. Ulusi wagalasi ndi wamphamvu kwambiri, wokhala ndi mphamvu zolimba kwambiri. Amasonyezanso kukana kwa mankhwala abwino, kukana chinyezi, mphamvu zabwino kwambiri zamagetsi, sizingawonongeke ndi tizilombo toyambitsa matenda, ndipo siziwotcha ndi malo osungunuka a 1500 ° C-kuwapangitsa kukhala oyenera kwambiri kuti agwiritsidwe ntchito muzinthu zophatikizika.
Ulusi wagalasi ukhoza kugwiritsidwa ntchito m’njira zosiyanasiyana: kudulidwa mu utali waufupi (“zingwe zodulidwa”), zosonkhanitsidwa m’zingwe zomangika momasuka (“rovings”), kapena kulukidwa munsalu zosiyanasiyana mwa kupota ndi kupeta ulusi wosalekeza. Ku UK, chinthu chomwe chimagwiritsidwa ntchito kwambiri pagalasi chimapangidwa ndi strand mat, chomwe chimapangidwa ndikudula magalasi ozungulira muutali pafupifupi 50mm ndikumangirira pamodzi pogwiritsa ntchito polyvinyl acetate kapena polyester binders, kuwapanga kukhala mphasa. Kulemera kwake kwa mphasa wodulidwa kumatha kusiyanasiyana kuchokera ku 100gsm mpaka 1200gsm ndipo ndizothandiza pakulimbitsa.
II. Binder Application Stage
Ulusi wagalasi umatengedwa kuchokera pagawo lokhazikika kupita ku lamba wotumizira, pomwe chomangira chimayikidwa. Gawo lokhazikitsira liyenera kukhala laukhondo komanso louma. Ntchito yomangira imachitika pogwiritsa ntchito zida ziwiri zomangira ufa ndi ma nozzles angapo opopera madzi.
Pa mphasa yodulidwa, kumbali zonse zakumwamba ndi zapansi, kupopera pang'ono kwa madzi a demineralized kumayikidwa. Gawo ili ndilofunika kuti chomangiracho chimamatire bwino. Ogwiritsira ntchito ufa wapadera amaonetsetsa kuti ufawo ugawidwe. Oscillators pakati pa ogwiritsira ntchito awiriwa amathandiza kusamutsa ufa kumunsi kwa mphasa.
III. Kumanga ndi Emulsion
Njira yotchinga yomwe imagwiritsidwa ntchito imatsimikizira kubalalitsidwa bwino kwa binder. Zomangira zowonjezera zimapezedwanso kudzera munjira yapadera yoyamwa.
Dongosololi limalola mpweya kunyamula zomangira zochulukirapo kuchokera pamphasa ndipo chomangiracho chimagawidwa mofanana, kuchotsa zomangira zochulukirapo. Mwachiwonekere, zonyansa zosefedwa mu binder zitha kugwiritsidwanso ntchito.
Chomangiracho chimasungidwa m'mitsuko mu chipinda chosanganikirana ndikunyamulidwa kuchokera m'miyendo yaying'ono pafupi ndi chomera cha mphasa kudzera m'mipope yocheperako.
Zida zapadera zimasunga mlingo wa thanki nthawi zonse. Zomanganso zobwezerezedwanso zimaperekedwanso ku thanki. Mapampu amanyamula zomatira kuchokera ku thanki kupita kumalo opangira zomatira.
IV. Kupanga
Glass fiber chopped strand mat ndi chinthu chosalukidwa chomwe chimapangidwa podula ulusi wautali kukhala 25-50mm utali, kuziyika mosintha pa ndege yopingasa, ndikuzigwirizanitsa pamodzi ndi chomangira choyenera. Pali mitundu iwiri ya zomangira: ufa ndi emulsion. Zomwe zimapangidwa ndi zinthu zophatikizika zimadalira kuphatikiza kwa filament diameter, kusankha binder, ndi kuchuluka kwake, makamaka kumatsimikiziridwa ndi mtundu wa mphasa womwe umagwiritsidwa ntchito komanso njira yopangira.
Zopangira zopangira ma strand mat odulidwa ndi makeke opanga magalasi opanga magalasi, koma ena amagwiritsanso ntchito ma rovings, mwanjira ina kuti asunge malo.
Pamtundu wa mat, ndikofunikira kukhala ndi mawonekedwe abwino odulira ulusi, magetsi otsika, komanso kugwiritsa ntchito ma binder ochepa.

VI. Chigawo cha Creel
Zoyimira zozungulira za creel zimayikidwa pa chimango chokhala ndi ma bobbins oyenerera. Popeza ma creel awa amakhala ndi makeke a ulusi, malo a creel ayenera kukhala m'chipinda choyendetsedwa ndi chinyezi chokhala ndi chinyezi cha 82-90%.
VII. Zida Zodulira
Ulusi umakokedwa kuchokera ku makeke oyendayenda, ndipo mpeni uliwonse wodula uli ndi zingwe zingapo zomwe zimadutsamo.
VIII. Kupanga Gawo
Mapangidwe a mphasa wodulidwa amaphatikizapo kugawa zingwe zodulidwazo mosiyanasiyana mu chipinda chopangiramo. Chida chilichonse chili ndi ma motors osinthika. Zida zodulira zimayendetsedwa paokha kuti zitsimikizire ngakhale kugawa kwa ulusi.
Mpweya womwe uli pansi pa lamba wotumizira umakokanso ulusi kuchokera pamwamba pa lambayo. Mpweya wotuluka umadutsa pa choyeretsa.
IX. Makulidwe a Glass Fiber Chopped Strand Mat Layer
Pazinthu zambiri zolimbitsa magalasi a fiberglass, mphasa wa magalasi odulidwa amaphatikizidwa, ndipo kuchuluka ndi njira yogwiritsira ntchito matimu odulidwa amasiyana malinga ndi zomwe zimapangidwa ndi ndondomeko. Makulidwe osanjikiza amadalira njira yopangira yofunikira!
Mwachitsanzo, popanga nsanja zozizirira za fiberglass, wosanjikiza umodzi umakutidwa ndi utomoni, wotsatiridwa ndi wosanjikiza umodzi wa mphasa woonda kapena 02 nsalu. Pakatikati, zigawo za 6-8 za nsalu za 04 zimayikidwa, ndipo chowonjezera chowonjezera cha mphasa woonda chimayikidwa pamwamba kuti chiphimbe zolumikizira zamkati. Pankhaniyi, zigawo ziwiri zokha za mphasa woonda zimagwiritsidwa ntchito. Momwemonso, popanga madenga agalimoto, zida zosiyanasiyana monga nsalu zoluka, nsalu zosalukidwa, pulasitiki ya PP, mphasa woonda, ndi thovu zimaphatikizidwa m'magawo, okhala ndi mphasa zoonda zomwe zimagwiritsidwa ntchito mu zigawo ziwiri zokha panthawi yopanga. Ngakhale kupanga Honda galimoto denga, ndondomeko ndi ofanana. Choncho, kuchuluka kwa mphasa wodulidwa wodulidwa wogwiritsidwa ntchito mu fiberglass amasiyana malinga ndi ndondomekoyi, ndipo njira zina sizingafunikire kugwiritsidwa ntchito pamene zina zimatero.
Ngati tani imodzi ya magalasi a fiberglass apangidwa pogwiritsa ntchito mphasa wodulidwa wodulidwa ndi utomoni, kulemera kwa mphasa wodulidwa kumakhala pafupifupi 30% ya kulemera kwake konse, komwe ndi 300Kg. M'mawu ena, utomoni wokhutira ndi 70%.
Kuchuluka kwa mphasa wodulidwa womwe umagwiritsidwa ntchito panjira yomweyo umatsimikiziridwa ndi kapangidwe ka wosanjikiza. Mapangidwe a masanjidwe amatengera zomwe zimafunikira pamakina, mawonekedwe azinthu, zofunika kumaliza pamwamba, ndi zina.
X. Miyezo Yogwiritsa Ntchito
Kugwiritsiridwa ntchito kwa magalasi opanda magalasi a alkali-free fiber chopped strand mat kukuchulukirachulukira ndipo kumaphatikizapo madera osiyanasiyana apamwamba monga magalimoto, nyanja, ndege, kupanga mphamvu za mphepo, ndi kupanga asilikali. Komabe, mwina simukudziwa zoyenera kuchita pa mphasa wagalasi wopanda alkali wopanda ulusi wodulidwa. Pansipa, tikuwonetsa zofunikira za muyezo wapadziko lonse lapansi wokhudzana ndi zinthu za alkali metal oxide, kupatuka kwa unit area mass, zoyaka, chinyezi, komanso kusweka kwamphamvu:
Alkali Metal Content
The alkali zitsulo okusayidi zili mu alkali-free galasi CHIKWANGWANI akanadulidwa strand mphasa sayenera kupitirira 0.8%.
Unit Area Misa
Zinthu Zoyaka
Pokhapokha ngati tafotokozedwa mwanjira ina, zinthu zoyaka moto ziyenera kukhala pakati pa 1.8% ndi 8.5%, ndi kupatuka kwakukulu kwa 2.0%.
Chinyezi
Kuchuluka kwa chinyezi pamphasa pogwiritsa ntchito zomatira ufa sayenera kupitirira 2.0%, ndi mphasa yogwiritsira ntchito emulsion zomatira, sayenera kupitirira 5.0%.
Mphamvu Yophwanya Mphamvu
Nthawi zambiri, mtundu wa mphasa wopanda magalasi wopanda mchere wa alkali wodulidwa umakwaniritsa zomwe zili pamwambazi kuti ziwoneke ngati zovomerezeka. Komabe, kutengera zomwe akufuna kugwiritsa ntchito, njira yopangirayo imatha kukhala ndi zofunika kwambiri pakulimba kwamphamvu komanso kupatuka kwa gawo lagawo. Chifukwa chake, ndikofunikira kuti ogwira ntchito athu adziwe bwino momwe amapangira zinthu zawo komanso zofunikira za ma strand mat odulidwa kuti ogulitsa athe kupanga moyenera. ”
