Checkered jira harina - twist roving plain jira, chinhu chakakosha base zvinhu zveruoko - namira FRP.Simba re gingham rinonyanya mu warp uye weft nzira yejira.Kune nguva dzinoda kusimba kwakakwira kana weft, inogona zvakare kurukwa kuita imwe-nzira gingham, iyo inogona kurongeka muwarp kana weft yakawanda twisting roving.
Zvinodiwa zvemhando yegingerbread ndezvizvi: ① Jira rakafanana, mupendero wakatwasuka, nzvimbo yacho yakati sandara uye yakamanikana, uye hapana gwara, fuzz, crease kana kuunyana;② Warp uye weft density, uremu hwenzvimbo, upamhi hwejira uye kureba kwemupumburu zvinosangana nechiyero;③ Kupeta pabepa rakasimba, kumonereka zvakanaka;④ Kukurumidza uye kwakanaka resin permeability;⑤ Iyo yakaoma uye yakanyorova mechanical simba remaraini akaitwa nemucheka anofanira kusangana nezvinodiwa.
Hunhu hwemusanganiswa wakaputirwa nemucheka weplaid hwakaderera interlaminar shear simba uye kusasimba kwekumanikidza uye kuneta simba.
Fiberglass yakanzwa pepa
(1) Cheka shinda inonzwa: cheka shinda yegirazi (dzimwe nguva isina kumonereka roving) kuita 50mm kureba, iparadzire zvisina tsarukano asi zvakaenzana pabhandi remambure, wobva waisa emulsion binder kana kumwaya poda binder, kupisa kupisa uye bond mumucheka wakachekwa wanzwa. .Cheka inonzwa inonyanya kushandiswa mukunamira kwemaoko, inoenderera mberi kugadzira ndiro uye kufa kudzvanya uye SMC maitiro.Zvinodiwa zvemhando yeshinda yakachekwa zvinonzwika seizvi: ① Hunhu hwenzvimbo hwakafanana pahupamhi hwegwara;②Iyo yakachekwa filament yakagoverwa zvakaenzana pane yakanzwa, hapana maburi makuru akaumbwa, uye binder yakagoverwa zvakaenzana.③ pakati nepakati yakaoma inonzwa simba;④ Yakanakisa resin kupinza uye kupinda.
(2) Inoramba ichinzwika mbishi: girazi sirika mbishi inoumbwa mukudhirowa kana sirika mbishi inoenderera yakatorwa kubva pachubhu yesirika mbishi inowaridzwa painoramba ichifamba mesh bhandi mumufananidzo 8, uye poda binder inonamirwa pamwechete.Iyo fiber yekuenderera mberi fiberglass fibril mat inoenderera, saka iyo yekusimbisa kwayo mhedzisiro pane inoumbwa zvinhu iri nani pane iyo yekucheka fiberglass mat.Inonyanya kushandiswa mukuita pultruding, RTM, bhegi rekumanikidza uye girazi rainzwa rakasimbiswa thermal plastiki (GMT).
(3) Surface inonzwa: Zvigadzirwa zveFRP zvinowanzoda kuumba rakapfuma resin layer, iyo inowanzoitwa nepakati alkali girazi pamusoro inonzwa.Nekuti rudzi urwu rwekunzwa rwakagadzirwa nepakati alkali girazi (C), inopa FRP makemikari kuramba, kunyanya acid kuramba.Panguva imwecheteyo, nekuti iyo inonzwa yakatetepa uye girazi fiber dhayamita idiki, inogona zvakare kutora yakawanda resin kuti igadzire resin yakapfuma layer, inovhara tsanga yegirazi fiber yakasimbiswa zvinhu (senge jira rejira), uye kutamba basa rekugadzirisa pamusoro.
4Staple faibha inodikamwa inonzwika inogadzirwa nekucheka girazi faibha roving kuita 50mm zvidimbu uye zvisina tsarukano kuzviisa pane substrate pre-yakaiswa pabhandi rekutakura.Zvino tsono dzine mabhabhu dzinoshandiswa kubaya mafiibhi akakosha musubstrate, ukuwo crochet ichikochekera mamwe mafiibhi kuti iite matatu-dimensional chimiro.Iyo yekutanga zvinhu inogona kunge iri girazi faibha kana imwe faibha yakatetepa jira, iyi mhando yetsono inonzwa ine fuzzy kunzwa.Kunyanya kushandiswa kwayo kunosanganisira kupisa kwekudzivirira zvinhu, kupisa lining material, sefa zvinhu, uye zvinogonawo kushandiswa mukugadzirwa kweFRP, asi simba reFRP rakaderera, chiyero chekushandisa chishoma.Imwe mhando yekuenderera mberi kwekutanga filament inodiwa inonzwa ndeye matatu-dimensional chimiro chekunzwa umo inoenderera girazi primary filament inokandwa zvisina tsarukano painoenderera mesh bhandi newaya yekukanda mudziyo uye inobairwa netsono ndiro.Rudzi urwu rwekunzwa runonyanya kushandiswa mukugadzirwa kwegirazi fiber yakasimbisa thermoplastic stampable sheets.
(5) yakasonwa yakanzwa: cheka girazi faibha kubva pa50mm kana kunyange 60cm kureba inogona kusonanidzwa mukucheka faibha kana refu fiber inonzwa nemuchina wekusona.Iyo yekutanga inogona kutsiva yechinyakare bhainda yakasungwa yakachekwa yakanzwika mune akati wandei mashandisiro, uye iyo yekupedzisira inogona kutsiva inoenderera mbishi fiber inonzwa kune imwe nhanho.Zvakanakira zvavo zvakajairika hapana binder, dzivisa kusvibiswa kwemaitiro ekugadzira, panguva imwechete, kupinza kwakanaka, kusunga kuita, mutengo wakaderera.
