Chombo chokhazikika chimawoneka ngati gridi kapena lattice. Amapangidwa kuchokera kuzinthu zosalekeza za filament (zingwe).
Pofuna kusunga ulusi pamalo omwe mukufuna kumanja ndikofunikira kuti mugwirizane nawo
ulusi pamodzi. Mosiyana ndi zopangidwa zopangidwa ndi kukhazikika kwa ulusi wa warp ndi weft mu
zolakwa anaika ayenera kuchitidwa ndi chemical bonding. ulusi wa ulusi amangoyalidwa pansi
Izi zimatheka kudzera mukupanga.
Mlandu wopangidwaimapangidwa m'njira zitatu zofunika:
CHOCHITA 1: Mapepala a ulusi wa Warp amadyetsedwa kuchokera kumitengo yamagulu kapena mwachindunji kuchokera ku creel.
CHOCHITA CHACHIWIRI: Chida chozungulira chapadera, kapena turbine, imayala ulusi wopingasa pa liwiro lalikulu
kapena pakati pa mapepala opindika. The scrim nthawi yomweyo impregnated ndi zomatira dongosolo kuonetsetsa kukonza kwa makina- ndi ulusi njira mtanda.
CHOCHITA CHACHITATU: Chophimbacho chimawumitsidwa, kutenthedwa ndi kutenthedwa pa chubu
Kusiyana kwa Ma Scrims Opangidwa ndi Wolukidwa:
Zodziwika za Laid Scrims yathu:
| M'lifupi: | 500 mpaka 2500 mm | Kutalika kwa Roll: | Mpaka 50 000 m | Mtundu wa Ulusi: | Galasi, polyester, carbon | ||||||||
| Zomangamanga: | Square, njira zitatu | Mitundu: | Kuyambira 0.8 ulusi/cm mpaka 3 ulusi/cm | Kumanga: | PVOH, PVC, Acrylic, makonda | ||||||||
Ubwino waAnaika Scrims:
Nthawi zambirianaika scrimsndi pafupifupi 20 - 40 % zoonda kuposa zopangidwa kuchokera ku ulusi womwewo komanso zomangidwa mofanana.
Miyezo yambiri yaku Europe imafuna kuti padenga padenga pakhale kuphimba kwazinthu zochepera mbali zonse za scrim.Zowonongekakuthandizira kupanga zinthu zowonda popanda kuvomereza kutsika kwaukadaulo. Ndizotheka kupulumutsa zoposa 20% yazinthu zopangira monga PVC kapena PO.
Ndi olakwa okha omwe amalola kupanga kansalu kakang'ono kocheperako kocheperako katatu (1.2 mm) komwe kumagwiritsidwa ntchito ku Central Europe. Nsalu sizingagwiritsidwe ntchito popangira denga locheperapo kuposa 1.5 mm.
Kapangidwe ka aanaika scrimsichimawonekera kwenikweni m'chimake chomaliza kusiyana ndi mapangidwe a zipangizo zolukidwa. Izi zimapangitsa kuti pakhale malo osalala komanso ochulukirapo a chinthu chomaliza.
Kutsetsereka kwa zinthu zomaliza zomwe zili ndi ma scrims oyika zimalola kuwotcherera kapena kumata zigawo za zinthu zomaliza mosavuta komanso mokhazikika wina ndi mnzake.

Ngakhale zinthu zolukidwa zitha kuperekedwa ndi loomstate, aanaika scrimadzapatsidwa pathupi nthawi zonse. Chifukwa cha ichi tili ndi chidziwitso chochulukirapo ponena za zomwe binder ingakhale yoyenera kuzinthu zosiyanasiyana. Kusankha zomatira zolondola kumatha kukulitsa kulumikizana kwaanaika scrimndi chomaliza kwambiri.
Mfundo yakuti pamwamba ndi pansi zimalowa mkatianaika scrimsnthawi zonse adzakhala mbali imodzi ya ulusi wokhotakhota zimatsimikizira kuti ulusi wa warp nthawi zonse umakhala wovuta. Chifukwa chake mphamvu zolimba mu njira ya warp zidzatengedwa nthawi yomweyo. Chifukwa cha izi,anaika scrimsnthawi zambiri zimasonyeza kuchepetsedwa kwambiri elongation.Pamene laminating scrim pakati pa zigawo ziwiri za filimu kapena zipangizo zina, zomatira zochepa zidzafunika ndipo kugwirizana kwa laminate kudzakhala bwino.Kupanga scrims nthawi zonse kumafuna kuyanika kwa kutentha. Izi zimabweretsa kutsika kwa poliyesitala ndi ulusi wina wa thermoplastic zomwe zimathandizira kwambiri chithandizo chamakasitomala.
Zomangamanga zaAnaika Scrims:
Nkhondo imodzi
Uwu ndiye mapangidwe odziwika bwino a scrim. Ulusi woyamba wa warp* pansi pa ulusi wa weft** umatsatiridwa ndi ulusi wopingasa pamwamba pa ulusi wokhotakhota. Chitsanzochi chimabwerezedwa m'lifupi lonse. Nthawi zambiri mipata pakati pa ulusi imakhala yokhazikika m'lifupi mwake. Pa mphambano ulusi uwiri udzakumana.
* warp = ulusi wonse wolunjika pamakina
** weft = ulusi wonse wodutsa njira
Kuwombera kawiri
Ulusi wa pamwamba ndi wapansi umakhala wokhazikika umodzi pa inzake kotero kuti ulusi wokhotakhota uzikhala wokhazikika pakati pa ulusi wapamwamba ndi wapansi. Pa mphambano ulusi utatu udzakumana nthawi zonse.
Sungani ma laminates osawongoka
Scrim (imodzi kapena iwiri yopingasa) imayikidwa pansalu (yopangidwa kuchokera ku galasi, poliyesitala kapena ulusi wina). N'zotheka kupanga laminates ndi nonwovens kulemera kuchokera 0,44 mpaka 5.92 oz./sq.yd.
