Chigoba cholumikizidwa chimaoneka ngati gridi kapena latisi. Ndi nsalu yolimbitsa yotsika mtengo yopangidwa ndi ulusi wopitilira muyeso wopangidwa ndi maukonde otseguka. Njira yopangira chigoba cholumikizidwa imagwirizanitsa ulusi wosalukidwa pamodzi, ndikuwonjezera chigobacho ndi mawonekedwe apadera.
Kulimba kwambiri, Kusinthasintha, Mphamvu yokoka, Kuchepa pang'ono, Kutalikirana pang'ono, Kuletsa moto, Kusalowa madzi, Kusapsa ndi dzimbiri, Kutseka kutentha, Kudzimamatira, Kusunga epoxy-resin, Kuwonongeka, Kubwezeretsanso ndi zina zotero.
Scrim yoyikidwa ingagwiritsidwe ntchito ngati zipangizo zoyambira kupanga chivundikiro cha galimoto, awning yopepuka, mbendera, nsalu yoyendera etc.
Ma scrims opangidwa ndi triaxial angagwiritsidwenso ntchito popanga ma Sail laminates, ma rackets a tennis a patebulo, ma Kite boards, ukadaulo wa Sandwich wa ma skis ndi ma snowboards. Wonjezerani mphamvu ndi mphamvu yokoka ya chinthu chomalizidwa.
Masewero opangidwa ndi ma laminate awa anali olimba komanso othamanga kuposa masewero wamba, opangidwa mothithikana. Izi zimachitika chifukwa cha pamwamba pake posalala pa masewero atsopano, zomwe zimapangitsa kuti mpweya usamayende bwino komanso kuti mpweya umayenda bwino, komanso chifukwa chakuti masewero otere ndi opepuka komanso chifukwa cha zimenezi ndi othamanga kuposa masewero opangidwa mothithikana. Komabe, kuti tikwaniritse bwino masewero ndi kupambana mpikisano, kukhazikika kwa mawonekedwe a sewero la aerodynamic komwe kunapangidwa poyamba ndikofunikira. Kuti tifufuze momwe masewero atsopano angakhalire okhazikika pansi pa mphepo zosiyanasiyana, tinachita mayeso ambiri okoka pa nsalu zosiyanasiyana zamakono, zomangidwa mothithikana. Pepala lomwe laperekedwa pano likufotokoza momwe masewero atsopano alili otambasuka komanso olimba.
Polyester (PET)
Mtundu wofala kwambiri wa polyester ndi ulusi wofala kwambiri womwe umagwiritsidwa ntchito mu nsalu yotchinga; umatchedwanso dzina la Dacron. PET imakhala yolimba kwambiri, yolimba kwambiri, yolimba kwambiri pa UV, yolimba kwambiri komanso yotsika mtengo. Kusayamwa bwino kumalola ulusiwo kuti uume mwachangu. PET yasinthidwa ndi ulusi wolimba kwambiri pa ntchito zazikulu zothamanga, koma ikadali nsalu yotchinga yotchuka kwambiri chifukwa cha mtengo wotsika komanso kulimba kwambiri. Dacron ndi dzina la ulusi wa Dupont's Type 52 high modulus wopangidwa makamaka pa nsalu yotchinga. Allied Signal yapanga ulusi wotchedwa 1W70 polyester womwe uli ndi mphamvu yolimba ya 27% kuposa Dacron. Mayina ena amalonda ndi Terylene, Tetoron, Trevira ndi Diolen.
PET
Filimu ya PET ndiyo filimu yofala kwambiri yomwe imagwiritsidwa ntchito popanga nsalu yotchinga. Ndi mtundu wa ulusi wa PET wopangidwa ndi extruded komanso wozungulira mbali ziwiri. Ku US ndi Britain, mayina odziwika bwino amalonda ndi Mylar ndi Melinex.
Nsalu yophimba denga
M'zaka za m'ma 1970, opanga sitima anayamba kulumikiza zinthu zosiyanasiyana zokhala ndi makhalidwe osiyanasiyana kuti agwirizane ndi makhalidwe a chilichonse. Kugwiritsa ntchito mapepala a PET kapena PEN kumachepetsa kutambasuka mbali zonse, komwe nsalu zimakhala zogwira mtima kwambiri popita ku ulusi. Kupaka utoto kumathandizanso kuti ulusi uikidwe m'njira zowongoka, zosasinthasintha. Pali njira zinayi zazikulu zomangira:
Filimu-yolemba-filimu kapena filimu-yoikamo-filimu (filimu-yolemba-filimu)
Mu kapangidwe kameneka, chitsulo chopondera kapena ulusi (zoikamo) zimayikidwa pakati pa zigawo za filimu. Motero ziwalo zonyamula katundu zimayikidwa molunjika, zomwe zimapangitsa kuti ulusi ukhale wokwera kwambiri, pomwe nsalu yolukidwa imakhala ndi kutambasuka kwapadera kwa nsaluyo. Filimu yopaka utoto kuzungulira ulusiyo imapanga mgwirizano wolimba komanso wodalirika womwe umachepetsa kuchuluka kwa guluu wofunikira. Mu nsalu yapamwamba kwambiri, ulusi kapena ulusiwo umakanikizidwa panthawi yopaka utoto.
Zoyipa zake ndi izi: filimuyi siilimbana ndi kusweka kapena kupindika ngati nsalu yolukidwa, siiteteza ulusi wa kapangidwe kake ku kuwala kwa UV. Nthawi zina chitetezo cha UV chimawonjezeredwa.
