Tso scrim zoo li lub grid lossis lattice. Nws yog ua los ntawm cov khoom siv filament tas mus li (xov). Yuav kom khaws cov xov paj hauv qhov chaw xav tau sab xis-angled nws yog qhov tsim nyog los koom nrog cov xov paj no ua ke. Nyob rau hauv sib piv rau woven roducts qhov kev kho ntawm cov xov paj warp thiab weft hauv tso scrims yuav tsum tau ua los ntawm kev sib txuas tshuaj lom neeg. weft xov paj tsuas yog tso hla hauv qab Qhov no yog ua tiav los ntawm kev tsim khoom.
Feem ntau tso scrims yog hais txog 20 - 40% thinner dua li woven cov khoom ua los ntawm tib lub xov thiab nrog ib tug zoo sib xws kev tsim kho.
Ntau tus qauv European xav kom cov ntaub thaiv ru tsev tsawg kawg nkaus rau ob sab ntawm daim scrim. Cov scrims uas muab tso ua ke pab tsim cov khoom nyias dua yam tsis tas yuav lees txais cov nqi qis dua. Nws muaj peev xwm txuag tau ntau dua 20% ntawm cov khoom siv raw xws li PVC lossis PO.
Tsuas yog cov scrims tso cai rau kev tsim cov ntaub thaiv ru tsev peb txheej sib npaug (1.2 hli) nyias heev uas feem ntau siv hauv Central Europe. Cov ntaub tsis tuaj yeem siv rau cov ntaub thaiv ru tsev uas nyias dua 1.5 hli.
Cov qauv ntawm ib tug pw scrim yog tsis pom nyob rau hauv qhov kawg khoom dua li cov qauv ntawm woven cov ntaub ntawv. Qhov no ua rau ib tug smoother thiab ntau txawm nto ntawm qhov kawg khoom.
Lub du nto ntawm cov khoom kawg uas muaj cov scrims pw tso cai rau weld lossis nplaum cov khaubncaws sab nraud povtseg ntawm cov khoom kawg yooj yim dua thiab ruaj khov nrog txhua lwm yam.
Cov chaw du dua yuav tiv taus kev qias neeg ntev dua thiab nyob ntev dua.
Kev siv cov iav fiber scrim reinforced nonwovens ua rau lub tshuab ua haujlwm ceev dua rau kev tsim cov ru tsev bitu-men. Yog li ntawd, lub sijhawm thiab kev siv zog ntau hauv lub Hoobkas ua cov ru tsev bitumen tuaj yeem tiv thaiv tau.
Cov nqi kho tshuab ntawm cov ntawv ru tsev bitumen tau txhim kho zoo los ntawm cov scrims.
Cov ntaub ntawv uas feem ntau yuav dua yooj yim, xws li ntawv, ntawv ci lossis zaj duab xis los ntawm ntau hom yas, yuav raug tiv thaiv kom tsis txhob dua los ntawm kev laminating cov no nrog cov scrims uas tau tso.
Txawm hais tias cov khoom siv woven yuav raug muab los ntawm loomstate, ib daim ntaub pw yuav ib txwm raug impregnated. Vim li no peb muaj kev paub dav dav txog cov binder twg yuav zoo tshaj plaws rau ntau daim ntawv thov. Kev xaiv cov nplaum zoo yuav ua rau kev sib txuas ntawm daim ntaub pw nrog cov khoom kawg zoo heev.
Qhov tseeb tias cov warp sab saud thiab sab qis hauv cov scrims pw yuav ib txwm nyob rau tib sab ntawm cov xov weft lav tias cov xov warp yuav ib txwm nyob hauv qab kev ntxhov siab. Yog li ntawd, lub zog tensile hauv kev coj warp yuav raug nqus tam sim ntawd. Vim yog qhov no, cov scrims pw feem ntau qhia txog kev txo qis elongation. Thaum laminating ib tug scrim ntawm ob txheej ntawm zaj duab xis lossis lwm yam ntaub ntawv, tsawg dua cov nplaum yuav tsum tau thiab qhov cohesion ntawm lub laminate yuav raug txhim kho. Kev tsim cov scrims ib txwm xav tau ib tug thermal ziab txheej txheem. Qhov no ua rau preshrinking ntawm cov polyester thiab lwm yam thermoplastic yarns uas yuav txhim kho ntau tom qab kev kho mob ua los ntawm cov neeg siv khoom.
Yog tias koj muaj lus nug txog txhua qhov kev tso scrims thiab fiberglass khoom, xws li
polyester scrim nrog PVOH binder,
