Ib tug nteg scrim zoo li ib daim phiaj los yog lattice. Nws yog tsim los ntawm cov khoom siv filament txuas ntxiv (yarns).
Txhawm rau kom cov yarns nyob rau hauv qhov xav tau txoj cai-angled nws yog qhov tsim nyog los koom nrog cov no
yarns ua ke. Nyob rau hauv sib piv rau cov khoom woven lub fixation ntawm warp thiab weft yarns nyob rau hauv
nteg scrims yuav tsum tau ua los ntawm kev sib txuas tshuaj. weft yarns tsuas yog pw hauv qab
Qhov no yog ua tiav los ntawm kev tsim khoom.
Lub nteg scrimyog tsim nyob rau hauv peb theem pib:
KAUJ RUAM 1: Cov ntaub ntawv xov paj warp yog pub los ntawm cov kab hluav taws xob los yog ncaj qha los ntawm cov creel.
KAUJ RUAM 2: Ib qho tshwj xeeb rotating ntaus ntawv, los yog turbine, lays cross yarns ntawm kev kub ceev ntawm
los yog nruab nrab ntawm daim ntawv warp. Lub scrim yog tam sim ntawd impregnated nrog ib tug nplaum system los xyuas kom meej lub fixation ntawm lub tshuab- thiab cross-directional yarns.
KAUJ RUAM 3: Cov scrim yog thaum kawg tau qhuav, thermally kho thiab mob ntawm ib lub raj
Qhov txawv ntawm Laid Scrims thiab Woven Scrims:
Cov specifications ntawm peb Laid Scrims:
| Dav: | 500-2500 hli | Roll Length: | Mus txog 50 000 m | Hom xov paj: | iav, polyester, carbon | ||||||||
| Kev tsim kho: | Square, tri-directional | Cov qauv: | Los ntawm 0.8 yarns / cm mus rau 3 yarns / cm | Bonding: | PVOH, PVC, Acrylic, customized | ||||||||
Qhov zoo ntawmLaid Scrims:
Feem ntautso scrimsyog li ntawm 20 - 40% thinner dua cov khoom lag luam uas ua los ntawm tib cov xov paj thiab nrog kev tsim kho zoo ib yam.
Ntau cov qauv European xav tau rau cov vov tsev cov ntaub ntawv tsawg kawg nkaus ntawm ob sab ntawm cov scrim.Laid scrimspab tsim cov khoom thinner yam tsis tas yuav tsum tau txais kev txo qis kev nqis peev. Nws tuaj yeem txuag tau ntau dua 20% ntawm cov khoom siv raw xws li PVC lossis PO.
Tsuas yog scrims tso cai tsim cov khoom nyias nyias symmetrical peb txheej vov tsev membrane (1.2 hli) uas feem ntau siv hauv Central Europe. Cov ntaub tsis tuaj yeem siv rau cov vov tsev uas nyias nyias dua 1.5 hli.
Tus qauv ntawm aua scrimtsis tshua pom nyob rau hauv cov khoom kawg tshaj li cov qauv ntawm cov ntaub ntawv woven. Qhov no ua rau lub smoother thiab ntau dua nto ntawm cov khoom kawg.
Lub smoother nto ntawm cov khoom kawg uas muaj nteg scrims tso cai rau weld los yog nplaum txheej ntawm cov khoom kawg yooj yim dua thiab durably nrog ib leeg.
Cov npoo smoother yuav tiv taus cov av ntev dua thiab tsis tu ncua.
Kev siv ntawmiav fiber scrimreinforced nonwovens per-mits siab dua tshuab speeds rau zus tau tej cov bitu-txiv neej ru tsev ntawv. Lub sij hawm thiab kev ua hauj lwm hnyav kua muag nyob rau hauv bitumen ru tsev ntawv cog yog li ntawd yuav tiv thaiv.
Cov cuab yeej cuab tam ntawm cov nplooj ntawv bitumen ru tsev yog qhov zoo dua los ntawm scrims.
Cov ntaub ntawv uas nyiam tsim kua muag tau yooj yim, xws li ntawv, ntawv ci lossis cov yeeb yaj kiab los ntawm cov yas sib txawv, yuav raug tiv thaiv los ntawm kev tsim kua muag zoo los ntawm laminating cov no.tso scrims.
Whilst woven khoom tej zaum yuav muab loomstate, aua scrimyuav tau impregnated. Vim qhov tseeb no peb muaj kev paub dav dav txog qhov twg binder yuav zoo tshaj plaws rau kev siv sib txawv. Qhov kev xaiv ntawm cov nplaum nplaum yuav txhim khu kev sib raug zoo ntawm covua scrimnrog cov khoom kawg considerably.
Qhov tseeb hais tias lub Upper thiab qis warp nyob rau hauvtso scrimsyuav ib txwm nyob ntawm tib sab ntawm cov xov paj weft guarantees tias warp yarns yuav ib txwm nyob rau hauv nruj. Yog li ntawd, tensile powers nyob rau hauv warp kev taw qhia yuav absorbed tam sim ntawd. Vim qhov no tshwm sim,tso scrimsFeem ntau qhia qhov txo qis elongation.Thaum laminating ib tug scrim ntawm ob txheej ntawm zaj duab xis los yog lwm yam ntaub ntawv, yuav tsum tau tsawg adhesion thiab lub cohesion ntawm lub laminate yuav zoo tuaj.Qhov ntau lawm ntawm scrims ib txwm yuav tsum tau ib tug thermal drying txheej txheem. Qhov no ua rau preshrinking ntawm polyester thiab lwm yam thermoplastic yarns uas yuav txhim kho cov kev kho mob tom ntej los ntawm cov neeg siv khoom.
Hom kev tsim kho ntawmLaid Scrims:
Ib leeg warp
Qhov no yog qhov feem ntau scrim siv. Thawj warp * xov nyob rau hauv ib tug weft ** xov yog ua raws li los ntawm ib tug warp xov saum lub weft xov. Cov qauv no rov ua dua thoob plaws qhov dav. Feem ntau qhov sib nrug ntawm cov xov yog tsis tu ncua hla tag nrho qhov dav. Ntawm kev sib tshuam ob txoj xov yuav ib txwm sib ntsib.
* warp = tag nrho cov xov hauv tshuab kev taw qhia
** weft = tag nrho cov xov nyob rau hauv txoj kev hla
Ob chav warp
Lub qaum thiab qis warp threads yuav ib txwm muab tso rau ib qho rau lwm qhov kom cov xov weft yuav tsum tau kho ntawm ib sab thiab qis warp xov. Ntawm qhov kev sib tshuam peb txoj xov yuav ib txwm sib ntsib.
Scrim nonwoven laminates
Ib qho scrim (ib zaug lossis ob zaug warp) yog laminated mus rau ib qho nonwoven (ua los ntawm iav, polyester los yog lwm yam fibers). Nws yog ua tau los tsim laminates nrog nonwovens hnyav los ntawm 0.44 mus rau 5.92 oz./sq.yd.
