I-Fiberglass Scrim ene-Flame Retardant

I-scrim ebekwe kahle ibukeka njengegridi noma i-lattice. Yenziwe ngemikhiqizo ye-filament eqhubekayo (ama-yarn). Ukuze kugcinwe ama-yarn endaweni efiselekayo ye-engeli yesokudla, kubalulekile ukuhlanganisa la ma-yarn ndawonye. Ngokungafani ne-roducts elukiwe, ukufakwa kwama-warp nama-weft yarn kuma-scrims abekwe kahle kumele kwenziwe ngokubopha ngamakhemikhali. Ama-weft yarn abekwa nje phansi. Lokhu kufezwa ngenqubo yokukhiqiza.

Ngokuvamile ama-scrim abekwe kahle acishe abe ngu-20 - 40% amancane kunemikhiqizo elukiwe eyenziwe ngentambo efanayo futhi enokwakhiwa okufanayo.
Izindinganiso eziningi zaseYurophu zidinga ukuthi ulwelwesi lokufulela lube nomkhawulo omncane wezinto ezibonakalayo kuzo zombili izinhlangothi ze-scrim. Ama-scrim abekwe kahle asiza ekukhiqizeni imikhiqizo emincane ngaphandle kokwamukela amanani obuchwepheshe aphansi. Kungenzeka ukonga ngaphezu kwama-20% wezinto zokusetshenziswa ezifana ne-PVC noma i-PO.
Ama-scrim kuphela avumela ukukhiqizwa kwe-membrane yokuphahla enesilinganiselo esinezingqimba ezintathu (1.2 mm) encane kakhulu evame ukusetshenziswa eYurophu Ephakathi. Izindwangu azikwazi ukusetshenziselwa ama-membrane okuphahla anciphile kuno-1.5 mm.
Isakhiwo se-scrim esibekwe kahle asibonakali kangako kumkhiqizo wokugcina kunesakhiwo sezinto ezilukiwe. Lokhu kuphumela ebusweni obubushelelezi nobulinganayo bomkhiqizo wokugcina.
Ubuso obubushelelezi bemikhiqizo yokugcina equkethe ama-scrims abekwe phansi buvumela ukushisela noma ukunamathisela izendlalelo zemikhiqizo yokugcina kalula nangokuhlala isikhathi eside komunye nomunye.
Izindawo ezibushelelezi zizomelana nokungcola isikhathi eside futhi ziqhubeke njalo.
Ukusetshenziswa kwe-glassfibre scrim nonwovens eziqinisiwe kuvumela isivinini esikhulu somshini ekukhiqizweni kwamashidi ophahla e-bitu-men. Ngakho-ke, ukudabuka kwesikhathi kanye nomsebenzi onzima esitshalweni samashidi ophahla e-bitumen kungavinjelwa.
Amanani omshini wamashidi ophahla lwe-bitumen athuthukiswa kancane kancane yi-scrims.
Izinto ezivame ukudabuka kalula, njengephepha, i-foil noma amafilimu avela kumapulasitiki ahlukene, zizovinjelwa ukudabuka ngempumelelo ngokuzinamathisela ngezikrimu ezibekiwe.
Nakuba imikhiqizo elukiwe inganikezwa i-loomstate, i-scrim ebekwe kahle iyohlala ifakelwa. Ngenxa yalokhu sinolwazi olubanzi maqondana nokuthi iyiphi i-binder engafaneleka kakhulu ekusetshenzisweni okuhlukene. Ukukhetha i-glue efanele kungathuthukisa kakhulu ukubopha kwe-scrim ebekwe kahle nomkhiqizo wokugcina.
Iqiniso lokuthi i-warp ephezulu nephansi kuma-scrims abekwe kahle izohlala ihlangothini elifanayo lezintambo ze-weft liqinisekisa ukuthi izintambo ze-warp zizohlala zicindezelekile. Ngakho-ke amandla okudonsa ohlangothini lwe-warp azomuncwa ngokushesha. Ngenxa yalomphumela, izintambo ezibekwe kahle zivame ukukhombisa ukunwebeka okuncishisiwe kakhulu. Lapho unamathisela i-scrim phakathi kwezingqimba ezimbili zefilimu noma ezinye izinto, kuzodingeka inhlaka encane futhi ukuhlangana kwe-laminate kuzothuthukiswa. Ukukhiqizwa kwezintambo kudinga inqubo yokomisa ngokushisa njalo. Lokhu kuholela ekuncipheni kwe-polyester nezinye izintambo ze-thermoplastic okuzothuthukisa ukwelashwa okulandelayo okwenziwa yikhasimende.
