I-Fiberglass Scrim ene-Flame Retardant

i-crim ebekiweyo ibonakala njengegridi okanye i-lattice. Yenziwe kwiimveliso zefilament eziqhubekayo (imisonto). Ukuze ugcine imisonto ikwindawo efunwayo ye-engile ekunene kuyimfuneko ukudibanisa le misonto kunye. Ngokuchaseneyo ne-roducts elukiweyo ukulungiswa kwemisonto ye-warp kunye ne-weft kwi-scrims ebekiweyo kufuneka yenziwe nge-chemical bonding. Imisonto yeweft ibekwe ngokulula inqamleze umzantsi Oku kuphunyezwa ngenkqubo yokuvelisa.

Ngokuqhelekileyo izikrweqe ezibekweyo zimalunga ne-20 – 40 % zibhityile kuneemveliso ezilukiweyo ezenziwe ngomsonto ofanayo kunye nolwakhiwo olufanayo.
Imigangatho emininzi yaseYurophu ifuna uphahla inwebu ubuncinci bokugqunywa kwemathiriyeli kumacala omabini eskrim. Izikrweqe ezibekiweyo zinceda ukuvelisa iimveliso ezibhityileyo ngaphandle kokwamkela amaxabiso aphantsi obugcisa. Kuyenzeka ukuba ugcine ngaphezulu kwe-20 % yezinto ezikrwada ezifana nePVC okanye iPO.
Kuphela zizikrelemnqa ezivumela ukuveliswa kwenwebu ecekethekileyo elinganayo yophahla oluyi-1.2 mm edla ngokusetyenziswa kuMbindi Yurophu. Ilaphu alinakusetyenziselwa ukuphahla i-membrane ezinqabileyo kune-1.5 mm.
Ubume be-scrim ebekiweyo bubonakala kancinci kwimveliso yokugqibela kunesakhiwo semathiriyeli elukiweyo. Oku kubangela umphezulu ogudileyo kunye nangaphezulu kwimveliso yokugqibela.
Umphezulu ogudileyo weemveliso zokugqibela eziqulathe ii-laid scrims zivumela ukuwelda okanye ukuncamathelisa iileya zeemveliso zokugqibela ngokulula nangokuzinzileyo kunye nomnye.
Imiphezulu egudileyo iya kuxhathisa umhlaba ixesha elide kwaye ngokuqhubekayo.
Ukusetyenziswa kwe-glassfibre scrim eyomeleziweyo i-nonwovens per-mits isantya esiphezulu somatshini wokuvelisa amashiti ophahla lwebhitu-amadoda. Iinyembezi zexesha kunye nomsebenzi onzima kwiplanti yophahla lwebhitumene zinokuthintelwa.
Amaxabiso oomatshini bamashiti ophahla lwebhitumene aphuculwa kancinci ngabadlali.
Izixhobo ezithanda ukukrazuka lula, njengephepha, ifoyile okanye iifilim ezivela kwiiplastiki ezahlukeneyo, ziya kuthintelwa ukuba zingakrazuki ngokufanelekileyo ngokuzilamisa ngezikrimu ezibekiweyo.
Ngelixa iimveliso ezilukiweyo zinokubonelelwa nge-loomstate, iscrim esibekiweyo siya kuhlala similwe. Ngenxa yale nyaniso sinolwazi olubanzi malunga nokuba sesiphi isibophelelo esinokulungela izicelo ezahlukeneyo. Ukukhetha i-adhesive efanelekileyo kunokunyusa ukudibanisa kwe-crim ebekiweyo kunye nemveliso yokugqibela kakhulu.
Inyaniso yokuba i-warp ephezulu kunye nesezantsi kwi-scrims ebekiweyo iya kuhlala ikwicala elinye leentambo ze-weft iqinisekisa ukuba imisonto ye-warp iya kuhlala iphantsi koxinzelelo. Ke ngoko amandla aqinileyo kwicala le-warp aya kuthinjwa kwangoko. Ngenxa yale mpembelelo, i-scrims ebekiweyo idla ngokubonisa ukuncitshiswa kakhulu kwe-elongation.Xa i-laminating i-scrim phakathi kweengqimba ezimbini zefilimu okanye ezinye izinto, i-adhesive encinci iya kufuneka kwaye ukudibanisa kwe-laminate kuya kuphucula. inkqubo yokomisa. Oku kukhokelela ekuncipheni kwangaphambili kwepolyester kunye neminye imisonto ye-thermoplastic eya kuphucula kakhulu unyango olulandelayo olwenziwe ngumthengi.
