I-scrim ebekwe kakuhle ifana negridi okanye ilathisi. Yenziwe ngeemveliso ze-filament eziqhubekayo (iintambo).
Ukuze imisonto ihlale kwindawo efunekayo ekhoneni lasekunene, kuyimfuneko ukuyidibanisa
Ngokwahlukileyo kwiimveliso ezilukiweyo, ukuqiniswa kwemisonto ye-warp kunye ne-weft ku
ii-scrims ezibekwe kufuneka zenziwe ngokubophelela ngamakhemikhali. Iintambo ze-weft zibekwe nje ezantsi
Oku kufezekiswa ngenkqubo yokuvelisa.
Iskrim ebekwe phantsiiveliswa ngamanyathelo amathathu asisiseko:
INYATHELO 1: Amaphepha eentambo ze-Warp anikwa ngemiqadi yecandelo okanye ngokuthe ngqo kwi-creel.
INYATHELO 2: Isixhobo esikhethekileyo esijikelezayo, okanye i-turbine, sibeka imisonto enqamlezileyo ngesantya esiphezulu
okanye phakathi kwamaphepha okugoba. Iskrim ifakwa ngoko nangoko ngenkqubo yokuncamathelisa ukuqinisekisa ukuqiniswa kwemisonto yomatshini kunye neyendlela enqamlezileyo.
INYATHELO 3: I-scrim ekugqibeleni iyomiswa, inyangwa ngobushushu kwaye ibotshelelwe kwityhubhu
Umahluko phakathi kweScrims ezibekwe kunye neeScrims ezilukiweyo:
Iinkcukacha ze-Laid Scrims zethu:
| Ububanzi: | 500 ukuya kwi-2500 mm | Ubude boMqulu: | Ukuya kuthi ga kwi-50 000 m | Uhlobo lweentambo: | Iglasi, ipolyester, ikhabhoni | ||||||||
| Ulwakhiwo: | Isikwere, esineecala ezintathu | Iipateni: | Ukusuka kwi-0.8 yeentambo/cm ukuya kwi-3 yeentambo/cm | Ukudibanisa: | I-PVOH, i-PVC, i-Acrylic, eyenziwe ngokwezifiso | ||||||||
Iingenelo zeIiScrims ezibekwe:
Ngokubanziii-scrims ezibekwezincinci nge-20 - 40% kuneemveliso ezilukiweyo ezenziwe ngomsonto ofanayo kwaye zenziwe ngendlela efanayo.
Imigangatho emininzi yaseYurophu ifuna ukuba kubekho ubuncinci bezinto ezigqunywe kumacala omabini e-scrim ukuze ii-membranes zophahla zibe nophahla.Iiskrim ezibekwe phantsikunceda ukuvelisa iimveliso ezincinci ngaphandle kokwamkela amaxabiso obuchwephesha aphantsi. Kunokwenzeka ukonga ngaphezulu kwe-20% yezinto ezikrwada ezifana nePVC okanye i-PO.
Kuphela zii-scrims ezivumela ukuveliswa kwe-membrane yophahla ebhityileyo kakhulu enomgangatho olinganayo onezintlu ezintathu (1.2 mm) esetyenziswa rhoqo kwi-Central Europe. Amalaphu awanakusetyenziselwa ii-membrane zophahla ezibhityileyo kune-1.5 mm.
Ulwakhiwo lwei-scrim ebekwe phantsiayibonakali kangako kwimveliso yokugqibela kunesakhiwo sezinto ezilukiweyo. Oku kubangela ukuba umphezulu wemveliso yokugqibela ube bushelelezi kwaye ulingane.
Umphezulu ogudileyo weemveliso zokugqibela ezinee-scrims ezibekiweyo uvumela ukutshixa okanye ukuncamathisela iileya zeemveliso zokugqibela ngokulula nangokuhlala ixesha elide.
Iindawo ezithambileyo ziya kukwazi ukumelana nokungcola ixesha elide kwaye zihlala zinjalo.
Ukusetyenziswa kwei-glassfiber scrimIzinto ezingalukwanga eziqinisiweyo zivumela isantya esiphezulu somatshini sokwenza amashiti ophahla e-bitu-men. Ngenxa yoko, ukukrazuka kwexesha kunye nomsebenzi onzima kwisityalo seshiti yophahla lwe-bitumen kunokuthintelwa.
Amaxabiso oomatshini beeshiti zophahla lwebhitumen aphuculwa kancinci yi-scrims.
Izinto ezidla ngokukrazuka lula, njengephepha, ifoyile okanye iifilimu ezivela kwiiplastiki ezahlukeneyo, ziya kuthintelwa ekukrazukeni ngempumelelo ngokuzigquma nge-laminateii-scrims ezibekwe.
Nangona iimveliso ezilukiweyo zinokubonelelwa nge-loomstate,i-scrim ebekwe phantsiiya kuhlala ifunxwa. Ngenxa yesi sizathu sinolwazi olubanzi malunga nokuba yeyiphi i-binder enokufaneleka kakhulu kwiindlela ezahlukeneyo zokusetyenziswa. Ukukhetha i-glue efanelekileyo kunokuphucula ukubopha kwe-bondingi-scrim ebekwe phantsingemveliso yokugqibela kakhulu.
Inyani yokuba i-warp ephezulu nesezantsi kuii-scrims ezibekweiya kuhlala ikwicala elinye leentambo ze-weft iqinisekisa ukuba iintambo ze-warp ziya kuhlala zixinezelekile. Ngenxa yoko amandla okuxinana kwicala le-warp aya kufunxwa ngoko nangoko. Ngenxa yesi siphumo,ii-scrims ezibekweidla ngokubonisa ukunwebeka okunciphileyo. Xa ulayita i-scrim phakathi kweengqimba ezimbini zefilimu okanye ezinye izinto, kuya kufuneka i-glue encinci kwaye ukuhlangana kwe-laminate kuya kuphuculwa. Ukuveliswa kwee-scrims kusoloko kufuna inkqubo yokomisa ngobushushu. Oku kukhokelela ekuncipheni kwe-polyester kunye nezinye iintambo ze-thermoplastic okuya kuphucula kakhulu unyango oluza kwenziwa ngumthengi.
Ulwakhiwo oluqhelekileyo lweIiScrims ezibekwe:
I-warp enye
Olu lolona lwakhiwo luqhelekileyo lwe-scrim. Intambo yokuqala ye-warp* phantsi kwentambo ye-weft** ilandelwa yintambo ye-warp ngaphezulu kwentambo ye-weft. Le patheni iphindaphindwa kububanzi bonke. Ngokwesiqhelo isithuba phakathi kwentambo siqhelekile kububanzi bonke. Kwiindawo ezidibana kuzo imisonto emibini iya kuhlala idibana.
* i-warp = yonke imisonto kwicala lomatshini
** i-weft = yonke imisonto inqamleze icala
I-warp ephindwe kabini
Imisonto ye-warp ephezulu nesezantsi iya kuhlala ibekwe phezu komnye ukuze imisonto ye-weft ihlale iqinile phakathi komsonto we-warp ophezulu nowe-warp osezantsi. Kwiindawo ezidibana kuzo imisonto emithathu iya kuhlala idibana.
Iilaminate ezingezizo ezolukiweyo zeScrim
I-scrim (eyodwa okanye ephindwe kabini) igqunywe kwi-nonwoven (eyenziwe ngeglasi, i-polyester okanye ezinye iifayibha). Kunokwenzeka ukuvelisa ii-laminates ezine-nonwovens ezinobunzima obuphakathi kwe-0.44 ukuya kwi-5.92 oz./sq.yd.
