I-scrim ebekwe kahle ibukeka njengegridi noma i-lattice. Yenziwe ngemikhiqizo ye-filament eqhubekayo (ama-yarn).
Ukuze ugcine imicu isendaweni oyifunayo ekhoneni lesokudla, kubalulekile ukuhlanganisa lezi
Ngokuphambene nemikhiqizo elukiwe, ukufakwa kwezintambo ezigoqekile kanye nezigoqekile ku
ama-scrims abekwe kumele enziwe ngokubopha ngamakhemikhali. Izintambo ze-weft zibekwe nje phansi
Lokhu kufezwa ngenqubo yokukhiqiza.
I-scrim ebekwe phansikukhiqizwa ngezinyathelo ezintathu eziyisisekelo:
ISINYATHELO 1: Amashidi entambo ye-Warp anikezwa ngemishayo yesigaba noma ngqo kusuka ku-creel.
ISINYATHELO 2: Idivayisi ekhethekile ejikelezayo, noma i-turbine, ibeka izintambo eziphambene ngesivinini esikhulu
noma phakathi kwamashidi okugoqa. I-scrim ifakwa ngokushesha ngohlelo lokunamathela ukuqinisekisa ukuqina kwezintambo zomshini kanye nezindlela eziphambene.
ISINYATHELO 3: I-scrim ekugcineni iyomiswa, iphathwa ngokushisa futhi iboshwe epayipini
Umehluko we-Scrims Ebekwe kanye ne-Scrims Ezilukiwe:
Imininingwane ye-Laid Scrims yethu:
| Ububanzi: | 500 kuya ku-2500 mm | Ubude bokugoqa: | Kufika ku-50 000 m | Uhlobo Lwezintambo: | Ingilazi, i-polyester, ikhabhoni | ||||||||
| Ukwakhiwa: | Isikwele, esiqondiswe kathathu | Amaphethini: | Kusukela ku-0.8 yezintambo/cm kuya ku-3 yezintambo/cm | Ukubopha: | I-PVOH, i-PVC, i-Acrylic, eyenziwe ngokwezifiso | ||||||||
Izinzuzo zeAma-Scrims Abekwe Phansi:
Ngokuvamileama-scrims abekwezincane ngo-20 - 40% kunemikhiqizo elukiwe eyenziwe ngentambo efanayo futhi enokwakhiwa okufanayo.
Izindinganiso eziningi zaseYurophu zidinga ukuthi ulwelwesi lokuphahla lube nombozo omncane wezinto ezibonakalayo kuzo zombili izinhlangothi ze-scrim.Ama-scrims abekwe phansikusize ekukhiqizeni imikhiqizo emincane ngaphandle kokwamukela amanani obuchwepheshe aphansi. Kungenzeka ukonga ngaphezu kuka-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-i-scrim ebekwe phansiayibonakali kangako emkhiqizweni 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 kwei-glassfibre scrimIzingubo ezingalukiwe eziqinisiwe zivumela isivinini esiphezulu somshini wokukhiqiza amashidi ophahla e-bitu-men. Ngakho-ke, ukudabuka kwesikhathi kanye nomsebenzi onzima esitshalweni seshidi lophahla lwe-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 nge-laminateama-scrims abekwe.
Nakuba imikhiqizo elukiwe inganikezwa i-loomstate,i-scrim ebekwe phansiizohlala ifakelwa. Ngenxa yalokhu sinolwazi olubanzi mayelana nokuthi iyiphi i-binder engafaneleka kakhulu ekusetshenzisweni okuhlukene. Ukukhetha i-glue efanele kungathuthukisa ukubopha kwe-i-scrim ebekwe phansingomkhiqizo wokugcina kakhulu.
Iqiniso lokuthi i-warp ephezulu nephansi kuama-scrims abekwekuzohlala kusehlangothini olufanayo lwezintambo ze-weft kuqinisekisa ukuthi izintambo ze-warp zizohlala zicindezelekile. Ngakho-ke amandla okudonsa ohlangothini lwe-warp azomuncwa ngokushesha. Ngenxa yalomphumela,ama-scrims abekwekuvame ukukhombisa ukunwebeka okuncishisiwe kakhulu. Lapho unamathisela i-scrim phakathi kwezingqimba ezimbili zefilimu noma ezinye izinto, kuzodingeka inhlaka encane futhi ukuhlangana kwe-laminate kuzothuthukiswa. Ukukhiqizwa kwama-scrim kudinga inqubo yokomisa ngokushisa njalo. Lokhu kuholela ekuncipheni kwe-polyester nezinye izindwangu ze-thermoplastic okuzothuthukisa kakhulu ukwelashwa okulandelayo okwenziwa yikhasimende.
Izakhiwo ezijwayelekile zeAma-Scrims Abekwe Phansi:
I-warp eyodwa
Lokhu ukwakhiwa kwe-scrim okuvame kakhulu. Intambo yokuqala ye-warp* ngaphansi kwentambo ye-weft** ilandelwa yintambo ye-warp ngaphezu kwentambo ye-weft. Le patheni iphindaphindwa kulo lonke ububanzi. Ngokuvamile isikhala phakathi kwezintambo sivamile kulo lonke ububanzi. Ezimpambanweni zemigwaqo izintambo ezimbili zizohlala zihlangana.
* i-warp = yonke imicu iqondiswe emshinini
** i-weft = yonke imicu iqonde ngqo
Ukugoba okuphindwe kabili
Izintambo ezigoqekile ezingenhla nezingezansi zizohlala zibekwe phezu komunye ukuze izintambo ezigoqekile zihlale ziqinile phakathi kwentambo egoqekile engenhla nephansi. Ezimpambanweni zemigwaqo izintambo ezintathu zizohlala zihlangana.
Ama-laminate angelukiwe acwebezelayo
I-scrim (eyodwa noma ephindwe kabili) inamathiselwa ku-nonwoven (eyenziwe ngengilazi, i-polyester noma eminye imicu). Kungenzeka ukukhiqiza ama-laminate ane-nonwovens anesisindo esisukela ku-0.44 kuya ku-5.92 oz./sq.yd.
