I-scrim ebekiwe ibukeka njengegridi noma i-lattice.Yenziwe ngemikhiqizo ye-filament eqhubekayo (imicu).
Ukuze ugcine izintambo zisesimweni esifiselekayo se-engeli kwesokudla kuyadingeka ukujoyina lezi
izintambo ndawonye.Ngokuphambene nemikhiqizo elukiweyo ukulungiswa kwe-warp ne-weft yarns in
izigebengu ezibekiwe kumele zenziwe nge-chemical bonding.imicu ye-weft imane ibekwe ngaphesheya
Lokhu kufezwa ngenqubo yokukhiqiza.
I-scrim ebekiwekukhiqizwa ngezinyathelo ezintathu eziyisisekelo:
ISINYATHELO 1: Amashidi entambo ye-warp aphakelwa kusuka emishayweni yesigaba noma ngokuqondile ku-creel.
ISINYATHELO 2: Idivayisi ekhethekile ezungezisayo, noma i-turbine, ibeka izintambo eziphambanayo ngesivinini esikhulu
noma phakathi kwama-wap sheet.I-scrim ifakwa ngokushesha ngesistimu yokunamathela ukuze kuqinisekiswe ukulungiswa komshini- kanye nezintambo eziqondisayo.
ISINYATHELO SESI-3: I-scrim ekugcineni iyomiswa, ilashwe ngokushisa futhi ilinyazwe ngeshubhu
Umehluko we-Laid Scrims kanye ne-Woven Scrims:
Imininingwane ye-Laid Scrims yethu:
| Ububanzi: | 500 ukuze 2500 mm | Ubude bokugoqa: | Kufika ku-50 000 m | Uhlobo Lwezintambo: | Ingilazi, i-polyester, ikhabhoni | ||||||||
| Ukwakha: | Isikwele, i-tri-directional | Amaphethini: | Ukusuka ku-0.8 kuya ku-3 cm / cm | I-Bonding: | I-PVOH, i-PVC, i-Acrylic, eyenziwe ngokwezifiso | ||||||||
Izinzuzo zeI-Laid Scrims:
Ngokuvamilewabeka izigebengucishe izacile ngo-20 - 40% kunemikhiqizo elukiwe eyenziwe ngentambo efanayo futhi inokwakhiwa okufanayo.
Izindinganiso eziningi zaseYurophu zidinga ulwelwesi lokufulela ukumbozwa kwempahla ezinhlangothini zombili ze-scrim.Izigebengu ezibekiweukusiza ukukhiqiza imikhiqizo emincane ngaphandle kokwamukela amanani ezobuchwepheshe anciphile.Kungenzeka ukonga ngaphezu kwama-20 % wezinto ezingavuthiwe ezifana ne-PVC noma i-PO.
Izigebengu kuphela ezivumela ukukhiqizwa kolwelwesi oluncane lokufulela ngezingqimba ezintathu (1.2 mm) oluvame ukusetshenziswa e-Central Europe.Izindwangu azikwazi ukusetshenziselwa ulwelwesi lokufulela oluncane kuno-1.5 mm.
Isakhiwo se-awabeka isihlukuayibonakali kangako emkhiqizweni wokugcina kunesakhiwo sezinto ezilukiweyo.Lokhu kubangela ukuthi umkhiqizo wokugcina ube bushelelezi futhi ulingane.
Ingaphezulu elibushelelezi lemikhiqizo yokugcina equkethe ama-laid scrims livumela ukushisela noma ukunamathisela izingqimba zemikhiqizo yokugcina kalula nangokuqinile komunye nomunye.
Izindawo ezibushelelezi zizomelana nokungcoliswa isikhathi eside nangokuphikelela.
Ukusetshenziswa kwei-glassfibre scrimama-nonwovens aqinisiwe ama-per-mits aphezulu ngesivinini somshini wokukhiqiza amashidi ophahla lwe-bitu-amadoda.Ngakho-ke kungavinjelwa izinyembezi ezicindezela isikhathi nomsebenzi esitshalweni se-bitumen roof sheet.
Amanani emishini yamashidi ophahla lwebitumen athuthukiswa kancane kancane yizigebengu.
Izinto ezivame ukudabuka kalula, njengephepha, i-foil noma amafilimu avela kumapulasitiki ahlukene, zizovinjelwa ukuthi zingadabuki ngokuphumelelayo ngokuwalalisawabeka izigebengu.
Nakuba imikhiqizo elukiwe ingase ihlinzekwe nge-loomstate, awabeka isihlukuiyohlala ikhulelwe.Ngenxa yaleli qiniso sinolwazi olubanzi mayelana nokuthi isiphi isibophezelo esingalungela kangcono izinhlelo zokusebenza ezahlukene.Ukukhethwa kwe-adhesive efanele kungase kuthuthukise ukubopha kwe-wabeka isihlukungomkhiqizo wokugcina kakhulu.
Iqiniso lokuthi i-warp ephezulu nephansiwabeka izigebenguiyohlala ihlezi ohlangothini olulodwa lwezintambo ezisontekile iqinisekisa ukuthi imicu eqondile iyohlale ingaphansi kokucindezeleka.Ngakho-ke amandla aqinile ekuqondeni kwe-warp azothathwa ngokushesha.Ngenxa yalo mphumela,wabeka izigebengungokuvamile ubonisa ubude obuncishisiwe kakhulu.Lapho i-laminating i-scrim phakathi kwezingqimba ezimbili zefilimu noma ezinye izinto, ukunamathela okuncane kuzodingeka futhi ukuhlangana kwe-laminate kuzothuthukiswa.Ukukhiqizwa kwama-scrims kudinga njalo inqubo yokomisa okushisayo.Lokhu kuholela ekuncipheni kwe-polyester nezinye izintambo ze-thermoplastic okuzokwenza ngcono kakhulu ukwelashwa okulandelayo okwenziwa yikhasimende.
Izakhiwo ezijwayelekile zeI-Laid Scrims:
I-wap eyodwa
Lona ukwakhiwa kwe-scrim okuvame kakhulu.Intambo ye-warp* yokuqala ngaphansi kwentambo ye-weft** ilandelwa intambo ye-warp ngaphezu kwentambo ye-weft.Le phethini iphindaphindiwe kubo bonke ububanzi.Ngokujwayelekile isikhala phakathi kwemicu sivamile kubo bonke ububanzi.Ezimpambanweni zomgwaqo imicu emibili iyohlala ihlangana.
* i-warp = yonke imicu ekuqondeni komshini
** i-weft = yonke imicu ephambanayo
I-wap kabili
Izintambo ezigoqekayo ezingenhla nezingezansi ziyohlale zibekwe eyodwa phezu komunye ukuze imicu ye-weft ihlale iqinile phakathi kwentambo evukile engenhla nengaphansi.Ezimpambanweni zomgwaqo kuzohlale kuhlangana imicu emithathu.
Gcoba ama-laminates angalukiwe
I-scrim (i-warp eyodwa noma ephindwe kabili) i-laminated phezu kwe-nonwoven (eyenziwe ngengilazi, i-polyester noma eminye imicu).Kungenzeka ukukhiqiza ama-laminates anama-nonwovens anesisindo esisuka ku-0.44 kuya ku-5.92 oz./sq.yd.
