Chigoba cholumikizidwa chimaoneka ngati gridi kapena latisi. Ndi nsalu yolimbitsa yotsika mtengo yopangidwa ndi ulusi wopitilira muyeso wopangidwa ndi maukonde otseguka. Njira yopangira chigoba cholumikizidwa imagwirizanitsa ulusi wosalukidwa pamodzi, ndikuwonjezera chigobacho ndi mawonekedwe apadera.
Kulimba kwambiri, Kusinthasintha, Mphamvu yokoka, Kuchepa pang'ono, Kutalikirana pang'ono, Kuletsa moto, Kusalowa madzi, Kusapsa ndi dzimbiri, Kutseka kutentha, Kudzimamatira, Kusunga epoxy-resin, Kuwonongeka, Kubwezeretsanso ndi zina zotero.
Mthunzi wa tarpaulin wa mafakitale umagwiritsidwa ntchito m'mafakitale kuteteza zipangizo zopangira mafakitale ndi zinthu zomalizidwa za mafakitale ku nyengo ndi chinyezi kuti zisawonongeke ndi dzimbiri. Zimathandizanso kunyamula ntchito zathu zamafakitale pophimba malo ogwirira ntchito.
Tarpaulin kapena tarp ndi chinsalu chachikulu chopangidwa ndi zinthu zolimba, zosinthasintha, zosalowa madzi kapena zosalowa madzi, nthawi zambiri nsalu monga canvas kapena polyester yokutidwa ndi polyurethane, kapena zopangidwa ndi pulasitiki monga polythylene. Tarpaulin nthawi zambiri amakhala ndi ma grommets olimba m'makona ndi m'mbali kuti apange malo olumikizira chingwe, zomwe zimathandiza kuti zimangidwe kapena kuimika.
Matayala amakono otsika mtengo amapangidwa ndi polyethylene yolukidwa; nsalu iyi imagwirizana kwambiri ndi matayala kotero kuti nthawi zina imadziwika kuti polytarp.
Ma tarpaulin amagwiritsidwa ntchito m'njira zambiri kuteteza anthu ndi zinthu ku mphepo, mvula, ndi kuwala kwa dzuwa. Amagwiritsidwa ntchito panthawi yomanga kapena pambuyo pa ngozi kuti ateteze nyumba zomwe zamangidwa pang'ono kapena zowonongeka, kuti apewe chisokonezo panthawi yopaka utoto ndi zochitika zina zofanana, komanso kuti asunge ndikusonkhanitsa zinyalala. Amagwiritsidwa ntchito kuteteza magalimoto ambiri otseguka ndi magaleta, kuti milu yamatabwa ikhale youma, komanso kuti azitha kukhala m'malo obisalamo monga mahema kapena nyumba zina zakanthawi.
Tayala yokhala ndi mabowo
Ma tarpaulin amagwiritsidwanso ntchito posindikiza malonda, makamaka pa zikwangwani. Ma tarpaulin okhala ndi mabowo nthawi zambiri amagwiritsidwa ntchito potsatsa malonda apakatikati mpaka akulu, kapena kuteteza ma scaffolding; cholinga cha mabowowo (kuyambira 20% mpaka 70%) ndikuchepetsa kufooka kwa mphepo.
Ma tarpaulini a polyethylene atsimikiziranso kukhala gwero lodziwika bwino pamene pakufunika nsalu yotsika mtengo komanso yosalowa madzi. Omanga maboti ambiri osadziwa bwino ntchito amagwiritsa ntchito ma tarpaulini a polyethylene popanga ma tarpaulini awo, chifukwa ndi otsika mtengo komanso osavuta kugwiritsa ntchito. Ndi tepi yomatira yoyenera, n'zotheka kupanga tarpaulini yothandiza pa boti laling'ono popanda kusoka.
Ma tarps apulasitiki nthawi zina amagwiritsidwa ntchito ngati zipangizo zomangira m'madera a anthu aku North America. Ma tarps opangidwa ndi ma tarps amadziwika kuti ma tarps.
Tala ya polythylene ("polytarp") si nsalu yachikhalidwe, koma ndi laminate yopangidwa ndi nsalu yolukidwa ndi pepala. Pakati pake palukidwa momasuka kuchokera ku zidutswa za pulasitiki ya polyethylene, ndi mapepala a chinthu chomwecho omangiriridwa pamwamba. Izi zimapanga nsalu yofanana ndi nsalu yomwe imakana kutambasuka bwino mbali zonse ndipo siimadzi. Mapepala akhoza kukhala a polyethylene yotsika kwambiri (LDPE) kapena polyethylene yotsika kwambiri (HDPE). Akamachiritsidwa ku kuwala kwa ultraviolet, matala awa amatha kukhala kwa zaka zambiri akakhala ndi nyengo, koma zinthu zomwe sizili ndi UV zimasanduka zofooka mwachangu ndikutaya mphamvu ndi kukana madzi ngati zitakhala ndi dzuwa.
Nthawi zonse timafunafuna ogwirizana nawo atsopano omwe akufuna kufufuza zinthu zathu ndikupanga china chatsopano pamodzi. Ma scrims athu amatha kuwagwiritsa ntchito m'njira zosiyanasiyana. Takulandirani ku Shanghai Ruifiber, maofesi ndi malo ogwirira ntchito, mwachangu kwambiri.—www.rfiber-laidscrim.com
