Huremu hwegiramu hunoenderana nehukobvu hwe geotextile hwakadii?
Kurema kwegeotextileinosiyana kubva pa100g kusvika 1000g pa square mita. Sezvo iri jira risina kurukwa rinogadzirwa nekushandisa needling inodzokororwa, hazvigoneke kuona kuti rakakora sei nekubata nemaoko, uye mudziyo wekuyera ukobvu hwejira risina kurukwa unofanirwa kushandiswa kuriyera.
Saka magiramu zana ehukobvu hwejira risina kurukwa hunorema sei?
Mhinduro yacho haiverengeki. Tinokwanisa chete zvichienderana nezviratidzo zvehunyanzvi zve geotextile kuona machira ayo asina kurukwa e100 g, uye machira mapfupi ewaya neshinda, kunyangwe ese ari magiramu 100, asi ukobvu hwakasiyana, ukobvu hwejira rewaya pfupi hwe100 g mu 0.9 mm (millimeter), nepo shinda iri mu0.8 mm, hongu, pachava nekukanganisa kwe2% kusvika 3%, nekuti mhando dzakasiyana dzemichina nemabasa etekinoroji dzakasiyana, saka hatigone kudzivirira kuvapo kwezvikanganiso.
Ma geotextiles asina kurukwa anogona kudziya here?
Nekutijira risina kurukwaYakagadzirwa nefiber yepolyester yakasimba uye inodzivirira kukwegura kana polypropylene uye machipisi epolyester sezvinhu zvakagadzirwa kuburikidza nekugadziriswa kwakakosha, saka ine simba rakanaka rekudzivirira ngura, inodzivirira acid nealkali, simba rekupwanyika uye inodzivirira chando kunyunguduka.
Semuenzaniso, mukuvaka sisitimu yekudzivirira kupisa inodziya mugreenhouse, jira risina kurukwa rinogona kutsiva zvachose kushandiswa kwefelt, rakaiswa nyore, kuchengetedza nguva nesimba; Panyaya yekudzivirira denga, sisitimu yekudzivirira denga yechinyakare ndeyekuvaka jira rekuvaka mushure mekunge jira rakaderera radzikiswa, wobva wadira kongiri ine mhepo pamusoro pejira rekuvaka, wobva waisa asbestos insulation layer, wobva waisa jira risingapindi mvura nejira risina kurukwa pamusoro pejira.
Kusangana kwakadaro kunoita kuti jira rionekwe, pasi pechiedza chenguva refu chemwaranzi ye ultraviolet, kwakapfupisa hupenyu hwaro; Nekufambira mberi kwesainzi netekinoroji, vanhu vanogara vachigadzira hunyanzvi hutsva, vakagadzira chimiro chitsva chekudzivirira denga: nzira yekudzivirira inversion system, nzira iyi iri uye nzira yechinyakare yekudzivirira inversion, ichave pamusoro pechikamu chisingapindi mvura uye geotextile yakaiswa muchikamu chekudzivirira asbestos chefuro chiri pasi, inoita kuti jira risaonekwe pasi pevhu, nokudaro rinowedzera hupenyu hwebasa uye rinoita kuti muviri mukuru wekudzivirira insulation uve wakasimba, wakavimbika, uye unochengetedza mutengo wemutengo weinjiniya.
