I. Iimpawu:

1. Umbhobho we-upvc, owaziwa ngokuba ngumbhobho we-polyvinyl chloride oqinileyo, umbhobho we-u-pvc, luhlobo lokumelana nokugqwala okuqinileyo, i-asidi, i-alkali yetyuwa yetyuwa ephakathi kokuxhathisa ukhukuliseko, ubunzima obulula, amandla athile omatshini, iimeko ezilungileyo zehydraulic, ukufakwa okulula, kodwa kulula ukuguga, ukumelana nobushushu obuphezulu, kodwa ayikwazi ukumelana nefuthe, ilungele inkqubo yamanzi asekhaya, uqhagamshelo lombhobho we-DN50, i-DN65 ngaphezu kodibaniso lwendandatho.

2. Umbhobho we-pvc-u, owaziwa ngokuba ngumbhobho we-polyvinyl chloride onzima, luhlobo olutsha lombhobho wokukhupha amanzi kunye nodonga lwangaphakathi olugudileyo kunye nokuqiniswa ngokuthe nkqo eludongeni olungaphandle.Ilungele inkqubo yokuhambisa amanzi kuluntu kwaye ithatha i-"T" uhlobo lwe-rubber interface.

Eyesibini, ukhetho lwemathiriyeli yoyilo:

I-1, i-PVC-U isetyenziselwa ukwakhiwa kwamanzi kunye ne-drainage, ukukhanya kunye nexesha elide, umbala omhle, oqaqambileyo kunye ogudileyo, ukuxhathisa ukuguga, ubomi obude benkonzo, iipropati ezibalaseleyo zomzimba kunye neekhemikhali, ukuxhathisa ukubola kweekhemikhali, amandla anempembelelo ephezulu.

2. ityhubhu ye-UPVC inomkhenkce ombi kunye nokumelana nobushushu.Ukuxhathisa ukoma okuhle, ukuxhathisa okuqinileyo komhlwa, ukuxhathisa ulwelo oluphantsi, amandla omatshini aphezulu, impilo engenatyhefu, ukuxinana kwamanzi okulungileyo, umbhobho wePVC ulungele imibhobho yocingo kunye nogutyulo, kunye namandla ofakelo lombhobho omkhulu ongaphezulu, njengokupholisa isityalo sombane. inqaba.

Eyesithathu, i-engile yokwakha:

I-1, i-PVC-U isetyenziselwa ubukhulu becala ukwakhiwa kwamanzi kunye ne-drainage, umbhobho ofakwe ngaphakathi, indlela yokwakha ephambili yokunyibilika okutshisayo, kunye ne-adhesive, ukwakhiwa kwebusika akulula.

2. I-UPVC isetyenziselwa ukwakha unikezelo lwamanzi kunye ne-drainage kunye nemibhobho yogutyulo.Inokuthi ithathe indawo yemibhobho yentsimbi eqhelekileyo kunye nemibhobho enamazimba.
