PVC ban ruwa bututu:
(1) PVC ban ruwa bututu yana da kyau kwarai acid juriya, alkali juriya da kuma lalata juriya, wanda shi ne sosai dace da sinadaran masana'antu.Katangar bangon bututun ban ruwa na PVC yana da santsi.Juriyar ruwan ƙanƙara ce, kuma ƙarancin ƙarancin sa shine kawai 0.009, wanda ya yi ƙasa da sauran bututu.Ƙarƙashin ƙimar guda ɗaya, ana iya rage diamita na bututu.Rashin juriya na ruwa, juriya na waje da juriya na tasiri na bututun ban ruwa na PVC suna da girma sosai, wanda ya dace da aikin injiniya na bututu a ƙarƙashin yanayi daban-daban.Yana da arha kuma ana amfani dashi ko'ina.
(2) Bututun ban ruwa na PVC na iya bin tsarin girma na amfanin gona don gane ban ruwa na zamani.Za a iya zaɓar amfani da ruwa na ban ruwa bisa ga ƙayyadaddun abun ciki na amfanin gona da ƙasa.
(3) PVC ban ruwa bututu ne mafi cikakken za a iya dogara ne a kan halaye na yanzu kweather cimma daidai ruwa samar da taki zuwa tushen amfanin gona ban ruwa dabaru.Wannan na iya rage aikin hannu.
(4) Bututun ban ruwa na PVC na iya jigilar ruwa mai ma'ana daidai gwargwado bisa ga buƙatun girma na amfanin gona, wanda zai iya tabbatar da ingantaccen ban ruwa na amfanin gona a kan kari kuma ya dace da kafa harsashi mai ƙarfi don haɓaka yawan amfanin gona.
(5) Ana amfani da bututun ban ruwa sosai a cikin birni da ƙauye na cikin gida da waje na ruwa, haɓakar ruwa na karkara, ban ruwa na gonaki, bututun watsa bututun gishiri da masana'antar sinadarai, isar da ruwa na masana'antar aquaculture, iskar ma'adinai, samar da ruwa da magudanar ruwa, gyaran shimfidar wuri sprinkler. ban ruwa da sauran ayyuka manya da kanana.
Polyvinyl Chloride (PVC) resin thermoplastic ne na linzamin da aka samar ta hanyar polymerization na vinyl chloride monomer.Saboda bambancin albarkatun kasa, akwai hanyoyi guda biyu na hada vinyl chloride monomer calcium carbide tsari da kuma tsarin man fetur.Sinopec PVC ta ɗauki tsarin dakatarwa guda biyu, bi da bi daga Kamfanin Sin-Etsu Chemical Company da Kamfanin Oxy Vinyl na Amurka.Samfurin yana da kyakkyawan juriya na lalata sinadarai, kyawawan kayan rufewar lantarki da kwanciyar hankali mai kyau.Tare da babban abun ciki na chlorine, kayan aiki yana da kyaun kashe wuta da kaddarorin kashe kansa.PVC yana da sauƙin aiwatarwa ta hanyar extrusion, gyare-gyaren allura, calending, busa gyare-gyare, damfara, gyare-gyaren simintin gyare-gyare da gyare-gyaren thermal, da dai sauransu.
