Amakhasimende amaningi awacacile mayelana nemibono yokungabi nobuthi kanye nokuvikelwa kwemvelo kwamapayipi epulasitiki e-PVC, futhi acabanga ukuthi okungewona ubuthi kuyimvelo.Eqinisweni, akunjalo.Ukuze siqonde ngokujulile le mibono emibili, kufanele siqale sihlukanise izinto ezingavuthiwe kanye nokusetshenziswa kwamapayipi.
Ukwethulwa kwepayipi lepulasitiki le-PVC ukusebenzela umphakathi futhi ulisebenzise ekuphileni kwabantu kwansuku zonke, kodwa kukhawulelwe ekushayeni phansi, izimbali, izingadi, izesekeli zemishini, amashethi, njll. Ekuqaleni, abasebenzi ezindaweni zokwakha amanzi okulethwa.Kusukela kulezi zici, lezo ezingathintana nabantu isikhathi eside kufanele zithathwe njengezingenabo ubuthi noma azinakwa, kodwa lokhu kukhawulelwe ezintweni zokusetshenziswa zangempela.
Umqondo wokuvikelwa kwemvelo ubanzi uma kuqhathaniswa, vele uchofoze ku-Baidu, lapha ukuze ukhulume ngomqondo wokuvikelwa kwemvelo kwamapayipi epulasitiki e-PVC, okusho ukuthi izinto ezikhuphuka ngemva kokuwohloka kwamapayipi e-PVC ngeke zibangele ukulimala emzimbeni womuntu.I-PVC iyi-polyethylene, okuyi-resin powder.Izingxenye ezikhiqiza izinto eziyingozi epayipini zivela kwenye impahla eluhlaza eyenza ipayipi, i-butyl ester, ipharafini ene-chlorinated, (noma i-octyl ester, p-benzene, TOTM).Amapayipi avamile ngokuvamile enziwe nge-PVC, i-butyl ester, i-chlorine Yakhiwe nge-wax kapharafini nezinye izinto ezisizayo.I-butyl ester kanye nopharafini akuvamisile ukuthi kwehlise i-benzene uma izinga lokushisa lingaphansi kuka-45 degrees Celsius, ngakho kuphephile futhi akunabo ubuthi.
Ukuvikelwa kwemvelo kusho ukuthi amapayipi e-PVC aphumelele ukuhlolwa kwezikhungo ezigunyaziwe ngaphandle kwe-phthalate precipitation angasetshenziselwa amapayipi amanzi okuphuza futhi ahlulelwe ukuthi ahambisana nemvelo.Lesi sidingo siqinile, futhi kusetshenziswa izinto ezingavuthiwe kuphela ezivikela imvelo.
Ngakho-ke, lapho ukhetha i-hose, zama ukusebenzisa okungezona ubuthi noma imvelo ukuze usetshenziswe ekhaya.Intengo ayikhululekile kuphela ngesikhathi sokukhokha, futhi ohlelweni lokusebenzisa umkhiqizo, kukhona injabulo ehambisanayo, futhi ukusetshenziswa kwe-tube akukhathazeki.
