Iingenelo ezininzi zeevalvu zebhola zePVC zizenza zibe lukhetho oluhle kakhulu kwiintlobo ngeentlobo zezicelo. Kukho izinto ezithile ekufuneka ziqwalaselwe xa ugqiba ekubeni uthenge ivalvu yebhola, ingakumbi ivalvuIvalvu yebhola yePVCNangona i-PVC ikwazi ukumelana neemeko ezahlukeneyo, ukufana okufanelekileyo phakathi kwevalvu kunye nokusetyenziswa kwayo kubaluleke kakhulu xa ukhetha ivalvu yebhola yePVC.

Ukukhetha ivalvu yebhola yePVC
uyilo lomngxunya
Nangona uhlobo lwe-PVC oluneendlela ezimbini luqheleke kakhulu, kukho ezinye iindlela zoyilo lwemingxunya ezinokunceda ukuphucula ukusebenza kakuhle kokusetyenziswa. Uyilo lwe-bore oluneendlela ezintathu luquka ulwakhiwo lwe-T-port kunye ne-L-port kwiindawo zokusetyenziswa apho ukuhamba kolwelo kuxubaniswa, kusasazwa, kwaye kujikeleziswa. Olu yilo lwemingxunya luluncedo kakhulu kwiintlobo ezininzi zolwelo kunye neentlobo ezahlukeneyo zokuhamba.

ukuqonda imidiya
Esinye sezizathu zokuphuhliswa kweevalvu zebhola zePVC ngeminyaka yoo-1950 yayiziimedia ezazifuna ukuphathwa ngendlela ekhethekileyo. Iivalvu zebhola zePVC zifanelekile kwiimedia ezibolayo ezifana namanzi anetyuwa, ii-asidi, ii-alkali, izisombululo zetyuwa kunye nezinyibilikisi zendalo, ezinokonakalisa ezinye izinto. Ukuqonda iimpawu zemedia yinto ebalulekileyo kwinkqubo yokukhetha.

I-Coefficient yobushushu
Ubushushu buyinto ephambili kwizicelo ezininzi zokwenziwa kwaye kufuneka buqwalaselwe ngononophelo xa kukhethwa ivalvu yebhola yePVC. Ulwakhiwo lweekhemikhali zezinto zePVC luyinto ekhokelayo xa kukhethwa ivalvu yebhola yePVC, njengoko iPVC ithambekele ekuwohlokeni nasekutshintsheni phantsi kweemeko ezithile.

iziphumo zoxinzelelo
Njengobushushu, uxinzelelo lunokuchaphazela kakhulu ukufaneleka kwe-Ivalvu yebhola yePVCkwesicelo. Kwimeko enjalo, ulwakhiwo lwe-PVC lunokuba yinto ethatha isigqibo.

ukuququmbela
Ivalvu yebhola yePVC okanye yepolyvinyl chloride yivalvu yeplastiki evaliweyo enebhola ejikelezayo enomngxuma othintela ukuhamba kwemidiya ngokujika ibhola ijika ngekota.
Ingundoqo yeIvalvu yebhola yePVCyibhola ejikelezayo, ebizwa ngokuba yibhola ejikelezayo. Isiqu esingaphezulu kwebhola yindlela ejika ibhola, enokwenziwa ngesandla okanye ngokuzenzekelayo, kuxhomekeke kuyilo lwevalvu.
Iindidi ezahlukeneyo zeevalvu zebhola zePVC zenzelwe ukuhlangabezana nezicelo ezithile. Zihlulwe ngokwenani leendawo zokungena, uhlobo lwesihlalo, ukuhlanganiswa komzimba, iindlela zebhola kunye nobukhulu bebhore.
Izinto ezisisiseko zevalvu yebhola yePVC yipolyvinyl chloride, eyi-vinyl resin. Igama elithi PVC libhekisa kwizinto ezahlukeneyo zePVC ezinamandla, iimpawu kunye neempawu ezahlukeneyo.
Ukusetyenziswa okuqhelekileyo kweevalvu zebhola zePVC kukusika okanye ukudibanisa imidiya kwimibhobho kunye nokulawula ulwelo kunye nokulawula.
