I-PVC Pipe Ifomu Eligcwele: Incazelo, Izinhlobo, Amazinga Nezicelo

Noma ngabe ungumsabalalisi, usonkontileka, noma unjiniyela ohlonza izinto zamapayipi, ukuqonda ifomu eligcwele lepayipi le-PVC kanye nemithelela yalo ebonakalayo kukusiza ukuthi wenze izinqumo ezingcono zokuhlinzekwa kwamanzi, ukuthuthwa kwamanzi, namaphrojekthi ezimboni. Lo mhlahlandlela uhlanganisa incazelo ye-PVC, ukuthi ihluke kanjani ku-UPVC ne-CPVC, amazinga ayibusayo, nokuthi yini okufanele uyihlole ngaphambi kokuthenga.

Liyini Ifomu Eligcwele Lepayipi le-PVC?

I-PVC imele i-Polyvinyl Chloride. Ipayipi le-PVC limane lisho ipayipi elenziwe ngale nto - i-polymer yokwenziwa ye-thermoplastic ekhiqizwa nge-polymerizing vinyl chloride monomer (VCM).

I-PVC ingenziwa njengeqinile noma eguquguqukayo. I-PVC eqinile isetshenziselwa amapayipi, okokufakwayo, nama-valve ngoba ibamba ukuma kwayo kanye nesilinganiso sokucindezela ngaphansi komthwalo; I-PVC eguquguqukayo , equkethe ama-plasticizers, ingena emikhiqizweni efana ne-cable insulation namapayipi. Emapayipini, cishe kuhlale kuyifomu eliqinile — ngakho-ke 'ipayipi le-PVC' alilona igama lekhemikhali elihlukile, ipayipi nje elakhiwe ngenhlanganisela ye-PVC.

I-PVC vs i-PVC vs CPVC

Ezimakethe eziningi, 'ipayipi le-PVC' selivele lisho ifomu le-PVC eliqinile elisetshenziselwa ukucindezela kanye nezinhlelo zokudonsa amanzi. I-CPVC iyinto ehlukile, eneklorini ekhethwa lapho uketshezi lushisa kakhulu kunalokho okungaphathwa yi-PVC.

Ukwakhiwa kanye Nenqubo Yokukhiqiza

Inhlanganisela yepayipi le-PVC ingaphezu nje kwe-resin. Ngokuvamile kuhlanganisa:

• I-PVC resin (i-polymer eyisisekelo, ngokuvamile i-80%+ yengxube)

• Ama-Stabilizers - vikela ekushiseni nasekuwohlokeni kwe-UV

• Izinto zokuthambisa — aid processing ngesikhathi extrusion

• Izilungisi zomthelela - zithuthukisa ukumelana nokuqhekeka

• Izingulube — setha umbala ophelile

Ukukhiqiza kulandela ukulandelana okungaguquki: i-chlorination ye-ethylene ikhiqiza i-vinyl chloride monomer, eyenziwa nge-polymerized ibe yi-PVC resin; i-resin ihlanganiswe nezithasiselo, iyancibilika, futhi ikhishwe ngepayipi lokufa; ipayipi libe selilinganiswa, lipholiswe emathangini amanzi, lisikwe libe lide, futhi lihlolwe izinga ukuze kutholwe ubukhulu, ukumelana nomfutho, futhi libe isicaba ngaphambi kokuba liphume efektri. Ukuthola izilinganiso okungaguquki kanye nezilinganiso ezinembile zokuhlanganisa yizo ezihlukanisa ipayipi elilinganiselwe amashumi eminyaka esevisi nalelo elihlulekayo kusenesikhathi - ukulawula ikhwalithi yomkhiqizi kubaluleke kakhulu njenge-polymer ngokwayo.

Izinhlobo zamapayipi e-PVC

Ngesicelo:

• Ipayipi le-UPVC - liqinile, alikwazi ukugqwala, ukuze lisetshenziswe amanzi kanye nokusetshenziswa kwezimboni okuvamile

• Ipayipi le-CPVC — lamanzi ashisayo noketshezi oluhambisana nezinga lokushisa eliphezulu

• Ipayipi lokucindezela le-PVC — kumasistimu acindezelwe, likalwe ngoSheduli noma nge-SDR

• Ipayipi le-PVC lokudonsa amanzi - lamanzi angcolile namasistimu endle

• Ipayipi lepayipi le-PVC - livikela izintambo zikagesi (hhayi indawo yepayipi lokucindezela)

• Sula ipayipi le-PVC - ivumela ukuqapha okubonakalayo kokugeleza kwamalebhu nemigqa yenqubo

Ngezinga lamazwe ngamazwe: Ubukhulu, izilinganiso zokucindezela, nezindlela zokuhlanganisa ziyahlukahluka ngendawo, ngakho ipayipi ngokuvamile likhiqizwa kwelinye lamazinga amathathu:

• I-DIN - ivamile kulo lonke elaseYurophu, eMpumalanga Ephakathi, nase-Afrika; kucaciswe ububanzi obungaphandle kanye nesilinganiso se-PN (isb., PN10, PN16)

• I-ASTM - ikhonya eNyakatho Melika nasengxenyeni enkulu yeLatin America nase-Asia; I-ASTM D1785 ihlanganisa ipayipi le-Schedule 40/80/120, i-ASTM D2241 ihlanganisa ipayipi elilinganiselwe le-SDR, futhi i-ASTM F441 ihlanganisa ipayipi le-CPVC

• I-JIS — indinganiso yochungechunge lwe-VP yonkana e-Japan kanye nezingxenye ze-Southeast Asia, enobubanzi bayo kanye nokuhlukaniswa kwengcindezi

Ipayipi eline-DIN-dimensional ngeke liluke noma lishise i-solvent ngendlela efanele ngokufakwa kwe-ASTM, ngakho qinisekisa izinga elidingekayo ngaphambi koku-oda — ngokufanelekile lisuka kumkhiqizi okhiqiza kuzo zontathu kunokuthi alungise umugqa owodwa. (I-Huasheng Pipe ikhiqiza I-DIN ejwayelekile, I-ASTM D1785 , kanye Ipayipi le-PVC le-JIS VP .)

Izakhiwo Nezinzuzo Ezibalulekile

• Ukumelana nokugqwala - I-PVC ayigqwali, futhi imelana nama-asidi amaningi, ama-alkali, nezixazululo zikasawoti (ukuhambisana kwamakhemikhali kusafanele kuqinisekiswe ngokwesilinganiso kanye nokugxila)

• I-Lightweight - kulula futhi kushibhile ukuyihambisa, ukuyiphatha, nokuyifaka kunepayipi lensimbi

• I-Smooth bore - inciphisa ukulahleka kokungqubuzana nokwakheka kwesikali
