Amapayipi, njengamapayipi e-PVC, angenziwa kusetshenziswa cishe okufanayo nalawo asetshenziswa kuma-dies e-extrusion efilimu eqhumile.

Ingcindezi enhle ingafakwa ezimbotsheni zangaphakathi kulo lonke ugibe, noma ingcindezi engafuneki ingafakwa kububanzi bomphezulu nge-vacuum sizer ukuqinisekisa ukuthi izilinganiso zokuvala zifanelekile.

Ama-lumens noma izimbobo ezengeziwe zingafakwa ngokufaka ama-mandrel angaphakathi afanele endaweni.

Izinto zikagesi zamashubhu ezinezingqimba eziningi zingase zigcinwe embonini yezimoto, amapayipi, kanye nebhizinisi lokushisa kanye nemakethe yokupakisha.

Izinto Eziyisisekelo
I-resin esetshenziswa kabanzi ekukhiqizweni kwamapayipi yizinto zepulasitiki ezifana ne-PE, i-PVC.

Izinto zokukhiqiza amapayipi akho zingadinga ukuqinisekiswa. Isibonelo, abakhiqizi abaningi bamapayipi basebenzisa i-PVC.

I-resin ayizweli kakhulu ekushiseni futhi ngaphansi kwezidingo zokucubungula ezivamile, i-viscosity ephezulu, ngakho ayikwazi ukucutshungulwa. Idinga ukuhlanganiswa.

Ukuhlanganiswa kwe-PVC kuwukucubungula lapho izithasiselo zixutshwa ne-base resin ukuze kutholakale ingxube efanayo.

Izithasiselo zifakiwe ukuze kuthuthukiswe amakhono enqubo noma kuthuthukiswe ukusebenza komkhiqizo.

Inqubo Yenqubo Yamapayipi

Okokuqala, ama-plasticizer asetshenziselwa ukukhiqiza i-resin ejiyile, ukunciphisa i-viscosity ngakho-ke inqubo ye-PVC ibe lula.

Iziqinisi zokushisa bezilindele ukuvikela ekuwohlokeni kokushisa emazingeni okushisa enqubo. Ukuwohloka kuhilela ukuthuthukiswa kanye nokuphulukiswa kombala we-HCL. Manje iziqinisi ezivamile zibikezelwa.

Izinto zokugcoba zihlose ukunciphisa ukungqubuzana ngesikhathi sokucubungula okungase kuholele ekuwohlokeni. Nazi izinhlobo ezimbili zokugcoba ezisetshenziswayo, okungaphakathi nangaphandle. Ukunciphisa izindleko kanye nokuthuthukiswa kwezingxenye zemishini yazo zonke izimpahla kufaka phakathi izigcwalisi kanye nokuqinisa. Zombili zikhulisa ukuqina, ubulukhuni, ukujiya kanye nokuphelelwa yisikhathi komlilo.

I-Die Yokukhipha Amapayipi:
Umsebenzi wedayi yokukhipha ugesi uzoba ukukhiqiza izinto ezincibilikisiwe ezinikezwa yintambo yesikulufu zibe yisigaba esidingekayo.

Uhlelo Lokupholisa:
Kuyo yonke isayizi kanye nepayipi kubanda. Ukupholisa kuzokwenzeka ngokufafaza amanzi phezulu kwepayipi. Leli nani lokupholisa kulo lonke i-PE liphezulu kakhulu uma liqhathaniswa ne-PVC.

Umshini Wokususa:
Imishini yokudonsa iqinisekisa usayizi wamapayipi ofanayo. Ama-pullers ayizinhlobo zama-caterpillar zalolu hlobo lwamasondo anyakazayo. Ukushintshashintsha kwezinga likagesi likamagnetic noma lika-elekthronikhi kulawula izinga lokudonsa.

Uhlelo Lokulawula:
Banikeza ukulinganisa okuzenzakalelayo kanye nokulawula usayizi wepayipi. Ngenye indlela amandla aleli payipi ayalinganiswa. Liseduze nokujula. Iphuzu lokuzwa lihamba lizungeze ipayipi, liveze ngokushesha nje lapho ipayipi seliphumile endaweni ezungezile ngakho-ke uma ngokuvamile likhuluphele noma lilula kakhulu.

Izisetshenziswa Zokusika:
Izicucu ezikhethekile zihlose ukunciphisa i-vinyl ibe yi-span. Futhi imishini yokusika ezenzakalelayo nayo ayisetshenziswa kahle. Okwamanje, zihamba nepayipi elizosikwa ngemva kokulisika ukuze lithathwe kanye nelinye ipayipi.
