Ibhodi yePVC ikwasetyenziswa ngokubanzi kubomi bemihla ngemihla. Namhlanje, umenzi we- polyethylene amafutha ithatha ukuba wazi iingxaki eziqhelekileyo zebhodi ye-PVC.

1. Ukuphambuka kobuninzi be-longitudinal yebhodi ye-PVC inkulu
(1) Ulawulo lobushushu lombhobho aluzinzanga, nto leyo eyenza isantya sokunyibilika singazinzi. Iqondo lokushisa lombhobho liya kulungelelaniswa ukuze lizinzise.
(2) Ukungazinzi kwesantya se-screw kukhokelela ekungazinzini kobuninzi be-extrusion. Iiparamitha zenkqubo ye-extruder kufuneka zihlengahlengiswe ukwenza i-extrusion izinzile.
(3) Isantya sokujikeleza sekhalenda ye-roller ayizinzile, ngoko ke isantya sokujikeleza se-calender ye-roller ezintathu kufuneka silungiswe.
(4)Isantya sokutsala asizinzanga, sikhawuleza kwaye sicotha. Isantya sokutsala kufuneka sihlengahlengiswe ukuze ihambe kakuhle.
2. Ubunzima obungalinganiyo obunqamlezileyo bebhodi yePVC
(1) Uyilo lokubumba alunangqiqo kwaye ukuhamba kwe-cross-sectional fabric flow akufani, ngoko ke i-mold kufuneka iguqulwe ukwenza i-die discharge uniform.
(2) Uhlengahlengiso lwe-gap yomlomo wokufa alunangqiqo kwaye alulingani. Umsantsa phakathi kwala macala mabini kufuneka ube mncinci kancinci kunalowo uphakathi kwamacala amabini.
(3) I-gap emithathu ye-roller ye-calender yesithathu inkulu, ngoko ke umsantsa phakathi kweerola ezintathu kufuneka ufane.
(4) Ukukhethwa kobude kunye nokusetyenzwa kwe-roller ezintathu akunangqiqo. Ukuphakama okuphakathi kwendawo yomqulu kufuneka kutshintshwe ngokufanelekileyo.
3. Umphezulu webhodi yePVC urhabaxa kwaye awukhazimli
(1) Umphezulu osebenza ngerola ezintathu urhabaxa okanye uncangathi. Umphezulu wokusebenza we-roll emithathu uya kucocwa kwaye upolishwe ukwenza umphezulu uhlangabezane neemfuno ezigudileyo.
(2) Ubushushu be-roller yekhalenda buphantsi, ngoko ke ubushushu bee-roller ezintathu kufuneka bonyuswe ngokufanelekileyo.
(3) Ukuba umphezulu womlomo wokufa awugudi, umlebe wokufa kufuneka ucocwe.
(4) Ukuba isihluzo saphukile, isihluzo esitsha kufuneka sitshintshwe.
4. Kukho imigca enqamlezileyo kumphezulu wepleyiti
(1) Ukuxubana ngokungalingani kwezinto kubangela ukuguquguquka kobuninzi be-extrusion. Ukuze wenze izinto zeplastiki kakuhle kunye neyunifomu yobuninzi be-extrusion, izinto zokuxuba kufuneka zitshintshwe kwaye iiparitha zenkqubo ye-extruder kufuneka zilungiswe.
(2) Ubushushu bomphanda buguquguquka kakhulu. Jonga kwaye ulungelelanise inkqubo yokulawula ubushushu be-barrel ukuqinisekisa ukuchaneka kokulawula ubushushu.
(3) Isantya sokujikeleza se-roller ezintathu asizinzanga okanye i-roller surface ikrwelwe. Isantya se-roller ezintathu kufuneka sihlengahlengiswe ukuze siqhube kakuhle; Faka indawo yerola eyenzakeleyo okanye ulungise umphezulu werola.
(4) Isantya sokutsala asizinzile okanye uxinzelelo lwe-roller ye-traction alunelanga. Isantya sokutsala kunye noxinzelelo lwe-roller traction roller kufuneka luhlengahlengiswe ukwenza i-plate traction iqine.
5. Ipateni yobude kumphezulu wepleyiti
(1) Ukuvuleka kwesithuba somlebe wokufa kuncinci kakhulu. Kufuneka kwandiswe ngokufanelekileyo. Ukuvulwa komlomo wokufa ngokuqhelekileyo ulingana okanye ungaphantsi kancinci kunobunzima beshiti lentsimbi, eyandiswe emva kwe-extrusion kwaye yolulelwe kubukhulu obufunekayo.
(2) Ubushushu be-extrusion buphantsi kwaye iplastiki yokunyibilika imbi. Ukushisa kwe-fuselage kunye neempumlo kufuneka kwandiswe ngokufanelekileyo.
(3) Isantya sokutsala sikhawuleza kakhulu. Kufuneka ithotywe isantya ngokufanelekileyo. Isantya sokutsala kufuneka sikhawuleze kancinci kunesantya se-extrusion.
6. I-Warpage
(1) Ulawulo lwe-Calender roller lokushisa alufanelekanga, ngakumbi phakathi kunye nobushushu obuphantsi be-roller buphantsi kakhulu. Ukushisa kwe-roller kufuneka kulawulwe kuluhlu olufanelekileyo.
(2) Umphezulu wokudibana phakathi kweziphelo zimbini zepleyiti kunye nomoya mkhulu kakhulu, isantya sokupholisa sikhawuleza kakhulu, kwaye isantya sokupholisa sendawo ebhityileyo yepleyiti sikwakhawuleza. Xa usenza, ipleyiti igoba kwindawo yokuqala yokupholisa, okubangela uxinzelelo lwangaphakathi. Ukuze kuncitshiswe uxinzelelo lwangaphakathi lokubumba, kufuneka lupholile ngokulinganayo ukuze kuncitshiswe idrafti.
7. Amaqamza
(1) Isixhobo ekrwada simanzi kwaye isiqulatho sokufuma singaphezulu komgangatho. Izinto eziphathekayo kufuneka zigcinwe ukufuma okuphantsi.
(2) Ubushushu be-fuselage kunye nempumlo buphezulu kakhulu, okubangela ukubola kwezinto. Ubushushu bokusebenza kufuneka buncitshiswe ngokufanelekileyo.
8. Imigca emnyama okanye eguquguqukayo kunye namabala kumphezulu
(1) Ubushushu bentloko buphezulu kakhulu kwaye izinto eziphathekayo zishushu kwaye zibolile. Ubushushu bentloko kufuneka buncitshiswe ngokufanelekileyo.
(2) Kukho i-angle efileyo entloko, kwaye izinto ezimileyo zibolile. Intloko yomatshini kufuneka icocwe ukuphelisa i-angle efileyo.
(3) Kukho ukungcola okuvimba entloko, okubangela ukubola kwezinto ezimileyo. Intloko yomatshini kufuneka icocwe ukususa ukungcola.
(4) Kukho iimvula kumphezulu wekhalenda ye-roller ezintathu. Umphezulu we-roller kufuneka ucocwe ukuze ususe ama-volatiles.
9. Indawo engaphezulu
(1) Ubushushu bomqulu osezantsi wekhalenda ye-roller emithathu iphezulu kakhulu, kwaye ipleyiti ibambelela kumphezulu we-roller. Ukushisa kwe-roll ephantsi kufuneka kuncitshiswe ngokufanelekileyo.

10. Indawo ebandayo kumphezulu
(1) Iqondo lobushushu lerola yekhalenda yesithathu iphantsi kakhulu. Ubushushu be-roller kufuneka bonyuswe ngokufanelekileyo.
(2) Kukho iwax kumphezulu wecalenda yerola ezintathu. Umphezulu we-roll kufuneka ucocwe.
