PVC-O umbhobho wokwenza umgca umatshini

Imishini yokwenza imibhobho ye-PVC-O (ejoliswe kwi-PVC) yenzelwe ngokukodwa ukuvelisa imibhobho ye-PVC-O, eyaziwayo ngokwamandla abo aphuculweyo, ukuqina, kunye nokuxhathisa impembelelo kunye noxinzelelo. Imibhobho ye-PVC-O isetyenziswa ngokubanzi kwizicelo ezahlukeneyo, kubandakanywa unikezelo lwamanzi, ukunkcenkceshela, kunye neenkqubo zombhobho ongaphantsi komhlaba. Nanga amacandelo aphambili afunyanwa kumatshini wokwenza umbhobho wePVC-O:

1.I-Extruder: I-extruder yeyona nto iphambili yomatshini onyibilikayo kunye ne-homogenizes i-resin ye-PVC. Iqulathe umphanda wokufudumeza, isikrufu, kunye nenjini. I-resin ye-PVC ifakwe kwi-extruder, apho ifudunyezwa khona, inyibilika, kwaye inyanzeliswe ngesikrufu ukwenza umjelo oqhubekayo otyhidiweyo wePVC.

I-2.Die Head: Intloko ye-die inoxanduva lokubumba i-PVC etyhidiweyo kwiprofayili yombhobho oyifunayo. Kwimeko ye-PVC-O imibhobho, intloko yokufa yenzelwe ngokukodwa ukudala isakhiwo se-molecularly oriented ngaphakathi kumbhobho. Le nkqubo yokuqhelanisa iphucula iimpawu zomatshini wombhobho, okwenza ibe yomelele kwaye ixhathise uxinzelelo.

I-3.I-Cooling kunye ne-Sizing System: Emva kokuphuma kwintloko yokufa, umbhobho we-PVC uhamba ngenkqubo yokupholisa kunye nokulinganisa. Le nkqubo ipholisa ngokukhawuleza i-PVC etyhidiweyo ukuyiqinisa kwaye igcine imilinganiselo efunekayo kunye nokumila kombhobho. Isenokuquka iitanki zamanzi, imikhono yokucoca, okanye ezinye iindlela zokupholisa.

I-4.Inkqubo yokuqhelaniswa nayo: Inkqubo yokuqhelaniswa yinxalenye ebalulekileyo kumatshini wokwenza umbhobho wePVC-O. Isebenza ukolula okulawulwayo okanye ukwandiswa kumbhobho ukuphembelela ukuqhelaniswa nemolekyuli. Le nkqubo ilungelelanisa iamolekyu ze-PVC, okukhokelela ekuphuculeni amandla kunye neempawu zokusebenza kombhobho.

I-5.Inkqubo yokukhupha i-Haul-off: Inkqubo yokukhupha iqulethe iingoma ezinjenge-caterpillar okanye amabhande abamba umbhobho kwaye ayitsale ngesantya esiqhubekayo. Le nkqubo iqinisekisa ukufana kunye nokuthintela ukunweba okanye ukuguqulwa kombhobho ngexesha lenkqubo yokuvelisa.

6.Ukusika kunye nokupakishwa: Emva kokuba umbhobho wePVC-O ukhutshiwe, upholile, kwaye ulungelelaniswe, unqunywe ubude obufunwayo usebenzisa isixhobo sokusika okanye isarha. Amacandelo emibhobho esikiweyo emva koko apakishwe okanye ahlanganiswe ukuze aqhubeke nokusebenza okanye ukupakishwa.

I-7.Inkqubo yokulawula: Oomatshini bokwenza umbhobho we-PVC-O baxhotyiswe ngenkqubo yokulawula ebeka iliso kwaye ilawule iiparitha ezahlukeneyo ezifana nobushushu, uxinzelelo, isantya, kunye nemilinganiselo yombhobho. Le nkqubo iqinisekisa umgangatho ongaguqukiyo kunye nemveliso esebenzayo.

Kubalulekile ukuqaphela ukuba uqwalaselo oluthile kunye neempawu zomatshini wokwenza umbhobho wePVC-O unokwahluka ngokuxhomekeke kumenzi kunye nomthamo ofunekayo wemveliso. Oomatshini abakwizinga eliphezulu banokubandakanya iimpawu ezongezelelweyo ezifana nezixhobo zokuvavanya ezingaphakathi, iinkqubo ezizenzekelayo, kunye neenkqubo zokulawula umgangatho ukunyusa umgangatho kunye nokusebenza kakuhle kwemveliso yombhobho wePVC-O.
