Ekwakhiweni kwanamuhla, ubunjiniyela bakamasipala, nezinkambu eziningi zezimboni, amapayipi e-PVC adlala indima ebaluleke kakhulu. Ukusetshenziswa kwabo okubanzi kuzuzisa ekusebenzeni kwabo okuhle kanye nenqubo yokukhiqiza evuthiwe. Ngakho-ke, iyini ngempela inqubo yokukhiqiza amapayipi e-PVC?
Amapayipi e-PVC akhiqizwa ngenqubo yokukhipha izinto zokusetshenziswa ze-PVC futhi ngokuvamile ahambisana nezinqubo ezivamile zokusebenza kokukhipha amapayipi okujwayelekile: Okokuqala, ama-pellets aluhlaza noma impushana ifakwa kuI-PVC twin screw extruder. Ngemuva kwalokho, ukuncibilika nokushisa kwenziwa ezindaweni eziningi ze-extruder. Le nqubo ibonakala ilula ebusweni, kodwa empeleni, ihilela ubuchwepheshe obuyinkimbinkimbi kanye nezixhumanisi zenqubo, kanye nochungechunge lwemishini yobuchwepheshe kanye nemigqa yokukhiqiza, phakathi kwayo kukhona abanye abamele embonini ye-plastic extrusion yaseChina.
Emgqeni wokukhiqiza wamapayipi e-PVC, i-extruder ngokungangabazeki iyimishini eyinhloko. I-extruder yenza umsebenzi obalulekile wokuguqula izinto zokusetshenziswa zibe amapayipi akhiwe kuyo yonke inqubo yokukhiqiza. Uma sithatha imboni yaseChina ye-plastic extrusion njengesibonelo, amabhizinisi amaningi abelokhu ehlola futhi esungula izinto ezintsha kulo mkhakha. Ngokwesibonelo, u-Blesson, umkhiqizi owaziwayo wase-China, unolwazi olucebile kanye nempumelelo evelele ocwaningweni, ekuthuthukisweni nasekukhiqizweni kwama-extruder.Umshini wokukhipha kaBlessonifektri yamukela ubuchwepheshe obuthuthukisiwe nezinqubo, futhi ama-extruder akhiqizwayo anezinzuzo ezibalulekile mayelana nokunemba, ukuzinza, nokusebenza kahle kokukhiqiza, okuhlinzeka isiqinisekiso esiqinile sokukhiqizwa kwekhwalithi ephezulu yamapayipi e-PVC.
Lapho i-PVC twin screw extruder isebenza, isakhiwo saso sesikulufa siklanywe ngobuhlakani. Izikulufu ezimbili ziyasebenzisana ukuze izinto zokusetshenziswa zikwazi ukuya phambili ngokulinganayo ngaphansi kokusunduzwa kwezikulufu futhi kancane kancane ziqedele izinqubo zokushisisa nokuncibilika ezindaweni eziningi. Endaweni yokuqala, izinto zokusetshenziswa zivame ukushiswa kuqala ukuze ama-pellets noma impushana iqale ukuthamba, kube lula ukucutshungulwa okulandelayo. Njengoba izinto zokusetshenziswa zihanjiswa ngezikulufo endaweni yesibili, izinga lokushisa lizokhuphuka ngokuqhubekayo. Ngalesi sikhathi, i-PVC iqala ukuncibilika kancane kancane futhi yakhe ukuncibilika ngoketshezi oluthile. Kule nqubo, uhlelo lokushisa lwe-extruder ludlala indima ebalulekile. Ukulawula izinga lokushisa okunembile kungaqinisekisa ukuthi izinto zokusetshenziswa ze-PVC ziyancibilika ezingeni lokushisa elifanele, ukugwema umthelela wekhwalithi yamapayipi ngenxa yokushisa okuphezulu kakhulu noma okuphansi. Isibonelo, uma izinga lokushisa liphezulu kakhulu, lingase libangele ukubola kwe-PVC, okuholela ezinkingeni ezifana nokushintsha umbala kanye nokuqina kwamapayipi; kuyilapho uma izinga lokushisa liphansi kakhulu, ukuncibilika ngeke kwanele, futhi umphumela wokwenza amapayipi uyoba mubi, nokukhubazeka okungenzeka okufana nendawo engalingani kanye nesakhiwo sangaphakathi esingalingani.
Ngemuva kokuthi izinto zokusetshenziswa ze-PVC zincibilikisiwe ku-extruder, zingena esigabeni sokwenza. Kulesi sigaba, ukuncibilika kwe-PVC kukhishwa ngesikhunta esithile ukuze kwakheke umumo wokuqala wepayipi. Ukwakhiwa kanye nokukhiqizwa kwe-isikhuntaibe nomthelela omkhulu kwikhwalithi yokugcina yepayipi le-PVC. Isikhunta sekhwalithi ephezulu singaqinisekisa ukunemba kobukhulu, ukufana kodonga, nokushelela kwendawo yamapayipi. Njengomkhiqizi ochwepheshe we-extruder wase-China, u-Blesson utshale imali enkulu yezinsiza zocwaningo nentuthukoisikhuntaukuklama nokukhiqiza, futhi isikhunta esikhiqizayo singahlangabezana nezidingo zokukhiqiza zamapayipi e-PVC emininingwane ehlukene kanye nezimo ezihlukene zohlelo lokusebenza.
Ngemuva kokuthi amapayipi ekhishiwe, adinga ukupholisa nokulinganisa. Le nqubo ngokuvamile ifinyelelwa ngamathangi amanzi okupholisa noma izinto zokupholisa umoya. Amanzi okupholisa kuithangi lamanzi okupholisaizosusa ukushisa kwamapayipi, iwenze apholile futhi abe nosayizi ngokushesha. Ukulawulwa kwejubane lokupholisa nakho kubalulekile. Uma isivinini sokupholisa sishesha kakhulu, singabangela ukucindezeleka kwangaphakathi emapayipini, okuthinta izakhiwo zabo zemishini; kanti uma ijubane lokupholisa lihamba kancane, lizonciphisa ukusebenza kahle kokukhiqiza futhi lingabangela ukuthi amapayipi aguge ngesikhathi senqubo yokupholisa.
Ngaphezu kwezixhumanisi eziyinhloko ezingenhla, inqubo yokukhiqiza amapayipi e-PVC ihlanganisa nezinqubo ezifanakhipha iyunithifuthiukusika. Iyunithi yokuthutha inesibopho sokudonsa amapayipi akhishwe phambili ngesivinini esingaguquki ukuze kuqinisekiswe ukuqhubeka nokuzinza kokukhiqizwa kwamapayipi. Isivinini sokukhipha iyunithi sidinga ukufanisa isivinini se-extrusion. Uma isivinini sokudonsa sishesha kakhulu, amapayipi azokwelulwa futhi abe mncane; kuyilapho uma ijubane lihamba kancane, amapayipi azonqwabelana, okuthinta ukusebenza kahle kokukhiqiza. Idivayisi yokusika isika amapayipi emikhiqizweni eqediwe ngokuya ngobude obubekiwe. Kweminye imigqa yokukhiqiza enezinga eliphezulu lokuzenzakalela, inqubo yokusika ingafinyelela ukunemba okuphezulu kobude obungaguquki bokusika, ukunciphisa amaphutha abangelwa imisebenzi yezandla.
Embonini yaseChina yokukhipha amapayipi epulasitiki, abakhiqizi bepulasitiki baseShayina abanjengoBlesson bahlala bekhuthaza ukuthuthukiswa kwemboni. Abagcini ngokusungula izinto ezintsha kuphela kubuchwepheshe bokukhiqiza imishini kodwa futhi benza ucwaningo olunzulu mayelana nokuklama okuphelele kanye nokwenza kahle kwemigqa yokukhiqiza. Isibonelo, ngokulungiselelwa okudidiyelwe kwe-extruder, i-extrusion die, isistimu yokupholisa, iyunithi yokukhipha, kanye ne-cutter, ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo wayo wonke.Umugqa wokukhiqiza ipayipi le-PVCathuthukisiwe. Ngaleso sikhathi, ngoshintsho oluqhubekayo lwesidingo semakethe, laba bakhiqizi nabo bacwaninga ngenkuthalo futhi bathuthukisa izinhlobo ezintsha zama-extruder nemigqa yokukhiqiza ukuze kuhlangatshezwane namazinga aphezulu okukhiqiza kanye nezidingo eziyinkimbinkimbi zokufaka izicelo.
Kusukela ekukhethweni nasekuphathweni kwezinto zokusetshenziswa kuya ekuncibilikeni nasekushisiseni ku-extruder, bese kuya ekubumbeni, ukupholisa, ukudonsa, nokusika izinqubo, inqubo yokukhiqiza amapayipi e-PVC iyinqubo eyinkimbinkimbi futhi ebucayi. Sonke isixhumanisi sidinga ukulawula nokuphathwa okuqinile, futhi noma yiliphi iphutha elincane lingathinta ikhwalithi yomkhiqizo wokugcina. Ngenxa yemizamo yamabhizinisi amaningi kanye nezingcweti embonini ye-plastic extrusion yaseChina, ikakhulukazi abaholi bezimboni abafana no-Blesson, ngokusungula izinto ezintsha zobuchwepheshe kanye nokuthuthukiswa kwenqubo, ukukhiqizwa kwamapayipi e-PVC aseShayina kuphinde kwazuza ukuncintisana okuqinile emakethe yamazwe ngamazwe. Kungakhathaliseki ukuthi ekwakheni amanzi kanye nezinhlelo zokudonsa amanzi, ukuchelela ngenkasa kwezolimo, noma emikhakheni yezimboni efana namandla amakhemikhali namandla kagesi, amapayipi e-PVC akhiqizwa e-China azuze ukuqashelwa okubanzi ngekhwalithi yawo ethembekile. Ngokuqhubeka okuqhubekayo kwesayensi nobuchwepheshe, kukholakala ukuthi inqubo yokukhiqiza amapayipi e-PVC izoqhubeka nokuthuthukisa futhi ithuthuke, ibe negalelo elikhulu ekwakhiweni kwengqalasizinda yomhlaba wonke nasekuthuthukisweni kwezimboni.
Mayelana nokuvikelwa kwemvelo, ngokugcizelela okwandayo ekuvikelweni kwemvelo emphakathini, amabhizinisi okukhiqiza amapayipi e-PVC nawo ahlala ehlola izinqubo zokukhiqiza eziluhlaza.
